The Short History Of REST As Prerequisite For The Cloud

1. WWW ITSELF: EARLY 1990S

  • Roy Fielding coined REST as part of his Ph.D. in 2000
  • The epic story is the creation of WWW that starts with 1990–1995
  • 4 Web Innovations
  • 1. URL
  • 2. HTTP (over prioritization)
  • 3. HTML (underestimating)
  • 4. Browsers bring this to Cross-Platform Mainstream, User-Friendly GUI

2. PRE-2000: THE SOAP YEARS

  • if you wanted to communicate online between applications/pages you had to use Simple Object Access Protocol
  1. specify the endpoint and POST their SOAP enveloped to that specified endpoint

3. 2000 THE DISSERTATION

  • ROY FIELDING: The Dissertation 2000
  • Architectural Styles and the Design of Network-based Software Architectures
  • Goal: create a standard so that any server could talk to any other server in the world
  • Roy Fielding was with the web from the beginning (authored HTTP and URL) and his dissertation in the midst of the dot-com bubble burst revolutionized the way we use the web today, as shown in https://www.crummy.com/writing/speaking/2013-RESTFest/

4. THE 4 PILLARS OF REST: U.S.CLIS.CACHE

  • REST has 4 principles U-S-CLIS-CACHE
  • U for Uniform Interface:
  • always HTTP verbs
  • always URI as resources
  • always HTTP response with a status and a body
  • Stateless
  • each request is self-descriptive and self-contained for the server to process it
  • Client-Server
  • clear boundaries between roles of requestor and responder
  • Cachable
  • unless denoted, a client can cache any representation
  • statelessness makes this possible
  • REST is anti-SOAP
  • REST is resource-based

5. REST AND WEB 2.0 (AND AWS)

  • eBay, Amazon and Flickr were the first to start offering these standard APIs to their systems in the early 2000s
  • And so, AWS is built on this initiative in South Africa and it is the beginning of the cloud
