public or private cloud environments. CloudStack allows you to easily deploy Kubernetes clusters into your own infrastructure without worrying about the underlying infrastructure and removing the coupling to specific virtualization platforms. It also allows easy deployment of Kubernetes as a Service (KaaS) offerings.</p><p class="px18">Host your Kubernetes clusters on it to simplify your work and ensure consistent and predictable behavior of your applications, no matter the underlying infrastructure.</p><p class="px18">CloudStack provides a Kubernetes Cluster API Provider and also the CloudStack Kubernetes Service - giving a choice of integration techniques.</p><p class="px18">CloudStack is in widespread production usage at many of the world’s largest organizations including many Fortune 500 companies. It includes the entire “stack” of features you need: compute orchestration, Network-as-a-Service, user and account management, a complete and open native API, resource accounting, and a first-class User Interface.</p></div><div class="col-lg-6 margin-second text-center"><a href="https://docs.google.com/forms/d/e/1FAIpQLScPHIRetdt-pxPT62IesXMoQUmhQ8ATGKcYZa507mB9uwzn-Q/viewform" target="_blank"><img src="/img/CloudStack_survey2.png" class="img-fluid" alt="CloudStack survey"></a></div></div></div></section><section class="bgr-gray"><div class="container"><div class="row"><div class="col-lg-6"><div class="section-title">Explore the Kubernetes Cluster API Provider for Apache CloudStack</div><p class="px18 mt-4">The Kubernetes Cluster API (CAPI) provider for Apache CloudStack allows Ku- bernetes users to build and manage resources on Apache CloudStack. The pro- vider is available under the Apache 2 open-source license and is managed by the Cloud Native Computing Foundation (CNCF). The Cluster API brings declara- tive, Kubernetes-style APIs to cluster creation, configuration and management. The API itself is shared across multiple cloud providers allowing for true Apache CloudStack hybrid deployments of Kubernetes. It is built atop the lessons learned from previous cluster managers such as kops and kubicorn.</p></div><div class="col-lg-6"><iframe width="100%" height="315" src="https://www.youtube.com/embed/NcfVkVT48Kk" title="Bootstrapping K8S Cluster using CAPC - Apache CloudStack - Kubernetes" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen=""></iframe></div></div></div></section><div class="container"><section class="dark-blue p-5 right-banner"><div class="row"><div class="col-lg-7"><h2 class="section-title">Launching a Kubernetes cluster on Apache CloudStack</h2><p class="px18 mt-4">If users want to launch a Kubernetes cluster on Apache Cloudstack, they can check out the Getting Started Guide to create your first Kubernetes cluster on Apache CloudStack using Cluster API.</p><p class="px18 mb-4">CloudStack hybrid deployments of Kubernetes.

It gives users the ability to create Kubernetes clusters within an existing multi-tenant environment provided by CloudStack.

When a node fails, or resources are insufficient, or the services are unavailable, a new node is provisioned and added to the cluster. In this case, Kubernetes will reschedule the podes from failed nodes.</p></div></div></div><div role="tabpanel" class="tabItem_Ymn6" hidden=""><div class="row p-4"><div class="col-lg-2 text-center"><img src="/img/multi-cluster_icon.svg" alt="Multiple Cluster Management" class="mb-4"></div><div class="col-lg-10"><p class="px18">When Kubernetes cluster expansion is considered, ClusterAPI provides support for a range of different providers, including Apache CloudStack. This ClusterAPI capability is important for companies that use heterogeneous providers from different service providers.</p><p class="px18">The ClusterAPI abstracts away the different deployment mechanisms that are offered by various providers and infrastructure vendors, allowing operators to fully standardize the entire deployment, regardless of vendor or datacenter or edge. As a result, operators have more control over the entire application environment in a standardized approach to cluster lifecycle management, enabling reuse of existing components across multiple clusters, thus reducing rework.