You will learn:
- Why to be cautious with features like CRDs, StatefulSets, and Helm and how to evaluate if you really need them.
- How to stay on the "happy path" in Kubernetes by focusing on stable and simple resources like Deployments, Services, and ConfigMaps.
- When to consider alternatives like Google Cloud Run for simpler deployments that don't need the full complexity of Kubernetes.

With "Diet Coke Lover" Farrell
- Experience all aspects of Kubernetes on a smaller scale.
- Make practical decisions on networking, CNI (using Cilium), and distribution choices.
- Address security and persistent storage challenges in an on-premises environment.
- Encounter and solve "nitty gritty edge cases", particularly when using newer ARM hardware.
Daniel emphasizes that this hands-on method provides opportunities to "really think about how you're going to put things out, how to build things up from the ground, look at the tooling available and maybe even contribute" to the Kubernetes ecosystem.

A decentralized algorithmic crypto trading platform to revolutionize trading and investment with innovative technologies and automation??STAGE 3 Extension??Hello Everyone,We're delighted to share some exciting news with you!????First and foremost, we're pleased to announce that all dividends have been successfully released and paid to all investors in levels 1-8! This is just a taste of what's to come β moving forward, you can expect a dividend once per month from the profits generated by our algorithms through our AUM. We hope this news brings a smile to your face!????But wait, there's more! We've got another major update to share. We've recently sold off our entire Stage 4 token supply to an institutional client (family office). While they initially expressed interest in purchasing the entire supply during presale, they've settled for Stage 4 instead. Due to this exciting development and the numerous requests we've received, we've made the decision to extend the presale until Stage 3 sells out.??Currently, there are only around 30,000,000 ALGT tokens left in Stage 3. Instead of burning these tokens, we're offering you the incredible opportunity to purchase them at $0.08 each before we release the token on DEX for $0.15. This is your chance to get in early and secure your investment at a discounted rate!????We truly hope you appreciate these decisions as much as we do, and we're counting on your support to help us sell out this stage as soon as possible.????In addition to these developments, I am pleased to announce that the initial token airdrop is scheduled to occur within the next 10 days. This milestone represents the commencement of token distribution, a pivotal moment in our journey together.????We are deeply encouraged by these advancements and remain steadfast in our commitment to delivering value to our investors. Your continued support is paramount as we navigate this transformative phase.????Thank you for your confidence in our vision.Let's make this happen together!
