Cloud computing platforms provide easy and transparent access to a company's storage infrastructure through services. Commonly known as Storage as a Service (STaaS), it allows users to store their data at remote disks and access them anytime from any place. On the other hand, with the deployment of Electronic Document Management (EDM) to manage the insertion, sharing, and retrieval of information...
In order to provide the cloud computing research community with a full-system level datacenter server emulator with programmable hardware and software, and stimulate more innovative research work, this poster and demo shows a scientific research platform, Titian2, designed and implemented at ICT of CAS. Titian2 has the ability of on-line profiling and measuring, and the scalability of connecting with...
Due to its special characteristics, offering Hadoop-as-a-Service (HaaS) in a virtualized environment is more challenging than providing any other kinds of cloud services. This paper describes those challenges and presents solutions to them, ranging from an experimental project to open source and commercial enterprise systems to public cloud providers.
Modern datacenters employ server virtualization and consolidation to reduce the cost of operation and to maximize profit. However, interference among consolidated virtual machines (VMs) has barred mission-critical applications due to unpredictable performance. Through extensive measurements of RUBBoS n-tier benchmark, we found a major source of performance unpredictability: the memory thrashing caused...
Network Function Virtualization (NFV) is utilized to simplfy the deployment and management of constantly evolving and highly complex networking services. In this paper, we propose a dynamic load management framework for IMS networks using NFV, where IMS functions are created within a single virtual machine (VM) instance and moved to the cloud environment. Requests coming from the IMS clients are first...
Migrating to the cloud is becoming a necessity for the majority of businesses. Cloud tenants require certain levels of performance in aspects like high availability and service rate and deployment options. On the other hand, Cloud providers are in constant pursuit of a system that satisfies client demands for resources, maximizes availability, minimizes power consumption and, in turn, minimizes the...
Data is abundantly present in today's world and the amount of data we generate continues to grow. The representation and structure of this data, however, differs greatly depending on the software or platform. The wide variety of software available shows there is no one optimal way to model data for all software, but when you want to deploy software in the cloud using a Platform-as-a-Service (PaaS)...
This paper presents a novel evaluation study of the Cloud Computing technology, with a focused emphasis on the Cloud Storage mechanisms and the way they are affecting the progress of the present Cloud Services. Considering the exponential growth of the user data and its impact on the Cloud Storage infrastructure, this work provides two major contributions through comprehensive performance evaluations...
Network monitoring data provides insights into the network operation status. With increasingly sophisticated ways of probing, sampling and recording network activities, the huge amount of monitoring data brings both an opportunity and a challenge for network data analysis. We aim to build a scalable platform, named Analysis Farm, for analyzing network logs. Analysis Farm's targets include fast log...
The high cost of creating and maintaining software and hardware infrastructures for delivering services to businesses has led to a notable trend toward the use of third-party service providers, which rent out network presence, computation power, and data storage space to clients with infrastructural needs. These third party service providers can act as data stores as well as entire software suites...
