In this step, we will move the data from the on-premises database to the AWS environment. There are several ways to transfer data, and the method chosen will depend on the size of the database, the available bandwidth, and the level of complexity involved.
One common method is to use the AWS Database Migration Service (DMS). DMS can migrate data from most widely used commercial and open-source databases such as Oracle, PostgreSQL, Microsoft SQL Server, Amazon Redshift, Amazon Aurora, MariaDB, and MySQL. DMS can also handle schema and data transformations during the migration process.
Another option is to use the AWS Snowball Edge device. This device is a rugged, portable appliance that can store up to 100 TB of data and can be used to transfer large amounts of data to and from AWS. Once the data is transferred to the Snowball Edge, it can be shipped to an AWS data center for import into the target database.
Data Validation
After the data transfer is complete, it’s important to validate the data to ensure that it was transferred correctly and accurately. This step involves comparing the data in the source database with the data in the target database to ensure that they match.
One way to validate the data is to use the AWS Database Migration Service (DMS) task logs. These logs contain information about the migration process, including any errors or warnings that occurred during the transfer. By reviewing the task logs, you can ensure that the data was transferred correctly and accurately.
Another option is to use a third-party validation tool. These tools can compare the data in the source and target databases and identify any discrepancies. Some popular validation tools include Redgate SQL Compare and Idera SQL Comparison Toolset.
In conclusion, executing the migration involves two main steps: data transfer and data validation. By following best practices and using the appropriate tools, you can ensure a smooth and successful migration to AWS.
Post-Migration Activities
After migrating on-premises data to AWS, there are a few post-migration activities that need to be performed to ensure the smooth running of the migrated applications. In this section, I will discuss two critical post-migration activities: monitoring and management, and optimizing costs.

Troubleshooting Common Migration Issues
During the migration process, it is common to encounter issues that may affect the performance of the migration. In this section, I will discuss some of the most common issues that you may encounter and provide some troubleshooting tips to help you resolve them.
Insufficient Resources
One of the most common reasons for a migration task running slowly is that there are inadequate resources allocated to the AWS DMS replication instance. To make sure that your migration task runs smoothly, you need to allocate sufficient resources to the replication instance. This includes CPU, memory, and network bandwidth. You can check the resource utilization of the replication instance by using the CloudWatch metrics. If you find that the replication instance is running out of resources, you can increase the instance size or add more instances to the task.
Network Connectivity Issues
Another common issue that you may encounter during the migration process is network connectivity issues. This can occur if there is a firewall or other network security device that is blocking the traffic between the source and target database. To troubleshoot network connectivity issues, you can use the AWS DMS diagnostic support AMI. This AMI provides a set of tools that you can use to diagnose and troubleshoot network connectivity issues.
Large Object Migration
AWS DMS migrates large objects (LOBs) differently than other data types. During the full load and change data capture (CDC) phase, AWS DMS migrates LOBs in chunks rather than as a single object. This can cause poor performance during the migration process. To optimize the migration of LOBs, you can increase the LOB chunk size. You can also use the AWS DMS task settings to exclude LOBs from the migration.
By following these troubleshooting tips, you can ensure that your migration task runs smoothly and completes on time.
Conclusion and Next Steps
In conclusion, migrating on-premises data to AWS involves several steps, including migrating the data to Amazon S3 using AWS DataSync, configuring AWS Glue Catalog with a Glue crawler, visualizing data with a Glue Catalog in AWS Quicksight, and automating new data visualization with AWS Lambda and Amazon S3 events. Throughout this process, it is important to keep in mind the benefits of migrating to AWS, such as heightened security, quick deployment, scalability, lower energy costs, high availability, and disaster recovery.
