This bundle contains for every step in the structured literature review (SLR) a bibliography file. Here are the three URLs for the search on the respective search engine: Search strings on the three search engines: https://ieeexplore.ieee.org/search/searchresult.jsp?action=search&newsearch=true&matchBoolean=true&queryText=(%22All%20Metadata%22:%22Function%20as%20a%20Service%22%20OR%20%22All%20Metadata%22:%22FaaS%22%20OR%20%22All%20Metadata%22:%22Serverless%22)%20AND%20(%22Full%20Text%20.AND.%20Metadata%22:%22definition%22)&highlight=true&returnType=SEARCH&matchPubs=true&rowsPerPage=100&pageNumber=1&returnFacets=ALL https://dl.acm.org/action/doSearch?fillQuickSearch=false&target=advanced&expand=all&AllField=Abstract%3A%28%28%22Function+as+a+Service%22+OR+%22FaaS%22+OR+%22Serverless%22%29%29+AND+AllField%3A%28%22definition%22%29 https://scholar.google.de/scholar?hl=en&as_sdt=0%2C5&q=%28%22Function+as+a+Service%22+OR+%22FaaS%22+OR+%22Serverless%22%29+AND+%22definition%22&btnG= The result of each step: Step 1 contains the raw list of all 471 entries. Step 2 contains a list of 40 papers after filtering the papers from step 1 Step 3 contains a list of 19 papers after skimming the papers from step 2 and selecting the relevant ones Step 4 contains the snowballed papers, in total 27 Step 5 contains the final set of 23 papers where the snowballed papers were assessed. The PDF (slrDefinition) shows the process of the SLR, whereas the spreadsheet (slr_faasConceptualization) contains all the information why papers where included/excluded as well as the characteristics identified in each paper. Furthermore, it includes the two CNCF definitions for Serverless and Function as a Service for archiving purposes.
