Container storage is an essential factor of consideration for users who deal with cloud workloads. Complex workloads often need persistent storage mechanisms or platforms to ensure continued and balanced operations. Since there are many methods to provide persistent container storage, users and administrators must choose a platform that is ideal for their needs – Kubernetes is such a platform. 

Kubernetes Overview

Kubernetes, fondly known as k8s, is an open source container orchestration system that helps in the automation of application deployment, scaling, & management across a machine cluster. It manages containerized workloads and has a vast, fast-growing ecosystem. Kubernetes, as a container orchestration platform, is built from a few core concepts merged to form greater functionalities – they are API Server, controllers, pods, and nodes.

The flexibility of cloud-hosted containers, allowing the easy integration of cloud providers’ services, is a prominent incentive for enterprises who prefer an ‘as-a-service’ model over traditional IT infrastructure. Regardless of the way in which cluster nodes are deployed, the Kubernetes control plane provides several methods to link persistent volumes and file shares – which includes the ones created by cloud storage services.

Container Storage with Kubernetes

Because of the wide range of flexibility and support offered by Kubernetes, container storage with the platform can be confusing. However, such storage is straightforward in reality and only consists of the connection of a pod to an external volume. Examples of these volumes are a logical disk and mount point, network file share, cloud file service, or block storage service. The volume type used can determine the nature of the directory, the supporting medium, and its contents.

With Kubernetes, users often use persistent storage volumes with the help of a feature called StatefulSets. It is an API managing pod deployment and scaling, providing unique identities, fixed host names, and automated and ordered rolling code updates. Even if individual pods in the API fails, the persistent pod identifiers match existing volumes to the replacement pods. Furthermore, container-run applications can also link to external databases.

Ensuring Stable Container Environments

Kubernetes is evolving in terms of persistent container storage, networking practices, and better orchestration. VEXXHOST is Kubernetes certified and offers fully managed deployments with seamless integration, constant monitoring, and security. Additionally, our cloud services are based on OpenStack, making the environments free from licensing fees or vendor lock-ins. For many of our clients, private clouds are the preferred choice because of their highly scalable and secure nature.  

Speaking of private clouds, you can now run on a fully agile and customized cloud from VEXXHOST, with no licensing fees and smooth 2-week migration. In fact, we’re ready to put our money where our mouth is. We’re so confident in being able to save you at least 20% or more on your current cloud infrastructure expenditure that if proven wrong- we’ll give you $1,000 credit to our public cloud.
