- Data Migration: What Is It?
- Many databases and data kinds
- Naming Conventions for data migration technologies used in AWS, GCP, AZURE, and OCC
- Data migration tools and strategies from on-premises to cloud services like AWS, GCP, and OCC
- Advantages of both on-premises and cloud databases
- Conclusion
The process of moving data from one system to another, such as from an old database to a new one or from an on-premises system to a cloud-based system, is referred to as Data Migration.
Different database management systems (DBMS) including MySQL, Oracle, Postgres, DB2 and SQL Server are used to manage various sorts of data and databases, including structured data (like that found in a relational database) and unstructured data (such text and images).
Data transfer technologies like the AWS Database Migration Service, GCP Database Migration Service, and OCC Data Transfer Service are all offered by AWS, GCP, and OCC (Oracle Cloud Infrastructure). Data migration between several databases and/or cloud platforms is possible using these technologies.
AWS, GCP, and OCC all offer a variety of data migration tools to help users move data between their different services and platforms.
AWS:
- AWS Data Migration Service (DMS): A fully managed service that makes it easy to migrate data to and from various databases, data warehouses, and data lakes.
- AWS Schema Conversion Tool (SCT): A tool that helps convert database schema and stored procedures to be compatible with the target database engine.
- AWS Database Migration Service (DMS) and AWS SCT can be used together to migrate data and schema both.
GCP:
- Google Cloud Storage Transfer Service: A fully managed service that allows you to transfer large data sets from on-premises storage to Cloud Storage.
- Google Cloud Storage Nearline: A storage service that stores data at a lower cost but with a slightly longer retrieval time.
- Google Cloud SQL: A fully-managed relational database service that makes it easy to set up, maintain, manage, and administer your relational databases on Google Cloud.
- Cloud Dataflow
- Cloud Dataproc
- Cloud SQL
- Cloud Spanner
Azure:
- Azure Database Migration Service (DMS)
- Azure Data Factory
- Azure Data Lake Storage Gen1
- Azure Data Lake Storage Gen2
- Azure Databricks
- Azure Stream Analytics
OCC:
- Oracle Cloud Infrastructure Data Transfer Appliance: A physical appliance that allows you to transfer large data sets from your on-premises data center to Oracle Cloud.
- Oracle Cloud Infrastructure FastConnect: A service that provides a dedicated, private connection between your on-premises data center and Oracle Cloud.
- Oracle Cloud Infrastructure File Transfer: A service that allows you to transfer files between your on-premises data center and Oracle Cloud.

The process typically involves several steps:
- Identification of the data that needs to be migrated
- Planning for the migration, including assessing the data's size and complexity, determining the necessary resources, and developing a migration schedule
- Backup of the existing data
- Testing the migration process
- Execution of the migration
- Verification of the migrated data
- Switchover to the new cloud-based system
- Post-migration monitoring and maintenance
- It's important to note that the specifics of data migration to the cloud can vary depending on the specific cloud service provider and the type of data being migrated.
When migrating data from an on-premise system to a cloud-based system such as AWS, GCP, or OCC, the process typically involves several steps, such as assessing the current data and design, planning the migration, and testing the migrated data.
Cloud migration tools and strategies can include various options, such as using pre-built templates and scripts, leveraging cloud-native services, and utilizing third-party migration tools.
The benefits of on-prem and cloud databases can vary, with on-premise databases providing more control and customization while cloud-based databases often offer scalability and cost savings.
In conclusion, data migration is the process of transferring data from one system to another, with different types of data and databases, and various migration tools available in AWS, GCP, and OCC. Cloud migration tools and strategies can be used to migrate data from on-premise systems to cloud-based systems and the benefits and drawbacks of both on-premise and cloud databases.
