# Acquired Some Of These For Cheap: Can I Use Them and How Many Are Enough?

Welcome back to our blog, dear sysadmins and homelab enthusiasts! Today, we’re delving into a common conundrum many of us face when setting up or expanding our self-hosted environments: What can you do with the hardware you’ve acquired on the cheap, and how many are enough? Let’s dive into this topic, focusing on key aspects such as homelab setup, Docker deployment, Linux servers, and open source alternatives.

The Acquired Hardware: Making the Most of It

First things first, let’s clarify that the hardware you’ve picked up at a bargain can indeed be put to good use in your self-hosted environment. Whether it’s an old server, some spare storage drives, or even a couple of extra RAM sticks, every piece of equipment has its purpose.

Server Roles and Responsibilities

When deciding where to allocate your acquired hardware, consider the roles your servers play in your homelab setup. For example:

• File server: If you’ve got some extra drives, these can be repurposed as a file server for storing and sharing data.
• Application server: An older server could serve as a platform for running applications, be it a web server, mail server, or database server.
• Docker hosts: Don’t forget that with the rise of containerization, your servers can double as Docker hosts, allowing you to deploy and manage multiple applications easily.

Homelab Setup: Scaling Up (or Out)

When it comes to scaling up or out your homelab setup, the acquired hardware can play a crucial role. Here’s how to approach this challenge:

1. Vertical Scaling: This involves adding more resources to an existing server (e.g., adding RAM or storage drives). It might not always be feasible with older hardware, but it’s worth investigating first.
2. Horizontal Scaling: This refers to the addition of new servers to your homelab setup. With the acquired hardware, you can create new servers for specific roles or even create a cluster for improved redundancy and performance.

Docker Deployment: Maximizing Your Resources

Containerization offers an excellent way to make the most out of your acquired hardware. By deploying applications in containers, you can reduce resource waste and ensure that each application only uses the resources it needs. With tools like Docker Compose, managing multi-container applications becomes a breeze.

Linux Servers: Choosing the Right OS

Linux servers are a mainstay of self-hosted environments, and your acquired hardware is likely to be running some flavor of Linux. When choosing an operating system for your servers, consider the following factors:

1. Support: Pick an OS that offers long-term support, ensuring security updates and stability over time.
2. Performance: Different Linux distributions have varying performance characteristics. Ubuntu Server and CentOS are popular choices due to their reliability and performance.
3. Community: An active community can be invaluable for troubleshooting issues, finding solutions, and staying up-to-date with best practices.

Open Source Alternatives: Embracing the Power of Free Software

Lastly, let’s touch on open source alternatives for common self-hosted applications. Not only do they offer functionality comparable to their commercial counterparts but also foster a collaborative spirit and promote innovation in the tech community. Some popular open source alternatives include:

1. Nextcloud: A secure, open source alternative to Dropbox and Google Drive.
2. OwnCloud: Another open source file hosting platform, similar to Nextcloud.
3. MariaDB: An open source database management system that’s a drop-in replacement for MySQL.
4. nginx: A lightweight and efficient web server, often used in place of Apache.
5. Docker: While not an application itself, Docker is a must-have tool for containerization and deployment in self-hosted environments.

Wrapping Up: Making Informed Decisions

In conclusion, don’t shy away from using the acquired hardware in your homelab setup. Be mindful of each server’s role, consider vertical and horizontal scaling options, embrace Docker for efficient resource management, choose a suitable Linux distribution, and explore open source alternatives when possible. Happy tinkering!
