The DevOps landscape continues to evolve. In 2025, we see the maturation of practices that were experimental just a few years ago. Platform Engineering and SRE (Site Reliability Engineering) are consolidating as the disciplines that define how companies deliver software.

Platform Engineering: The New Standard

What Is Platform Engineering?

It’s the discipline of designing and building internal platforms that allow developers to deliver software autonomously.

Instead of each team configuring its own infrastructure, a platform team provides:

  • Standardized CI/CD pipelines
  • Consistent development environments
  • Pre-configured observability tools
  • “Baked-in” security

Internal Developer Platforms (IDPs)

IDPs are the product that platform teams create:

┌──────────────────────────────────────────┐
│           Developers                      │
│  (Focus on business code)                 │
└────────────────┬─────────────────────────┘
                 │ Self-service

SRE: Reliability as a Discipline

SRE Practices in 2025

Companies are actively adopting:

SLOs (Service Level Objectives) Measurable reliability objectives:

  • Availability: 99.9%
  • p99 Latency: < 200ms
  • Error rate: < 0.1%

Error Budgets If you’re within SLO, you can take more risks (new features). If you’re outside, focus on stability.

Observability The three pillars:

  • Metrics: What’s happening
  • Logs: Why it’s happening
  • Traces: Where it’s happening

Incident Reviews Blameless post-mortems to learn from incidents.

CI/CD: State of the Art

Complete Automation

Modern pipelines include:

  1. Build: Compilation and packaging
  2. Test: Unit, integration, E2E
  3. Security: SAST, DAST, dependency scanning
  4. Deploy: Automatic to staging, manual to production
  5. Verify: Smoke tests, canary analysis

Deployment Strategies

Blue/Green Two identical environments. Instant switch between versions.

Canary New version to 5% of traffic, gradually increasing.

Feature Flags New functionality activatable without deployment.

GitOps: Infrastructure as Code

Everything lives in Git:

  • Application code
  • Infrastructure configuration
  • Security policies
  • Pipeline definitions

Changes via Pull Requests = automatic auditing.

Dominant Tools in 2025

How to Get Started

If You’re Starting Out

  1. Standardize CI/CD for all projects
  2. Implement basic observability (centralized logs)
  3. Define SLOs for critical services

If You Already Have Foundations

  1. Invest in Platform Engineering
  2. Formally adopt SRE practices
  3. Implement GitOps for infrastructure

If You’re Advanced

  1. Optimize Internal Developer Platform
  2. Automate incident response
  3. Implement FinOps for cost optimization

Measurable Benefits

Companies that adopt these practices report:

  • 50% less incident recovery time
  • 4x more deployments per month
  • 30% less operational costs
  • Better retention of developers

The Future: AIOps

The next frontier is AIOps: using AI to:

  • Predict incidents before they occur
  • Automate response to known problems
  • Optimize resources automatically
  • Correlate events across systems
