AWS Migration Strategy and Best Practices

When compared to on-premises solutions, cloud computing offers several advantages for businesses today, including lower IT costs, better IT efficiency, ease of use for remote workers, and faster deployment timelines. If you’re looking for a public cloud provider in 2020, you’ll have a lot of possibilities. Many public cloud providers are familiar to you, like Microsoft Azure, Amazon Web Services AWS, IBM Cloud, and the Google Cloud Platform. Your team can also pick and choose which cloud service provider is suitable for your company. We’ll go through Amazon Web Services’ best practices and how your team can benefit from cloud computing in 2020 in this post.

What are AWS Cloud Migration Best Practices?

As the benefits of using the cloud become more apparent, more businesses are shifting their workloads to the cloud. The adoption of technology across all business verticals is the primary driver of this shift. With the introduction of technology, the amount of money spent on resources increases dramatically.

Initially, enterprises choose to host their infrastructure in their data center for a variety of reasons, including flexibility and security. With the expansion of the cloud, fast changing business demands, and expanding technology, more and more enterprises are opting for the cloud’s flexibility and agility rather than making upfront investments. Reduced operational costs, reduced hardware refresh costs, business agility, and adopted service model rather than building things from the ground up, and reduced operational risks are the key driving factors.

Cloud adoption, on the other hand, is not a simple process. If not adequately planned, migration of business legacy applications or rehosting infrastructure from the data center to the cloud can quickly go south. Even if they are successful, they may continue to operate in the same manner. To get the most out of the cloud, it’s critical to keep refining the infrastructure and adopting cloud design principles.

This Blog Post focuses on best practices that can aid enterprises in making a successful cloud migration.

Identify a Migration Strategy

For an active transfer of infrastructure and apps to the cloud, the most important component is a migration strategy. Preparation and a strong business case for the relocation are the first steps in a migration strategy. The 5 “R’s” given by Gartner can be used to sketch out a migration strategy.

Rehost – The “lift and shift” approach is also known as the “rehost” strategy. Typically, an enterprise will choose this technique if they need to quickly migrate their application to the cloud for commercial considerations. Another popular rationale for using the rehost technique is to give the team time to strengthen their skills.

Replatform — Another name for the Replatform technique is “lift, thinker, and shift.” The core architecture remains unchanged as part of this strategy. This is, however, a rapid modification that eliminates management and operations overhead and perhaps saves money. Moving databases to a managed database service provided by cloud providers or from one application server to another to save on license fees is an example of this method.

Repurchase – The “drop and shop” technique is another name for repurchase. In this instance, companies may opt to switch completely from one product to another in order to suit the needs of a business use case and take advantage of the most up-to-date features and capabilities. For instance, switching from one CMS platform to another or using a SaaS solution instead of developing your own.

Refactoring or Re-Architecting — This is a difficult technique to select, but it eventually proves to be one of the most profitable for businesses. When an organization’s existing application environment is unable to deliver features, scale, or performance, it is common for them to rework or re-architect their entire application to match the needs of a business use case, which can increase agility and business prospects.

Retire – Organizations choose this method during the discovery phase when they realize that 10%–20% of resources are underutilized and can be quickly discarded once the migration to the cloud is complete.

Discovery and Component Elimination

There is no rule that only one of the cloud migration strategies must be implemented. The discovery of the resources and applications running in the data center should be a top priority. Not only is the discovery phase limited in terms of finding resources, but it also limits the link or dependency between them. After you’ve completed the discovery, you’ll need to figure out what needs to be moved and what can be retired. Organizations should consider the component elimination phase of their RePlatforming strategy and identify architecture components that can be easily replaced by cloud-based services.

Organizations can, for example, employ a managed database service instead of running the master-slave MySQL database system. Organizations can also use the email service supplied by cloud providers instead of running their own SMTP server to deliver emails. This re-platform approach helps to reduce the actual cloud migration footprint and helps to experience the benefits and agility made available by the cloud providers.

