INDICES: Applying DDDAS Principles for Performance Interference-aware Cloud-to-Fog Application Migration

An increasing number of interactive applications and services, such as online gaming and cognitive assistance, are being hosted in the cloud because of its elastic properties and cost benefits. Despite these benefits, the longer and often unpredictable end-to-end network latencies between the end user and the cloud can be detrimental to the response time requirements of the applications. Although technology enablers, such as Cloudlets or Micro Data Centers (MDCs), are increasingly being leveraged by cloud infrastructure providers to address the network latency concerns, existing efforts in re-provisioning services from the cloud to the MDCs seldom focus on ensuring that the performance properties of the migrated services are met. This chapter demonstrates the application of DDDAS principles to address these limitations by: (a) determining when to re-provision; (b) identifying the appropriate MDC and a suitable host within that MDC that meets the performance considerations of the applications; and (c) ensuring that the cloud service provider continues to meet customer service-level objectives while keeping its operational Shashank Shekhar Siemens Corporate Technology, Princeton, NJ, USA, e-mail: shashankshekhar@siemens.com and Ajay Dev Chhokra Vanderbilt University, Nashville, TN, USA e-mail: ajay.d.chhokra@vanderbilt.edu and Anirban Bhattacharjee Vanderbilt University, Nashville, TN, USA e-mail: anirban.bhattacharjee@vanderbilt.edu and Yogesh Barve Vanderbilt University, Nashville, TN, USA e-mail: yogesh.d.barve@vanderbilt.edu and Shweta Khare Vanderbilt University, Nashville, TN, USA e-mail: shweta.p.khare@vanderbilt.edu and Guillaume Pallez INRIA, Bordeaux, France e-mail: guillaume.pallez@inria.fr and Hongyang Sun Vanderbilt University, Nashville, TN, USA e-mail: hongyang.sun@vanderbilt.edu and Aniruddha Gokhale Vanderbilt University, Nashville, TN, USA e-mail: a.gokhale@vanderbilt.edu and Gabor Karsai Vanderbilt University, Nashville, TN, USA e-mail: gabor.karsai@vanderbilt.edu
