kubernetes storage solutions

SSDs, for example, offer better read/write performance than HDDs, while NVMe SSDs are particularly suitable for heavy workloads. These solutions also open up an exciting new opportunity for the Solution Architect as well as solving the cloud, hybrid, multi-cloud and on-premise persistent storage issues in Kubernetes … Read more: Kubernetes Shared Storage: The Basics and a Quick Tutorial. Kubernetes uses clusters to help organizations manage containers at scale. Any of the above solutions can provide reliable storage for your data. Heketi likewise supports any number of GlusterFS clusters, permitting Kubernetes administrators to implement network storage without being constrained to a single GlusterFS cluster. GlusterFS responds and scales more rapidly than its rivals, yet at the same time maintains the convenience of use. Azure Kubernetes Service How-To: Configure Persistent Volumes for Containers in AKSAzure Kubernetes service is being widely used by enterprises to deploy Microservices workloads, both for greenfield as well as brownfield deployments. It is a precisely defined file storage framework that can scale to petabytes, handle a great number of users, and utilize any on-disk filesystem with the backing for different features. As VMware started developing solutions for cloud native technologies we created what we called the vSphere Cloud Provider (VCP) for Kubernetes (previously known as Project Hatchway). Any node failure would affect volume replicas on that particular node only. Read more: Kubernetes NFS: Quick Tutorials. While Kubernetes allows for innovative ways to scale and use containerized workloads, there is still the need for storage solutions. Each StorageClass references a volume plugin, also known as a provisioner. The Kubernetes storage architecture is based on Volumes as a central abstraction. Kubernetes handles all aspects of the container lifecycle, including creation, management, automation, load balancing, and hardware interfaces, as well as interfaces to storage devices. In this article, we will outline and evaluate popular cloud-native storage solutions. It is a host attached storage, where every volume directly maps to the host to which it is attached. This allows users to select from several storage options, without worrying about the underlying implementation of each one. Such a decision depends on an exact understanding of the storage needs of the cluster. The YAML file declares the significant number of variables of what the administrator needs in the cluster. This can lead to stability issues. Learn how ECS compares to Kubernetes and also to a managed Kubernetes service that offers both aspects - Amazon Elastic Kubernetes service. Using Trident, Kubernetes persistent volume claims can be answered by creating highly space-efficient clones of persistent volumes instantaneously. Administrators can define storage resources, together with their performance, capacity and cost parameters, in a PV. Introduction A StorageClass provides a way for administrators to describe the "classes" of storage they offer. Over the years, the Kubernetes community introduced several rich storage features, such as: Persistent Volumes (PV), which provides storage resources for objects in the cluster. Every storage volume deployed in EBS is assigned a control plane, disk manager, and a data plane. The life cycle of PV and PVC is divided into 5 stages. The storage type can be a range of different formats, with support extending to Google Persistent Disk, Amazon EBS, Azure Disk Storage, and others. Storage Efficiency for Improving Kubernetes Cloud Storage CostsWhen Kubernetes’ users provision large amounts of storage for containerized applications, it may be the case that large allocation of storage is never used. Applications often need to be able to store and retrieve data. It is a CSI-compliant block storage solution with bare-metal performance that seamlessly integrates with Kubernetes-native administrative tooling such as Kubectl, … Those issues are avoided when using the second option for provisioning storage in Kubernetes: dynamic provisioning. The cost benefits of using FlexClone are considerable, as no storage needs to be consumed to create the clone: only the changed data needs to be stored. Unlike other storage solutions, data in OpenEBS is replicated across multiple nodes. The PVC can specify some or all of the storage parameters defined in the PV. This offering provides cloud storage to applications running in the cloud, on-prem, and hybrid cloud infrastructures. Storage space can be conserved through data deduplication, compression, compaction, thin provisioning, and automatically tiering cold data to less-expensive object storage on Amazon S3 or Azure Blob until it needs to be used. The container contains all the packages you need to run a service. In dynamic provisioning, persistent volumes are deployed automatically