(Verse 1) Availability sets, they're not like zones, Zones protect data, keep failures unknown. Sets work within a centre, where VMs reside, Grouping them smartly, side by side. (Pre-Chorus) One rack might falter, with power or cool, So we use domains, it’s a smart rule. Update domains reboot together in sync, Fault domains guard against outages in a blink. (Chorus) Availability sets, group VMs with care, Update and fault domains, they share. Achieving uptime, 99.95, With two or more VMs, they’ll thrive. (Verse 2) In a data centre, sets make the call, To prevent downtime, and keep services for all. Update domains, they handle the reboots, Fault domains step in, when power disputes. (Bridge) Smart grouping is the key, for VMs to stay, In update and fault domains, they find their way. Unplanned downtime? It’s kept at bay, With availability sets, it’s a bright day. (Chorus) Availability sets, group VMs with care, Update and fault domains, they share. Achieving uptime, 99.95, With two or more VMs, they’ll thrive. (Outro) So remember the sets, within the data’s core, With update and fault domains, you’ll get much more. High availability, that’s the Azure way, With smart VM grouping, every day!
