Microsoft is taking an increasingly competitive stance against larger rival Amazon Web Services (AWS) in the cloud space, rolling out a new cloud service map comparing platform features.

In a recent blog post, Michael Crump, technical product manager for Microsoft Azure, said the map allows for planning a multi-cloud environment or planning for customers looking to migrate (hint, hint) from AWS to Azure.

The “map” is downloadable as a PDF or is available via GitHub. It includes 13 sections for service comparisons, with each section including a Microsoft-penned description of the service.

Microsoft and AWS — along with other cloud providers — offer online price calculators designed to provide guidance on cloud pricing.

AWS remains the cloud heavyweight, with a recent Synergy Research Group report stating AWS controlled 34 percent of the global market share at the end of the second quarter. Microsoft was a distant No. 2 with 11 percent market share, ahead of IBM (8 percent) and Google (5 percent).

The research firm did note that the four largest players managed to maintain or grow their market share during Q2.

“For me the biggest story is that Amazon/AWS is holding on to its market share despite increasingly strong competition from a handful of big and aggressive competitors,” said Synergy analyst John Dinsdale in an email about the results. “Microsoft, Google, and Alibaba are all growing their cloud revenues at impressive rates, but AWS keeps on growing by over 40 percent, per year, despite its huge scale. That is a really difficult feat to pull off.”

Synergy estimated that quarterly cloud infrastructure service revenues reached almost $11 billion in Q2, and continue to grow at over 40 percent per year. This includes infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and hosted private cloud services.

451 Research earlier this year released a report and hosted a webinar on cloud computing prices, with a specific focus on serverless computing. The report noted that while it was difficult to nail down exact costs associated with serverless computing due to disparate pricing structures, it found IBM to be less expensive than rival services from Microsoft, Google, and AWS.

IBM’s cost advantage was on usage, based on tenths of a second, up to around two seconds of total usage per script. Helping to bolster IBM’s value is that the company does not round up usage to the nearest usage marker, which 451 Research found to be in 128 megabyte buckets.

“IBM has a simple model,” said Owen Rogers, research director for 451 Research’s Digital Economics Unit. “For very small duration scripts, it’s pretty much cheapest all the time, or at least in our parameters.”

For longer usage scenarios, 451 Research found Microsoft’s Azure platform could offer a less expensive product. Google and AWS pricing did not factor into the various usage models provided by 451 Research.
