Block Storage
Cloud hard disk (EBS) is a basic cloud service that provides distributed block-level data storage with high reliability, high durability, and high scalability, ensuring that elastic cloud hosts (ECS) can read and write data quickly, efficiently, and safely. Each cloud disk adopts a mature redundancy strategy within the available domain to avoid single points of failure. At the same time, multiple types of cloud disks are provided to meet your various data storage needs.
Advantages
High reliability
Cloud disks are based on a distributed architecture, and data reliability is much higher than traditional physical hard disks.
Flexible expansion
A single disk supports a maximum capacity of 32TiB and supports online expansion of cloud disk capacity.
Safety
Simple and efficient data backup is achieved through snapshots, and cloud disk data encryption is supported.
Features
Standard HDD cloud disk
Standard HDD cloud drives support larger data disk storage and are suitable for applications with higher capacity requirements, such as video, audio, documents, etc.
SSD cloud disk
SSD cloud hard drives have ultra-high performance and data reliability, meeting the storage needs of key businesses.
High performance HDD cloud hard disk
High-performance HDD cloud disks have affordable prices and high I/O throughput capabilities, as well as high reliability, applicability, elastic scalability and other advantages, making them a cost-effective choice for users.
User cases
High performance computing
High-performance computing application scenarios and distributed file systems require the support of high-performance storage. It is recommended to use SSD cloud hard disk to meet the needs of large throughput and high read and write speed.
Enterprise applications
Enterprise office applications such as OA and email services have high requirements on business availability. For non-core business data, it is recommended to use high-performance HDD cloud disks.
Database
It is suitable for read and write intensive application scenarios and deploys various databases and data warehouses, such as SQL Server, MySQL, Oracle RAC, SAP HANA, etc. It is recommended to use SSD cloud disk to meet the requirements of low latency and high read and write speeds.
