AWS Case Study: mytaxi
ECS, Docker, ELB, SQS, SNS, RDS, VPC, and spot instances. Pretty canonical setup these days...
The mytaxi app is also now able to predict daily and weekly spikes. In addition, it has gained the elasticity required to meet demand during special events. Herzberg describes a typical situation on New Year's Eve: “Shortly before midnight everyone needs a taxi to get to parties, and after midnight people want to go home. In past years we couldn't keep up with the demand this generated, which was around three and a half times as high as normal. In November 2015 we moved our Docker container architecture to Amazon ECS, and for the first time ever in December we were able to celebrate a new year in which our system could handle the huge number of requests without any crashes or interruptions—an accomplishment that we were extremely proud of. We had faced the biggest night on the calendar without any downtime.”

Charity Majors - AWS networking, VPC, environments and you
'VPC is the future and it is awesome, and unless you have some VERY SPECIFIC AND CONVINCING reasons to do otherwise, you should be spinning up a VPC per environment with orchestration and prob doing it from CI on every code commit, almost like it’s just like, you know, code.'

VPC Flow Logs
we are introducing Flow Logs for the Amazon Virtual Private Cloud.  Once enabled for a particular VPC, VPC subnet, or Elastic Network Interface (ENI), relevant network traffic will be logged to CloudWatch Logs for storage and analysis by your own applications or third-party tools.

You can create alarms that will fire if certain types of traffic are detected; you can also create metrics to help you to identify trends and patterns. The information captured includes information about allowed and denied traffic (based on security group and network ACL rules). It also includes source and destination IP addresses, ports, the IANA protocol number, packet and byte counts, a time interval during which the flow was observed, and an action (ACCEPT or REJECT).
