AWS vs Azure Cloud Migration Cost Comparison Explained (2026 UK Business Guide)

Cloud migration is a major investment for businesses operating in UK, which makes cost assessment one of the very important aspects when selecting a cloud platform. While AWS and Azure both provide secure cloud environments, the migration cost can still differ based on current infrastructure requirements, storage needs, and operational expenses.

The cloud migration market in the UK is growing rapidly. Based on a report, the cloud migration market in UK is expected to surpass US$2378.2 billion in 2030. This growth highlights the rising adoption of cloud technologies in every industry.

AWS and Azure are currently dominating the cloud market; however, which platform offers better value remains highly dependent on individual business requirements. In this guide, we’ll compare AWS and Azure cloud migration costs and key pricing components to help UK businesses make an informed decision.

Understanding Cloud Migration Costs Before Comparing AWS and Azure

Before making a comparison between Azure and AWS pricing, it is necessary to know which factors affect cloud migration cost. Cloud migration cost goes well beyond the cost of migrating workloads from the traditional environment to the cloud. Other costs may include assessing the current situation, modifying the application and managing the cloud after migration. Knowing these cost components will help businesses create more accurate budgets and avoid any additional costs.

The cloud migration cost includes all expenditures required to migrate applications and business workloads from the local infrastructure or another cloud environment to a new one.

Example:

A UK retail company migrating its eCommerce platform from local servers to AWS may incur costs for workload assessment and database migration, and cloud infrastructure provisioning before the migration is fully completed.

Direct vs Indirect Migration Expenses

Cloud migration costs generally fall into two categories: direct and indirect expenses.

Direct costs include:

• Cloud infrastructure setup
• Data migration tools
• Consulting and implementation services
• Software licensing
• Security and compliance configurations

Indirect costs include:

• Employee training
• Temporary productivity losses
• Downtime during migration
• Internal IT resource allocation
• Change management activities

One-Time Costs vs Ongoing Cloud Costs

Some migration expenses occur only during the migration process, and others continue throughout the cloud lifecycle.

One-time costs:

• Cloud readiness assessments
• Data migration
• Application refactoring
• Initial cloud configuration
• Testing and deployment

Ongoing costs:

• Virtual machines
• Storage services
• Networking and bandwidth
• Security monitoring
• Managed support plans

Components of Cloud Migration Cost

Business Size	Estimated Cloud Migration Cost	Timeline
Small Business	£5,000 – £15,000	1–2 months
Mid-Sized Business	£15,000 – £50,000	2–6 months
Large Enterprise	£50,000 – £200,000+	6–10 months

The real cost of migration varies based on several considerations like the intricacy of the workload, the amount of data, architectural design of applications, compliance regulations, and the extent of cloud optimisation needed after migration. These estimates help analyse Azure and AWS migration costs discussed in the subsequent sections.

AWS vs Azure Market Position in the UK Cloud Computing Industry

The two dominant cloud players in the market are AWS and Azure to help businesses undertake successful digital transformation initiatives such as application deployment, data analysis, machine learning, and cloud native development. Both providers are known to offer a wide array of cloud solutions; however, adoption rates are likely to depend on the technology already implemented by the firms and their business goals.

AWS Adoption Across UK Enterprises

AWS is a popular choice among UK companies that seek scalable and flexible cloud computing solutions for their projects. As such, many UK-based companies leverage the AWS services to deploy applications and analyse their data using machine learning tools.

Also, a report states that Amazon Web Services accounted for approximately 28% of the global cloud infrastructure services market, which makes it the largest cloud provider.

Azure’s Strength in Microsoft Ecosystems

Microsoft Azure is particularly known among businesses that already use Microsoft technologies. Companies using Windows Server or SQL Server find Azure cloud migration better because of the integration capabilities and licensing.

Organisations implementing hybrid cloud strategies also prefer to utilise Azure since it enables such organisations to combine on-premises infrastructure with cloud infrastructure in a seamless manner.

UK Public Sector and Enterprise Preferences

While AWS and Azure are used extensively in both UK private and public sectors, it is seen that AWS is used more commonly in cloud first projects and digital transformation initiatives, whereas Azure is chosen for organisations having investments in Microsoft systems.

In addition to this, industries ranging from banking to government departments are increasingly adopting cloud migration services.

Which Cloud Provider Is Growing Faster?

