IBM Solutions for Hybrid Cloud Networking Configuration Version 1 Release1

This document describes the high-level networking architectures and required configuration for establishing the site-to-site Virtual Private Network (VPN) connectivity in the multicloud hybrid environment.

In today's environment, many organizations are using some form of cloud services, whether private, public, or hybrid cloud and storage infrastructure is an integral part of these deployments. A hybrid cloud is a combination of a private cloud that is combined with the use of public cloud services where one or several touch points exist between the environments.
Networking is the critical component of the hybrid cloud and site-to-site Virtual Private Network (VPN) IPSec tunnel is the widely used option for extending the on-premises environment across multiple public clouds. In this paper, we describe the high-level logical configurations between on-premises and various public cloud service providers, such as Amazon Web Services (AWS) and IBM® Cloud.
