Azure DevOps Engineer is the role responsible for designing and implementing CI/CD, IaC, GitOps, and SRE practices using Azure DevOps Services and GitHub. It is one of the most in-demand positions among Japanese DevOps, SRE, and platform engineering job openings. Salaries land in the JPY 9-14M range for senior DevOps and JPY 15-20M for principal/platform engineering roles. This article walks through the standard path from zero to Azure DevOps Engineer (AZ-900 → AZ-104 → AZ-400 → specialization), combining certification milestones, hands-on experience, and adjacent domains such as Kubernetes and multi-cloud.
The standard path to Azure DevOps Engineer breaks down into the following three stages.
| Stage | Certification | Duration | Cumulative Hours | Position Reached |
|---|---|---|---|---|
| 1 | AZ-900 (Fundamentals) | 1 month | 25-40 hours | Azure concept fluency |
| 2 | AZ-104 (Administrator) | 3-4 months | +100-150 hours | Operations and implementation basics |
| 3 | AZ-400 (DevOps Engineer Expert) | 3-4 months | +100-150 hours | DevOps Engineer Expert |
| Total | 7-9 months / 225-340 hours | Entry to senior DevOps | ||
Either AZ-104 or AZ-204 (Developer) is a prerequisite for the AZ-400 Expert credential. Since AZ-204 retires on July 31, 2026, the AZ-104 → AZ-400 route is the safer choice for new candidates. Realistic timelines: 7-9 months with 1-3 years of IT experience, 5-7 months with prior development experience, and 10-12 months for complete beginners.
The AZ-400 prerequisite can be satisfied by either AZ-104 or AZ-204.
| Aspect | AZ-104 Route (Platform-leaning) | AZ-204 Route (Developer-leaning) |
|---|---|---|
| Orientation | Infra operations / IaC / cloud governance | App development / containers / microservices |
| Target Role | Platform Engineer / SRE | Application DevOps Engineer |
| Recommendation in 2026 | Recommended (accounts for AZ-204 retirement) | Only as a last-minute push before retirement |
AZ-400 touches on AKS (Azure Kubernetes Service) but does not go deep. Kubernetes is effectively a required skill in real-world DevOps and platform engineering roles, so pairing AZ-400 with a Kubernetes certification is strongly recommended.
The AZ-400 + CKA + CKS trifecta is a strong differentiator for senior DevOps/SRE roles in the JPY 12-18M salary range.
AZ-400 covers three IaC tools — Bicep, ARM, and Terraform — with weighting in the order Bicep > ARM > Terraform. The realistic balance for real-world skills is below.
After AZ-400, specialization is what carries you into a strong senior DevOps position.
Many Japanese enterprises run a mix of Azure, AWS, and GCP, and the market value of multi-cloud DevOps engineers is rising rapidly.
AZ-400 + AWS DevOps Pro + Terraform Associate is a combination frequently listed in senior platform engineer and SRE openings at global companies.
What is the standard path to becoming an Azure DevOps Engineer?
The standard path is AZ-900 → AZ-104 → AZ-400. AZ-104 (Administrator) gives you broad Azure operational knowledge, and AZ-400 (DevOps Engineer Expert) integrates CI/CD, IaC, and SRE practices on top of that. There is also an AZ-204 (Developer) route (AZ-900 → AZ-204 → AZ-400), but since AZ-204 retires in July 2026, the AZ-104 route is the safer choice for new candidates. Reaching the Expert credential via AZ-104 → AZ-400 typically takes 7-9 months of study, after which SC-300 (DevSecOps focus) or AZ-305 (architecture integration) are the standard next steps.
Can I pass AZ-400 if I only know GitHub?
No. AZ-400 covers Azure DevOps Services and GitHub in roughly equal measure. You also need to learn Azure Pipelines YAML syntax, Azure Boards/Repos workflows, and Azure Artifacts. Candidates coming from a GitHub Actions-only background typically need 30-50 hours to catch up on Azure DevOps Services UI and terminology (Project, Repository, Build, Release, Variable Group). In practice, many Japanese enterprises run a mix of Azure DevOps Services and GitHub, so engineers fluent in both command a higher market value.
Should I pursue Kubernetes certifications (CKA / CKAD / CKS)?
Strongly recommended. AZ-400 touches on AKS (Azure Kubernetes Service) but does not go deep. In real DevOps and platform engineering roles Kubernetes is effectively a required skill, and pairing AZ-400 with CKA (Kubernetes Administrator) or CKAD (Kubernetes Application Developer) is highly valued in the job market. The AZ-400 + CKA + CKS (Kubernetes Security) trifecta is a strong differentiator for senior DevOps/SRE roles in the JPY 12-18M salary band. Microsoft also keeps shipping Kubernetes-based services (Azure Container Apps, Azure Operator Nexus), so the long-term value of Kubernetes skills only keeps rising.
Which IaC tool should I learn — Bicep, Terraform, or ARM?
Bicep as your primary tool and Terraform as your secondary is the realistic balance. Bicep is the Azure-specific DSL Microsoft positions as the ARM successor, and it is the de facto choice for new IaC on Azure projects. Terraform is HashiCorp's multi-cloud tool, and organizations also running AWS/GCP often already have it entrenched. ARM templates use the older JSON format and are low priority unless you are maintaining legacy code. On AZ-400, the weighting goes Bicep > ARM > Terraform, so prioritize Bicep for exam prep. For real-world value, learn Terraform in parallel to position yourself as a multi-cloud DevOps engineer.
What is the salary range for DevOps engineers?
In Japan, salaries vary widely by role and experience. Junior DevOps (1-3 years): JPY 5-8M. Mid-level DevOps (3-6 years): JPY 7-11M. Senior DevOps/SRE (6-10 years): JPY 9-14M. Principal DevOps / Platform Engineer (10+ years): JPY 12-20M. A Kubernetes-integrated stack like AZ-400 + AZ-104 + CKA + CKS, or a multi-cloud stack like AZ-400 + AWS Certified DevOps Engineer Professional + GCP Professional Cloud DevOps Engineer, makes the upper end of these ranges much more reachable. Senior DevOps roles at global or foreign-capital firms can stretch to JPY 15-25M. As a freelancer, JPY 120K-200K per day is a realistic rate.
