Implementasi Server Cluster High Availability Pada Web Server Dengan Sistem Operasi Turnkey Linux Menggunakan Heartbeat

  When this information is a very important requirement for the community. Information required to be kept up to date so that the necessary means in the form of servers that are able to provide services without having problems. Computer cluster is a technology that utilizes multiple single computer resources which then work together so that it looks like one integrated system. This research aims to implement a failover cluster system as a solution to overcome the failure of server functionality by using Turnkey Linux as its platform. Failover clusters are built consists of two servers with the Linux operating system Turnkey 14.00. Both application server installed heartbeat that serves to connect both servers and applications functioning DRBD for data synchronization. Server cluster that has been designed to work well so as to increase the availability of stable services on the web server because the server is currently experiencing damage to hardware or software, the backup server will be automatically converted to the primary server for the primary server down. With a failover cluster system that has been implemented proven to guarantee the availability of the service on a web server that implements the server cluster.   Keyword : cluster computer, DRBD, failover cluster, server, server cluster. &nbsp

Penerapan Teknik Load Balancing pada Web Server Lokal dengan Metode Nth Menggunakan Mikrotik

  The development of web technologies lead to servers that provide network-based services on the local as well as the public should be able to cope with the demand and greater workloads than ever. To be able to meet the demands of the development of the web technology required load balancing technology. Load balancing role in dividing the burden on services either on a set of servers or network devices. In this research is implemented using the method of load balancing technology Nth on the router mikrotik by dividing two line interfaces. The test results indicate the existence of a balance of access at the time of the file from the web server on each client with the bandwidth that has been adapted by tital download speed on a client of 68 Kbps in accordance with predeterminded bandwidth that is 512 kbps.   Keyword : Bandwidth, Load balancing, Mikrotik, Nth, Web Server. &nbsp

Aplikasi Manajemen Bandwidth pada Usb Tethering Android Menggunakan Mikrotik

  The rise of smartphone technology develops, the number of requests made easy internet access. One of the burgeoning smartphone is Android smartphone. Android has given the ease of access to the internet with their facilities, one of which is USB Tethering.USB tethering is a feature that has been provided by the Android smartphone is still little use. The purpose of this study is to optimize the existing USB tethering on a smartphone using Hierarchical Tocken Bucket with simple techniques queue into a modem capable of transmitting data packets to multiple client and apply bandwidth management to every client. The results of this study are in the form of restrictions on each client with customized bandwidth from the provider that has been determined. The test results of the speed test can be seen that the results are in accordance with the allocation for each individual client so that there is inequality between the client.   Keyword : Hierarchical Tocken  Bucket, Manajemen Bandwidth, Mikrotik, Simple Queue.   &nbsp
