1 Considerations for Adopting PaaS (Platform as a Service) Michael Dolan ([email protected]) Senior Field Engineer April

2 Becoming The Agile Enterprise To effectively achieve its missions, the Department of Defense must develop and update its software-based capabilities faster than ever, to anticipate new threats and respond to continuously changing requirements. David M. Wennergren, Former US DoD CIO cloud computing holds tremendous potential to deliver public value by increasing operational efficiency and responding faster to constituent needs. US Federal Cloud Computing Strategy The government needs agile cyber projects that are smaller in effort, have a potential for large payoff, and result in a rapid turnaround, creating a greater cost to the adversary to counter. DARPA Cyber Fast Track Program 2

12 The Agile Enterprise Needs PaaS IaaS without PaaS capabilities becomes a dying breed. The single most powerful thing you can do this year is to enable your developers with a fast and flexible PaaS. 12

13 From Today s Enterprise Delivery Processes 13

14 To Becoming an Agile Enterprise Dramatically improve developer experience Development Agile teams, rapid iteration Iteration Delivery Ingest and incubate open source innovation Continuous delivery, no planned downtime Operation Instant scaling of apps and data services Automation and deployment consistency Standardized service binding and discovery 14

15 PaaS is the operating system for the cloud. As the set of APIs and services for PaaS's grow, the choice of PaaS becomes more crucial as the costs of porting go up. Jonathan Rosenberg CTO & VP, Collaboration 15

16 DEFINE: Microservice If every service has to be updated in concert, it s not loosely coupled! Loosely coupled service oriented architecture with bounded contexts If you have to know about surrounding services you don t have a bounded context. 16

18 Not Traditional (ESB-centric) SOA UI Service Service Service Service UI Enterprise Service Bus Service Service Service Service 18
