Design for failure, and nothing will fail. Having a resilient architecture means that your application should be available for customers while also recovering from failure. Making your architecture resilient includes applying best practices in every aspect, in order to make your application recoverable. Resiliency needs to be used in all layers of architecture, including infrastructure, application, database, security, and networking.
From the security perspective, the Distributed Denial of Service (DDoS) attack has the potential to impact the availability of services and applications. The DDoS attack usually puts fake traffic in your server and makes it busy, so that, legitimate users are unable to access your application. This can happen at the network layer or the application layer. You will learn more about DDoS attack and mitigation in Chapter 8, Security Considerations.
It's essential to take a proactive approach to prevent DDoS attacks. The...
