Agenda

System that respond to HTTP requests: Twitter API, Amazon S3 API, New York Times API

System that provides functionality through a standard interface: MySQL, Memcached, RabbitMQ, ...

What is a service?

Service-oriented design

Service-oriented design is about creating systems that group functionality around logical function and business practices.

Services should be designed to be interoperable and reusable.

Splitting up parts into components that can be iterated on, improved, and fixed without

having to test and verify all the other components when an individual is updated

or added.

Usually entails a trade-off between complexity and iteration speed.

Amazon AWS

Every piece of the AWS architecture is exposed as a web service, low-level system components exposed through

a services layer.

S3, SQS, SimpleDB, CloudFront, EC2

The Rails development style is all about quick iterations.

A Typical rails Application

The key to pairing Rails applications with services is to use Rails for its strengths

and switch over to services when a more stable approach is required

Service-oriented systems sacrifice iterationspeed for stability, reuse, and robustness.

Advantages of using services than a typical monolithic application:

Isolation...

Business Logic Isolation

Shared system isolation

Full Isolation

Testing in Isolation

Robustness

Scalability

Scalability on team and size

Reduces complexity in the codebase

Agility

Interoperability

Partitioning Functionality into

Separate Services:

Partitioning on iteration speed

Partitioning on Logical Function

Partition on Read/Write frequencies

Partition on Join Frequency

Versioning

• http://localhost:3000/api/v1/users/1

• http://localhost:3000/users/1?version=1

• http://localhost:3000/api/v2/users/1

DownsidesReleases dependencies nightmare

Smoke test suit mandatory

More moving parts and integration points

Trivial rails stuff gets harder

Failure tolerance is hard
