Job Schedule and Cloud Auto-Scaling for Repetitive Computation

Detta är en Kandidat-uppsats från Linköpings universitet/Institutionen för datavetenskap

Sammanfattning: Cloud computing’s growing popularity is based on the cloud’s flexibility and the availability of a huge amount of resources. Today, cloud providers offer a wide range of predefined solutions, VM (virtual machine) sizes and customization differing in performance, support and price. In this thesis it is investigated how to achieve cost minimization within specified performance goals for a commercial service with computation occurring in a repetitive pattern. A promising multilevel queue scheduling and a set of auto-scaling rules to fulfil computation deadlines and job prioritization and lower server cost is presented. In addition, an investigation to find an optimal VM size in the sense of cost and performance points out further areas of cloud service optimization.
