You are working on a virtual guest design for the deployment of a critical business application. The
software vendor has provided you with detailed application requirements for the projected
workloads. Which of the following scaling approaches does this describe?
A.
Adaptive
B.
Predictive
Explanation:
There are two types of scaling approaches in virtual platforms: adaptive and predictive.
Bothapproaches are usable; however, a designer must work out which is the best approach for
each project.
The adaptive approach to guest virtual machine design is a major advantage that virtualization
technologybrings to a datacenter. It allows a guest virtual machine to be created initially on a few
metrics or high-levelrequirements (such as a limited budget) and scaled (that is, grown, not
shrunk) through the virtual machine lifecycle. In many cases, this scaling can be performed hot/live
without outage/downtime to the runningapplications.
The predictive approach, on the other hand, requires more planning and research, and you must
know themetrics before deployment. The advantage here is that once the virtual machine has
been deployed, onlyapplication maintenance is required. The application requirements are known.
