I'm running a db.m4.large RDS instance. It is advertised everywhere as having 8GB of memory. Though on the monitoring screen it only shows ~1.2GB.
Am I misunderstanding something here?
AWS RDS scales that memory bar not by the total memory capacity but by the percentage of the threshold it is taking up. This would mean that somewhere in your AWS Console a auto-scaling or auto-alert threshold on RDS memory has been set at ~1.25 GiB.
I know this because, for example, I have an RDS instance with 2GiB memory but the memory bar shows what appears to be ~4GiB because that is the default threshold in my auto-scaling groups.

I created a free account since more time to test aws services. Last week I started 2 ec2 instances and I created an EKS cluster. After one day I found 26€ as billing.
I removed all EC2 instances, the cluster EKS, the users that I created them, the users-group, I deleted every thing from the account. But the billing is still increasing without any running service. Now I have 40€. I created an incident to aws support but I don't now when they will answer me.
Do you have an idea please ? thanks
You can see exactly what you are being billed for by visiting the billing console. If you look at the bills page it will default to the current month.

Can I run a EC2, t2.micro instance & a RDS db.t2.micro instance, parallel & continuously a whole month ?
Or is it I can only run one of them ?
I know both of them have 750 hours of up time available in the free tier. But I'm bit confused whether it is (EC2 OR RDS) or (EC2 & RDS) in the free tier.
Yes, you are able to run these parallel.
See free tier terms for more information.

I stumbled upon this term reading AWS documenation, some instances are recommended for building fleets but I have no clue what that is. What is a front-end fleet?
A fleet of ec2 instances means a group of instances engaged in the same activity within a group such as autoscaling, load balancing, batch processing, clustering and etc.
A fron-tend fleet generally referred to a set of EC2 instancers first act upon a load. For example set of web server instancers directly getting web traffic behind a load balancer.

What is the best way to cut costs on AWS?
AWS, EC2 and RDS
There's not a lot of info given for your needs, but: AWS pricing is based on usage. Use less powerful instances for less time to save costs.
Glacier over S3 for long term storage.
Autoscaling, run as minimal as possible.
Smaller cache servers to lower the amount of application servers needed.
Read/write DB splitting so you can have smaller databases.
Less metrics, etc.
Used timed autoscaling to shut off non-essential boxes "after hours". Like dev boxes.

I created my own intance and made AMI from it. Then, I deleted the old instance and created the new one with the AMI.
Here's the problem. I have been tracking my billing. It hasn't been eligible to Free Tier. This December, I spent almost $11 for EC2. I've used only EC2, I checked others services already.
Note that my first created instance is Micro instance with Ubuntu 13.
Do you have any ideas what does it come from?
Make sure you use a t1.micro instance otherwise you are not eligible for the free tier. Also make sure your EBS volume is < 30GB otherwise you will be charged.
