Senior Manager - Performance Architect at a computer software company with 10,001+ employees

Is user-friendly and offers live monitoring

Extending the same cloud tool to make it app native so that it can help with device performance testing towards HTTP requests and responses. If you can have a front-end tool like Google's Core Web Vitals, it would be great. If you have some integration with Google's Core Web Vitals, it would be great. I want the tool to have IP spoofing because whenever you do load testing, you will have a little bit of static IP based on a particular load generator. If we have an option of just making the real-time scenario, like having IP spoofing, and the range of IPs dynamically gets changed with the request just to mimic the real-time user behavior, then it would be a good improvement. Having integration to APM tools, like Dynatrace or AppDynamics, the way we have in the load tools, would be good.

Lighter on the RAM and has native Grafana support

The tool's big advantage is that it is more performance-test oriented for experienced testers who know what they are doing. In a normal working setup, performance engineers frequently work with DevOps and development teams. For these teams, k6 Open Source's syntax is much simpler and easier to understand and apply in the working process. Recently, I had a case where I was using another tool, and there wasn't enough memory for it because it required more RAM. k6 Open Source, on the other hand, is lighter and doesn't have a UI, which is beneficial. An engineer I was training could use k6 Open Source scripts even without my help. The tool is more efficient and has native support with Grafana, as both are developed by the same company. This integration enhances monitoring and loss ratio tracking. Thanks to its intelligent GUI, k6 Open Source's design is simpler, particularly for complex scenarios. When we need to manage hundreds of thousands or millions of transactions per minute, the solution becomes a game-changer compared to JMeter.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The level of support is quite good and the integration is also very flexible."

"Soasta CloudTest is an integral part of our performance testing strategy and key in generating load across geography."

"The solution is very stable."

"The solution was easy to set-up and much more easy and intuitive to build performance tests."

"Akamai Cloud Test provides detailed analysis during load and performance testing which helps in determining different components of our platforms and external integrations with other vendors needs optimization (i.e.) it highlights exact API call with request, response, error, TTFB to identify root cause of failure which in turn helps in improving time to resolution and prioritize change requests."

"The agents on the cloud have been extremely valuable for us."

"Customer service is great; quick to act on everything."

"From my own experience, if you're talking about load testing and performance testing then definitely you should go for CloudTest. Because when we compared CloudTest with Performance Center, cost wise it was a better solution. It is easy to use as well, and you can definitely get an automation engineer or a performance engineer with very little exposure to any programming or scripting language such as JavaScript. I would definitely recommend this solution and would rate it at eight on a scale from one to ten."

"The tool's big advantage is that it is more performance-test oriented for experienced testers who know what they are doing. In a normal working setup, performance engineers frequently work with DevOps and development teams. For these teams, k6 Open Source's syntax is much simpler and easier to understand and apply in the working process."

"The standout feature of k6 is its strong focus on API performance testing."

Cons

"Akamai CloudTest integration into our current CI/CD pipelines identify and resolve the issues during the sprint phase which helps in delivering an absolute product and reduces time to market and release."

"If we have an option of just making the real-time scenario, like having IP spoofing, and the range of IPs dynamically gets changed with the request just to mimic the real-time user behavior, then it would be a good improvement."

"The test clip should be more user-friendly."

"I couldn't say, as I haven't used it outside the training or applied it to any project yet."

"Akamai cloud test integration into our current CI/CD pipelines (i.e.) identify and resolve the issues during the sprint phase which helps in delivering an absolute product and reduces time to market/release."

"In terms of improvement, I think integration of these tools with the leading EPM tools would be good. It would help to seamlessly integrate to Dynatrace or AppDynamics to understand what the profiling looks like when generating a load."

"Out of five, I would rate the technical support of the solution at two or three. Sometimes it's a challenge because we face delays."

"It's a manual process to whitelist respective internal IPs in coordination with web operations team to access Soasta. Availability of any standardized tool from Soasta will make setup process easy."

More Akamai CloudTest cons

"One area where k6 could improve is by introducing a GUI similar to JMeter."

Pricing and Cost Advice

"We have a yearly license, and I would give it a rating of three out of five."

"Running cost is very low."

"The tool's price is at an intermediate level. When you compare it with other enterprise load testing tools, it falls under the average category."
