Telecommunication service providers (Telcos in short) and Enterprises are following an industry transformation of moving to a cloud-based IT infrastructure to reduce cost by leverage leveraging a shared execution environment based on commodity Common Off The Shelf (COTS) servers. Telcos have the additional burden of moving from dedicated fixed function hardware with a vertically integrated software stack to commodity COTS hardware where independent software applications must seamlessly interoperateintegrate well, inter-operate and meet the required stringent Service Level Agreements (SLAs).
The requirement for Highly Available (HA) applications and services does not change during this migration so adding to the burden that the target cloud infrastructure must provide equivalent mechanisms for High Availability. For example, Telcos will still require 5NINES of availability for services; a feature that Telco customers rely upon. In addition, enterprises often rely on applications where a single second of unavailability could incur millions of dollars in lost revenue. For many large service providers and enterprises the public cloud is not an option due to cost or security issues. A private cloud infrastructure provider that can deliver a level of high availability expected by these large customers stands to acquire a large and loyal following. Sunku → Is there a proof for this that we can add in reference section? alternatively we could make it easy and say private cloud is preferred over public cloud.
