What can Minecraft teach us about the adoption of cloud native technologies?

A

Okay, we are excited to kick off our first ever CN CF event here in KITT, in Sydney, in Australia, can I just get a quick show of hands how many of you have been to a cube con before in San, Diego or Shanghai or Amsterdam last year, great? Well, a pretty small number less than 10%. We definitely hope that this will be kind of a taster or maybe a sort of gateway drug that will get you to go mainline. The real thing.

A

Let me tell you a little bit about this space, so CN CF is the organization that hosts these open source projects and organizes both cube con and also these kubernetes forums advance. We also publish the cloud native definition quote: cm CF s-- goals is to organize state of the art to to provide democratization of state of the art patterns. In order to make these innovations accessible for everyone Matt. Could you try and fix that note screen for me? Please?

A

Oh actually, I got it here so anyway, I want to share with you a short parable about this democratization, but first I need to introduce my family. We live in New, York City, where my wife Julie is a climate scientist.

A

She couldn't be joining me for this trip, but her climate change, forecasting, startup, Jupiter intelligence uses, kubernetes and I will just mention here how devastating we all find the fires and and seeing the impact of climate change and unfortunately, here's an example where Australia I think is leading having to face these challenges that the rest of the world will soon enough. So this is our younger son Ellis who's 10 and throws a solid fastball. Our older son Adam just became a teenager, and this is our cat poros.

A

Now, when Adam was a seven-year-old second grader, a bunch of his friends started playing Minecraft, so I installed it on his iPad. In a week later, I found Adams sitting on the couch, but with an iPad screen instead of books and no little brother and with a frightened expression like this, but the strange part was that his iPad screen was black. Why are you staring at a black screen? I asked I'm hiding from the zombies, he replied, I, don't see any zombies. I said the zombies come out when the Sun sets he explained.

A

The screen is black. He said because I'm hiding in a hole in a hill, you see minecraft, might look like this during the day, but at night the zombies come out and my second grader had not yet learned any of the ways that he might defeat zombies, but he had figured out that he could dig a hole with his hands and close it and around himself until the screen went black.

A

This story is a metaphor. The second grader represents most enterprises.

A

Although kubernetes crossed the chasm last year, the majority of all enterprises are still not cloud. Native zombies represents software failures, specifically anything that can cause downtime hiding in a hole represents precautionary practices such as long release, cycles, infrequent dependency, updates and manual quality assurance now, I want to emphasize that for both second-graders and for most enterprises they are not acting irrationally. The zombies are real. Precautionary practices are a reasonable response.

A

I also want to make clear that in comparing enterprises to second graders I'm, not exempting my own organization CNC F is part of the Linux Foundation. We host software, including Linux nodejs and let's encrypt and yet projects we've undertaken like an open-source CEO, a bot have been delayed.

A

The solution for my second grader Adam was to arrange for the older sibling of a classmate to come over a fourth grader and the fourth grader taught us about crafting tables. You know how, when you combine software development with information technology operations, you get DevOps well. Similarly, minecraft consists of mining and crafting, and my second grader had learned how to mine all on his own or at least how to dig with his arms. But he didn't know how to craft and crafting is critical to the whole game.

A

Let's take a look at a simple crafting example: take a pumpkin, some sugar and an egg, and use your crafting table to combine them into a pumpkin pie yummy, but not so useful.

A

So, let's do a more complex example that will help us stop zombies, chop a tree to get wood which you form into wood planks and then used to make a stick, kill a spider using a bow and arrows to get some string now dig and gravel to find flint and kill a chicken to get a feather and finally combine these using a crafting table to create a bow and some arrows. As long as you ignore the circular depends here.

A

The lesson of Minecraft is that you could take simple things and combine them together into more complex things, to build very powerful tools, and here at kubernetes forum, sydney we're doing the same thing. As you probably know, kubernetes uses the firewall technology iptables to manage networking connections between pods IP tables, of course depends on Linux and specifically the networking subsystem. The first Linux firewall IPFW originated from BSD. It was soon replaced with IPFW ADM, the Internet Protocol firewall administrator, which was more complete and easier to use.

A

This was reimplemented as IP chains, which was then superseded by IP tables as part of the net filter system. It is now being reimplemented using EBP eff, the extended berkeley packet filter, which has an awesome logo, so firewalls are a core building block of kubernetes which have been crafted into more advanced forms over time, but so are C groups and the domain name system and the raft distributed consensus algorithm implemented in MCD.

A

In fact, kubernetes is built on hundreds of foundational technologies that have been combined together, but I would go a step further and argue that kubernetes itself is like a crafting table. It is a kind of alchemy that turns simpler things into more powerful ones. Kubernetes, in short, is like minecraft. You have all the tools you need. You need to build, what you want and even tools to build new tools, but what we construct is up to us.

A

Finally, where do the fourth graders and the second graders come together to share their crafting formulas? The answer is kubernetes forums and, of course, cube con. Please raise your hand now. If this is the first kubernetes event, you've ever attended Wow about two thirds. You are the metaphorical second graders and, what's the benefit for the fourth graders, there are two first after we got educated about crafting. My son Adam gave the fourth grader a cookie know. I mean a cookie.

A

The metaphorical fourth graders in the audience, who can provide assistance to those second graders may find that they are showered with cookies, and you know, job offers in the second and even more important reason is that the second graders will soon enough become fourth graders and our community, where democratization is a core value, is eagerly looking for people who can contribute new and improved crafting ideas.

A

Kubernetes is only five years old, which means that we are all still in elementary school I, look forward to seeing what we will learn from each other. Thank you very much.
