Cloud Resource Management – A Survey

Abstract: Cloud computing is a delivery of computing as a service with shared resources, software and information over a network. The key advantage of the cloud is the flexibility and scalability. Due to its widespread nature of computing technologies all the IT organisations are drawn towards cloud. Cloud provides different service models like platform as a service, infrastructure as a service and software as a service. Cloud contains different infrastructure like storage, server and networks and applications like web apps and database. Cloud provides on demand access to shared resources and services which are hosted on datacenters at cloud providers. Effective management of these shared resources and services is a major requirement of cloud computing. Cloud management is complex and faces great challenges due to different infrastructure, different vendors and business view point of different users. Several cloud management challenges includes security, abstraction, processes, policies, dynamism, network resource management, corporate account management etc. The traditional cloud management requires installation of software, updates and patches. This software is different for a different infrastructure vendor hence increases the complexity of management. Hence to overcome this, there is a need of management framework which manages all the functions irrespective of vendors. This paper provides a survey of different management model proposed by many authors.
