Data Migration Techniques in Cloud

Cloud computing is a trending paradigm that combines several computing concepts and technologies of the Internet to create a platform for more agile, cost effective and reliable model for the public users, business applications and IT infrastructure. There are various requirements that need to be addressed by Cloud Service Provider (CSP) for enabling the cloud services to the users such as security, performance, availability, integrity, customization with minimal cost. If any of these requirements are not met, then the user wishes to switch from current CSP to a new CSP. To achieve that the user has to download all the digital assets, services, IT resources and applications from one CSP and upload into another CSP. This process has many issues like security, vendor management, technical integration, requirement of time and energy resources, etc; here we propose a secure data migration technique to migrate the data from one cloud storage system to another cloud storage system.
