Comparing Public Cloud Performance – Part Three – GCP

In the first series on this post I looked at Azure VMs and provided a comparison with IONOS Enterprise Cloud, in the second part we looked at AWS, this final post of the series will look at comparing Google Cloud Platform (GCP).

As a bit of background in case you haven’t read the first or second parts yet, I’ve been working with the major cloud vendors for some years now and for me performance has always been a key factor when choosing the right platform, I’ve always struggled in finding the right balance of cost vs performance when choosing the right platforms and have created this blog to highlight some of the differences.

I’ve just started a new role as Cloud Architect for 1&1 IONOS Enterprise cloud and one of the main factors in coming here was the technology and some of the claims that it makes especially with performance and simplicity. This blog will highlight those performance claims and also the cost benefit that choosing the right cloud provider will be for you.

For these tests I’ve kept it simple, I’m using small instances that will host microservices so cost is one variable but performance is another, I will be creating an instance with 1 vCPU and 2Gb RAM, this system will be a base line for testing and I will use Novabench ( for some basic CPU and RAM performance modelling. There are so many tools out there but I find this one real quick and simple to test against some key attributes I will also be using the same tool for the instances so not unbiased results too.

So on with the comparison and next up is GCP for this I’ve selected a custom VM size as this is as near as consistent with other instances on the clouds I have been testing, The CPU used is an Intel Xeon 2.3Ghz and the price for this including windows server licensing and support costs comes out at £50.64 per month

For IONOS Enterprise Cloud I’ve also selected a similar spec as GCP which is a 1 CPU and 2Gb RAM and have used the Intel Haswell E5-2660v3 based chip for the OS as this will be as close to the custom VM in GCP, Like GCP I’ve also included the Windows Server license cost in the subscription along with 24/7 support which is actually free. The monthly cost for this server is £59.18 so comparing costs of using IONOS Enterprise Cloud there is a slight benefit of using GCP as you would save £102.48 over the year, so looks like GCP has a cost edge over IONOS, so what about the performance.

First I wanted to see how the external and internal internet connectivity was performing, to no big surprise IONOS way out performed Azure by a factor of 2, which is to be expected given the infrastructure back end design running on InfiniBand and the datacentre interconnects. The download speed was comparable for Google which you would expect from the internet giant.

Next the focus turned to CPU, RAM and disk performance for this I ran the Novabench performance utility and performed tests on both servers, the tests did throw up some major differences between the two. Let’s take a look at GCP first

The GCP results were interesting to a point that twice as much resources are to be required to get to the same level of the IONOS instance.The GCP instance had a more or less half that of a score for its CPU, RAM and Disk benchmark compared to IONOS but it must be noted that the GCP resources are shared resources instances being hosted on GCP, the RAM score was also at a much lower throughput with a difference of 11964 MB/s, but what was noticeable was that the disk read and write performance was half that of IONOS. the write speed was not what would be expected from SSD storage.

The IONOS Enterprise cloud exhibited near twice the values from the results to GCP.

Due to the dedicated resources that are used by IONOS Enterprise Cloud it becomes apparent that other Public Cloud vendors have to double (GCP & AWS) or even quadruple (Azure) their resource configurations to be comparable in performance to IONOS. Comparing GCP to IONOS to catch up to a similar performance of that of IONOS Enterprise Cloud the GCP instance would need to be reconfigured to a custom VM with 2 vCPUs and 4Gb RAM size this is 2 times the resources of the IONOS Instance which would increase the monthly cost to £94.57 which would equate to £1134.84 for the year of which you would have to pay an extra £423.96 per year for an equal performance instance of that of the IONOS instance.

Can you really justify that type of expense of spending an additional £400 per year for just one system for the same performance? IONOS Enterprise Cloud provides dedicated CPU and Memory and is surely the way to go.

Don’t just take my word for it, give it a go yourself, I’m sure you’ll be impressed with the results.
