Challenges in Cloud Computing

 Challenges in Cloud Computing Some of the challenges in cloud computing are explained as follows :  Data Protection The data protection is the crucial element of security that warrants scrutiny. In cloud, as data is stored on remote data center and managed by third party vendors. So, there is a fear of losing confidential data. Therefore, various cryptographic techniques have to be implemented to protect the confidential data.

 Data Recovery and Availability In cloud, the user’s data is scattered across the multiple datacenters therefore the recovery of such data is very difficult as user never comes to know what is the exact location of their data and don’t know how to recover that data. The availability of the cloud services are highly associated with downtime of the services which is mentioned in the agreement called Service Level Agreement (SLA). Therefore, any compromise in SLA may leads increase in downtime with less availability and may harm your business productivity. 

 Regulatory and Compliance Restrictions Many of the countries have Compliance Restrictions and regulation on usage of Cloud services. Therefore, the Government regulations in such countries do not allow providers to share customer's personal information and other sensitive information to outside states or country. In order to meet such requirements, cloud providers need to setup a data center or a storage site exclusively within that country to comply with regulations.

Management Capabilities The involvement of multiple cloud providers for in house services may leads to difficulty in management.

Interoperability and Compatibility Issue The services hosted by the organizations should have freedom to migrate the services in or out of the cloud which is very difficult in public clouds. The compatibility issue comes when organization wants to change the service provider. Most of the public cloud provides vendor dependent APIs for access and they may have their own proprietary solutions which may not be compatible with other providers.
