AWS CloudWatch Billing Alarm By Jayant Sharma You can monitor your estimated AWS charges using Amazon CloudWatch. When you enable the monitoring of estimated charges for your AWS account, the estimated charges are calculated and sent several times daily to CloudWatch as metric data. For beginners and students, Amazon Web Services has a  Free Tier , which is  very generous . However, as you move from free tier limits to general working, it’s good to have billing alerts set up that means you’ll get an email when your bill approaches a certain amount. Setting up billing alerts uses  CloudWatch .  The Billing metric data is stored in the US East (N. Virginia) region and represents worldwide charges What is actually done in this?

It provides cost-efficient, resizable capacity for an industry-standard relational database and manages common database administration tasks.  Administration processes like patching the database software, backing up databases and enabling  recovery  are managed automatically.

AWS Identity and Access Management (IAM)

By Jayant Sharma AWS Identity and Access Management (IAM) is a web service that helps you securely control access to AWS resources. You use IAM to control who is authenticated (signed in) and authorized (has permissions) to use resources. When you first create an AWS account, you begin with a single sign-in identity that has complete access to all AWS services and resources in the account. This identity is called the AWS account  root user  and is accessed by signing in with the email address and password that you used to create the account. It is strongly recommend by Amazon that you do not use the root user for your everyday tasks, even the administrative ones. Instead,  create your first IAM user . The root user credentials can be used only to perform only a few account and service management tasks. IAM helps keep track of  two-factor authentication  information and authorizations .  For example, a business owner can create “users” for as many employees as he/she has,
