Word has it that a freely available Community Edition of the CPM Toolkit will be released shortly! ETA - within the next couple of weeks. By all accounts, it is going to provide the CPM functionality as laid out in Quest Software’s series of whitepapers on the topic.

Exciting stuff! In the meantime, here is a two minute introductory video to the toolkit to whet you appetite. Enjoy.

Over the last week or so you will have seen a couple of blog entries from my colleagues on how we are implementing Continuous Performance Management in our existing CI process and how CI and Application Performance Management are drawing closer and closer.

It’s time to start putting some meat on the bones of Continuous Performance Management and introduce HelloCPM and show how CPM and be integrated into an existing Java module using ANT as it’s build mechanism. Our CPM implementation can work with ANT or Maven, but for the sake of this introduction, we will focus on ANT.

Following on from our last blog entry on Amazon’s Elastic Computing Cloud (EC2) platform, in this blog we are going to explore two of the remaining topics on our original five-point roadmap. So far we have covered:

Next up we want to tackle, probably the two most important topics when it comes to making EC2 a viable platform for commercial business:

  • Security
  • Integration

Well, today was the final day of this year’s TSSJS. It’s been a really busy few days, I have been looking forward to some downtime but first I need to get this final blog entry completed!

There were two sessions today that really caught my interest:

  • Cutting Edge Productivity with RIFE - Geert Bevin of Uwyn and Terracotta
  • A Fast Hop into Real Object Oriented (ROO) - Ben Alex of Interface 21

TheServerSide Java Symposium, Barcelona: Day 2

Published by

at June 29, 2007 in IT, Java, Performance, Spring and TSSJS. 0 Comments

This morning started with the interestingly titled Java Performance Myths: What Lurks Deep Inside a JVM, presented by Cliff Click. This sounds like the rejected title of a hammer horror movie and to be honest, in the context of Java conferences, the subject matter is about as old. Every Java conference I have been to over the last 5 years carrys a session like this; dismissing the myths that Java is a slow language compared to C++. Cliff did a good job of presenting the material, but I just didn’t take anything new away from it. However, I’ve been attending Java conferences for a number of years now, so I think, if the topic of JVM performance was new to you, you may walk away with a better insight into what is happening inside the JVM.

The TSSJS kicked off today in not so sunny Barcelona! I’ve been here since Saturday enjoying the sights and sounds of what must be one of the most beautiful cities in Europe. The weather so far has been fantastic but not so today; hence I don’t mind that much spending the day in sitting in conference rooms listening to wise and learned individuals instead of strolling through this magnificent city.

Amazon Web Services (EC2 & S3) - The Future of Data Centre Computing? Part 3

I am going to take a slightly different angle on the AWS/EC2 topic this month. In the last blog entry I focused on addressing specific Java Web Application related development challenges (Tomcat clustering, Terracotta etc). This month, I am going to look at how we can extend EC2 to be used in the real world by ‘normal’ users. I know, in this day and age, it is fairly difficult to classify normal users; but for me a normal user is someone who uses their PC, MAC or whatever, to browse the web, write some letters, check their email and other normal day stuff.

VM Tuning with Quest’s PerformaSure and the Java Hotspot VM Options

In this blog entry I am going to speak about a recent tuning exercise on an application running on the Java Hotspot VM 1.4.2. It’s great that developers are adopting and using the latest versions of the JVMs but there are still a hell of a lot of applications out in the wild running on older versions of the JVM.

The application in question is a CRM type application, serving about 200 concurrent users, increasing in bursts to 300+ users, processing approximately 4.5 million customer contacts per year. Do the math, and considering the application is running on a single JVM, the application is processing quite an amount of consistent load over the course of a working day.

Recently it was decided to determine the capacity of the current production application server. The rollout of another considerable application is imminent and the customer felt that it was prudent to determine whether or not the current infrastructure had sufficient capacity to run the new system.

Since my last blog entry on AWS, there has been a number of interesting developments. Firstly, I said before that there were no documented success stories on EC2; well now there are! This is a clear indication that the EC2 community is alive and kicking and that, finally, people are starting to find a purpose for EC2. Maybe the most interesting of these, from a business potential point of view, is gumiyo.com; an ‘end to end mobile commerce platform’, connecting buyers with sellers, either on the mobile, hand-held devices or on the web. Up to this point, most ventures into EC2 consisted of social networking or media sharing applications, so it is nice to see something that has a real dollar value being rolled out on EC2.
