Here's our take.

Short-Lived Certificates

Nice Pick

Developers should use short-lived certificates in dynamic environments where traditional long-lived certificates pose security risks, such as in cloud-native applications, container orchestration, and CI/CD systems

Pros

• They are ideal for scenarios requiring frequent credential rotation, like service-to-service authentication in microservices architectures or securing ephemeral resources in Kubernetes clusters, as they minimize the window for attacks and simplify compliance with security policies
• Related to: public-key-infrastructure, tls-ssl

Cons

• Specific tradeoffs depend on your use case

SSH Keys
