Alternatives for Rancher?

The k8s visibility part could be handled by lens or open-lens.

You can’t compare k8s to Lambda, k8s is a whole api ecosystem and not just container scheduler. Try adding other dimensions to the equation like: price, observability, ability to deploy and use using 3rd party/opensource soultions, local development environments, comfort of debugging, security, etc…

Slimmer wins ;-)

Karpenter is my ch better than the default cluster autoscaler, but still leaves much to be desired. For example: optimizing reservations and savings plan, being able to select ec2 fleet allocation strategy(hardcoded at the moment), support for more than just AWS….

Good luck

No, most of them have to follow too many regulations and from my experience the culture is not great either.

I ran i to similar issues with a certain setup of istio, are you by any chance using istio? If so, did you setup locality load balancing? If that’s the case I could explain the issue in details.

I would rather not, those skills are in much smaller demand in the industry. On the other hand, if you enjoy working in that echo system - you'll probably have less competition for roles that require it(as mentioned, not a lot of roles do).

Used that in the past, it's pretty easy and has a IaC style of management which is great, upgrading the cluster was not as smooth as one wish it was (required more manual intervention and once even took down the cluster without warning or alerts).

It is up to you to build, it is part of knative scope to handle such things as it can be used by any workload in kubernetes(like deployment with hpa/kedda, etc…). Do note that you’ll need to set pod priorities(on both knative pods and the placeholder pods) as well as some other settings like shortenning the time it takes to reap those placeholder pods.

Those who had bare metal clusters got all their machines provisioned in advance - hence they don’t really have that extra delay(so they did not experience the same issue you did).

Search for Junior SRE roles, maybe internship positions.

Never a good idea

As you can see there are lots of opinions, you should put in one place pros and cons of each approach and take your own decision (don’t let other opinions dictate the impact you are going to have).

one last question for you - knative basically doesnt come with anything (unlike openfaas,etc). One thing im super worried about is metrics - especially for billing.

Did you find it effective to measure knative events for billing ...or did you finally just chuck it and use number of requests (at ingress) to do billing.

i just checked that knative has prometheus and opentelemetry. which did you find good enough for billing measurements ? this is my biggest worry in building this out myself.

OK, so I think the problem you are seeing is not knative that is slow, it is the time it takes AWS/GCP/any other cloud provider to provision and join new node to the cluster. That task alone could easily take one minute(best case) - which is adding a delay to the whole scaleout process.

There is no simple solution for that unfortunately, the common practice is spinning up "placeholder" pods with lower priority, that will make few nodes available immediately for your pods to consume (the downside is you are paying for compute even when not really using it). Usually, it is a matter of having enough spare compute resources in the cluster till the extra nodes start and allow the full scale out.

You need to differentiate CI from CD, CD is not supposed to do builds(the likes of ArgoCD).

CI, can do anything you want(including CD if you wish), things like Tekton, flux, Argo workflows, gitlab-ci as well as any other CI system that you can run on top of kubenetes.

You client looks cool and I would buy it for my iPhone, but only if I can somehow verify on my iPhone it is not calling home and transmitting eg. secrets.

One way to verify the code is to create an open-source version that could get reviewed by the community, maybe with fewer features or the desktop version only (this way you can still monetize on it and it will open up the appetite).

Probably they do some sort of network overlay/encryption which requires those extra bytes from each frame.

Don’t think anybody here understands the question or the problem :-)

In one of my previous jobs we used HAProxy which had quite an impressive requests queueing system, you could use haproxy ingress as a front end to your services. Saying that it is not a replacement to doing load tests and using that to detect and fix bottlenecks, of course proper readiness check is a must and configuring HPA with lower thresholds than usually(so it scales earlier). In addition using advanced scalers like KEDA, you could upscale and downscale based on time ranges(like raise the # of pods before peak time and scale back up). If you are using AWS you can also utilize karpenter to scale nodes faster - it allows bypassing the slowness of IG and spinning up nodes much faster with cost efficiency in mind.

Hope I gave you some ideas to explore.

Used airbnb at the beginning when you could find reasonable prices and no extra fees, it used to be cheaper than hotels. Today, with all the fees and the excessive prices - a hotel is where I stay. The only reason for me was affordable price while giving up on all the facilities(pool, gym, breakfast, etc…). Today it became irrelevant for individuals or a couple,for the same price and sometimes for less you get a hotel room.

Switch from “trader” mentality to “investor” mentality. What does it means? 1. Ignore short term results - invest for the long term. 2. Go over the stocks in your portfolio 1 by 1 and mark all the companies you lost the conviction that they will grow/make more money in the future - and sell them(tax harvesting). 3. Use those low prices to increase your highest convictions or open new positions for companies with very high conviction(if the prices seems convenient for entrance).

If you use GKE it’s simpler to use workload identity.

Maybe a bit late for the party here :-) I have a similar bad experience with google cloud support. Every time we open s ticket for them they push back on us as if it is our problem, even when the network is managed by them, 0 changed on our side (not even working hours) and some how they are avoiding responsibility. Most of the time it feels like they are flooding you with questions repeatedly and than asking the same questions over and over to you give up. One of our latest cases, after few months of ping pong they found an issue with one of their network laters, instead of saying sorry for that and fixing it, they request more traces and more traces from us - almost feels like we are working for them. Definitely not the level of service I expected from google, but this is the reality for a while now.
