JVM Cloud Platforms

Tonight kicked off with the usual high quality lightening talks that I have come to expect form the London Java Community.

The two main presenters spoke individually about the cloud solutions that their individual companies offered. I know little to nothing about cloud computing. The emphasis was centred around Platform As A Service (PaaS). It appears that most of the major players (Amazon, google, etc) do not provide a private PaaS for testing and development. I find this astounding, despite the fact that I have worked with at least one major vendor who makes it very expensive to have a development environment, but at least it was still possible.

The stronger of the two systems described seemed to be the offering from SpringSource. Peter Ledbrook (Grails Advocate and ACCU Mentored Developers mentor) is a very interesting speaker. He has clearly been bitten by live demos not working in presentations before and, alas, he was bitten again tonight. Although, the previous speaker also had a problem with his live demo.

The more I hear about cloud computing, the more interested I get. With the two offerings this evening there is the opportunity to try it for free to get a real feel for it. However, I just don’t have a sufficient interest yet or a cloud suitable application to make it worth the while. Maybe my next contract.

  1. Cloud can be a nebulous term.

    Srsly!

    So when you say, "The more I hear about cloud computing, the more interested I get", what sort of cloud computing are you talking about?

    Is it structly PaaS?

  2. I like the idea of publishing an application to the cloud. I haven't really got beyond that at the moment. So yes, for the time being PasS.

Write Your Own Load Balancer: A worked Example

I was out walking with a techie friend of mine I’d not seen for a while and he asked me if I’d written anything recently. I hadn’t, other than an article on data sharing a few months before and I realised I was missing it. Well, not the writing itself, but the end result. In the last few weeks, another friend of mine, John Cricket , has been setting weekly code challenges via linkedin and his new website, https://codingchallenges.fyi/ . They were all quite interesting, but one in particular on writing load balancers appealed, so I thought I’d kill two birds with one stone and write up a worked example. You’ll find my worked example below. The challenge itself is italics and voice is that of John Crickets. The Coding Challenge https://codingchallenges.fyi/challenges/challenge-load-balancer/ Write Your Own Load Balancer This challenge is to build your own application layer load balancer. A load balancer sits in front of a group of servers and routes client requests across all of the serv

Bloodstock 2009

This year was one of the best Bloodstock s ever, which surprised me as the line up didn't look too strong. I haven't come away with a list of bands I want to buy all the albums of, but I did enjoy a lot of the performances. Insomnium[6] sound a lot like Swallow the Sun and Paradise Lost. They put on a very good show. I find a lot of old thrash bands quite boring, but Sodom[5] were quite good. They could have done with a second guitarist and the bass broke in the first song and it seemed to take ages to get it fixed. Saxon[8] gave us some some classic traditional heavy metal. Solid, as expected. The best bit was, following the guitarist standing on a monitor, Biff Bifford ripped off the sign saying "DO NOT STAND" and showed it to the audience. Once their sound was sorted, Arch Enemy[10] stole the show. They turned out not only to be the best band of the day, but of the festival, but then that's what you'd expect from Arch Enemy. Carcass[4] were very disappoin

Catalina-Ant for Tomcat 7

I recently upgraded from Tomcat 6 to Tomcat 7 and all of my Ant deployment scripts stopped working. I eventually worked out why and made the necessary changes, but there doesn’t seem to be a complete description of how to use Catalina-Ant for Tomcat 7 on the web so I thought I'd write one. To start with, make sure Tomcat manager is configured for use by Catalina-Ant. Make sure that manager-script is included in the roles for one of the users in TOMCAT_HOME/conf/tomcat-users.xml . For example: <tomcat-users> <user name="admin" password="s3cr£t" roles="manager-gui, manager-script "/> </tomcat-users> Catalina-Ant for Tomcat 6 was encapsulated within a single JAR file. Catalina-Ant for Tomcat 7 requires four JAR files. One from TOMCAT_HOME/bin : tomcat-juli.jar and three from TOMCAT_HOME/lib: catalina-ant.jar tomcat-coyote.jar tomcat-util.jar There are at least three ways of making the JARs available to Ant: Copy the JARs into th
