Final answer:
Agent-based orchestration requires a proprietary agent to be installed on every device, making setup perceived as more complex. Agentless orchestration does not require such installations, potentially making deployment simpler and less expensive.
Step-by-step explanation:
The key differences between agent-based orchestration and agentless orchestration lie in their deployment and operation methodologies. Agent-based orchestration requires proprietary software to be installed on each device, which facilitates the management and monitoring of those devices. This installation typically grants the orchestrator a higher level of control and detail over the managed devices, but it can introduce additional complexity regarding deployment. Agent-based setup is perceived as more difficult because it involves this process of installing an agent on every device.
On the other hand, agentless orchestration does not require a proprietary software agent to be installed on each managed host. This can make deployment simpler and often quicker since there is no need to deal with individual installations on a per-device basis. This approach often utilizes standard management protocols such as SSH or WMI to interact with devices. As such, agentless orchestration is generally considered simpler and potentially less costly regarding the initial deployment.
