“Microservices”


Need an “API for the Internet” Any Device, Any Service


“Representational State Transfer is the software architectural style of the World Wide Web.” Roy T. Fielding

REST – A Key to Cloud Computing

Or put another way…

REST is an architectural style to defining,

publishing and consuming APIs and

services on the internet using HTTP.


REpresentational State Transfer (REST)

• Model resources, not actions:

– GET /ords/hr/employees/ …GOOD

– GET /ords/hr/GetAllEmployees/ …BAD

– Use nouns, not verbs

• Uniform operations on all resources:

– GET, POST, PUT, DELETE, OPTIONS, HEAD

– Many nouns, just a few uniform verbs

• Stateless requests, state transitions communicated via hyper-links. – IT'S ALL ABOUT THE HYPER-LINKS

The Architectural Style of the Web

REST


Oracle REST Data Services HTTP(s) API App-Dev with Relational Tables in Oracle Database

{ “custno”: 1001, “name”: “Scott King”, “address”: “500 Main street, Innovation CA”, “orders”: [ { “orderno”: 404, “orderdate”: “Feb 27, 2014”, “status”: “in process”} } } { “orderno”: 303, “orderdate”: “Feb 26, 2014”, “status”: “in process”} ] }

JSON

HTTP(s)

https://myhost/myapp/hr/customerorders/1001

Oracle REST Data Services

SQL

ORDS maps standard URI requests to corresponding relational SQL (not schemaless): e.g. SQL SELECT from customers and orders table. ORDS also transforms the SQL results into the highly popular JavaScript Object Notation (JSON), other formats include HTML, binary and CSV.

Fully committed to supporting any and all standards required by Fusion / SaaS / FMW; we are actively engaged in the ongoing dialog.

Oracle REST Data Services Example: Query returning JSON for customer 1001

{ “custno”: 1001, “name”: “Scott King”, “address”: “500 Oracle Parkway, Redwood Shores, CA, 94065”, “country”: “USA”, “class”: “A”, “orders”: [ { “orderno”: 303, “orderdate”: “Feb 26, 2014”, “status”: “in process”}, { “orderno”: 202, “orderdate”: “Jan 16, 2014”, “status”: “processed”}, { “orderno”: 101, “orderdate”: “Dec 2, 2013”, “status”: “processed”} ] }

http://myhost/myapplication/custorders/simplequery { custno: 1001} • Map URI request to data access template • Bind custno (1001) to bindcustno • Execute select statement below • Note embedded cursor expression • Set format to JSON

JSON Result

select c.*, cursor( select * from orders o where o.custno = c.custno) orders from customers c where c.custno = :bindcustno

The Two Biggest Disruptions To The Enterprise

CLOUD Has transformed every facet

of the IT infrastructure

MOBILE Has transformed every facet

of modern society


With Growth Comes Challenges for the Enterprise

18

Growth

Challenges

No integration across apps & backend systems

Not easily portable to other development environments

Not customizable to your business needs

Lack of secure access

Limited views into productivity… no analytics

Harder to maintain, not upgrade protected

Custom APIs give you the chance to take the ugly, horrible mess of on premise legacy enterprise endpoints, combined with 3rd party web services, and turn them into optimized endpoints for mobile consumption.

Custom APIs • Beyond prebuilt Platform APIs

• Build your own Custom APIs

– Define RESTful endpoints

– Implemented in Node.js

– Consume Connectors

• Expose through Mobile Backends

– Can be reused

– Protected by roles

The mobile developer & service developer work hand in hand in parallel. Or 1 person does all the work in sequence.

The choice is yours.
