1) Court.fm : Very Large Scale Network Infrastructure on Amazon Cloud Computing
One of the Court Record Solution from Australia's company. All I did is, setup a whole network infrastructure in Amazon Cloud Computing Platform which includes Windows Server 2008, Microsoft Streaming Media Server, Microsoft Sql Server 2008 with Database Mirroring with witness Server, IIS 7, WCF Services. Also set up a Security Group (firewall) to secure the network unauthorized access.
This was accompanied by setting up cloud watch services of amazon, based on different matrics, to monitor server and email alters. I have also setup Amazon Load Balancer for Web server (IIS7 and Microsoft Streaming Media Server ) for High Availability . And set up Amazon AutoScalling to Add or delete the instances based on needs. Currently there are 30 + instances which I manage on Amazon EC2. I am maintaining all the instances on daily basis such as backups , Monitoring , Installation & Configuration of different Services based on requirement.

4) Postfix mail server setup
I configured a mail server based on postfix. It was on CentOS and the additional package. I installed on the server was squirrel mail and also configured SMTP authentication.
5) Zimbra mail server setup
Zimbra mail server was setup on the Virtual Server using openVZ. A new template of openVZ is created which includes Zimbra installation which helps to reduce the installation time when new Virtual server will be created using that particular template.
