AWS RDS free tier: Is free usage reset every month? - amazon-web-services

I'm using AWS RDS by free tier.
I created a database in January, and created another databse in February.
Today morning, I got a message that I was charged 12 dollars for overusage.
I checked my AWS cost management, and found out that the cost for March so far is $0.
I know that the free tier gives me 750 hours.
But does it mean that I can use 750 hours every month?
If so, can I use one database for free every month because 750/24 = 31?
And did I get charged because I am activating two databases?
Thanks.

From the AWS documentation:
750 hours of Amazon RDS Single-AZ db.t2.micro Instance usage running MySQL, MariaDB, PostgreSQL, Oracle BYOL or SQL Server (running SQL Server Express Edition) – enough hours to run a DB Instance continuously each month
so if you run two instances, that will be a total of 1500 hours of usage, so you will be charged extra. But you can run one instance for free each month. Note that the RDS instance is part of the 12 months free tier in AWS. That means that this offer only holds for 12 months after creation of your AWS account.

I created an AWS account and use it for several years now. Now, I was experimenting with the RDS instance (free tier) and this started to change me.
So, I believe that the free tier is only free within 12 months of the AWS account creation.
CHECK DAILY THE AWS ACCOUNT, I had another mistake earlier that cost me $300 for that.

Can we create new EC2, RDS services under free tier when there are already existing other EC2, RDS instances?

On AWS, I already have an EC2 instance and PostgreSQL RDS which is working fine for more than 2 years. Now I added new EC2 instance and a new PostgreSQL RDS ( both are under free tier ). Later I found that the billing is added to this RDS even though I have selected free tier. Is this possible to create another EC2 and another RDS in the Free Tier when there is a EC2 and RDS running more than 2 years?
The AWS Free Tier is a billing discount provided by AWS. Some discounts are provided only for the first 12 months of an AWS Account, while some apply every month.
For Amazon EC2 instances, the AWS Free Tier provides the following discounts for the first 12 months:
750 hours per month of Linux, RHEL, or SLES t2.micro or t3.micro instance dependent on region
750 hours per month of Windows t2.micro or t3.micro instance dependent on region
For Amazon RDS databases, the AWS Free Tier provides the following discounts for the first 12 months:
750 Hours of Amazon RDS Single-AZ db.t2.micro, db.t3.micro, and db.t4g.micro Instances usage running MySQL, MariaDB, PostgreSQL databases each month (applicable DB engines)
20 GB of General Purpose (SSD) database storage
20 GB of storage for database backups and DB Snapshots
Both discounts are only provided for the first 12 months of your AWS Account. You might have selected services that are "free tier eligible" but they would not be free because your AWS Account is older than 12 months.

AWS EC2 Windows Server 2019 billing free tier

I'm just wondering about the free tier. I've created an EC2 instance with windows server 2019. When I selected it it said "free tier eligible". Does this mean it'll be free forever, will I be charged for something and how can I prevent any extra charges?
I believe you get 750 Hours per month for a single free tier instance during your first 12 months. Meaning you should just be able to keep it running for the first year of your membership.

AWS Lightsail MySql Database

I have taken a AWS Lightsail Unix Instance for one of my pilot project, I wanted to explore AWS ecosystem and thought this would be a easy playground to start with. The plan I opted was a USD 5 per month, which gives 1 GB Memory, 1 Core Processor, 40 GB SSD Disk and 2 TB Transfer.
After subscribing I created a LAMP instance and a Plesk Instance, assigned static IPs to both instances and setup connections from my PC to transfer files using PuTTY; also setup access to Plesk and phpMyAdmin to start work.
In the first month itself, I am seeing a huge bill of USD 985 for using AWS RDS, details in bill are as below:
Amazon Relational Database Service for MySQL Community Edition
$1.080 per RDS db.r4.xlarge Multi-AZ instance hour (or partial hour) running MySQL
My question is - When I created LAMP, does it create a AWS RDB service automatically, I have hardly used MySql for anything. It seems AWS Lightsail is throwing hidden charges without notifying customers about actuals.
No, creating a LAMP stack on Lightsail does not create an RDS instance on your behalf. With the LAMP stack on Lightsail, the MySQL database is installed on that instance alongside PHP and Apache - there is no charge beyond the $5.00 / month (in your case) as long as you don't go over the data transfer limit.
I can't say why you're getting charged for RDS, but it's not because you fired up Lightsail instances.
Thank you folks!
I tried to go through several docs AWS provides on pricing. There is no indication that AWS RDB services automatically starts on LAMP installation. I wanted to take second opinion before raising a complaint with them. I have opened a case, and they have confirmed to revert the charges, however there is no clarity how AWS RDS service has started. At present I have removed all DB snapshots and backups.

