This is a historical guide to Azure infrastructure announcements and design commentary reported by Aidan Finn in Petri on November 4, 2020. It covers three regional plans and a broad set of service updates announced or discussed that October; it is not a guide to what Azure offers today.
What did the October 2020 Azure infrastructure roundup cover?
Finn’s roundup combined regional plans, service announcements, and his views on how to design cloud deployments. Its subject matter ranged from storage and networking to virtual machines, backup, app hosting, databases, management, and security. The preview and general-availability labels in the article describe the status reported in 2020, not current availability.
The month’s reported announcements included:
- Storage: Azure NetApp Files manual QoS capacity pools; Azure Disk performance tiers and private-link import and export; Ultra Disk support for 512-sector disks; an expansion of Blob soft-delete preview; and an expansion of the Azure Files premium tier.
- Networking and movement: network analytics updates, resource-move changes, and Private Link-related capabilities.
- Compute: Availability Zone migration, Spot VM features, and expansion of the DCsv2 series.
- Protection and recovery: changes to Azure Backup and Azure Site Recovery.
- App hosting and databases: GitHub Actions, Pv3, and private endpoints for App Service; MySQL Flexible Server preview; and SQL Managed Instance changes.
- Management and security: Azure Monitor, Resource Mover, and cost-management updates, along with Key Vault and Microsoft Sentinel announcements.
This inventory is useful for understanding what Azure was developing and announcing at the time. It should not be used as a feature checklist for a deployment now: the roundup does not establish which capabilities remain available, their current status, or where they are supported.
Which Azure regions were planned in October 2020?
Finn reported Microsoft announcements of three planned data-center regions. These were plans as reported in October 2020; the article does not establish launch dates or present-day status.

| Location named in the 2020 roundup | What the article establishes |
|---|---|
| Greece | A planned Microsoft data-center region announced by October 2020. |
| Austria | A planned Microsoft data-center region announced by October 2020. |
| Taiwan | A planned Microsoft data-center region announced by October 2020. |
The article makes an important distinction: a region is not a single data center. Finn described it as a collection of data centers, and noted that a Microsoft region can support Azure alongside Microsoft 365, Dynamics 365, Xbox, and internal services. That is his explanation from 2020, rather than a substitute for current Microsoft definitions.
How did the article describe regions and availability zones?
In Finn’s 2020 account, availability zones spread deployments across separate physical buildings and dependencies where supported. A region and a zone are therefore different resilience boundaries; neither label by itself tells you whether a particular service, feature, or architecture is available in a specific location.
He also cautioned that recently announced local regions might offer a smaller service selection than the large regions he called “hero regions.” Treat that as a warning about checking service coverage, not as a present-day comparison of particular regions. The article does not supply a region-by-region service matrix.
What infrastructure developments did Finn highlight beyond the monthly list?
Finn pointed to developments from the preceding period in Azure Firewall, Azure Firewall Manager, Secure Virtual Hub, Private Link and Private Endpoint, Blob storage tiering, disk performance burst, and Azure Files premium-tier pricing. These were examples of the breadth and pace of infrastructure work he saw at the time, not a current price list or a quantified comparison. The article does not provide a verified cost-saving figure.

He also suggested that investment associated with the U.S. JEDI cloud contract could benefit Azure users. He explicitly qualified that connection: “I have no hard evidence of what I am writing here.” It is his inference, not an established causal finding.
What design lessons does the article offer?
Finn’s central operational point is that moving to cloud does not remove the need for deliberate architecture. As he put it, “Nope; you still have to learn good practices and design.” Existing applications, legacy systems, and on-premises networks can continue to shape a cloud deployment, especially when virtual machines must communicate with systems that remain in-house.
When assessing an Azure design, his advice can be turned into practical review questions:
- Is the design based on good practices? Identify the reason for unusual choices and whether they create avoidable complexity.
- Will it scale? Consider expected workload growth and what changes when real users, systems, and traffic are introduced.
- What does it depend on? Map connections to existing systems and on-premises networks, including security and private-connectivity needs.
- Does it meet operational needs? Check how the design will be monitored, maintained, migrated, and recovered.
- What must be built or customized? Account for bespoke work and the skills needed to operate it, rather than assuming cloud services remove that burden.
These are professional recommendations, not findings from a controlled study. Their value is as a design-review lens: make dependencies, resilience boundaries, and operational work explicit before choosing services.

What should readers take from this October 2020 edition?
The roundup captures a busy month of Azure infrastructure announcements and a lasting architectural reminder: cloud services still need to fit the workload, its dependencies, and the organization’s operational practices. Its regional plans and service-status labels belong to 2020. Anyone making a current deployment decision should verify present regional coverage, feature status, pricing, and service definitions in Microsoft’s current documentation.
