+## Task Requirements 
 
 Your Grafana deployment will consist of the following resources: 
 
-- EC2 virtual machine: we will go with 1 t2.micro running Linux; 
-- For the EC2 we wil need a VPC and 1 Public IP; 
-- We will also use some S3 storage (**S3 Standard storage**) for Grafana database backups. We will need around 10GB of space, we will do a nigtly upload of DB backups and we will clean up the old backups when we will run out of planned storage space; 
-- All resources will be deployed to 'eu-central-1' region; 
-- We will use on-demand pricing witout any reservations;

+- All resources will be deployed to the *eu-central-1* region.
+- We will use on-demand pricing without any reservations. 
 
 To complete this task, you will need to perform the following steps: 
 
 1. Use [AWS pricing calculator](https://calculator.aws/) to calculate our cloud infra costs.
