PERFORMANCE EVALUATION OF DEPLOYING MICROSERVICE SUSING DOCKER AND PODMAN

Containers are the latest generation of virtualization solutions. \u91The most popular container solution has been Docker, but it struggles with security issues. A newer alternative is Podman, which solves the security issues while off\u82ering similar functionality. In this study I answer the question ”how does the overhead of Docker and Podman impact performance compared to native performance?”. Th\u91e amount of overhead these two containers introduces are compared, along with native system performance by benchmarking CPU- memory- and disk performances.\u91These benchmarks implies that the two containers have very similar and near-native performance and the choice of container solution is not a question of performance, but rather of user preferences: Do you want the added security? Podman. Do you already have your whole environment build around Docker and the security is not a problem? Stick with Docker
