Implementing NetDevOps (NDO-302)
Price:
Duration:
Imagine managing a network with tens of thousands of devices. The mere thought of centralizing this data might seem overwhelming. You know that if you did have a single source of truth and a testing network that was identical to your production network, then these things become possible:
- Test changes on a network that is configured identically to your production network.
- Test rollbacks on a network that is configured identically to your production network.
- Rollback changes in seconds.
- Know the configuration of all your systems in REAL TIME.
- Convert, upgrade, or change configuration in seconds.
- Testing is conducted thoroughly and with complete peace of mind using Cisco Modeling Labs, not on your production network.
- Yet, the cost of not doing so is far greater than you might expect.
Managing a large network, with its hundreds or even tens of thousands of devices, is daunting. The prospect of loading all that data into a single source of truth may seem too great a challenge, and you might be tempted to avoid it. However, the benefits of managing your network with a single source of truth and a testing lab that is identical to the appropriate portion of your production network are undeniable. This course will teach you how you can accomplish it.
