Data migration and replication issues in cloud computing

Abstract

Cloud service providers have more reputation for data storage service and offering unlimited storage, data availability, better scalability due to this benefits so many clients are motivated to store their data in cloud storage. But cloud service providers always can't guarantee the quality of service or may be violating the SLAs due to this data migration is required so cache as service can overcome migration issues. Cache is a significant part of any client-server application due to its advantages can reduce the delayed access of any form and provide conventional latency and fast response time to reach the growing mass of users. Implementing a Cache-as-a-Service across the data centres will allow multiple data centres to access managed in-memory cache instead of a direct datacenter.
