Cloud Tools Pillar
Containers, Kubernetes orchestration, and infrastructure as code (Terraform, Pulumi) for shipping and running cloud workloads.
Containers
Package an app and its dependencies into a portable image
Orchestration
Run and scale containers across a cluster of machines
Infrastructure as Code
Define cloud resources in version-controlled config
Pipelines
Automate build, test, and deploy steps end to end
Provider-agnostic foundations
Tooling that runs across major clouds and on-prem

This pillar is the home for containers, orchestration, and infrastructure as code: the tooling teams use to build, ship, and run workloads consistently across cloud environments. New breakdowns, guides, and comparisons will land here as they are published.
Containers package an application together with its libraries and runtime so it behaves the same way on a laptop, a build server, and in the cloud. They are the unit of work that orchestration and pipelines are built around.
Orchestration platforms such as Kubernetes schedule containers across a cluster, restart them when they fail, scale them with demand, and route traffic between them, so applications stay available without manual intervention.
Infrastructure as code tools such as Terraform and Pulumi let teams define cloud resources in version-controlled configuration, then create and update them repeatably, replacing manual console clicks with reviewable, auditable changes.

Infrastructure as code compared: HCL vs real programming languages, state, providers and pricing.
Start with cloud foundations and provider coverage across the Cloud Tools Hub.
Container images, orchestration manifests, and infrastructure-as-code files often capture how and where your data is stored and who can reach it. Misconfigured access, exposed secrets in config, or an over-permissive cluster can create real risk. Review each tool's security guidance, keep secrets out of source control, and apply least-privilege access before running workloads with proprietary or regulated data.
DevOps and IaC tools evolve quickly, and provider behavior, licensing, and resource costs change over time. Infrastructure-as-code that provisions cloud resources can incur charges as soon as it runs. Before you apply changes against a real account, confirm the current tool documentation, licensing terms, and the cloud provider's live pricing, because the official sources are the only authoritative ones.
This hub is editorially independent, with no affiliate relationship with any tool maker or cloud provider named here. Tool descriptions are grounded in vendor documentation, and details that change over time should be confirmed against the source. You have data rights under GDPR (EU/UK) and CCPA (California); how those rights apply depends on the provider, the service, and your contract.
