* In case of Geo-zone-redundant storage (GZRS), data is synchronously replicated 3 times across 3 availability zones in the primary region, then asynchronously replicated to the secondary paired region (3 more copies) = can sustain node failure within the storage cluster, entire datacenter or availability zone going down or a region-wide outage (only region failure would require account failover to restore read and write availability. Typically has an RTO of less 1 hour (no SLA).
* Microsoft Dapr (Distributed Application Runtime) is an open-source, event-driven framework aimed to build resilient and portable microservices for Cloud and Edge applications.

* By connecting Azure Boards with GitHub repositories, you enable linking between GitHub commits, pull requests, and issues to work items.

A script can be included in the template, or stored in an external source and referenced in the template.

* You can combine both VM and disk bursting (generally available in April) to get higher performance on your VM or disks without overprovisioning. VM bursting, which is enabled by default, offers you the ability to achieve higher throughput for a short duration on your virtual machine instance with no additional steps or cost. Currently available on all Lsv2-series VMs in all supported regions, VM bursting is great for a wide range of scenarios like handling unforeseen spiky disk traffic smoothly, or processing batched jobs with speed. With VM bursting, you can see up to 8X improvement in throughput when bursting.
