Applications are increasingly built and delivered with containers, across on-premise and cloud footprints. Containers are ephemeral, not permanent — if the process dies or the container is rebooted, all the data for the resident applications are lost. Business-critical applications require that container data remain available beyond the life of the container. The underlying storage layer for containers needs to be highly elastic, easily provisioned by developers and administrators, and, ideally, managed with the Kubernetes container orchestration framework.
Red Hat® OpenShift® Container Storage is flexible, cost-effective, and developer-friendly storage for containers. It helps organizations standardize storage across multiple environments and easily integrates with Red Hat OpenShift to deliver a persistent and foundational storage layer for containerized applications that require long-term storage.
OpenShift Container Storage is the de facto storage technology for Red Hat OpenShift and allows containers to access a persistent, software-defined, and distributed storage system. It provides a permanent place for data to live while containers spin up and down.
OpenShift Container Storage is multiprotocol, working with file, block, and S3 object storage. It is ideal for not only the container application data, but also as the infrastructure underlying the Red Hat OpenShift environment, including storage for Red Hat OpenShift metrics, logging, and registry.
Unlike traditional proprietary storage systems that were not designed with container environments in mind, OpenShift Container Storage can easily run anywhere the OpenShift environment is deployed: bare metal, virtual machines, containers, and cloud deployments. This flexibility helps customers standardize storage across multiple environments. OpenShift Container Storage, when paired with Red Hat OpenShift Container Platform, gives organizations the freedom to build and run applications anywhere with consistent and standardized development, test, and production environments.
FEATURES AND BENEFITS
OpenShift Container Storage enables application portability, allowing customers to make the most of their investment in containers and hybrid cloud technologies. Prominent use cases range from messaging and continuous integration and continuous delivery (CI/CD) applications to persistence for SQL and NoSQL databases and web applications.
|Highly available||Supports critical storage features like mirroring, arbiter volumes, and stretched clusters for high availability and protection of persistent container-based data.|
|Multiprotocol||Supports multiple workloads backed by block, file, and/ or object storage. Multiprotocol support enables the use of OpenShift Container Storage for storage of Red Hat OpenShift metrics, logging, registry, as well as container application data in the environment.|
|Portable||Deploys on bare metal, virtual machines, containers, or in the public cloud. The experience managing storage for a containerized environment remains the same regardless of where it is deployed. OpenShift Container Storage can run anywhere OpenShift Container Platform is deployed.|
|Red Hat OpenShift integration||Installs with Red Hat OpenShift (via Red Hat Ansible®) and is developed, qualified, tested, and versioned coincident with OpenShift Container Platform releases.|
|Highly scalable||Supports up to 1,000 persistent volumes (PVs) per OpenShift Container Storage cluster.|
|Single vendor support model||Support for the entire container-based environment— containers, orchestration, and storage—with a single vendor (Red Hat).|
Most storage infrastructure used by development teams was not developed or optimized for microservices and containers. Development teams need software-defined, container-based storage that is easy to use, highly available, flexible, and allows for faster development cycles for their stateful applications and services. Red Hat OpenShift Container Storage was created specifically for container-based environments and is highly integrated with Red Hat OpenShift Container Platform. Now you can have a single vendor in Red Hat to provide support for the entire container-based environment, including containers, orchestration, and storage.