</p></div></div></div><div role="tabpanel" class="tabItem_Ymn6" hidden=""><div class="row p-4"><div class="col-lg-2 text-center"><img src="/img/scaling_icon.svg" alt="Scaling" class="mb-4"></div><div class="col-lg-10"><p class="px18">Application workload is often unpredictable, and to scale up and down Kubernetes clusters, the ClusterAPI facilitates scaling when workloads change. The main task of the ClusterAPI is to ensure that there is enough capacity to meet the current demand for access to the application, also guaranteeing redundancy so that, if a control plane fails, another can attend.</p><p class="px18">With the Kubeadm Control Plane provider (KCP), the operator can declaratively expand the Kubernetes control plane, thus managing availability and ensuring that the control nodes are organized, minimizing failures during the cluster lifecycle.</p><p class="px18">For worker nodes, just specify the number of nodes; the clusterAPI will provision the new CloudStack Instances and add them to the cluster. When using the Cluster Autoscaler, the number of worker nodes is automatically adjusted to the number of pods needed, thus meeting the access demand. Metrics can refer to application workload or average CPU usage for cluster tuning.</p></div></div></div></div></div></div></div></div></section></main><section class="m80px"><div class="container"><div class="row"><div class="col"><div class="section-title text-center mb-5">Learn More about Apache CloudStack</div></div></div><div class="row"><div class="col-lg-6 mb-4"><div class="apache-card bgd-blue"><div class="img-holder"><img src="/img/Apache%20CloudStack%20at%20a%20Glance_img.png" alt="" width="100%"></div><div class="apache-card-body"><div class="apache-card-title">Apache CloudStack at a Glance</div><p>Learn more about Apache CloudStack and the capabilities it provides for IaaS builders</p><a href="/files/cloudstack-at-a-glance.pdf" class="btn btn-primary btn-dark-blue">Download</a></div></div></div><div class="col-lg-6 mb-4"><div class="apache-card bgd-dark-blue"><div class="img-holder"><img src="/img/ATT-Gitops.jpg" alt=""></div><div class="apache-card-body"><p><br>During the annual CloudStack Collaboration Conference 2023, Alex Dometrius, Associate Director - Technology at AT&T, presented their journey with Apache CloudStack.</p><a href="/blog/cloudstack-and-gitops-at-scale" class="btn btn-primary">Read more</a></div></div></div></div><div class="row"><div class="col-lg-3 mb-4"><div class="apache-card card-border"><div class="img-holder"><img src="/img/Delivering%20Public%20Cloud%20Services_img.png" alt="" width="100%"></div><div class="apache-card-body"><p class="blue-title">SOLUTION BRIEF</p><div class="apache-card-title">Delivering Public Cloud Services with CloudStack</div><p>Discover how to use CloudStack to provision public cloud services and improve your profitability</p><a href="/files/acs-public-cloud-solution-brief.pdf" class="btn btn-primary">Download</a></div></div></div><div class="col-lg-3 mb-4"><div class="apache-card card-border"><div class="img-holder"><img src="/img/IKOULA_img.png" alt="" width="100%"></div><div class="apache-card-body"><p class="blue-title">CASE STUDY</p><div class="apache-card-title">IKOULA - The cloud leader & innovator in France</div><p>IKOULA Simplifies the Management of Large-Scale Cloud Infrastructure with CloudStack and XCP-ng</p><a href="/files/acs-case-study-ikoula-2021.pdf" class="btn btn-primary">Download</a></div></div></div><div class="col-lg-6 mb-4"><div class="apache-card card-border"><div class="img-holder"><img src="/img/Your.Online_img.png" alt="" width="100%"></div><div class="apache-card-body pt-0"><p class="blue-title">CASE STUDY</p><div class="apache-card-title">Your.Online – A leading European online services platform</div><p>Future-Proof Open-Source Platform Hosting Millions of Websites for Your.Online Powered by CloudStack, KVM and Ceph</p><a href="/files/acs-case-study-your-online.pdf" class="btn btn-primary">Download</a></div></div></div></div></div></section></div><footer class="footer footer--dark"><div class="container container-fluid"><div class="footer__bottom text--center"><div class="margin-bottom--sm"><a href="https://cloudstack.apache.org/" rel="noopener noreferrer" class="footerLogoLink_BH7S"><img src="/img/ACS_logo_slogan.svg" alt="Apache CloudStack logo" class="themedImage_ToTc themedImage--light_HNdA footer__logo"><img src="/img/ACS_logo_slogan.svg" alt="Apache CloudStack logo" class="themedImage_ToTc themedImage--dark_i4oU footer__logo"></a></div><div class="footer__copyright"> |
