Network automation has become one of the most discussed skills in networking. Some people describe it as the future of network engineering. Others make it sound like every network engineer suddenly needs to become a software developer. This creates a lot of confusion.
So, when people ask, “Is Network Automation Hard?”
Yes, network automation can feel hard in the beginning, but it is not impossible. Also, it is not only for programmers.
The real challenge is not to learn Python, Ansible, or Git. The real challenge lies in learning how to make a network that has been manually managed for years, and make it more reliable, consistent, and repeatable. But it is absolutely learnable.
Before getting into more details, let us first understand what network automation is.
What is Network Automation?
At a basic level, network automation means using software to perform network tasks that would otherwise be done manually. These tasks can include:
- Collecting device information
- Backing up configurations
- Pushing standard changes
- Checking compliance
- Detecting configuration drift
- Generating reports
- Managing inventory
- Testing network state
- Integrating with tools like NetBox, Git, Ansible, or APIs
Instead of logging into every router, switch, firewall, or controller one by one, automation allows engineers to perform repeatable work in a safer and more consistent way. But this is where many people misunderstand automation.
Network automation is not just about writing scripts. It is about creating a better way to operate the network.
Why Do People Think Network Automation is Hard?
Most network engineers do not start their careers by writing code. They start with things like:
- Routing and switching
- VLANs and trunks
- Firewalls and ACLs
- BGP, OSPF, and STP
- Troubleshooting outages
- Change windows
- CLI commands
- Vendor-specific behavior
So when automation enters the conversation, it can feel like a completely different world. Suddenly, people start talking about:
- Python
- APIs
- JSON and YAML
- Git
- Ansible
- NetBox
- CI/CD
- Source of truth
- Infrastructure as Code
For someone who has spent years working in CLI, this can feel overwhelming.
A common fear among the network engineers is: “Do I need to become a programmer now?”
That fear is very real. Most of the time, network engineers with no programming background ask whether it is possible to learn the basics of Python for network automation in a week or two. The answers are always mixed as they directly depend on individual to individual, but the practical message is clear: you do not need to become a full programmer at once, but you do need patience and consistent practice.
That is why automation feels hard at first. It is not just a new tool. It is a new way of thinking.
Want to Learn Network Automation Step-by-Step?
If you are confused about where to start with Python, Ansible, APIs, or automation tools, structured training can make the learning process much easier.
At PyNet Labs, students learn network automation with hands-on labs, real-world projects, and guidance from industry trainers.

What Actually Makes Network Automation Hard?
The hardest part of network automation is not always coding. In many cases, the harder problem is the network itself.
Most real-world networks are not clean. They are full of history. They have old devices, different vendors, inconsistent naming, manual exceptions, undocumented changes, and configurations that were added during emergencies years ago. This makes automation difficult because automation works best when things are predictable.
If every device is different, every site follows a different design, and every engineer uses a different naming style, automation becomes harder to build and harder to trust. Also, there are many network automation tools and APIs that are useful, but they do not automatically solve the deeper problem of inconsistent network design and operations. This is where many teams struggle.
They think the problem is: “We need a better automation tool.”
But often, the real problem is: “We do not have clean standards, reliable inventory, or clear processes.”
Automation exposes these issues very quickly.
Common Challenges in Network Automation
Most automation challenges fall into a few common categories.
1. Lack of Standardization
If every device is configured differently, automation becomes difficult. Templates work best when standards exist.
2. Poor Inventory
Automation needs to know what devices exist, where they are, what role they perform, and how to connect to them.
3. Legacy Devices
Older devices may not support modern APIs or structured data, making automation more dependent on CLI scraping.
4. Tool Confusion
There are many tools: Python, Ansible, NetBox, Terraform, Nornir, Git, CI/CD platforms, vendor APIs, and more. Beginners often do not know where to start.
5. Fear of Breaking Production
This is valid. Network changes can impact users, applications, and business operations. Automation must be tested and reviewed carefully.
6. Lack of Team Buy-In
Automation is not just a personal skill. It often requires team agreement on standards, workflows, documentation, and ownership.
Why Network Automation Is Not Impossible to Learn?
Even though automation can feel difficult, it is not out of reach. The biggest misconception is that network engineers must become software engineers before they can start.
That is not true.
Most network engineers do not need to build large software applications. They need to automate practical network tasks. This could mean:
- Backing up device configurations
- Collecting interface status
- Checking software versions
- Finding configuration drift
- Validating NTP, SNMP, or AAA settings
- Generating inventory reports
- Applying a small standard change
- Creating repeatable deployment workflows
These are not abstract programming exercises. These are network problems. And network engineers already understand the network problem better than anyone else. This is a major advantage for them.
A software developer may understand code, but they may not understand why a BGP policy change is risky, why a firewall rule needs review, or why a small routing mistake can affect production traffic.
Network engineers bring important knowledge to automation:
- They understand protocols.
- They understand failure scenarios.
- They understand business impact.
- They understand change risk.
- They understand troubleshooting.
- They understand how networks behave under pressure.
Automation simply gives them a better way to operate. So no, automation is not impossible. It is just a skill that needs to be built gradually.
Is It Too Late to Learn Network Automation?
No. In fact, this may be one of the best times to learn it. Many organizations are still early in their automation journey. A lot of networks are still managed manually. That means engineers who understand both networking and automation are extremely valuable.
And network engineers already have an advantage. They understand:
- Routing
- Switching
- Security
- Troubleshooting
- Change impact
- Business risk
- Real production behavior
A pure programmer may understand code, but may not understand what happens when a routing policy breaks or a firewall rule is pushed incorrectly. The best network automation engineers combine both worlds. They understand the network, and they learn enough software skills to operate it better.
Frequently Asked Questions
Q1. Is network automation hard to learn?
Network automation can feel hard at first, but basic Python, networking concepts, APIs, and regular practice make it easier over time.
Q2. Do I need coding knowledge for network automation?
Yes, basic coding knowledge helps. Python is commonly used because it is simple, flexible, and useful for automating repetitive network tasks.
Q3. What is the hardest part of network automation?
The hardest part is usually understanding existing network designs, device behavior, error handling, and safely applying changes without causing downtime.
Q4. Can beginners learn network automation?
Yes, beginners can learn it by starting with networking basics, Python fundamentals, simple scripts, lab practice, and tools like Ansible.
Conclusion
So, the final answer to the question “Is Network automation hard?” Yes, network automation is hard in the beginning. But it is not hard because engineers are incapable of learning it. It is hard because automation touches many areas at once, i.e., tools, processes, standards, documentation, culture, testing, and trust.
The good news is that you do not need to master everything immediately. Start small. Automate one task. Make it safe. Make it repeatable. Learn from it. Then improve.
