Deployment Modes

WireMock can be deployed in three distinct modes, each suited to different organizational needs and constraints:
  1. Cloud - Fully managed hosting
  2. Self-hosted - Complete on-premises deployment
  3. Hybrid - Control plane in the cloud, data plane on-premises

​
Cloud Deployment

With Cloud deployment, WireMock hosts everything for you:
  • Control plane - The management interface and API
  • Data plane - The mock API endpoints that respond to requests
  • User interface - The web-based UI for managing your simulations
All components are accessible from the internet with nothing to install or maintain. This mode provides:
  • Immediate availability with no infrastructure setup
  • Automatic updates and maintenance
  • Built-in scalability and high availability
  • Public accessibility for remote teams and external integrations
Cloud deployment is ideal for:
  • Quick prototyping and experimentation
  • Teams without dedicated infrastructure
  • Scenarios where public internet accessibility is acceptable
  • Organizations wanting zero operational overhead

​
Self-Hosted Deployment

Self-hosted deployment involves running the entire WireMock product stack on your own Kubernetes cluster. This mode requires you to:
  • Provide and manage a Kubernetes cluster
  • Provide and manage a Postgres database
  • Handle installation, updates, and maintenance
  • Configure networking, DNS, certificates and security
  • Monitor and scale infrastructure as needed
Self-hosted deployment offers:
  • Complete control over data and infrastructure
  • Ability to keep all traffic within private networks
  • Customization of deployment topology
  • Compliance with strict data residency requirements
This mode is appropriate for:
  • Organizations with security policies prohibiting cloud services
  • Scenarios requiring air-gapped or isolated network environments
  • Teams with existing Kubernetes expertise and infrastructure
  • Situations demanding complete data sovereignty

​
Hybrid Deployment

Hybrid deployment balances convenience with control by splitting the architecture: the control plane an UI remain in the cloud while API simulations are hosted in your infrastructure using WireMock Runner. Benefits of hybrid deployment:
  • Simplified management through the cloud-hosted UI
  • Data plane traffic stays within your network
  • Flexibility to deploy mock APIs where they’re needed
  • Reduced operational burden compared to full self-hosting
Hybrid deployment suits:
  • Development and testing workflows requiring local or private simulated APIs
  • CI/CD pipelines that can’t access public internet services
  • Organizations comfortable with cloud management but requiring private data planes
  • Scenarios needing simulated APIs in multiple diverse locations
