What’s New for Serverless

@heitor_lessa


Brief intro to Serverless


Build and run

applications

without thinking about

servers

… pay per request not

for idle

“ Scales with usage

Never pay for idle

High availability

built-in

No servers

to provision

or manage

A serverless world…


Serverless Applications

Services (anything)

Changes in

data state

Requests to

endpoints

Changes in

resource state

Event source Lambda function

Node.js

Python

Java

C#

Go


Common Serverless Application Use Cases

a.k.a In Case You Missed These Goodies!


AWS Serverless Application Repository

• Search and browse ready-made apps and samples

• Customize open-source apps to get started quickly

• Share apps privately or publically

• Monetize APIs using the AWS Marketplace

• All apps powered by AWS SAM


Concurrency metric in Amazon Cloudwatch

Per-function concurrency throttles

What you can do with it

1. Limit concurrency to legacy systems

2. Protect serverless production services

from other functions in the same account

3. Temporarily disable a function

4. Develop functions with limited billing and

“runaway” protection

Lambda – Concurrency controls

GraphQL APIs

Open, declarative data-fetching specification

!= Graph database

Use NoSQL, Relational, HTTP, etc.

Traditional data-fetching GraphQL

/posts

/postInfo

/postJustTitle

/postsByAuthor

/postNameStartsWithX

/commentsOnPost

/posts


GraphQL Spec - Schema

{

"id": "1",

"name": "Get Milk",

“priority": "1"

},

{

"id": “2",

"name": “Go to gym",

“priority": “5"

},…

type Query {

getTodos: [Todo]

}

type Todo {

id: ID!

name: String

description: String

priority: Int

duedate: String

}

query {

getTodos {

id

name

priority

}

}

Model data with

application schema

Client requests what it

needs

Only that data is

returned

Developer tooling


Developer tooling – SAM CLIAWS CLI tool for local testing of serverless apps

Works with Lambda functions and

“proxy-style” APIs

Deep SAM template validation and

project bootstrapping for all runtimes

Uses open-source Docker-Lambda images to

mimic Lambda’s execution environment:

• Emulates timeout, memory limits, runtimes

github.com/awslabs/aws-sam-cli


Developer tooling – CodeBuild Local Agent

Locally test and debug CodeBuild builds

Supports Artifacts, Curated CodeBuild images

and custom Docker images

docker pull amazon/aws-codebuild-local

docker run \-v /var/run/docker.sock:/var/run/docker.sock \-e "IMAGE_NAME=aws/codebuild/python:3.6.5" \-e "ARTIFACTS=/Users/myUser/build-artifacts" \-e "SOURCE=/Users/myUser/sample-app" \
