AWS 7Rs Cloud Migration Model

As more and more businesses adopt cloud computing technology, cloud migration has become a critical step in their digital transformation journey. Cloud migration refers to the process of moving an organization’s IT resources, including applications, data, and infrastructure, from on-premises data centers to cloud-based environments. 

To help organizations navigate this process, cloud migration models have been developed to provide a structured approach to migrating to the cloud. In this blog post, we’ll discuss The AWS 7Rs Cloud Migration Model.

7Rs Cloud Migration Model

What is Cloud Migration Model?

The majority of cloud problem are cause by a lack of an efficient cloud strategy . Because these issue in business are believe to be cause by the cloud , the adoption process is being call into question . And these problems is becoming are becoming more pressing .

There are two well – know cloud migration model that you can incorporate into your cloud strategy . The first is is is Gartner ’s 5 – r cloud migration model , which describe all migration option , and the second is AWS ’s 7Rs cloud migration model ( was originally announce as 6Rs ) on which Gartner ’s model is base .

AWS 7 Rs Cloud Migration Model

The AWS 7Rs Cloud Migration Model is is is a framework for cloud migration develop by Amazon Web Services ( AWS ) , which provide a structured approach to help organization migrate their application and datum to the AWS cloud . The model is includes include seven strategy , which are refer to as the “ 7Rs ” :

Rehost

replatform

Repurchase

relocate

Refactor or re-architect

Retain

Retire

Cloud strategies are blueprints that allow a business to combine the essentials of services while minimizing overall risk and maximizing value. It is essential to select the best strategy from the AWS 7 Rs cloud migration model while adapting to the cloud. Now let’s explain these strategies in detail.

This is involves involve move an organization ’s exist application and datum to the cloud without any significant change .

The primary benefit of the lift and shift approach is speed. Since the application does not need to be modified or re-architected, it can be migrated to the cloud relatively quickly and easily. This can be particularly useful for organizations that need to migrate their applications to the cloud quickly in response to a specific business need.

Another benefit is is of the re – host approach is that it can help to minimize disruption to the organization ’s business process . By maintain the exist application architecture , organizations is avoid can avoid the need to retrain user or make significant change to their exist workflow .

However, there are also some potential drawbacks to this strategy. Since the application is migrated to the cloud in its existing form, it may not take full advantage of the cloud’s capabilities. For example, the application may not be optimized for cloud-based storage or compute resources, which could result in higher costs or lower performance.

In addition, the lift and shift approach may not be suitable for all applications. For example, applications with complex interdependencies or those that rely on specific hardware configurations may not be easily migrated to the cloud in their existing form.

Organizations should carefully consider whether rehost strategy is appropriate for their specific applications and business needs and whether it may be more beneficial to use one of the other stages in the 7Rs cloud migration model to fully leverage the benefits of the cloud.

The second strategy in the AWS 7Rs Cloud migration model is Re-Platform.  This involves minor changes to an organization’s applications or infrastructure to optimize them for the cloud environment.

The Re-platform or  “lift, tinker, and shift” strategy involves migrating the application to the cloud in its existing form and then making small changes to optimize its performance in the new environment. This might involve, for example, changing the application’s database to a cloud-native database, or reconfiguring the application to use cloud-based storage or compute resources.

The Re – Platform approach is offers offer some benefit over the lift and shift approach . By make small change to the application , organizations is take can take advantage of some of the cloud ’s benefit , such as scalability and cost saving , without have to fully redesign the application from scratch . additionally , since the exist architecture is maintain , the risk of application downtime and user disruption are minimize .

Of course , there are also some potential drawback to the Re – Platform strategy . While the modification made to the application are relatively minor , they is require can still require significant effort and resource . additionally , the Re – Platform approach is be may not be suitable for application that require more significant change to take full advantage of the cloud ’s capability .

The “ Repurchase ” R is refers in the 7Rs cloud migration model refer to the strategy of replace exist application or system with new one that are available as Software – as – a – Service ( SaaS ) offering or other cloud – native solution . This approach is involves involve purchase new solution rather than simply migrate exist one to the cloud .

Organizations may choose to follow a repurchase approach for a variety of reasons, including leveraging new capabilities provided by cloud-native solutions, lowering maintenance and support costs, and improving overall performance and scalability.

