amazonsignage2A report from IDC this morning says overall industry revenue from public cloud services — everything from basic storage to software as a service — reached $45.7 billion in 2013. That’s about 2 percent of an estimated $2 trillion in annual IT spending.

It’s a key market to watch as cloud services replace traditional software and servers for many companies. The research firm says cloud services will expand at a compound annual growth rate of 23 percent over the next five years.

So who’s winning? It depends on the category of cloud service, but the report pegs Amazon and Salesforce as the clear leaders, with Google, Rackspace, IBM and Microsoft also in the top 5 in some areas.

Here’s how IDC breaks it down …

Cloud Software: 86% of the overall cloud services market in 2013, consists of Software as a Service and Platform as a Service.

The SaaS category has been mainly driven by enterprise applications solutions, such as enterprise resource management (ERM) and customer relationship management (CRM), followed by collaborative applications. Holding a smaller share of the SaaS category are System Infrastructure Software solutions, such as Security and Storage software. From a competitive perspective, the SaaS service provider ecosystem is largely led by Salesforce.com followed by ADP and Intuit. Traditional software vendors like Oracle and Microsoft hold the 4th and 5th position respectively.

The PaaS market has been largely driven by Integration and Process Automation solutions, Structured Data Management solutions, and Application Server Middleware. The competitive market is led by Amazon.com, followed by Salesforce.com and Microsoft tied for the number 2 position. GXS and Google hold the 4th and 5th positions, respectively.

Cloud Infrastructure: 14% of overall cloud services market in 2013.

The Cloud Infrastructure product group is comprised by only one product category: Infrastructure-as-a-Service (IaaS), which at the same time is comprised by two markets, Server and Basic Storage. The top 5 vendors in this market are Amazon.com, which holds the first position with more than 40% of market share, RackSpace, IBM, CenturyLink, and Microsoft.
