Some common network topologies for Hydric Cloud networking (public cloud interaction with private on-premise environments)

I faced several client that need a new hybrid network between current on-premisses DataCenter with new Cloud environment. I this list I just want to sumarize some common topologies commonly used , as follows:

• Mirrored topology. In this topology, the public cloud and private on-premise environments

mirror each other. This topology could be used to set up test or disaster recovery environments.

• Meshed topology. With this topology, all systems within all clouds and private networks

can communicate with each other.

• Gated egress topology. In this topology, on-premises service APIs are made available to

applications running in the cloud without exposing them to the public Internet.

• Gated ingress topology. With this topology, cloud service APIs are made available to

applications running on premises without exposing them to the public Internet.

• Gated egress and ingress topology. This topology combines gated egress and gated

ingress.

• Handover topology. In this topology, applications running on premises upload data

to a shared storage service, such as Cloud Storage, and then a service running in GCP

consumes and processes that data. This is commonly used with data warehousing and

analytic services.

Conclusion: Depending on the distribution of workloads, throughput and latency requirements, and topology, an architect may recommend one or more of three options supported previous chequed in the cloud selected to verify its support to the choosen topology.
