Adventures In Modernization: Strategy + Example Converting COBOL To Java

Dallas Monson Consulting, Java, Keyhole Creations, Programming, Technology Snapshot, Tutorial Leave a Comment

We have consultants who specialize in moving old to new, renovating dilapidated code bases, and designing brighter futures for enterprises who have been vendor-locked for most of their existence. We have come across some repeated patterns and strategies for how to approach modernization of legacy systems. In this blog, we will cover a strategy that is very popular right now, Re-Platforming.

The basic flow of this post will be:

Introduction to Modernization
High-level definition of the Re-Platforming Strategy for Modernization
Sample of Re-Platforming using Keyhole Syntax Tree Transformer, COBOL –> Java
Additional thoughts on the value/risk of this strategy

Let’s get started…



Getting Started With JHipster, Part 2

In part two of this series, we create a microservice architecture using JHipster’s available options for doing so. There is quite a bit more work to do with this approach as compared with the monolithic approach. But, in the end, it pays off. You will see the benefits and flexibility in decoupling our different layers of our architecture. Each layer will not be dependent upon another to run. Let’s get started…

Service Fabric is a massively progressive step for Microsoft. At the core, it is a distributed systems platform used to build scalable and reliable applications. But it gives the benefits of containerizing deployable bits, in addition to having Microservices best practices built-in. In this article, we will see how to quickly get up and running with Service Fabric, as well as why you …
