Design And Implementation Of Instant Messaging System Based On The Private Cloud Storage

With the continuous developm ent of network techn ology and unceasing enhancement of the degree of enterprise info rmatization, the enterprise internal office communication mainly has three system s: ①The enterprise E-mail system; ②The enterprise OA office system; ③The enterprise in stant messaging system. For the requirement of real-time and agility, the application of instant m essaging system occupies a very important position. The traditional instant messaging system exists the following problems:I. The session inform ation is recorded on the client If the clien t system isdamaged or local session log file is dele ted, the session history information willbe lost.II. 1 term inal send an attachment to th e n term inals, after these terminalsfinishing receiving, n attachments existed, a waste of storage resources.III. 1 term inal send an attachment to the n te rminals, will accoun t for the nnetwork bandwidth, causing pressure on network bandwidth.IV. files will be scattered on term inal. This will be caused more hidden dangerfor the enterprise’s information security.Since the personal com puter reform and the change of Internet, cloud com puting, which is an important part of China’s strategic emerging industries, has been seen as a third IT wave. It will cause fundam ental changes in life and production style and business model and become the hot topic of the whole society. Currently applications of public cloud are very broad and private cloud has been seen as the focus and e mphasis of informatization construction by enterprises, which have began to transplant the traditional business system to private cloud platform.Therefore, this article, based on the private cloud st orage of instant m essaging system design and im plementation, has built a private c loud storage platf orm using Hadoop technology, designed and implem ented an instant messaging system based on private cloud storage, which can solve pr oblems existing in the tra ditional instant messaging system. Private cloud storage-ba sed instant m essaging system has the following practical value:I. saving storage resources. II. centralized storage management of structured data and unstructured data generated in the application process, to avoid loss of data. III. is more conducive to the information security of the data. IV. reduce a lot of pr essure on the network load caused by the attachm ent network transmission. V. dynamic expansion, support application expansion.
