Cloud Computing
The article discusses a cloud-based framework used in the management of both background services and foreground applications in the space of a system’s user. The framework addressed in this article is known as Orchestra. It is designed to solve the resource issues accruing from sudden operations on specific cloud instances. Background services cause sudden operations. The article refers to such resource issues as resource storms that lower the functionality of such foreground applications as DBMS and Web (Kim et al., 2018). The reduction in the performance of these applications results from the unreliable pre-empting done to the shared resources. As a consequence, the system suffers from poor user experiences and frequent violations of SLAs. Orchestra follows an online application in the mitigation of such issues.
Regarding the Reduced Operational Governance Control, the article states that the current cloud instances have limited abilities in the handling of resource storms. As a result, various firms face the challenge of reduced control over their applications. It gives an instance of Amazon videos and the problems that the firm gets after following the delay of the videos. Its customers tend to abandon a video every time it delays. The article addresses the Limited Portability Between Cloud Providers. Following its relationship between its background applications and the functionality of cloud instances, it shows that the success of a cloud service is subject to the status of background applications. Delays in such applications lead to challenges in cloud instances. As a result, the cloud provider involved faces the challenge of convenience and hence effecting the other providers in its line of service. The article also relates to Multi-Regional Compliance and Legal Issues. It states that without the application of Orchestra, it is challenging to have guaranteed background services SLAs. Such a challenge may lead to a violation of the set legalities by firms.
