Summary
In this chapter, we explored the different concepts of connectivity to public clouds. Without connectivity, nothing will work – or at least nothing will be reachable. We have learned the major differences between the VPN concepts and the direct connectivity propositions of Azure, AWS, and GCP. An important lesson is that VPN connections are fine at lower bandwidths, but enterprises typically need more than that, and they should consider moving to direct connection solutions. To design a connectivity strategy for our business, we need to take some key parameters into account—the cost, internet access, security, and service levels.
From a technology perspective, we have studied concepts such as SDN and have also learned that you can extend an on-premises network to a public cloud with concepts such as VMware's NSX. Connectivity is king and therefore you also need to have a basic understanding of the various protocols that networks use to establish a connection...
