About Orcon
Applications and data...
Most applications developed internally BSS (billing OSS (provisioning) “Other”
Housed in our own datacenters in Auckland and Wellington Lots of data
Financial and accounting (billing, GL, debtors, etc.) Business data (products, services, processes, IP, etc.) Customer-centric data (CDRs, usage logs, personal data) Customer-owned data (email, websites, databases, etc.)

Data and Applications
Example application - Cosmos

Design to Fail
…using Cosmos as our example application:
Multiple application frontends GSLB system in front of it Load balance sessions to different frontends Any can fail – sessions will be dropped, can log into another instance Replicated database behind it

Design to Fail
Other ideas we’ve had
cloud-based frontends cloud-based databases? challenges – local performance, soveregncy, service levels, security, isolation room for local cloud?
These may or may not turn into products that we sell to others as well

Design to Fail
Example – Christchurch
Scenario – Christchurch, but in AucklandScenario – Japan, but affecting western seaboard of USScenario – fire, malicious intent, network outage, loss of hardware/data loss
