Amazon Relational Database \/ Amazon RDS<\/strong> is a managed relational database service provided by AWS<\/a>, aws\u00a0 will take care of\u00a0 hardware,\u00a0 \u00a0management part , taking backups etc. it makes it easier to setup , operate and scale relational databases in the aws cloud, Some of its important features include Dashboard, Databases, Performance Insights and Snapshots for backup and disaster recovery , lower administrative burden\u00a0 , scalability , performance, advanced security , cost-effectiveness, higher availability.<\/p>\n

The different Database engines that are supported by RDS are MySQL, SQL Server, PostgreSQL, Oracle, MariaDB, Amazon Aurora, Amazon RDS Custom.<\/p>\n

Why Choose RDS over EC2\u00a0 or on-premises setup<\/strong><\/h3>\n

Elastic\u00a0 Compute Cloud<\/a> (ec2) provides scalable compute capacity in the AWS cloud<\/strong><\/a> , amazon ec2 eliminates your need to invest in the hardware upfront so that you can develop and deploy applications faster\u00a0 and for a relational database in an\u00a0 \u00a0on-premises server\u00a0 you need to take\u00a0 full responsibility for the server, operating\u00a0 system and database software for this you need to have\u00a0 dedicated teams for each task\u00a0 and for a database on an amazon ec2 instance\u00a0 amazon manages the layers below the operating system\u00a0 \u00a0in this way amazon ec2 eliminates some of the burden of managing an on-premises database server , so it is a better solution than on -premises management, then why we need RDS ?<\/p>\n

Amazon Relational Database Service (Amazon RDS) is a web service that makes it easy to set up,\u00a0 scale\u00a0 and operate\u00a0 relational database in the cloud. It provides cost efficient, scalable\u00a0 capacity for an industry-standard relational database and manages common database administration tasks , it <\/span><\/span><\/span>frees you to focus on your application and your users,\u00a0 AWS itself suggest customers use RDS over ec2 for relational databases, below table gives you clear understanding why you should choose RDS over setting up databases on ec2 instances ,\u00a0 Amazon RDS will manage every thing expect the application optimization.<\/p>\n<\/div>\n

\"\"<\/div>\n
<\/div>\n
Now let’s understand some of the RDS concepts<\/div>\n
DB instance<\/strong> is an isolated database is an isolated environment in the AWS cloud , its the basic building block of amazon RDS , its the database server on which the database software runs.<\/div>\n<\/div>\n<\/div>\n<\/div>\n
<\/div>\n
Database Instance class\u00a0<\/strong> determines the computing and memory capacity of a DB instance , a\u00a0 DB instance class consists of both the DB instance type and the size , each instance type will have\u00a0 different compute , memory, and storage capacities.<\/div>\n
\n
\n
\n
<\/div>\n
DB engines\u00a0<\/strong> is the specific relational database that runs on your DB instance as mentioned Amazon RDS supports various engines like MySQL, MariaDB , PostgreSQL…<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Database Backup Retention Period <\/strong>is the \u00a0number of days for which automated backups are retained, by setting this parameter to a positive number you can enable backups\u00a0 backups, set it to 0 (zero) if you want to disable automated backups.<\/p>\n

Database Subnet Group <\/strong>allows you to specify a particular VPC when you create DB instance. If you use the\u00a0 AWS web console, you can choose the VPC and subnets you want to use, each DB subnet group must have at least one subnet in at least two Availability Zones in the AWS Region \u00a0to support Multi Availability Zone\u00a0 DB instance deployments.<\/p>\n

Launch RDS Instance using Cloud Formation<\/h3>\n
On you AWS web console open CloudFormation and click on Create Stack , In step-1 select Template is ready\u00a0\u00a0<\/strong>for prerequisite and choose template source<\/p>\n
\"\"<\/p>\n
In step-2 give a name to your stack\u00a0 and\u00a0 you can also change the default parameter\u00a0 values here .<\/p>\n
\"\"<\/p>\n
In step-3 configure your stack options like Roll back options, permissions, tags\u00a0 and in step-4\u00a0 review your stack configuration and click on create to create the resources , you will be redirected to events page where you can see the progress of resources creation.<\/p>\n
\"\"<\/p>\n
Connecting to Amazon RDS from a EC2 Instance<\/h3>\n
Once the resource is created successfully, go to RDS on your AWS console\u00a0 , and click on the Database Identifier name\u00a0 that you want to connect to, connecting to database on RDS is nothing new from\u00a0 \u00a0accessing a remote database server\u00a0 it only varies based on the database engine you use.<\/p>\n
\"\"<\/p>\n
Copy the endpoint from Connectivity and Security\u00a0 \u00a0and store it somewhere.<\/p>\n
\"\"<\/p>\n
on you ec2 instance install MySQL client\u00a0 , you can following command\u00a0 \u00a0on a Linux server.<\/p>\n
sudo yum install mysql<\/pre>\n
\"\"<\/p>\n
use the following command to connect to the database, and enter the database password when it prompts for<\/p>\n
mysql -h <database endpoint> -u <username> -p<\/pre>\n
