What are your goals?

Racing within a window of time

4

Focus is on solving a problem

5

Skills are in Development not Infrastructure

6

Over-Engineering vs Re-Engineering

The Evolution of Architecture

8

The Monolith

9

Micro Services

10

API Driven Development

The Evolution of Compute and Storage

12

Physical Servers / Disks ->VM’s

13

Containers

Platform Level Services

My Application Challenge

Build a micro service based web application that…..

Scales per request

Requires no deployment effort

Fault Tolerant

Has a RESTful API interface with a Web client

The Catch

NO Servers

NO Monolithic App or Explicit Web Service

NO Explicit code for scaling and fault tolerance

And do it within 45 minutes…

What Services Could we use?

Static Assets in Amazon S3

Internet scale HTTP/S based object store

Inerently Highly Available and Fault Tolerant

Designed for 11 9’s of Durability

Can host static websites

Holds trillions of objects

Serverless micro services with AWS Lambda

Event Driven Computing service

Never pay for idle

Scales per request

Supports Node.js, python and Java (or other JVM based languages)

Event triggers from other AWS Services

23 different ‘Power Levels’ of AWS Lambda

A RESTful API with Amazon API Gateway

Host multiple versions and stages of your API

Create and distribute API Keys to your developers

Throttle and Monitor API Calls

Cache Responses

Transform Data

Generate SDK’s (Including Swagger Support)

Interact directly with AWS Lambda

A NoSQL Data Store with Amazon DynamoDB

Managed noSQL Data Store

Can be either a Document or Key/Value store

Simply provision read and write throughput

Enables you to focuss on your data

DynamoDB streams enables you to take actions on events

Inherently Highly Available and Fault Tolerant

Putting it all together

The Service Itself

Static Site in S3 www.servicecheck.com

Web Client API Gateway/serviceCheck

Lambda serviceLogger

Subtitle

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has a the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.

Here is an example: - Bullet Point one - Bullet Point one - Bullet Point one

It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

it looked like David sort of didn't want to be there. He

was shifting around on his chair like a man who'd just

nicked a Mars bar.”

Build small apps to help your DevOps


One more thing


Summary and Next Steps

Summary

Utilise Platform Level Services that have built in HA

Use a microservice approach

Use a common interface for services such as RESTful APIs

Store static files in Amazon S3

Use AWS Lambda as the glue between AWS services

Next Steps

Sign up for an AWS Account

Try out a new server-less service

Make use of AWS Forums and Support

Come and meet an architect at the loft
