HeyJaredBetween the Clouds Newsletter
Deep dives into virtualization, home labs, and modern infrastructure, including cloud. From Proxmox to Docker Swarm and Kubernetes, to AWS and Azure. I share hands-on guides, real-world builds, and experiments from my own lab.

Why it is not enough to just have VLANs for network security (opens the original)
Read excerpt
If there is one networking construct that is in the middle of just about any network configuration, it is the VLAN. VLANs provide the layer 2 boundary that is the starting point for network security. They are a great starting point, but they are not ALL you need. VLANs in and of themselves don’t filter traffic, especially between different networks. Let’s see what is needed in addition to this.What a VLAN is and isn’tA VLAN is essentially a boundary for the purposes of a “broadcast domain”. So a
Why Self-Service Portals for Proxmox Are Getting Easier (opens the original)
Read excerpt
Self-service portals are a great way to allow developers and others to have just the right amount of access to a virtualization environment where they can control the lifecycle of their resources they are using for development. And, at the same time, it prevents having to give them full access when they only need to manage their own workloads. Self-service is definitely the answer, but it can create challenges. Let’s look at this and also tools that make it easier.Why self-service is important,
Make sure your Proxmox Storage Monitoring is not Lying to you! (opens the original)
Read excerpt
If you are like me, you are taking advantage of a lot of open source solutions for monitoring in your home lab. This includes running Grafana to monitor various things in the home lab. I currently monitor my backup solutions, Proxmox itself, and I recently added TrueNAS to the mix in Grafana. However, I realized it is worth a sanity check to make sure you are monitoring the right things and your metrics are what they are supposed to be.Why monitoring your storage is a good ideaStorage monitoring
How I benchmark my storage in the home lab (opens the original)
Read excerpt
When I go to add storage in my home lab, I want to know that the speed that I am hoping to get is what I am actually achieving in the home lab. Without proper benchmarking and testing, you won’t really know for sure. This is why I usually benchmark from “inside” a test VM. It measures the path that my actual VMs are using and this helps to catch issues before you put the storage in production.Create a disposable VMThe first thing I do is create a test Linux VM that you can have enough CPU and me
Are you scanning your container images for vulnerabilities? (opens the original)
Read excerpt
We do security scans across a whole range of different endpoints and technologies, but often container images are the construct that gets missed. Often containers are this “thing” that most view as just a self-contained black box that we don’t have to really look “inside of” and that containers negate any type of security concern. However, making sure you add image scanning to your list of things to check can 10X your security posture.Why container image scanning is neededContainers are great be
