AWS Transit Gateway

Customers define VCNs according to specific workload IP address requirements, and can divide a VCN into smaller ranges using private or public subnets or assign multiple IP addresses to a single VCN. Extend existing on-premises networks and interconnects using virtual routers and gateways. Customers use peering gateways to connect different VCNs within a tenancy, or to connect securely to other tenancies. FastConnect allows customers to connect directly to their OCI virtual cloud network via dedicated, private, high-bandwidth connections. Then, based on the amount of data, customers simply chose an appropriate port speed and pay a consistent, low price each month. Other providers charge for the amount of data moved, which can be expensive and unpredictable.Prevent attacks on customer tenancies with isolated network virtualization. A foundational element of OCI’s security-first architecture, the design stops malware with a custom-designed SmartNIC to isolate and virtualize the network.

AWS PrivateLink provides private connectivity between VPCs, AWS services, and your on-premises networks, without exposing your traffic to the public internet. AWS PrivateLink makes it easy to connect services across different accounts and VPCs to significantly simplify your network architecture. Interface VPC endpoints, powered by AWS PrivateLink, connect you to services hosted by AWS Partners and supported solutions available in AWS Marketplace. By powering Gateway Load Balancer endpoints, AWS PrivateLink brings the same level of security and performance to your virtual network appliances or custom traffic inspection logic. You can connect services across different accounts and Amazon VPCs, with no need for firewall rules, path definitions, or route tables. There is no need to configure an Internet gateway, VPC peering connection, or manage VPC Classless Inter-Domain Routing (CIDRs).
