Irrspctiv of th starting point, th sam APIs will b ffctiv for all scnarios A. Mobilizing mainfram assts Mobil app rquirs accss to backnd srvics Businss rquirs th ability to publish ths srvics to mobil app dvloprs Businss rquirs th ability to monitor and manag usag of backnd srvics by nw mobil applications B. Cloudifying nw applications Cloud app rquirs accss to backnd srvics Businss rquirs th ability to publish ths srvics to (intrnal and xtrnal) app dvloprs Businss rquirs th ability to monitor and manag usag of backnd srvics by nw cloud applications C. Improving consumability and accss control to xisting assts Businss rquirs controlling workload and gaining visibility for chargback and accountability Businss rquirs agility in modifying xisting assts without having to rgrssion tst th ntir st of applications Quick accss to data trappd in mainfram assts D. Participating in th API Economy Mobil app rquirs accss to backnd srvics Businss rquirs th ability to monitor and manag usag of backnd srvics by nw mobil applications

10 Businsss ar transforming thmslvs to participat in th API conomy How do you rapidly and scurly xpos your businss to this dvlopr cosystm? IBM API Managmnt Expos businss srvics scurly as APIs to dvlopr communitis, and analyz API usag Provid slf-srvic API portals to xtrnal/intrnal app dvloprs Manag & monitor th ntir API platform Off-prmis On-prmis SaaS privat Off-prmis privat Hybrid

11 Why API Managmnt? Businss challngs addrssd with APIM in xposing z basd srvics/assts Mobil Applications Cloud APIs Cloud-basd Srvics On-Prmis Entrpris APIs E n t r p ri s S r v i c s CICS IMS WAS TPF Mobil, Cloud and Third-party Applications invoking z Srvics using APIs 1. Consumability of th APIs is Ky: Easir cration and assmbly of API from xisting assts/srvics Visibility of APIs to intrnal and xtrnal dvloprs Easir rgistration (by consuming applications) and st up including managing ntitlmnt 2. Rtaining businss control (.g., nforcing ntitlmnt, accountability/chargback) and gaining businss insight in API invocation Scuring APIs using a scur GW from unwantd xtrnal invocations (mapping to application lvl scurity) and nforcing workload ntitlmnt Businss Monitoring of API accss in gaining businss insight on th us of APIs by xtrnal applications, and for accountability/chargback

12 Exposing Entrpris Srvics as APIs SOA fforts hav bn drivn by achiving dvloprs productivity gain and nabling rus of functions, i.., focusd on dvlopmnt of srvics. API Managmnt, on th othr hand, is drivn by consumption of ths srvics, i.., improving consumability of ths srvics for both xtrnal and intrnal dvloprs of applications accssing ths APIs, whil also rtaining control by th providrs of ths APIs Improving consumability includs listing APIs in a browsabl/sarchabl catalog, and making it asy to rgistr applications with th right ntitlmnt lvl Rtaining control includs not only nforcing ntitlmnts and managing workloads, but also providing insight basd on accss history and accountability for chargback.

13 Rols in Thr-tir Architctur for API Cration and Consumption 1. Bob: Dvlopmnt of Entrpris srvics from xisting z assts, making it asy to invok ths applications z application nvironmnts (CICS, IMS, WAS) provids tools and runtims to dvlop and invok Wb and REST basd srvics from applications basd on COBOL and PL/I IT rol (Bob) is knowldgabl about this SW stack 2. Sharon: Dvlopmnt and managmnt of Entrpris APIs for xposing xisting ntrpris srvics Addrssing consumption and govrnanc of APIs Crat an API, discovr a suitabl xisting srvic, and assmbl this API from this srvic 3.

20 What is Srvic Discovry? Idntifying an xisting srvic for prforming a spcific intndd businss function, and gtting dtaild dfinition of th srvic 1. Idntifying: Sarching, browsing, undrstanding and vntually, slcting a srvic from a st of srvics Qurying to rtriv a list of matching srvics Browsing information on rtrivd srvics Gtting additional dtails as ncssary in undrstanding a srvic Slcting a srvic whn a srvic is dmd a good match 2. Gtting dtaild srvic dfinition: Rtriving various dtails of a slctd srvic Srvic schma and dscription (.g., WSDL or JSON) for API dfinition Gtting additional tchnical dtails for API assmbly including dtails on runtim invocation and scurity protocols

21 Why is Discovring a Matching Srvic Challnging? Idntifying a srvic or cod for rus Nd to nsur that th cod prforms th intndd functions for th consuming application A good srvic documntation nds to includ not just th tchnical dtails on th intrfac, but also th smantics of th trms, constraints on us, and dscription of businss functions it prforms Evn for cod rus by th sam dvlopmnt organization, nds to look back at th associatd businss rquirmnts, unlss ky information is codifid as associatd businss mtadata,.g., businss classification of transactions, such as Paymnt, crdit, tc.
