Ed Burns discusses his career journey in software development and how the cloud has disrupted the industry. He began working on early web browsers and frameworks and witnessed "wars" between competing technologies. The rise of cloud computing inserted major vendors into the ecosystem and changed how software is developed and deployed. Azure aims to support all types of Java workloads throughout the development lifecycle and provides fully managed services for Spring Boot applications.

4. Brief Personal Journey
❑ You must constantly adapt
❑ Not necessarily frequently change jobs
❑ Companies need to adapt too

5. Starting on the Client: Birth of a Big Thing
Oil and Chemistry Building at University of
Illinois in Urbana-Champaign

Cobbles existing things together in an
exciting new way.
Simplicity: HTTP/1.0, TCP/IP sockets
Anyone can add new servers, no need
to ask permission.
Leverages network effect
Dabbling on the Server

8. Birth of the Monolith: Spring and J2EE
Addressed shared pain points
Transparent development process
Spring rode the crest of vendor
marketing efforts, differentiated
with operational excellence
J2EE had multi-vendor concept,
strong community governance

• Your very heart and soul.
• But seriously, yes.
• If you're passionate about software, you put at least some part of
your heart and soul into it. So the belligerents are fighting over
access to that part.
• Some would call this "mindshare" but I think that's too cold a term.
