Mahendra Ramsinghani is the founder of Secure Octane, a Silicon Valley-based cybersecurity seed fund.

The Linux Foundation recently announced the launch of the Reactive Foundation. Its founding members are Alibaba, Lightbend, Pivotal and Netifi. So what exactly is this Reactive Kool-Aid, and why are all these companies guzzling it down so fast?

Premise - Microservices - World - Applications - Compute

If you buy the premise that developers live in a cloud-native microservices world, then you also understand that most applications are distributed and elastic. The compute is spread across clusters, as is all the data. It could be a few users, or a spike of thousands. Systems need to be architected to handle these spikes. Yet the dark secret of microservices is complexity — the management of resources, costs, performance and latency remain a challenge.

If we break down any application into hundreds of moving parts (such as containers and microservices), then we better have an elegant way to manage those moving parts. These services need to talk to each other, exchange data and ensure that overall performance is reliable, at all times. Easier said than done.

Problem - Cloud

The “big unsolved problem of the cloud”

According to Daniel Berg, Distinguished Engineer at IBM Cloud, “The network is the unsolved problem of the cloud…. We need the network to be a first-class citizen of a cloud system.” Why does the network remain a problem? Is it because we fall back on our old ways, when we need to rethink the new? We have designed the car with the big clunky wheels of a horse buggy. Conceptually, it sounds fine — but it can be a pretty rough ride.

Cake - Network - Protocols - Layer - Transportation

In the layered cake of network protocols, we have the middle layer of transportation (Transmission Control Protocol / Internet Protocol or TCP/IP), and right at the top, we have the application layer. We use a protocol called hypertext...
