Resiliency

Bottlenecks and SPOFs

If you’ve ever built any enterprise level system you’ll be aware of the needs of performance and resiliency. You may do performance testing on your application; you may have a backup server in a second data center; you may even do regular “Disaster Recovery tests”. And yet, despite all these efforts, your application fails in unexpected ways or isn’t as resilient as you planned. Your primary server dies, the DR server doesn’t work properly.
