Application Modernization

for our October 7th webinar featuring Forrester - Total Economic Impact™ Study of OpenLegacy: Introducing Hub

NEW Forrester Total Economic Impact™ Study

We're signing up new partners excited about OpenLegacy's legacy integration. Read the news!

Watch our on-demand joint webinar with Google Apigee, From Core Systems to API Products: The Solution.

Make legacy code modernization work better

Code modernization makes the system more modular, supports modern architectures, and aligns with DevOps. There are six major modernization methods - rehost, rewrite, refactor, reengineer, replace, retire. All of these methods have a perceived problem - it takes time to achieve results. This prevents the delivery of new innovations and services quickly.

You can’t afford to wait years to complete a modernization project. With an API Factory approach, you can leverage your legacy systems while working on the modernization project - without sacrificing your digital innovations.

How OpenLegacy helps achieve modernization goals

Rehost

If Rehosting requires access to core assets, e.g. COBOL copybooks or similar language artifacts. OpenLegacy’s platform generates interfaces to core systems as easy to use digital assets.

Rewrite, Refactor, Reengineer

When rewriting applications companies need to parse the legacy system assets. Next, they need to write code and connect everything together. OpenLegacy’s platform automatically parses the legacy assets and generates digital assets.

Once rewritten you can replace the OpenLegacy microservices with your own and outside applications won’t have to change.

Replace

Similar need as for rewrite except the choices are based on selecting a 3rd party application and connecting it to the rest of the infrastructure.

Retire

When looking to retire functionality typically you need to decide when to deprecate it and sometimes even why. In doing so sometimes you get a request for the existing functionality exposed digitally until you remove it.

The benefits of the OpenLegacy approach

Value from day 1

Spending years on a migration project before seeing value is a challenge. With a phased migration approach, quickly generate consumable digital services. Converting to the new application as required.

Granular approach to conversion

Tight-Coupling is a challenge in migrating off of legacy applications. Build a modern decouple application by initially keeping access to the core system from the digital resource. Easily convert it with a modular approach later.

Composable Digital Services

Quickly build reusable digital services from multiple systems. Developers can combine multiple modernization approaches into a single service.

Iterative way to mature API contracts

The phased migration approach decouples this maturing process from the conversion process. Get the contracts to the consumers long before finishing the conversion and mature them in parallel with rewriting your applications.

Flexibility in tech-stacks usage

Technologies typically are replaced during the migration timeframe. Kubernetes became ubiquitous in less than 24 months. Having an automated API Factory approach for creating digital services enables quick tweaks to accommodate new technology.

Aligns to a central DevOps pipeline and process

Align all dev team processes of generating digital services to the same main pipeline. Keep the lights on, and support the business while converting in the background. This provides tremendous value in terms of cohesion, consistency, governance and alignment.
