Red Hat Immersion 2023 Service Offerings and Labs - Features and Services

About Red Hat and Openshift

• Red Hat known for Linux, Openshift, open source contributions, developer tools - many built in Ontario
• Openshift
  • For service designers, full stack developers, DevOps
  • Used by many organizations and Canadian regions

British Columbia Developers’ Exchange - Todd W.

• BC Developers’ Exchange goal was to increase digital delivery in public service
• Issue: public service projects found that development took many months and delivery years leading to outdated solutions

Why using technologies is important?

• Agile - small chunks

• Consistent improvement, delivery of services

• Dr. Eliyahu Goldratt, developer of the Theory of Constraints, speaks to this issue directly: “Technology can bring benefit if, and only if, it diminishes a limitation.”

• Reality of IT is complex, fragmented, and many connections - people, process, and technology

How to Improve Digital Delivery?

Use a platform to address infrastructure, application, people & process areas:

• Infrastructure
  • Simplify
    • Automated
      • Example firewall operator accessible to developers for self service
    • Complexity abstracted
    • Secure by default
• Application
  • Standardize
    • Lower cognitive load, developers don’t need to know everything
    • Opinionated frameworks
    • Reuse
• People & Process
  • Accelerate
    • X as a Service
    • Feedback from all teams, not just platform
    • DevSecOps

Found people need quick start guides and physical solutions, not just principles.

Vision, Mission, Physical Platforms

• Vision was focusing on success of app delivery teams, digital transformation will follow
  • Quicker hiring, procurement
  • Treat developers like customers
  • Make platform like a product

Building Platform

• Need people with DevOps skills, pathfinder team when creating platform:
  • Sponsor
  • Product owner
  • Architect
  • Developer
  • Operation admin
  • UX/CX designer
  • Policy/process analyst
  • Communications expert
• Start small, communicate and sell to others

Platform operating model

• Self service

• Environment Standardization

• Auto scaling

• Community sharing, standards, common approaches

• Automation: testing, software

• Infrastructure as Code

• Platform engineer, app developer have different and integrated roles and tools

• Performance measures of platform:

  • App delivery time, rate, total app hosting
    • Cost/time reduction compared to traditional deployment
  • Stable and secure architecture
    • Reduced vulnerabilities fix time
  • Automate hybrid
    • Short change window
  • Digital transformation
    • App delivery

Platforms

• Openshift
  • On Premise
  • Azure clusters
• Tools: Rocket.chat, keycloak, GitHub, Selenium, Jenkins, sonarqube
