Top Ten Reasons To Run Load and Performance Testing In The Cloud

Once the functional testing phase is done, it's time for the fun of performance testing. And here you have a major decision. Paper or plastic? No, not that question, but close.

Both questions offer an environmentally friendly option though. Your question is-


Do I create my own testing lab for running performance tests or do I opt for cloud-based services?

To help you make the your decision, we've compiled this nifty list of the benefits of using testing in cloud.

1.Realistic Load

Imagine that you are testing a car. You can open and close doors, accelerate and jam on the brakes....turn the radio off and on, beep the horn incessantly to annoy the garage staff, etc. You can 'test' all these actions while the car is actually situated on the garage lift. That is what performance testing behind corporation firewall is like. No third-side traffic, no disconnection, no DNS errors. In other words, ideal conditions, which you will never get after deploying your application onto a live production server.

How can you trust those types of results? You can't. There are other values of response time, throughput, all sort of errors that happen on a live production server. And cloud testing services allow you to test your all important applications under these real-life conditions. Cloud testing makes use of cloud-computing resources in order to simulate real users who come directly from the Internet.

In the Global Network there are many factors that affect your web-application performance in a load scenario. These are not included while testing within the corporate LAN. The  disadvantage of such load testing is that there is no reflection of the system performance under load, as in real-world load scenarios.

2.Saving $$$ By NOT Buying Hardware or Larger Office Space

Obviously, if you start using testing in cloud services, you save money and large amounts of time. How? Well, how about:

  • You do not need to buy hardware for the new testing lab.

     Just continue using the same hardware you have and pay for service.

  • You won't have to hire support engineers for the new testing lab.

    No need to apply for additional efforts from the HR managers. They love that.

  • No need to support software for the testing lab.

     How much money do you normally have to pay for using commercial tools in your testing lab? Paying for a service could prove more viable for your overall core business.

3.Saving Time

How much effort and time do you spend updating software? In cloud testing, it's the job of the service provider, not yours. Whohoo!


By using SaaS for load testing, you won't be tied to certain software because you can switch to another vendor anytime. No cancellation fees. Service providers thus provide excellent customer service to make sure you are happy.

Moreover, you can cancel your services with the vendor automatically. No need to go through a long process via the technical support of the SaaS vendor.

Using cloud for testing allows you to run tests from anywhere you have an Internet connection and a browser. This will enable greater flexibility in work schedules and potentially reduce the stress on the fact that there is always the chance that the internal testing lab might break down. This helps ensure testing  schedules remain intact.

As a result, you increase your chances of the releases going out on time for YOUR clients.

5.Degree of Service

Another key factor is the degree of service that can be provided by a SaaS vendor. SaaS vendors can offer a higher level of service in comparison with your internal IT department. This is especially true in cases where the SaaS vendor uses an SLA contract.

6.Software Licensing & Customer Support

A key element that explains the economic feasibility of using SaaS is the effect of scaling. SaaS vendors support common software cores that are shared between all customers. That's why fewer resources are depleted in comparison to the classic model where each customer uses a separate distribution of software. Ultimately, the cost of testing for the end customer become less than the cost of testing in an internal testing lab.

7.Focusing On Performance Testing

Performance analysts work many, many hours to support testing environments. The salary for a qualified performance tester is very high as a good analyst can earn as much as developer. And rightly so as performance analysts must be masters of varying technologies and be fluent in two+ programming languages. Using such a valuable resource for installing and supporting software is a bit wasteful, no?

8.High Scalability

What will you do if you need to increase amount of users for testing from 1,000 to 20,000? And then reducing back to 1,000 users? How many servers should you have? And how many servers will be idle during these scenarios? Isn't it better to use these resources for the purpose of actual performance testing and simply select the amount of services you want on an on-demand basis?

Oh and “Yes” - is the only acceptable answer.

9.Your Load Testing Will Go On.

If you move the testing environment to a cloud service, then you alleviate the concenr of power outages, hardware failures or other facility disasters at the office.

10.No Geographical Barriers

You can hire performance specialists from any country you want at varying rates, and there will be no problem with sharing the testing environment. All you (and they) need is a stable Internet connection.
