Clouds comparison in December 2018

Google remains in first place in the CloudScreener / Cedexis / JDN comparison. Moving up four positions, IBM ranks just behind.

On November 2015, Google remains at the top of the CloudScreener / Cedexis Cloud Cloud monthly comparison for the JDN. A position that the American group still owes, in particular, to its number one position in terms of tariff offer. Progressing four positions compared to October, IBM  Softlayer ranks just behind. IBM’s cloud is benefiting from a significantly improved level of performance, but also from an increased level of service.

Other progress this month, Microsoft goes from 9th to 7th place, and this in particular new instances (Dv2) more powerful than the family previously taken into account (D / DS). “This range of virtual machines in the Azure North Europe data center , which is cheaper than Western Europe, is the most interesting choice in the Microsoft range for French users,” said Anthony Sollinger. , co-founder and president of CloudScreener. Azure is near Amazon Web Services in the overall standings. 

OVH, whose cloud offering was launched in final version this summer, is still being integrated in the ranking. It should appear soon.

Cloud: Comparative Service Levels

IBM’s cloud is gaining momentum in terms of certification in November. Softlayer has won SOC1 and ISO 27018. “He now has all SOC and ISO certifications,” notes Anthony Sollinger. A level of standardization that allows him to see his index of service levels increased by 10 points. In the end, Softlayer moves from the third to the second position in the category. “IBM has also posted a self-assessment of its Softlayer services to the Cloud Security Alliance (CSA), which is the first significant step before CSA certification,” notes Anthony Sollinger.

Microsoft, too, manages to advance its service level index (it increases by no less than 6 points). A rise that the publisher owes to the launch of its G instances, now available in Western Europe, and the resulting expansion in terms of VM range within its offering. This gain allows him to follow IBM in this category.

Notes: SoftLayer offers up to 16-core (non-vCPU) VMs and 64 GB RAM, and bare metal solutions up to 40 cores and 512 GB RAM. It displays a 100% availability commitment on the administration portal and the network, with customer credit for any interruption beyond 30 consecutive minutes (ie 99.93%). But it does not offer a commitment on the compute part (VM), but a 2-hour recovery guarantee on the underlying hardware (99.73% mensupas el, ignoring the restoration of the upper layers) . Numergy offers a commitment of 99.9% uptime and 99.99% through its reseller partners.

Cloud: comparative performance

Despite a decline in its disk and RAM performance, Ikoula remains at the top of the Cloud performance comparison. Among the great advances in this category, Microsoft Azure records an index up nearly 20 points, It takes advantage of the introduction of Dv2 instances. “Their performance is in the order of 30 to 40% higher than that of the D / DS family,” it is estimated at CloudScreener. For its part, Rackspace moved from eighth to sixth place (with an index up 20 points) thanks to the improvement of its indicators in terms of disk and RAM.

In seventh place in October, Softlayer took fourth place in November in this category of performances (+15 points). It benefits from a much better performance in RAM. 

Measures ** CloudScreener Measures


  • Response time: median response time in milliseconds (measured by Cedexis for all ISPs from France)
  • Availability rate: median percentage availability rate (measured by Cedexis for all ISPs from France)
  • IOPS: average number of input-output operations per second (100% random write 4KB test)
  • Bandwidth: average bandwidth in megabytes per second (100% 1MB sequential write test)
  • CPU / Events / sec: average number of events processed per second (from 32 processes started every 60 seconds with the SysBench tool)
  • RAM / Transfer Speed: average transfer rate in megabytes per second

Cloud: price comparison

The Azure instances of the Microsoft North European Data Center are now included in this Cloud Cloud Comparison Cloud / Cedexis / JDN. They are about 13% cheaper than those of the Western Europe data center of the American group. This change allows Microsoft to advance two positions in the price category of the ranking, and move ahead of IBM and Amazon in this area.

“The euro-dollar exchange rate is slightly penalizing suppliers whose price grid is in dollars only,” adds Anthony Sollinger at CloudScreener.

Methodology  : The CloudScreener / Cedexis / JDN ranking is developed using a CloudScreener Performance / Price / Service Level monitoring platform and Cedexis’ network monitoring infrastructure.

The price indexes on which the ranking is based are calculated from several indicators: the price of standard instances, and cloudconfigurations adapted to three business project perimeters. As for the performance indices, they include performance indicators (IOPS, RAM, CPU …), derived from the CloudScreener supervision system, and Cedexis network performance indicators.
