Mobile operator in Europe meets uptime SLA for their billing systems with FlashGrid for Oracle RAC on Azure
Uptime SLA of 99.99% or better was a central requirement for a mobile operator in Europe in 2018 when they were starting deployment of a new billing system on Azure cloud. The biggest challenge was achieving the required uptime SLA for the backend Oracle Database. After discussions with the billing system vendor the only practical solution identified was running 3-node Oracle RAC clusters spread across three availability zones. With such configuration the database could survive the loss of two database nodes, or loss of an entire availability zone.
FlashGrid Inc partnered with the billing system vendor, and with TCS, a global IT services provider, to deliver the complete solution that included more than 20 Oracle RAC database clusters powered by FlashGrid engineered cloud systems.
