Java Heap Space vs. Stack Memory: How Java Applications Allocate Memory By Angela Stringfellow Java applications need a certain amount of RAM on a computer to run. Each time an object or variable is declared, it needs more RAM. Simply designating enough memory to hold every value declared and run each method would lead to a bloated application. To keep application memory requirements lean, it is partitioned in ways that require less memory and allows the application to run more quickly. The Java Virtual Machine (JVM) divides memory between Java Heap Space and Java Stack Memory in a way that only uses memory that's needed. What Is Java Heap Space It is created by the Java Virtual Machine when it starts. The memory is used as long as the application is running. Java runtime uses it to allocate memory to objects and Java Runtime Environment (JRE) classes. When an object i... (more)

Serverless Architectures Are Here | @CloudExpo #FaaS #AI #DX #Serverless

Thanks to cloud computing, deploying our applications is much easier than it used to be. How we deploy our apps continues to evolve thanks to cloud hosting, Platform-as-a-Service (PaaS), and now Function-as-a-Service. What Is Function-as-a-Service (FaaS)? FaaS is the concept of serverless computing via serverless architectures. Software developers can leverage this to deploy an individual "function", action, or piece of business logic. They are expected... (more)

Integrating APM into Testing | @DevOpsSummit @Stackify #DevOps #APM #AI

Integrating APM into Your Testing Strategy By Erik Dietrich Does your team have a testing strategy?  In 2017, I have a hard time imagining that wouldn't at least have some strategy, however rudimentary.  Unlike a couple of decades ago, you hear less and less about people just changing code on the production server and hoping for the best. At the very least, you probably have a QA group or at least someone who serves in that role before shipping your software.  You write the code, do something to test it, and then ship it once the testers bless it (or at least notate "known issues...
