Technology Short Take 157

Welcome to Technology Short Take 157! I hope that this collection of links I’ve gathered is useful to someone out there. In particular, the “Career/Soft Skills” section is a bit bigger than usual this time around, as is the “Security” section.

Networking

• Interested in understanding how NAT Traversal works? David Anderson’s post on how NAT Traversal works should help.
• This happened a couple of months ago, but I don’t think I’ve linked to it in a Technology Short Take: the Envoy Proxy open source project announced Envoy Gateway, a “new member of the Envoy Proxy family aimed at significantly decreasing the barrier to entry when using Envoy for API Gateway (sometimes known as ’north-south’) use cases”.
• This is a slightly older article from Ivan Pepelnjak on using netsim-tools to build Vagrant boxes, but let’s be real—his stuff is kind of timeless anyway, right?

Security

• Tal Maor, along with Nirit Tyomkin, describe moving laterally between Azure AD-joined machines.
• Phil Stokes of SentinelOne describes some of the early security changes found in macOS “Ventura” (i.e., macOS 13).
• Falco recently (at the start of June) released version 0.32.0, which included a number of fairly significant changes. Read more Continue reading

All the Things a Service Mesh Can Do

Van Phan Van is a technical product marketing manager for Consul at HashiCorp. He has been in the infrastructure space for most of his career and loves learning about new technologies and getting his hands dirty. When not staring at his computer screen, he's sharing pictures of food to his wife's dismay. Even as service mesh adoption continues to grow, some organizations are still trying to understand the full extent of what a service mesh can and can’t do. They may not realize that a service mesh is not just another single-purpose tool, but one that addresses a wide variety of networking needs. A service mesh may actually help consolidate multiple existing tools to help reduce management toil and costs. Just take a look at these two multicloud network architectures. Automating and offloading network services and security-related capabilities onto a cloud-agnostic service mesh can help simplify management in multicloud environments. Multicloud architecture using cloud-vendor-specific networking solutions: Using a cloud-agnostic service mesh: Many service mesh products include service discovery, zero trust networking and load-balancing capabilities, while some other service mesh products extend even further to provide multicloud/multiruntime connectivity, network automation and north-south traffic control. Let’s take a look at the capabilities Continue reading
