Upgrade and configuration change
After purchasing an Alibaba Cloud product, you can independently upgrade or downgrade your instance’s configuration or version as needed.
Use upgrades and configuration changes to meet business growth requirements, optimize cloud resource configuration, respond to changing workloads, or reduce costs.
Different cloud products support upgrades and configuration changes for various resource types, such as instance type, compute nodes, public bandwidth configuration, storage capacity, resource plan specifications, cloud disk type, resource performance, resource parameters, and billing method for instances.
Access path
You can usually perform upgrades and configuration changes in the console of the corresponding cloud product. Using Elastic Compute Service (ECS) as an example, to change the configuration of an ECS instance, go to the ECS console and modify the configuration for the specific instance.
In the Actions column for the target instance, click Change Configuration.
The following are typical scenarios and their upgrade or configuration change paths:
Notes
Upgrades and configuration changes for cloud products may have limitations or impacts. Pay attention to prompts in the interface or review the relevant documentation for the cloud product for details.
-
Different cloud products may have restrictions during upgrades and configuration changes.
For example, when modifying an instance’s peak bandwidth, you can only select a higher specification than the current one. Upgrades must stay within the same instance family and may require adjusting CPU, memory, or other resources simultaneously.
-
Upgrades and configuration changes may affect your resource fees, effective time, and billing method.
For example, an upgrade may require you to pay the price difference for the new specification or configuration within the current billing cycle.
-
Upgrades and configuration changes for some cloud products may briefly affect your business.
For example, upgrading or downgrading a Message Queue for Apache Kafka instance causes clients to disconnect from nodes and reconnect.
