Build Cloud Connectivity

Cloud Service Providers (CSPs) present a wide range of networking constructs and tools to facilitate the creation of Layer 3 underlay connectivity across VPCs/VNets. However, constructing a global cloud underlay network using these constructs remains a complex and challenging task due to the following reasons:

  • Diverse Networking Constructs: Each CSP has its own unique set of networking constructs, making it necessary to have a comprehensive understanding of each construct and how they interact with one another when building a global cloud underlay network.
  • Manual Configuration: Cloud administrators are required to access each CSP’s cloud console and navigate through multiple steps and tabs to attach a single VPC or VNet. This time-consuming and repetitive process must be repeated for each region and VPC/VNet that needs to be connected. Similarly, removing a VPC/VNet from the global underlay network involves following the same multi-step process.


Alternatively, organizations can bring traditional network architectures onto cloud providers as hub & spoke overlay networks. However, the dissociation of the network overlay from the diversity of the cloud platform surface area inhibits organizations from fully leveraging the agility promise of cloud compute and services.


Abstraction of cloud provider specifics/nuances coupled with orchestration of the many resources involved in securely linking together multi-platform, distributed applications.

Key benefits of Prosimo’s Visual Transit feature:

Introducing Cloud Transit Building

1. Create Network Transit



With Cloud Account on-boarding and the deployment of regional Network Edges complete (see: Discover Networks), Prosimo enables simple, click-connect implementation of connectivity across networks, regions, and clouds.

Operators select dynamically discovered networks before orchestrating the deployment of transit across cloud route tables, transit gateways, NAT Gateways, Security Groups, and more.


See the steps to build transit in this click-through demo:

2. Monitor Orchestration



Prosimo orchestrates the configuration of all cloud-native network resources between source and destination networks, ensuring secure connectivity across networks, regions and cloud providers.

During the cloud-native resource creation process, existing resources are configured, and missing elements are created and interconnected as required.

 The cloud region deployed Prosimo Edge’s provide an mTLS authenticated cloud mesh to securely interconnect regions and apply intelligent “Path Selection” as needed to ensure resilience and performance.
