Today no less than 60% of companies are either exploring the possibilities of adopting artificial intelligence or trying to realize its potential to transform the way they do business. The problem is that a significant portion of them (one-third) struggle to produce substantial change with AI.

The lifecycle of an AI solution usually consists of problem definition, data collection, model building, model fine-tuning, and applying the solution to solve a specific problem. Various experts build the solution to solve business problems. Still, a problem solved by a data scientist does not automatically translate into a constant stream of actual value for the business. Once deployed to production, the AI solution cannot be left as-is. Like any other system, it requires continuous maintenance. However, any AI solution’s maintenance differs significantly from the maintenance of other systems (e.g., microservice-based applications). The performance of any AI solution can be affected by many factors, and if the maintenance work is not done, the solution will cause problems instead of solving them.

As more and more organizations making the shift to cloud-native technologies, Kubernetes has become the de facto choice to orchestrate container-based applications. As applications grow in size, the number of microservices increases and so does the data they process. Hence, handling data, especially sensitive data becomes critical. Out of the box, Kubernetes supports « Secrets » objects to store sensitive information — like passwords, tokens, ssh keys, and so on — securely.

Kubernetes secret eliminates the need to hard-code sensitive data in the application code. Secrets provide this sensitive information as data mount or expose them as environment variables.

An unreliable, semi-broken and unresponsive website is an excellent way to lose leads and visitors — regardless of how aesthetically pleasing or well-designed, the visual elements are.

Over the past decade, we’ve seen more initiative to deliver faster internet to regions of the world that were previously devoid of it. With online communities expanding and more people becoming receptive to online shopping, ensuring your site’s dependability is now more important than ever. 

One way to achieve this is by employing uptime and downtime monitoring tools. This guide will examine the best ways to get alerts when something goes wrong and your website falters.

Why Is Website Uptime Monitoring Important?

Downtime is bound to occur occasionally. Nonetheless, the goal is to minimize it. The longer the downtime occurs, the more traffic and potential clients you lose. A dysfunctional website is also detrimental to your credibility and reputation. People may associate your website’s unreliability with your real-world products or services.

With web developers charging an average of $200 per hour, high-quality websites can be expensive to build and maintain. Nevertheless, it’s often worth the investment. However, an unreliable website can backfire on you. Instead of attracting more customers, it could potentially repel them. This can result in lost revenue.

An uptime monitoring solution can help you prevent or reduce these losses. It verifies if your website is up and functional and notifies you if it’s not. This allows you to troubleshoot the issue and get your website back up and running as soon as you’re alerted. The most common issues behind your website’s downtime include: 

  • Server faults;
  • Network outages;
  • Power outage;
  • Traffic spikes;
  • Cyberattacks;
  • Domain name issues;
  • An erroneous web application deployment;
  • Increased server loads;
  • DNS Resolve issues;
  • Human error.

Thus, you must employ a dependable tool that detects downtime or any interruptions related to your website as soon as they occur. They are must-have tools for web designers, developers, and network administrators. However, not all of them are built the same. So how do you identify the best uptime monitoring tools?

Essential Features of Uptime Monitoring Tools

Uptime monitoring tools typically detect interruptions by running network tests such as pings and trace routes. You could practically monitor your website’s uptime by constantly running these tests yourself. 

However, this isn’t an efficient way to monitor your website’s uptime. A comprehensive uptime monitoring tool will automatically monitor your website’s uptime in the background. It will then alert you through various channels as soon as it senses that your website may be down. 

Furthermore, high-quality uptime monitoring solutions tend to offer additional information regarding your website’s uptime/downtime and its performance. These tools commonly feature dashboards, status pages, badges, exportable records, etc., to help you keep track of your site’s overall health.

9 Best Features of an Uptime Monitoring Solution

The ideal uptime monitoring tool or service should feature: 

  1. Website security features that notify of and repel potential cyber attacks;
  2. 24/7 uninterrupted background website monitoring;
  3. Multi-channel alerts (email, SMS, push notifications, instant messages, social media, etc.);
  4. Report generation;
  5. 24/7 customer support available through different channels (email, phone, chat, etc.);
  6. Be capable of monitoring multiple websites and proxies at the same time;
  7. Offer insights and suggestions to improve your website’s performance;
  8. Be affordable;
  9. High customizability should allow you to choose which features to enable and disable.

Another optional feature to look out for is public status pages that your clients can access to determine if all your services are up and running. GetWeave is an excellent example of this. The website features a well-organized systems status page where customers can check if all of Weave’s services are functional. 

Nevertheless, you can use the above information as a buying guide when assessing potential uptime monitoring tools. The rest of this guide will supply a few suggestions as to which tools you should use for your website.

Perimeter security has been dying a slow death over the better part of a decade, as breaches of the corporate network have become commonplace. Most organizations now find it obvious that trusting devices and users merely for being « on the corpnet » is insufficient to maintain security in the face of evolving threats.

At the same time, the re-platforming of business applications to a SaaS model, coupled with a more mobile and distributed workforce, has made the need to « VPN into a corpnet » feel archaic and cumbersome. The pandemic created the perfect storm around these two long-term trends, accelerating this slow death into a fast one. Adopting a zero-trust architecture is no longer negotiable for any organization that wants to stay alive.
