ArgoCD - Key Differentiators

ArgoCD - Key Differentiators

• Below are the key differentiators of ArgoCD:
  • ArgoCD Interactions
  • Scalability and High Availability
  • Security
  • Customization and Extensibility

ArgoCD Interactions

• User Interaction
  • Users interact with ArgoCD primarily through the API server.
  • The CLI and the web Ul communicate with the API server for application management.
• Git Interaction
  • Repo Server interacts with Git repositories to fetch application configurations.
