Abstract
With the growing popularity of cloud computing and large number of providers, it is necessary to select the most appropriate service. To select a suitable provider the user needs to browse a huge list of providers. To solve this problem, the customer can use a third-party service called a cloud broker. One of the problem we faced during the developing cloud broker framework is a lack of API standards. Every provider has its own protocol for deploying services. This paper describes a new approach to construct a protocol for communication between the client and the provider. It is based on the use of mediators, which, depending on the selected service capable to convert messages from a format of one particular provider to a format of another provider. All the processes described in a specific example of Google Compute Engine client and Digital Ocean server interactions for deploying the service. In addition, during the development of mediators was introduced a new operator “sync” to synchronize the set of answers to one.
