User Requirements Glen Wants “I want to return to my community and help encourage STEM learning in early stages (middle and high school)” “I want to help my teams build well-architected solutions using new and emerging technologies” “I want a 28-hour day...” Confidential 3

Microservices, why should I care? Understanding Cost (Operational and Cultural) ● Operational Cost (CI/CD Pipeline, Login, Monitoring, Tracing) ○ Cultural Cost (Collaboration, Waterfall Mentality, Coordination, Colocation) ○ Capabilities and Bounded Context ● How to identify and why do I need them? Which context I should care? Business or ○ technology Understanding the Spectrum of Enterprise Applications ● Existing Applications ○ Web Tomcat ■ Fast Monoliths ■ Java EE MSA ■ Li & Shi New Applications ○ Spring MSA ■ Reactive Connect & Extend ■ Serverless ■ Reactive JS ■ Rip & Re-Write API or Microservice: What’s the difference?
