Have you ever visited your favorite website, only to find that it was down? If so, you surely understand the importance of website uptime. In this article, we will examine four of the most important principles of successfully maintaining website uptime, namely: uptime monitoring, data backups, data redundancy, and failover.
Why is Uptime so Important?
Server and Application monitoring proactively track website and server health (such as HTTP, Memory, Disk, CPU, Network, and Load Time), alerting you in case of any critical failure so that you can react as fast as possible.
Monitoring domain expiration, blacklist status, malware detection, and many other custom checks expand the capabilities of performance indicators. It also allows you to regularly review your monitoring data, be able to detect long-time trends, and continuously improve websites performance.
As part of uptime management, it is important to integrate a tiered support structure into the 24/7 Network Operation Center (NOC) service by detecting, prioritizing, escalating, and immediately and efficiently resolving incidents. This helps optimize the cloud-based IT operation, tackle system downtime and, ultimately, guarantee operational peace of mind.
Backups are very important to ensure that your website maintains consistent operations. If something goes wrong, your data has been corrupted, or an upgrade does not go smoothly, a data backup will allow you to get your website back online quickly.
One way to increase backup reliability is to combine redundancy into your backup solution. Data redundancy will copy your website data over to a backup server, which is designed to come online if a production server fails. Therefore, when a production server goes down, a different (backup) one can temporarily pick up the slack. The backup server is constantly synchronized and is provisioned to take over the primary production server at any time.
Based on data redundancy implementation, automatic DNS failover and monitoring solutions can guarantee that as soon as a website goes down, all traffic will be automatically pointed to a backup server. Once the solution detects that the primary production server is running again, traffic will then automatically be diverted back there. DNS failover is able to provide an effective primary defense solution against downtime caused by infrastructure failures.
It's clear that if your website is down, it will have detrimental effects on your business, your traffic, and your reputation. Thus, measures should be taken to ensure as little website downtime as possible. As illustrated above, following the four primary principles elaborated upon will serve you well in this respect.
