Buzzword Positioning using the Gartner Hype Cycle

Codeless

  • Focus on functionality not code
  • Been around for years
  • RAD -Rapid Application Development
  • Re-invigorated by the Citizen Developer
  • Codeless or Low Code
Serverless
  • Focus on code not server
  • Solutions built with an abstraction from server
  • Characteristics
    • No VM to provision/manage
    • Dynamic vs Block Scaling
    • Cost dedicated compute vs per execution

Examples are:
Platform as a service
Backend as a Service
Function as a Service

Examples of Codeless & server less technology

  • Azure Scheduler
  • Azure Search
  • Cognitive Services
Considerations
Serverless
  • Lots of Serverless services on Azure
  • Empower teams
  • Free your IT Pro from low value tasks
  • Pay per execution or pay for reserved capacity (Warning about possible costs)
Codeless (Power apps & flow)
  • Work within constraints mean you can write less code
  • Serverless can work with codeless or lots of code solution
What should I choose?
  • Have company preferences/principles
  • Try to be consistent
  • Align choices to team skills sets
  • Align choices to IT strategy
Q&A about On prem vs Cloud costs.
Cloud enables actual charge back for applications, moving IT is expensive to HR costs X.
Now systems are created with “How can I show billing data for this application back to the business”

Is there a standard coming to enable comparing services & functions between clouds? "Yes, website URL promisied"
