Question
You are a VMware architect employed to design and build application environments and the underlying platform for a software development company. The company is using a "devops" approach and has engaged with you at the beginning of the first planning meeting/pre-sprint. The software has yet to be written. However, you have some high-level specifications that are subject to change at each of the early meetings. The ______ is more logical for virtual machine sizing.
Options
- Apredictive sizing approach based on current software
- Badaptive sizing approach

Explanation
There are two types of scaling approaches in virtual platforms: adaptive and predictive. Both approaches are usable; however, a designer must work out which is the best approach for each The adaptive approach to guest virtual machine design is a major advantage that virtualization technology brings to a datacenter. It allows a guest virtual machine to be created initially on a few metrics or high-level requirements (such as a limited budget) and scaled (that is, grown, not shrunk) through the virtual machine life cycle. In many cases, this scaling can be performed hot/live without outage/downtime to the running applications. The predictive approach, on the other hand, requires more planning and research, and you must know the metrics before deployment. The advantage here is that once the virtual machine has been deployed, only application maintenance is required. The application requirements are Chapter 5, Design Approaches
