  availability zone

  A physical region where resources use independent power supply and networks. AZs are physically isolated but interconnected through the internal network. To enhance application availability, you are advised to create instances in different AZs.

  Dedicated Distributed Storage Service

  Dedicated Distributed Storage Service (DSS)?provides you with dedicated storage pools which are physically isolated from other pools to ensure high security. With data redundancy and cache acceleration technologies, DSS can deliver highly reliable, durable, low-latency, and stable storage resources. By flexibly interconnecting with various computing services, such as Dedicated Computing Cluster (DCC), Elastic Cloud Server (ECS), and Bare Metal Server (BMS), DSS is perfect for different scenarios, such as high performance computing (HPC), online analytical processing (OLAP), and hybrid loads.

• E

  Elastic Cloud Server

  An Elastic Cloud Server (ECS) is a computing server consisting of CPUs, memory, images, and Elastic Volume Service (EVS) disks that allow on-demand allocation and elastic scaling. ECSs integrate Virtual Private Cloud (VPC), virtual firewalls, and multi-data-copy capabilities to create an efficient, reliable, and secure computing environment. This ensures stable and uninterrupted operation of services.
