Generally, organizations move towards AWS to furnish their foundation with the capacity to develop and extend their abilities and because they can only pay for the resources they use.

Why APM is Extremely Significant!

We all have faced the problem when the system gets too slow. Have you wondered why this problem occurs? Well, there could be several reasons but one of them is application performance. In today’s time, the term application has become very large and complex. Users using these applications often choose different mediums, as they have separate goals and requirements as per their needs.

This diversity in consumption medium brings complexity in a configuration which is only increasing in today’s time. Application performance means how available your application is for this real-world which brings us to APM. In this blog, first of all, we will discuss, what is APM, why it is needed, and what are the APM tools, which can help us obtain the information and health of the system.
