IaaS, SaaS are most mature, established from a competitive landscape perspective, Paas is least evolved
Worldwide platform-as-a-service (PaaS) revenue is on track to reach $1.2 billion in 2012, up from $900 million in 2011. The market will experience consistent growth with worldwide PaaS revenue totaling $1.5 billion in 2013, and growing to $2.9 billion in 2016, according to information technology research and advisory company Gartner Inc.
"Of all the cloud technological aspects, infrastructure-as-a-service (IaaS) and software-as-a-service (SaaS) are the most mature and established from a competitive landscape perspective, while PaaS is the least evolved," said Fabrizio Biscotti, research director at Gartner.
"For this reason, PaaS is where the battle between vendors and products is set to intensify the most. It comes as no surprise that the PaaS competitive landscape is still in flux, with traditional application infrastructure vendors facing competition from new large players moving into the market, and myriad specialized PaaS pure players cutting into their slice of profits."
The category of PaaS includes suites of application infrastructure services such as application platforms-as-a-service (aPaaS) and integration platforms as a service (iPaaS) as well as specialist application infrastructure services such as database platform-as-a-service, business process management platform-as-a-service, messaging-as-a-service and other functional types of middleware offered as a cloud service.
Users may subscribe to a cloud provider's PaaS or may buy a cloud-enabled application infrastructure product and build their own PaaS for private cloud (private PaaS) or public cloud consumption.
The largest segments within the PaaS market are cloud application platform services (aPaaS), accounting for 34.4% of the total PaaS spending in 2012, cloud application life cycle management (ALM) services (almPaaS) at 12%; cloud BPM platform services (bpmPaaS) at 11.6% ; and cloud integration services (iPaaS) at 11.4%. Gartner predicts that the potential spending in PaaS technologies is an average of $360 million per year from 2011 through 2016.
More than 70% of PaaS functionality today can be referenced to an application infrastructure and middleware (AIM) capability, calling for AIM vendors to consider PaaS in their offerings or to have a strategy to address the needs of those clients looking at cloud for future deployments.
Today, the largest AIM vendors have only marginal share of the PaaS market (lead by Microsoft and some IBM acquisitions), and this leaves the door open for more competitive landscape disruption over the next three years since many of the largest enterprise software vendors are on the cusp of entering the PaaS market with their own offerings.
"The fundamental appeal of PaaS is the opportunity for ISVs (independent software vendors) and IT organisations to create new software solutions with minimal capital expense and without the hassle of provisioning and configuring the underlying infrastructure," said Yefim Natis, analyst at Gartner.
"To many SMBs (small or midsize businesses), in addition, PaaS offers the chance to take advantage of some state of the art enabling technologies, they otherwise could not afford. Finally, the popularity of SaaS also drives adoption of PaaS for customization, extension and integration of the cloud-based applications."
Despite the ongoing economic uncertainties, mature economies, which are also the most mature IT markets, such as the US, Western Europe and Japan, are on the forefront of PaaS adoption. PaaS spending globally is relatively small, and it is almost entirely generated by the US, with 42% of the market, followed by Western Europe and mature Asia-Pacific. All mature economies combined, account for almost 90% of worldwide PaaS spending, Gartner said.
