Microsoft's Azure cloud computing service has a new high-availability service called Azure Availability Zones. Currently, the service is in beta trials in the East U.S. 2 and West Europe regions. When it reaches general availability status, it will carry a 99.99 percent uptime guarantee. Microsoft says it plans to roll Availability Zones out to other regions by the end of the year.
"Availability Zones increase Azure's resiliency capabilities and broaden options for customers to choose the business continuity solution that is right for their organization," explained Tom Keane, head of Global Infrastructure at Microsoft Azure, in a blog post announcing the new service. "We've also designed Availability Zones to give customers great confidence in delivering services with an industry-leading, financially-backed 99.99 percent virtual machines uptime SLA [service-level agreement] when generally available."
