5. T2 Instances Family
The T2 family of instance types could be a good option
for development and test workloads, especially
continuous integration (CI) and automated testing. T2
instance types are also a fit for single-server workloads
where the server sits idle much of the time.

9. Spot Instances
New Resource-Oriented Bidding
EC2 will use this information to build the fleet using the most economical
combination of available instance types, looking for instances that have the lowest
Spot price per unit.
2 x r3.8xlarge
4 x r3.4xlarge
8 x r3.2xlarge
16 x r3.xlarge
32 x r3.large
Or something more complex and heterogeneous, such as:
1 x r3.8xlarge and 2 x r3.4xlarge
2 x r3.4xlarge and 8 x r3.xlarge
8 x r3.xlarge and 16 x r3.large

• 1Tb retrival in 1 day = $ 306.99
• 1Tb retrival in 4hs = $ 1840

11. Pitfalls
Undersizing your servers
- Build T1 servers that will spawn alarms constantly
- Jenkins build time up to the roof
- Rebuilding servers
Oversizing your servers
- Wasted CPU/Memory processing & storage laying
around
- RDS storage that will eat you alive
- Rebuilding servers
API hits
- R53 TTL & Health check nightmares
- Extreme monitoring gone wrong
- Read. The. Fine. Print.

12. Pitfalls
Know your infrastructure
“Hey! That team migration was amazing! Can’t
we just do the same and move our entire storage
to AWS?”
Understand your applications
“So, I’m thinking about moving Project X to AWS.
It should
be super simple!! It’s just a couple of APIs!”
Make your team know & understand that most
migrations are an architectural challenge
“Can it be done by next sprint?”
