Infrastructure

Replicated Data Centres

To ensure resilience our infrastructure is dual-located - all our equipment is replicated in two physically different locations providing a complete standby service.

Our data centres are located in the UK.

Platform

Our production platform is Microsoft Windows .Net based. Our application stack is .Net v2 based.

A number of monitoring services are in-place, and are available for customer use. For example, to measure up-time and system performance.

Database

The client databases are hosted on dedicated servers running Microsoft SQL Server. Each database is replicated between the data centres to ensure service continuity.

Liberty Web Services

To ensure service availability, ediTRACK operates a 'web farm' of Liberty Servers. This approach allows the access to the ediTRACK service to be balanced across several servers enabling optimum performance to be provided at all times. Through operating a web farm, catastrophic web server failure will not have a disastrous effect upon clients using the service, as the access will be routed into another web server.

Internet Connectivity

We have a 100mbit dual stream connection to the Internet from both our data centres. The data centre's are interconnected connected by a 100mbit direct wired connection.

Hardware

We primarily use a range of HP servers in our data centres, with a small amount of IBM and Dell equipment. Cisco is our main provider of switches and other network.

We maintain an unused equipment float (production class servers etc. that are configured but not used), to cover 150% of our ongoing production capacity. This allows us to hot-swap failed components without resort to our DR contractors.

Firewalls

Publicly available services are secured within the demilitarised zone of the Firewall configuration. Various reporting mechanisms are in place to enable automatic intrusion detection and other security issues.
