Dental and vanity surgeries aren't happening in a vacuum. There are baseline costs eg. anesthesia, recovery medications, medical machinery etc which are all bloated due to the rest of industry not being under price pressure (rising tid

Because insurance companies incentivize upward price momentum. The ones who innovate and bring the prices down are not rewarded for their efforts. Health inflation is higher than headline inflation because of this absence of price pressure

This is very good use case of micro-transactions. If AWS makes $100 off Redis, they should be pay back X% to Redis project, from which the money is distributed to contributors based on how important their contributions were. Also Redis proj

Is that really a problem in Cloud environments where you would typically use a Cluster Autoscaler? GKE has "optimize-utilization" profile or you could use a descheduler to binpack your nodes better

Wouldn't the network cost be absurd in such case? Not only the pod-to-pod communication cost skyrocket, all the heartbeats, health checks, metrics, daemonsets pinging each other will probably end up costing more than the CPU and Memory

GKE Autopilot is pretty much useless, very few cases where it actually turns out cheaper than simply using Cluster Autoscaler + Node autoprovisioning. Not only is the pricing absolutely absurd, they don't even allow normal K8s bursting

Datadog allows you to export all of this but I don't see how that's any useful. You can't really port Datadog dashboard to let's say Grafana easily. The query languages they use do not have 1:1 mapping, the way dashboard

How do you know the feeling(s) you are optimizing for are the right ones? A murderer is also optimizing for a feeling.

This is not a bare-metal vs Cloud comparison, the Cuber PaaS is supposed to run on anything including cloud based on their docs. So when they say "save 80% on cloud costs" I am assuming they mean for eg. save 80% on using Cuber on

GKE in general seems to be doing better than EKS though. They have a lot of things right and EKS seems to be playing catch-up. For example if you look at any Multi-cluster Kubernetes setup by AWS it's just a giant duct-tape rather than

It takes very long time for going from preview to actual production usage for anyone. We had T2D preview access more than a year ago, it took several months to get enough stock in Tokyo region (US always gets preference in such cases whenev

Yes, I point this out in the article too. Which CPU will perform better is heavily dependent on your workloads, so I refrain from relying 100% on synthetic benchmarks and directly ran canaries in production instead. It's definitely pos

The dead thing is Intel (x86) and the successor is AMD (x86) as opposed to ARM in our case. Isn't it correct?

Cloud world is really slow. Imagine writing about Zen3 Milan in Aug 2023 when AMD has already announced Zen4c Bergamo. Actually we were "ahead of the curve" since we got access to T2D before it was made publicly available in Tokyo

Thanks, that's a really insightful article! > Since you are using Go and targeting a specific modern CPU, you may also get a measurable benefit from setting GOAMD64=v3 That's actually a long pending open issue in our backlog :)

That is true. But in cloud our hands our tied, we cannot really switch from one one generation to another so easily. GCP has so far never launched a new chip while keeping the price same or lower. We did same cost/perf analysis on newe

We did a migration from GCP's Intel based E2 instances to AMD's T2D instances and saw huge 30% savings in overall compute! It is similar amount of savings folks got from switching to AWS Graviton instances, so looks like AMD might

Wouldn't the cost of cooking be higher depending on who you are? If one could spend few hours doing something that has higher ROI than eating pre-cooked food, then you are actually losing money cooking your own food.

There's nothing within the 5G spec itself that commands that every single cell site needs to be a massive MIMO supporting 1000s of users at once. Making a micro cell supporting just a family home is enough, then something a bit higher
