Customers can access databases from cloud database service providers through the Internet and deliver them to users when they need them. In other words, cloud databases are designed for virtualized computer environments. Cloud databases are realized by using cloud computing, that is, using the software and hardware resources of cloud computing service providers. Cloud computing is growing rapidly in the global IT industry. Many companies have started to move to cloud computing and access data from cloud databases. According to one survey, nearly 36 percent of companies run applications through cloud database (Mimecast Survey, 2011). Cloud computing can be called a new dimension in the IT world in terms of cost savings and faster application performance. This trend in enterprises shows that in the near future, enterprises will start to rely on cloud applications. Cloud databases are primarily used as services. It is also known as Database as a Service (DBaaS). Cloud databases will become the most commonly adopted technology for storing massive amounts of data by many businesses around the world. It's not as simple as taking a relational database and deploying it on a cloud server. Not only that. This means adding additional nodes when needed online and increasing the performance of the database. Data needs to be distributed across 2 data centers in different locations International Journal of Database Management Systems (IJDMS) Vol.5, No.2, April 2013. Databases must always be accessible so that users can get data whenever they need it. Cloud databases must be easy to manage and should also reduce costs (Curino, Madden, etc.). Cloud computing is very effective in recovering information after a database disaster. With the ever-increasing demands and technological advancements, usage patterns of cloud databases were invented. At the beginning of the birth of the cloud database, customers accessing the cloud database could only use the read facility. However, depending on the client's requirements, it also involves writing queries. The introduction of Web 2.0 made this possible. Observe that the number of read requests to the database is still greater than the number of write requests. But in the near future, as business applications also depend on cloud computing, the number of reads from cloud databases will also increase (Hogan, 2008). This trend has started to close the gap between read and write requests to cloud databases
