Introduction JACON is one of the most famous online food delivery system in Malaysia. This food system provides services to the customers by supplying foods in quicker and easier with cheapest rate. JACON has numerous branches all over the Malaysia. The speciality of JACON covers northern, southern and western styles of food. The system has both client and server side. The function of the system is to allow the user to place order by using the food delivery system. Besides, the system also allows the admin to make changes of the food menu and generate order report.
Problem Statement By using the system for JACON, it helps in serving food to customer at any time during business hour. There might be a problem while the shop has insufficient seat for the customer which might not satisfy for their services. By using online delivery system, it eliminates misunderstanding and no frustrations when ordering. While dine in restaurant, there might be chances the waiter has taking the wrong order due to the crowded environment. An online menu is cheaper and easier to create and maintain, in the shop itself, there are a lot of printed menu given to customer to order, therefore while a new food item is released the whole menu needed to be changed but an online order menu is easier to manage the information. Online delivery system is one of the best way to promote JACON as everyone is concern on using mobile every day. For example, Mc Donald’s and Domino pizza serve both walk in customer and online customer which help in increase their sales.

3.0 Concept of Distributed Computer System 3.1 Remote Method Invocation (RMI) Remote Method Invocation is using JAVA programming languages and development environment. Normally it is object oriented programing that able to interact with different machine in distribute network. Therefore, it can be treat as API to allow the object to implement a method on another object in the different address space so it can be use in remote machine or same machine. By using RMI, java virtual machine (JVM) can run an object in the computer which is client side can call a method on an object that present in another machine which is server side. Besides, RMI will create a public remote server object that make the communication between client and server side through calling the object in simple method. There are two important object required to use for communication which are stub object and skeleton object (javapoint, 2017). The stub object on the client machine builds an information block and sends information to the server and skeleton object required to pass the information from stub object to remote object. For example, while user log in to the system a log in request will send to server to get verification of the login details. After verified, the server will return the result to user and allow the user to log in to the food delivery system. During the passing request from skeleton object from stub object to remote object, it performs tasks which called the desired method on the real object present on the server and it forwards the parameters that received from stub object to the method (Geeksforgeek, 2017). The diagram below showed how RMI working.

3.2 Socket Socket is one endpoint of two ways communication link between programs. Socket is a programming abstraction which used to implement low level IPC. Socket is used to exchange information to other process with a specific condition where both processes must have socket to perform the transference of information. Socket is divided into two different type which is client side socket and server side socket. Client side act as the end point of the conversation which it performs send request and receive response. After the process has completed, the socket will be destroyed and not activated unless the sending request process are created again (Badgerati, 2009). In order to setting up the socket in client side, TCPIP must be set for a socket to connect server on the port and corresponding to the appropriate protocol. If the connection has been successful connected with no error, the whole process of setting up in client side is completed and ready to send request to a specific webpage though socket. In the system, one of the example is new customer able to register by sending request to system and wait for response, when response is being processed the socket will receive from system and display the registration page. After completed, the socket will be discard. On the other side, server side socket will listen the instruction from host to perform task given by the client side which only wait for command to perform actions. The food delivery act as server side to wait any command from user to execute specific process. Usually, the new socket works to exchange information with the client side. After complete a process, the socket from server will simply goes back to listen for more connections. To set up a server socket, TCPIP is required and bind the server socket to the host address and a port. When setting has completed, the server socket will ready to listen connection and set the maximum number that could be waiting. While the connection is connected by the server side, two block of information can be gather and ready to process. Lastly, when the process is finished, client connected socket must be shut down and close and when the handler has completed and return to the parents (Badgerati, 2009).

3.3 Serialization Serialization is a process of converting the state form of information into binary or textual form in order to transport over network. It able to transform a single or group of object into array of bytes or stream of bits for storing and sending over the network whereas array of bytes and stream of bits can transform back to the original state of information (docs.oracle.com, 2017). The process will perform automatically when ObjectInputStream and ObjectOutputStream classes is used in the system (stackoverflow, 2017). Therefore, the programmer able to decide to choose implement in the function by implementing the serializable interface. The process of serialization consists of marshalling and deflating of the object whereas the process of deserialization is inflating and un-marshalling. There are several benefits of using serialization which is it is easy to use and it is customizable. Besides, the serialized stream can be encrypted, authenticated and compressed, supporting the needs of secure Java computing. (Seshadri, 2012). By using serialization, it helps to improve secureness of the file to prevent information leaked. Lastly, serialization can be used to exchange object between different programming language such as C++ and java library with third part vendor library (Seshadri, 2012).

