What Is AWS Migration?

In simple terms, the AWS cloud migration proposal template includes the process of moving your digital assets, such as applications, data, and IT resources, from on-premises or physical systems or other cloud environments to the AWS platform.

The AWS migration process can be useful in the following instances:

  • Organizations concerned about data loss or downtime due to natural disasters, hardware failures or cyberattacks can leverage AWS disaster recovery solutions.
  • Companies looking to expand globally can easily deploy and scale their applications to new regions, enabling them to reach customers more efficiently and responsively.
  • Firms operating in regulated industries or requiring robust security measures can thus gain data protection, privacy, and compliance.
  • Companies looking to accelerate innovation and bring their products and services to market can take advantage of machine learning and serverless computing.

Embracing AWS can empower businesses to stay agile, innovative, and competitive in today’s rapidly evolving digital landscape.

Cloud Migration Definition

Cloud migration refers to the process of moving data, applications, and other business elements from an offline environment or another online platform to a cloud computing environment. The typical AWS migration planning involves transferring workloads, databases, storage, and other IT resources to cloud-based services and infrastructure.

A company with an AWS migration project plan is motivated by various factors, including scalability, cost-efficiency, flexibility, and better security. 

Cloud migration requires careful planning, assessment, and execution to ensure minimal disruption to business operations and maximum benefit from the transition. It may also involve re-architecting or refactoring applications to make them compatible with cloud environments and take full advantage of cloud-native functions.

Overall, cloud migration enables organizations to modernize their IT infrastructure, improve efficiency, innovation, and agility, and better respond to changing business needs and market dynamics.

Four Benefits of AWS Migration

Amazon Web Services (AWS) provide cloud computing resources as a service, liberating your company from allocating costly resources to tasks that don’t directly contribute to your income. This AWS migration planning and actualization allows you to focus on your business’s core goal instead of investing time, personnel, and money into IT-related activities. 

In this AWS cloud migration readiness guide, you will find out the four main benefits of AWS cloud migration, and they include the following:

  • Cost savings. Instead of spending thousands of dollars on installing, configuring, and managing on-premises servers, you can run your operating system and all enterprise applications on the AWS platform with no upfront cost. 
  • Data security. AWS’s data protection model is based on shared responsibility. While AWS provides a globally secure infrastructure, individual customers are responsible for data integrity, confidentiality, and availability in the cloud. 
  • Better elasticity. AWS’s elastic pay-as-you-go nature allows you to align your infrastructure closely with demand, ensuring both lean and agile IT operations. 
  • Flexibility. AWS offers flexibility to integrate different programming models, databases, operating systems, and architectures you’re familiar with. AWS products and services are compatible with nearly all existing coding languages, eliminating the need to learn new codes or worry about data loss during migration.

For proper AWS migration phases, you should involve security teams from the beginning and integrate cloud security solutions at multiple layers, including organizational policies and multi-region central networking. 

Top AWS Migration Strategies

The process of migrating applications to the cloud involves different strategies:

  • “Retire” is meant for applications slated for decommissioning or archiving. By retiring an application, you effectively shut down the servers associated with its stack.
  • “Retain” involves preserving applications within the source environment or deferring their migration. These applications are not currently marked for migration but may be considered for transferring at a later date.
  • “Rehost”, also known as “lift and shift”, involves transferring applications from their source environment to the AWS Cloud without modifying the application itself. For instance, an AWS cloud migration project plan example could involve migrating an application stack from an on-premises environment to the AWS Cloud.
  • “Relocate” can move a significant number of servers, which may include one or more applications, from an on-premises platform to its cloud counterpart. This strategy allows for the transfer of infrastructure or objects to a different virtual private cloud (VPC), AWS Region, or AWS account.
  • “Refactor” migrates an application to the cloud and overhauls its architecture to fully use cloud-native features. This transformation aims to improve agility, performance, and scalability.

The on-premise to AWS migration checklist is customized to the specific needs and goals of the organization and aims to reduce disruption while maximizing the benefits of cloud adoption.

Even though refactoring is a viable option, it is generally not recommended in an AWS migration planning roadmap for large transfers due to its complexity, as it involves modernizing applications during the process. 

Introduction to the 6 Steps of Cloud Migration

Each of the six AWS migration steps represents an important stage towards the successful adoption of cloud technologies. From AWS migration assessment and planning to post-migration optimization, these phases provide a structured framework to guide organizations through the complexities of transitioning to the cloud.

Cloud Migration Planning and Preparation 

During this stage, you get a comprehensive understanding of the advantages associated with transitioning to the cloud, while also establishing your business goals. Typically, the company meets with a team of experts to develop an AWS cloud migration plan template.

Deciding the Migration Approach 

Here, you review your entire IT portfolio, identify any interdependencies among workloads, and develop an AWS cloud migration approach that aligns with your business objectives.


During the design phase, an organization does an AWS migration assessment of its current network, data center, and application environment. This process generates a set of comprehensive AWS database migration service documentation outlining the network, application transferring, and implementation procedures.


During this step, data from the on-premises environment is transferred to the cloud, along with applications using various AWS migration strategies such as rehosting, re-platforming, and refactoring.

Testing and Validation

In a typical AWS migration checklist, applications, and data are migrated to the cloud, and sufficient testing is conducted to ensure that everything functions as expected and meets certain requirements such as performance, security, and compliance.


After migration, optimization efforts are made to improve performance, reduce costs, and make the best of available resources. These AWS Migration phases are a must-observe for every ideal AWS project.
