Why you should have a homelab

7 Homelab Ideas | Why you should have a homelab (1)

In 1998 my friend Meredith gave me a RedHat Linux CD. I spent hours every day experimenting with Linux - I loved it. 2 years later I find myself in a room with 30 other students at a university who are applying for the same job as a computer lab technician - I think my chances are slim. Halfway through the mass interview, a man comes forward and asks if anyone has ever used Linux. I raise my hand - I'm the only one. He pulls me out of the interview for the lab assistant job and introduces me to the department head. You invited me to lunch. At the end of the day I had my first job as a sysadmin.

Learn things on your own and it will expand your possibilities.

One of the best ways to learn about systems, applications, and technologies is to set up a home lab. A home lab can offer you a fun, stress-free, and hands-on way to learn technology. A home lab will also help you find the technical areas that interest you. It is also convenient in that you can use it for your own home maintenance.

What is a home lab?

A homelab is an environment in your home where you can experiment safely.

It's a place outside of the corporate environment for personal projects, growth and a fun hobby. While not all Homelab projects result in professional development, many do.

The homelab environment for most technologists includes one or more servers running a virtualization environment and a storage solution to support various virtual servers providing services. Special home labs can also be built (e.g., a budding network engineer can build a home lab out of Cisco networking equipment).

Here are 7 ideas for your homelab

1. Router/Firewall

7 Homelab Ideas | Why you should have a homelab (2)

The most important device will be your router. I started with consumer routers that I flashed to DD-WRT/Tomato, then switched topfSense, DieUnifi Security Gateway, and now use aUnifi Dream Machine Pro. Here is my contribution tobester Gigabit-Router/Firewalls. Routers are great for learning about DHCP, DNS, VPN, firewalls, etc. I advise against using the router provided by your ISP, they are usually not very powerful and often not secure. In most cases, you can purchase a DSL or cable modem in place of the ISP-supplied modem along with the router. Another inexpensive physical router I would recommend is thisUbiquiti EdgeRouter X. Ubiquiti offers free software updates (their model is you buy the hardware and the software is free), and you get a handful of advanced features - it's a very capable business-class router and way better than your typical consumer router - to step up from Ubiquiti you would gopfSense, OPNSense, Juniper or Cisco.

2. Storage

7 Homelab Ideas | Why you should have a homelab (3)

The main reason I started my homelab was for storage. I took a lot of family photos and videos and wanted to save them. I know cloud services exist, but back then they were expensive, and then you kind of trust that provider won't delete all your photos or get bought out and shut down by a bigger company.

Then I started using themfree version of VMware ESXi. I needed faster storage with more IOPS. One of the best Homelab storage solutions isZFS. ZFS takes the best filesystems and the best of RAID and combines them into a software-defined storage solution that I've seen no hardware technology that compares to. Two popular free ZFS appliances that I like areNapp-It(based on OmniOS) andFreeNAS(now called TrueNAS).

I am currently using TrueNAS Core, iX System's free, open-source version of TrueNAS Enterprise, which is used by organizations of all sizes - from small businesses with a few TB of storage to large government agencies with PB storage. TrueNAS has done a great job of technology convergence. It's both aNAS and a SANSo you can try both storage approaches (I prefer NAS because it makes better use of ZFS, but many prefer to use SAN, and both have advantages and disadvantages), it also has many built-in storage protocols: FTP, iSCSI, NFS, Rsync server , S3 emulator, SMB (windows file server), TFTP, WebDav, it can join AD, it can even be an AD DC (if you like living on the edge), it has a built-in hypervisor (bhyve). Run VMs for anything you want. This is now marketed as hyper-converged storage. All of this is completely free. You can build your own or buy a small 4, 5, or 7 bay hot-swap systemTrueNAS Miniby iXSystems.

A few years after I learned ZFS for the home, my employer was looking for a new storage solution, so having that knowledge and experience helped. I found that one vendor with a traditional RAID solution was not properly addressing the RAID 5 write hole issue.

3. Virtualization

(Video) What's on my Home Server? MUST HAVE Services!

Virtualization allows you to run multiple virtual servers on the same hardware. There are two popular options for homelabs. Proxmox VE or VMware ESXi. I wrote about itProxmox vs. ESXiwhere I go into more detail. VMware ESXi is the king of the SMB hypervisor market, and VMware offers itsHypervisor free. The free version of ESXi is just like the paid versions, except that you cannot use some features (mostly related to high availability and failover with multiple servers). But you can learn most concepts and features from VMware. I'm looking at a hypervisor base infrastructure. From there, you can learn about other things like networking and storage, and play with any operating system or Linux distro you want.

