Kubernetes coordinates containerised applications across a cluster. Declarative resources describe the desired workload, with scheduling, service networking and recovery controls. Teams can operate the upstream software or use a managed distribution. The platform is a foundation for application operations rather than a complete build, database and monitoring service bundled into one product. Learn more about Kubernetes
Who should take a closer look?Platform teams standardising container operations across services and environments
Capabilities to explore
- ✓Declarative workload scheduling
- ✓Service discovery and load balancing
- ✓Rolling deployment controls
Free self-managed platformUpstream Kubernetes is Apache-2.0 software without a software subscription fee. Managed services, compute and commercial support are separate.
Swarm mode is the clustering capability built into Docker Engine. It manages services and replicas across manager and worker nodes using Docker commands, with overlay networking and rolling updates. This profile covers current Engine Swarm mode, rather than the discontinued Classic Swarm project. It suits a team evaluating a direct Docker service deployment model.

Included in Docker EngineSwarm mode is included in Docker Engine. Engine is Apache-2.0 software; Docker Desktop has separate subscription eligibility rules.
Terraform defines and manages infrastructure through provider APIs. Teams version configuration, review a proposed change plan and apply changes while tracking resource state. Terraform CLI, HCP Terraform and Terraform Enterprise have different operational and commercial boundaries. Current CLI releases use a source-available Business Source License; they should not be described as unrestricted open-source software. Learn more about HashiCorp Terraform

Jenkins is a self-managed automation server for software builds, tests and delivery pipelines. Teams express pipeline stages in versioned Jenkinsfiles and extend the server through plugins and build agents. It offers substantial control over the execution environment, while leaving server security, plugin compatibility, capacity and backup operations with the organisation running it. Learn more about Jenkins
Who should take a closer look?Engineering teams with custom delivery pipelines and the ability to operate their own automation service
Capabilities to explore
- ✓Pipeline definitions in Jenkinsfiles
- ✓Plugin integrations
- ✓Distributed build agents
Free self-managed serverJenkins is available under the MIT License. Hosting, build machines and commercial support are not included.
CircleCI runs continuous integration and delivery pipelines configured in YAML. Its cloud service offers managed execution environments alongside self-hosted runner options, while CircleCI Server is a distinct private deployment offering. Resource class, execution time, storage and network consumption matter when estimating costs; a headline build-minute allowance does not represent every machine type. Learn more about CircleCI
Who should take a closer look?Development teams seeking managed CI execution with configurable resource choices
Capabilities to explore
- ✓YAML pipeline configuration
- ✓Managed execution environments
- ✓Workflows and parallel jobs
Free cloud tierCircleCI Cloud has a recurring Free plan with limited monthly credits and active users. Trials and open-source allowances have separate conditions.
Vercel is a managed platform for deploying web applications, with Git-linked previews and production releases. It combines application delivery, compute and project tooling, including integrations for modern web frameworks. A purchase should distinguish the personal Hobby plan from commercial team use and account for runtime and delivery consumption beyond the plan’s included resources. Learn more about Vercel
Who should take a closer look?Web teams evaluating a managed release platform for framework-based applications
Capabilities to explore
- ✓Git-connected deployments
- ✓Preview and production environments
- ✓Global application delivery
