Select 2 – An application has recently recorded this current profile for the utilization of the server-side components. The graph shows that within a short period of time several sudden utilization peaks have been recorded. Except for these isolated spikes the load is below 20%. Which two components of a Platform as a Service offering primarily contributes to handle the spikes in CPU utilization and ensures that the application meets the expected performance targets (i.e. < 40% CPU utilization)? [EXHIBIT]
Exhibit:
A. Runtime metering and monitoring services help detecting conditions that lead to peaks in CPU utilization and therefore react with the provision of additional resources.
B. Continuous delivery of services allow application developers to quickly provide patches so that a new code base can be deployed and more efficiently address load surges.
C. Identity management services allow strict control access to applications, prevent unauthorized access to unwanted clients, and reduce the CPU utilization of the computing nodes.
D. E-mail notification services can automatically inform system administrators of the application’s current state and allow them to promptly intervene with the addition of new computing resources.
E. Auto-scaling and cloud-bursting provide the capability of acquiring additional compute nodes and by joining the resource pool can help level down the overall server load. When the load stabilizes below the expected threshold, the resources can be relinquished.