Knowledge of VMware ESXi is an advantage, I have implemented it for several companies and one of my previous employers. And knowing how it works means I can intelligently discuss the VMware stack with the ops team.

see myFreeNAS on VMware guideif you are interested in running a FreeNAS virtual server in VMware.

Proxmox VEis another popular hypervisor – I run it in my home lab. For a free virtualization solution, you can't beat Proxmox. It offers you free high availability, Ceph storage clustering and live migration, which are paid features for VMware ESXi. I prefer Proxmox. But if you're on the fence and trying to learn for your career, stick with VMware. You won't find too many companies using Proxmox compared to VMware.

4. Networks

7 Homelab Ideas | Why you should have a homelab (6)

A home lab without proper networking will not get you very far. Luckily, if you use VMware, you can leverage it to use virtual network switches. For physical switches, I like the Unifi line of products. They're simple enough for a non-network engineer like me. Everything can be configured via the GUI. Unifi gives you managed switches, centralized management (with the Unifi controller), VLANs and PoE (Power over Ethernet), port trunking, port mirroring, redundant paths with spanning tree, etc.

7 Homelab Ideas | Why you should have a homelab (7)

I started with this little oneUniFi 8-Port-Switch (4 sind PoE-Ports). I also added oneUniFi 24-Port-SwitchThis allowed me to learn how to set up a LAG and configure VLANs across multiple switches (which was easy with the Unifi interface). I also like Unifi's philosophy - they sell you the hardware but the software is free - which means you don't pay for maintenance or support, you still get free updates. In a home lab, you might not need to freak out about VLANs, but it can make sense to separate your main network from your IoT devices.

(Video) What is a HomeLab and How Do I Get Started?

Learning how to set up VLAN tagging and link aggregation and understanding how networks work will help me communicate better with the network engineers when discussing design and deployment options - they might be using Juniper or Cisco equipment, but I know the concepts of their work.

5. Wireless Access Points

7 Homelab Ideas | Why you should have a homelab (8)

A robust wireless setup is also a necessity for a homelab. If you have a large house, you need to set up multiple APs and make sure they can hand off connections. i use thisUniFi 6-LR, which offers Gigabit wireless. These are managed by the same Unifi controller as the switches. I tried them first because I read that Linus Torvalds uses Unifi APs and they seem to be highly rated by tech pros - and now I don't think I would go back to anything else.

I wrote more about itUnifi gear here.

6. Network Monitoring

7 Homelab Ideas | Why you should have a homelab (9)

It's difficult to maintain a reliable network and application stack without monitoring for failures. There are hundreds of network monitoring solutions out there and it really depends on your needs. The most common solution isNagios. I had this at my home lab. Nowadays I useZabbixbecause it's simple and integrates with Ansible. Setting up centralized network monitoring can be a lot of work. One of the easiest to set up and most beneficial alternatives to centralized monitoring isnetwork data.

7. Infrastructure Automation

7 Homelab Ideas | Why you should have a homelab (10)

Automating your infrastructure might not make as much sense in a small homelab, but it makes sense to automate every task that you perform repeatedly, or a manual task that could be automated. For me, that was installing updates, provisioning servers, and renewing SSL certificates with Let's Encrypt. To manage this I useAnsibleThis is one of the most well thought out infrastructure automation tools I've seen. Ansible can manage Linux and Windows servers. Automating the learning infrastructure, especially if you do this with version control and CI/CD tools such asAzure-DevOps(You can get a free account for up to 5 users with unlimited private repositories) is a great thing to learn for your career if you are interested in the DevOps world. The book,Ansible for DevOpsby Jeff Geerling helped me get started. I suggest buying the eBook as he is known to provide updates to the book (not sure if he will continue to provide updates but just in case).

(Video) HomeLab Services Tour Late 2021 - What am I Self-Hosting in my HomeLab?

At work, we fully automated the deployment of Linux servers with Ansible - infrastructure as code. It took a month to invest, but it has really paid off as developers can now deploy VMware VMs however they want with Ansible by making a git pull request, our entire server fleet is updated automatically, and our servers and configurations are all consistent are. This replaced an old process of waiting several weeks for a VM to be provisioned and configured by hand.

Home Lab-Server

Depending on your budget and what you want in your homelab, you can use a repurposed desktop or you can put something as small as a Raspberry Pi on a rackmount server. You could get a rack of servers. I like the small microserver form factor. They are quiet, can be equipped with a powerful CPU, tons of RAM and plenty of storage space. But they are compact enough to hide under your desk.

