The image shows a data migration from MongoDB to Oracle Cloud Infrastructure (OCI).

There is a customer data center with a MongoDB VM. MongoDB formatted JSON files are imported to an OCI Object Storage Bucket.

There is an OCI region that contains an availability domain, a fault domain, a virtual cloud network (VCN), a public subnet, a compute instance running Oracle NoSQL Database Migrator software, an internet gateway, and a service gateway (all within the VCN). Outside of the VCN is an Oracle Services Network with Oracle NoSQL Database Cloud Service, OCI Identity and Access Management, and OCI Object Storage.
