Cloud Computing Analysis of Light Curves for the Variable Stars by the CoLiTec Virtual Observatory Platform

An extending of the available cloud services and the appropriate resources gives us a possibility to move as many calculations and computational processes from the desktop tools/applications as possible directly to the cloud, servers or even clusters. In this work we present an information about the cloud processing, Virtual Observatories and Software as a Service (SaaS) technological model in astronomy, analyzed them, prepared a few interesting approaches of its implementation in scope of the Collection Light Technology (CoLiTec) project as the final tool named as “CoLiTec Virtual Observatory Platform” (CoLiTecVO). An implementation of the realized computational algorithms for creation of brightness curves for the studied variable stars in the CoLiTecVS (CoLiTec Variable Stars) desktop software was inserted into the SaaS structure of the CoLiTecVO platform in the cloud using the web interface. The CoLiTecVO platform was successfully verified with the different types of astronomical information for a big number of the studied variable stars in the various observatories in Slovakia, Ukraine and even Thailand using several kinds and sizes of telescopes as well as the different conditions during the observations.
