Strategy for Performance Testing in the Cloud
2
Introduction Cloud computing is changing the
way applications are deployed, monitored, and
used by the endusers. Cloud offers a
virtuallyinfinite pool of resources for
computing, storage, and networking resources
where applications can be scaled as desired. But
it is important to measure the performance of
these applications in the cloud. Performance is
the utmost factor in testing a web application as
it directly impacts the enduser
experience.    However, Performance testing
in the cloud is different from that of
traditional applications. The main aim of
Performance testing is to measure the parameters
such as system throughput  latency with changing
number of parallel users accessing your
application, with different load profiles, and
various other performance metrics. In Cloud
infra, this becomes a bit more typical with
various virtual machines coming into play.

Understanding the cloud  Cloud is a pay-per-use
kind of model which you can scale whenever you
want. You can demand the additional resources
required and it will be allocated to you. With a
high degree of location independence, virtual
resources are dynamically assigned and reassigned
according to the customers needs.  Some of the
metrics which are important for a
successful cloud implementation are storage,
processing, bandwidth, and the number of users
accessing it at any given point. Elasticity is
one of the major factors for the cloud
infrastructure as it defines the clouds ability
to deal with varying load variations by adding
more resources during high load or consolidating
the users to fewer points when the load
decreases, all in a live cloud setup.
Scalability, availability, fault tolerance, and
reliability are other factors that define a good
cloud infrastructure. Moving performance and
loadbased application testing to the cloud
lowers capital and operational costs
and offers support for distributed development

• Cloud-based testing allows you to get the
  maximum performance by utilizing a cost-effective
  means of testing applications at scale. It also
  allows you to simulate load tests constituting
  millions of concurrent users coming from multiple
  geographical locations.

• Below are the types of performance tests
  you should conduct 
• Stress test Stress testing validates the
  responsiveness, reliability, and stability of the
  cloud infrastructure under extremely high load. 
• Load test Load testing ascertains whether or not
  the system performs optimally when it is being
  used by multiple users at the same time. 
• Browser testing This type of testing is critical
  for determining the compatibility of a browser
  with the overall system.