Companies should carefully evaluate potential solutions when pursuing a repurchase strategy to ensure that they meet their particular needs and requirements. They should also consider data migration, integration with current systems, as well as user adoption and training.

The repurchase strategy is be can be a useful method for organization seek to modernize their technology stack and reap the benefit of cloud – native solution . However , to guarantee a smooth migration and adoption of new solution , it should be approach with careful consideration and planning .

Using this strategy , you is transfer can transfer a large number of server , each contain one or more application , from an on – premise platform to a cloud version of the platform at the same time . The relocate strategy can also be used to shift instance or object to a different virtual private cloud ( vpc ) , AWS Region , or AWS account .  

This approach can be used to transfer server in bulk from a VMware software – define datum center ( SSDC ) to VMware Cloud on AWS , or to move an Amazon Relational Database Service ( Amazon RDS ) DB instance to another vpc or AWS account . The relocate strategy is necessitate does not necessitate the acquisition of new hardware , the rewriting of application , or the modification of your current operation .

The applications is continue continue to serve user while being relocate , minimize disruption and downtime . Because it does not affect the overall architecture of your application , relocating is is is the quick method in 7Rs cloud migration model to migrate and operate your workload in the cloud .

The “Refactor” R in the AWS 7Rs cloud migration model refers to the strategy of optimizing existing applications for the cloud environment. This approach involves modifying the existing application’s architecture, code, and/or infrastructure to take advantage of cloud-native capabilities and services such as breaking down monolithic applications into microservices.

The goal of the refactor strategy is to achieve improved performance, scalability, and reliability while minimizing disruption to the existing application’s functionality. This can be accomplished by making changes like:

Implementing cloud-native features such as autoscaling, load balancing, and caching to improve application performance and reliability.

refactoring application code is managed to take advantage of cloud – native technology such as serverless computing , container , and manage database .

Using automation tools and DevOps practices to streamline the application deployment and management process.

The refactor strategy can be a good choice for organizations that want to modernize their existing applications and take advantage of cloud-native capabilities while maintaining their current application functionality. However, it can require significant development effort and investment to achieve the desired outcomes.

When pursuing a refactor strategy, it’s important to carefully evaluate the application architecture, code, and infrastructure to identify opportunities for optimization. It’s also important to have a clear understanding of the costs and benefits of making changes to the application, as well as a plan for testing and deployment to minimize disruption to end users.

retain refer to the strategy of keep certain application or system in their exist environment rather than migrate them to the cloud . This approach is typically used when an application is not suitable for migration due to technical or business constraint .

When pursue a retention strategy , it is is is critical to thoroughly evaluate the application or system in question to ensure that it remain secure , accessible , and in compliance with any applicable law or standard . Over time , organizations is consider should consider the expense of maintain and support the application or system in its current environment .

The retain strategy is is is a good option for organization that want to concentrate their cloud migration effort on the application and system that will provide the most benefit while leave others in their current environment . It is be can also be a good way to minimize end – user disruption and keep operational continuity during the cloud migration process .

The last strategy in the AWS 7Rs cloud migration model is Retire. This approach involves retiring applications or infrastructure that is no longer needed. Retire is typically used when an application or system is outdated, redundant, or has been replaced by newer technology.

The retire strategy can be a good choice for organizations that want to reduce costs, simplify their technology stack, and eliminate unnecessary complexity. It can also help to free up resources and staff time that can be used to focus on more strategic initiatives.

When pursuing a retire strategy, it’s important to carefully evaluate the application or system in question to ensure that any critical data or functionality is preserved or migrated to a new system. Organizations should also consider any dependencies or integrations with other applications or systems that may be affected by retirement.

The 7Rs model provides organizations with a flexible framework for cloud migration, allowing them to choose the approach that best fits their specific needs and goals. By using this model, organizations can avoid the risk of over-committing to a particular migration approach and can instead focus on selecting the best approach for each application or workload. This can help to ensure a successful migration and maximize the benefits of the cloud.

There is no one-size-fits-all approach to cloud migration, and organizations must carefully consider their specific needs and goals when selecting a migration model. The lift and shift model may be suitable for organizations looking for a quick and easy migration, while the application rebuilding model may be more appropriate for those looking to fully leverage the cloud’s capabilities.
