Differences between an on-premises and Azure implementation
Interesting comparison from an official Azure documentation article -
On-premises implementation | Azure implementation | |
---|---|---|
Networking | LAN/WAN | SDN (software-defined networking) |
Security group | IP/port restriction tools | Network Security Group (NSG) |
Resilience | MTBF (mean time between failures) | MTTR (mean time to recovery) |
Planned maintenance | Patching/upgrades | Availability sets (patching/upgrades managed by Azure) |
Resource | Dedicated | Shared with other clients |
Regions | Datacenters | Region pairs |
Storage | SAN/physical disks | Azure-managed storage |
Scale | Vertical scale | Horizontal scale |
