Microsoft Azure Solutions Architect Expert AZ-305 Practice Question

Azure SQL Database in the Hyperscale service tier is purpose-built for very large and quickly growing databases. Hyperscale supports up to 100 TB of storage that expands automatically as data is inserted, so no manual size-increase operations or data migrations are required. It can provision as many as 30 named read-scale replicas, which can be added or removed in minutes to provide rapid, non-blocking compute scale-out for read-intensive workloads. General Purpose serverless tops out at 4 TB and offers no read replicas. Managed Instance Business Critical provides only a single built-in read-only replica and allows a maximum of 8 TB per database. The Premium tier of single databases is limited to 4 TB (and uses geo-replication primarily for DR, not fast scale-out) and therefore cannot accommodate growth beyond 15 TB. Consequently, Hyperscale is the only option that satisfies both the storage and read-scale requirements.
