Architecture

[paulstadler]

Is there any architectures for deploying applications on tcServer? Any documentation or approaches would be helpful especially with clustering and load balancing, deployment etc.

tc Server is built on Apache Tomcat so the same architectures that work with Tomcat will work with tc Server. The right architecture will depend on what you are trying to achieve but as a rough guide:
- load balancing is usually achieved using httpd or a hardware LB
- if using httpd and you are familiar with mod_jk use that
- if using httpd and you are not familiar with mod_jk use mod_proxy_http
- enable sticky sessions
- consider if the benefit of clustering is worth the additional configuration complexity and processing overhead - often it isn't
- it is often worth disabling connection pooling between http and tc Server

For deployment with tc Server I'd always use AMS. It provides simple deployment to multiple tc Server instances. If you need something more flexible then take a look at the AMS command-line client.

Hi Mark

Thanks for the info. I am in the process of migration applications to tcServer from WebSphere.

Are there any best practices that one can follow for the migration? Also is it a good idea to have 1 app per container? What is the general approach?
