July 2014 Meeting - Java on Docker

This month, we want to explore Docker and its use in the Java enterprise application world. Docker (https://docker.io) is one of the fastest growing technologies in the 12 months. Written Go ;), Docker lets you bundle your application inside a computing unit called a container that can be distributed, thus lessening the traditional error-prone dance of application deployment.

RSVP: Go to https://tampajug-july2014.eventbrite.com to let us know you are planning on coming to learn about Docker.

Note: the meeting will be held next Tuesday, July 29th at the ValPak location.

Java on Docker

For our July 2014 meeting, speaker Vladimir Vivien will explore the use of Docker as a deployable container for Java application. Topics (for this presentation may) include:

Introduction to Docker
Creating a Docker Image
Docker Setup for Java
Demo
Tools and Providers

June 2014 Meeting - Mule, the Open Source ESB

For the Tampa Java User Group's June 2014 meeting, it will be all about Mule, Mulesoft's open source ESB. Are you responsible or maintaining brittle code in your enterprise? The sort of code that can ruin your entire day when you have to make a change to it because it will break everything it touches? Then, you owe it to yourself to attend this talk on Mule by Bob Damato of Valpak.

RSVP: Go to https://tampajug-june2014.eventbrite.com to let us know if you plan to attend this awesome meeting.
NOTE: the meeting will be Wed, June 25 2014, (not our usual Tuesday) at the ValPak headquarters in St Petersburg, FL.

Mule, an Open Source ESB
An Enterprise Service Bus (ESB) is fundamentally an architecture. It is a set of rules and principles for integrating numerous applications together over a bus-like infrastructure. ESB products enable users to build this type of architecture, but vary in the way that they do it and the capabilities that they offer.

The core concept of the ESB architecture is that you integrate different applications by putting a communication bus between them and then enable each application to talk to the bus. This decouples systems from each other, allowing them to communicate without dependency on or knowledge of other systems on the bus.

The concept of ESB was born out of the need to move away from point-to-point integration, which becomes brittle and hard to manage over time. Point-to-point integration results in custom integration code being spread among applications with no central way to monitor or troubleshoot. This is often referred to as "spaghetti code" and does not scale because it creates tight dependencies between applications.
Join us for our June 2014 meeting to learn about some high level concepts and use-cases for where Mule and the ESB architecture could play a role in your organization.

Biography

Bob Damato, Director of Software Engineering – Valpak

Bob has been a self-described computer geek since he fell in love with his first Commodore 64 at eight years old. He developed his first business software systems (email, accounting, and order management) in the early 90’s while working as a graphic artist for his family’s commercial printing business.

Bob joined Valpak in 1995 as a Graphic Artist but discovered the IT department and set his sights on becoming part of that team. His “official” IT career started in 1996 as Tech Support Specialist repairing desktop Macs and PCs, but his true passion remained in software development. During his time in Tech Support he studied C, C++, and Visual Basic, as well as Windows, Unix and Database Administration. His IT career progressed as he spent a year each as NT Admin, Unix Admin and finally Database Admin.

Then in 2000, he became Lead Software Developer for the Valpak.com team and he was finally able to pursue his passion. Bob spent a year in that role before becoming Valpak’s Internet Technology Manager where, over the next nine years, he architected and led the development of over 50 web applications and six revisions of Valpak.com. He was promoted to Software Development Manager in 2010 and was given responsibility for all of Valpak’s software development.

In 2011, he was promoted to Director of Software Engineering and he currently leads the Software Engineering and QA teams that build and maintain the systems that support Valpak’s sales and order process, digital products, mobile apps, GIS mapping solutions, content management, and delivery logistics.

May 2014 Meeting - From JEE to Cloud Foundry: A PaaS Journey

Have you ever wondered how you can get your JEE-based to benefit from PaaS services such as easy deployment, configurable request routing, and resource scaling? For the Tampa Java(VM) User Group meeting for May 2014, Joshua Davis (Pivotal) will discuss Cloud Foundry, the Open Source Platform as a Service (PaaS) that is power many commercial public and on-premise cloud offering. Join us to learn how you can take your current JEE-based app an migrate to the Cloud Foundry open PaaS.

RSVP - Go to https://tampajug-may2014.eventbrite.com to let us know if you will be joining us.

From JEE to Cloud Foundry:
A PaaS Journey

This session will go through the concept behind Platform As A Service (PAAS) and how Cloud Foundry works to make Java Development faster and more productive. We will walk through developing an application and show the differences and advantages to using Cloud Foundry over other approaches. In addition the session will show the pre-requisites for using Cloud Foundry, and the steps to convert a JEE application built with JMS into one that can be enabled on the cloud.

February 2014 - Scalable Enterprise Messaging with RabbitMQ

February 2014 Meeting

Hello, and get ready to attend our second meeting of 2014. The theme for our February 2014 meeting is around scalable, fast, and polyglot messaging using RabbitMQ, an open source enterprise-class messaging broker. For this event, we will have speaker Vladimir Vivien (Pivotal Software, Inc) to show how RabbitMQ can scale to meet both your messaging and your business requirements with little fuss. So come join us on Tuesday, February 25 at the KForce offices in beautiful Ybor to learn about RabbitMQ.

RSVP to gain access to the building at https://TampaJUG-Feb2014.eventbrite.com

NOTE: The meeting will be in Tampa this time at the KForce Offices in Ybor.

Scalable Enterprise Messaging with RabbitMQ

In many Java projects, messaging has traditionally been either an after thought or ignored all together . Let's face it, the current JMS API (and the brokers that support it) are from the early EJB era where fragility rather than agility was the driving factor. While JMS is the workhorse in numerous enterprises, it has several shortcomings that make it less than ideal for emerging polyglot and agile technological ecosystems.

This presentation is to provide a high-level introductory view of modern messaging using RabbitMQ, an open source messaging platform. We will explore RabbitMQ protocols, its language-neutral approach to messaging, and how it can scale to handle your enterprise messaging needs.

Topics

Understanding the AMQP Protocol

Introduction to RabbitMQ

Messaging with Java + RabbitMQ

RabbitMQ as a Polyglot Messaging Broker

Scaling RabbitMQ for the Enterprise
