REWORK
Kubernetes - What Do We Really Need?
"We're getting out of the cloud, in part because we want our independence," he says. "The downsides are just too much for us." The company is now using a new system called Kubernetes to run its own apps.
In October 2022, 37signals announced they would transition off cloud services in a post titled "Why We're Leaving the Cloud."
Despite the advantages of the cloud, the downsides were too significant for the company. In this follow-up episode to Leaving the Cloud on REWORK, co-founder David Heinemeier Hansson and Director of Operations Eron Nicholson discuss the progress 37signals has made since they decided to leave the cloud.
Listen in as they delve into the pros and cons of using the cloud versus owning your hardware and some of the misconceptions people have about cloud costs and expertise.
Tune in as the pair shares insights from their experience running web applications at scale and offer advice, tips, and tools for startups and businesses looking to optimize their infrastructure.
Join the discussion as they explore the importance of getting real about the costs of the cloud for small businesses.

[02:33] - David shares some tools that can be used to move out of the cloud, including Docker and Kubernetes.
[04:21] - Why 37signals opted for a new tool they built called Kamal to assist in their transition and their timeline for being entirely out of the cloud.

[11:08] - David discusses the criticality ladder they have in place to prioritize their move off the cloud, beginning with the lowest criticality app (Tadalist) before moving on to higher criticality apps like Hey, which deals with email and must always be available to users.
[13:23] - The app transition plan for the next few months.
[13:58] - Eron explains the challenges of staffing up for a project of this magnitude. He also highlights how many of their current AWS-related processes will become streamlined once they have their own infrastructure.

[23:17] - Eron shares how you can lease from vendors like Deft, Digital Ocean, or Hetzner until it makes sense for you to buy your own servers.
[23:46] - David discusses the importance of exploring alternatives to AWS, breaking the misconception that the cloud is the only option, and exploring the most cost-effective solution for your company.
[26:04] - David responds to a comment suggesting they could have saved money by optimizing cloud costs and the possibly "crippling" variability of cloud costs that is a major concern for smaller companies—a risk eliminated by owning your own hard
