TrueNAS Virtualization Solutions - Docker, LXC, and KVM - Which to Use | TrueNAS Tech Talk (T3) E051

Описание: On today's TrueNAS Tech Talk, Kris and Chris will revisit the three virtualization technologies that you can use to run non-storage workloads on TrueNAS - Docker, LXC, and KVM. How do they impact performance and functionality, and which one's right for you? They'll also tackle some viewer questions about VDEV removal, and make suggestions around L2ARC and Special VDEVs for a user building a budget system in the midst of RAMmageddon.

Chapters

00:00 Intro
00:36 TrueNAS and the Three Virtualization Technologies
01:48 Docker and LXC - Both are Containers, More Alike Than Not
03:05 Permanence and Updates - Docker is more Ephemeral
04:31 Docker Apps are Responsible for their Own Upgrade Logic
06:22 Bring Your Own Volumes - SSD, HDD, RAMDisk
07:25 LXC - Still Containers, More Freedom and Responsibility
08:26 You Can (and probably should) Still Map Extra Volumes
09:10 KVM - Full Virtual Hardware, Non-Linux OSes, New Kernels
10:15 "Use Docker First, LXC Second, KVM Third"
10:45 Docker - Simple to get started, still powerful when used properly
12:21 Pre-Packaged Docker Apps avoid dependency problems
13:13 LXC - Full Linux with more tweaking
13:59 KVM - Total Control, but with Complexity and Overhead
15:26 What about High Availability of virtual workloads?
17:08 App-Level Awareness is More Efficient than an HA/FT VM
18:28 What about Performance Differences between the three?
19:12 We're a Storage Company - Let's talk Storage Performance
20:11 Small Delays in Layers of Virtualization Add Up Fast
22:29 What about Network Differences between Docker/LXC/KVM?
25:22 Additional IPs and binding Apps/LXC to Specific IPs
26:22 Best Practice: Avoid Network or other Dependency Loops
