1004 z2 env_positioned

  1. 1. 2 The z Environment - positioned - © ZFabrik Software KG 2010
  2. 2. Intro ● The z2 Environment lives on sources ● It removes the complexities of build & deploy ● It implements immediate integration ● We will compare this with A)The classical way of Java team development B)The Maven approach © ZFabrik Software KG 2010
  3. 3. What's the Problem? Have a consistently up-to-date execution environment for development and production Efficiently develop and support your solution © ZFabrik Software KG 2010
  4. 4. In Principle... Dev, QA, or Prod. Runtime Sources Define what's happening there , bug M de od t, t es por ify T p su Developers © ZFabrik Software KG 2010
  5. 5. So, Where is the Problem? ● Java application servers do not live on sources but rather on binaries ● It is up to the development organization to (somehow) provide those binaries and hence... ● … find out what binaries are affected by a change ● … find out what binaries belong to one solution ● … keep development environments up-to-date ● … integrate changes (continuously) ● … live with delays between commit and run © ZFabrik Software KG 2010
  6. 6. The “classical” approach Sources Nightly build QA. Runtime (everything?) deploy/push (everything?) Deployables commit changes Check out and central Dev. Runtime local Dev build (what?) deploy/push (workspace) Developers (what?) Deployables debug © ZFabrik Software KG 2010
  7. 7. The “classical” approach Sources Nightly build QA. Runtime (everything?) deploy/push (everything?) Deployables How “hard” is it to How “equal” are these? commit changes Check out and introduce a structural change? How “hard” is it to get this central up to date? Dev. Runtime local Dev build (what?) deploy/push (workspace) Developers (what?) Deployables debug What are the sources of © ZFabrik Software KG 2010 what you are debugging (but others change)?
  8. 8. The “classical” approach ● Ok for monolithic projects (only few deployables) ● Breaks for modular systems (too complex to keep in sync: Due to the “push” approach, it's up to the developer to keep things straight) ● Breaks for large projects (turn around times too long) ● Summary: Simple but doesn't scale. © ZFabrik Software KG 2010
  9. 9. The Maven Way Sources QA. Runtime Continuous depoy Integration deploy/push ush SNAPSHOT Repo p loy/ de p commit changes Check out and central se Release Repo Dev. Runtime ea local rel (workspace) Developers h us /p oy Dev Build pl de (mvn) Deployables debug © ZFabrik Software KG 2010
  10. 10. Who maintains The Maven Way all this infrastructure? Sources QA. Runtime Continuous depoy Integration deploy/push ush SNAPSHOT Repo p loy/ How hard is it to How “equal” are these? de p keep the commit changes Check out and dependency version vector right? How “hard” is it to get this central se up to date? Release Repo Dev. Runtime ea local rel (workspace) Developers h us /p oy Dev Build pl de (mvn) Deployables binary release management requires extreme care debug What are the sources of © ZFabrik Software KG 2010 what you are debugging (but others change)?
  11. 11. The Maven Way ● Maven is built around versioning, versioned dependency and release processes for binaries ● It does not address the system consistency side of things ● It is geared towards a distributed, independent community of producers of libraries ● It does not care about source consistency ● Summary: Useful for the community, much less interesting for solution providers. © ZFabrik Software KG 2010
  12. 12. 2 And in z Sources Dev or QA Runtime QA. Runtime Pull what has changed since the last pull Pull sinc what h commit changes Check out and e th a e la s chan st p ull ged central Dev. Runtime Pull from workspace with prio (workspace) Developers Debug © ZFabrik Software KG 2010
  13. 13. 2 In z ● A runtime that updates itself on-demand, according to changes in source repositories ● Developer runtime takes developer workspace into account with preference ● The runtime is a faithful representation of the repository – no question where sources are. ● Almost like a scripting environment © ZFabrik Software KG 2010
  14. 14. Summary ● Standard Java development approaches do either not scale (classical approach) or do not have solution providers in mind ● The z2 Environment is most useful for team development of solutions, rather than for providing libraries to the community © ZFabrik Software KG 2010
