Instance families with local SSDs offer CPU-to-memory ratios of 1:4 and 1:8. They are suitable for scenarios such as online transaction processing (OLTP) and high-performance relational databases, NoSQL databases such as Cassandra and MongoDB, search scenarios that use solutions such as Elasticsearch, and E-MapReduce big data scenarios such as storage and computing separation.

Overview
The durability of data stored on a local disk is determined by the reliability of the associated physical machine. The risk of a single point of failure exists. Data stored on local disks may be lost when a hardware failure occurs on their associated physical machine. We recommend that you store only temporary data on local disks. For more information, see Local disks.
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.
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.

Supports standard SSDs and ultra disks.
Network:
Provides high network performance based on large computing capacity.
Supported scenarios:
OLTP and high-performance relational databases
NoSQL databases such as Cassandra and MongoDB
Search scenarios that use solutions such as Elasticsearch
