Terms in this definition
- Premium
Hosting plan for Azure Functions that keeps instances pre-warmed to avoid cold starts and supports VNet integration. Executions time out after 30 minutes by default, which host.json can extend.
- Dedicated
Running Azure Functions on an App Service plan, which removes the execution time limit and offers VNet integration on Basic and higher tiers.
- Append
Policy effect in Azure that inserts fields only while a resource is being created or updated; resources that already exist are not corrected by it.
- Redundancy
So that hardware failures, datacentre outages or a regional disaster cannot destroy data, Azure Storage keeps multiple copies: only in the primary region with LRS and ZRS, or in a secondary region as well with GRS and GZRS.
- LRS
Locally redundant storage, the lowest-cost redundancy option, keeps three copies of the data inside a single datacentre in the primary region.
- ZRS
Zone-redundant storage: data is written three times, each copy in a different availability zone of the same region, and nothing is replicated to a secondary region.
