I have a deployed model on sagemaker with two production variants. I was wondering if you get charged for both variants even if I set all the traffic to just go through one of them.
The docs on pricing are found below but I couldn't seem to find the answer to this.
https://aws.amazon.com/sagemaker/pricing/
You will be charged as long as the model is running on an instance regardless of whether the traffic is going through it or not as still the model is running on an instance.
pardon me if this isn't the place to ask such question. But I have finished my project and thinking to deploy it using amazon elastic beanstalk and got a huge worry. My worry is that my project's database can be humongous. It's a community website like a reddit that users can create a page that other people can post text,link,pic,video(youtube). Also users get a profile page, and are able to comment as well. This was my first big project, and I don't want to pay more than $200 for server fee every month.
should I still deploy this? or just be happy I proved myself I can make this? how much do you think I'll have to pay assuming I get about (max)100 users?
For starters, you can look at the costs for any AWS service by going to that services 'homepage' and clicking "Pricing" usually on the left side. I typically get to the pricing page by Googling "AWS <> Pricing" (e.g. "AWS EC2 Pricing").
Whether or not you incur any cost and what that cost is, really depends on how you deploy your website. Questions like, is your database self-managed (i.e. installed on your own EC2 instance) or are you using RDS? Are you using S3 to store static content? Will you be serving your web contents via Cloudfront (AWS' CDN)?
Many of the basic services (EC2, S3, RDS, etc.) have free-tiers which will allow you to use them for free, provided you stay within certain (and usually very low) levels of usage.
If your database is going to get VERY large, and cost is your primary concern, it's usually more cost-effective to manage it on your own EC2 server, however then things like updates, security, scaling, backups, etc. all become your problem to deal with and often can incur additional cost (i.e. your backups will likely require volume snapshots which will cost you vs. RDS' backups are free).
If you're going to have a significant amount of static content, it will be more cost effective to host it on your own EC2 server, however again, all maintenance will be your responsibility, such as backups and scaling (which can incur cost) to meet demand vs. all of that is taken care of by S3, though you pay each time a file is accessed.
If cost is your primary concern, my suggestion is to start out your development using the AWS services (RDS, S3 maybe Elastic Beanstalk), though that can often complexity to your development efforts (dealing with authentication, additional SDK's, etc.). You can typically and pretty easily roll out your own service (MySQL, EBS filesystem to replace S3, etc.) as replacement. Additionally, again depending on your roll-out, there can be network traffic costs. Usually, this isn't a problem if you're doing things the way Amazon wants you to, but...it wouldn't be unheard of.
To get you started:
https://aws.amazon.com/s3/pricing/
https://aws.amazon.com/ec2/pricing/
https://aws.amazon.com/rds/pricing/
Additionally, there is a nifty calculator which can help you estimate your costs. You will need to know what your traffic expectations as well as service requirements are, but you can play around with those numbers.
https://calculator.s3.amazonaws.com/index.html
You don't have to worry about charges. As AWS has a Free tier which offers most of the services free for 12 months.
https://aws.amazon.com/free/
You can have 01 t2.micro (1 vCpu + 1 gb RAM) instance for Elastic beanstalk (EBS) with auto scaling turned off, purchase Reserved instances by making 1 or 3 year all upfront payment to save more.
https://aws.amazon.com/ec2/purchasing-options/reserved-instances/
You must use Relational Database Service (RDS) for database, instead of installing db in your EBS instance & store files on Simple Storage Service (S3).
RDS Pricing is $0.100 per GB-month, after first 12 months. So you dont need to worry about the database size.
After first 12 months, your monthly bill would be less than USD 50.
On production, we are using 2 t2.micro instances (Windows) with 1 Ms Sql database on RDS & we only have to pay for the extra EC2 machine, about USD 14 per month.
I did find some relevant information in the below stackoverflow thread which talks about the capabilities of t2.micro,t2.small & t2.medium ec2 instances.Do have a look at it.
several t2.micro better than a single t2.small or t2.medium
I aim to create an application that will be deployed thanks to Google App Engine.
Before that I would like to calculate the cost of Google App Engine.
For this I have to provide the Number of instances, per hour. How can caluculate this number of Instances ?
To reformulate, imagine I have 1 thousand users connected, how many users can 1 instance afford ?
Thank you for your answer and help

It's really hard to answer without more info. App engine consumption will depend on the nature of your app, the average session span and usage hours, how well you optimize your implementation and so much more variables...
Don't think about how many instances, think about how many instance hours you'll need to serve your users if you can figure how much you'll be consuming you could get an estimate using the App engine pricing calculator .
Completely depends on the code that runs on each request. You need to make it more specific to get a better answer. Ive had carefully implemented apps that receives thousands of requests per minute with a single instance. How long each request takes and the memory it consumes is key as well as the frontend instance type you select to use.
Appengine also lets you calibrate some parameters like min/max latency to control when more instances are launched.
Greetings,
I'm creating a multi-player android game and thought it would be a interesting idea to have App Engine handle the server work.
The game consists of 4 players, each phone requests an update every 0.5 seconds.
These requests are very simple and lightweight so i shouldn't be over reaching any free quotas.
The problem i found was that App Engine only handles 500 requests per second, i would only be able to
have around 60 game sessions active before App Engine will start ignoring new requests?
"App Engine's quota system allows for efficient applications with billing enabled to scale to around 500 queries per second (qps) or more than 40 million queries per day."
Or should i just not use this platform because it is not made for this kind of usage?
I sent this same question to the discussion groups on google but after 4 hours it hasn't been posted, there was no response on whether it was a bad question or anything. Hopefully someone here can give me some advice.
Thank you kindly, i'm looking forward to an answer and or advice.
Greetings,

That's an interesting question, considering the only page where I can find that quote contains the answer in the same paragraph.
http://code.google.com/support/bin/request.py?contact_type=AppEngineCPURequest
App Engine's quota system allows for
efficient applications with billing
enabled to scale to around 500 queries
per second (qps) or more than 40
million queries per day. This is a
substantial amount of traffic and
should easily suffice for even the
heaviest of Slashdottings. But if you
expect your application will need to
handle even higher qps, please

you.
I never used Amazon EC2 or RDS Service. I am trying to calculate my cost using http://calculator.s3.amazonaws.com/calc5.html
I searched a little but could locate answers to some basic things. Can you help me out with this:
What does DB Instance means? 1 Database = 1 Instance or 1 Connection = 1 Instance
How to calculate hours/month usage? It should depend on the transfer rates or processing time. Is there a way I can get rough Idea about it?
What if I already have my DB Ready and want to upload it directly (it would be few GBs) then how will it be calculated.
I am new to amazon EC2 and searched stackoverflow and serverfault before posting this question. Got some idea but not specific what I am looking for. Can someone help me out here?
In general, one database = one instance. You spin up instances, and do what you like with them. Definitely possible to have more connections to it.
Hours per month is just that. How many hours per month you have the instance active. If you plan to have the instance active 24/7, you may find more cost effective alternatives with other cloud providers. If you run it less often than that, you save money when it's not active. It's billed hourly to your account at the rate specified.
Upload data is counted at the standard transfer rates. A few GBs doesn't cost much, but you will be paying for the service starting the moment you spin up the instance.
