Based On The Service Platform Of Cloud App Store Research And Implementation Of The Developer Community

With the Internet technology’s large-scale popularization, social network quicklybecomes a popular Internet application. According to the statistics, in2011, theutilization rate of social network of47.6%in all Internet applications. The rapiddevelopment of social network services, gradually make people consider its real valueand get ready to apply it in enterprise. But for small and medium-sized companies, theintroduction of SNS system is facing many problems, such as cost of one-timeinvestment and maintenance is too much, the end user quantity of growth is too fast,access request in a very short amount of time sharply increases, user access time is notfixed, and concentrated. Due to the above problems, undoubtedly, introducing SNS is atechnical challenge for small and medium enterprise.In order to solve the problems of introducing SNS in enterprise, from technicalperspective, this thesis chooses computing clouds which is primarily in design cloudcomputing model for enterprise development and all applications. In this thesis, on thebasis of frame of Hadoop, we can develop software system, for mass data and the taskof large quantities, Hadoop has high efficiency processing. Plus, in application softwaredeveloper community store, because this system involves a lot of small documenthandling, for small file processing considering Hadoop’s efficiency is special low. Sothis thesis puts forward the related algorithm, on Hadoop, to solve the single small fileand small batch documents, the main idea is through the merging small file into largefiles, and for small files we create index, makes the system as soon as possible to findsmall file, this thesis used the Trie tree to search index files and operate. In Hadoopprocess small documents is divided into two parts: one is merging small files into largefiles, two is to use MapReduce for small files create index, and the global index slice.Ultimately, it makes the index and data node of storage the file in close distance. Finally,this thesis analysis and research the problem about more tenants, we put forwardapplication software developer community system of SaaS store model for more tenantsaccessing, and solve tenants’ data isolation and share of SaaS.This thesis uses open source Hadoop platform to realize an enterprise application development. In this subject, we set up Hadoop platform belong to enterprise, andconfigure its environment configuration. Finally, deployment and realization based onthe service platform of cloud SNS system, this system provide service for the end userthrough SaaS software as a service way. Solve the questions of introducing SNS inenterprise. Through the use of the cloud computing platform in this article, makes SNSusers eventually get simple, rapid and effective services.
