Enabling devops through Tcat permissions

motif

In my previous post, I talked about what devops is and the need for devops tools around Tomcat. In this post, I want to go in depth around collaboration between devs and ops and how it applies to Tcat Server.

A key concept of the devops movement is that not only are there developers and operations, but there are also lots of people in between.

REST constraints: A benefit-focused discussion, part 1

motif

REST – the REpresentational State Transfer as defined in Roy Fielding’s thesis –  is not a protocol, a standard, an API, a technology or a product. You cannot buy it, you can’t download and install it and you don’t need to poke another hole in your firewall for it. Instead, REST lives at a level completely decoupled form any specific technology, protocol or product, because REST is merely an architectural style: A set of constraints and principles,

Re-use: Accomplished! Configuration Patterns Catalog for Mule

motif

If you follow this blog or what’s happening in Mule 3, you’ve heard about the newly introduced configuration mechanism based on patterns. In the coming releases of Mule, we will keep adding new patterns based on users feedback and requests.

But this doesn’t mean your experience with configuration patterns will be limited to the ones that come with Mule distributions: we have made it easy for you to create your own patterns and,

You wouldn’t necessarily be very excited about reliable, graceful app server restarts — unless you go to restart your server and it doesn’t restart, or unless the restart script corrupted your webapp data. There are times when a reasonably fast, fully reliable restart is a very important feature. Some examples:

  • You found that your webapp has a new memory leak, and you just fixed it in development, just finished testing it, and you’re about to deploy the fixed version.

Devops and the role of Tcat Server

I’m pretty sure that if Dante was in IT, there would be at least one stage of hell devoted to getting developers and operations to work together well.  Horror stories abound. One of my favorite recent ones was about a company where the operations team wouldn’t let the developers surface any UI that they could access to manage their applications. The developers decided that they could get around this by building an API and then having a UI locally that they could use which was not in the realm of the operations team.

The Mule IDE 2.2.1 release that went out today contains a big productivity improvement: a hot deployment builder. It allows you to deploy your project to a running Mule 3 instance automatically. Read all about hot deployment in Mule 3 in the user guide.

The easiest way to get started with the hot deployment builder is to create a new Mule project. It will have the builder attached automatically.

Walk this Way: Building AJAX apps with Mule

There are some cool new features in Mule 3 for building AJAX applications. I figured I’d take you through a tour of the GPS Walker, an small example that demonstrates how to use AJAX to communicate from a Mule Service to the browser. This example uses other new features in Mule 3 including automatic JSON bindings, the @Schedule annotation and Flow.

Flow in Action: Simple Orchestrations Pwned!

Three months ago, I’ve introduced the newly created Erlang Transport for Mule 3 in this blog. To illustrate a usage scenario for this transport, which allows fast and seamless bi-directional communications between the JVM and the Erlang worlds, I presented an example where Mule was exposing a JSON over HTTP service for provisioning users in RabbitMQ.

At that time, the new configuration mechanism named Flow was not fully baked so I implemented the example “

Code Camp continues to grow by leaps and bounds each year. For those not familiar with Code Camp, it’s an all volunteer run conference at Foothill College each October and is on version 5.0. It lasts the whole weekend and this year over 3000 people registered and over 1900 ended up spending their weekend attending technical sessions ranging from How to Teach Programming to Kids to HTML5 Crash Course.

Implementing Kanban for Sustaining Engineering

motif

I’ve been working at MuleSoft on the Sustaining Engineering team for a few months. In this time I watched how things work and find out what type of challenges we deal everyday have and how we solved them. I watched a great team working long hours to solve customers problems as fast as possible. Our primary goal is to enable our customers to meet their deadlines, and remove any problem they might have with MuleSoft’s products in the process.
