Internet and network application are growing very fast and use of cloud computing has increased rapidly in today’s world. Cloud computing provides many advantages such as low cost, on-line, on-demand services pay per use basis and accessibility of data. Security in cloud computing is major issue, as user often store sensitive information in cloud storage provider but these providers may be untrusted. Encryption algorithms play a main role in information security systems. Several issues as scalability, security, performance, integrity etc. are discussed so far. This paper surveys recent research related to multi cloud security and address possible solution. This paper introduces a better load balance technique for public cloud based on data distribution system over the database server. It is found in research that use of multi-cloud providers to maintain security has received less attention than single clouds. This work aims to promote the use of multi cloud due to its ability to reduce security risks that affect the cloud computing user. The way to secure the data using different compression and encryption algorithms and to hide its location from the users that stores and retrieves it.
