Terms in this definition
- Virtual machines
Infrastructure-as-a-service compute giving complete control of the operating system, making it a fit for lift-and-shift moves and for software relying on OS-level pieces like COM.
- WHERE
Limits a SELECT, UPDATE or DELETE to just the rows meeting a condition. Omit it, and the statement hits every row.
- Azure Service Health
Dashboard tailored to your subscriptions that reports Azure platform outages, scheduled maintenance and health advisories affecting them.
- Azure Functions trigger
Every function is started by exactly one thing. That thing might be a web call over HTTP, a schedule, the arrival of a blob, a message landing in a queue or a change in a database.
Related terms
- Alert processing rule
Acts on already-fired Azure Monitor alerts at scale, suppressing notifications (during planned maintenance, say) or attaching action groups.
- Service Health alerts
When planned maintenance, a health advisory or a service issue hits one of your subscriptions, these activity log alerts fire an action group to contact you by SMS, email, push notification, webhook or Logic Apps.
- Update domain
During planned maintenance, VMs in the same one of these groups reboot together, and only one group is rebooted at a time. Availability sets default to 5 and allow up to 20.
