The industry standard certification for validating skills in installing, configuring, and managing production-grade Kubernetes clusters. It focuses heavily on practical, hands-on problem-solving scenarios that real-world sysadmins encounter daily.
Designed for software engineers and developers, this cert proves proficiency in designing, building, configuring, and exposing cloud-native applications for Kubernetes. It is essential for those bridging the gap between dev and ops teams.
An advanced-level certification that tests the ability to secure containerized applications, Kubernetes platforms, and their supply chain. It is highly recommended for senior administrators focusing on cluster hardening and vulnerability management.
Focuses on installing, configuring, and troubleshooting core Kubernetes ecosystem components like the network, storage, and service mesh. It is ideal for administrators who need deep knowledge of the underlying infrastructure supporting K8s.
Formerly the gold standard for container basics, this certification validates expertise in Docker ecosystem components including Dockerfiles, container networking, and swarm orchestration. It serves as a great foundational step before tackling K8s.
A performance-based exam that validates the ability to manage containerized applications on Red Hat Enterprise Linux. It emphasizes practical skills in integrating containers into enterprise environments using Red Hat OpenShift and CLI tools.
While not exclusively Kubernetes-focused, this certification covers Azure Kubernetes Service (AKS) extensively. It is crucial for sysadmins managing hybrid cloud environments where Kubernetes runs on Microsoft Azure infrastructure.
An entry-level certification designed to provide a solid foundation in cloud-native concepts and basic Kubernetes operations. It is perfect for beginners entering the field who need to understand the broader CNCF ecosystem.
Validates skills in deploying and managing cloud-native applications using VMware Tanzu and Kubernetes. It is particularly relevant for enterprises heavily invested in VMware infrastructure transitioning to containerized workloads.
Offered directly by The Linux Foundation, this program often bundles CKA training and exam vouchers. It ensures candidates receive high-quality, standardized preparation from the organization that created Kubernetes.
Covers advanced deployment, automation, and monitoring practices, including extensive use of AWS EKS. It is ideal for sysadmins who need to integrate Kubernetes deeply within the Amazon Web Services ecosystem.
Includes significant coverage of Google Kubernetes Engine (GKE), covering design, implementation, and management. It is essential for architects and admins optimizing workloads on Google's managed Kubernetes service.
Validates expertise in managing Red Hat OpenShift on IBM Cloud. It is specifically tailored for administrators working in enterprise environments that leverage IBM's hybrid cloud and open-source technologies.
Though deprecated for new exams, understanding Docker Swarm concepts remains useful for legacy systems. This historical knowledge helps admins troubleshoot older containerized setups still in operation within some organizations.
Validates skills in administering Red Hat OpenShift Container Platform, an enterprise Kubernetes distribution. It is critical for sysadmins in large enterprises using OpenShift for secure, multi-tenant container management.
Provides a fundamental understanding of cloud-native applications and Kubernetes architecture. It is a great starting point for IT professionals transitioning from traditional infrastructure to cloud-native paradigms.
While the original product has evolved, historical certifications in enterprise Kubernetes distributions like Tectonic (now part of Red Hat) highlight the importance of managing secure, compliant clusters in regulated industries.
Focuses on managing containerized workloads on SUSE Linux Enterprise. It is relevant for sysadmins in European markets or industries heavily using SUSE infrastructure for their container deployments.
Covers Ubuntu-based cloud infrastructure, including MAAS and Juju, which often interact with Kubernetes. It is useful for admins using Ubuntu as their base OS for container hosts and orchestration nodes.
Although an IaC certification, it is vital for managing Kubernetes infrastructure declaratively. Sysadmins use it to automate the provisioning and scaling of K8s clusters across multiple cloud providers.
