Database Cloud & Consolidation Architectures

tank.infotech@gmail.com

Customers have 100s or 1000s of databases across their enterprise.

They want to lower costs by operating these databases on a centrally managed platform.

With only hardware consolidation, each database has an overhead, that prevents 100s of database from being placed on the same physical server.

The need for Database ConsolidationWhy…?
