It’s a well-known fact that business requirements and underlying software systems change at different speeds. Over time, most legacy systems become misaligned. Business and IT have to compensate with workarounds, often at a price of IT agility and increased process overhead. Legacy Modernization is a low-risk approach that enables a continuous realignment of the applications with business outcomes, while preserving the investments into intellectual property accumulated over the years. The key recipes are reuse, self-service, governance and security.
I would like to invite you to watch the recording of our latest webinar: From Mainframe to Microservices where we showcase how APIs can power modernization initiatives in your organization. Mike O’Meara, Dmitriy Kuznetsov, together with Matt Serna at Mulesoft, discussed how an API-led strategy and Anypoint platform help accelerate Legacy Modernization initiatives. Dmitriy demonstrated typical integration use cases for the IBM i platform using Anypoint, AS/400 connector and Web Transaction Framework.
The webinar was held on Tuesday February 7, 2017 at 8 AM PST / 11 AM EST.
Modern enterprise architectures shift from all-encompassing ERPs to a network of smaller components that address specific business capabilities and communicate via common integration channels such as APIs. In some cases migrating to new system or best of breed may work. For most companies, however, the complete replacement is a risky and expensive proposition. Most successful modernization initiatives use a hybrid approach. Core line of business ERP systems are revitalized while some non-differentiating components that run industry standard processes may be replaced with purpose built applications or services.
The ERP components typically communicate with each other via shared database, resulting in a complex web of bi-directional real time integrations. When migrating a part of such system, these implicit inter-process communications must now be brought to light. The success of the project often depends on the speed of implementing these use cases. Comprehensive integration platforms such as Mulesoft Anypoint help delivering integrations at scale.
In this post I will show how to implement a real time external API call from IBM i (AS400) application using Mulesoft Anypoint, AS/400 connector, and Web Transaction Framework.
