Title: AVAILABILITY MANAGEMENT IN A DISTRIBUTED COMPUTING SYSTEM
Abstract:
Methods and systems for implementing an availability management system for implementing availability management, in distributed computing systems, are provided. An availability management system implements an availability manager and availability configuration interface to meet availability guarantees for tenant infrastructure. The availability management systems operates with availability zones, computing clusters, fault and upgrade domains to allocate and de-allocate virtual machine sets of virtual machine instances to a distributed computing system based on tenant-defined availability parameters. The availability manager is configured to: based on an availability profile, allocate the virtual machine sets across availability zones using an allocation scheme. The allocation scheme is a virtual machine set spanning availability zones allocation scheme for performing evaluations to determine an allocation configuration defined across at least two availability zones for allocating virtual machine sets. When the allocation configuration meets the availability parameters, the allocation scheme selects the allocation configuration for allocating the virtual machine set.
