How to Set Up AWS DMS Service to Migrate Data from On-Premises to AWS with Example and Setup Guide
AWS Database Migration Service (DMS) is a fully managed service that makes it easy to migrate databases to AWS quickly, securely, and seamlessly. DMS enables you to migrate your data from on-premises infrastructure to AWS with minimal downtime and disruption.
In this blog post, I will guide you through the setup of AWS DMS service to migrate data from on-premises to AWS with an example and setup guide.
Example Scenario:
Let’s assume that you have a MySQL database running on an on-premises server, and you want to migrate it to an Amazon Relational Database Service (RDS) instance in AWS.
Setup Guide:
- Set up an Amazon RDS instance: Before you can start migrating data, you need to create an Amazon RDS instance to serve as the target for your database migration. Follow these steps to create an Amazon RDS instance:
a. Log in to your AWS Management Console.
b. Navigate to the Amazon RDS console.
c. Click on the “Create Database” button.
d. Select the database engine you want to use (in this case, MySQL).
e. Choose the instance type, storage, and other settings for your RDS instance.
f. Specify the username and password for your database.
2. Create a replication instance: The replication instance is a server that AWS DMS uses to migrate data from the source database to the target database. Follow these steps to create a replication instance:
a. Navigate to the AWS DMS console.
b. Click on the “Create replication instance” button.
c. Specify the replication instances settings, such as instance type, VPC, and security group.
d. Provide the username and password for your replication instance.
3. Create a source endpoint: The source endpoint is the on-premises database you want to migrate to AWS. Follow these steps to create a source endpoint:
a. Navigate to the AWS DMS console.
b. Click on the “Create endpoint” button.
c. Select the database engine (in this case, MySQL) and provide the necessary connection details, such as hostname, port number, username, and password.
d. Test the connection to ensure that AWS DMS can connect to your on-premises database.
4. Create a target endpoint: The target endpoint is the Amazon RDS instance you created earlier. Follow these steps to create a target endpoint:
a. Navigate to the AWS DMS console.
b. Click on the “Create endpoint” button.
c. Select the Amazon RDS instance as the target database and provide the necessary connection details, such as the endpoint address, port number, username, and password.
d. Test the connection to ensure that AWS DMS can connect to your Amazon RDS instance.
5. Create a replication task: The replication task is the process of migrating data from the on-premises database to the Amazon RDS instance. Follow these steps to create a replication task:
a. Navigate to the AWS DMS console.
b. Click on the “Create task” button.
c. Specify the replication task settings, such as the source and target endpoints, the replication instance, and the migration type.
d. Choose the database objects you want to migrate.
e. Start the replication task.
6. Monitor the migration progress: You can monitor the progress of the migration by navigating to the AWS DMS console and viewing the replication task details. AWS DMS provides real-time metrics that you can use to track the progress of the migration.
Conclusion:
AWS Database Migration Service (DMS) is a powerful tool that makes it easy to migrate databases to AWS quickly and securely. In this blog post, I have guided you through the setup of AWS DMS service to migrate data from on-premises to AWS with an example.
