Go Serverless, Compute Only
When it Matters!

2. The Monolithic Architecture

3. 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

4. The Microservices Architecture

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

CTO - Amazon

$ chalice new-project helloworld
$ cat helloworld/app.py
from chalice import Chalice
app = Chalice(app_name="helloworld")
@app.route("/")
def index():
return {"hello": "world"}
$ chalice deploy
...
Your app is available at: https://endpoint/dev
$ curl https://endpoint/dev
{"hello": "world"}

40. Alexa, Hello!

41. 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

42. 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);
};

44. 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
