If you don’t know about Spring Insight Developer, this post may save you tons of time and potentially headache.
Imagine that you need to update some code behind a button, but you didn’t write the code. What if you could press the to-be-coded button and then see what code was invoked (including methods and arguments), the SQL invoked, and the time it took to execute?
This is what Spring Insight Developer allows you to do, and more.
It’s also free, and it uses AspectJ and AOP to load-time weave your application, you do not have to make any changes to your application code to use it.
Let’s take a look at a simple example of tracing your app, viewing the details, and seeing the code in action.
Earlier this week, we announced the general availability of a major upgrade to vFabric Application Performance Manager (APM). This release started one year ago, after we released the first version of the product to market. When we started work on this release, we knew we would need to invest heavily in scalability. APM is designed to help simplify monitoring and management for highly dynamic, large web applications living in the cloud. To succeed, we needed to make sure our product could scale gracefully with our customers. So, we set out with a challenging goal to increase the capacity of APM by a factor of 5.
Transforming a complex product such as APM into a more scalable architecture is not an easy task, let alone doing so in a single release. For this reason we’ve started by modifying the architecture in steps, starting with local improvements inside our virtual appliance, (available in the APM 5.0 release) and moving towards a horizontal scale solution in future releases.

This week we are excited to have a guest post on vFabric RabbitMQ from Mike Hadlow, enterprise Microsoft.NET developer and architect with 15below.com. Mike covers:
Their Architecture Before RabbitMQ
Why they went with RabbitMQ
Their Infrastructure and Development Environment
How RabbitMQ fits in their Software Architecture
In this post, I want to share our experiences of using RabbitMQ at 15below.
15below is based in Brighton, UK. We provide messaging and integration services for the travel industry. Our clients include Ryan Air, Qantas, JetBlue, Thomas Cook, and around 30 other airline and rail customers. 15below sends hundreds of millions of transactional notifications every year to its customer’s passengers over a wide range of channels including email, SMS, push, and voice.
RabbitMQ has helped us to significantly simplify and stabilise our software. It’s one of those solutions that you install, configure, and then really don’t have to worry about. In over a year of production, we’ve found it to be extremely stable without a single production issue. Continue reading →
We are pleased to announce version 3.0 of RabbitMQ!
This release introduces dynamic, policy-based control of mirroring and federation, improves the user friendliness of clustering, adds support for per-message TTL, introduces plugins for web-STOMP and MQTT, and adds many smaller new features and bug fixes.
Binary and source distributions of the new release can be found on the download page
Recently, we had the opportunity to speak with architect Brett Cameron about vFabric RabbitMQ. A popular speaker, Brett is well known for his effort to port Erlang and RabbitMQ over to the “legacy” OpenVMS operating system platform (now owned by HP). With over 19 years in the software industry, Brett specializes in systems integration and large, distributed systems. Of course, he has spent a lot of time with OpenVMS – an OS with one of the more interesting histories in the software industry.
When we started chatting with Brett, he had recently discussed the concept of the Polyglot Rabbit with Alexis Richardson and written a great article titled, “The Polyglot Rabbit: Examples of Multi-Protocol Queues in RabbitMQ.” According to Brett, the main goal of this article is about the fact that you can publish messages into this environment via one protocol and consume via one or more other protocols (simultaneously if you want). “It’s a brilliant and a very powerful capability.” Brett felt that this capability was possibly not being promoted enough, and hopefully the article will go some way towards fixing this.
If you haven’t heard of HighLoad++, the conference is pretty special since it focuses only on high traffic websites (mostly from Russia). The main point of the conference is to talk about new architectures and approaches for highly complex systems and covers things like:
If you haven’t heard of ROBLOX, they allow users develop their own games – creating players, 3D worlds, and objects from first-person shooters to genres like military and sci-fi. They are able to share these games with others, and, of course, play them. The ROBLOX application also has a built in advertising system, social network, and virtual economy with currencies. According to their website, they generate:
Over one billion page views, 29 million in-game hours, and 10 million unique visitors per month.
Players created 5.4 million games and spent over 250 million hours of game-play in 2011
vFabric Suite 5.2 has been released and is now available for VMware customers to download and deploy. Considered a minor release, this update fulfills VMware’s desire to update the 13 different application components that comprise the suite every six months. The improvements across the products for this version focus on improving standardization and consistency across products, an important maintenance effort as several of the products are relatively new to the vFabric product portfolio. Customers will universally benefit from standardization across products on five fronts:
Over 37,000 VMs have been started in Hands on Labs. Hands on Labs run in Hall 6 through Thursday. vFabric labs include Application Director, Data Director, CloudFoundry, SQLFire and scaling with vFabric.
As noted in the Field Report from Day 2, we greatly appreciate the opportunity to listen and learn from our VMworld Europe customers, prospects, and partners! VMworld this year has not dissapointed. We’ve met with hundreds of partners, thousands of customers and spun up tens of thousands of virtual machines in our hands on labs. Over 37,000 in fact at the start of Wednesday, with two more full days to go! An impressive event all around.
Not surprisingly after the keynote yesterday, customer discussions have continued on Application Director, with many stating explicitly that they are going to use this as the cornerstone opportunity to build out a self-service infrastructure, just like VMware’s own IT did.
Beyond that, a few other key themes have emerged:
Significant vFabric Interest from VMware Partners
Monday was a partner day, and there is a lot of interest in vFabric from partners. They are looking to VMware to learn and improve how they are building apps for their customers in cloud environments. For one of our presentations on Monday, we had a packed house with over 100 people in the audience. Continue reading →
At VMworld in San Francisco, several partners shared success stories at the vFabric partner panel. As moderator for this session, I worked extensively with the three vFabric Partners prior to the event and uncovered a common theme – these experts are top notch at what they do and enjoy doing it. Each Partner had a unique vFabric story about successful implementations. Partners on the panel included Nancy Turbe with EMC consulting, Jeff Reed with Logicalis and Juan Garcia from Williams and Garcia. Their stories covered:
