Disaster Recovery

Adam Internet designs its network to withstand failure:

• Withstand failure of systems
• Withstand failure of procedures
• Withstand failure of environment

Adam Internet's network is robust, secure and fault tolerant.

Adam Internet has used its decades of network engineering experience to build a ‘loosely coupled’ disaster recovery system, rather than a
‘tightly coupled’ system. To understand the problems caused by tightly coupled systems, imagine railway carriages on a single track: an accident that pushes one carriage off the track will pull all the other carriages along with it, resulting in a total derailment. A loosely coupled railway on the other hand is flexible, allowing trains to use different tracks on their journey and only meeting where necessary.

Like a loosely coupled railway, Adam Internet’s system can quickly recover from a single point of failure via several layers of redundancy. Repair and maintenance work can be conducted at that one point of failure without disruption to other services. These layers are both logical and physical, ranging from full Border Gateway Patrol (BGP) capabilities to self-contained power generation.

The advantages of loosely coupled systems over tightly coupled systems are many:

• Greater scalability
• Higher reliability
  and fault-tolerance
• Ability to efficiently
  share resources.
