Discussion
In this chapter, we presented the design and implementation details
3
of an end-to-
end framework that facilitates adaptive and dynamic provisioning of the database
tier of the software applications based on consumer-centric policies for satisfying
their own SLA performance requirements, avoiding the cost of any SLA violation
and controlling the monetary cost of the allocated computing resources. The
framework provides the consumer applications with declarative and flexible mech-
anisms for defining their specific requirements for fine-grained SLA metrics at the
application level. The framework is database platform-agnostic, uses virtualization-
based database replication mechanisms and requires zero source code changes of
the cloud-hosted software applications.
