Choosing Your First Project

DEV & TEST

Spin environments up and down on demand

Decouple development & test environments from operational constraints

Explore elasticity in a sandboxed environment

BACKUP & DR

Take part of your data or business applications step- by-step into non-

production DR use

Understand cloud dynamics and test during

controlled failover

PAIN POINTS

Provide solutions to challenges causing

undue cost or management burden

Avoid capital investment in data centres, minimise

impact of hardware or software refreshes, solve

scaling challenges

Plan, evolve & achieve your goals

PROOF OF CONCEPT

Understand services Test performance Architect for scale

Develop team capabilities

PRODUCTION

Implement monitoring Change management Security management

System backup & recovery Scalability

OPTIMISATION

Automate corrective actions Deploy & tune Auto-scaling Zero downtime deployments

Managing All of the “Undifferentiated Heavy Lifting”


Relational Database Service Easy to set up, operate, and scale Handles time-consuming database management tasks, such as backups, patch management, and replication Supports MySQL, MariaDB, Oracle, Microsoft SQL Server, PostgreSQL & Amazon Aurora

NoSQL Database Service Fast, predictable performance

Supports document & key-value data models Fully distributed, fault tolerant architecture

Amazon RDS

Amazon DynamoDB


Amazon SQS

Processing task/processing trigger

Processing results

Simple Queue Service Fast, reliable, scalable, fully managed message queuing service Transmit any volume of data, at any level of throughput

Amazon SQS

Amazon EMR

Elastic MapReduce Uses Hadoop, an open source framework, to distribute your data and processing across EC2 instances Integrates with other AWS services, such S3 & DynamoDB Supports the broad Hadoop tools ecosystem

we need a magic scaling system that copes with peaks of 50x normal now and 350x in future

A (little) bit about our tech strategy:

1. its web based,

2. its platform independent 3. it links to our other systems

…and 2008 was a turning point…

…pets vs cattle:

build the experience

buy the logic

outsource services…

…with high growth comes high expectations:

100% uptime 100% flexibility 100% scalability…

…evaluating AWS - Bustin’ the Myths

1. there are serious emerging competitors 2. no need to pre-scale 3. only web apps work on cloud 4. you can scale you existing software stack 5. you can build and forget the infrastructure 6. really big businesses don’t use AWS

why not run your business on a proof of concept?

wanted a short migration 12 weeks

compelling events drove this to 6 weeks removed existing CDN added in multiple availability zones and DR migrated my-sql to AWS aurora DB re-engineered caching architecture

the result…

…had a hard landing

…there are no big pureplay retailers…

so we are on a much bigger journey

…ok! there’s one
