Agenda

•Overview of REST/HATEOAS•Delivering Powerful Software as a SPA•Challenge : Fast AND Furious•Solution - Pragmatic Design at Each Layer

REST / HATEOAS• REST - Client / Server, Stateless,

Cacheable, etc.. • HATEOAS - Engine of Application

State How do we do this , really?

Usual “Search” / Consumer Apps• Interface - Frontend Layer (UI) is

Deployed as Static Files from CDN• Software - Business Logic (API) is

Deployed as Stateless Services • Database - Persistent information (Data)

is any of SQL/NoSQL/Graph/Index/*• Systems - Different Applications

(Systems) are hosted in private/public/* clouds

Usual “Search” / Consumer Apps

• Interface 10,000 Users, 1,000 Simultaneous Searches

• Software 200-200,000 Results, Highlights, HQ Images

• Database8,000,000 Objects, 20-50 Related Docs

• Systems 40-50 Servers, 5 Apps, 2 Databases, Several Frameworks

Challenge - Fast AND Furious

Don’t. • Dictated by a balance of Team / Customer /

RealityDevelopers Need to be Okay Maintainers Need to be Happy

• Serving up the UI/API/Images Properly Special Web Servers for JS/HTML/CSSSpecial App Servers for to serve up

Interface - What Framework?

• Data Update Frequency dictates Caching/Concurrency

• Data Security dictates Authentication • Data Relevancy dictates Linkage• Data Need dictates Size

Software - Serving API

• Relational is still relevant. It's fast. It's reliable. It's related.

• NoSQL works, choose wisely. *** (Consistency vs. Reliability)

• Index is an index. Don't use it as NoSQL. (SolR/ElasticSearch)

• Some data changes, while other data doesn't. (Transactions vs. Records)

Database - The Middle Path

• Criticality Influences Everything Mission / Business / Health Critical?

• SLA / OLACustomers have “Service Level Agreement” Functional Groups have “Operational Level Agreements”

• Commercial support means you can blame people and get them to fix it.If it breaks, you better own it, or get someone else to fix it, and pay them.
