Fermyon Technologies this week launched a hosted platform-as-a-service (PaaS) environment, dubbed Fermyon Cloud, that promises to make it simpler to build WebAssembly (Wasm) applications.
Announced during the Cloud Native Wasm Day event during the KubeCon + CloudNativeCon North America conference, Fermyon Cloud is now available in open beta.
Fresh from raising $20 million in funding, Fermyon CEO Matt Butcher said IT teams can quickly build and deploy Wasm applications using a Fermyon Spin development tool and a Fermyon Platform the company launched earlier this year.
Fermyon Cloud adds an opinionated PaaS environment managed by Fermyon that can start up Spin applications in less than a millisecond. It uses a serverless application programming interface (API) that makes it possible to cache and optimize applications as they are loaded, noted Butcher.
Originally developed more than five years ago by the World Wide Web Consortium (W3C) to create a common format for browsers executing JavaScript code, Wasm is now used to rapidly build lighter-weight applications that can be deployed on any server platform. In effect, the promise of being able to write an application once and deploy it anywhere is finally being realized some 25 years after the initial introduction of the Java programming language.
Wasm isn’t necessarily going to replace existing approaches for building applications, at least not any time soon, but it does provide an alternative to serverless computing frameworks for developing lighter-weight applications that run faster.
In addition, at a time when organizations are becoming more concerned about application security, the appeal of Wasm is clear. Existing approaches to building applications rely on the aggregation of software components that tend to lack distinct boundaries between them. As a result, it becomes relatively simple for malware to infect all the components of an application. In contrast, Wasm code runs in a sandboxed environment that isolates execution environments to eliminate the ability of malware to laterally move across an application environment.
Wasm is especially well-suited for building lightweight applications that previously might have been deployed on a serverless computing framework, noted Butcher. The issue developers are encountering when using a serverless computing framework is that those frameworks are based on containers that have comparatively slow startup times, he added.
It remains to be seen how much traction Wasm gains in the months ahead, but Butcher said he expects most backend services, such as databases, will continue to be built using containers. Fermyon is betting, however, that many future cloud-native applications built by the average developer will be constructed using Wasm. In the longer term, Wasm will also soon be used to build applications infused with machine learning algorithms, said Butcher.
In the meantime, DevOps teams should get ready for more Wasm code to move through continuous integration/continuous delivery (CI/CD) pipelines. The challenge, of course, is that code will need to be managed alongside all the other software artifacts moving through those pipelines, as well.
