Google Cloud Platform (GCP) provides several tools and services to assist in migrating workloads and applications to its cloud environment. These tools can help simplify the migration process and ensure a smooth transition from on-premises or other cloud platforms to GCP. Here are some commonly used migration tools offered by GCP:

1. Cloud Migration for Compute Engine: This tool helps migrate virtual machines from various sources, such as on-premises data centres or other cloud providers, to Compute Engine instances on GCP. It simplifies the process of replicating VMs, creating images, and launching instances in GCP.

2. Database Migration Service: This service enables seamless migration of databases from on-premises or other cloud platforms to GCP. It supports popular database engines like MySQL, PostgreSQL, and SQL Server, providing a managed and automated process for data migration.

3. Transfer Service: The Transfer Service allows you to transfer large amounts of data to GCP quickly and securely. It supports transferring data from on-premises systems or other cloud providers via the Internet or by shipping physical storage devices to Google for data ingestion.

4. Apigee API Platform: Apigee is an API management platform that helps in modernizing and migrating existing APIs to GCP. It provides tools for designing, building, securing, and analyzing APIs, facilitating the migration of legacy API infrastructure.

5. Velostrata: Velostrata is a cloud migration tool acquired by Google, specifically designed for large-scale cloud migrations. It enables the migration of virtual machines to GCP while minimizing downtime and offering features like dynamic instance resizing and automatic network configuration.

6. Anthos: Anthos is a hybrid and multi-cloud platform that simplifies application migration and modernization. It allows you to run applications consistently across different environments, including GCP, on-premises, and other cloud platforms.

These are just a few examples of the migration tools offered by GCP. Depending on your specific needs and requirements, you may find other tools and services within the GCP ecosystem that can further assist you in migrating your workloads and applications to Google Cloud Platform.
