Availability Requirements

As shown in the table SLOs for Common IT Systems, different IT systems have different SLOs. Not all application systems need to meet the highest availability requirements.

Higher availability targets cost more to achieve, so you need to balance resilience and costs when defining your actual targets.

Once the system's availability target is set, you can follow resilience best practices to optimize it to achieve the desired availability.
