Overview

Aptible VPC-based approach means that most stack components are not accessible from the Internet, and cannot be targeted directly by a distributed denial-of-service (DDoS) attack. Aptible SSL/TLS endpoints include an AWS Elastic Load Balancer, which only supports valid TCP requests, meaning DDoS attacks such as UDP and SYN floods will not reach your app layer.

​
PID Limits

Aptible limits the maximum number of tasks (processes or threads) running in your containers to protect its infrastructure against DDoS attacks, such as fork bombs.

The PID limit for a single Container is set very high (on the order of the default for a Linux system), so unless your App is misbehaving and allocating too many processes or threads, you’re unlikely to ever hit this limit.

PID usage and PID limit can be monitored through Metric Drains.
