The 7Rs of Cloud Migration: An Overview

The 7Rs of Cloud Migration can be thought of as a roadmap to guide organizations through the complex process of migrating their IT infrastructure to the cloud. Each of the 7Rs is a different migration strategy, and businesses can make sure their move to the cloud goes well by understanding and using these strategies. The 7Rs are as follows: Relocate, Rehosting, Replatforming, Repurchasing, Refactoring, Retire, and Retain.

Each of these strategies has its own set of advantages and challenges, and the best approach for your organization will depend on your unique needs, resources, and goals. By giving each of the 7Rs careful thought and applying them to your specific situation, you can improve your cloud migration process and make your business more efficient and flexible as a whole. In the sections that follow, we'll talk more about each of these strategies and explain how you can use them effectively on your journey to the cloud.

Relocate: Move your workload using native tooling

Relocate, which is also called "Move Migration," is a cloud migration strategy that moves workloads to the cloud using the cloud service provider's own tools like moving from on-prem VMWare to Cloud VMWare. This method is best for organisations that want to make their migration as simple as possible by using cloud-native tools and services they already have. In this scenario, businesses can focus on moving their data and applications as-is without the need for extensive redesign or modification.

The advantages of the Relocate strategy are that it makes moving easier, gets you to market faster, and costs less up front. This method also lets organisations quickly see the benefits of cloud computing, such as better scalability, flexibility, and cost-effectiveness. But it's important to remember that this strategy might not work for all workloads, as some applications may need more extensive changes to use cloud-native features and services to their fullest.

For a Relocate migration to go smoothly, organisations should carefully look at their workloads and figure out which ones can be moved with the least amount of change. They should also learn about the native tools offered by the cloud service provider they choose and make sure they have the skills and resources they need to use these tools effectively during the migration process.

Rehosting: The "Lift-and-Shift" Migration Strategy

Rehosting, commonly known as the "Lift-and-Shift" strategy, involves moving applications and data from on-premises infrastructure to the cloud without making significant changes to the underlying architecture. This approach is best suited for organizations that want to quickly and efficiently migrate their workloads to the cloud without the need for extensive refactoring or redesign.

The main advantage of the Rehosting strategy is its simplicity, as organizations can quickly move their workloads to the cloud with minimal disruption to their operations. This approach also allows businesses to begin reaping the benefits of cloud computing, such as increased scalability, flexibility, and cost-efficiency, almost immediately. However, it's important to note that the Rehosting strategy may not be suitable for all workloads, as some applications may require more extensive modifications to fully leverage cloud-native features and services.

Often, this migration strategy can result in higher cloud costs, so businesses should also carefully consider the potential cost savings and operational improvements that can be achieved through cloud migration and weigh these against any potential challenges or limitations associated with the Rehosting strategy.

Replatforming: The "Lift-and-Reshape" Migration Strategy

Replatforming, also called the "Lift-and-Reshape" strategy, involves moving applications and data from on-premises infrastructure to the cloud while making small changes to the architecture. For example, a self-managed MySQL database could be moved to a fully managed MySQL service. This method works best for organisations that want to optimise their workloads for the cloud without having to do a lot of redesigning or refactoring.

The main advantage of the Replatforming strategy is that it allows organizations to take advantage of cloud-native features and services without the need for significant changes to their existing applications. This can result in improved performance, scalability, and cost-efficiency, as well as reduced operational complexity.

To ensure a successful Replatforming migration, organizations should carefully assess their workloads and determine which ones can be optimized for the cloud with minimal modifications. They should also consider the potential cost savings and operational improvements that can be achieved through cloud migration and weigh these against any potential challenges or limitations associated with the Replatforming strategy.

Repurchasing: Migrating to a New SaaS Platform

Repurchasing, also called the "Drop-and-Shop" strategy, means moving from on-premises or self-hosted apps to Software as a Service (SaaS) platforms in the cloud. This method is ideal for organisations that want to benefit from the scalability, flexibility, and low cost of SaaS solutions without having to significantly refactor or redesign their existing applications.

The main advantage of the Repurchasing strategy is that it allows organizations to quickly and easily transition from legacy systems to modern, cloud-based solutions that are designed to meet the demands of today's digital landscape. This can result in significant cost savings, as well as improved operational efficiency and agility. However, it's important to note that the Repurchasing strategy may not be suitable for all workloads, as some applications may require more extensive modifications or customization to fully leverage the benefits of SaaS platforms.

To ensure a successful Repurchasing migration, organizations should carefully assess their workloads and determine which ones can be effectively replaced by SaaS solutions. They should also consider the potential cost savings, operational improvements, and strategic advantages that can be achieved through cloud migration and weigh these against any potential challenges or limitations associated with the Repurchasing strategy.

Refactoring: Redesigning Applications for Cloud-native Architecture

Refactoring, also known as "Re-Architecting" or "Application Modernization," involves redesigning applications to take full advantage of cloud-native features and services. This approach is best suited for organizations that want to optimize their workloads for the cloud and fully leverage the benefits of cloud computing. Refactoring requires a significant investment in time and resources compared to other migration strategies, but it can result in substantial long-term benefits, such as improved performance, scalability, and cost-efficiency.

The main advantage of the Refactoring strategy is that it allows organizations to create applications that are specifically designed for the cloud, enabling them to take full advantage of the features and services offered by cloud platforms. This can result in significant operational improvements and cost savings, as well as increased flexibility and agility. However, it's important to note that the Refactoring strategy can be more complex and time-consuming than other migration strategies, as it requires a complete redesign of the application architecture.

To ensure a successful Refactoring migration, organizations should carefully assess their workloads and determine which ones would benefit most from a cloud-native architecture. They should also consider the potential cost savings, operational improvements, and strategic advantages that can be achieved through cloud migration and weigh these against the time and resources required for the Refactoring process.

Retiring: Removing Unnecessary Applications and Services

Retiring is a cloud migration strategy that involves figuring out which applications and services you don't need and getting rid of them. This method works best for organisations that want to simplify their operations, cut costs, and improve overall efficiency by getting rid of unnecessary or old systems.

The main benefit of the Retire strategy is that it lets businesses focus on the applications and services that are most important to them. This improves operational efficiency and saves money. By getting rid of tasks that aren't necessary, businesses can free up valuable resources that can be put towards more strategic projects, like moving to the cloud or making the business more digital. However, it's important to note that the Retire strategy requires a thorough assessment of your IT environment to identify any potential risks or dependencies associated with the removal of specific applications or services.

To make sure a Retire migration goes well, organisations should carefully look at their IT environment and find any applications or services that are no longer needed or can be replaced with more efficient cloud-based alternatives. They should also think about how migrating to the cloud could save money, improve operations, and give them strategic advantages. They should weigh these benefits against any risks or dependencies that might come with the Retire strategy.

Retain: Keeping Certain Applications on-premises

Retain is a cloud migration strategy where some apps and services stay on-premises while others move to the cloud. This method works best for organisations that have workloads that can't be easily moved to the cloud, like apps that have to follow strict compliance rules or legacy systems that are deeply embedded in the infrastructure of the organization.

The main advantage of the Retain strategy is that it allows organizations to maintain control over specific applications and services while still benefiting from the advantages of cloud migration for other workloads. This can result in improved operational efficiency, cost savings, and increased flexibility and agility. However, it's important to note that the Retain strategy requires careful planning and management to ensure that the on-premises and cloud-based environments are effectively integrated and optimized.

To make sure that a Retain migration goes well, organisations should carefully look at their workloads and figure out which applications or services should stay on-premises and how they will interact with the workload migrated to the cloud.
