When it Matters!

The Monolithic Architecture - Antipattern
  Difficult to scale
  Single point of failure
  Not fault-tolerant
  Difficult to work across teams,
often slow to iterate on new
functionalities

The Microservices Architecture

Microservices advocate creating a system
from a collection of small, isolated services,
each of which owns their data,
scalable and resilient to failure

Dr. Werner Vogels
CTO - Amazon

No server is easier to manage…

…than no server.

AWS Lambda
…than no server.

The Power of Speech: Alexa
Alexa, the voice service that powers
Echo, provides capabilities, or skills,
that enable customers to interact with
devices using voice
Alexa Skills Kit (ASK) allows everyone
to build and publish their own skills
  Skills can be powered by AWS Lambda

The Power of Speech: Alexa
Node.js SDK available to quickly build new voice skills.
github.com/amzn/alexa-skills-kit-js
var AlexaSkill = require('./AlexaSkill');
var HelloWorld= function () { AlexaSkill.call(this, APP_ID); };
// Extend AlexaSkill
HelloWorld.prototype = Object.create(AlexaSkill.prototype);
HelloWorld.prototype.constructor = HelloWorld;
HelloWorld.prototype.eventHandlers.onLaunch = function (launchRequest, session,
response) {
var speechOutput = ”Hello World”;
response.tell(speechOutput);
};

Final Thoughts
  Use Amazon API Gateway to build a front-door to all your
microservices (AWS Lambda, Docker, EC2 etc.)
  Use microservices with polyglot persistence to avoid
bottlenecks, schema issues, quick iterations and allow
independent scalability (and caching)
  Create many version and stages – no additional charges
for APIs, allows for backwards compatibility
  Use serverless interfaces when possible – HTML5 and
JS frameworks like React or Angular are useful
