Businesses are craving means to effectively leverage multiple clouds in the modern era of computing. In response, loads of vendors are rushing to market with multicloud management tools of questionable efficacy. For software developers, building applications that draw on a number of clouds might be easier if they construct them out of serverless architectures to dynamically manage the machine resources powering those clouds.

A Cloud Guru Ltd. is an online educational community offering courses in cloud computing. The entire business runs on serverless computing. While it began on the Amazon Web Services Inc. cloud, it uses others now, such as Firebase Inc. and Google Cloud Platform. Building serverless apps with a set of managed services is, by its nature, more amenable to multicloud than generic cloud computing, according to Sam Kroonenburg (pictured), founder and chief executive officer of A Cloud Guru.

“I think because when you build serverless, you’re building against managed services effectively with [application program interfaces], [so] you can build against a managed service in AWS and hit its API, or you can hit one in Google,” he said.

Kroonenburg spoke with Stu Miniman (@stu), host of theCUBE, SiliconANGLE Media’s mobile livestreaming studio, at the ServerlessConf event in San Francisco. They discussed the flexibility and cost-savings possible with serverless computing. 

Infra-free switch hitting

Serverless allows companies to flip their architecture easily. A Cloud Guru’s platform was originally built as a serverless monolith. “It was a whole bunch of functions reading to and writing to the same database and just highly coupled,” Kroonenburg said.

Once developer teams came aboard, the company switched to a microservices architecture that allowed it to specialize in different areas. They completed the entire transformation incrementally without having to think about underlying infrastructure, load balancers, etc.

A Cloud Guru offers courses in different public clouds, such as Google Cloud Platform and Microsoft Corp.’s Azure. The serverless space is more vendor-agnostic than cloud computing generally and allows companies to architect liberally across all of the different clouds, Kroonenburg concluded.