The demand for cloud services in the UK continues to grow. A report shows that the cloud computing market in UK will be US$64.97 billion in revenue in 2026, which reflects the growing enterprise cloud investment.

Although AWS will remain dominant because of its cloud services infrastructure, Azure has been growing quickly because of its role in the Microsoft ecosystem and its wide customer base consisting of many enterprises. 

Migration Strategy Impact on Cost (AWS vs Azure)

The cloud migration strategy can play an essential role in terms of both the initial cost of migration and ongoing cloud costs in the future.

Lift & Shift (Rehost)

In Lift & Shift, applications are migrated to the cloud with only minor changes made to their architecture.

Key Aspects:

• Least upfront migration cost
• Shorter deployment timeline
• Least amount of application modification
• Highest ongoing operation cost due to lack of optimisation

This type of strategy is used by companies in cases where fast migration with minimum disturbance is needed.

Replatform

In this type of migration strategy, minimal modifications are made to applications to enable their use of cloud-specific services without having to change their architecture.

Key Aspects:

• Somewhat higher migration cost
• Enhanced scalability and performance
• More efficient than the previous type of migration strategy
• Reduced infrastructure requirement

A lot of organisations adopt this strategy as a balance between speed and optimisation.

Refactor

In this type of migration strategy, minimal modifications are made to applications to enable their use of cloud-specific services without having to change their architecture.

Key Aspects:

• High initial cost and effort required
• Best performance and scalability
• Least ongoing cost of cloud

This approach is chosen for business critical applications with growth requirements.

Rebuild

This migration strategy will result in the development of an entirely new cloud-native application rather than transforming the current application.

Key Aspects:

• Highest migration investment
• Most cloud optimisable
• Flexible and scalable
• Longest migration process

Companies adopt this migration approach mainly where their legacy applications do not fit into the organisation’s operations anymore.

Cost Impact by Migration Strategy

Strategy	AWS Cost Impact	Azure Cost Impact
Rehost	Low upfront investment, higher long-term runtime costs	Similar cost profile with potential hybrid-cloud savings
Replatform	Moderate investment	Moderate investment with potential PaaS savings
Refactor	Higher upfront investment	Higher upfront investment with strong enterprise tooling benefits
Rebuild	Very high investment	Very high investment

The best strategy for cloud migration in UK is based on your business goals and ROI. Rehosting can be the fastest, but refactoring and rebuilding can deliver better optimisation benefits.

AWS vs Azure Cloud Migration Cost Comparison

In terms of comparing AWS migration costs with Azure migration costs, there is no definite answer since the pricing depends on many other factors. Generally, AWS gives flexibility, whereas Azure will bring cost benefits for organisations that are already using Microsoft products.

AWS vs Azure Cost Comparison Overview

Cost Factor	AWS	Azure
Initial Setup	£8,000–£40,000	£7,000–£35,000
VM Costs	£500–£6,000/month	£450–£5,800/month
Storage Pricing	£150–£3,500/month	£160–£3,700/month
Networking Costs	£300–£4,000/month	£350–£4,200/month
Hybrid Cloud	£5,000–£30,000	£4,000–£25,000
Licensing Benefits	£2,000–£15,000 savings	£5,000–£25,000 savings
Support Plans	£250–£8,000/month	£250–£7,500/month
Compliance Costs	£2,000–£20,000	£2,000–£18,000

AWS provides competitive prices for storage and network solutions, which are important for cloud-native solutions. Azure usually becomes cheaper than AWS if companies are running Windows Server, SQL Server and other Microsoft software.

Storage Migration Costs: AWS S3 vs Azure Blob Storage

The cost of storage is an important part of Azure and AWS cloud migration costs, especially when it comes to migrating vast amounts of business data, backups, media files, and application content. The object storage service used in AWS is S3, while for Azure it is Blob storage. Both services provide businesses with scalable and durable storage solutions.

Object Storage Pricing Comparison

Both services utilise a pay-for-use pricing strategy; hence, companies pay based on how much storage space they use, how many requests they generate, and how much data they transfer. The cost varies depending on which storage class you choose and the frequency of data access.

When it comes to high-performing storage for frequently accessed business applications, AWS and Azure have services that ensure low latency and quick access.

Archive and Backup Storage Costs

Firms with compliance, disaster recovery, or retention requirements may benefit from lowering their costs through archiving storage. There are multiple storage classes on AWS like S3 Glacier and Glacier Deep Archive, and similar classes on Azure, like Cool and Archive storage tiers.

