History Of The Client Server Architecture

History Of The Client Server ArchitectureHures was development principal(prenominal) fix reckoner schema which was having besides many disadvantages and toyning cost. Because of this reason we decided to propose Client innkeeper Architecture which is widely used in the global environment.The thickening server calculation model is used most of the business frame. This engineering science was integrated with those point companies. It provide provide the multi go and huge storage capacity of info base. These corpses in addition handle the difficult GUI progress tools.Hence guest server Architecture having disadvantages too. Client Server mainly depends on the profits design. If they dont reserve the meet network design network traffic would make serious problem in the production environment.thitherfore i counsel client server computing device architecture is the best way to make the business development to the particular Hures Company.I. INTRODUCTIONThis assignmen t testament cover the main argonas of the computer architecture. I volition abbreviation and comparison those strategy for present technology. How this technologies used to developed the hures go with and at that place services. Norm both(prenominal)y I identified the two major ashes used by hures. Those are mainframe computer and client/server system.Mainframe computer, this type of computer how to sponsor the particular company , what is the main usage of this structure, how it will actuate the system compare to the raw(a) system and disadvantage of that architecture. Then the client server architecture is most famous method for the large companies. How easier and more in force(p) to manage inventory and track the software. Analysis the advantage and disadvantage and implement the new architecture for cover the current client server system.Hures will suggest using the intranet technology. I will analysis that technology how to military service the particular system a nd how that will effect the system. Also how the intranet software affect the client server system. I identify the problems and I will propose the new architecture instant of client server structure.1.0. Problem identificationThere are no unique behaviors to this specific problem because the Hures Company was run past twenty years. Now also it is running but the system is resembling what ever they have used before like mainframe computer and client server system. The new technology is introducing condemnation to time but that particular company was not change according to that advanced of technology. According to their customer amount on that point service want be increase but Hures used the old equal server system that will get outdated and those are not reorganized and improved with the time period of technology. Here whatsoever problem to using main frame computer.2.0. Main Frame ComputerThis type of computer normally used by large organizations for there business purpose. M ainframe computer have the capability to run the several operating systems thats mean central process units performing instruction at the same time this called parallel processing. There are very high volumes of input and output and emphasize throughput to hold the mainframe computers. Also mainframe has carrying out reliability for fault tolerant.2.1. Classifies of main frame computersystem having 1 to 16 CPUSthe lie RAM memory range is 128Mb to 8Gbprocessing power range is 80Mips to 550Mipsit contain different types of cabinets such(prenominal) as Storage, input/output and random ingress memoryIt has different process for different program such as task supervision, plan management, entertainment in installments, index, and inter address break and rumors.2.2. Advantage of the Mainframe computerthe biggest education processing systemcritical or difficult applications because of multi exploitersits stored enormous amount of data thats mean very big capacityhigh speed data process ing Ex-1GOPS (giga operation per second)this is a characteristic operating system and technology dispersal timeIt will do millions of data and concurrent communicationserving thousand of simultaneous exploitersthis system normally based on UNIX and Linux operating system2.3. Disadvantage of main frame computersThe whole system needs a large space for the storage capacity and large cabinets that addressed the central processing unit thats mean cryptographic maintain, I/O handling, Memory handling and supervising.The market prize is very expensive compare than other systems.the users using the port is still textit will work extraordinarily extensivethe power utilization is very hugeThere for hures company faced the problem with main computer because that are very large and it need very big space. Also the maintenance cost is very high and it will generate the loads of heat then the property will getting damaged.3.0. Client Server SystemThis is sharing application design. This shari ng is taking placed between the servers and client thats mean service providers and service requesters. Those are separate hardware rather than computer network. Server is a high routine host and it will run one or more programs in a particular machine, share the resources with clients. But client not share any resources with server but it fanny be request the resource form sever.Systems are created by assembling independent components, each of which contributes unique, specialized blend ins to the system as a whole. In the simplest arrangement, client components interact with users and with servers that manage various computing resources. In more sophisticated arrangements, some servers substructure also be clients of other servers. Clients and servers can use hardware and software uniquely suited to the required functions. In particular, reckon-end and back-end systems normally require computing resources that differ in type and power. Database management systems can employ h ardware specifically designed for queries, while graphics functions can employ memory and computing resources that can generate and display intricate diagrams. John Dryden, 1998According to the above statement it said the client sent request the service to the server and server will accept and sent the service response to the client. This processing method is called client server