If you are already pretty proficient in coding, I would take a break from it and instead learn something different.
- Sport (Snowboarding/Skiing/Swimming, Climbing etc lessons)
- Reading books (History, Biographies, etc)
- Visit a new town (doesn't have to be too far) and hangout with complete strangers and learn their stories.
Or purely on the STEM side you could refresh yourself on probability, statistics, linear algebra and get a deeper grasp on machine learning/data science.
I have noticed that all google cloud services now require credit card information for validation. Can this be be made optional and instead rely on their Gmail accounts ? (Especially for people just wanting to tinker with new services for fun)
I suspect that it's unlikely that google can remove this because bad guys tend to spin up many free trial instances and do bad things (sharded bitcoin mining, DDoS'ing, etc). Privacy is #1 so they aren't allowed to look inside your machines or inspect your traffic...so that leaves billing / such metadata to fight abuse.
That makes perfect sense, and I don't argue with this logic at all. But since you're here, I'd like to say something (that isn't horrible :P) that I've actually wanted to [have the opportunity to] get out there about GCP for a while now.
The "Heroku-style free" tier is likely to be all I can manage for the short to medium term future, due to a variety of factors.
As a result, the two go-to systems I would turn to if I need code hosting are Heroku and OpenShift, and I have accounts with these platforms (although I'm leaning toward the latter lately). I am yet to do anything generally interesting with them myself, but these are the systems I take into account when talking to others, because I have no experience with GCP. (I wonder if this is true for others too, and how big that number is.)
I have zero idea how Heroku are fending off precisely what you refer to. I've heard about situations where individuals' AWS accounts have been hacked by automated systems that spin up "instances with everything", but once it was established with billing that the account was hacked, the charges (which in one case were 5 figures) were fully reversed. Perhaps this fact is relevant here.
I think the problem can be solved before it (theoretically) gets to that point, however.
Serving up webpages, doing the occasional database transaction, etc, produces a significantly different CPU load than bitcoin mining does. I don't consider instance CPU usage monitoring a violation of my privacy, so I think it would be perfectly fair to throttle back continuous high CPU usage, but allow for short bursts of high usage. (In fact, I think this kind of thing is already standard...?) For bonus points, make the system track instance CPU usage and adjust its thresholds to allow for periodic high burst usage :P (since, thinking about it, masquerading as a web server and doing 30 seconds of mining every 5 hours is going to work out to zero gain).
I wouldn't consider it at all unfair to offer a free tier with exceptionally aggressive CPU-time QoS; in fact, it would probably suit me (and a lot of other people) perfectly, giving the funemployed community the option to do things like spin up fascinating new environments like Erlang, Dart, Rust, etc, and play with these environments (which are not yet available on Google's cloud hosting infrastructure) for web serving and similar. (For more bonus points, I'd extend the heuristic CPU-time tracking I mentioned before to classify instances as "friendly" over the long term, and let them have exceptionally low latency! :D)
In short, there's a whole demographic of people out there that you're definitely excluding, including people like myself who are just at the "messing around" stage, to nervous types who don't like deadlines and run from the "free for X period of time" part of GCP.
I realize and recognize that your response here is only your opinion, not Google's, and I'm very happy to respond here or via email (my address is in my profile) if you'd like to discuss any of any of the things I've said. ^^
If you are not hurting for money(which I doubt), I would suggest taking a nice break, travel, pursue some other skills like new language(Spanish, Portuguese), photography, cooking, volunteering, adventure sports. It will recharge you and maybe along the path you will find some interesting problems you could solve, for an instance a software solution for a problem that exists in some foreign country but you dont see the same problem in US.
$2k for 15000 users. <wrong>Each user is worth $7.50/month to you. But, they only pay once to sign up.</wrong> Each user is worth 13 cents.
So, it seems that the users paying for the archival service($25/yr) are the one's keeping the lights on at your bookmarking service. 1000 such users would bring in $25K. Basically you need 7% of your users(15000) to break even today.
Each user is worth $2000/15000 ~= 13 cents
My Question:
1. Is it easy to get recurring paying users?
2. In the long run(for any paying web service) what % of the user base do you think will be such users ? [Is 20% the max ? or 30 % ?]
Did you mean to compute the cost/user? If so, that comes out to a little over 13c/month. Still, that comes to $1.60/year, meaning that a user would start to cost money right around the end of the 6th year of usage (assuming hosting costs don't go down).
But if they're not paying for archival, are they really the folks who are causing the high hosting costs? As other have speculated, it would seem that the archival service might be the major reason that hosting is so expensive.
