New Whitepapers on Cloud Migration: Migrating Your Existing Applications to the AWS Cloud

CloudmigrationDevelopers and architects looking to build new applications in the cloud can simply design the components, processes and workflow for their solution, employ the APIs of the cloud of their choice, and leverage the latest cloud-based best practices for design, development, testing and deployment. In choosing to deploy their solutions in a cloud-based infrastructure like Amazon Web Services (AWS), they can take immediate advantage of instant scalability and elasticity, isolated processes, reduced operational effort, on-demand provisioning and automation.

At the same time, many businesses are looking for better ways to migrate their existing applications to a cloud-based infrastructure so that they, too, can enjoy the same advantages seen with greenfield application development.

One of the key differentiators of AWS infrastructure services is its flexibility. It gives businesses the freedom of choice to choose the programming models, languages, operating systems and databases they are already using or familiar with. As a result, many organizations are moving existing applications to the cloud today.

In that regards, I am very excited to release our series of whitepapers on cloud migration.

Download Main Paper : Migrating your existing applications to the AWS cloud (PDF)

This whitepaper will help you build a migration strategy for your company. It discusses steps, techniques and methodologies for moving your existing enterprise applications to the AWS cloud. There are several strategies for migrating applications to new environments. In this paper, we share several such strategies that has helped enterprise companies to take advantage of the cloud.  We discuss a phase-driven step-by-step strategy for migrating applications to the cloud (see below).

To illustrate the step-by-step strategy, we provide three distinctly different scenarios listed in the table. Each scenario discusses the motivation for the migration, describes the before and after application architecture, details the migration process, and summarizes the technical benefits of migration:
