When planning and executing a migration to the AWS cloud, businesses should consider the following strategies and best practices:
The 6 R's of migration is a framework that outlines six different migration strategies:
Rehosting : Also known as "lift and shift," this strategy involves moving applications and data to the AWS cloud without making any changes. This is the quickest migration approach but may not fully leverage the benefits of the cloud.
Replatforming : This strategy involves making minor changes to applications, such as changing the operating system or database platform, to optimize them for the AWS cloud.
Repurchasing : This strategy involves moving from a legacy application to a cloud-native, SaaS-based application that is hosted on AWS.
Refactoring : This strategy involves re-architecting applications to take full advantage of the cloud's scalability, elasticity, and other benefits. This can be a more time-consuming approach but can yield significant long-term benefits.
Retiring : This strategy involves identifying and decommissioning applications that are no longer needed or can be replaced with more efficient cloud-based alternatives.
Retaining : This strategy involves keeping certain applications or components in their current environment, either because they are not suitable for the cloud or because the migration would not provide sufficient benefits.
A hybrid cloud migration approach involves maintaining some applications and infrastructure on-premises while moving others to the AWS cloud. This can be an effective strategy for businesses that want to leverage the benefits of the cloud while retaining control over certain mission-critical or sensitive applications and data.
When selecting a cloud migration service provider, consider the following factors:
Experience and Expertise : Choose a provider with a proven track record of successful AWS cloud migrations and a deep understanding of the AWS platform and its services.
Certifications and Partnerships : Look for providers with AWS certifications and partnerships, as these indicate a high level of expertise and commitment to the AWS ecosystem.
Customized Solutions : Select a provider that offers tailored cloud migration solutions based on your unique business needs and requirements.
Post-Migration Support : Ensure that your chosen provider offers ongoing support and optimization services after the migration is complete, helping you to maximize the benefits of the AWS cloud.
In addition to the factors mentioned above, consider the provider's pricing model, communication and collaboration capabilities, and customer testimonials and case studies.
Application migration services involve moving your applications from an on-premises environment to the AWS cloud. This can include rehosting, replatforming, or refactoring your applications to optimize them for the cloud.
When planning an application migration, consider the following factors:
