Embrace the future of container native storage with Azure Container Storage

Illustrated image

We are thrilled to announce the general availability of Microsoft Azure Container Storage, the industry’s first platform-managed container native storage service in the public cloud. With Kubernetes driving cloud evolution, we are witnessing a transformative shift as enterprises move from virtual machines (VMs) to containers, optimizing for scalability, flexibility, and cost efficiency. We introduce Azure Container Storage to meet these demands, providing best in class price performance for hosting stateful containers on cloud-based storage and delivering lowest latency on locally attached storage.

Azure Container Storage joins our suite of container services, tightly integrating with Kubernetes and simplifying stateful workload management across Azure’s set of comprehensive storage offerings. Previously, customers needed to retrofit stateful workloads to VM-centric storage options with scalability constraints or deploy self-managed open-source container storage solutions. Since Azure Container Storage is built purposefully for Azure Kubernetes Service (AKS), it simplifies the process, allowing developers to focus on innovating and running applications without worrying about managing storage. With the ability to perform all storage operations directly through Kubernetes APIs—such as creating persistent volumes and scaling up capacity on demand, it eliminates the need to interact with control plane APIs of the underlying infrastructure.

Azure Container Storage also streamlines storage management across multiple backing storage options. With its general availability, Azure Container Storage supports Ephemeral Disks (local NVMe and temp SSD) and Azure Disks, just the start in our journey to transform the container storage landscape. Ephemeral Disks support marks a pivotal moment for container users, providing the most comprehensive volume management support for containers on local storage in the cloud. Beyond basic persistent volume (PV) provisioning, Azure Container Storage offers built-in capabilities such as snapshots and autoscaling, capabilities that cannot be found outside of Azure.  

During preview, customers have already begun taking advantage of Azure Container Storage to evolve their business-critical, next-generation solutions. Whether it be optimizing Redpanda cluster performance on Ephemeral Disks or scaling past existing persistent volume limits for Postgres workloads on Azure Disks, Azure Container Storage supports a wide range of workloads. For building stateful applications operating containers, this is just the beginning. Shortly after general availability, we will expand our offerings to include Elastic SAN and later, options like Azure Blobs and Azure Files for shared storage use cases.  

A cloud native solution for all use cases

Azure Container Storage ensures essential resiliency and security for every workload through built-in resiliency design and security enforcements. 

Modernizing existing applications

For any enterprise looking to modernize its applications, Azure Container Storage consolidates management across familiar block storage offerings, simplifies the movement of workloads, and provides continuity in backup and disaster recovery.  

We streamline and consolidate the management experience across our comprehensive portfolio of familiar Azure block storage offerings. Rather than needing to certify and manage multiple container orchestration solutions for each storage resource you deploy, Azure Container Storage efficiently coordinates volume provisioning within a storage pool, a concept we introduce to group storage resources into a unified resource for your AKS cluster. This storage pool can be backed by your preferred storage option, empowering you to choose the most cost-efficient resource tailored to your specific workload performance requirements. For example, Ephemeral Disk, newly introduced as a supported block storage offering for containers, is well-suited for latency-sensitive workloads that benefit from local NVMe or temp SSD storage. KPN, a Dutch telecommunications company, shared their positive experience using Azure Container Storage with local NVMe to host a mail solution on AKS: 

“With Azure Container Storage, we have been able to achieve improved performance in our KPN consumer mail workload by leveraging ephemeral disks and taking advantage of the pooling of resources that Azure Container Storage enables. Instead of the manual configuration of storage, we can focus on running our workloads, and Azure Container Storage will take care of auto-discovering and formatting the NVMe disks, making it simple to use and in line with the Kubernetes way.” 

—Peter Teeninga, Cloud Architect, Personal Cloud by KPN

To make your journey to the cloud as painless as possible we partnered with CloudCasa, a key player in Kubernetes data mobility, to simplify mission-critical migration to the cloud. To continue supporting your cloud estate, we partnered with Kasten, the leading service for data protection for Kubernetes, offering robust backup and disaster recovery capabilities. For more details on our data migration and backup experience provided through our partners, please refer to the later section. 

Building cloud native applications

For application developers building solutions in the cloud, Azure Container Storage offers seamless integration with Kubernetes, providing a container-native experience designed for scalability from the ground up. This ensures that your applications can grow easily and cost-efficiently over time. By supporting industry-standard protocols, such as NVMe-of and iSCSI, we simplify interoperability, providing additional performance options. For instance, you can take advantage of the lower persistent volume attach and detach latencies these protocols offer and achieve rapid scale-out and fast failover. Azure Container Storage allows customers to attach more storage resources to a single VM, increasing the limit to 75 volumes for any VM sizes. The added flexibility increases customers’ ability to optimize Azure resources to meet their cost and performance goals. Sesam, a Norwegian data synchronization and management company, has effectively leveraged this capability to reduce costs by scaling up their persistent volumes more efficiently: 

Azure Container Storage (ACS) has enabled us to achieve lower total cost of ownership in our workload. We have a large number of pods that need their own persistent volumes, and through the use of Azure Disks and storage pool resource pooling, we are able to fulfill this in a more cost-effective manner, without hitting the limits on the number of disks that can be attached to a node. In practice this makes us able to allocate capacity more easily and more efficiently.”

—Geir Ove Grønmo, Product Manager, Sesam.io 

Data migration and backup support through our trusted partners

Highly efficient and operational storage management is the baseline experience Azure Container Storage strives for. Azure Container Storage tightly integrates with two key third-party solutions—CloudCasa and Kasten—to offer you an integrated migrate, backup, and disaster recovery experience for workloads hosted on stateful containers.  

With the ability to automatically recreate an entire cluster, CloudCasa centralizes the management of cluster recovery and migration, making it easy to move your existing Kubernetes workloads to and within AKS. To modernize your existing workloads on Azure, simply do a full backup of the existing storage resources then set up a restore, indicating Azure Container Storage as the new storage resource for your cluster. 

With Azure Container Storage, Microsoft has removed much of the management burden from Kubernetes storage, allowing development and DevOps teams to focus on their data and applications. This approach enables organizations to more easily operate stateful production applications at scale. We are pleased to have worked with the Azure Container Storage team to certify CloudCasa for backup and recovery of stateful applications running on it, and to provide a jointly tested solution for easy migration to it.”
