Before You Start

GaussDB is a distributed relational database. GaussDB supports distributed transactions and intra-city deployment across AZs for zero data loss, storage for petabytes of data, and scale-out to more than 1,000 nodes. It is highly available, secure, and scalable and provides services including quick deployment, backup, restoration, monitoring, and alarm reporting for enterprises.

For operation details, see API Overview.

Endpoints

An endpoint is the request address for calling an API. Endpoints vary depending on services and regions. For the endpoints of all services, contact the enterprise administrator.

Concepts

  • User

    A user is created using an account to use cloud services. Each user has its own identity credentials (password and access keys).

    The account name, username, and password will be required for API authentication.

  • Region

    A region is a geographic area in which cloud resources are deployed. Availability zones (AZs) in the same region can communicate with each other over an intranet, while AZs in different regions are isolated from each other. Deploying cloud resources in different regions can better suit certain user requirements or comply with local laws or regulations.

  • AZ

    An AZ contains one or more physical data centers. Each AZ has independent cooling, fire extinguishing, moisture-proof, and electricity facilities. Within an AZ, computing, network, storage, and other resources are logically divided into multiple clusters. AZs within a region are interconnected using high-speed optical fibers to support cross-AZ high-availability systems.
