When all of your business is driven by end users coming to use your applications over the Internet, the network is arguably the most critical part of the infrastructure. That is why search engine and ad serving giant #Google, which has expanded out to media serving, hosted enterprise applications, and cloud computing, has put a tremendous amount of investment into creating its own network stack. But running a fast, efficient, #hyperscale network for internal datacenters is not sufficient for a good user experience, and that is why #Google has created a #softwaredefinednetworking stack to do routing over the public Internet, called #Espresso. Google believes that Espresso not only has the potential to change the way routing is done on the Internet for its users, but also has the potential to shape the way routing gets done on the Internet at large. This could be one of those defining moments where Google shows the way and the world follows. Amin Vahdat, Google Fellow and technical lead for networking at the company, recently walked us through Google’s implementation of Espresso routing on the public Internet, the fourth pillar of networking that the company has divulged thus far. Vahdat also talked about how networking technology, in terms of both hardware and software, are starting to see the pace of innovation pick up again after a tough slog there in the past decade, something we have mused upon recently. All of the hypercalers have spent more than a decade building their own networks, including homemade switches and routers and a complete software stack that makes them malleable and scalable in the same manner as the compute and storage infrastructure that gives them a huge advantage in the IT sector and among application providers.
