Requirements of Single Instance SLA RRS feed

  • Question

  • Hi

    I know Azure now offers 99.9% SLA on single instance of virtual machine provided you meet some requirements. The requirements I believe are you must use premium storage (SSD) for all drives.

    Does this means using a DS* series VM fulfills this requirement and as long as any extra disk I attach to that VM is also SSD, I am covered with that SLA?

    Thanks, Piyush

  • In addition to Mustafa’s reply: Yes, you are covered with that SLA if you are using a DS* series VM that fulfills this requirement as long as any extra disk you attach to that VM is also SSD.

  • Hi Sam, Piyush,

    Having read the SLA information, for a single instance VM with Premium Storage the SLA is reduce to 99.9% which amounts to a potential downtime of 8h and 45 mins per year.

    Can you tell me how much notice do we get from MSFT for planned maintenance (as I suspect the downtime above is primarily due to maintenance carried out)?

    Thanks,

  • During planned maintenance outages for VM's warnings are sent to customers when Azure is about to be updated. Notification sent at least 30 days before the impact.

    Both pre-emptive maintenance and scheduled maintenance phases begin with a notification. Expect to receive a single notification per Azure subscription. The notification is sent to the subscription’s admin and co-admin by default. You can also configure the audience for the maintenance notification.
