High-Availability Load Balancer (With Failover and Session Support) With HAProxy

HAProxy seems very promising as a production use software loadbalancer. The only drawback with this solution is that one still has to use some extra piece of middleware to terminate a ssl session (stunnel, apache).

I believe in not inventing the wheel;-) That's another incarnation of DRY ... So a good starting point for AMI images are the ones of Rightscale. Continue Reading…

Apache Webserver and Tomcat Virtual Hosts

Posted by Edmund Haselwanter on Aug 25, 2008
Tags: apache, cloud, tomcat

Problem description: You want to server multiple web applications with one Tomcat instance. The brute force variant is to just "rewrite" or ProxyPass the request from e.g. www.myhost.com to the local tomcat with localhost:8080/myhost. But this leads to context urls of ressources in the served html pages. You can either deploy you webapp in the ROOT context (but there is just ONE ROOT context, so this does not work). So let us use virtual hosts on both, the apache webserver and the tomcat servlet container. Continue Reading…

Automated Environment: Puppet, iClassify, and Capistrano

There is a new hype: cloud computing. Your web site traffic grows? Add a new application server. Want to increase availability? Add a new web server. Among others Amazon offers a whole bunch of infrastructure to support these needs. But it is not enough to fire up a server. The web server should include apache, the app server should include tomcat. The deployment should be aware of the new app server. This is where Puppet, iClassify, and Capistrano come into play. Puppet does the configuration management, installs your desired web and app server.

Searching through github ( http://github.com/search?q=puppet) I came across a very similar approach on howto bootstrap EC2 images with capistrano puppet and iclassify. ec2-cap is build on top of the Rightscale Amazon EC2 gem (http://rightaws.rubyforge.org/)
