In the cloud, ensuring proper elasticity for hosted applications and services is a challenging
problem and far from being solved. To achieve proper elasticity, the minimal number of …

Achieving proper elasticity for cloud jobs is a challenging research problem and far from
being solved. In this paper, we focus on how to achieve proper elasticity for highly …

This paper shows how to properly achieve elasticity for network firewalls deployed in a cloud
environment. Elasticity is the ability to adapt to workload changes by provisioning and de …

The performance of network hosts can be severely degraded when subjected to heavy traffic
of today's Gigabit networks. This degradation occurs as a result of the interrupt overhead …

These days, both the cloud computing paradigm and MapReduce programming framework
have become key enablers for running big data analytics and large-scale compute-and data …

This paper presents two equivalent analytical models to study the performance of finite
queuing systems with Erlangian network services. Erlangian services are commonly seen in …

This paper presents and compares the performance of three popular packet rate estimators
used in predicting the rate of incoming traffic to a network host. The paper proposes a fourth …

The heavy traffic introduced by Gigabit networks can result in a significant performance
degradation of network hosts. This degradation happens as a result of the interrupt …