Data Retrieval Charges

As much as archive storage cuts down the monthly costs associated with storage, organisations need to take into consideration data retrieval fees. The cost of retrieving archived data can be higher than other forms of storage, and can be time-consuming too.

Long-Term Storage TCO Analysis

In determining storage costs, companies should consider the total cost of ownership beyond storage. Some of the considerations when calculating storage cost include the rate of data access, data backup, compliance, replication, and data growth.

AWS is often slightly cheaper in some cases for archiving storage, whereas Azure is always very competitive where organisations are already using the Microsoft environment.

Data Transfer and Networking Costs Explained

Network and data transfer costs can play an important role in determining overall AWS and Azure migration costs, particularly when there are large volumes of data to migrate or customer traffic. Both cloud service providers use different fee models depending on whether data is migrating within or outside the cloud environment, making pre-migration analysis essential.

Inbound vs Outbound Data Charges

It should be noted that both AWS and Azure charge little or no cost for inbound data transfers to their respective clouds. Outbound data transfers are typically charged according to the volume of data being transmitted outside of the cloud.

For instance, the transfer of substantial amounts of product data to users by a UK-based eCommerce business would result in additional fees being paid to AWS or Azure, based on the number of users accessing the website.

Inter-Region Transfer Fees

Extra charges may apply when data is transferred between cloud regions. These costs are relevant for businesses using disaster recovery environments or multi-region deployments.

For example, a financial services company replicating data between UK and European cloud regions for business continuity will incur ongoing inter-region transfer costs.

CDN and Edge Network Costs

The use of AWS CloudFront and Azure CDN improves application performance by distributing content via edge nodes located geographically close to customers.

Although CDNs add to the overall cost of cloud solutions, they also help reduce traffic usage and increase site speed.

Thus, online stores can leverage CDNs to deliver their website images faster during peak traffic periods. According to cloud migration professionals, one of the most underestimated cloud-related costs is network connectivity.

Migration Tools Comparison: AWS Migration Hub vs Azure Migrate

Migration tools make cloud migration more efficient by reducing costs, time, and complexity. Both AWS and Azure have developed their own migration platforms to make the process easier, including workload assessment, dependency discovery, cost estimation, and AI automation of migration activities.

AWS Migration Hub Features

Some of the migration tools available within AWS include application discovery, migration monitoring, server migration, database migration, and migration project progress.

It provides organisations with a comprehensive approach to large-scale migration management, enabling them to track multiple workloads.

Azure Migrate Features

Azure Migrate provides users with a unified approach to migrate servers, databases, applications, and virtual desktops to Azure through discovery, assessment, and migration of applications. This makes it easy for companies with Microsoft-based workloads, such as Windows Server and SQL Server.

The tool allows organisations to estimate the cloud readiness and infrastructure cost estimation before migration.

Assessment and Discovery Costs

AWS Migration Hub and Azure Migrate both provide basic assessment and discovery features free of additional cost. Nevertheless, companies might incur additional costs due to third-party migration tools, consultancy services, application modernisation, and other testing costs.

Proper workload discovery will help companies identify dependencies across resources and avoid additional costs during migration further down the road.

Automation and Migration Speed

Automation capabilities will enable companies to save time and reduce the effort required for migration. Both services provide automation options for migrating, tracking workload, and connecting with migration services.

Often, Azure Migrate is advantageous for businesses that rely heavily on Microsoft technology stacks, whereas AWS Migration Hub is known for its flexibility.

Migration Tool Comparison

Feature	AWS Migration Hub	Azure Migrate
Discovery	Yes	Yes
Dependency Mapping	Yes	Yes
Cost Estimation	Available through AWS tools	Built-in assessment and cost estimation
Automation	Extensive migration workflow support	Extensive migration workflow support

Licensing Costs and Microsoft Software Considerations

Licensing considerations can affect Azure or AWS cloud migration costs, especially if the business uses Microsoft applications and systems. Both AWS and Azure can host Windows and SQL Server-based environments, however, Azure tends to have more cost-efficient licensing terms for Microsoft products.

Azure Hybrid Benefit Explained

Azure Hybrid Benefit enables customers to use their on-premises Windows Server and SQL Server licenses in Azure deployments. This allows companies to run Windows and SQL-based machines and databases using cheaper licenses than would be otherwise possible with standard cloud pricing.

