A serverless architecture is a new approach to offering services in the cloud. It was invented as a solution to the problem that many organizations are facing today \u2013 about 85% of their servers have underutilized capacity, which is proved to be costly and wasteful. By employing the serverless architecture, the organizations get a way to eliminate idle, underutilized servers and thus, to reduce their operational costs. Many cloud providers are now jumping to the serverless world because they know it is going to be the future of software architectures. However, being a new approach, the serverless architecture is still relatively immature \u2013 it is in the early stages of its support by cloud service platform providers. This paper provides an in-depth study about the serverless architecture and how to apply FaaS in the real world.<\/jats:p>","DOI":"10.3233\/idt-210194","type":"journal-article","created":{"date-parts":[[2021,12,7]],"date-time":"2021-12-07T14:07:58Z","timestamp":1638886078000},"page":"825-838","source":"Crossref","is-referenced-by-count":1,"title":["Serverless, FaaS and why organizations need them"],"prefix":"10.1177","volume":"15","author":[{"given":"Irina","family":"Astrova","sequence":"first","affiliation":[{"name":"Department of Software Science, School of IT, Tallinn University of Technology, Tallinn, Estonia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arne","family":"Koschel","sequence":"additional","affiliation":[{"name":"Faculty IV, Department of Computer Science, University of Applied Sciences and Arts Hannover, Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marc","family":"Schaaf","sequence":"additional","affiliation":[{"name":"School of Business, FHNW University of Applied Sciences Northwestern Switzerland, Olten, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Samuel","family":"Klassen","sequence":"additional","affiliation":[{"name":"Faculty IV, Department of Computer Science, University of Applied Sciences and Arts Hannover, Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kerim","family":"Jdiya","sequence":"additional","affiliation":[{"name":"Faculty IV, Department of Computer Science, University of Applied Sciences and Arts Hannover, Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"key":"10.3233\/IDT-210194_ref1","doi-asserted-by":"crossref","unstructured":"Balzert H.
