+## A little about me and the past
+
+- I work professionally as a "DevOps" engineer at Elsevier with a focus on Kubernetes and containers
+- Previously a JavaScript developer, now a Go developer
+- I've been running my own servers for as long back as I can recall (historically cheap VPS's with applications running either directly on the OS or using Dokku)
+- I like to tinker with "Smart Home" stuff
+
+---
+
+## Where things are at today...
+
+* **87** uniquely identifiable devices connected to my home network
+* A Zigbee network with **32** devices
+* A single-node Kubernetes cluster running on a dedicated desktop machine hosting **14** applications
+* An autoscaling 1-3 node Kubernetes cluster hosted on Scaleway running **~30** applications
+* 1 Raspberry Pi running Home Assistant to control all smart devices in my home
+* 1 Raspberry Pi running OctoPi to control my 3D printer

+
+**FTTP** - Zen Internet

+**Powerline**

+**Router** - TP-Link Archer C7
+↯
+**Mesh WiFi beacons** - TP-Link Deco M4 (x3)

+**87 devices**

+<!-- _class: lead -->
+
+## Local Network setup
+
+4 devices connected via ethernet
+
+Everything else via WiFi
+
+All devices have static IPs and assigned hostnames
+(based on the periodic table of elements)
+

+
+## Kubernetes - local
+
+An old desktop machine repurposed as a single-node Kubernetes cluster
+
+**OS**: Ubuntu
+**Kubernetes Version**: Microk8s v1.20.1
+**Specs**: CPU - 4 core | Memory - 12Gb | HDD - Lots
+
+---
+
+## Kubernetes - local
+
+**Primary Use**: Hosting sensitive or local-specific applications that I want to keep off the internet.
+E.g.
+
+- custom built CCTV monitoring application covering the 8 cameras I currently have set up
+- automated download tools so I can kick off downloads remotely while I'm out
+- DNS-based ad blocker (AdGuard)
+
+---
+
+## Kubernetes - cloud
+
+Hosted on Scaleway's managed Kubernetes platform, Kapsule.
+1-3 *DEV1_M* instances, autoscaled based on load.
+
+All defined in code using Terraform and stored in git.
+
+**Kubernetes Version**: v1.20
+**Specs**: CPU - 3 vCPUs | Memory - 4Gb | HDD - 40Gb + 14 PVCs of varying size
+
+---
+## Kubernetes - cloud
+
+<style scoped>p, ul { font-size: 0.9em; }</style>
+
+**Primary Use**: Hosting internet facing services and providing a secure, authenticated tunnel to my local cluster
+E.g.
+
+- My personal blog plus some related sites
+- Self-hosted alternatives to cloud services: Gitea, Nextcloud, Harbor, Photoprism, etc.
+- Tekton - handle all my CI/CD needs, triggered by webhooks from Gitea
+- "Utility" applications to make my life easier:
+  - Convert SVG to DXF - used when creating 3D print designs from SVG
+  - website-to-remarkable - lets me send a webpage as a PDF to my reMarkable tablet for later reading

+# Personal Infrastructure
+
+A casual talk given at [Not JSOxford](https://not.jsoxford.com/) on 10th February 2021 about my personal infrastructure setup, my smart home devices and how I make use of Kubernetes for a bunch of stuff.
