The popularity of web-based applications increases every year and consequently, it’s extremely important to provide end-users with high-quality service.

Nowadays, companies run their business-critical processes through Software as a Service (SaaS) products. According to the market research of Finance Online, SaaS solutions adopting is going to increase incredibly (from 38% in 2016 to 78% in 2022). Web-based applications are definitely following the trend of the cloud market – with SaaS responsible for 70% of the cloud market share.

Therefore, it is extremely important to assure the correct development and implementation of SaaS applications, in order to:

  • Optimize employees’ productivity;
  • Avoid slowdowns and operational costs.


From the “user experience” point of view, users expect applications to be fast,easy-to-use and reliable. To guarantee a high level of performance, it is necessary to monitor, measure and analyze applications’ performance. In fact anomalies, issues and slowing downs can affect user satisfaction and business revenue, because those problems can actually jeopardize employees’ work.

The results of these statements are two end-user experience metrics:



Application availability is the extent to which an application is operational, functional and usable for completing or fulfilling a user’s or business’s requirements. This measure is used to analyze an application’s overall performance and determine its operational statistics in relation to its ability to perform as required.

Application availability is usually part of application monitoring and management software. It is used by application administrators to identify an application’s ability to deliver the required functionality. Typically, application availability is measured through application-specific key performance indicators (KPIs). These can include:

  • The overall or timed application uptime and downtime,
  • The number of transactions completed, errors and other availability-related metrics.

Application scalability, reliability, recoverability and fault tolerance may also be considered when weighing application availability.



Next to availability, applications’ responsiveness is just as critical. This performance indicator is actually able to affect users’ productivity. Therefore, it is extremely important to monitor the speed and the responsiveness of business applications across multiple use cases and search engines.
