Technology in Action: Scalable, Secure, and Resilient Epic Deployment
Telefónica Tech deployed the Epic application service onto its own proven Epic hosting reference architecture. This facilitates Active:Active data centre application delivery of the Epic presentation and web services tiers, with data tiers made available across data centres using inter-DC availability groups and mirroring.
This custom deployment architecture allows for all tiers of the Epic application to reside in both data centres at all times, and to be moved and operated from each data centre as the service requires ensuring ongoing availability targets.
Outside of normal Active:Active delivery, all tiers are routinely moved and delivered from singular data centres to test and prove ongoing application service failover capability linked to contractual Recovery Time Objectives, and to allow for application and service uptime when undergoing the monthly and zero-day cyber patching routines.
