runc vs Kata Containers

Developers should learn runc when working with container technologies, especially for building custom container runtimes, debugging container execution, or integrating containers into CI/CD pipelines meets developers should use kata containers in multi-tenant environments, such as cloud-native applications or shared infrastructure, where strong isolation between containers is critical to prevent security breaches and meet compliance requirements. Here's our take.

runc

Pros

• It is particularly valuable for running untrusted workloads, sensitive data processing, or in regulated industries like finance and healthcare, where traditional container runtimes might pose risks due to shared kernel vulnerabilities
• Related to: kubernetes, docker

Cons

• Specific tradeoffs depend on your use case
