Impact of Latency on Domains of Cloud Computing

Abstract

Cloud Computing is a model in which customers plug into the

“Cloud” to access I.T resources which are provided on demand

& charged as per use to enhance performance and speed. The Problematic   area   in   Cloud   Computing   is   the   aspect   of Performance.  So  far  looking  into  the  architecture  of  cloud computing,it consists of  cloud  end providing with the rented

resources,  end  user’s  using  the  resources  and  the  network connecting cloud to the end user. Impact of performance at the cloud end comes due to virtualization where the two vm’s  co- located   at   the   host   server   find   latency   problem   while

communicating with each other[3].At the network end latency can cause application to spend amount of time waiting for the responses from the distant center, then the bandwidth may not be  fully  utilized  and  performance  will  suffer[1].This  paper

presents an overview of areas in cloud computing  which can give rise to latency hampering speed and performance and how researchers  have  worked  to  eradicate  latency  at  cloud  and network end but there is still a loop hole at the user end which

can create latency problems through service disruption attacks like  Dos  and  DDos  and  thus  need  some   proper  security mechanism at the users end to stop this type of attacks
