Elastic Compute Service:Instance types that use local disks

Last Updated:Jul 08, 2024

This topic describes the features of Elastic Compute Service (ECS) instance families equipped with local SSDs and lists the instance types of each instance family.

Overview

Instances equipped with local SSDs provide high I/O performance. They are suitable for scenarios that place high demands on storage I/O performance and require a high availability architecture at the application layer. For example, they are suitable for NoSQL databases, massively parallel processing (MPP) data warehouses, and distributed file systems.

Instances equipped with local SSDs are suitable for enterprises that provide online services such as online gaming, e-commerce, live video streaming, and media. These instances can satisfy the requirements that I/O-intensive applications have for low latency and high I/O performance of block storage devices.

Instances equipped with local SSDs have the following characteristics:

  • Deliver up to hundreds of thousands of low-latency random read/write IOPS for large databases.

  • Offer a maximum sequential read/write throughput of several gibibytes per second in big data, parallel computing, and other large dataset scenarios.

  • Use local Non-Volatile Memory Express (NVMe) SSDs to deliver hundreds of thousands of random read/write IOPS with single-digit microsecond latency.

When you use instances equipped with local SSDs, take note of the following items:

  • Instances equipped with local SSDs do not support instance configuration changes or failovers.

  • Local disks can be tied only to specific instance types. The number and capacity of local disks attached to an instance vary based on the instance type. You cannot separately purchase local disks, or detach local disks from instances and then attach the disks to other instances.

  • You cannot create snapshots for local disks. If you want to create an image from the system disk and data disks of an instance equipped with local SSDs, we recommend that you create an image by combining the snapshots of both the system disk and data disks. In this case, the data disks must be cloud disks.

  • You cannot create images that consist of system disk snapshots and data disk snapshots based on instances equipped with local SSDs.

  • You can attach a standard SSD to an instance equipped with local SSDs and extend the capacity of the standard SSD.

  • Operations on an instance that are equipped with local SSDs may affect the data stored on the local SSDs. For more information, see the Impacts of instance operations on data stored on local disks section of the "Local disks" topic.
