Web Browser Programming in Java - Using GWT and JsInterop

So in the year of 2019 web development is entirely occupied by JavaScript or derivatives like TypeScript? Well, not entirely… One small village of indomitable Open Source Java developers still holds out against the invaders with the help of Java to JavaScript transpiler GWT (http://www.gwtproject.org) and J2CL (https://github.com/google/j2cl)

Moving Host Cobol Batches and Monolith Webapps to Cloud and Microservices

Very interesting presentation in Amazon Event "From Mainframe to Microservices - Vanguard's Move to the Cloud". Following parts can be used as Migration Patterns:

Different ways of how to move from Mainframe to Microservices:
Re-hostReengineer RefactorRewriteBatch job migrationData analytics enablementData-driven augmentationRe-platform with Linux and JavaRepurchaseRetireCombination of all This presentation also shows the Cloud Data Architecture at Vanguard. Generally this is how we can build our own database for our micrsoservicew at the cloud and at the same time still use the data from DB2 mainframe on-premise as well. 
Advantages using this data architecture: Each microservice reads data from its own local database.DB2 mainframe database can still be used from other Host / Cobol batches.DB scalability Disadvantages: You cannot write to the database in case you have a network problem. There is an extension to this Cloud Data Architecture by using buffered write or asynch…

WikIT42 - Structure for IT Division and IT Products

Although the three different companies have completely different domains (marketing, payment and environmental services) the stucture of the division and products are quite the same.

Low Code == Low Quality?

Recently Manuel and I wrote an article about Low Code / No Code Platform at heise.de: http://bit.ly/LowCodeHeise. It is quite interesting to see the discussions. More than 400 discussion items. It seems that this topic is quite an important topic for developers. Most of them are against or don't trust Low Code / No Code Platform.