based on the claims the cluster receives. OpenEBS eliminates vendor lock-in issues, which happens due to different implementation of storage architecture by various cloud storage providers. AWS Kubernetes Cluster: Quick Setup with EC2 and EKS, Kubernetes Workloads with Cloud Volumes ONTAP: Success Stories, Container Management in the Cloud Age: New Insights from 451 Research, Using Cloud Manager for Kubernetes Deployment. But the developer license(Portworx essentials), which only allows up to 5 TB of storage and five nodes), is limited for Kubernetes compared to the PX-Enterprise version. One of the many storage plugins offered by Kubernetes is the NFS plugin, which lets containers mount a Kubernetes volume as a local drive. In Kubernetes, you can create a volume plugin for any available SDS solution using Container Storage Interface (CSI) and Flexvolume plugin … But today, a new model is taking precedence: microservices deployment with containerized workloads. Portworx is another container storage solution intended for Kubernetes, with a focus on highly available clusters. OpenEBS can be integrated easily with Kubernetes, which makes it a highly rated cloud-native storage on the CNCF landscape. Likewise, monitoring is also supported by third-party monitoring tools such as Prometheus and Grafana to manage advanced metrics, alerts, and graphs for storage containers. Instead, pods should use Persistent Volumes and Persistent Volume Claims (PV/PVC) to define the storage requirements of their applications. This is useful for migrating legacy applications to Kubernetes, because they can continue accessing data the same way as they did in a traditional deployment model. NFS makes it possible for a single file system to be mounted by multiple hosts who all have concurrent file access. We will start with a quick look at the cloud-native storage tool and why are they needed for Kubernetes. Azure files, Azure Disks, Cloud Volumes ONTAP, etc. Also, Rook provides scaling, security, and resource management of clusters in one place. Robin Cloud Native Storage (CNS) brings advanced data management capabilities to Kubernetes. LocalPV, on the other hand, provides performance for which it comprises advanced features like replication or snapshots. With the rapid growth of Kubernetes among global 2000 enterprises, organizations increasingly face challenges using existing enterprise storage and data protection solutions to support applications running on Kubernetes. A StorageClass is a Kubernetes application programming interface (API) for setting storage parameters. Read more: How to Set Up MySQL Kubernetes Deployments with Cloud Volumes ONTAP. NetApp Solutions; Example Kubernetes StorageClasses for ONTAP AI Deployments PDFs. In this post we take a closer look at the 451 Research report, its findings, and how NetApp’s open-source Trident provisioner project and Cloud Volumes ONTAP fit into this picture. Read more: AWS ECS vs Kubernetes: An Unfair Comparison? Persistent Volume Claims (PVC), on the other hand, are requ… PVs are not portable between Kubernetes clusters. Read more: Kubernetes Dynamic Provisioning with NetApp Trident and Cloud Volumes ONTAP. PV and PVC separate storage implementations from functionality and allow pods to use storage in a portable way. Kubernetes storage takes container deployment to a whole new level by providing a robust solution for managing and scaling containers and containerized applications and workloads across a cluster of machines. In this article, we’ll look at how containerized applications in Kubernetes can take advantage of the enterprise data protection features of Cloud Volumes ONTAP by provisioning persistent volumes through NetApp Trident. Read more: NetApp Trident and Docker Volume Tutorial. They are portable and can be moved together with an application. Enterprises who want performance instead of features on a big scale will go for Portwrox. All of the additional data management tasks associated with the volume from scaling and capacity to monitoring and backup creation are manual operations for the user to carry out. Kubernetes creates permanent storage mechanisms for containers, based on Kubernetes persistent volumes (PV). However, Kubernetes provides several capabilities that help mitigate this problem, and support stateful workloads in a containerized environment. The performance is excellent! Ceph is one incredible example. Traditional volumes to store and retrieve data are created as Kubernetes resources backed by Azure Storage. Read more: How to Use NetApp Cloud Manager with Trident for Provisioning Persistent Volumes in Kubernetes Deployments. You’ll learn some of the ground floor rules of the cluster-building orchestration platform, including its security features, fundamental architecture for load balancing and failure prevention, and more. hbspt.cta._relativeUrls=true;hbspt.cta.load(525875, '92fbd89e-b44f-4a02-a1e9-5ee50fb971d6', {}); [Cloud