EC 2 free tier charges

I have an Amazon AWS account, with a few EC2 running instances (3) in different locations. I subscribed the 12 month trial. Suddenly, my billing dashboard started to stack up costs, updating every day.
The instances are virtual machines with windows server 2012, all configured under the free tier settings. I use them mainly form testing, with few downloads/uploads and streaming.
They Are charging for a few bucks for data transfer,and also a reasonable amount described as EC2.
I've read somewhere that one could create more than one EC2, and for what i supposed, the 750 hours limit is for each instance, But this probably is Wrong.
So, what can one do and not do, under the free Absolutely free tier limit ?
Based on the documentation you can run 750 hours of a Linux t2.micro or t1.micro instance plus 750 hours of a Windows t2.micro or t1.micro instance each month for the first 12 months under the free tier. So in your case you have exceeded the free tier limitations, by starting 3 Windows Server 2012 instances and keep them running more than 2/3 of the month.
Since AWS Free Tier involves 750hrs of Free Time per month, you could ideally start 750 EC2 instances, 1 hour/per month.

Free Amazon AWS/RDS Instance

I have hosted a server app on AWS and RDS for relational DB. Though I opted for free account, RDS is being charged at $0.0025 per hour amounting to $18 a month.
I read some documentation but still not able to figure this out. Is this the way it is or is there a way to get free RDS account for testing purpose?
Thanks

I've just started setting this up and I realized quickly that it was allowing me to make selections that couldn't possibly be free. When setting up your free teir instance, look on the left hand side of the screen for
Your current selection is eligible for the free tier.
Once you select something like "Multi-AZ Deployment" or use any DB Instance Class other than "db.t2.micro" it will slyly change the left column display:
The following selections disqualify the instance from being eligible for the free tier:
Multi-AZ Deployment
Just be careful in your selections and usage to maintain the free teir.
What type of database are you running ? The free tier only applies to SQL Server Micro DB Instance:
750 hours of Amazon RDS for SQL Server Micro DB Instance usage
(running SQL Server Express Edition in a single Availability Zone)
See http://aws.amazon.com/free/
There is also a 60 day free trial for MySQL and Oracle:
See http://aws.amazon.com/rds/free-trial/
Your simplest option is to install the database on your instance.
Alternatively you could look at using a hosted MySQL service provided like http://xeround.com/, or http://www.cleardb.com/, both have limited but free options.
As of October 1st 2012, AWS free usage tier now includes Amazon RDS.
The free tier applies to Single-AZ deployments of MySQL, Oracle “Bring-Your-Own-License (BYOL)” licensing model and SQL Server Express Edition.
See this link from Amazon for more details:
https://aws.amazon.com/about-aws/whats-new/2012/10/01/amazon-rds-aws-free-tier/
you should use t1.micro. It is at the bottom of the options.
The important thing is not to choose RDS Aurora.
If you choose MySql or Postgres, the webpage will show template Free Tier.
When select it, all default configs will be good for free tier.

I recently provisioned an AWS RDS instance. I thought I was within my free tier limit and I kept being charged for "Amazon Relational Database Service Provisioned Storage". It was always a few cents.
I had taken between 15 and 20 GB of storage when I set it up.
I contacted support and they told me that, in order to be within the RDS free tier, I have to take no more than 9Gb storage when provisioning the instance. But after the backup is made, it will use up an additional 9Gb, so the total storage should be no more than 20Gb.
So now, when I provisioned a new instance of 9 GB, I am within the limits of the free tier.
Also always check if in the region of choice they have free tier resources.
