Web APIs, the New Language Frontier

  1. 1. WEB APIS, THE NEW LANGUAGE FRONTIER All-in-one web API platform http://apispark.com Jérôme LOUVEL jlouvel@restlet.com CEO December 4, 2013
  2. 2. Part 1 EVOLUTION OF PROGRAMMING LANGUAGES
  3. 3. TOP PROGRAMMING LANGUAGES C is still the first language ! Assembly is still in the top 20 ! Source: TIOBE Index
  4. 4. A TALE OF ABSTRACTION HOP, APISpark, WebShell Web API languages Java, JS, Dart, Groovy Application languages C, C++, C#, Obj-C, Go System languages NASM, TASM Intel, AMD, SPARC Assembly languages Hardware Web scale, high availability, multi-tenancy Productivity, portability, business logic Native/OS code, very high performance Lowest level language, tedious maintenance
  5. 5. WEB API LANGUAGES CURRENT STATE • Can describe Web APIs – XML or JSON driven representations – proper HTTP methods usage – markup languages (XML, JSON, YAML, MarkDown) • Can generate code – client SDKs – server skeleton
  6. 6. WEB API LANGUAGES NEXT STAGE ? • Let developers program the Web – through web APIs instead [Java/JS] APIs – natively speaking the HTTP semantics – not only the API contract, also the implementation ! • Web APIs can be local or remote – inherently component-based – ready for load-balancing, scaling, cross-region • Cloud-ready implementations – multi-tenant execution – run on-top of IaaS – built-in persistence service (synchronized APIs life cycle) … JavaScript based Internal DSL HOP pioneer
  7. 7. Part 2 RETHINKING WEB API DEVELOPMENT
  8. 8. API EDITOR • Let developers code at the API level – Visual editor – Command line editor • Cloud ready – collaborative edition • think Google Docs and GitHub style – easy composition of multiple APIs • via import instructions • easy discovery mechanism (like Linux or Java package managers)
  9. 9. API COMPILER Web API languages Generates [Java] code Application languages Generates [JVM byte code] System languages Generates assembly code Assembly languages Generates CPU operations Hardware Compilers translate higher-level languages into lower-level languages
  10. 10. API DEBUGGER • Let developers debug API calls – HTTP centric, semantics and transport data – pause, stop, continue, set breakpoints – works like a [Java] debugger • Works on both server and client sides – support both synchronous and asynchronous calls – lot of room for innovation! … Interactive HTTP proxy
  11. 11. API RUNNING • Let developers run APIs – similar to using web API frameworks on top of application languages (eg. Restlet Framework for Java) – similar to API deployment (developer environment) • Special features – no separation between framework and actual language for better productivity – lot of room for innovation! … Restlet Framework based Node JS based
  12. 12. API DOCUMENTATION • Let developers document APIs – technical documentation easy to maintain – tools similar to Javadocs to keep documentation close to the code – still needs separate user guide and tutorials • Currently mature on the API contracts – what about the implementation details?
  13. 13. API DEPLOYMENT • Let developers deploy APIs – like Eclipse IDE deployment of Web packages (WAR) to remote application servers – as simple as pressing a button – targets either staging or production environments • Special features – built on top of IaaS – cross-region deployment as a key option • for high-availability • for low latency (geo-DNS routing)
  14. 14. Part 3 AN ILLUSTRATION WITH APISPARK
  15. 15. STEP 1: CREATE ENTITY STORE
  16. 16. STEP 2: EXPORT WEB API
  17. 17. STEP 3: DEPLOY WEB API
  18. 18. STEP 4: MONITOR YOUR WEB API
  19. 19. Part 4 CONCLUSION
  20. 20. PAAS 2.0 • IaaS is a revolution – fully embraced web APIs – provides a disruptive new abstraction layer • PaaS 1.0 is just an evolution – – – – only simplifies the deployment aspects same application languages, similar complexity/time/cost slow adoption compared to IaaS stellar growth adapts existing development practices to the Web • Time for PaaS 2.0 ! – fully embrace web APIs as a disruption factor – cross-region deployment, zero-downtime, low latency will become standard in SLAs  your web API can’t stop your partners – development costs and time to market can be reduced A whole new web API game is starting !
  21. 21. BREAKING NEWS ! • Seed round recently announced – $2M raised • to expand our Engineering team in France • to accelerate our Marketing efforts in the US – Experimented board including • Bertrand Diard, co-founder of Talend, Los Altos • Matthieu Hug, CEO Fujitsu RunMyProcess, Paris • Reza Malekzadeth, VP Business of Cumulus, Los Altos – Third co-founder • Stève Sfartz, VP Engineering (see talk tomorrow) • APISpark Public Beta ! – starting today at APIdays Paris – no more waiting list – looking forward to getting your feed-back! http://apispark.com
