ChatGPT's answer to: "What is Network Automation?"
Knowledge sharing has come a long way. The first transatlantic message was sent in 1858 (by the UK’s Queen Victoria to US President James Buchanan) and for the next 150...

Network engineers often have nightmares about data center migrations. Not only can it take months to complete a migration, most organizations will face multiple network outages during that timeframe. Today’s networks consist of hundreds of thousands of components that will need to be discovered, verified, and documented. In fact, two out of every three organizations face unexpected application disruptions during a data center migration project.

Organizations that are leveraging automation are sleeping easier at night, knowing that the most tedious and risky parts of the project can be handled without any risk. NetBrain can help you avoid critical roadblocks across three phases in a data center migration project.
Phase 1: Pre-Migration Network Assessment
The first step in any migration is to understand the ins and outs of the network. This is a comprehensive, yet critical process for any network team. This includes an:
By automating the network documentation process, organizations can streamline this process for both pre-upgrade and post-upgrade networks. Dynamic Network Maps have virtually infinite detail to document any aspect of design from firewall policies and dynamic routing to multicasting and layer-2 design.

Phase 2: Configuration Change Planning and Testing
By leveraging NetBrain as the center of a data center migration, network teams will be able to handle all the following items:
Typically, organizations will migrate a network and then troubleshoot problems after it’s already up. Organizations that use NetBrain can discover and map the simulated network to visualize and validate every configuration. For example, engineers can check key application flows and routing table changes. This will allow engineers to proactively guard against misconfiguration and reduce any outages after the migration. Once network teams feel confident about their planned changes, NetBrain can help execute them automatically to save time and avoid human errors.
NetBrain can visualize and validate every configuration.
Phase 3: Post-Migration Network Operations
Once the network is migrated, network teams need to ensure that it is running smoothly. Any migration will lead to small changes in the network, making troubleshooting much slower and less reliable.
NetBrain provides the tools for network engineers to create Executable Runbooks for enhanced troubleshooting and remediation of issues with the ability to view the entire network through a single pane of glass. This allows any changes to have minimal impact on network performance and troubleshooting.
Data center migrations don’t need to cause nightmares. When the proper tools are in place the process can be managed smoothly and with little to no anxiety.
