Scale-out of database systems in cloud computing environments

A non-transitory computer-readable storage medium coupled to one or more processors and having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations for scaling of a system executed within a cloud computing environment, the operations comprising:

• providing a first instance of a database system within the cloud computing environment;
• determining that scale out of the database system is to be executed, and in response:
• providing a second instance of the database system within the cloud computing environment, the first instance and the second instance collectively defining a cluster,
• establish a remote direct memory access (RDMA) connection between the first instance and the second instance,
• copying data stored within the first instance to a data store of the second instance over the RDMA connection, and
• configuring the first instance to replicate a first transaction log to the second instance over the RDMA connection;
• and
• receiving, by each of the first instance and the second instance, requests from one or more client devices.
