Quick Guide: App Migration and Modernization with AWS Cloud Infrastructure

Blog: Indium Software - Big Data

As businesses embrace digital transformation, application leaders are looking for effective ways to modernize legacy systems to leverage accelerate growth, improve efficiencies, customer delight, and competitive advantage. However, often businesses tend to start with the oldest systems but according to a Gartner recommendation, modernization of complex, aging applications tends to should focus on valuable capabilities and understanding the risk-to-reward ratio.

Modernizing efforts should focus on the entire product life cycle, following a focused and deep evaluation of your application estate, and budgeting and planning the modernization work with provision for continuous modernization.

The Three-Step Process to App Modernization

According to Gartner, app modernization should be undertaken following a three-step evaluation process to determine the best approach, which is determined by the problem that needs to be solved.

  1. Encapsulating the application’s data and functions by leverage and extending its features to make them available as services via an API.
  2. Rehosting the application component to other infrastructure (physical, virtual, or cloud) with its code, features, or functions as is.
  3. Migrating the app to a new runtime platform with minimal changes to the code, and no changes to functions, code structure, or features.
  4. Refactoring, restructuring, and optimizing the existing code to improve its nonfunctional attributes and remove technical debt.
  5. Rearchitecting the code to migrate it to new application architecture to leverage better capabilities.
  6. Rebuilding the application component by redesigning or rewriting it from scratch as per the existing scope and specifications.
  7. Replacing the old application component completely to develop a new one based on new requirements and needs.

Migration and Modernization with AWS

One of the leading cloud infrastructure service providers, AWS or Amazon Web Services, allows you to plan the migration of your applications based on your business objectives and at your own pace instead of agreements or licensing. For instance, it allows lifting and shifting of applications, refactoring, or fully re-platforming them, based on your risk-to-reward ratio and value-based prioritization of the applications you want to modernize.

AWS enables businesses to reduce payback periods to 6 months and reduce the total cost of ownership (TCO) by 64%. The flexibility and ease of use along with AWS’s deep service offerings have pushed it ahead of the competition — to become the leader in the cloud infrastructure market and garner 32 percent in the first quarter of 2021, with revenues of around $39 billion. AWS helps businesses meet their goals of lowering costs, increasing efficiencies, and protecting existing investments.

In most organizations, migration and modernization will need rearchitecting, rebuilding, or replacing.

With AWS, migration, and modernization is a three-phase migration process that can accelerate the migration of several applications quickly and efficiently using an iterative process to make the processes repeatable and predictable. Apart from AWS’s migration tools, it also offers a third-party migration tooling ecosystem for automation and intelligent recommendations leveraging machine learning.

The three-phase process aligns with the Gartner recommended three steps and provides the necessary tools to implement them. Tools such as Migration Evaluator, Migration Hub, Cloud Economics Center, and Prescriptive Guidance:
