What provides network connectivity between resources deployed in two different IBM Cloud VPCs?
IBM Cloud Transit Gateway provides network connectivity between different IBM Cloud Virtual Private Clouds (VPCs). It allows for secure, scalable, and efficient communication between resources deployed in separate VPCs, whether they are within the same region or across different regions.
How Transit Gateway Works: It acts as a central hub that facilitates the routing of traffic between multiple VPCs without the need to configure individual VPC peering connections. This simplifies network management, improves scalability, and enhances security by maintaining a single point of control.
Benefits of Transit Gateway: This service supports both private and public connectivity options and allows for routing policies that can be customized according to business needs. It also provides seamless integration with other IBM Cloud services and third-party networks.
Comparison of Other Options:
Domain Name System (A): Not used for network connectivity between VPCs.
Direct Link (B): Used for dedicated, high-speed connections from on-premises to IBM Cloud but not between VPCs.
Power Edge Router (D): Not an IBM Cloud service for inter-VPC connectivity.