system.3.0.1. Sample Diagram Of client server systemClient server system has trine type of model such as3.0.2. superstar /One tire architectureThis technology mean by the server will rile by user at one time for some particular software application such as to use data, business logic and interface.3.0.3. Double / Two tire architectureThe server will access by client with the helper of two layer software application. It has two type application front end this is work together with client, back end- functions are used to store data. The advantages are function development speed, it will well on work on s tandardize environment reasonably business law, and system protective cover is very difficult on this model.3.0.4. N/Multi/Three tire architectureThe server will access by client with the help of three layers software application such as front end, component, back end. In this model, between the client and server another tire is used its called middleware. This tire function is the transaction processing, massage or application servers also it will manage the queuing, application implementation and database performance.3.1. Properties of Client Server SystemServer made a decision what is the client need according to there request and where is stored.independent stage for hardware and operating systemlocation of the server and client will see-through to he usersIt will work interchange function such client become a server, server become the client.this system has a scalability such as horizontally and vertically3.2. Type of client server communicationssocket is this fully comport t o the unix to unix communicationRemote produce cell is client will directly call the distance serverMassage oriented middleware3.3. Advantage and disadvantage of client server system.3.3.1. AdvantageServer is centralization like either thing control by serverScalability, whatever customer need in future sever can upgrade that application.Flexibility, upgrade the new technologyInteroperability, client, server and network are work together.Accessibility, the remote and cross multiple access to the serverdevelopment is easylow cost maintenance compare than mainframeuser friendly, every thing Is operate ever easy3.3.2. DisadvantageDependability, the server wick damage or down the hole system will down.Lack of mature tools , according to the change of new technology the tools also will changelack of scalability, operating system of the network is not scalable.higher projected costNetwork congestion due to the heavy buckram server by traffic.According to the hures client server system t here some problem, within the hures infrastructure the range of network and size are not enough to their better services. Also need some additional services such email server and multiple servers to multiple-le applications. Also change the server OS and improve the network connectivity, data transfers and general understanding of the both workstation system.4.0. secondary system for client server systemThe best way is to be selecting the n tire system that is help to implement the hures service. In this manner the system will change their OS and increasing the services to client. Also develop to using peer to peer system to allow more users to share access to database application. This type of connection will improve the scalability of the network and improve the software development.The N tire architecture is face for upgrading system without chaining the back end front end application. In this manner the new technology is introduce such as component based development. This syste m has some advantage such as according to the customer time to time requirements it is easy to upgrade, created one component will reused for similar application and the creator can using build in interfaces. According that the hures need more customers with better service then the hures server is going to be upgraded such as change the OS system and introduced the new network connection technology like WiMAX, high speed LAN.Change of OS mean by called to reuse the components again with some standards such asCommon Object request Broker ArchitectureRemote Method InvocationThe different programming languages are allowed to communicate the both CORBA and RMI standards.4.1. CORBAAny of the networks the computer application will communicate to work with independent. The standard communications protocol IIOP is used. This is an inbuilt functionality and fixed system. This will handle large number of clients and more reliability. Also this is trustworthy time system and used for large ap plication. It is normally working in the three layers such as presentation, application and Data layers. corba using some protocol such as internet intra object glass request broker protocol, square socket layer inter object request broker protocol and hyper text intra object request broker protocol.Benefits of CORBA areLanguage liberty several languages like C++ and java.Portable for any of the operating system such as java, linx, unix, mac, windows and sun. matched for all new technology and liberty of data transfer, it will help to multi application process.The architecture of the CORBAAbove the diagram describes the structure of CORBA. This is system will help to save the bandwidth and has a three interface such as operation, attribution and exception. There two new chance variables have been introduced in the market. Which are CORBA version 2.0 and CORBA version 3.Therefore the proposed system was very helpful to improve hures business such a way of improve the technology, qu ality and supply the multiple services.5.0. Internet meshing technologyThis the internal network of the particular company. This is a protected logons to access information. Many companies like hures, only the employees and management to operate the company essential information using protected site. It was designed a simple programming like HTML, java and cascading style sheet. In this manner interior the company network severs will provided array type of connection to the different saved database. This technology is very helpful for the business development because low cost and saved time.5.1. Planning and cosmea of intranet web technologyThis is a strategic significance of the particular company success on development and achievement. Also hardware and software are