The subsequent main launch of Azure Container Storage delivers as much as 7 occasions increased IOPS and 4 occasions much less latency in comparison with earlier variations.
Extra firms than ever earlier than are selecting to run stateful workloads—similar to relational databases, AI inferencing, and messaging queues—on Kubernetes. For builders constructing on Kubernetes, storage efficiency has by no means been extra essential.
Immediately, we’re asserting the subsequent main launch of Azure Container Storage – v2.0.0. In comparison with prior variations, it delivers as much as 7 occasions increased IOPS, 4 occasions much less latency, and improved useful resource effectivity. With built-in help for native NVMe drives, Azure Container Storage now delivers our quickest, strongest Kubernetes storage platform on Azure. It’s now additionally utterly free to make use of, and accessible as an open-source model for set up on non-AKS clusters. Whether or not you’re working stateful functions in manufacturing, scaling AI workloads, or streamlining dev/check environments, this main launch’s efficiency will give your workloads a substantial increase.
What’s Azure Container Storage?
Earlier than we dive into the most recent enhancements, let’s take a second to revisit what Azure Container Storage is and the way builders run stateful workloads on Kubernetes with velocity, simplicity, and reliability.
Azure Container Storage is a cloud-native quantity administration and orchestration service particularly designed for Kubernetes. It integrates seamlessly with AKS (Azure Kubernetes Service) to allow provisioning of persistent volumes for production-scale, stateful workloads.
Azure Container Storage’s imaginative and prescient is to function the unified block storage orchestrator for Kubernetes workloads on Azure, offering a constant expertise throughout a number of storage backends for simplified quantity orchestration through Kubernetes APIs. This v2.0.0 launch focuses particularly on breakthrough efficiency with native NVMe storage, bringing enterprise-grade efficiency with cloud-native simplicity. Later this yr, we’ll be debuting help for Azure Container Storage to combine with Elastic SAN.
Azure Container Storage delivers optimized efficiency and effectivity with low-latency storage for prime throughput stateful functions, together with built-in orchestration and automation that permits Kubernetes to handle storage swimming pools, persistent quantity lifecycles, snapshots, and scaling—all with out switching contexts or managing particular person CSI (container storage interface) drivers.
What’s new?
There’s fairly a bit to unpack right here, so let’s take a deeper dive into a number of the key advantages that Azure Container Storage v2.0.0 delivers:
Pricing modifications
As earlier than, you’ll proceed to pay for the underlying storage backend you employ. However Azure Container Storage variations 2.0.0 and past will not cost a per-GB month-to-month charge for storage swimming pools bigger than 5 TiB for each our first occasion managed and open-source model, making the service now utterly free to make use of. Provision as a lot storage as you want with out worrying about extra administration charges. This implies you get enterprise-grade storage orchestration and breakthrough efficiency with none extra service prices—simply pure worth on your Kubernetes workloads.
Enhanced efficiency with lowered useful resource consumption
This launch of Azure Container Storage is optimized particularly for native NVMe drives supplied with a wide range of VM households. This focus unlocks the quickest doable I/O efficiency on your most demanding workloads whereas lowering infrastructure prices.
Maybe most fun, this newest model of Azure Container Storage on native NVMe is now quicker than ever earlier than. We’ve rebuilt our structure from the bottom up—from the kernel stage to the management aircraft—to push the bounds of our storage orchestrator. This dramatic velocity enchancment comes with an equally spectacular discount in cluster useful resource consumption. Beforehand, Azure Container Storage on native NVMe had three efficiency modes that might eat 12.5%, 25%, or 50% of your node pool’s CPU cores. Azure Container Storage v2.0.0 not has efficiency tiers. As an alternative, it delivers superior efficiency whereas utilizing fewer sources than even our earlier lowest-impact setting. This interprets on to value financial savings—you get higher efficiency whereas liberating up CPU capability on your functions to carry out even quicker.
Let’s have a look at the benchmarks. On fio (Versatile I/O Tester), the open-source trade normal for storage testing, Azure Container Storage on NVMe delivers roughly 7 occasions increased IOPS and 4 occasions much less latency in comparison with the earlier model.
However how does this translate to actual workloads? We examined our personal PostgreSQL for AKS deployment information and located that PostgreSQL’s transactions per second improved by 60% whereas slicing latency by over 30%. For database-driven functions, this implies quicker question responses, increased throughput, and higher consumer experiences.


All in all, Azure Container Storage delivers a big efficiency increase for I/O-demanding workloads out of the field with out extra configuration wanted, providing builders a easy but highly effective instrument of their cloud-native arsenal.
Accelerated AI mannequin loading and KAITO Integration
For AI and machine studying workloads, mannequin loading time generally is a important bottleneck. Azure VMs outfitted with GPUs have native NVMe drives accessible. With the most recent NVMe enhancements within the new v2.0.0 model, Azure Container Storage takes benefit of this {hardware} by dramatically accelerating mannequin file loading for AI inferencing workloads. With our latest integration with KAITO, the primary Kubernetes-native controller for automating AI mannequin deployment, now you can deploy and scale AI fashions quicker than ever, lowering time-to-inference and bettering total AI utility responsiveness.

We loaded Llama-3.1-8B-Instruct LLM and located a 5 occasions enchancment in mannequin file loading velocity with Azure Container Storage v2.0.0, in comparison with utilizing an ephemeral OS disk.

Extra versatile scaling choices
Azure Container Storage beforehand required a minimal of three nodes when utilizing ephemeral drives. It now works with clusters of any dimension, together with single-node deployments. This flexibility is especially beneficial for functions with strong built-in replication or backup capabilities, improvement environments, and edge deployments the place you want high-performance storage with out the overhead of bigger clusters. The elimination of minimal node necessities additionally reduces prices for smaller deployments whereas sustaining the identical high-performance capabilities.
Open supply and group help
We acknowledge how essential the open-source group is to the well being and spirit of the Kubernetes ecosystem. Azure Container Storage model 2.0.0 is now constructed on our newly created open-source repositories, making it accessible to the broader Kubernetes group.
Whether or not you want the Azure-managed model for seamless AKS integration or want the group open-source model for self-hosted Kubernetes clusters, you get the identical nice product and options. The open-source strategy additionally means simpler set up, better transparency, and the flexibility to contribute to the challenge’s evolution.
