What and Why of moving from Performance
Testing to Performance Engineering
Global enterprises and brands have been working
towards ensuring performance and functional
excellence for their digital propositions.
Implementing a robust Performance Testing
strategy has been a conscious and strategic
decision for all kinds of enterprises operating
across diverse businesses. Today, validating and
ensuring the speed, stability, and responsiveness
of an application is absolutely business
critical. Various facets of Performance Testing
have been adopted for the same, confirming that
the application doesnt vacillate under
unforeseen conditions. However, there has been a
shift in conceptual thinking, where the attention
has shifted more towards Performance Engineering,
from Performance Testing. Performance
Engineering refers to the techniques that are
being applied in the development lifecycle, which
ensure the non-functional requirements for
performance. Some of the key requirements are
ensuring throughput, latency, and usage of the
memory. These features are needed to confirm and
assess that the systems are user-friendly,
secure, and scalable over even in the longer run.
As recommended, Application Performance
Engineering is a much needed practice for DevOps
and Agile teams to validate efficiency of the
applications. The ultimate objective is to
derive better business value for the organization
through the overall development cycle. Moreover,
it also ensures that the unforeseen cost of
fixing a bug is not incurred towards the end.

What and Why of moving from Performance
Testing to Performance Engineering
Growing Significance of Performance
Engineering The rising recognition for
Performance Engineering is due to the growing
complications with new-age applications and the
emerging technologies that are creating these
multiple layers. Most of the applications today
engage with multiple third-party vendors and
parties to drive growth and innovation for the
customers. Hence, it is no more a single activity
driven growth, it just gets more and more
complicated. Any new feature and technology has
to be built over the legacy system, which becomes
a support system for the application. Hence,
testing the application against these legacy
systems becomes indispensable. These legacy
systems have to be tested, as they need to meet
the current performance parameters. It is highly
critical to avoid any hiccups with the
performance and stay prepared for any unforeseen
circumstances. This needs Performance Engineering
mind-set rather than a Performance Testing
approach. Performance engineering approach is
needed to not only ensure flawless performance,
but also to enable rapid application delivery.
Today, enterprises and businesses need rapid
turnaround and no delay in time to market. This
can be made possible only when performance
testing is engineered within the application
development cycle. There is no chance that they
can wait till the last moment to realize the
issue and rectify it towards the end. Performance
Engineering enables you to get it right the first
time.

Testing to Performance Engineering

Within the Agile process, Performance Engineering
methodologies can be effectively aligned with the
shift-left approach. This helps to address the
performance issues way ahead in the development
process. In this way, performance bottlenecks can
be identified and reasons can also be found out
too. Moreover, the overall system performance can
be optimized in this process. A well
thought-through Performance Engineering and
Testing strategy can enable teams to deal with
the challenges that are being posed by
inadequately performing applications. It helps in
benchmarking the performance of the application
and ultimately evaluating against business
critical scenarios for effective performance
testing. The digital sphere has innumerable
aspects that keep challenging the applications
flawless functioning and expected performance
parameters. Read Full Blog at
