I have been a cloud and system architect for many clients with a operation experience of more than 17 years. I have designed, developed and maintained very large scaling, load-balanced and redundant infrastructure for many clients.

Most of the infrastructure I have designed are

• fully automated (chef/puppet and deployment via various code deployment tools integrated with git or subversion)
• auto-scale (on demand scaling)
• auto-heal and auto curate
• fully load-balanced in required cases geo-distributed
• Monitored with custom performance plugins
• Customized Security Audit

This infrastructure architecture and deployments were in

=> different environments
* Dedicated servers
* Virtualized Environment (Xen, KVM, VMware, OpenVZ, Virtualbox, Hyper-V and others)
* Cloud:
-Public cloud: Amazon, Rackspace, GoGrid, CloudSigma, ElasticHost, CloudCentral, Joyent, Softlayer, and others
-Private Cloud:
= OpenSource: OpenStack, CloudStack, OpenNebula, OpenQRM, Eucalyptus, and others
= Proprietory: VMWare, Citrix Xen, 3tera, and others

=> Different Business Verticals
* Ecommerce
* Social Application
* Big Data Analysis and Analytics
* Media (audio and video)
* Realtime Gaming
* Hosting industry
* Finance

=> Different Applications/stacks/services
Almost all known application stacks, services and deployments in the Linux and Windows World has been deployed by me. In many cases I have efficiently clustered them and constructed scalable architectures for them.

Most of these infrastructure architecture are for high volume traffic web application or for massive computing requirements.
