Benefits

Quick Deployment
Following the user's selection of an instance type and placing of an order, a highly available Percona instance with perfect monitoring and alarm features will be created in a few minutes. It can be put into operation to create values immediately.
High Reliability
The perfect automatic data backup mechanism is provided; by default, each instance is automatically backed up once per day and meanwhile, manual backup may be created according to the workload conditions, so that there is no risk of data loss。
High Availability
It supports such default features as primary and subordinate hot standby architecture, automatic fault transfer, persistent access to the database, automatic database backup, manual backup and others by default, which greatly improve the database reliability.
Elastic Scalability
It can be elastically expanded and upgraded on demand, improving the resource utilization rate and reducing the use cost. It supports the addition of read-only instances and effectively meets the requirements of business development for database performance。
Convenient Operation and Maintenance
The monitoring and automatic alarm features can reduce the costs for database and server network operation and maintenance, and there is no cost for equipment investment.

Features

High Usability

Quick Deployment

Following the user's selection of an instance type and placing of an order, a highly available Percona instance with perfect monitoring and alarm features will be created in a few minutes. It can be put into operation to create values immediately.

Convenient Operation and Maintenance

Provide real-time monitoring and automatic alarm function of database instance indicators, understand instance dynamic conditions anytime and anywhere; reduce user database operation and maintenance costs and server network operation and maintenance costs.

High Scalability

Elastic Expansion

The memory and disk space of the instances can be upgraded based on demand to improve the service processing capability. The upgrade process will not affect the normal access and use of the service, enabling fast and smooth capacity expansion that could rapidly meet the business development needs.

Read-only Instance

Support read-only instances, expand the read capability of the database horizontally; each read-only instance has an independent link address, and the application client can control the pressure distribution. Help users easily implement the read-write separation architecture to cope with the pressure of business massive requests.

High Reliability

Full Backup

The MySQL database is automatically backed up in full for 7 days each day at specified time; instant manual backups are also supported, and the storage used by the backup is all free of charge.

Incremental Backup

JCS for Percona can automatically back up the incremental portion of database of the past 7 days to achieve rollback based on any point in time.

Data Recovery

It supports one-click recovery of backing up data to current instance; in addition, based on incremental backup, it supports creation of a new database instance based on the data at any time point within 7 days.

High Security

Security Mode

The default JCS for Percona instance applies standard mode, it supports switching to high security mode, it owns certain SQL interception capabilities, and also provides SQL auditing.

Scenarios

LAMP Website Scenario

JD Cloud provides Virtual Machines and JCS for Percona products necessary for LAMP website, making it convenient to deploy your website on JD Cloud. Meanwhile, multiple auxiliary operation & maintenance capacities (e.g. monitoring, backup and security protection) and its high-backup and high-availability structure enable you to focus on website construction.

Read-write Separation Scenario

To apply in the circumstance with relatively high reading requirement and cope with the traffic peak to be read in a short time, one or several read-only instances can be created on the JCS for Percona. Each read-only instance has an independent link address. Thus, the application client can share the reading pressure equally.
