I had the privilege of being invited to speak at EclipseCon France (June 13th & 14th) about Microprofile, microservices, and JWT. The conference took place in Toulouse and being from France I have been there a couple of times, but never took the time to enjoy it. The architecture is beautiful, the city clean, and the people nice. Don’t know if it was because it was the beginning of summer or not, but I found the city very active and alive in the evenings. The conference was held at the convention center downtown. The venue is large and well organized. There were…

My road trip from Coimbra, Portugal to Madrid, Spain, where I spoke to the Madrid JUG about REST security, was beautiful, but full of wrong turns, some potholes, and flash thunderstorms. It reminded me of my adventure in learning and coming to understand REST security. There are so many security specifications that it's easy to get turned around and to encounter new technical concepts. The "Deconstructing REST Security" talk, originally created by David Blevins, is like a clear roadmap to navigate the potholes and thunderstorms of REST security. It makes navigating the difficulties far simpler, providing both context and a clear route to…

The inaugural Javeros de Colombia conference was held in the city of Cali Colombia on May 19th. The Javeros de Colombia is designed to provide a space for Latin American Java User Groups, education, public and private sectors to gather together and discuss the latest Java related technologies and trends like: Microservices, Cloud, Jakarta EE, Microprofile, Security, and DevOps. The conference was organized by three Columbian JUGs from the cities: Cali @CLOJUG , Medellin @MedellinJug, and Barranquilla @JUGBAQ . Together these JUGs created an outstanding gathering with content and with speakers from all over Latin America that included Community Leaders, Open Source Advocates, Java Champions, Oracle Aces and…

In the world of Microservices, knowing how your server, application and container are doing is crucial for success. In production, every system administrator wants to be able to proactively check the container memory, the disk, the network, and the JVM. They need to know how many times a service is being called, how long this service took to execute, and several other metrics that help to manage services before they become unavailable. The MicroProfile Metrics is a specification that provides a standard way for application servers to expose metrics and, also, an API for developers to build their own application metrics. This article will…

The need With the rise of microservices or large scale distributed systems and communicating through HTTP and NoSql databases, we also see the rise of eventual consistency. The focus on reliability or the perfect operation at all times had to shift to resilience; the ability of an application to recover from certain types of failure and yet remain functional. All-or-nothing and reliable transactions were paramount, data had to be safely stored above all, sacrificing the user experience and cost. The objects on those transactions could also be very complex, frequently using multiple tables and even different databases. Typically, if a…

This July the Eclipse MicroProfile put in motion efforts to file our first JSR, now known as JSR-382 Configuration API 1.0 submitted by the Eclipse Foundation. While there are several fantastic technical merits around JSR-382 Configuration API 1.0, from an industry perspective, this JSR is the very zeitgeist of where we are at and where we are headed. Like Kevin Bacon, almost everyone and everything is 6 degrees of separation from the Configuration JSR and after this JSR, nothing will ever be the same again. Why File a JSR at all? Let's call out the elephant in the room. Some…

Today we are announcing a new collaboration called the MicroProfile. Together with Red Hat, IBM, Payara, the LJC and all who will join us, we aim to merge innovation and standardization into Enterprise Java with Microservices focus. Microservices in Enterprise Java If you look at all the servers in the Enterprise Java space, particularly Java EE implementations, you see a trend: lighter is better. From the day TomEE was announced in 2011 it was a 30MB distro, booted in a second, ran with default 64MB JVM heap and passed the Java EE 6 Web Profile TCK on hundreds of t1.micro…
