Upgrading your website without disturbing the current load
Being a network and website administrator is a really tough job. The admin has to constantly look for technology upgrades and loopholes in the current setup. Today’s websites are mainly powered by HTML4/HTML5, CSS, PHP and MySQL. HTML (Hyper Text Markup Language) mainly decides the basic structure of the webpage. CSS is used to add designs and color to the webpage. PHP is used for webpage management purposes while all the important data and all services are stored under MySQL. A perfect web designer should have a total knowledge of all the three. All the above discussed points talk about the software part. Software when used by the appropriate hardware can only show positive results. Hardware management includes server management, managing transmission cables, and maintaining site traffic.
Up gradation can take place in two ways –
Software / Webpage Upgrade
Software/Webpage up-gradation Includes data modification and modification of HTML/CSS involved.
This includes server Load enhancement, increasing server capacity, making a dedicated server, modifying transmission lines – like replacing LAN wires by fiber optic cables or replacing a CAT4 cable by the newer CAT5e cable.
Following points show how you can easily upgrade your website without disturbing access or load –
Changing the data base using MySQL
MySQL is basically a tabular structure for storing all the important data and links contained by the website. This means whenever any addition has to made in the content of the website, data has to be added at the MySQL server. No change occurs in the basic webpage structure or any of its embedded styles. Everything remains the same. So when these changes have to be made, the old webpage is kept active with the old data without any problems. After all the data editing job has been done, then the server can be updated and in this way the webpage has been updated without affecting performance.
Using the ‘replica’ power of MySQL
Specific portion of the database is dedicated to create a replica of the old data before any modification is done to the database. If anything wrong happens or programming code error occurs, changes can be reverted back to the old backup so as to keep the server alive and uninterrupted.
Upgrading Server Capacity
Every server has a limitation of a fixed number of users can access it simultaneously. Server throttling starts once user limit exceeds and many people may experience slow access speeds. At this point, if a Network admin decides to increase the server load capacity, he will have to make extensive hardware changes. At this point, many users may experience slower site access. The admin can post an apology in this case by stating that ‘server is under maintenance’.
Hardware up gradation can lead to sites being unavailable for some time but adding content to the existing webpage should not affect traffic. Keeping the server well maintained and optimizing and tuning up the performance is the priority task of all network admins and they should take care of it.