According to Microsoft, Azure Hybrid Benefit can help businesses lower costs on eligible Windows and SQL Server workloads. 

Existing Windows Server Licenses

Businesses with existing Windows Server licenses and Software Assurance agreements can utilise them in Azure to minimise licensing costs for Windows environments.

While AWS also hosts Windows servers, Azure offers better licensing options, making Azure the cheaper choice for deploying Microsoft products.

SQL Server Licensing Savings

SQL Server is arguably the most common enterprise database solution. Companies migrating SQL Server-based workloads to Azure will have the opportunity to save on SQL Server licensing through Azure Hybrid Benefit.

When Azure Becomes More Cost Effective

Azure is considered to be more cost-effective for businesses when:

• Have a lot of Windows Servers
• Run several SQL Server databases
• Benefit from pre-existing enterprise deals with Microsoft
• Require hybrid cloud deployment services

For companies that rely heavily on Linux, open-source databases, and native cloud applications, the licensing cost gap between AWS and Azure becomes much less relevant.

AWS vs Azure Security and Compliance Costs for UK Organisations

Compliance Requirements

Both AWS and Azure offer resources needed to become compliant with the GDPR and NHS requirements, including data encryption, identity and access management, auditing capabilities, among other tools.

For example, a healthcare institution moving its patients’ records to the cloud will most likely face extra costs related to increased compliance costs.

ISO 27001 and Cyber Essentials

Azure and AWS both support full compliance with standards like ISO 27001 and Cyber Essentials,  yet organisations may still face compliance-related expenditures associated with security assessments, certifications, documentation, and compliance control.

For example, a financial services firm working towards receiving ISO 27001 certification will allocate some of its budget to audits and security reviews.

Data Residency in the UK

There are various UK firms that have obligations to make sure their customer and business data is always stored in data centres. AWS and Azure offer UK regions that will enable businesses to achieve data residency objectives and comply with regulations.

A governmental organisation or any other organisation operating in the public sector may opt for hosting infrastructure in the UK because of internal policies and regulations.

Security Monitoring Cost Comparison

Costs associated with security monitoring depend on workload size, number of logs and required threat detection among others. Both AWS and Azure offer built-in security monitoring tools that help organisations detect risks and take action.

For instance, a large online retailer with high volumes of customer transactions may opt for enhanced security monitoring solutions to secure their data against cybercrime.

Compliance Cost Factors

Compliance Area	AWS	Azure
GDPR	£1,000–£10,000	£1,000–£9,000
Data Residency	£500–£5,000	£500–£5,000
Monitoring	£1,000–£15,000/year	£1,000–£14,000/year
Auditing	£1,000–£10,000	£1,000–£10,000

Compliance costs for companies in the UK tend to depend more on industry regulations and security considerations rather than the cloud vendor.

Total Cost of Ownership (TCO) Comparison

Evaluating Azure and AWS cloud migration costs requires looking beyond the initial migration budget. Total Cost of Ownership (TCO) includes infrastructure and operational management expenses over time. Although AWS and Azure charge similarly, their long-term costs may differ based on the needs of the workloads and the licensing advantages they provide.

Small Business

For a small business that migrates its website, applications, and files to the cloud, the main objective will be cost-effectiveness. In most cases, AWS and Azure offer similar TCO for a small business seeking affordable, scalable solutions.

Mid-Market Organisation

Unlike the case of a small business, mid-market companies utilise several applications, databases, and customer portals. Therefore, licensing, support, and resource optimisation become crucial in determining the cost of cloud services.

Businesses running Windows Server and SQL Server workloads usually realise greater savings on Azure due to licensing advantages.

Enterprise Migration

In large organisations, there are usually hundreds of workloads migrated into the new cloud and a need for advanced security, compliance, disaster recovery, and governance. Despite high spending compared to other options, cost reduction through reservation of capacity and workload rightsizing can result in significant savings.

Azure could be considered a better choice for companies with a solid Microsoft background. At the same time, AWS is still extremely competitive. To conduct this level of cloud migration, you may need to collaborate with a cloud migration service provider.

TCO Comparison

Time Period	AWS	Azure
1 Year	£12,000–£45,000	£11,000–£42,000
3 Years	£35,000–£120,000	£32,000–£115,000
5 Years	£60,000–£200,000	£55,000–£190,000

Real-World UK Business Migration Cost Scenarios

AWS and Azure cloud migration costs vary from one industry to another depending on infrastructure requirements, regulations, amounts of data, etc. The following examples describe possible costs for UK companies.

