Paper Title: An Efficient and Performance-Aware Big Data Storage System

Published  in: Cloud Computing and Services Science Communications in Computer and Information Science Volume 367, 2013, pp 102-116.

Abstract. Recent escalations in Internet development and volume of data have created a growing demand for large-capacity storage solutions. Although Cloud storage has yielded new ways of storing, accessing and managing data, there is still a need for an inexpensive, effective and efficient storage solution especially suited to big data management and analysis. In this paper, we take our previous work one step further and present an in-depth analysis of the key features of future big data storage services for both unstructured and semi-structured data, and discuss how such services should be constructed and deployed. We also explain how different technologies can be combined to provide a single, highly scalable, efficient and performance-aware big data storage system.  We especially focus on the issues of data de-duplication for enterprises and private organisations.  This research is particularly valuable for inexperienced solution providers like universities and research organisations, and will allow them to swiftly set up their own big data storage services.

There are many reasons why someone would want to convert a video into a GIF animation. The main one is so that people can put an animation of a video online without streaming the video itself such as on Twitter,Weibo. but for those not acquainted with the process, it can seem difficult.

I have developed a website for online Video to Animated GIF converting service.

Cloudpapa (http://www.cloudpapa.com) is a powerful online service built in the Cloud Computing environment to convert video file to animated GIF file. You can use this software to convert selected part or convert a single video file. Picture cropping, flipping are supported. You may also use it to make grayscale or sepia GIF file. It supports various popular video formats, such as avi, mp4, wmv, asf, mpg, dat, 3gp, flv, f4v, mov, mkv, rm, rmvb, swf, vob, webm. The interface is very user-friendly and easy-to-use.

Main supported video formats: 3GPP files (*.3gp,*.3g2,*.3gpp;*,3g,*.k3g,*,3gp2); AMV files (*.amv); AVI Files (*.avi); Digital Video Files (*.dv); DVD Video Files (*.vob); Flash Video (*.flv,*.f4v,*.swf); Matroska Video (*.mkv); MPEG Files (*.mpg, *.mpeg , *.mpe, *.m1v, *.m2v, *.m2t, *.tod); MPEG-4 files(*.mp4,*.m4v); NDS DPG Files (*.dpg); QuickTime Files (*.mov,*.qt); RealMedia file (*.rm,*.rmvb); VCD Movie Files (*.dat); WebM Video Files (*.webm); Windows Media Video Files (*.wmv,*.asf).

“Cloud Computing” is becoming one of the hottest buzzwords in the IT industry. It has been brewed over the last few years, now it is publicly recognized as the fifth paradigm shifts in computing. Some leading IT companies such as Amazon, IBM, Microsoft and Google begin to develop the cloud computing concepts with enormous investment. Also, in many countries, governments have launched many schemes to catalyse the development of this new technology. In this paper, fundamental concepts of cloud computing, utility computing and existing price models of major cloud providers are described.

Concepts of Cloud Computing

Cloud computing was first visualized by a Stanford professor John McCarthy, who predicted in 1961 that “Computation may someday be organized as a public utility”.

Even by now, cloud computing is still an evolving concept. For this reason the definition of cloud computing varies widely. From technical aspect, “Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.”

Utility Computing

Utility computing is the packaging of computing resources, such as computation and storage, as a metered service similar to a traditional public utility (such as electricity, water, natural gas, or telephone network) .Cloud computing and utility computing are similar. Users are able to request and use a specific amount of resource on demand as through services.
