Loosely Coupled Services

12

Loose Coupling

Reduce interdependency among components A component has little to no knowledge of any

other components

13 Loose Coupling

Advantages Easier maintainability and implementation Simplified testing and error tracking

Disadvantages Low performance, functionality Unstable

14

Loosely Coupled Services

Independent services with little to no knowledge of companion services

Creation of web applications known as “Mashups”

15

Mashups

16

Introduction to Mashups

Combination of multiple services Built using loosely-coupled services Creates a better or more useful service Usually quick and easy to create

17 The Mashup Process

Purpose of service Find source combinations Must have API Weigh out attributes