A typical retail company investing in cloud migration is spending between £15,000 and £60,000.

Such costs depend on web traffic levels, amounts of data processed and transferred, integration with third parties, etc.

Healthcare Organisation Migration Example

A healthcare provider migrating electronic health records, patient management systems, and clinical applications is spending £40,000 and £200,000.

Healthcare migrations generally require advanced security controls and detailed testing to protect sensitive patient information and meet regulatory standards.

These examples provide a general indication of migration costs. Actual expenses will vary depending on various factors during the migration process.

When AWS Is Cheaper and When Azure Saves More Money

The difference in cost between AWS and Azure is influenced by workload needs, software investment, and future plans in cloud computing. While both service providers offer competitive pricing, in some cases, the choice of service can be financially justified by certain criteria.

Where AWS Delivers Lower Costs

AWS often provides better value for organisations that:

• Run Linux-based workloads
• Build cloud-native applications
• Require a wide range of infrastructure options
• Operate large-scale analytics and containerised environments
• Need flexible consumption-based pricing without Microsoft licensing dependencies

Companies that focus on open-source software tend to see competitive pricing from AWS over time.

Where Azure Provides Better Value

Azure can offer lower overall costs for organisations that:

• Use Windows Server extensively
• Operate SQL Server databases
• Have existing Microsoft enterprise agreements
• Require Azure Hybrid Benefit
• Depend on Microsoft 365, Active Directory, and related services

Licensing savings can decrease total cloud spending.

Hybrid and Multi-Cloud Cost Considerations

Most UK companies use hybrid or multi-cloud architectures to satisfy performance, compliance, and other considerations related to business continuity. Although hybrid clouds allow for flexibility, they could result in extra costs associated with networking and monitoring solutions.

Companies should be careful about their operational complexities in case they want to use workloads across several clouds.

Recommendations from Cloud Architects

Cloud experts always suggest choosing an appropriate cloud migration service provider depending on the workloads, rather than on cost. In most cases, issues such as licensing, operational efficiency, scaleability, security, and potential for optimisation affect the total cost more than pricing itself.

Best Provider by Business Scenario

Business Requirement	AWS	Azure
Microsoft Environment	X	✓
SAP Workloads	✓	✓
DevOps Teams	✓	X
Hybrid Infrastructure	X	✓
AI and Analytics	✓	✓

Azure tends to deliver better value for Microsoft-based infrastructure, but AWS remains a powerful competitor in cloud-native development and large-scale infrastructure projects.

Cost Optimisation Strategies After Migration

Cloud migration is only the first step. To maximise return on investment, businesses should continuously optimise cloud resources and monitor spending. 

While migrating to the cloud may be the first step, companies will need to keep optimising their resources to maximise ROI on both AWS and Azure through effective cost management practices.

Optimal Allocation of Resources

Optimal allocation of cloud resources entails matching them to actual usage. The majority of firms tend to provision more computing resources than required, thereby driving up their costs.

A retail business moving an application to a bigger virtual machine out of caution during migration may find out that smaller VM instances do the same task but charge less per month after analysing resource consumption patterns.

Reserved Capacity Planning

Predictable computing needs will enable firms to minimise their cloud computing costs through committed capacity strategies rather than relying solely on on-demand rates.

For instance, a company running customer management software 24/7 can lower compute costs by purchasing reserved instances.

FinOps Best Practices

FinOps combines financial accountability with cloud operations to improve spending visibility and resource efficiency. Examples of best practices in FinOps are cost assessment, budget management, workload optimisation, and teamwork.

A company that intends to develop a mobile app can apply FinOps practices to evaluate its infrastructure consumption for development, testing, and production to avoid excessive cloud spending.

Automated Cost Governance

By using Artificial Intelligence for automation, companies can monitor their resource usage and detect overages before bills become too high.

For example, a healthcare provider can configure automated policies that shut down unused development environments outside working hours.

AWS vs Azure: Which Cloud Platform Delivers Better ROI?

Best for Microsoft-Centric Businesses

The Microsoft environment is likely to deliver better ROI from Azure when you have significant assets running Windows Server, SQL Server, Microsoft 365, and Active Directory. Using the Azure Hybrid Benefit and having existing enterprise agreements can lower your migration and operational costs.

When a company invests in Microsoft-specific solutions, Azure will bring higher ROI.

