Service Level Agreement (SLA)
- It is the commitment of Microsoft for the uptime and connectivity of a service.
- You could obtain a service credit if the service level agreement is not met by Microsoft.
- Composite SLAs include several resources (with different availability levels) to support an application.
- SLAs for multi-region deployments distribute the application in more than one region for high availability and use Azure Traffic Manager for failover if one region fails.
- Private Preview is only available to a few customers for early access to new technologies and features.
- Public Preview makes the service in the public phase and can be used by any customers to evaluate the new features but SLA does not apply.
- General Availability is the release of service to the general public and is fully supported by SLAs.
- Azure updates allow you to get the latest updates on any Azure products and features.
