Concourse vs Vault: What are the differences?
Developers describe Concourse as "Pipeline-based CI system written in Go". Concourse's principles reduce the risk of switching to and from Concourse, by encouraging practices that decouple your project from your CI's little details, and keeping all configuration in declarative files that can be checked into version control. On the other hand, Vault is detailed as "Secure, store, and tightly control access to tokens, passwords, certificates, API keys, and other secrets in modern computing". Vault is a tool for securely accessing secrets. A secret is anything that you want to tightly control access to, such as API keys, passwords, certificates, and more. Vault provides a unified interface to any secret, while providing tight access control and recording a detailed audit log.
Concourse can be classified as a tool in the "Continuous Integration" category, while Vault is grouped under "Secrets Management".
"Real pipelines" is the primary reason why developers consider Concourse over the competitors, whereas "Secure" was stated as the key factor in picking Vault.
