SLO, service level objectives |
overview |
{{site.data.keyword.attribute-definition-list}}
{: #slo}
Service level objectives (SLOs) describe the design points that the {{site.data.keyword.cloud}} services are engineered to meet in the following areas:
- Availability
- Operations management
- Performance
The SLO is not a warranty and IBM will not issue credits for failure to meet an objective. Refer to the Service Level Agreements (SLAs) for commitments and credits that are issued for failure to meet any committed SLAs.
The following tables describe the service level objectives (SLOs) for the {{site.data.keyword.cloud_notm}} services in a high availability configuration. As you aggregate or deploy services into a single zone, your SLO might vary. For more information about how {{site.data.keyword.cloud_notm}} is striving to ensure the highest availability of services, see How IBM Cloud ensures high availability and disaster recovery.