CT024-3-3-DCOMS Individual Assignment (TP032137- Chin Jess Nny) Stream Stream is one of the channel to allow every program to store data and ensure every program read data from the channel. Every stream has the ability to write data with different method and read from the source which is read method. When the channel is created, all methods need to be called to execute the process (MrBool, 2017). The diagram below showed how the stream work on a program.
Figure3.1: Stream representation (MrBool, 2017) Object Persistence Object Persistence is the ability to determine how the object are surviving when the application runs. The collected object will be collected by the JVM garbage collection during runtime when the object is no longer active. If the object did not collect and the API of persistence is used, it allowed to access to the application for the following time during the running process. Another benefit of implement persistence is able to store object in database which able to retrieve data at any time.

5.0 Comparison between DCOMS technology 5.1 Common Object Request Broker Architecture (CORBA) COBRA is an open distributed object computing infrastructure standardized by Object Management Group (OMG) and specification based on technologies proposed by software industry. CORBA provide independence platform as it using internal naming service for services client requests by providing middle layer between both client and server to determine server object. After that, it exposes method to client via it’s object adapter (POA). CORBA consist of potential maintainability as the server object able to make changes. The benefit of using CORBA is because it related to Object Request Broker (ORB) which support client and server network on separate machine to execute process whereas request service also need to be done from server program. Basically, it did not request to define where is the server and what interface used. During the execution of both request and return service required General InterORB protocol (GIOP) and Internet Inter-ORB protocol (IIOP). Both protocols must use together which enable to get request and replies to the Internet’s Transmission Control Protocol (TCP).
5.2Component Object Model (COM) COM is a binary-interface standard for software components which introduced by Microsoft in year 1993. COM is used to create re-usable software component and link components to build applications and take advantages of window service. The programming language used to create COM object is C++ to provide mechanism that help in simplify the implementation of COM object (Rouse, 2017). Microsoft Object Linking and Embedding provide service for user to display compound document, interface negotiation and life cycle management. The object is made up of set of data and its functionality is to manipulate data to perform task therefore COM object required to be accessed to the object data in order to execute more than one function. Hence, COM able to define how objects work together in distributed system and improving the security of the system (Microsoft, 2017).
25
CT024-3-3-DCOMS Individual Assignment (TP032137- Chin Jess Nny)
5.3 Distributed Component Object Model (DCOM) DCOM supports remote object by running on protocol name object Remote Procedure Call (ORPC). DCOM is the concept of Microsoft and the program interface in client side to request the service from the server side with another machine which connect network. DCOM is based on COM which provide set of interface to help client and server to communicate in one machine. By using DCOM interface, the client object able to forward Remote Procedure Call (RPC) to request service from server object. At the same time server object required to process and return result to client object. In other way, DCOM can work through network by using TCP/IP and HTTP method to execute the process. DCOM is similar with CORBA as it also provides distributed services. While the differences of DCOM and COBRA is DCOM is approach with network environment for program and data object whereas COBRA is sponsored by information technology industry which under Object Management Group (OMG) (TechTarget, 2017).
5.4 Justification on selected technology Based on several technologies, CORBA is selected as it able to implement in several programming languages such as C++, JAVA, C and others. In this system, Java programming language is more suitable for the food delivery system. CORBA is implement in the system as it is more efficiency technology compare to DCOM and COM. CORBA offer better performance and it is easier to link object and system together. CORBA protocol infrastructure ensure the transmission of message between client and server program in a compact representation therefore client and server able to receive information faster instead of wasting time while performing execution.

6.0 Virtualization & Cloud Computing Virtualization is the software to control the hardware to create various dedicated resources which is the fundamental technology to power cloud computing. It enables the computer to run multiple operating system and application at the same time. It helps to increase the computer hardware efficiency and flexibility. While the virtualization has several advantages, the purpose of using it is to avoid wasting costly processing power in the system. There are several virtualization areas in information technology area which are network, server and storage. First, network virtualization is to enable combination of available resource in network and separate the available bandwidth into channel which explain how the complexity of network is separated into manageable parts to handle which has the similar concept with manage files into different hard drive. Second, server virtualization is to enable hidden server resource from server users. The server resources including processor, operating system and identity of physical servers. The important of using server virtualization is to allow user have more resource sharing and utilization and maintain the capacity of the server. Lastly, storage virtualization is collecting physical storage from different network storage device to one network storage device. Basically storage virtualization will use in storage area networks (SANs) (Rouse, 2017). In general, virtualization is used to centralize task and help in improving the scalability of work at the same time (Angeles, 2017). In the food delivery system, virtualization concept can be implement in the system in order to improve the efficiency of the system as well as to help system admin to manage the order. Virtualization consist of several benefits which should be implement to improve the system.
There are differences between both virtualization and cloud computing. Virtualization is different with cloud computing as virtualization is software that manipulate hardware whereas cloud computing refers to a service that result from manipulation (Angeles, 2014). Besides, Virtualization can exist without the cloud, but cloud computing cannot exist without virtualization. The cloud computing is defined as able to share computing resources and deliver data as a service through internet. In this situation, cloud computing can be implement in the food delivery system in order to allow user to check the available food menu. System admin only required to select available food menu to the cloud and cloud are storing the data to display out to the user. Cloud computing consist of several benefits to for users such as capital expenditure free, able to work from anywhere without restriction and document control. While cloud computing able to save cost of hardware, user can just pay and enjoy subscription based 27
CT024-3-3-DCOMS Individual Assignment (TP032137- Chin Jess Nny) model without setup the computer hardware. Setting up a server could be a difficult task for user if user did not have any knowledge about it. Therefore, using cloud computing admin able to work anywhere with internet connection which convenience to work and able to store data. Cloud computing helps in manage document and store it centrally to avoid document messed up cause of conflict of file content and format. Besides, it helps to show the document more visible and user able to work better in the industry environment.

