4. 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

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

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

33. 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…

34. …pets vs cattle:
build the experience
buy the logic
outsource services…

35. …with high growth comes high expectations:
100% uptime
100% flexibility
100% scalability…

36. …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

38. 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

39. …there are no big pureplay retailers…
so we are on a much bigger journey
…ok! there’s one
