The adoption of cloud-native, container-based architectures and application modernization continues to fuel demand for persistent storage on Kubernetes platforms. Organizations understand that the benefits of cloud-native workloads in terms of performance, scalability, and portability are key enablers to achieving business goals.
Many enterprises already run cloud-native workloads and understand the benefits of more agile and flexible architectures, including application portability that enables frictionless workload movement from the data center to the cloud, and even across clouds. This provides greater flexibility and responsiveness to business requirements than using legacy technologies.
Data storage solutions for Kubernetes environments have evolved since our last report, especially in the realm of migration and mobility, as well as in maturing enterprise features for security, advanced data services, and enhanced developer experience.
A common pattern in adopting persistent storage solutions for Kubernetes is the reuse of existing enterprise storage solutions. This is usually considered a safe bet for the first couple of deployments, but these systems weren’t architected with the ephemeral nature of containers in mind. Often, older arrays can’t cope with the sheer number of backend operations required by Kubernetes at scale. However, vendors are quickly removing bottlenecks from their architectures to support containers at scale and stretching their product portfolio to include cloud storage services for multicloud use cases.
Compared to other types of storage systems, enterprise storage is highly scalable and secure, aiming to satisfy even the strictest requirements. Often, these systems are operated by trained storage administrators. However, this has been slowly shifting to a self-service on-demand model, with developers requiring more direct access to storage operations to deploy and manage storage for their applications. This is a major boon for enterprise IT organizations looking for the smartest way to evolve their processes and align them with the latest business and technology requirements.
Organizations can now consider more factors than ever before, including financial and business issues, when choosing where their applications and data should run—and they want the freedom to decide where that should be. The public cloud is known for its flexibility and agility, but on-premises infrastructure is still better in terms of efficiency, cost, and reliability. With widespread adoption across cloud, edge, and on-premises, Kubernetes is instrumental in executing the vision of portable, flexible, and agile hybrid cloud strategies, making applications and their data portable and cloud-agnostic—for the most part. It needs the right integration with infrastructure layers—such as storage—to complement its still maturing native support for stateful data storage.
It’s still a significant task to select and implement a Kubernetes storage solution for persistent data that makes the most of Kubernetes’s application mobility and data portability capabilities.
With Kubernetes now supporting business-critical applications and services, requirements become more stringent. Scalability, performance, resilience, security, and other non-functional requirements are the order of the day, and Kubernetes needs to do it all to ensure a consistent level of throughput without service disruptions. These requirements drive the demand for enterprise-class stateful data services, solid security controls, mature multitenant performance management—like quality of service (QoS) and bandwidth throttling—and thorough alerting, reporting, and monitoring.
Lastly, enterprises do not want to be locked into any single vendor’s ecosystem as they reap the benefits of Kubernetes’s portable and agnostic promise, and they’re looking for a storage solution that works with feature parity across on-premises and cloud infrastructures.
This report focuses on persistent enterprise storage solutions for Kubernetes. These enterprise storage solutions support Kubernetes workloads in addition to bare metal and virtualized environments.
