About OpenFaaS Essential Training.
Understand where OpenFaaS fits in modern software delivery, what this level covers, and how the program builds practical confidence step by step.
Program overview
OpenFaaS is taught as a practical technical skill for modern engineering, operations and platform teams. The course explains where the tool fits, how it is used in real delivery environments, and how learners can apply it through guided practice.
This DevOpsSchool OpenFaaS program is built for working professionals who want usable skills instead of only conceptual exposure. The training emphasizes live examples, workflow clarity, operational controls and progressive skill depth from Foundation to Essential.
Private OpenFaaS training for delivery teams, platform groups and engineering organizations.
DevOpsSchool provides corporate OpenFaaS training for teams that need faster adoption, workflow standardization, administrative control, integration guidance and governance-ready rollout. Private batches can be aligned to development practice, release workflow, access model, maturity level and internal tooling.
- Private online or classroom delivery for engineering teams
- Aligned to OpenFaaS usage maturity, admin depth and collaboration patterns
- Useful for rollout, migration, governance and workflow consistency goals
- Can be tailored for developers, administrators, DevOps teams and leadership stakeholders
Why teams use DevOpsSchool
DevOpsSchool combines live demonstration, practical workflow discussion, implementation-oriented examples, and strong post-session learning support. That makes the training more usable for real teams than generic slide-led courses.

Why OpenFaaS matters
- OpenFaaS helps teams standardize a critical part of their software delivery, infrastructure, automation or operations workflow.
- It gives learners a repeatable way to move from basic usage to confident execution in team and enterprise environments.
- For DevOps and platform teams, OpenFaaS becomes more valuable when connected with automation, governance, monitoring and delivery practices.
- Teams using OpenFaaS effectively reduce ad-hoc execution and move toward consistent engineering standards.
Objectives
- Understand OpenFaaS concepts, architecture, terminology and operational usage patterns.
- Learn practical configuration, workflow design, access controls, team usage and quality practices.
- Apply OpenFaaS in real delivery workflows using automation, integrations, traceability and governance patterns.
- Build practical confidence to use OpenFaaS for individual, team and organizational use cases.
Pre-requisites
- Basic computer literacy and familiarity with software development workflows.
- Helpful but not mandatory: introductory DevOps, cloud, automation or software delivery awareness.
- No deep programming background is required for the Foundation and Essential levels.
Who this course is for
- Developers, administrators and engineers who need practical OpenFaaS usage skills.
- DevOps engineers, release engineers, SREs and platform teams managing delivery standards.
- Engineering leads and technical managers responsible for workflow quality, access controls and governance.
- Corporate teams migrating to or standardizing on OpenFaaS.
