Adoption of public cloud IaaS platforms like AWS and Azure, and PaaS and SaaS solutions too, has been driven in part by the simplicity of consuming the services: connect securely over the public internet and start spinning up resources. But when it comes to communicating privately with those resources, there are challenges to address and choices to be made.
The simplest option is to use the internet—preferably an internet VPN—to connect to the enterprise’s virtual private clouds (VPC) or their equivalent from company data centers, branches, or other clouds.
However, using the internet can create problems for modern applications that depend on lots of network communications among different services and microservices. Or rather, the people using those applications can run into problems with performance, thanks to latency and packet loss.
