Open Source Soap Server And Client

As a software developer or DBA, one of the essential tasks is to deal with databases, such as MS SQL Server, MySQL, Oracle, PostgreSQL, MongoDB, and so on. As we all know, MySQL is currently the most widely used and the best free open source database, in addition, there are some you do not know or useless but excellent open source database, such as PostgreSQL, MongoDB, HBase, Cassandra, Couchba ...

The Abiquo company's main job is to help users build, manage, and extend complex computing architectures. Specific open source cloud computing products have the following three categories, respectively, Abicloud, Abintense and Abidata. These three types of products functionally can be used as architecture and the development of public-private hybrid cloud and cloud applications infrastructure. Abicloud is an open-source cloud management software that can be used to create and manage resources and to scale on demand. Abintense is a similar architecture to the grid to ...

As a new computing model, cloud computing is still in its early stage of development. Many different sizes and types of providers provide their own cloud-based application services. This paper introduces three typical cloud computing implementations, such as Amazon, Google and IBM, to analyze the specific technology behind "cloud computing", to analyze the current cloud computing platform construction method and the application construction way. Chen Zheng People's Republic of Tsinghua University 1:google cloud computing platform and application Google's cloud computing technology is actually for go ...

Eucalyptus Elastic Utility Computing architecture for linking Your Programs to useful Bae (Eucalyptus) is an open source software infrastructure, Used to compute the flexible, practical cloud computing of a cluster or workstation cluster. It was originally a research project at the University of California at Santa Barbara School of Computer Science, ...

With the popularization of Internet applications, more and more people start to use the services provided on the Internet. However, most of the Web sites currently providing services use user names and passwords to identify users, which makes it necessary for users to enter their username and password frequently. Obviously this kind of authentication has the disadvantage: with the increase of user network identity, users need to remember more than one group of user names, passwords, which give users the burden of memory; another frequent input user name, password, will correspondingly increase the user password password is cracked probability. In order to change this situation, single sign-on technology emerged ...

One, the charm of the management of cloud computing is that users can start using their ID card and credit card, but that's the problem. Such a simple service is bound to bring many challenges to the unprepared IT department. 　　We've been through this many times before: the benefits of a technology that are easy to use end up being an unexpected management challenge, such as virtualization, which causes virtual machines to become fragmented, new security risks to smartphones, and instant messaging that triggers corporate governance problems. This article is intended to show IT managers how to maximize cloud computing ...

Introduction Cloud application developers and DevOps have successfully developed tens of thousands of applications for IaaS (Amazon AWS, Rackspace, etc.) and PAAs (Azure, Google App Engine, Cloud Foundry, etc.) platforms. These platforms provide basic security mechanisms such as authentication, Dos attack defense, firewall policy Management, logging, basic user and account management, but security concerns remain the primary obstacle to enterprise cloud implementations. Security concerns for the cloud, deploying from a secure configuration ...

Before introducing, we introduced the three main features of Windows Azure in the Introduction to Windows Azure platform. That's computing, storage, and management. So far, through the previous teaching articles, you have become familiar with the storage capabilities of Windows Azure. Of course, storage is just one of the most basic functions. To give full play to the power of cloud computing, we have to learn how to "compute". Also in the Windows Azure platform profile, we have introduced the three main computational work of Windows Azure ...

Abiquo is a framework that helps users build, manage, and scale complex calculations. Specific forms of open source cloud computing products are mainly three categories, the corresponding products are abiCloud, abiData, abiNtense and so on. All three of these products can be used to structure and develop the infrastructure for public-private, hybrid, and cloud applications. abiCloud is open source cloud management software that creates management resources and scales as needed. abiNtense is a Grid-like architecture designed to reduce the number of high-performance meters.
