Why should a business care about APIs? Why should you care?
60%
Salesforce.com has
a marketplace (App
Exchange) for apps
created by its
partners that work
on its platform;
they now number
more than 300
partners.
90%
Expedia’s APIs allow
people using third-
party websites to tap
its functionality in
order to book flights,
cars, and hotels.
The GoPro
Developer Program
provides toolkits,
APIs, technical
information and
support to enable
companies to
incorporate GoPro
connectivity into
their products.
In a thought market,
Go-pro is looking at
APIs enabled digital
engagement (i.e.
user generated
content) as means
to deliver value-add.
ref: https://hbr.org/2015/01/the-strategic-value-of-apis
60%
eBay to list its
auctions on other
websites, get bidder
information about
sold items, collect
feedback on
transactions, and list
new items for sale
— all of which give
additional exposure
to eBay items and
increase revenue.

What is a Microservice?

into manageable and independently
deployable components,

Summary
§ APIs bring tangible value to businesses
• And like doors, APIs are of different type, shapes and forms
§ Microservices Architecture provide a robust/lightweight/scalable/decoupled way to
implement APIs
• There are 3 aspects to microservices: architectural, technical, organisational
• Bounded Context helps shape microservice scope & definition
§ 3rd generation API platforms are microservice oriented and hybrid – not monolithic
§ Oracle API Platform Cloud Service (to be released very soon!) + APIary deliver a
pure play 3rd gen platform
§ Using APIary for API-first brings agility and simplifies process of designing APIs
and Microservices
