This post reviews the steps needed to define and configure data center segmentation policies using Arista's CloudVision platform alongside the results of these actions in a lab topology.

While Day 0 planning and Day 1 deployment capture initial attention, Day 2 operations—ongoing monitoring, automation, compliance and optimization—account for up to 70 percent of total data center network costs. Without a proactive strategy, enterprises face rising expenses, outages and security risks. To reduce TCO and improve resilience, organizations are adopting AI-driven and automated platforms like Arista CloudVision and Cisco Nexus Dashboard to streamline Day 2 tasks. Investing in visibility, operational simplicity and intelligent automation is now essential for long-term success.
