Risk assessment in cloud computing (Published)

The primary purpose is to discuss the risk assessment in cloud computing and the issues which were tangled in multiple functional domains and to understand its current impact. This paper explores the following areas: cloud computing, characteristics of cloud computing, service models of cloud computing, risk assessment in cloud computing etc. There are many more areas, which can be explored in detail, where it can be used to generate better theoretical concepts and applications. This document will examine how the risk assessment methods of the cloud computing which are presently reoccurring over the Internet and discusses some of the issues with the Cloud Computing security features. This article presents some common elements for effective measures and outcomes.

A Comprehensive Survey of Cloud Monitoring (Published)

Cloud monitoring is an undertaking that helps to maintain applications active and perform constantly well. Cloud monitoring services collect a range of information about applications’ performance, storage, servers and networks within a provider’s ecosystem. A well-designed monitoring infrastructure, which does the aforementioned prerequisites, must be scalable and support various important performance parameters. Cloud monitoring is essential for both cloud users and providers. Along with, it is a central tool for managing software and hardware infrastructure. Moreover, it furnishes information and key performance indicators for cloud layer services. In cloud computing, monitoring has two types namely high-level and low-level monitoring. The high-level monitoring is for virtual platform status while the low level is related to the physical infrastructure. Furthermore, two types of cloud network monitoring are underlay and overlay. In this paper, the authors present a comprehensive survey and discussion in respect of high level, low level, underlay and overlay cloud monitoring. A generalize metric grouping for high level, low level, underlay, and overlay cloud monitoring were established.
