Which method provides this function?

Review Case

Refer to Case 3.

You must design the compute scalability functions for your administrator in a DIY private cloud. You want to use extra pools that have known performance and capacity characteristics along with orchestration tools to automate most of the deployment process.

Which method provides this function?
A . Define a compute pool as a known unit of consumption
B . Define storage limits in a consumption pool
C . Add more servers to the existing pool
D . Add VMs to the existing servers in the compute pool

Answer: A

Explanation:

There are various options to compute scalability. Some of them are:

• The first option is to scale-up by adding resources such as processor and RAM to the existing servers in the compute pool. This option is mostly a manual process and requires you to define the processes to move services between hosts to avoid outages.

• The second option is to add more servers to the existing pool. In this option, completely documenting the standard server configuration is necessary to ensure that any extra servers purchased have similar performance characteristics. Although it involves manual processes, use of orchestration and

configuration management tools can control and automate some of the work. These tools enable to deploy resources more rapidly and to ensure a consistent configuration across hosts.

• The final option is to define or add a compute pool as a known unit of consumption. Again, a documented, standard server configuration is necessary to ensure similar performance characteristics. As more resources are required, you can add extra pools to the infrastructure that is having a known performance and capacity characteristics. This option also requires orchestration and configuration management tools for a more efficient and consistent deployment process.
