Why I Chose Azure SQL Managed Instance Over Azure SQL Database
A practitioner case study describing a production migration from on-premises SQL Server to Azure. The team migrated a ~200 GB production database used by three backend services and with 25+ SQL Server Agent jobs. The author chose Azure SQL Managed Instance (MI) over Azure SQL Database because MI supported a native .bak restore, preserved SQL Agent jobs, provided instance-scoped economics for multiple databases, offered Resource Governor for workload isolation, and is private-by-default via VNet deployment. Trade-offs accepted included longer provisioning lead times, phased DR/HA decisions, and General Purpose IO characteristics that required query tuning and capacity monitoring. The article presents a decision framework emphasising migration mechanism, Agent job count, workload shape, and need for co-located workload isolation.
Practical, reproducible migration case study that informs cloud database selection for legacy SQL Server workloads; useful to practitioners but not industry-shifting.

Key Takeaways & Evidence Grounding
- Migrated a single production SQL Server database of approximately 200 GB from on-premises to Azure.
- The database supported three backend services and more than 25 SQL Server Agent jobs.
- Only Azure SQL Managed Instance supports native .bak restore (RESTORE DATABASE ... FROM URL); Azure SQL Database does not accept .bak files.
- SQL Managed Instance supports Resource Governor for workload isolation and deploys inside a VNet with a private IP by default; Azure SQL Database requires adding private endpoints to be private.
- The team provisioned a General Purpose Managed Instance sized at 6 vCores and 256 GB storage and accepted longer provisioning times (hours) and phased DR investments.

Practical Guide: Azure PostgreSQL Migration and Tuning
A hands-on tutorial describing how the author completed the Microsoft Applied Skills assessment to configure and migrate to Azure Database for PostgreSQL Flexible Server. The post covers security and monitoring setup (Entra ID authentication, private endpoints, diagnostic settings), restoring an adventureworks sample database with a non-fatal PostgreSQL B-tree index row-size error, creating a cross-region read replica in Canada Central for a primary in Canada East, and query performance tuning using EXPLAIN and targeted index creation.
When SQL Isn't Right: Cosmos DB vs Blob Storage
This technical blog post explains when relational SQL databases are the wrong fit and outlines two Azure alternatives: Azure Cosmos DB for flexible JSON documents and Azure Blob Storage for unstructured files. It describes Cosmos DB concepts (account, database, container, item), emphasizes the critical importance of choosing an appropriate partition key, and explains billing via Request Units with provisioned and serverless modes. For Blob Storage the article covers blob types (block, append, page), storage tiers (Hot, Cool, Archive), and Shared Access Signatures (SAS) for scoped temporary access. The author contrasts Azure SQL, Cosmos DB and Blob Storage and offers practical guidance for matching data shape and access patterns to the right Azure service.
Cloud Database Migration: Hidden Downtime Risks
This technical guide outlines risks that follow cloud database migrations—especially a form of slow operational decay the author calls “hidden downtime.” The piece explains that configuration drift across primary, standby and DR database instances (mismatched patch levels, TZ files, parameters, IAM policies, and telemetry agents) can leave failover targets unusable when a real outage occurs. The author recommends rigorous baseline benchmarking (versions, Maximum Tolerable Downtime), continuous mock failover drills, and automated migration-validation pipelines. It argues managed, automated services that orchestrate version parity, replication catch-up, and coordinated multi-environment patching reduce post-cutover risk. The article highlights Oracle Cloud Infrastructure (OCI) migration options (GoldenGate, Data Migration Service, logical exports) and mentions Nabhaas’ managed delivery services as an example provider that helps maintain operational parity after migration.
