Now growth of full range of services in the field of cloud computing is watched. This service is available for a large number of users. There is a whole new trend in the design of software applications focused on the processing of big data. Thus, the adoption of cloud technologies has defined the appearance of new approaches to query optimization in cloud databases. The article analyzes the effective methods to solve the query optimization tasks. The defines the main directions allowing optimizing queries to the cloud database: in cloud data centers in the SQL format and the new in the paradigm of building queries NoSQL. In the article the architecture-specific solutions, feature of which is the use of the dynamic approach.Results of experimental research are presented and the advantages and disadvantages of the approaches optimizationquerymethods.
