I have an app that starts and stops an RDS instance on-demand. I understand how AWS charges for a stopped RDS instance.
Does AWS charge for startup/shutdown compute time?
The pricing documentation for RDS indicates:
Pricing is ... from the time a DB instance
is launched until it is stopped or deleted.
For RDS, more specifically:
RDS is billed in one-second increments for database instances and
attached storage. Pricing is still listed on a per-hour basis, but
bills are now calculated down to the second and show usage in decimal
form. There is a 10 minute minimum charge when an instance is created,
restored or started.
FYI, for regular EC2 instances:
Each time you start a stopped instance we charge a minimum of one
minute for usage. After one minute, we charge only for the seconds you
use.
The most cost efficient solution would be to use aurora serverless. This way you dont have to start and stop the instance.
https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-serverless.html
When you use Aurora Serverless, you pay for only the database resources that you consume, on a per-second basis.

I just followed a tutorial to create an RDS database. Since the time of creating my will I be charged every hour for which my database instance is active or will I be charged for everytime I make a query to the database?.
The simple answer is that you're charged for every hour your RDS instance is running, and (broadly) not how much you actually use it. There may be some small charges for large volumes of queries, but keeping the instance running is the main cost.
However if you're a new customer you can have a small RDS instance free for a year. Look for 'free-tier eligible' on the management console.
AWS has detailed pricing category for different DB which should be clear enough. Taking mysql "On-Demand DB Instances" as an example, it charges based on the type and duration, however for RDS T3 DB instances which uses unlimited mode it may involve extra fees if your average CPU usage exceed baseline.
It seems that my EC2 usage limit is being reached rather quickly. I have deleted all of my EC2 instances and most of my S3 buckets, and none of my EC2 instances even exist in the terminated state. Are there any other services other than EC2 that use the EBS storage? Thanks in advance.
Amazon EBS is only used by Amazon EC2 instances. (Well, it is also used by Amazon RDS, but it shows up as an RDS charge, not EBS.)
We are currently about a third of the way through the month, so you'd want to be around 30% of usage.
The Amazon EBS snapshot usage is ahead of that (58%). If this worries you, then you can delete snapshots under the Snapshots section in the EC2 console. Amazon Machines Images (AMIs) also use EBS snapshots, so check the Images section too.
The amounts are "growing" because they are based on a month of usage. So, 1GB for 1 day is ~ 3% of the month's total.
However, there is little need to panic — EBS Snapshots are charged at 5c/GB/month, so at the current rate of usage you might be charged 10c.
There can be another possibility where you run an instance with EBS volumes 'not deleted' even after the termination of instance, it can accrue storage charges also. So delete those ones also in the 'Volumes' section of EC2 instance if its still unused.
I'm getting ready to launch a mobile app that I have hosted on AWS with an EC2 instance. ($0.0464 per On Demand Linux t2.medium Instance Hour).
This past month I was charged $112 for the EC2 usage, but only had a handful of internal users testing the private version of the app. It's a fairly simple app, not anything that should require a lot of computing power.
So what I'm wondering is if 10 users and dev team costs $112/mo, what happens if I get 1,000 users, or 10k users? Would the cost increase 100x, 1000x? I can't imagine getting auto-billed for $112,000 for a month of service with a small user base like 10k users.
Thanks for any help and guidance, I don't know much about AWS.
Here are the details of my billing for last month:
The billing page shows 2219 hours of t2.medium during this billing month.
That is the equivalent of 92 days. So, it might be 3 instances running for a full month.
Amazon EC2 is charged when the instance is in the Running state. If you are not using an instance, you can Stop the instance. The attached disks (EBS) will still be charged, but there will be no charge for the instance itself.
The charge is not based on the number of users, nor how 'busy' the instance is. It is simply charged when the instance is 'running'. This is because computer resources are exclusively assigned to instances (CPU, RAM) that nobody else can use.
Bottom line: Stop instances that you don't need. Use the smallest instance type for your use-case to reduce costs.
If you were not aware of the charges involved, you can contact AWS Customer Service and request a refund.
FYI, the T2 and T3 family are great for workloads that occasionally 'burst' but then have low-usage periods, but they are not great for sustained workloads. See: Burstable performance instances - Amazon Elastic Compute Cloud
I lunched a reserved instance for RDS yesterday. I waited for the billing to be updated till today morning (it takes normally 6 hours to a day). Now when I go to the Billing the reserved instance and on-demand instance, both are active and being charged. I was hoping once I created the reserved instance of same instance type, AZ, Tenancy the reserved instance would apply to the on-demand instance.
My on-demand aurora mysql instance look like this:

My Billing overview:
======== Edit
Apparently, It takes 24 hours to takes RI to take effect so that on demand instance can use it. There was nothing wrong with what I've done... just needed some time.
Is there any changes for "traffic" when using basic version of EC2 instance, by basic I mean:
750 hours per month of Linux, RHEL, or SLES t2.micro instance usage
Traffic: If we setup a server and there are some hits on my server then is there any charge for this setup. I am not using ELB, just EC2 instance with a server on it.
The full pricing for On-Demand Amazon EC2 instances can be found at: https://aws.amazon.com/ec2/pricing/on-demand/
The AWS Free Usage Tier gives 750 hours per month of a t2.micro instance. This means you could run one instance for a full month, or two instances for half a month. Simply stop the instance(s) to stop the charges.
You can have this free usage tier for a Linux AND a Windows instance.
However, please note that there are additional charges that also apply:
Data Transfer: This is charged for data leaving the AWS Region going to the Internet. The free usage tier includes "15 GB of bandwidth out aggregated across all AWS services" in the first 12 months. The EC2 pricing page also says that the first 1 GB/month is free, but I'm not sure if they overlap.
EBS Volume storage: Elastic Block Store (EBS) runs the disks attached to your instance. The free usage tier includes "30 GB of Amazon Elastic Block Storage in any combination of General Purpose (SSD) or Magnetic, plus 2 million I/Os (with EBS Magnetic) and 1 GB of snapshot storage", so you will be charged if your disk storage exceeds this (which is likely if you run both a Windows and a Linux instance). This storage charge continues to apply when an instance is Stopped, but not when an instance is Terminated.
Bottom line: Stop or turn off things when you don't need them. You can also activate a billing alert to warn you when you have been charged some actual money.
Yes, there are varying charges for traffic into and out of your EC2 instance.
in very rough numbers, if you budgeted $0.01 per GB of traffic, you would come in under that, but the complete breakdown is here:
