Cedexis helps admins fight performance anxiety

And shop for cloudy infrastructure

If you are shopping around for cloudy infrastructure or content delivery network providers, you probably experience a certain amount of performance anxiety while you're haggling. Even if you get a good price for compute, storage, or network capacity, you can't know how various services are performing until you have made your commitments... unless you use the tools developed by Cedexis, which has just put out a freebie portal into the data it gathers every day about the performance of the major ISPs, clouds, and CDNs.

Cedexis is no more altruistic than any other software company in the world, but uses its freebie portals as a means of promoting its community-based Radar web-page tagging service, which gathers up data from all over the world and makes it accessible in real time to the Openmix traffic management software. The idea is simple: Let Cedexis tag your pages with some JavaScript (which doesn't execute until after your pages fully load) and you get to see your application performance data from your end users' perspective, which helps you run your business better. Cedexis then aggregates all of the data – which is stripped down and anonymised – from its community of users (over 32,000 networks are contributing data), and uses this firehose of performance information as telemetry for the Openmix tool, which helps companies with apps scattered around the globe avoid traffic jams and slowdowns on cloudy infrastructure.

Some companies are hesitant about tweaking their web pages with someone else's code, but Cedexis needs to show them that the data it is gathering is useful. And for that reason Cedexis has just put out a new portal called Free Country Reports that gives you real-time data about the performance of ISPs, cloud providers, and CDNs, adding in some stats that show the performance of customers who are optimizing their traffic across multiple clouds using the Openmix tool.

Here's what the cloud performance data for users in the United States looked like as El Reg was going to press with this story:

It's no surprise that the multi-cloud optimized performance for users based in the United States is two, three, or four times better than for raw cloudy capacity feeding users from the UK, Europe, and Asia. You will have to just see for yourself how important a few hundred milliseconds difference is. But page rankings on Google are at least partly based on how responsive your application is, so it isn't like it doesn't matter to most of the world in one way or another.

Here's what the error rate among global cloudy infrastructure providers feeding users in the United States looked like:

In general, the further you get away, the higher the error rates. The optimized clouds using the Openmix tool, shown on the top of the data, had such a low error rate that you can't even see it on the chart.

The ISP data that Cedexis is putting out through the country portal is based on information culled from 4,140 ISPs and has nearly 39 million total measurements. To come up with the ISP, cloud, and CDN data, the Radar tags read two different objects, one only 50 bytes and the other weighing in at 100KB. You can see the company's measurement methodology here, and you can see the latest data for Great Britain there. There is also a freebie Radar performance dashboard that you can use to extract trend data out of the Radar data.

The Cedexis freebie traffic data is similar to that which Compuware launched two years ago through its CloudSleuth portal, which is based on the real-world performance of customers using Compuware's Gomez performance management tools. CloudSleuth measures response time and availability for infrastructure and platform clouds as well as CDNs. ®
