@Al_Grigor Agent are amazing but they should never have permissions to apply changes in production, be it infra of product code changes. Tests and checks are now more important than ever. One agent makes a change another checks it, and then a human checks a second time.

Claude Code wiped our production database with a Terraform command. It took down the DataTalksClub course platform and 2.5 years of submissions: homework, projects, and leaderboards. Automated snapshots were gone too. In the newsletter, I wrote the full timeline + what I changed so this doesn't happen again. If you use Terraform (or let agents touch infra), this is a good story for you to read. alexeyondata.substack.com/p/how-i-droppe…

@TheLaranox @SimonHoiberg Surely, there are countless ways they could have optimized Kubernetes, but they chose to move to a simpler platform instead. My point was just to correct the notion that “Fargate should never be cheaper than EKS unless you’re doing something wrong.”

@CapitalFAITH @SimonHoiberg I'm definitely not advocating that k8s is for everyone just highlighting that if you can cut your bill by 2/3rd going from EKS to Fargate you were clearly doing something wrong with Kubernetes

I'm using Kubernetes to run my products on Hetzner. But not because it needs to scale - but because it's super practical. Whenever I hear people say "Kubernetes is overkill" they always talk about it from a "scale" perspective. My reasons: I want staging/sandbox + production environments, and I want a smooth deployment process. I push to a branch on GitHub, a pipeline starts, new code is deployed, old code is gracefully shut down, traffic is pointed over. Like I'm used to with PaaS. Kubernetes + Helm does this super well! This would be hell to automate with just docker and various manual scripts... But of course, you can overengineer just about anything and ramp up cost... That isn't specific to Kubernetes. Kubernetes can be just about as simple as you want it to. I think this is misunderstood 👇

Kubernetes migration almost killed our startup. Where we were: - 8 EC2 instances - Ansible for deploys - Boring but working - $1200/month AWS bill Why we migrated: - New investor wanted 'cloud-native' - Engineers wanted K8s experience - Competitors were using it - Seemed like the future 6 months later: - 3 engineers spending full-time on K8s - AWS bill at $4500/month - Deploys took longer than before - More outages, not fewer - Product development stalled We rolled back: - Moved to ECS Fargate - 2 week migration - Back to $1800/month - Engineers back on features K8s is amazing for scale. We weren't at scale. Technology should solve problems you actually have.

@TheLaranox @SimonHoiberg Also without AWS EKS add-ons, you'll still have to deploy replacements. Custom ingress, storage, cert management etc. every feature runs as a pod you pay for. Kubernetes is great but it's not for every org.

@CapitalFAITH @SimonHoiberg There is overhead to running K8s cluster But still typically less expensive when deploying like for like. Still gotta pay for obs on fargate and cloudwatch is famously expensive. If cost sensitive remove many add-ons e.g. don't need argo can use helm which is "pod-less"

@TheLaranox @SimonHoiberg There are no absolutes ECS will infact be cheaper for most depending on scale and strategy. Cloudwatch is not a must for monitoring, logs and metrics can use most observalibility platforms. How are helm charts getting applied without a CD tool?

@TheLaranox @SimonHoiberg ECS Fargate is often cheaper for many workloads. On EKS, you pay for the EC2 running add-on pods, observability, ArgoCD, Kube-system pods and $72/month for managed control plane. There's also a pod limits per node. Cost ultimately depends on your workload, scale and architecture

@SimonHoiberg Honestly I think that post is rage bait. Fargate should never be cheaper than EKS unless you're doing something wrong. That's the whole point of ECS fargate, you manage zero infra but you pay extra for that privilege. Sounds like they got skill issues!

Company spent $18k/month on Datadog. Leadership loved the dashboards. I dug into what we actually used: - 12 people logged in per month - 89% of metrics never viewed - Alerts had 97% false positive rate (team ignored them) - We were ingesting 2.4TB of logs daily - Retention: 180 days (compliance needed 30) Moved to: - Grafana + Prometheus (self-hosted) - Loki for logs - PagerDuty for critical alerts only - 30-day retention New cost: $340/month (hosting + PagerDuty). The controversial part? Engineers initially hated it because I killed their "observability theater." But incidents got resolved faster because we only tracked what mattered.

Exactly! It’s easy to mess things up with general purpose languages. HCL is less flexible but maybe that’s actually a feature. The inconsistency with using other tools is too wide, some folks even write their own layer of abstraction ontop of Pulumi or CDK. Not worth the stress in my opinion.

@CapitalFAITH @mitchellh That's definitely a reoccurring theme amongst devops, which is fair enough, and understandable. There's a path to writing declarative code when using general purpose languages, but it does take some effort to avoid a leaky declarative abstraction, in both cases.

Terraform is still the best. But I'd like to see someone replace it. The major alternatives aren't interesting to me cause they're too iterative and copycat. I want to see fundamentally new ideas take hold. IaC feels stagnant.
Adam Dingman@adam_dingman

@mitchellh If YOU had to build in the cloud today, would you pick up Terraform or something else?

@FrancoC137 @mitchellh Most Ops folks don’t want to write infrastructure in imperative languages like Go/Python. This is the same reason I think Ansible won.

@oluvvafemi @jorgemanru @dhh @jasonfried This is massive, being top 6 out of 1600 is no joke. It’s truly a proof of your ability and skills. I’m sure any org will be lucky to have you. Great job!

So I made it to the final 6 out of ~1,600 in the 37signals hiring process. They said my exercise + PR note showed "good taste." Unfortunately, the last two seats around the campfire were already taken. Good luck to the new hires and thanks @jorgemanru, @dhh, @jasonfried for a transparent process.

@GergelyOrosz @Pragmatic_Eng Thanks for clarifying! I was indeed surprised at first. The cloud is so complex most devs don’t even want to deal with it. I was really curious to see how a startup that size functions without an infra/DevOps/SRE team or person.

Got the part wrong on Cursor not having an infra team: they DO have an infra team that owns infra for product, ML and core stuff (as most startups/scaleups with their scale do!) Removed the original tweet - and will share more details in a deepdive to come in @Pragmatic_Eng

Well, we actually did it. We digitized scent. A fresh summer plum was the first fruit and scent to be fully digitized and reprinted with no human intervention. It smells great. Holy moly, I’m still processing the magnitude of what we’ve done. And yet, it feels like as we cross this finish line we are instantly at a new starting line. I’ll have more to share about what’s in store that we’re building on top of this. A huge HUGE congrats to the entire team across scientific, engineering, operational, and creative disciplines. It takes a village named Osmo to do this. I don’t know if this is embarrassing, but I carry the plum scent with me a lot of places and smell it constantly. It makes me smile. I’m curious, if y’all want to smell it? If we made a limited release fragrance of the first teleported scent and dedicated the proceeds to science, would you want it?

I have two exciting pieces of news to share! Firstly, I have taken on additional responsibilities at @Cloudflare and will now be responsible for Developer infrastructure as well as Developer productivity going forward. Secondly, I'm hiring! The spec says remote US, but I'm open to candidates in London, Lisbon and Amsterdam too. I know I spend most of my time talking about Go, but this is very much a platform role so I'm looking for someone with experience building developer tooling and is comfortable with Kubernetes. We do use #golang a lot though ;) The spec is here: boards.greenhouse.io/cloudflare/job… DM me if you have any questions and I'll do my best to respond! :)
