海外TECH	DEV Community	Bench-marking RESTful APIs | Part - II: On the Cloud	https://dev.to/gochronicles/bench-marking-restful-apis-part-ii-on-the-cloud-fd0	Bench marking RESTful APIs Part II On the CloudHave you ever load tested your APIs on the cloud In this post we explore how to load test and benchmark different RESTful framework s performance Recap In our previous post we did some benchmarks of frameworks from different languages Our test hardware server was my Raspberry Pi Model B from it was a good experiment but this time around we needed something more realistic TL DR We used Kubernetes on Cloud Google Cloud Platform gt jump to benchmarks section Let s get back to our story if are following the storyline from the first post Dave went back to his peers to show benchmark results that he had got in the initial tests which he ran on his Raspberry Pi while some of his peers liked the idea and appreciated the outcome some pointed out that they would need the test on real production grade hardware to believe the results Dave went back to his garage to tweak his test bench IntroOur setup is quite straightforward each RESTful service gets the same amount of CPU and memory enforced via ks config The entire setup takes few minutes to initialize thanks to tools like gcloud CLI Terraform amp Pulumi You can get it up and running with the environment without much hassle And if you want to run the benchmark without fancy infra i e without private VPC etc We recommend that you use the CLI wrapper as it is built over gcloud SDK and for the adventurous type we have a slightly more elaborate setup with Terraform GCP amp Pulumi GCP amp Digital Ocean Environment ReviewKubernetes is a planet scale tool that can orchestrate containerized applications and more Checkout our series on Kubernetes it is swell Since we didn t want to scale the application as load increases we have put some limits The config ensures that the deployments stay put and do not auto scale in the Ks cluster The whole point of this exercise is to simulate a prod environment but without auto scaling We then load test and measure performance Quite the step up from the test on Raspberry Pi isn t it It took us a while to figure out the right configuration for the cluster so that you could replicate the tests on your own with the optimal amount of resources The Ks environment can be setup on GCP free tier at the time of writing this article Source code link for this entire project is given the references section Let s review our K️⃣s Config fileDeployment config looks like this apiVersion apps vkind Deploymentmetadata name rest net http golangspec selector matchLabels app rest net http golang template metadata labels app rest net http golang spec containers name rest net http golang image ghcr io gochronicles benchmark rest frameworks rest net http golang latest imagePullPolicy IfNotPresent resources limits memory Gi cpu m ports containerPort Notice that we have allocated memory Gi and CPU m or half vCPU This constraint is given to all frameworks this will ensure that the amount of compute given to each deployment is consistent apiVersion vkind Servicemetadata name rest net http golangspec type LoadBalancer provide public ip to the service selector app rest net http golang ports port targetPort Service config exposes the RESTful apps in the cluster network via Public IP so that our bench marking client can connect and run load simulations Our attack tool for load testingThis time around we decided to play around with different benchmark amp load testing tools Finally we chose Hey Hey is a drop in replacement for ab tool Apache benchmark hey c n lt http ip addr url gt This command will send concurrent amp total k requests to the RESTful API services on the Ks cluster Honorable mentions Locust ️ This was the ideal tool for this test for couple of important reasons We could deploy this python based web app like load test tool on Ks cluster and run benchmarks from with in the cluster network no need for public IP It comes with a nice UI dashboard to visualize the results The test results was same across frameworks it looked like we couldn t schedule enough number of workers to really push the throttle on the RESTful APIs We had a limit on the number of processors we could deploy on our GCP instance free tier has CPU limit for the entire project If you want to tinker with locust here s the ks config we created Apache Benchmark Good old tool we could still probably use but the results were better and faster with hey and it shares the almost similar CLI options CPU monitoring tool htop revealed that ab tool didn t take advantage of all the CPU cores where as hey tool fired up on all CPU cores with same parameters out of the box Benchmarks The order of slowest to fastest framework is as expected in the benchmark results Go frameworks are at a minimum x faster than Node amp Python based frameworks However the interesting bit is FastAPI Python framework isn t too far off from NestJS which is about faster FastAPI Python NestJS Node ExpressJS Node Gin Golang Net http Go std libray Fiber Golang Close thoughts Results are as we anticipated Go based frameworks are at least x faster than Node amp Python based frameworks One thing surprised us and possible areas for more research In our local testing Gin has always performed faster than Net HTTP Golang However in this test it has scored lower The source code for this service and the Kubernetes config can be found here and here respectively Let us know in the comments if you found a better way to do these tests Your feedback and supportmeans a lot do share some loveby sharing our posts on social media and subscribe to our newsletter
