Abstract [en]

A point-of-sale (POS) system is a transaction system allowing retail transactions to be completed. The purpose of this degree project was to examine the potential benefits and risks of implementing a POS as a cloud-based application in comparison to a traditional on-site POS solution. The main focus of this project was put on identifying the benefits and possibilities of using a cloud solution but effort was also geared towards exploring the functionality of an existing web-based POS prototype as a cloud client. A further aspect of this project was to address some of the problems associated with the use of peripheral equipment while maintaining a thin client. This has been achieved by studying cloud computing theory in modern day literature, analysing and working with traditional POS solutions and doing hands-on testing with peripheral equipment. The project results supports the notion that a cloud based POS solution is not only feasible but may perhaps provide some benefits in comparison to a traditional POS solution. However, great care must be taken, both to avoid vendor lock-in and in designing a cloud based system to allow continued operation of client and eventu-al peripheral equipment in an Internet Service Provider (ISP) or Cloud Service Provider (CSP) outage situation.

Abstract [sv]

Ett Point-of-sale (POS) system är ett system som möjliggör fullförande av transaktioner. Syftet med detta examensarbetet var att undersöka möjliga fördelar och risker med att implementera ett POS system som en molnbaserad applikation i jämförelse med en traditionell POS lösning. Huvudfokus lades på att identifiera de fördelar och möjligheter en molnlösning medför men arbete riktades även mot att utforska funktionaliteten hos en existerade webbaserad POS prototyp i rollen som molnklient för detta projekt. En ytterligare aspekt var att adressera några av de problem som associeras med användandet av tredjeparts periferiutrustning tillsammans med en tunn klient. Detta har gjorts genom att studera cloud computing i modern litteratur, analysera och arbeta med traditionella POS lösningar och genom praktisk testning av periferiutrustning. Projektets slutsatser stödjer iden att en molnbaserad POS inte bara är genomförbart utan kan under vissa förhållanden medföra vissa fördelar gentemot en traditionell POS. Men, viss eftertänksamhet är på sin plats vid övervägandet att bygga och använda ett molnbaserat system för att garantera fortsatt operation av klient och periferiutrustning vid förlorad kontakt med internetleverantör och/eller molntjänstleverantör.
