summary (300 characters): Discover how Microsoft Azure Kubernetes Service (AKS) empowers high-performance PostgreSQL deployments with cutting-edge storage options like local NVMe via Azure Container Storage and Premium SSD v Achieve low latency, scalable throughput, and high availability with CloudNativePG operator for mission-critical workloads. Unique bullet points in HTML:
Running High-Performance PostgreSQL on Azure Kubernetes Service
PostgreSQL is rapidly becoming the go-to database for Kubernetes workloads. According to the Kubernetes in the Wild 2025 report, it now powers 36% of all database workloads on Kubernetes—up 6 points since 202 This surge highlights PostgreSQL’s growing trust and popularity in the cloud-native world.
What’s New: Simplified Stateful PostgreSQL Deployments on AKS
Running data-heavy PostgreSQL workloads on Kubernetes can be tricky. Managing StatefulSets, replication, and storage settings often feels complex. Fortunately, Microsoft Azure now offers two streamlined options tailored to your performance needs:
- Azure Container Storage uses local NVMe drives to deliver ultra-low latency and high IOPS for demanding workloads.
- Premium SSD v2 balances price and performance, perfect for scalable production environments.
Plus, Azure integrates the open-source CloudNativePG operator to support high availability and automated failover for PostgreSQL on AKS. This combo makes AKS a powerhouse for stateful workloads.
Major Updates: Breakthrough Performance with Local NVMe
Local NVMe storage directly attached to Azure VMs used to require complex manual setups. Now, Azure Container Storage dynamically provisions Kubernetes volumes backed by local NVMe drives on AKS nodes. This means PostgreSQL can reach up to 26,000 transactions per second (TPS) with single-digit millisecond latency on larger VMs.
“Azure Container Storage gives PostgreSQL users direct attach block storage IOPS and latency within a managed, orchestrated cloud environment.”
This setup is ideal for latency-sensitive applications like payment systems, gaming backends, or real-time personalization engines. Additionally, Azure Container Storage supports Azure Disk and Elastic SAN, so you can switch storage types without changing your Kubernetes control plane.
Optimizing Cost and Performance with Premium SSD v2
Not every workload needs the extreme speed of local NVMe. Premium SSD v2 offers flexible scaling of IOPS, throughput, and size independently. This flexibility avoids overprovisioning and cuts costs for multi-tenant SaaS or spiky traffic applications.
With up to 80,000 IOPS and 1,200 MB/s per volume, Premium SSD v2 handles demanding PostgreSQL workloads while adapting to your app’s growth.
“Premium SSD v2 leads to real savings without sacrificing performance.”
Choosing Between Local NVMe and Premium SSD v2
Benchmarks show local NVMe on Standard_L16s_v3 VMs delivers about 14,800 TPS with 4.3 ms latency. Premium SSD v2 on Standard_D16ds_v5 hits 8,600 TPS with 7.4 ms latency. Local NVMe offers superior speed but at a higher cost and less flexibility. Premium SSD v2 provides better price-performance and scalability.
For data durability, Premium SSD v2 offers built-in redundancy. Local NVMe requires a replica-based architecture via CloudNativePG and backups to object storage.
High Availability Made Easy with CloudNativePG on AKS
Deploying PostgreSQL in production demands high availability and reliable backups. The CloudNativePG operator simplifies this by providing:
- Built-in replication and automated failover
- Application-consistent backups integrated with Azure Blob Storage
- Seamless Azure Container Storage support
- Flexible storage choices between Premium SSD v2 and local NVMe
This hands-off approach lets teams focus on their apps, not on building complex HA logic.
Looking Ahead: AKS for Stateful Workloads Beyond PostgreSQL
PostgreSQL is just the start. AKS is evolving to support Redis, MongoDB, Kafka, and AI inferencing with GPU-backed nodes. Innovations like Azure Container Storage and Premium SSD v2 make running stateful apps reliable, performant, and cost-effective.
Modernize your data layer on Kubernetes today. Azure’s proven patterns and tools deliver the performance and manageability your mission-critical workloads deserve.
