#2 HIGH AVAILABILITY ●●○○

AWS building blocks

Inherently Highly Available and Fault Tolerant Services

● Amazon S3 ● Amazon DynamoDB

● Amazon CloudFront ● Amazon Route53 ● Elastic Load

Balancing ● Amazon SQS ● Amazon SNS ● Amazon SES ● Amazon SWF

Highly Available with the right architecture

● Amazon EC2● Amazon EBS● Amazon RDS● Amazon VPC

Highly available service architecture

#3 SCALING●●●○

Auto-scaling

Elastic Load Balancing

#4 LOOSE COUPLING●●●●

Service orientated architecture

● Move services into their own tiers/modules

● Treat each of these as 100% wholly separate pieces of your infrastructure and scale them independently

● Design everything as a ‘black-box’

● Decouple interactions ● Favour services with built-in

redundancy and scalability than building your own

Building applications from scratch

Migrating applications – from legacy hosting

Optimising existing applications

Review security

Right sizing instances

Decoupling for scale

Make web servers stateless

Is my data safe and under control?

Maintaining privacy and security of data

Your data won’t move unless you move it

You decide where to put your data

Encryption in motion or at rest

Trusted Advisor - automated cost optimisation & advice

How to avoid common mistakes

Billing Alerts

Pre-warm Elastic Load Balancing

Scale down as well as up

Make sure web servers are stateless

Don’t use ephemeral storage for critical data

If nothing else, remember
