In this example we've taken a company with a requirement for an Internet Web Hosting solution. Here are some of the key features:

  • Multiple internal and external switch stacks with Active/Standby failover
  • Cisco ASA firewall solution for security and VLAN aware ‘context’ configuration for virtual LANs
  • VLAN technology allowing separation of hosts/devices on the same physical network
  • Firewalls in Active/Active mode with state and configuration replication between devices, allowing customisable heartbeat/health checks and interface failover criteria
  • Redhat Linux and Windows Operating Systems running specific applications for the environment required
  • Linux Applications compiled from source for exact usage
  • Fast, reliable database platform for website backend
  • High Speed Network attached disk storage with access via CIFS for windows environments and NFS for Linux
