This topic describes how to upgrade the specifications of an ApsaraDB MyBase instance
to improve overall performance for short-term use. This helps you handle traffic spikes
during events, such as 6.18 Midyear Shopping Festival and Double 11. For example,
you can increase the number of CPU cores and the amount of memory for your instance.
Description
ApsaraDB MyBase provides the elastic scaling feature. You can use this feature to
increase the CPU cores, memory, and other resources for an ApsaraDB MyBase instance
for a specified short period of time. This improves the overall performance of the
instance for short-term use. When the specified period of time ends, the system restores
your instance to the specifications before the temporary upgrade.
If an online store receives 100,000 visits per day on average, an instance with 2
CPU cores and 16 GB memory can ensure stable online services. However, historical
statistics show that the number of visits on Double 11 may reach one million. To handle
the peak-hour traffic, the online store can increase the number of CPU cores to 8
and increase the memory to 64 GB for a short period of time.
Note
- Temporary upgrades do not cause service interruptions or other negative effects.
- You must wait approximately 2 minutes for the temporary upgrade to take effect.
Procedure
- Log on to the ApsaraDB MyBase console.
- In the upper-left corner of the RDS Dedicated Clusters page, select the region where the instance that you want to scale up is deployed.
- In the left-side navigation pane, click Clusters. On the page that appears, find the ApsaraDB MyBase for MySQL dedicated cluster in
which the instance to be scaled up is deployed, and click in the Actions column.
- In the left-side navigation pane, click Instances. Find the instance that you want to manage and choose in the Actions column.