Volumes ONTAP, DevOps, Kubernetes, Elementary, Kubernetes Storage, 24 minute read, A]. Automated rollouts and rollbacks You can describe the desired state for your deployed containers using Kubernetes, and it can change the actual state to the desired state at a controlled rate. Whether based on-prem or in the cloud, there are a number of basic things to know about Kubernetes for developers that will help make using the service much easier and more effective. Managing Stateful Applications in KubernetesStateful applications that run in Kubernetes need storage that is persistent and with a lifecycle that is independent of pods. It is a dynamic configuration method that creates new volumes on demand. The combination of storage volume management software, the NVMe-oF specification and the CSI standard, enable containerized Kubernetes infrastructures to dynamically and efficiently scale data-intensive containerized workloads on disaggregated storage. Kubernetes uses PV controllers to implement and manage the lifecycle of PV and PVC. So, administrators can check cluster health and the status of resources. These storage challenges can be addressed through the use of the built-in storage efficiency features of Cloud Volumes ONTAP, which are available to Kubernetes users through the NetApp Trident provisioner. Persistent Volumes (PV) are storage units that have been provisioned by an administrator. Should the cluster’s storage demands exceed the number of volumes previously provisioned, there would be an issue. Deploying these storage providers on Kubernetes is also very simple with Rook. Whichever storage type is preferred, the Docker host machine will need to have access to it ahead of when provisioning takes place (an Amazon EC2 instance hosting a Docker container needs an Amazon EBS volume assigned to it). But the CI/CD pipeline also requires an easy way to test new builds and changes to environments. Container Management in the Cloud Age: New Insights from 451 ResearchAccording to a recent 451 Research report “The State of Data Management in the Container Era,” 46% of organizations use public cloud resources as their primary approach to container data storage. This solution can help meet all the data protection requirements of production Kubernetes workloads transparently and with ease. The idea of this storage orchestration tool, according to Rook maintainer Travis Nielsen, is to have storage hosted within the container platform itself, providing the “framework and support for a diverse set of storage solutions to natively integrate with Kubernetes and OpenShift. This blog covers the steps required to provision persistent volumes using Azure disks and attach them to containers in AKS. This eliminates the need for administrators to manually create new storage volumes in their cloud or storage provider, and then create PersistentVolume objects to make them available in the cluster. Kubernetes is the most popular orchestrator for containerized workloads. PersistentVolumeClaim (PVC), which is a request to use a PV. The Cloudian Kubernetes S3 Operator (available now on GitHub) provides an easy way to access exabyte-scalable Cloudian storage from your Kubernetes-based applications. Read more: Cloud File Sharing: Kubernetes NFS Provisioning with Cloud Volumes ONTAP and Trident. OpenEBS is the leading open-source project which offers cloud-native storage solutions for Kubernetes deployments. In 2019 I published a blog: Kubernetes Storage Performance Comparison.My goal was to evaluate the most common storage solutions available for Kubernetes … The issue of storage efficiency is affected by how Kubernetes users decide to provision persistent volumes: manually through static provisioning, or automatically through dynamic provisioning. GlusterFS utilizes block storage (128 kb to be exact), which stores a lot of information in pieces on open space in storage servers. But differences are based on how they handle the stored data. It follows a Container Attached Storage (CAS) architecture. Read more in Container Management in the Cloud Age: New Insights from 451 Research. NetApp’s Trident provisioner works alongside the Cloud Volumes ONTAP data management platform from inside Kubernetes, extending the benefits of storage optimization and ease of use to persistent volumes in Kubernetes. Kubernetes persistent volumes enable a great amount of flexibility when it comes to storage provisioning due to the separation persistent volumes create between the containerized applications and the storage the apps make use of. The data on different nodes continues to be available at the same performance levels, making applications more tolerant to failures. These volumes are accessed through I/O technology and provide auto-tuning based on the I/O protocol used. OpenEBS as well is deployed as a container that enables easy assigning of storage services on a per-application, cluster, or