RDS AWS Tutorial: Getting Started With Relational Database Service
Amazon RDS is the Relational Database Service offered by Amazon Web Services. It helps users easily set up or operate the relational database through the cloud. The reason why it is so popular is due to its cost-effectiveness since people don’t have to buy or invest in servers or subscribe to any additional software. In this article, you’ll find everything you need to know about starting with RDS AWS.
Components of RDS AWS
Now it’s time to discuss the various components of RDS AWS:
- The first one is the DB instances which can be considered the building blocks of RDS. Being a remote database in the cloud, it can contain multiple databases created by the users. Moreover, users can access it using the same tools or applications generally used in a standard database instance. The Amazon RDS API or the AWS Management Console can be used to create it.
- Next, we’ve got the various regions and the availability zones, which consist of data centres housing AWS‘s resources. Each region consists of availability zones built so that when one availability zone fails, it doesn’t affect the rest of them. Users can deploy their DB in multiple availability zones.
- The third components are the security groups, and they control the access to any DB instance. Amazon RDS mainly uses three security groups, the EC2 security group, the VPC and the DB security group.
- Up next, we have the DB parameter groups that contain the entire configuration values. It can be applied to one or more DB instances, especially of the same instance type. If it is not assigned, a default Parameter group is assigned default values.
- Lastly, there are the DB option groups that consist of tools to help users manage their databases.
Advantages Of Using RDS AWS
- Users can tweak parameters such as memory, storage, and CPU using RDS AWS. Users cannot tweak them individually otherwise.
- It manages servers and updates them automatically, alleviating the effort on the part of the user.
- It provides high availability by creating a secondary instance for a fall over.
- It helps reduce the overall overhead on a source DB by supporting read replicas.
- Users can integrate RDS AWS with IAM so that users can give customised access to those who are working on the database.
Launching a MySQL DB In Relational Database Service
- Go to the AWS Management Console and select the RDS service.
- From the list of available DBs, select the MySQL instance.
- Select the Dev/test option and click ‘Next’.
- Select the desired DB instance and determine whether you want multiple AZ enabled. You can also allocate the necessary space for your DB instance. After all, that’s done, you must set a username and password to secure your DB instance.
- In the next step, users can choose to go with the default settings or choose a VPC. We must also choose the version of the DB we want to use and then set up backup preferences.
- Users must set the maintenance window for the DB instances to be updated.
- After filling out all the necessary details, you will finally be ready to launch your DB instance.
Every day, millions of applications go online, and those numbers are reaching new heights with each passing year. Amazon RDS can do all the menial tasks such as the set-up, maintenance and operation, which would not have been possible a decade ago. We hope that by reading this tutorial, you have a fair idea about what an RDS AWS is and how to launch a MySQL DB in RDS.
