4. What do we want to do?
Situation: we failed every time when selling hot tickets.
Goal: selling tickets smoothly on internet.
Possible solution: large-scale multi-tier system, only
possible by using cloud service

5. Why AWS?
Evaluation: stability, easy to use, scalability, billing method
Target: ISPs in Taiwan, AWS, and other cloud services
AWS: the most mature, stable, user-friendly and billing by
hour. Almost no differences where we host.

6. When we started it, we found
Much, much easier and faster for installation new virtual
servers than physical ones.
Much cheaper for building complex structure when using
small instances at the beginning.
Handling services easily like load balancing, moving to
RDS for MySQL, creating Read Replicas.
With good partners like
eCloudvalley we can reduce
exploring/troubleshooting time.

7. Stress testing and architecture adjustment
Starting with 10,000 t2.micro instances, it costs only
$0.013*10,000=$130 for one hour.
Write simple scripts to simulate users behaviors.
It’s much easier to redesign the whole system when
failed.
Relatively simple to rebuild the new system, and test it all
over again.

8. Using AWS products/services
High stability, availability, scalability, flexibility

12. Benefits with AWS
Lower cost for building larger structure.
Highly scalable, if you build it right.
Agility – you can fail faster, fail cheaper, fail forward
Helping us optimizing and lowering cost. Ex. RDS-
>DynamoDB, EC2->Spot/Block Spot.

13. 1.lower time of deployment: from 1,600 to 20 minutes
2.increase more than 130 times of resources in 30 minutes
3.handle 100,000+ concurrent users purchasing tickets
4.handle 70,000+ ordering requests per minute, max 2,500+ ordering
requests per second
5.have more than 30,000 tickets sold out in 3 minutes
6.pay less than 2 MacBook Pro to accomplish this mission
7.reduce our server cost to 0.26%
8.Accept IOPS from 20 to 135,000 (average number in every minute)
9.by using DynamoDB easily
By moving to AWS, we can
