Agent and Agentless Operations: What’s the Difference?
In configuration management, data collection and other IT operations, the terms agent-based and agentless get thrown around a lot. But the difference between them can be subtle, and it’s important to have a clear sense of the difference between them.
When you’re talking about computers or software, an agent is effectively a standalone software program that resides on a device. Importantly, they tend to come with additional “costs” like installing, maintaining or upgrading them, maybe even uninstalling them. Many times, that work can be automated from a central location if it’s possible to push that sort of work across a network. But either way, an agent — sometimes called a daemon — is a standalone computer program that performs tasks from a target device.
Agentless operations refer to accomplishing a task without installing a piece of software onto the target device. If you’re collecting data, this might be a program that queries the already installed protocols or products on the device. If you’re managing network configurations, it might be a daemon that pushes updates through pre-existing APIs.
Unfortunately it’s not possible to say which is the “better” approach — there are just too many security, efficiency, cost and performance tradeoffs between agent-based and agentless operations and approaches.
