In reality, writing web application should be considered as a straightforward experience. This should be quite easy to do if we have more than enough expertise in server-side scripting. We should also be experienced in database system. Website development should cater to many users and this will require many sets of tricks. We should take many factors into careful consideration. As an example, server resources could be utilized with optimal coding practices. In fact, it is possible that we are required to store and retrieve information on a massive scale. So, instead of relying only on a single web server, our online application could work on multiple servers. There could also be variable configurations that we need. Our programming system should be able distributing content and processing works across different servers. When CPU load utilizations have gone really high, we should be aware that more servers will be required. The web server will take more time to respond to user requests and things will take much longer to complete.
The number of visits will increase if we need to take into consideration sorting of huge records, real time image manipulation and video conversion process. This could happen when we allow users to upload their multimedia content, so they could share it to their friends and relatives. People would use content with different sizes and formats, requiring our system to make adjustments and this will require plenty of server resources. One of the more important strategies is to separate our actual web hosting with the servers for applications. In this case, data will be processed in different servers and then integrated inside the web hosting servers and send to readers. This will require more complex implementation. As an example, we may need to store session information on separate folders, such as /tmp. In this case, we will need to utilize a common database with session handler. This strategy may require us to utilize shared files that are placed in common areas. In this case, multiple users should be present in multiple servers, so workload can be shared effectively.
In this case, we will need local network connections to establish our database backend. It is important because, web servers can be accessed with common data pool without any kind of complexity. It means that bottlenecks in database storage can be removed effectively. We need a highly reliable system, if a huge amount of data will need to be stored in thousands or even millions of rows. Without efficient structure, we will get heavy server usages with fewer results. There should be highly matching database indexes that will ensure instantaneous retrievals of data. In this case, we are discussing more about scalability and it is important for us to have more solid plans. We may also need to split different data partitions into many different servers. Another thing that we need to do is to replicate the database in real time, so they can be processed continuously and concurrently.
