Implementasi Highly Available Website Dengan Distributed Replicated Block Device
Abstract: As an important IT
infrastructure, website is a system which requires high reliability and
availability levels. Website meets the criteria as a highly available system
because website must provide services to clients in real time, handle a large
amount of data, and not lose data during transaction. A highly available system
must meet the condition of being able to run continuously as well as
guaranteeing consistency on data requests.
This study designed a website with high availability. The approach was
building network cluster with failover and replicated block device functions.
Failover was built to provide service availability, while replicated block
device provides data consistency during failure of service. With failover cluster and replicated block
device approaches, a cluster which is able to handle service failures of web
server and database server on the website.
The result of this study was the services of the website could run well
if there was any failure in node members of the cluster. The system was able to
provide 99,999 (five nines) availability on database server services and 99,98 (three nines) on web server services.
