5 Time to live Typical focus of our community Live! Slide 5

6 Lean software development Mike Ogorek, Slide 6

7 Lean software development Burn the fat, feed the muscle... Slide 7

8 Lean software development principles Eliminate waste Create knowledge Build quality in Defer commitment Deliver fast Respect people Improve the system Slide 8

9 Time to live biggest remaining opportunity to reduce fat Live! Slide 9

10 Time to live Prepare staging env. Prepare production env. Live! Slide 10

11 Time to live Developer Test team Ops team Live! Slide 11

12 Eliminate waste 3 biggest sources of waste Extra features Develop just those 20% of the features that give 80% of the value Crossing boundaries Organizational boundaries typically increase cost by over 25% Churn Avoid specifying too early, testing too late Slide 12

13 The simple case... How lean can the simple case be? Slide 13

14 Status check... Slide 14

15 Platform-as-a-Service Google's App Engine we provide the web container, you provide the app supports Java and Groovy Platform services Datastore memcache URLFetch with Secure Data Connector Mail Google accounts based authentication Simple cron-based scheduling Slide 15

16 Demo Using STS and Groovy to build and deploy an application to GAE

17 Google App Engine Slide 17

18 Demo Using Grails to build and deploy an application to GAE

19 Data Center as a Service Amazon EC2 you provide the machine images, we provide the data center more to do than PaaS model but more control can exploit pre-built machine images Data center services S3, EBS, SQS, DevPay, CloudFront, SimpleDB,... Slide 19

20 Demo Using STS to launch a cluster of dm Server instances in EC2 and deploy an app.

21 STS and EC2 Slide 21

22 STS and EC2 Slide 22

23 I want to use my own data centre! Use-your-own-data-center-as-a-service Forrester: Ultra-modular computing Bring the same benefits of lean deployment to applications that run on-premise VMware Slide 23

24 VMware vsphere and vcloud Slide 24

25 VMware Lab Manager Slide 25

26 Demo Virtual QA Environment with tc Server, AMS, and Lab Manager

27 VMware Lab Manager Slide 27

29 Lean software development principles Eliminate waste Create knowledge Build quality in Defer commitment Deliver fast Respect people Improve the system Slide 29

30 Create knowledge Planning is useful, learning is essential Standards exist to be challenged and improved Embody the current best-known practice in standards, encourage challenging of them Predictable performance is driven by feedback Do not guess about the future and call it a plan. Develop the capacity to react as the future unfolds Use the scientific method Slide 30

31 Deployment blueprints Firing up a single image, or set of identical images is useful in the simple case SpringSource value: simple and powerful... Most production use cases require a set of co-operating machines, playing differing roles Slide 31

32 Spring recap! Application blueprint Application context ClassPath... FileSystem... Web... Dependency injection Configuration Abstraction from environment... Slide 32

34 Deployment context An application context instantiates an application blueprint and manages components A deployment context instantiates a deployment blueprint and manages instances EC2DeploymentContext User data, AMIs VMwareDeploymentContext Environment document, OVF Slide 34

35 Long-needle Injection user data / environment document xmi dm Svr A Slide 35

36 Demo Using Cloud Foundry to create a cluster specification and deploy a Spring app

44 Lean software development principles Eliminate waste Create knowledge Build quality in Defer commitment Deliver fast Respect people Improve the system Slide 44

45 Lean software principles Defer commitment Abolish the idea that it is a good idea to start development with a complete specification Break dependencies Maintain options Schedule irreversible decisions at the last responsible moment Deliver fast Rapid Delivery, High Quality, and Low Cost are Fully Compatible Companies that compete on the basis of speed have a big cost advantage, deliver superior quality, and are more attuned to their customers' needs. Slide 45

46 Lean software principles Improve the system Brilliant products emerge from a unique combination of opportunity and technology. Focus on the Entire Value Stream from concept to cash from customer request to deployed software Deliver a Complete Product Develop a complete product, not just software. Complete products are built by complete teams. Measure UP Slide 46

47 Summary Time-to-live Lean principles applied all throughout build, run, manage cycle Models Platform-as-a-service Data-Center-as-a-service Your-own-data-centre-as-a-service Hybrids Spring and SpringSource technologies support all of these models today! Lots more innovation coming down the pipeline... Slide 47
