Modern companies rely on the internet extensively to provide services, make payments, and connect teams. But the internet that is used around the globe is an extremely fragile structure consisting of thousands of interconnected pieces such as domain name servers, CDNs, and cloud hosting platforms.
If just one component of that digital chain breaks down, all digital platforms go down in an instant. Organizations have to go further than internal network monitoring to protect their bottom line and brand and implement internet resiliency within their very core.
In essence, resilience is the structural ability of an organization to ensure four key pillars within its web stack: reachability, availability, reliability, and performance.
As opposed to regular uptime, internet resilience ensures that the application not only stays alive but also runs smoothly and quickly and is accessible no matter what happens to the external infrastructure providers.
The users will be just as quick to abandon an application if it became sluggish because of third-party network outages as if it went down completely.
The best performing enterprise data centers still encounter unforeseen disruptions because of factors beyond their control:
Today’s websites require third-party API, payment gateways, and cloud hosting services. A disruption in any of these services disrupts the end-user experience.
Errors in Border Gateway Protocol may cause wrong routing of global web traffic, which makes the whole platform inaccessible in certain geographical locations.
In case of DNS downtime, end-users will not be able to convert website URLs into IP addresses. To understand why this happens, it’s important to know how DNS works.
Whenever you enter a website address into your browser, the Domain Name System (DNS) acts like the internet’s phonebook, translating the human-readable domain name into the corresponding IP address of the server hosting the website.
If DNS servers become unavailable or fail to respond, browsers cannot locate the correct server, making websites and online services inaccessible even if the hosting infrastructure is still running.
To maintain consistent uptime, the engineering teams have to factor in the possible failure in every aspect of their digital infrastructure:
Multi-CDN and backup DNS services ensure that traffic automatically gets routed to the healthy network once the primary vendor becomes unavailable.
The specific monitoring systems run synthetic tests along the path of end-users from numerous vantage points globally to identify micro outages and routing problems.
The routing protocols enable automatic rerouting of web traffic to the best-performing server paths based on region-wide performance degradations.
Creating a digital strategy entails embracing the fact that there is going to be an occurrence of network downtime. Through resilience in the Internet, businesses will be able to make sure that their digital assets will be ready to face any kind of unexpected outages in the cloud, fiber cuts, and vendor failures.
