Dallas Monson Articles, COBOL, Consulting, Development Technologies & Tools, DevOps, Java, Keyhole Creations, Modernization, Programming, 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

Spring Boot – The Right Boot For You!

Matt McCandless Articles, Development Technologies & Tools, Java, Spring, Spring Boot, Tutorial 1 Comment

Need a little spring in your step? Tired of all those heavy web servers and deploying WAR files? Well youโ€™re in luck.

Spring Boot takes an opinionated view of building production-ready Spring applications. Spring Boot favors convention over configuration and is designed to get you up and running as quickly as possible.

The aim of this blog is just to get you familiar with how to get Spring Boot going on your machine. It is going to be fairly straightforward and vanilla. The goal is to get you started…

Welcome back to this JHipster tutorial series! In part one we covered creating a monolithic application. In part two, we walked through creating a microservice application (which was a bit more complicated).

For those of you out there working to get things going with JHipster, there are some setup things and โ€œgotchasโ€ that Iโ€™d like to highlight. So this little blog is more of a helper for those of you who have decided to try JHipster out and play around with it. Thatโ€™s what weโ€™ll be discussing in this blog post with the hope that I can help you minimize the getting-up-to-speed curve…

Blood, Sweat, and Writing Automated Integration Tests for Failure Scenarios

Billy Korando Articles, DevOps, Java, Opinion, Programming, Spring, Tutorial 3 Comments

I introduce the process I went through to diagnose the bug and determine the correct integration test solution to fix it the right way. In doing so, I had to create a test that accurately reproduced the scenario my service was experiencing in PROD. I had to create a fix that took my test from failing to passing. And finally, I worked to increase confidence in the correctness of code for all future releases, which is only possible through automated testing.