Here are some options:

  • DIY Supermicro Minitower.You are small and powerful. Essentially a data center in a box. I have guides to create these based on thatIntel Xeon D, and theAMD EPYC. These can be built with lots of CPU and memory and with 4 storage bays, making them suitable for VMware ESXi, Proxmox VE or TrueNAS/FreeNAS. One feature I like about these is that they have IPMI/KVM over IP so you never need to connect a monitor or mouse. My homelab is equipped with 3 of these servers.

  • HP Microserver.If you'd rather not build it yourself, theHP MicroServer(Amazon) Series has a good selection of servers to choose from. I've seen people call their HP Microservers "Tardis" because they're so small for what they can do.
  • Raspberry Pi. Das CanaKit Raspberry Pi 4 4 GB Starter Kit(Amazon) would be a good start if you are on a budget and don't need a lot of processing power or need it in a small or remote location.
  • Rack-Server.If you're looking for rack mount servers (just to warn you the fans are loud) you can find good deals on eBay for used or non-leased servers or buddy your employer will get rid of one.

  1. Domain. Buy a domain for your homelab, even if you only use it internally. With a domain, you can get SSL certificates and not access devices over IP. I useFavorable nameAndCloud flareas a domain registrar and external DNS hosting.
  2. VPN. Set up a VPN so you can remotely access your Homelab. OpenVPN, Wireguard or ZeroTier.
  3. DNS filtering. Essential as the first line of defense to protect you and your family from malicious and inappropriate websites. See my post onDNS filtering.
  4. Dynamic DNS service– Your ISP probably gives you a dynamic IP. You can keep DNS up to date with your current IP, allowing you to access your VPN and servers remotely by hostname.DNS-O-Maticcan keep multiple DNS providers up to date.
  5. Passwortmanager– You should track your passwords with something like KeePass or LastPass.
  6. fuses– You want to make sure everything important is backed up externally with some cadence.
  7. version control– If you use an infrastructure management tool like Ansible or even need a place to store scripts, I suggest using a service like GitHub, GitLab or Azure DevOps to store everything.

Bonus homelab application server (vm or container) ideas...

  1. Minecraft Server- popular java game - it's like playing with Legos and a great way to get your friends together for some casual games.
  2. Mumble-Server– one of the best voice protocols for communication in the game.
  3. Emby Media Server- Anyone who has kids knows that those flimsy Blu-ray drives won't last long. It's great for storing and hosting movies, home videos, images and audio.
  4. Asterix PBX-Server– VoIP phone server (use Twilio or Flowroute for SIP trunking). Polycom makes great VoIP phones. With Twilio SIP Trunking, you can have a real landline number with E911 capability for a few dollars a month—and if you have multiple phones, you can use them as an intercom.
  5. Webserver- Start a blog! – I am hosting this blog from a server at my house. Nowadays, you can also use a service like Cloudflare to act as a CDN, which really reduces your bandwidth usage. Hosting your own blog is a great learning experience and gives you a place to log your Homelab experiments and share solutions to problems.If you blog about your homelab, please leave a link below in the comments.
  6. Automatic ripping machine- Upload all your Blu-Rays, DVDs and CDs to your Emby server
  7. backup server- I use FreeNAS/TrueNAS cloud sync tasks to back up my data from remote locations to home and from home to the cloud.
  8. pi hole.DNS server that can block ads for your entire network.
  9. Storj Node – Earn cryptocurrency by renting out your spare storage.
  10. BitcoinLightning-Knoten- Process bitcoin transactions for a fee.

Select one area at a time to get started.

There are many more areas than I've listed, but I think the above is a good starting point. Pick one area at a time - my homelab has been built up over many years - I often upgrade an area after a piece of equipment has failed or I need to replace it for some other reason - this is a great time to research.

(Video) 20 Ways to Use a Virtual Machine (and other ideas for your homelab)

If you're not sure where to start, choose the area that you like the most. For areas that don't interest you, the best you can do is do something different - you probably won't be good at something you don't enjoy. Of course, a home lab does not replace practical experience. But it does provide an environment to learn, experiment and improve your skills - and the great thing is that since it's your own lab, you can learn things that interest you.

I think that's the biggest advantage of a homelab. For me it's a playground. It is a place to put the love of learning into practice. It's a place of freedom. Nobody else dictates what you do here. It's a place where you can have fun while improving your skills.

Do you see a man skillful in his work?
He will stand before kings;
he will not stand before dark men. – Proverbs 22:29 NIV
