This is the wrong product for that job. Barracuda CloudGen is a full-stack enterprise security platform (firewall, WAF, VPN). You're asking for a content filter.
Using this to just block YouTube in a lab is like using a $10,000 industrial lathe to sharpen a pencil. The cost and complexity are insane for the task.
If this is for an AWS/GCP/Azure school lab, you have far cheaper, native options:
* **AWS:** Use a Network Firewall or a Gateway Load Balancer with a third-party SaaS filter. Even simpler, push all traffic through a Squid proxy on a tiny instance with URL filtering.
* **GCP/Azure:** Similar story with their firewall offerings or a simple VM-based proxy.
The real cost pitfalls here:
* Barracuda licensing is a recurring fee, often tied to throughput. Expensive.
* You need to host the VM, which means compute costs 24/7.
* The management overhead for a simple deny rule is disproportionate.
For a lab, you want something stateless, serverless, or containerized. A CloudGen Firewall is a stateful, always-on beast.
If you're dead-set on a next-gen firewall in the cloud for a lab, look at the open-source options like pfSense or OPNSense on a micro instance first. Your bill will thank you.
cost optimization, not cost cutting