container level. This allows a Kubernetes cluster to provision different types of storage depending on the changing requirements of its workload. Read more: Kubernetes Volume Cloning with Cloud Volumes ONTAP. With Kubernetes dynamic provisioning, users can greatly simplify how persistent volumes are deployed in clusters. Kubernetes persistent volumes are created through the use of a provisioner that interfaces with backend storage through the use of a plugin. The Portworx platform provides High Availability, Data Management, Disaster Recovery, and Data Security for Kubernetes clusters running across clouds. Kubernetes supports dynamic volume provisioning, which allows for creation of storage volumes on demand. This document describes the concept of a StorageClass in Kubernetes. AWS ECS vs Kubernetes: An Unfair Comparison?Amazon Elastic Compute Service (ECS) is a container orchestration service that runs and manages containers. No worries about database container failure or downtimes. Kubernetes provides a range of storage plugins that integrate with storage offered by public cloud providers, virtualization systems like VMware, and on-premise hardware using standard protocols like NFS. Different classes might map to quality-of-service levels, or to backup policies, or to arbitrary policies determined by the cluster administrators. Using commands within Docker, volumes can be created, managed, and used to keep Docker admin operations consistently interfaced. It supports various storage providers, including Cassandra, Ceph, and EdgeFs, which guarantees users can pick storage innovations dependent on their workflows without agonizing over how well these storages integrate with Kubernetes. Kubernetes natively offers some solutions to manage storage: ephemeral options, persistent storage in terms of Persistent Volumes, Persistent Volume Claims, Storage Classes, or StatefulSets. This allows you to retain the use of native Kubernetes manifests and constructs to interact with your persistent storage, while at the same time gaining the benefits of using NetApp’s enterprise-grade data management platform. Kubernetes administrators can define StorageClasses and assign PVs to them. I’ve decided to perform all … Without the requirements to provision volumes manually and have foreknowledge of the storage amount needed, users can let their clusters scale without worry. Monitoring of the Metrics in OpenEBS is easy since containerized volumes are using CAS architecture. In this post, we’ll walk you through the basics of Kubernetes. Portworx is well known for its software-based products specializing in security, storage, and disaster recovery. VCP has been available for a while and is in use by tons of customers. They are independent of any single pod, breaking them free from the ephemeral life cycle of pods. Lower on the list were offerings from established storage-focused companies like Dell EMC, NetApp and Pure Storage. StorPool has native integration with Kubernetes ( introduced in StorPool’s v18.02 release ) through which persistent volumes are provided to … A Kubernetes cluster uses several components to manage container workloads, including an API server, a scheduler, kubelet (an agent that runs on each container), and etcd (a lightweight database that holds cluster configuration). A solution for handling those operations are NetApp’s Trident and Cloud Volumes ONTAP. These platforms also have to deliver enterprise-grade disaster recovery and business continuity solutions. Persistent volumes are mandatory elements of the architecture for stateful data sets used by containers. Initially, Kubernetes had integrated volume plugins to connect to these company’s storage backends. A PV also defines details like routes, IP addresses, credentials, and a lifecycle policy for the data. In easy words, Rook allows putting storage solutions into containers and provides different mechanisms to run those storage containers on Kubernetes efficiently. Google Cloud offers several storage solutions that are specialized for different needs. An application can simply request storage with specific criteria, and Kubernetes provisions it automatically. How to Use NetApp Cloud Manager with Trident for Provisioning Persistent Volumes in Kubernetes DeploymentsNetApp Trident is a fully supported, open-source storage provisioner for Kubernetes, which enables Kubernetes persistent volumes to be dynamically provisioned with Cloud Volumes ONTAP. Rook is another very popular open-source storage solution for Kubernetes, but it differs from others due to its storage orchestrating capacities. Besides these Kubernetes-native features, this post also takes a look at how NetApp Trident and Cloud Volumes ONTAP can be used to make Kubernetes deployment even easier, allowing for persistent volumes to be provisioned dynamically on AWS and Azure storage resources, and to deploy Kubernetes clusters across clouds