Cloud Management and Monitoring
In this chapter, we start by introducing Cloud Computing management terms, with a special reference to Amazon Web Services (AWS). Next, we review the performance characteristics of public, multi-tenanted data centers, including the concept of noisy neighbors. If a particular VM does excessive I/O or memory accesses, then other VMs running on that same server will experience a slowdown in their access of the same physical resource. This results in a performance variation experienced by a VM user over time. Such factors impact run times of users’ applications and result in different costs to finish a task. Cloud users want to maximize their performance and/or minimize their costs. We look at various monitoring tools, to manage the user costs. Since a majority of data in the public Cloud consist of images, we then visit the monitoring and security of these images, digital watermarking, and data provenance. Lastly, a description of Follow-Me Cloud to minimize latency and security wraps up this chapter.
