This article describes in detail how to deploy and configure ibm®spss®collaboration and deployment Services in a clustered environment. Ibm®spss®collaboration and Deployment Services Repository can be deployed not only on a stand-alone environment, but also on the cluster's application server, where the same is deployed on each application server in a clustered environment.

Blockchain is currently a relatively popular new concept, containing two concepts of technology and finance. From a technical point of view, this is a distributed database that sacrifices consistency efficiency and guarantees eventual consistency. Of course, this is one-sided. From an economic point of view, this kind of fault-tolerant peer-to-peer network just meets a necessary requirement of the sharing economy - a low-cost trusted environment.

The storage system is the core infrastructure of the IT environment in the data center, and it is the final carrier of data access. Storage in cloud computing, virtualization, large data and other related technologies have undergone a huge change, block storage, file storage, object storage support for a variety of data types of reading; Centralized storage is no longer the mainstream storage architecture of data center, storage access of massive data, need extensibility, 　　Highly scalable distributed storage architecture. In the new IT development process, data center construction has entered the era of cloud computing, enterprise IT storage environment can not be simple ...

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 ...

With the rapid development of multi-core processors, virtualization, distributed storage, broadband Internet and automated management, a new computing model-cloud computing is born. Cloud computing enables the deployment of computing resources on demand, allowing users to pay only for the resources they need. Fundamentally speaking, cloud computing refers to the user terminal through remote connection, to obtain the cloud storage, computing, database and other computing resources. Cloud computing from the distribution of resources can be divided into "cloud" and "cloud terminal." "Cloud" is a metaphor for the Internet or a large server cluster, which is distributed across multiple distributions ...