from a single central management console. As different storage solutions can be used for this, data protection levels can vary. There may also be scenarios where a persistent volume stores data that is not compressed, a storage inefficiency that leads to consuming more storage and raising the associated storage costs unnecessarily. Because containers are ephemeral, they erase all stored data by default, causing major challenges for many types of workloads. That approach helps significantly with scaling the cluster horizontally and reducing access times. Rook. You’ll be able to see specific code examples for provisioning, creating separate storage classes, and more. Those who want to store massive amounts of data and want stability will prefer GlusterFS. There are several storage options for applications running on Google Kubernetes Engine (GKE). By far, the best. Modernize Your Storage. Beyond these, Kubernetes provides storage abstractions which you can use to offer storage to your cluster. It is a production-grade Block and Object Storage which transforms storage volumes into self-scaling storage systems that can heal and manage themselves. Monolith vs. Microservices: How Do You Run Your Applications? It manages cloud machine instances, scales and schedules groups of containers across multiple Availability Zones (AZ). Data Protection for Persistent Data Storage in Kubernetes WorkloadsEnterprise workloads typically have a strong requirement for reliable data storage. Introduction A StorageClass provides a way for administrators to describe the "classes" of storage they offer. Comparing Kubernetes to ECS is not an apples-to-apples comparison, because ECS provides both container orchestration and a managed service that operates it for Amazon users. Persistent Volume is hosted in its own Pod and can remain alive for as long as necessary for ongoing operations. Using persistent volumes can go some way towards achieving this, but another solution is to use stateful sets and dynamic provisioning, which are easier both to scale and to manage. Volumes can be accessed directly from pods or Persistent Volumes (defined below). Monolith vs. Microservices: How Are You Running Your Applications?There has been a revolution going on in the way that software and applications are being developed and deployed. Stateful applications include some business-critical components; a database is a good example of a stateful application that is key to an enterprise and must ensure is protected. These objects are loaded as custom resources in Kubernetes for easy attaching/detaching of storage volumes to pods without restarting them. The Portworx Kubernetes storage solution is trusted in production by leading Global enterprises like Comcast, T-Mobile, Ford and more. They can support any type of storage infrastructure, including local storage devices, NFS and cloud storage services. Stateful sets are good for horizontal-scaling systems that would use a new node while deploying persistent storage from a template. It also integrates well with Amazon EBS, Google PD, and Azure Block Storage to focus more on the management of your essential data, not its underlying storage infrastructure. PX-secure in PX-enterprise provides secure, manged-key encryption for container volumes that seamlessly integrates with well known key management frameworks like AWS KMS and Hashicorp Vault. It is crucial to define a starting point so you can start experimenting with your storage-based container application and find your perfect solution. Trident does this using a set of basic annotations on the persistent volume claim, and works in tandem with the ONTAP back-end systems to locate the original volume claim and recreating it. One of these advantages is that it offers more flexibility than block-level persistent volume allocations. Built on the S3 API, Cloudian lets you dynamically or statically provision object storage with this lightweight Operator using S3 APIs. Storage can be referenced directly from within a pod, but this violates the pod’s portability principles and is not recommended. OpenEBS CAS architecture also allows instantaneous snapshots that are created and managed using the standard kubectl command. With static provisioning, admins provision persistent volumes for the cluster ahead of time. Coming to the data plane, users can pick various data planes for different application workflows depending upon their configuration. Familiarity with volumes and persistent volumes is suggested. Storage has always been a challenge for IT practitioners, with issues like integrity, retention, replication and migration of large data sets. Lastly, who wants more customizations for their workloads will want to settle for OpenEBS. A Storage engine optimizes that given workflow either with a precise set of features or performance. Storage can also be defined as a data service, commonly a database. Cloud Manager simplifies