Building infrastructure with Open Source - a TrueNAS and OPNsense walkthrough

Small to medium-sized companies face the challenge of deciding how much on-premises infrastructure is necessary. Self-host or put everything "in the cloud"? An increasing number of developers working from home does not make things easier.

When self-hosting products like storage appliances or firewalls, off-the-shelf solutions are frequently targeted at either home users or larger enterprises. I aim to present two open-source products that provide enterprise features while leaving the decision about the hardware size and investment entirely to the user. This way robust and scalable solutions can be built that match the company size and requirements while keeping the budget in check - for single developers up to large web agencies.