9.0 Benefit of Internet Communication Engine (ICE) ICE is a modern object oriented toolkit which enables to build distributed application with minimal effort. By using ICE, it allows to focus efforts on application logic as well as take care of interactions with low level network programming interfaces. ICE able to provide a better network infrastructure for demand technical applications which able to use in many ways such as C++, Java, highly efficient protocol, TCP/IP, SSL- based security, firewall solution and others. ICE is a comprehensive of Remote Procedure Call (RPC) which support multiple programming languages (Zeroc, 2017). Besides, it also supports several operating systems such as Window, android, Linux and others. ICE also provide several complementary service for network application such as Ice Grid, Ice Storm and IcePatch2 which consist of different functionality to enhance system such as monitoring, file distribution and event publish. There are several benefits of using ICE which are secure, efficient and minimize CPU and bandwidth consumption and flexible.
Secure Ice has good security and suitable to use over insecure public networks because it offers a powerful and easy manipulation in security feature. It can work with existing firewalls which a single port is enough to provide secure access for unlimited clients to unlimited servers. The IceSSL plug in use the operating system to encrypt data and authenticate connection which is an easy way to use as it just required few line of code to execute (Zeroc, 2017).
Efficient and minimize CPU and bandwidth consumption ICE use an efficient protocol to minimize the consumption of CPU and bandwidth. It used small amount of CPU with a highly efficient protocol which allows the application to scale up to ten thousand of client (Zeroc, 2017). The compression allows to disable and enable during runtime and without code to modify. The ICE also can receive and forward request to new destination as it not required to unmarshal and remarshal payload when forwarding.
Flexible ICE has a great flexibility as it supports both synchronous and asynchronous invocations. While using Synchronous invocation, caller thread able to blocks until the RPS has completed whereas asynchronous invocations allow caller to continue using the thread while RPC is

ICE can support both synchronous and asynchronous on the service side which server side able to read the request and locate it to execute with synchronous dispatch whereas asynchronous dispatch need callback for implementation and additional request. ICE is flexible to accommodate even though the most demanding and mission- critical application (Zeroc, 2017).
There are several alternatives for ICE include Delphi, Java and Python. While Python mapping is intuitive and client-side Slice-to-Python mapping will define how Slice data type will be translated to Python type and how clients pass parameter and handle errors

10.0 Future Enhancement Based on the scenario, I had analyzed several suggestions to improve the system. Based on my opinion, the system should allow guest login by linking social media account such as Facebook, google+ or Twitter instead of blindly register account through the system. System admin should have more authority to view the system instead of just handing generating report. Besides, both customer and admin are using different sign in page which might need more memory. It should be combined into 1 page for both login and the system itself decide the authority of both users. A notification should be given to the customer while the food order has been placed and during the delivery stage system should send notification to customer to inform them the order has been delivering to their footstep. The food delivery system should extend to mobile application which people nowadays are more preferred to use mobile application to perform action such as Foodpanda, Mcdonald’s, and Domino.

11.0 Conclusion After implement the Food delivery system, JACON able to provide online supplying food to customer in a quicker and easier way with a cheapest rate. The implementation with efficiency technologies, the system process will become more convenient and efficiency to use for the user and admin which enhance the performance of the system. Besides, there are several obstacles I met while researching on the technologies concept. The technology concept was confusing therefore I need to spend more time on understanding the knowledge of implemented technologies. There are several journal and ebooks helps me to have better understanding on the theories and also understand how it applied into the food delivery system.
