We are pleased to announce that the Azure VMSS Zonal Expansion
feature is now generally available. This significant enhancement allows
customers to transition their virtual machine scale sets from a regional to
zonal resiliency strategy or add additional zones to a scale set. By
distributing VMs across multiple zones, customers can significantly enhance
their business continuity and resilience, achieving a higher availability
Service Level Agreement (SLA) of 99.99% compared to the previous 99.95%.
The Azure VMSS Zonal Expansion feature simplifies the
migration process, enabling customers to update their scale set environment to
the Azure recommended zone-redundant availability strategy without the need to
delete and recreate instances or experience application downtime. This means
that businesses can now take full advantage of the improved availability and
reliability offered by Azure availability zones, ensuring their applications
remain highly available and resilient to potential disruptions.