Best for Cloud-Native Organisations

AWS is the preferred choice for cloud-native companies developing modern applications with the help of containers, microservices, serverless, and other open-source tools.

Due to its diverse services and infrastructure options, AWS can offer good scaling options and cost efficiency, giving high ROI in most cases.

Best for Hybrid Cloud Deployments

One of Azure’s best strengths lies in its ability to integrate with the already-existing Microsoft infrastructure. The gradual cloudification of businesses, without migrating completely to the cloud, becomes cheaper and easier with Azure, which may lower the risks associated with such a transition.

Best for Enterprise Scalability

AWS and Azure offer comparable scalability for enterprise use, but AWS wins in situations that demand global deployment of services across many cloud locations and extensive use of cloud computing resources.

Azure still remains competitive in cases where a company focuses primarily on Microsoft products, while AWS usually wins the battle when it comes to large cloud-first initiatives.

Common Cloud Migration Cost Mistakes Businesses Make

Underestimating Data Transfer Costs

Companies often focus on how much they will pay for computing and storage resources but neglect data transmission costs, especially those associated with outbound and inter-region traffic.

Solution: Assess your organisation’s data movement requirements prior to migration and consistently track cloud resource utilisation.

Ignoring Application Refactoring Expenses

Legacy applications typically require adjustments to work effectively in the cloud, incurring additional costs.

Solution: During the planning stage, do a comprehensive assessment of the applications and prepare to allocate the funds needed.

Overprovisioning Resources

Organisations tend to spin up larger virtual machines and use excessive storage, increasing overall cloud spend.

Solution: Implement rightsizing practices and continuously review resource utilisation to ensure workloads match actual business needs.

Neglecting Staff Training Costs

The use of the cloud may need some members of an organisation’s IT team to undergo training on new techniques and skills. This cost is always underestimated when doing budgets for migration.

Solution: Incorporating training costs will ensure that team members have the required skills to handle the migrated environment.

How to Estimate Your Cloud Migration Budget Accurately

Accurate budgeting is very important for avoiding unexpected expenses during cloud migration. The right approach helps businesses evaluate infrastructure requirements and estimate both migration and long-term operational costs.

Discovery and Assessment Checklist

There are several things to consider before beginning any cloud migration:

• Applications and workload
• Amount of data and storage space
• Security and regulatory requirements
• Licensing issues
• Network considerations
• Application reconfiguration needs

By conducting a proper assessment, businesses can have a better understanding of what kind of resources they will require in order to migrate successfully.

Building a Migration Roadmap

Migration roadmap allows dividing the project into phases to ensure more accurate cost calculations and minimise implementation risks.

Common phases are evaluation, planning, trial migration, migration, testing, optimisation, and management.

Working with Cloud Migration Service Provider

Professional cloud migration service providers can assist organisations in identifying potential savings, improving their cloud architecture, and minimising risks in their migration projects.

How to Choose the Right Cloud Migration Service Provider

Selecting the best cloud migration service provider can highly influence project success and cloud performance. Businesses should evaluate technical expertise and after migration support before making any decision.

Migration Experience

Cloud migration services experience can be considered one of the most crucial selection criteria. A business should analyse the experience of the company in performing such projects and in specific industries.

Security and Compliance

Security must be considered while choosing a migration company. They need to be experienced in security management and access policy management, and compliant with standards such as GDPR, ISO 27001, and Cyber Essentials.

It is more critical for companies operating in highly regulated industries such as healthcare, finance, and government sectors.

Support and Cost Optimisation

Migration is not just a one-time project. Ongoing support and cost optimisation are essential for maximising cloud ROI.

A reliable cloud migration service provider should offer post-migration services to help businesses maintain efficient cloud operations over the long term.

Final Verdict

AWS and Azure are two of the best platforms that provide better security and scalable services for businesses seeking cloud migration. AWS is preferred for cloud native apps and for flexible infrastructure, whereas Azure can provide cost benefits for businesses already invested in Microsoft technologies through licensing benefits and hybrid cloud capabilities.

The total cost of AWS and Azure cloud migration is based on different factors like workload complexity and data transfer needs. Rather than focusing only on initial migration costs, businesses should analyse the ongoing and future scalability costs as well.

By performing a complete assessment and aligning cloud selection with business goals in UK, organisations can maximise their ROI. Also, partnering with a cloud migration service provider can further help businesses ensure a successful migration process.
