Cloud Computing is computing where in several groups of servers are networked for providing online access to users. Several factors which influence cloud computing such as scalability, security etc are discussed by many researchers. Now a days usage of internet resources is widely increasing resulting in the increase of workload exponentially. In order to make cloud computing efficient and impr...

We present Hybris key-value store, the first robust hybrid cloud storage system. Hybris robustly replicates metadata on trusted private premises (private cloud), separately from data which is replicated across multiple untrusted public clouds. Hybris introduces a technique we call consistency hardening which consists in leveraging strong metadata consistency to guarantee to Hybris applications ...

with the increasing number of public cloud platforms and the growth in terms of computing capacity, I/O performance must be one of the main points to look at so that it keeps up with the current compute capacity. In order to start considering any of the existing public cloud platforms for its use in scientific or in general, any high I/O demanding application, we have to study their raw perform...

Smartphones have become popular in recent days due to the accessibility of a wide range of applications. These sophisticated applications demand more computing resources in a resource constraint smartphone. Cloud computing is the motivating factor for the progress of these applications. The emerging mobile cloud computing introduces a new architecture to offload smartphone and utilize cloud com...

Open source cloud platforms are playing an increasingly significant role in cloud computing. These systems have been undergoing rapid development cycles. As an example, OpenStack has grown approximately 10 times in code size since its inception two and a half years ago. Confronting such fast-pace changes, cloud providers are challenged to understand OpenStack’s up-to-date behaviors and adapt an...

Cloud computing has achieved great success in modern IT industry as an excellent computing paradigm due to its flexible management and elastic resource sharing. To date, cloud computing takes an irrepalceable position in our socioeconomic system and influences almost every aspect of our daily life. However, it is still in its infancy, many problems still exist.Besides the hotly-debated security...

Cloud management stacks have become a new important layer in cloud computing infrastructure, simplifying the configuration and management of cloud computing environments. As the resource manager and controller of an entire cloud, a cloud management stack has significant impact on the fault-resilience of a cloud platform. However, our preliminary study on the fault-resilience of OpenStack—an ope...

By building Moodle learning environment in the cloud platform , and the design of teaching process of the corresponding with the author's teaching practice in Moodle from the cloud platform selection, learning environment to build and curriculum design, with adult education computer course as an example, the blended learning based on Moodle was discussed, the teaching practice shows that cloud ...

Popular public cloud infrastructures tend to feature centralized, mutual exclusion models for distributed resources, such as file systems. The result of using such centralized solutions in the Google File System (GFS), for instance, reduces scalability, increases latency, creates a single point of failure, and tightly couples applications with the underlying services. In addition to these quali...
