Johan Holder presents our checklist for deployment of web-scale applications on AWS. We cover the fundamentals you need to apply when moving applications from a legacy hosting provider or building new services from scratch. • How to architect your AWS environment to take advantage of specific services such as Elastic Load Balancing, CloudFront, Amazon SQS and S3. • How to build for scalability, resilience and security • How to manage your costs We also show you how to avoid the common mistakes we see organisations make when getting started with AWS.

17. #4 LOOSE COUPLING
●●●●

18. 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

19. Building

22. Is my data safe and under control?

23. Maintaining privacy
and security of data
Your data won’t
