Which of the following is not a requirement of an elastic system?

• CPU, GPU, RAM, storage availability
• Provision/deprovision resources
• Monitor resource usage
• Leprechauns

 

EXPLANATION

According to a paper from Karlsruhe Institute of Technology, "Elasticity is the degree to which a system is able to adapt to workload changes by provisioning and deprovisioning resources in an autonomic manner, such that at each point in time the available resources match the current demand as closely as possible." https://sdqweb.ipd.kit.edu/publications/pdfs/HeKoRe2013-ICAC-Elasticity.pdf
Resources such as CPU cycles, RAM, and storage are all necessary to provision to a client account. What makes elasticity different from simply being scale-able is that systems can be automated to add or remove these resources pending the outcome of a monitoring routine. Generally speaking, an elastic system doesn't require a Leprechauns to operate.
