 通俗来讲，云硬盘就是网络硬盘，类似于网盘服务，通过网络访问对应的存储空间。那么，通常在哪些业务场景下，超级云硬盘的应用会带来事半功倍的效果，以及如何选择不同性能的超级云硬盘呢？我们总结了以下3种场景或应用：

1.高容量需求的应用

数据读写密集型应用场景，部署数据仓库适用于视频、音频、文档等对容量要求较高的应用。 建议选用高性能IO的超级云硬盘，满足低延迟、高读写速率以及大吞吐量的应用需求， 容量型硬盘支持TB级的单盘容积，灵活的计费模式，用量越多，单价越低。

2.开发测试业务

一般情况下，开发测试场景中对数据的可靠性有较高要求，该场景部署开发测试应用程序，建议选用普通IO超级云硬盘，满足开发、测试、部署、运维的需求。支持硬盘随时扩容，性能线性增长，并提供三副本存储，大幅提升数据可靠性。

3.大型数据库/大数据业务

部署分布式文件系统，具有高IOPS、高吞吐量、低延迟、大容量等特性能，满足大吞吐量、 高读写速率需求较高的大型数据库、大数据分析和计算、高可用容器集群的业务搭建。

通常来讲，裸金属服务器一定会具备独立物理服务器、VPC网络、自动化运维及超级云硬盘这4大特性，超级云硬盘作为裸金属服务器的重要特性之一，因其能满足弹性存储要求而颇受欢迎。当然，如果用户不选用超级云硬盘，裸金属服务器也支持使用本地硬盘。

The development of cloud disk has been very mature. As the basic block storage product of cloud computing scenario, it can provide persistent storage space for the virtual machine. For bare metal servers, the independent life cycle of cloud disk and distributed access based on network are also self-evident in the application of bare metal servers.

Bare metal exclusive physical server business host reference defines cloud disk as super cloud disk, which can provide block level data storage services for bare metal servers. Super cloud disk uses three copies technology for redundant storage to ensure data reliability and zero data loss. Based on the network distributed access, it provides the bare metal server with highly reliable and scalable hard disk.

According to the actual production environment, users can flexibly choose the size of specifications, and flexibly create, delete, mount, uninstall and expand the super cloud disk. In the operation and maintenance of the super cloud disk, users can format it, create a file system and other operations.

If you want to summarize the advantages and characteristics of the super cloud disk, large capacity, high reliability, scalability, high ease of use, low cost, etc., what are the specific aspects?

1. High reliability of data: distributed triple copy redundant storage, real-time synchronization, effectively avoiding single point failure risk of data

2. Performance guarantee: high IOPs, high throughput, low latency, meeting business scenarios with high requirements for IO performance.

3. Elastic capacity expansion: free configuration of storage capacity on demand, support for dynamic capacity expansion, and meet different IO performance requirements of users.

4. High cost performance: only pay for the current capacity and performance, and support a variety of ways to purchase on a monthly basis.

5. Independent persistence: it supports mounting to any bare metal server, and the data of the super cloud disk is independent and persistent.

6. Backup and recovery: supports backup and rollback operations through point in time snapshots, and data recovery by snapshot point at any time.

7. Easy to use: Super cloud disk can be managed and used through simple creation, mounting, unloading, deletion and other operations.

8. Multi specification optional: provide general cloud disk, high-efficiency cloud disk, SSD cloud disk and other hard disks with various performances to meet various storage requirements.

9. Data encryption: system disk and data disk are encrypted and saved to protect data security in all aspects.

10. Monitoring alarm: real time monitoring the read-write rate and throughput information of the super cloud disk, customizing the alarm rules, and automatically reminding the background.

11. Rich specifications: provide general cloud disk, efficient cloud disk, SSD cloud disk, etc., to ensure low latency and high performance, and support IO intensive business.

Generally speaking, cloud disk is a network hard disk, similar to the network disk service, which accesses the corresponding storage space through the network. So, in which business scenarios, the application of the super cloud disk will bring twice the result with half the effort, and how to choose the super cloud disk with different performance? We summarize the following three scenarios or applications:

1. Application of high capacity demand

Data read-write intensive application scenarios, deployment of data warehouse is suitable for video, audio, documents and other applications with high capacity requirements. It is recommended to select the super cloud disk with high performance IO to meet the application requirements of low latency, high read-write rate and large throughput. The capacity type hard disk supports the single disk volume of TB level, flexible billing mode, and the higher the consumption, the lower the unit price.

2. Develop test business

In general, there are high requirements for the reliability of data in the development and test scenario. In this scenario, the development and test application is deployed, and it is recommended to select common IO super cloud disk to meet the requirements of development, test, deployment and operation and maintenance. Support hard disk expansion at any time, performance linear growth, and provide three copies of storage, greatly improving data reliability.

3. Large database / big data business

Deploy the distributed file system, which has the special performance of high IOPs, high throughput, low latency and large capacity, and meet the business construction of large database, big data analysis and calculation, and high available container cluster with high throughput and high read-write rate requirements.

Generally speaking, the bare metal server must have the four characteristics of independent physical server, VPC network, automatic operation and maintenance and super cloud disk. As one of the important characteristics of the bare metal server, super cloud disk is popular because it can meet the requirements of elastic storage. Of course, if the user does not choose the super cloud disk, the bare metal server also supports the use of local hard disk.

The host reference newly launched the bare metal server rental product. The bare metal server is a physical cloud server rental service purchased on demand and paid by volume, which can provide a high-performance, secure and isolated physical server cluster dedicated to the cloud.
