Abstract [en]

Software as a service (SaaS) has become a common business model for application providers. However, this success has lead to scalability issues for service providers. Their user base and processing needs can grow rapidly and it is not always clear how a SaaS provider should optimally scale their service.

This thesis summarizes the technological (both software and hardware) related solutions to scaling, but will also cover financial and managerial aspects of scalability. Unfortunately, there is no existing out of the box solution for managing scalability, every situation and application is currently viewed as a unique problem, but there exists a lot of good advice from many sources about scaling. Obviously there are practical solutions to scaling, as there are successful SaaS providers, but it is not clear if there exists some fundamental principles that every SaaS provider could use to address the issue of scalability. This thesis seeks to find such fundamental principles though previous research, articles and finally a case analysis of Quinyx FlexForce AB. The thesis concludes that there are many principles of scaling a 3-tier web system and that most principles can be applied by SaaS providers.

Abstract [sv]

Software as a Service (SaaS) har blivit en allt vanligare lösning för företag. Detta har dock lett till skalbarhets problem för många leverantörer av SaaS. En SaaS leverantör kan få problem med skalning ifall deras användarbas eller beräkningsbehov växer för snabbt.

Denna avhandling sammanfattar de tekniska (mjukvara och hårdvara) relaterade lösningar på skalning. Avhandlingen kommer även kortfattat att omfatta ekonomiska och administrativa aspekter av skalbarhet. Tyvärr finns det inga befintliga universallösningar för hantering skalbarhet utan varje situation och tillämpning måste ses som ett unikt problem. Det finns många goda råd från många källor om skalning och uppenbarligen finns det praktiska lösningar på att skala, då det finns framgångsrika SaaS leverantörer. Det är dock oklart om det finns några grundläggande principer som varje SaaS-leverantör kan använda för att underlätta skalbarhet. Avhandlingen syftar till att hitta sådana grundläggande principer och grundar sig på tidigare forskning, aktuella artiklar och avslutats med en analys av Quinyx FlexForce AB. Avhandlingen drar slutsatsen att det finns grundläggande principer som SaaS leverantörer kan tillämpa vid skalning av ett ”3-tier” webserver system.
