What Is a DevOps Agent and Why Do You Need One?
Learn about DevOps agents, their crucial role in CI/CD pipelines, and how they facilitate automated builds and deployments.
Understand the key differences between agent-based and agentless automation approaches in DevOps, including their pros and cons.
Answered by Hackerito Team
IT Automation can be implemented through two primary approaches: agent-based and agentless automation. While both methods achieve similar end goals, they differ significantly in their implementation, security implications, and use cases.
Understanding these differences is crucial for organizations implementing automation solutions, as the choice between agent-based and agentless can significantly impact scalability, security, and maintenance requirements.
Popular tools like Puppet (agent-based) and Ansible (agentless) demonstrate how each approach offers distinct advantages and trade-offs that need careful consideration.

The choice between agent-based and agentless automation depends on specific organizational requirements, infrastructure complexity, and security needs.
While agent-based automation offers more robust capabilities and offline operation, agentless automation provides simplicity and easier maintenance.
Organizations often benefit from implementing both approaches where appropriate, leveraging the strengths of each method for different use cases.
