Telefonica Background

In addition to the functions of a traditional database, the RDS provides the following functions:

Professional database management platform

  • The RDS console provides comprehensive function menus allowing for easy, secure, browser-based database management and maintenance. Database management and maintenance functions include:
    • Active/standby environment setup
    • Data migration
    • Performance scale-up
    • Backup and restoration
    • Operating status monitoring
    • Log management
    • Parameter adjustment

Simple backup and restoration

  • On the RDS console, only a few clicks are necessary to perform manual data backup or set an automatic backup policy to back up data to secure and stable object-based storage (OBS) space. You can also restore any backup data from the most recent seven days.

Perfect monitoring system

  • On the RDS console, you can use the dashboard and instance list to view the operating status of created instances. There are about 20performance resource monitoring views to observe the current and historical operating status of database instances, as well as error logs and slow query logs.

Database performance optimization

  • Identify performance bottlenecks and locate faults or exceptions by observing the operating status and log statistics.
  • To meet service requirements, optimize database performance by:
    • Scaling instances up or out
    • Customsing or adjusting database parameters
Category Feature Sub-Feature Description
Instance management         Instance provisioning         Provisioning wizard Provides a walkthrough on provisioning an RDS instance.
Setting a cloud service region Selects the region where a database server is located.
Setting the database type Selects a database type. Currently, only MySQL is supported.
Setting the database version Selects a database version. Currently, only MySQL 5.6.22 is supported.
Setting performance specifications Selects performance specifications.
Setting the storage type Selects a data disk storage type.
Setting the storage space Selects the data disk storage capacity.
Setting the available zone (AZ) Selects the AZ where a database server can be located.
Setting network deployment Selects Private Network deployment mode.
Setting the virtual private cloud (VPC) Selects the network service domain where a database server is located.
Setting a subnet Selects a subnet under a VPC.
Setting database parameters Creates database and administrator accounts when creating an instance.
Setting a backup policy Sets a backup policy when creating an instance.
Instance list Displaying instance information

Displays certain key information about an RDS instance, such as:

  • Instance name
  • Cloud service region
  • Database type
  • Database version
  • IP address
  • Creation time
  • Operating status
  • Allowed operations
Sorting instances by fields Sorts instances by instance name, cloud service region, and database type.
Updating the instance list Manually updates the instance list. Automatic updating is not supported.
Instance operations Managing instances Maintains basic information about an RDS instance.
Binding a public network IP address to the RDS instance To access the RDS instance from a public network, bind a public network IP address to the RDS instance.
Setting a whitelist Sets the IP addresses that can be used to access an RDS instance, which improves security.
Restarting an instance Restarts an instance to restore it after modifying parameters or when the instance becomes abnormal.
Adding a standby RDS instance Creates a read-only instance based on service requirements, which decreases the data reading workload on the active instance.
Setting a standby RDS instance to the active RDS instance Manually sets a read-only instance to the active instance if the active instance becomes faulty.
Scaling up an instance Adjusts performance specifications and disk capacity of an instance.
Deleting an instance Deletes an instance actively, or, when it expires, passively.
Instance access Instance access implemented using a private network IP address   Supports random IP address allocation.
Instance access implemented using a port   Uses the default port.
Data migration Importing local service data to the RDS   Provides the importing method on the console page, including the principle view and detailed command reference. Currently, only MySQL 5.6.22 data is able to be imported into the RDS. The RDS may be incompatible with the data of other database types and versions.
Migrating a local database instance to the RDS  

Provides the following importing method on the management control page:

  1. Back up and compress the local database.
  2. Upload it to the OBS.
  3. Select and import the local database to the instance on the RDS management page.
Currently, only MySQL 5.6.22 data is able to be migrated to the RDS. The RDS may be incompatible with the data of other database types and versions.
Data backup and restoration Automatic backup  
  • Supports a maximum of seven automatic backups for each instance.
  • Saves each automatic backup for seven days by default.
  • Sets the backup period on a weekly basis. If data is backed up every day, a maximum of seven automatic backups exist at the same time.
  • Specifies the backup start time. If the backup is not completed within 20 hours, the backup fails.
  • Saves backup files to the OBS.
The MySQL database instance uses the innobackupex tool to back up data and ensure data consistency.
Manual backup  
  • Manually performs physical backup immediately.
  • Saves backup files to the OBS.
  • Supports a maximum of three manual backups for each instance.
The MySQL database instance uses the innobackupex tool to back up data and ensure data consistency.
Data restoration from backup files   Restores databases from automatic or manual backup files.
Database and account management Online database management   Manages databases only using the console. Account root is unavailable.
Online database account management   Manages rights of database accounts only using the console. Account root is unavailable.
Database parameter configuration Online parameter viewing and modifying   Modifies data start and operating parameters.
Restoration of default parameter settings   Restores default parameter settings if parameter setting modification causes databases to stop.

Switching between monitoring time windows   Supports 3-hour, 12-hour, 24-hour, 7-day, and 30-day monitoring time.
Log query Error logging   Records error data that you can search based on start and end time, which helps troubleshoot faults that occur during database operating.
Slow query logging   Records data that you can search based on start and end time, which helps identify the root causes of slow SQL statements.
