A Novel Solution of Distributed Memory NoSQL Database for Cloud Computing

The traditional relational database to online storage are becoming increasingly problematic: the low performance do not gracefully meet the needs of mass data, the storage approaches of massive data are still not perfect presents. NoSQL and distributed memory database technologies have the potential to simplify or eliminate many of these challenges. NoSQL database technologies can provide Key-value style of data storage and largely ensure high performance. Distributed memory database technologies provide a means for easily store mass data in cloud in a dynamic and scalable manner. This paper argues for a new architecture called CDSA, which is a distributed memory NoSQL database architecture for Cloud computing to improve the performance of querying data and ensure mass data storage in cloud by using rational strategy. Furthermore, add or deleted any node from the distributed database cluster, the others node can work without stop service. We believe that CDSA can provide durable storage with high throughput and lower access latency.

The design of a trust and role based access control model in cloud computing

Today, the problem of trusting cloud computing is a paramount concern for most enterprises. Whether user behavior is trusted and how to evaluate users behavior trust are important research contents in cloud computing. This paper suggests an adaptive access algorithm by introducing the trust into cloud computing to decide the access control to the resources using an improved RBAC technique to solve more complex and difficult problems in the cloud computing environment. And the proposed model determines dynamically security level and access control for the common resources. Therefore, it is supposed to provide appropriate security services according to the dynamic changes of the common resources. This access control model bases on trust determines whether the user has the right to get access to the resource by dynamically authorizing. And this mechanism can control the users malicious behavior effectively.

A general M2M device model

At present, there are still many problems in the M2M system, and the most important of these issues is lacking a general M2M device model that could be widely used in various fields. So the main content of this paper is proposing a General M2M Device Model and discussing the function of each module in the model. Then the paper also discusses the communication of the General M2 M Device Model and gives three methods of networking.

An implementation of the online-payment platform based on SaaS

With the maturity of SOA and rapid development of Internet, a new type of software delivery mode named SaaS (Software as a Service) which provides the customers functionalities needed arises. It saves the cost of IT operation and suits to the small to medium firms very much. Ecommerce has grown extraordinarily nowadays with widespread Internet usage. In order to make trades more convenient and faster, Online-payment platform is needed urgently. In this paper, the protocol in the bank-side is analyzed, and then payment platform architecture is proposed which is based on the SaaS standard and supports distributed deployment. Finally, Key technologies applied to imply this platform are also described in detail.

Web Service discovery research and implementation based on semantic search engine

Common Services researched by Service Science have four major provision modes: web page mode, local client mode, web service mode and cloud service mode. Currently the most common used is Web Service mode. And now most Web Services provided by every Service Provider access and discovery strategy is still based on keyword searchs UDDI. Services returned to users often cant be called. This paper will raise a new Web Service access and discovery strategy which combines with Search Engine technology and Semantic Web technology. Search engine technology provides a search capability based on lexical analysis and grammar analysis while Semantic Web technology provides a matching and scoring capability based on semantic information. Search result lists returned to users will sort from higher score to lower score. This Web Service discovery strategy will improve services recall ratio and precision and it is very practical in engineering.

A framework of enterprise cloud application

Cloud computing is a significant trend with the potential to increase agility and lower costs. However, security risks, immature technology, and other concerns prevent widespread enterprise adoption of external clouds. One major reason is the lack of a systematic engineering process and tool supported by reusable architectural artifacts. Most existing Cloud computing platforms have not formally adopted the service-oriented architecture (SOA) that would make them more flexible, extensible, and reusable. By bridges the power of SOA and cloud in the context of enterprises application, extending enterprise security and control into the cloud This paper presents five framework principles and derives three interconnected framework modules to form a reusable and customizable enterprise cloud application framework. We also present some potential value-added services of the proposed the framework to guide strategic planning for enterprises moving to cloud.

An SLA based Web Service quality monitor system

Web Service is a kind of interface to achieve communication between the isolated information. It can be described, released, finded and invoked through Web. SLA(Service Level Agreement) provides a formal contract between service provider and consumer after negotiation, which states the quality, priority and obligation of the service. This paper proposed an SLA based Web Service quality monitor system to administer and evaluate the quality of Web Service. This design brings forward the parameters to be measured and some correlative protocols.

A solution for Mashup Platform based on SOA

Mashups is an emerging technology that enables users to create a new application based on a composition of contents retrieved from external services or applications. Mashup Platform allows non-programmer end-users to mash-up information sources and services to meet their information needs. However, with the increasing number of services, information sources and complex operations like filtering and joining, the automation of mashup is needed. In this paper, we designed an E-Commerce Mashup Platform for generating higher quality mashup services with users preferences in less time and in an automatic way. The platform consists of an Orchestration Component and several Atomic Service Components. The platform is flexible and extensible thanks to the SOA based atomic reusable and sharable service components. And it employs efficient P2P interaction between two components. Implementation example demonstrates that the system possess effective capabilities in composition time, ease-of-use and usefulness.

A carrier-grade service-oriented file storage architecture for cloud computing

Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. So, we can also use the cloud computing to solve the problem of large-scale file storage. Cloud-based file storage system is a high reliability, high consistency and high availability large-scale file storage system. In this paper, we design a service-oriented file storage architecture for cloud computing, for dealing with the problem of the file storage in a carrier-grade information system. Furthermore, we provide solutions to prevent system crash.

Policy-Based Market-Oriented Cloud Service Management Architecture

Policy-based management technologies represent an important tool for managing the user services that cloud-application frameworks provide. However, current policy-management system is a poor fit for the domain because they don’t support market-oriented management in cloud environments. The Policy-Based Market-Oriented Cloud Service Management Architecture (PBMOCSMA) can manage services in domains where users’ requirement is dynamic and flexible, policy specification is distributed and management decision-making is shared between users and service providers. This article describes the PBMOCSMA schema and architecture, showing how it provides flexible, dynamic, and extensible policy-based management capabilities to those who provide user services on the cloud.
