Migrating a monolithic application to AWS
A company is migrating its legacy on-premises applications to the cloud. The applications are monolithic and tightly coupled, making it challenging to scale and manage them efficiently. As a cloud architect, how would you leverage AWS compute services to modernize these applications and improve scalability, reliability, and manageability?

This question reads like it's from the Solution's Architect exam, but doesn't have the important details required to sufficiently answer it. I recommend reviewing the above white papers since we don't know anything about the structure. Usually you can break it down to services that authenticate users, scale with containers, store with databases and deliver with edge services. SQS is also a nice alternative to separate between areas. The biggest detail I'm looking at is the scaling and manageability of compute services. Containers would be ideal here, especially with something like Helm charts/Karpenter/Terraform(IaC).
Hi,
An approach to modernisation is dependent on the as-is workload complexity and the desired outcomes targeted usually supported by a business case. I would suggest you to take a look at this prescriptive guidance which outlines the strategy and approach to modernise applications using AWS services.
Hope this is helpful.
Thanks, Rama
Hi,
I believe that this whitepaper is exactly what you are looking for: https://docs.aws.amazon.com/pdfs/prescriptive-guidance/latest/modernization-decomposing-monoliths/modernization-decomposing-monoliths.pdf
Best,
