Software engineers are interested in novel ways to convert their applications into formats that can run «serverless» on Function-as-a-Service. Many issues have to be considered – partitioning of the application functionality, short-livedness and memory constraints of functions, easy but limited language runtimes or rather difficult container wrappers around microservices. Our virtual guest researcher Leonardo Rebouças de Carvalho, from University of Brasília in Brazil, has recognised the issue and launched a community website faasification.com that contains a lot of tools, methodologies, articles, research insights and events related to shifting software into the world of FaaS. Bookmark that site if you are developing serverless software!
SPLab has been participating in two major events recently: DINAcon in Bern, the conference for digital sustainability, and the Software QS Day in Frankfurt – expanding horizons on software quality and testing. As we participated as attendee in the first and speaker in the second, this blog post summarises interesting technology trends from both.
The first four “wild” years of serverless computing, starting with simple Function-as-a-Service (FaaS) launches in 2014, are over, and we are in the fifth year now. All major cloud companies offer FaaS, corresponding Backend-as-a-Service (BaaS), and related “serverless” services such as frameworks for cloud function-based data processing at the edge or in constrained environments. Researchers from universities, research institutes and research divisions in companies have covered this development, and proposed improved systems and frameworks, since 2016 – trailing two years behind industry initially, but with promising designs and prototypes which may give the necessary impetus for a next-generation serverless computing paradigm. We have surveyed 130+ research papers and announce the Serverless Research Output website which makes the results accessible.
