Hey Java Developers, I've been meaning to talk to you about something. We've been working together a while now, and I feel like you might not always give Production the respect it deserves. You don't always invite it to your requirements meetings, or work with it much during development. Sometimes it feels like you just hand Production your code and move on to other things! I'm setting up a meeting next week (April 11) to see if we can improve your working relationship. Here's a rough agenda. I'll bring some background on these things, and I hope I can get some good conversation started and improve your relationship: Service Discovery Configuration Secrets Health Logging Monitoring Telemetry Capacity Please go to Meetup and sign up so we will have a count for the food.

Spring 5 is almost here! One of the most exciting introductions in this release is support for reactive programming, building on Pivotal's Project Reactor to support message-driven, elastic, resilient, and responsive services. Spring 5 integrates an MVC-like component model adapted to support reactive processing and a new type of web endpoint, functional reactive endpoints. In this talk, we'll dive into the net-new Netty-based web runtime and see how to integrate it with existing Spring-stack technologies, learn how to leverage powerful new testing mechanisms to make code better and life easier, and tie it all together with a live coding demo. If there's more to your life than CRUD, you need to be there! * Due to the speaker's flight arrival being too close to our normal meeting time, we have chosen to delay the meeting by one (1) hour. Please note that the new start time is 12:30 pm. * Speaker Bio Mark Heckler...

February meeting is cancelled. We apologize for the inconvenience, but we were unable to obtain a speaker for this month. Be watching for details about the March 14, 2017 meeting. Happy Valentines Day!!!!

gRPC is a high performance, open source, general RPC framework that puts mobile and HTTP/2 first. gRPC is based on many years of Google's experience in building distributed systems - it is designed to be low latency, bandwidth and CPU efficient, to create massively distributed systems that span data centers, as well as power mobile apps, real-time communications, IoT devices and APIs. It's also interoperable between multiple languages. But beyond that fact that it's more efficient than REST, we'll look into how to use gRPC's streaming API, where you can establish server-side streaming, client-side streaming, and bidirectional streaming! This allows developers to build sophisticated real-time applications with ease. In addition to learning about gRPC and HTTP/2 concepts with code and demonstrations, we'll also deep dive into integration with existing build systems such as Maven and Gradle, but also frameworks such as Spring Boot and RxJava. Writing/using a Spring Boot starter to run gRPC server Configuring projects to generate gRPC stub code Integrating w/RxJava's observable sequences, which matches very well with gRPC's Stream Observable constructs Speaker Bio: Ray Tsang is a Developer Advocate for the Google Cloud Platform. Ray had extensive hands on cross-industry enterprise systems integration delivery and management experiences during his time at Accenture, managed full stack application development, DevOps, and ITOps. Ray specialized in middleware, big data, and PaaS products during his time at Red Hat while contributing to open source projects, such as Infinispan. Aside from technology, Ray enjoys traveling and adventures. Please go to Meetup and sign up so we will have a count for the food.

Next month (January 10th, to be exact), we will have Google Developer Advocate Ray Tsang ( https://twitter.com/saturnism) in town to talk about gRPC.footnote:[ The topic hasn't been nailed down yet. It should be either gRPC or Kubernetes. We're still discussing. :)] I saw a brief demo at JavaOne and it was awesome. This is a great opportunity for the Oklahoma City tech community, so we want to get the word out early, and, while the invitation is always implicit, we're trying to make sure other tech groups are aware that they, too, are invited. Another exciting change for the new year is that we now have, thanks to Techlahoma, our own Meetup group: https://www.meetup.com/okcjug/. We'll be using this group for meeting announcements, reservations, etc. We'll be basing our food order off of the registration numbers, so it's really important that you all create an account and RSVP for each meeting. There are no plans to deny food to those who didn't RSVP, of course, but getting accurate numbers ahead of time will help make sure we order the right amount of food. I think that's it for this year. Mark your calendar for January 10th. Go create a Meetup account. Watch for the meeting notice from Meetup and RSVP if you're coming. And have a very merry Christmas and and a happy new year!.

December meeting is cancelled. We apologize for the inconvenience but we were unable to obtain a speaker for this month. Be watching for details about the January 10, 2017 meeting. Merry Christmas and a Happy New Year.

NEW LOCATION Those of us involved with software systems have probably been hearing and reading about microservice architecture more and more. We'll explore why that is, what benefits this approach offers, and how to go about designing and building systems this way. We'll touch on promise theory, service discovery, handling failure, and disposable software. This talk is meant for humans who work together to try to get computers to do useful things. That includes java developers. Speaker Bio Ryan Hoegg We thank Techlahoma for generously providing the food and drink, and to StarSpace46 for providing the facility.

Elasticsearch is an open source, distributed, full-text search engine, built for speed. It offers solutions of scalability of big data search and it is accessible through API . In the recent time due to rapid growth of technologies, software development and its unprecedented utilization, search engine has become a paramount resource. During my presentation, we will see the basic concept of Elasticsearch,why should we care about it and how does it serve a mind-boggling performance. At the end, we will see a few live examples of some the common use cases.

The topic of Infrastructure as Code (IAC) keeps cropping up in the world of Continuous Delivery and Continuous Integration but the topic can seem a bit abstract. But what if it's compared with something everyone is familiar with, like board games? Dip your toes into the basics of automated deployment and Infrastructure as Code through some fun board game analogies. Learn about the benefits, challenges and tooling of IAC. Speaker Bio Tamara Bartlett is a software developer and consultant currently working for ThoughtWorks. After graduating with a degree in Computer Engineering and a brief stint at Boeing doing software for satellites, she now is interested in DevOps, back-end software development, and ways to make software teams work harder, better, faster, stronger. In her free time, she runs, drinks excessive amounts of coffee, skydives, and attempts to do yoga. In the near future, she's looking forward to presenting this talk at Grace Hopper Conference (for women in computer science) and attending HashiConf to learn more about Infrastructure as Code. We thank Techlahoma for generously providing the materials for the meeting, including the projector, pizza, chairs and to ProtoTekOKC for providing the cool environment. * We are meeting at ProtoTek again this month as the new location is still not ready. *

We've all come across many buzz words, new hyped techniques, and “The next big thing� in our reading. For the last few years I 've been seeing a lot about CQRS, Domain Driven Development, and Event Sourcing and thought it was time to find out what all the hype was about. In this talk we will discuss the Pattern of event sourcing and CQRS and what some of the advantages/disadvantages are when implementing this pattern. We will also do a high level code walk through using Java with the Axon Framework to implement this pattern in a microservice. Speaker Bio Justin Strittmatter, Senior Software Engineer, MBO Partners We thank Techlahoma for generously providing the materials for the meeting, including the projector, pizza, chairs and to ProtoTekOKC for providing the cool environment. * We are meeting at Techlohoma again this month as the new location does not have A/C yet. Stay tuned for details on the new location. *
