Related Terms and Instructions for Use

<p><strong>Region</strong></p> <p>The region consists of multiple physical data centers, such as East China 1 and Southern China 1.</p> <p><strong>Availability Zone</strong></p> <p>Availability zones are physical areas where the power and network are independent of each other in the same region. The physical distance between two availability zones is longer than 20 kilometers, such as EC1-A, SC1-B. In the same region, you can choose any available zone to design your local standby database service.</p> <p><strong>Master Node</strong></p> <p>Provide RDS instance connected by application servers, strongly recommend this instance and applications on ECS are in the same available zone.</p> <p><strong>Local Slave Node</strong></p> <p>When the available zone of master node is selected, the platform can recommend the most appropriate available zone for local slave node. You could also select an appropriate available zone according to the application design.</p> <p><strong>Slave Node</strong></p> <p>Slave node could be created in availability zones whether in the same region with master node or not. There is one and only one local slave node, and each remote region could create only one remote salve node. Data synchronization between master node and slave node may be delayed.</p> <p><strong>Read Only Node</strong></p> <p>You could create read only node to separate reading and writing according to the application design. Each remote availability zone could create only one remote read only node. Data synchronization between master node and read only node maybe be delayed. Read only node could do the following operations independently from the master node, such as upgrading version and computing capacity, restarting, setting white lists and releasing. The version of read only node must be greater than or equal to the master node.</p>