Licensing and Migration Cost

One of the most important aspects of cloud migration is license management. Operating system licenses, application server licenses, and third-party tool licenses are among the license management components that apply to various regions of the environment. Organizations should check whether licenses may be migrated or converted to cloud-based licenses as part of their migration strategy. The licensing cost is included in the cloud provider instance cost for operating system licenses. Some cloud providers, on the other hand, provide the option of applying Windows licenses at the host level. On-premises and in the cloud, third-party solutions and companies are still figuring out the optimum model for license management. In a data center, many apps can share the same license because they are on the same hardware, but in the cloud, the application is scattered across multiple servers. Product firms are always working to improve license management as it gets complicated when the resources are added and removed based on the traffic load.

The next set of critical questions in the migration plan comprises deciding whether to use BYOL (bring your own license) or pay-per-use licenses from the cloud provider or marketplace. Each model has its own set of advantages, which should be determined as part of the migration strategy to avoid a major shift in the strategy. Finally, the cost of the migration tool should be carefully considered. Although the cloud provider offers its own set of services, any third-party costs should be factored in as well.

Network Management

Before beginning the migration, it’s a good idea to design the full cloud architecture and map the resources to their appropriate areas or subnets. The cloud allows you to create a virtual private cloud or network, as well as create subnets with the needed IP blocks, assign IP addresses to resources, and set up routing between them. In most cases, the legacy application components should have the same IP address for functionality continuity, as the components rely on the IP address for communication.

The resources are mapped to the same domain name for a seamless migration and switchover, and detailed communication is delivered to all stakeholders to minimize any confusion.

Team Technical Expertise

The success of an organization’s cloud migration journey is determined by the skill of its workforce. Whether in the cloud or in the data center, the team’s end goal remains the same: efficient resource management to keep applications up and running and meet business objectives.

It is, nevertheless, the voyage that is important. Because the cloud introduces abstraction and has different design principles than on-premises, it is critical to teach and develop this skill set across teams (operations, development, and design) so that they can swiftly adapt.

Training and developing this skill set takes time, so organizations may hire a new team with the necessary skills or hire a managed services provider with migration expertise who will have created a template and automation around the migration that can quickly address complexities and keep the plan on track.

Access Management

Enterprises have a centralized security access mechanism that allows them to grant access to persons across a server farm or application. They provide team members with functional role-based access. When moving to the cloud, access management is different than usual, and preparations should be made to ensure that teams have the proper and minimal privileges to complete their tasks. The cloud does offer the possibility to connect centralized access management with cloud services, ensuring that access concerns are avoided. In addition, as part of the migration process, access governance regulations should be implemented.


Start Small

It is always important to begin modest in order to ensure the success of the overall relocation process. Organizations should pick a small application, devise a migration strategy, and implement it. It assists them in identifying gaps and refining their master migration plan. This activity will also help technical workers become more familiar with cloud services, as well as transform stakeholders’ mindsets by helping them to see the benefits of cloud migration.

Identify Repeated Items and Automate Them

We can build infrastructure as code and deploy applications instantly without any downtime thanks to cloud automation. During the migration strategy, the same thought process might be applied. Organizations encounter repetitive patterns during the migration of many applications, which should be automated. It will reduce migration time, improve consistency, and disseminate an automated thought process across teams, allowing them to realize the true value of shifting to the cloud.

Monitoring and Governance

The environment should be thoroughly reviewed and monitored during the cloud migration or post-migration period. Because architecture components can change, it is not always the case that an application behaves the same way it did in the data center. The application, system, network, and audit logs, as well as the data provided by the monitoring dashboard, should be captured and thoroughly studied in order to perform a correlation between the various components and visualize and identify improvement areas so that better advantages may be realized. Looking at the resource use pattern and right sizing the servers to reduce the cost of the infrastructure is one easy example.
