## Recruitment & Staffing
|
||||||
|
|
||||||
|
> The background for this talk is a very bad experience in this sector
|
||||||
|
|
||||||
|
- "We want someone opinionated" -> No you don't
|
||||||
|
|
||||||
|
### We don't know how to recruit engineers
|
||||||
|
|
||||||
|
- How many rounds of interviews?
|
||||||
|
- Technical tests?
|
||||||
|
- Not allways show your real worlds skills
|
||||||
|
- Many different kinds that usually don't fit (telling a junior)
|
||||||
|
- Other fields don't do this
|
||||||
|
- Is there an accurate feedback loop?
|
||||||
|
- The anwer to the qustion "how was the interview process" usually depends if there is an result and the kind of result
|
||||||
|
- Many just try to follow fang
|
||||||
|
- Plot twist you are not fang, you are a small company
|
||||||
|
- Mostly tests resilience and not really technical skills
|
||||||
|
|
||||||
|
### We're not very good at training for the future
|
||||||
|
|
||||||
|
- Many companies "only recruit senior engineers"
|
||||||
|
- Junior engineers are sometimes viewed as a cost center
|
||||||
|
- But they are important:
|
||||||
|
- Force seniors to explain stuff better
|
||||||
|
- Force collobaration
|
||||||
|
- Are a bit like the usual clueless customer
|
||||||
|
|
||||||
|
## Teamwork
|
||||||
|
|
||||||
|
- Depending on the team size and skillset the requirements for leadership change (Lead Engineer vs Engineering Manager)
|
||||||
|
- Don't hang up on stuff like "this is our team's senior/junior engineer" - everyone servers a role that changes depending on context (everyone is )
|
||||||
|
|
||||||
|
### Agile is broken
|
||||||
|
|
||||||
|
- The core of agile is about
|
||||||
|
- Individuals&Interaction > Process&Tools
|
||||||
|
- Working Software > Documentation
|
||||||
|
- Customer collaboration > Contract negotiation
|
||||||
|
- Responing to Change > Following a plan
|
||||||
|
- Agile never planned for all of the meetings
|
||||||
|
- If you have to have standups: Keep them short with rules
|
||||||
|
|
||||||
|
## Bias
|
||||||
|
|
||||||
|
- Everyone has biases and uncontious biases
|
||||||
|
- Example: The doctor test "I went to the doctor" -> Most people assume a man
|
||||||
|
- AI results in the same stereotype "Draw a doctor" -> While man with glasses
|
||||||
|
- Reality usually contradicts these biases
|
||||||
|
|
||||||
|
## Coding
|
||||||
|
|
||||||
|
- In the old days we copied from stackoverflow, now we let ai do the copying
|
||||||
|
- If GenAI uses LLM it bases everything on past code, will we reach a point where noting is new?
|
||||||
|
|
||||||
|
## What can we do
|
||||||
|
|
||||||
|
- Be an empathetic human (by gut feel or just by asking others)
|
||||||
|
- Develop engineers
|
||||||
|
- Never say something is shit
|
||||||
|
- Treat AI as an unreliable colleague (never assume it's allways right or wrong)

## Background: The state of cloud in mauritius
|
||||||
|
|
||||||
|
- Cloud native is more cloud naive
|
||||||
|
- Government treated cloud as bad for a while
|
||||||
|
- People know AWS but not the cloud native ecosystem
|
||||||
|
- Bad uplinks due to sea-cables that tend to get broken from time to time
|
||||||
|
- Only one local cloud service provider and the big providers are "an ocean away"
|
||||||
|
|
||||||
|
## The Solution
|
||||||
|
|
||||||
|
- Idea: Use multiple homelabs across the island as availability zones or multi-cloud
|
||||||
|
- Goal: Orchestrate everything through kubernetes
|
||||||
|
- Plan: 3 Homelabs with at least 3 Nodes each that join one big cluster
|
||||||
|
- Tech: Longhorn Storage, Tailscale for connectivity
|
||||||
|
- Converns: Latency, Power-Cuts, Bandwidth, IP-Rotation
|
||||||
|
- Prod use: A startup wanted to use this for their workload and needed
|
||||||
|
- Tailscale exit nodes for external services
|
||||||
|
- GPU nodes for AI-Workload
|
||||||
|
|
||||||
|
## Q&A
|
||||||
|
|
||||||
|
- How is ingress handled (by me)?
|
||||||
|
- Migrate the control plane to the cloud provider and use their static IPs.
|
||||||
|
- Ingress allways starts at the cloud and routes over
|
||||||
|
- Why tailscale?
|
||||||
|
- Fairly reliable
|
||||||
|
- Pretty simple
|
||||||
|
- Handles routing
|
||||||
|
- How are you planning on scaling this setup?
|
||||||
|
- More friends aka more homelab locations
|
||||||
|
- Utilize Tailscale
|
||||||
|
- How are you handling image distribution?
|
||||||
|
- Bandwitdh is not that limited (200 Down)
|
||||||
|
- They just host their own registry for stuff
|
||||||
|
- What about the neighboring islands? -> Cool ideas
|
||||||
|
- How big is your local cloud community? -> 15 People at smaller meetups and 1600 at the yearly dev meetup
|
||||||
|
- How do you handle security in your setup?
|
||||||
|
- This is not the primary concern for the government
|
||||||
|
- Most locals banks/insurers have inhouse servers or stuff on aws
|
||||||
|
- Most of the time security is an afterthought
|
||||||
|
- What kind of hardware are you running on and how do you aquire it?
|
||||||
|
- The second hand market is not really a thing (or rather expensive).
|
||||||
|
- They usually just import stuff themselves
|
||||||
|
- Most Nodes are Dell Optiplex or Lenovo Thinkcenters
|
||||||
|
- How does longhorn perform over the 200mbit connection? -> Surprisingly good
|
||||||
|
- Is Starlink available? -> No and the government does things linke "let's shut down socialmedia before the election"

Yes that is a negative day.
|
This is the first day of Cloud Native Rejekts and the first time of me attending this event.
|
||||||
Why? Because the numbering of the days is based on KubeCon instead of the trip.
|
|
||||||
Why? Ask the sleep deprived version of me who started his trip to London at 3am...
|
|
||||||
|
|
||||||
But this is the first day of Cloud Native Rejekts and the first time of me attending this event.