the process of deploying NetApp Trident into your Kubernetes deployment, irrespective of its underlying implementation, and then configuring the cluster to use a specific deployment of Cloud Volumes ONTAP. Performance and data protection is HAS(host-attached storage) type, yet containerized utilizing Kubernetes and other container management platforms. Kubernetes for Developers: Overview, Insights, and TipsKubernetes has transformed the way that companies design, deploy, and orchestrate microservices. With NFS, users can share files in enterprise-scale deployments with thousands of users around the world concurrently for use cases as diverse as big data analytics, data lake creation, archiving, database, and more. Read more about the added values of Cloud Volumes ONTAP in Kubernetes: Read more in our series of guides about Kubernetes storage. Normally, this would require provisioning an entirely new persistent volume with all of the same data. In simple words, To make the data available when cluster restarts, there is a need for storage solution or mechanism which manages data operation for the cluster. At the same time, the Node Disk Manager(NDM) provides easy access to a list of node’s attached disks in the form of Block Device objects. GlusterFS also utilizes industry-standard conventions like SMB and NFS for networked file systems, supports replication, cloning, and bitrot identification for detecting data corruption. By deploying Kubernetes with NetApp Trident, the storage used for persistent volumes is allocated by NetApp systems such as Cloud Volumes ONTAP, which come with multiple data protection benefits: backup and restore for databases of any size through ONTAP Snapshots, high availability for Kubernetes persistent volumes across AZs with Cloud Volumes ONTAP HA, efficient, block-level data replication with SnapMirror, and FlexClone data cloning for fast, space-efficient clones to benefit DevOps testing. Kubernetes provides no native storage for log data, but one can integrate many existing logging solutions into the Kubernetes cluster. A PVC, on the other hand, is used by users or developers to describe the storage required by the application. Kubernetes Volume Cloning with Cloud Volumes ONTAPDevelopers get a huge advantage from Kubernetes’ abilities to easily scale and manage containerized workloads. ... Turnkey Cloud Solutions. Unlike any other storage options. A volumerepresents a way to store, retrieve, and persist data across pods and through the application lifecycle. Kubernetes: Provisioning Persistent VolumesWhile Kubernetes allows for innovative ways to scale and use containerized workloads, there is still the need for storage solutions. Cloud Volumes ONTAP provides a whole host of features that are crucial for the reliable storage of persistent data. Learn how Kubernetes storage works, including volumes, persistent volumes, static and dynamic provisioning, and see how to set up a storage volume in a Kubernetes YAML file. That means Storage mechanisms need to be deployed externally on various hosts based on the needs, and these volumes may need to be scaled on the fly as the usage goes up. Read more: Data Protection for Persistent Data Storage in Kubernetes Workloads. Creating a PV is similar to creating a storage resource object in Kubernetes. Kubernetes also supports a variety of persistent storage models, including files, block storage, object storage, and cloud services belonging to these and additional categories. Trident and Cloud Volumes ONTAP offer a better solution: FlexClone® data clone volumes. Each StorageClass represents a type of storage—for example, fast SSD storage vs regular magnetic drives or remote cloud storage. Developers will many times estimate for too large a storage need. Ways to provide both long-term and temporary storage to Pods in your cluster. It also separates users and applications from storage configuration requirements. How does native Kubernetes handle storage? This whole process happens automatically when a specific storage type is requested by users. Portworx allows you to run containerized applications with highly-availability (HA) across all your nodes, containers, cloud instances, and data centers. It has a dedicated dashboard for storage Clusters. Parameters like volume throughput, latency, and data patterns are easily manageable and trackable through Kube-Dashboard and projects like Prometheus, FluentD, Grafana, etc. Kubernetes NFS: Quick TutorialsKubernetes Volumes are storage units that allow containers in a Kubernetes cluster to write, read and share data. In either case, the challenge is to make sure there is storage efficiency. And while Kubernetes makes container usage easier, managing the persistent storage requirements for stateful sets can present challenges when it comes to data protection, ensuring high availability, and rising storage costs—all of which Cloud Volumes ONTAP can help solve.
