Why Amazonâs new Lambda cloud service is a huge deal for devs â and the cloud market

At Amazon Web Servicesâ big annual user conference in Las Vegas this week, executives from the market-leading public cloud made all the moves that spectators were expecting: a few new products, a new generation of server chips for running applications, some customer wins, and greater support for Docker. But one announcement has elicited a rare mix of excitement, curiosity, and even outright confusion from analysts.
That would be Amazonâs reveal of Lambda, which Amazon chief technology officer Werner Vogels simply described as âan event-driven computing service for dynamic applications.â It might sound like yet another service in the Amazon cloudâs ever-expanding portfolio. But really, itâs a tool to implement rules that carry out functions using Amazonâs manifold complex features, without requiring extensive configuration and maintenance.
And that means it could be a major step forward for software development in the cloud.
âThis is revolutionary, or potentially revolutionary,â David Floyer, cofounder and chief technology officer of technology analysis firm Wikibon, told VentureBeat in an interview.
Floyer expects Lambda to give lots of developers the ability to write applications that ordinarily would be very difficult to craft. It could be useful for applications involving the Internet of things, whereby data from connected devices could set off triggers within applications.
And Floyer sees Lambda as a major achievement from a competitive standpoint. He certainly didnât see it coming.
âThere is somebody kicking somebody extremely hard inside of Google and inside of Microsoft,â he said.

At the same time, some people see it as a reinvention of a cloud model that has existed in the cloud world for years now.
On his blog High Scalability, developer Todd Hoff summarized Lambda as âPaaS++â â implying that Lambda is a souped up version of a platform-as-a-service (PaaS) cloud, which abstracts away the hardware underlying applications and merely executes lines of code. Even as he acknowledged its potential, Hoff had caveats. For the moment, Lambda has a limited reach, he wrote, given that it currently only supports the Node.js server-side JavaScript runtime and just a handful of events.
But even with those current shortcomings, Lambda might offer developers capability thatâs been hard to pull off, at least on the part of a major cloud infrastructure provider.
âNode meets IFTTT as a service?â was how Adrian Cockcroft, a technology fellow at Battery Ventures and formerly Netflixâs cloud architect, put it in a brief email.
Such power could be attractive to developers looking for a cloud to house new applications. But at the same time, it could lock them into Amazon. Itâs unclear just how time-consuming it would be to move processes in Lambda off of Amazon and onto another cloud or even a companyâs internal data center.
Aneel Lakhani, a former Gartner analyst who now works in marketing at startup SignalFuse, certainly saw the lock-in potential.

Even so, that doesnât mean Lambda wonât help developers create sophisticated applications with an impressively small amount of programming.
âIt will enable lots of innovation and experimentation as people learn how to take advantage of using AWS as the execution fabric for their code snippets,â Bernard Golden vice president of strategy for ActiveState, wrote in an email to VentureBeat.