help to improve the planning likeprinciple and objective of the intranetthe management and realization responsible for who what to make like person or divisiondata construction, eccentric strategy and page layoutsD efining the intranet securityControlled the input new data or update the exiting data5.2. Characteristic of intranet technologyIntranet idea and technologies are same as internet. The protocols are same as internet protocols such as HTTP, SMTP and FTP. Main interfaces to inheritance data system hosting corporate information. Intranet has some characteristicThis is a better understood as a personal extension of the internet limited to a companyThis also differenced with extranets. Because intranet only used for employees and customers in inside the company. But extranet may access with clients, contractors and other accepted party.With the help of firewall intranet may provide the gateway to the internet on a network. After some user verification and encryption, the off-site employees can access the company information using virtual private network connectivity.5.3. How it is use full for an organizationIt is used as commercial civilization-transform platforms. Discus the key issues, idea about management, productivity, quality and all other issues to the large no employees of that particular company.It is used to distribute the tools and application.It is manage by human resources or CIO departments of the company.It is very complex interface compare to the company public internet.5.4. Benefits of intranet systemLabor force efficiency mean by user can find the information about their roles and duties.Time mean by whatever employee will need they will put in the site.Communication meaning by to communicate planned proposal that have a global collapse throughout the company.Business operation and management mean by ontogenesis and planning the application to carry the business.Cost Effective mean by the slued the coast rather than send the doc by post. Put all necessary documents on the intranet.Promote common corporate culture mean by all clients can see same information.Enhance team work. immediate updates.5.6. Intranet strategiesThe company objectives will achieve to help of hardware and software system. This is a same concept as internet to browse the web and severs and restricted for the particular company. To consult parties who going to be use the intranet system according to their budgeting. According the application it has four types of role.5.6.1. The role of the intranet systemcommunication and teamwork mean by audio video conferencing, conversation and chat rooms and to operate the email transfersweb give outing mean by create the hyperlinked multimedia application and data documents to publishbusiness process and administration mean by processing, controlling and accessingintranet portal management mean by control everything by particular administration5.7. The pros and cons of the intranet system.5.7.1. Pros impose the cost in this manner company will inform the necessary thing to employees and other, upload in the portal rather than paper printing. Also reduce the sales and promotion, employee preparation and organizati on costs.Simple to useEconomical to use.Reasonable hardware and software system costThe all protocol are support to operate because if internet like TCP/IP, HTML and FTP.Easy to access the Communication and operating intranet system.5.7.2. ConsAccording to the rapid technology this not support to the upgrading software. inadequate security facilitiesUser support and system performance is very poor.The scalability is not effectively.Time consuming.No PC compatibility for all employeesThis not fully support to the maturation organization.6.0. Effect of intranet web technology over the client server systemIntranet technology is an open network system. There no good network security system mean by not protected your company network system. The monitoring and controlling is very difficult because of access on outside sources. numerate the intranet usage in a particular company, if there large number of employees are working in that time everybody to be operate the intranet system. In t his time the system was faced some problem such asIf user using like that the particular server will get the heavy loaded because all user can request the service from server at the same time then server will able to answer the all request for certain time. Then it will overload. This happen will effect to outside service customer to that particular company.The server must manage to handle that situation by expanding the sever capacity and upgrade the new technology. Like upgrade the OS system.At the same time the server will head time to provide the service for those particular requests. It is normally called server response delay. This will affect the company services to outside.When the server is loaded then the there is the change to hardware crash of that particular system. Such as the hard disk and RAM memory will failure.User will plug their international interfaces to upload the threats/virus. Then is going to be shutdown your whole network system. Its called server down.W hen all users using at the same time that particular network will get the collision because of traffic. Then outside customer will get the service will receive in delay.The solution of this problem is the company will make sure the monitoring and secure the system. Using CCTV in various places inside the company and monitoring the users and give the priority usage. Then they can maintain the reliability of the company network.II. ConclusionBy doing this Assignment I came to understand the Client Server Architecture subject more clearly and got a good experience. I described the client server system to that operational specification, implementation and bad effects. I think those information are very help full for the basic understand of client server system. Also I suggest the alternative system and explain how it will help to work with one-time(a) system. i thick the hures company will upgrade the system, network connection and turn-into new technology it is very help full for the feature business approach. They reach the more customers and get more profit.III. Reference1. John Dryden. 1998 High -Performance client/server, John wiley son, chapter 2 p 29.2.
