Many networks are now configured via a GUI - but there is real power in programming ability in the network. ![The Network as Code](https://blog.iptel.com.au/hs-fs/hubfs/Blogs/Network%20as%20Code/The%20Network%20as%20Code.gif?width=737&height=395&name=The%20Network%20as%20Code.gif) Network Programmability bridges the gap from legacy networking to modern networking, bringing back repeatability, automation and control while still enabling the convenience of cloud‑based management.

Whilst this had a quite steep learning curve, it made reusable templates easy to create and backups simple to maintain by copying config files to a backup location.![Boost Your Business Efficiency Meraki Managed Services Unleashed (Instagram Post)](https://blog.iptel.com.au/hs-fs/hubfs/Blogs/Boost%20Your%20Business%20Efficiency%20Meraki%20Managed%20Services%20Unleashed/Boost%20Your%20Business%20Efficiency%20Meraki%20Managed%20Services%20Unleashed%20(Instagram%20Post).png?width=250&height=250&name=Boost%20Your%20Business%20Efficiency%20Meraki%20Managed%20Services%20Unleashed%20(Instagram%20Post).png) With the move to cloud services, infrastructure is now managed through web interfaces. This has lowered the learning curve and offers a single management location for all network infrastructure. However, the downside this brings is that larger changes often require navigating multiple pages, slowing down bulk updates. Backing up configuration is also often very difficult, since the cloud services are redundant and no provision is made to simply copy settings. Although templates are sometimes provided to allow for configuration re-use, they’re often limited in how they can be applied, restricting per‑site customisation.

Solutions such as Ansible and Terraform have been created to hide the complexity of the API enable consistent configuration files across different platforms. These tools can be leveraged to manage network infrastructure, with tools like Terraform having plugins allowing them to manage solutions such as Cisco Meraki, and Cisco ISE.  ASSOCIATED BLOGS: - [Managed Services - Cisco Core](https://blog.iptel.com.au/managed-services-d6-cisco-secure-access) - [Managed Services - Full Stack Observability](https://blog.iptel.com.au/thousandeyes-managed-services) - [Cisco SDA Fabric](https://info.iptel.com.au/the-cios-guide-to-cisco-sda-fabric) --- ## Declarative changes One of the major advantages of tools such as Terraform, is the ability for the user to define the end state of the network.  ![Managed Service Customer Pain Points (Instagram Post)](https://blog.iptel.com.au/hs-fs/hubfs/Managed%20Service%20-%20Customer%20Pain%20Points/Managed%20Service%20Customer%20Pain%20Points%20(Instagram%20Post).png?width=250&height=250&name=Managed%20Service%20Customer%20Pain%20Points%20(Instagram%20Post).png)The tool then interrogates the current configurations and works out the changes required to achieve the end state. Historically, the network engineer would have to work out each command that they were going to apply so this reduces the workload to maintain the network. Since changes are only applied if there is a difference between the desired configuration and what’s actually applied, the tool can be used to check that no unauthorised changes have been made, and to quickly revert to the approved design if there is a difference. Since the network is defined in a set of text files, software version control applications can be used to manage the files. This allows attribution of changes, as well as easy roll-back should a change cause unexpected problem. Should the service ever suffer a catastrophic failure, all of the configuration can quickly be restored to a new instance.

Most of the tools allow templates to be built with default settings that can be changed on a per-site or per-device basis, allowing for consistent configuration settings to be applied across the network. ![Network as Code\_1](https://blog.iptel.com.au/hs-fs/hubfs/Blogs/Network%20as%20Code/Network%20as%20Code_1.png?width=554&height=139&name=Network%20as%20Code_1.png)Example Terraform configuration block for a Meraki MX ASSOCIATED BLOGS: - [Meraki Reporting](https://blog.iptel.com.au/meraki-reporting) - [Meraki Refresh](https://blog.iptel.com.au/meraki-refresh) --- ## The Network as Code: Summary Whilst the move to graphical user interfaces, such as web UIs has been a major advance in the day-to-day management of networks, some of the features of command-line management have been lost. Network as Code brings those strengths back, combining the usability of cloud platforms with the repeatability, automation and control that engineers have relied on for decades.
