The work itself
What you would spend time doing
Build capabilities other teams can use reliably: delivery pipelines, environments and service tooling. Platform engineering and SRE differ by employer, so inspect the actual remit.
Platform engineering
Platform / DevOps Engineer → SRE
An engineering role building capabilities that other teams can reliably adopt.
Explore the work, check your starting point and try one scoped task before committing to a course or exam.

- Target roleSRE
A general route, not a personal plan. Linked guides describe the broader role family; a junior or support starting point may have a narrower remit. Compare the responsibilities with the actual vacancy.
Phased progression
Build on your existing experience, demonstrate the next responsibility and review it with the people who rely on your work.
Progress through demonstrated capability and agreed responsibility. These stages are not a fixed timetable or a salary ladder.
Build on existing experience
Your starting capability
Practical focusReview your existing work against Junior DevOps / SRE responsibilities. Identify one gap in judgement, delivery or ownership and agree a scoped way to demonstrate it.
Something to demonstrateA short account of what you can already do and the next gap to investigate.

Demonstrate readiness
Move into the specialism
Practical focusExplore Junior DevOps / SRE responsibilities. Check the supervision and prior experience expected; demonstrate the relevant work before increasing your scope.
Something to demonstrateA small repository, passing and failing test evidence, and a rollback note written for another developer.
In focus Junior DevOps / SRE
Demonstrate reliable practice
Specialisation
Practical focusTake on a scoped responsibility, test your decisions and collect feedback. Add a credential only where it supports that work.
Something to demonstrateA test record and feedback showing how you improved a piece of work.

Broaden responsibility
Deepen, lead or move sideways
Practical focusPrincipal SRE or Platform Lead. Own the contracts the platform makes with product teams.
Something to demonstrateExamples of broader ownership, with the scope and responsibility agreed.
Your starting point
What to bring to this route
Demonstrate software or systems fundamentals and safe automation. Ask whether the role builds a platform, operates services or mainly maintains deployment scripts.
Ask a course provider or employerWho are the platform users, how is success measured, and what operational load sits with this team?
The verdict
You enjoy building internal products other engineers will rely on. You can hold a roadmap, not just a backlog of YAML changes.
A platform can become an unused collection of tools. Ask how users influence priorities, how adoption is evaluated and who owns support and lifecycle changes.
Certification sequence
Study options, not a checklist. Choose for the work you need to demonstrate, then check the provider’s current requirements and renewal terms.
Primary
Explore these first
Compare the subject with the work you want to do. Check eligibility before committing.
- AWS Solutions Architect AssociateChoosing AWS compute, storage, networking and data services around resilience, security, performance and cost.
- Terraform AssociateTerraform configuration, providers, state, modules and the plan-and-apply workflow.
- CKARunning Kubernetes clusters: workloads, networking, storage, access and troubleshooting.
Supporting
For a particular platform or gap
Choose one when its syllabus addresses a gap you need to practise.
- CKADRunning applications on Kubernetes: workload definitions, configuration, services, observability and deployment.
- CKSSecuring Kubernetes from cluster configuration and workload deployment through to runtime monitoring.
- AZ-400Software delivery with Microsoft's DevOps tools, including source control, pipelines, security and feedback.
Long-term
As your responsibility grows
Revisit when your scope changes. Experience and renewal requirements still apply.
No specific credential suggested at this stage.
Practical projects
Produce something you can explain, test and improve with feedback.
A scoped starting exercise
Try the work before choosing the route
Use a tiny sample application to create a pipeline with one automated test. Make the test fail deliberately and document when delivery must stop and how to recover.

Free text worksheet · no account needed. Add your checks, results and feedback as you work.
Review the evidence
- Does a failed check stop the change rather than merely print a warning?
- Can another person use the instructions and understand the service limits and recovery steps?
Label planned, simulated and completed work accurately. A practice exercise helps you test your interest and reasoning; it does not establish production experience or guarantee an interview.

Realistic expectations
Check these assumptions against the course, vacancy or team you are considering.
Misconception
That a title or credential establishes readiness by itself. Compare your software and operating evidence with the platform users and services involved.
Readiness check
Compare your software and operating evidence with the platform users and services involved. Building a capability other teams can adopt is more informative than a fixed tenure in DevOps.
