Microservices, Monoliths, and NoOps

Monolithic Applications A monolith application, in layman terms, is where entire functionality of the application is packaged together as a single unit or application. This unit could be JAR, WAR, EAR, or some other archive format, but its all integrated in a single unit. For example an online shopping website will typically consists of customer, product, catalog, checkout, and other features. Another example is of a movieplex. ...

Java Web App Architecture In Takes Framework

java-logo

I used to utilize Servlets, JSP, JAX-RS, Spring Framework, Play Framework, JSF with Facelets, and a bit of Spark Framework. All of these solutions, in my humble opinion, are very far from being object-oriented and elegant. They all are full of static methods, untestable data structures, and dirty hacks.

ChronicleMap – Java Architecture with Off Heap Memory

java-logo

My last post was written a couple of weeks ago and after some valid feedback I’d like to clarify a couple of points as a preface to this article. The main takeaway from ‘Creating millions of objects with Zero Garbage‘ should be that with Chronicle you are not ‘limited’ to using jvm allocated on-heap memory when writing a Java program. Maybe ...
