Abstract

Development of the world's information and communication technology-based growing rapidly. The development of these technologies has given rise to another dimension in human life, namely the need for computer use. Application of machine vision applications where a computer has the ability to understand the data in the form of image and make decisions based on data obtained from a real object, in this case is generated through the capture image from webcam.            The images (digital images) of a real object through a webcam can be done in many ways capture the object. In this research object retrieval using an object of activity is captured on the webcam through the motions of objects. Digital image acquisition is performed with the tool in the form of software (Obtion Remote Version 1.0). Obtion (Object Detection) method works with the system of comparison between that time frame the previous frame captured by the camera at the time of recording the object. Comparison of the difference in the frame will be accommodated in a place that will be used to support the execution of an object by counting the number of pixels that exceed the value of the difference in number of field values with regulator frame to frame changes in the location of the object motionObtion Remote Version 1.0 will take a digital image of the object with trigger object motion detection performed. Digital image acquisition (capture the object with a webcam) will be done automatically if the object has been successfully detected. The detected object will be stored automatically in the directory are executed as a digital image storage.

Abstract

The increase o f request brings large traffic to networks especially to data centers, large enterprises and portal websites. In addition, server provides more and more information by using applications. Most servers have to provide all-day services, and any service interruption or key data loss in communication will result in business loss. All these require high performance and high reliability on application services. However, the increase of server processing speed and memory access speed is greatly lower than that o f the network bandwidth and applications. In addition, the increase o f network bandwidth makes server resource consumption more serious. Therefore, the servers become the network bottleneck, and the traditional single device mode becomes the network failure point. Load balancing (LB) comes to provide a good solution by providing multiple servers form a server cluster, with each server providing the same or similar services. A load balancing application is managed at the front end o f the server cluster to distribute user requests in the server cluster according to pre-configured load balancing rules, provide services, and maintain the servers. Load balancing bring good advantage such as bring faster application, low cost, the available resources will not be wasted, and no high-end devices are needed for the new resources. It is expandability. When services are increasing, the system can satisfy the needs by adding servers, without affecting the existing services and reducing service quality. Load balancing also has high reliability. When a server fails, the LB application or LB device redistributes user requests to other servers in the same cluster, ensuring uninterrupted services.

Abstract

The increasing demand for the utilize services computer networks has increased the traffic on the network. In general, the server provides service round the clock without a break, so that problems such as breakdown of communication in the network is lost that must be avoided. This cases need for a bettersystem with high performance and reliable every time. Current server technology development will be fast but the memory access speed is slower than the increase in the consumption of bandwidth. This is one o f the factors causing the bottleneck experienced of server. With the load balancing can be provide abetter solution. The concept used to provide a server has the same service. Then, the load balancing will check the CPU usage on each server. The server will perform selection based on the value of the smallest CPU Usage o f all existing servers. The application load balancing is placed before the user accessing ofserver with the object of distributing requests from the user to any of the servers that have been selected by the load balancer. Load balancing provides many benefits to systems that use it. The first, low cost, existing resources do not need to be replaced or discarded. Second, don't always need high end equipment. Third, easily developed when needed arose and a drastic decline in the quality o f service. Load balancing is also more secure, when a failure occurs on the server, load balancing application will redirect the user to the server is still available.
