Global SaaS, PaaS, IaaS and BPaaS Market 2011 and Forecast


Cloud computing includes Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS) and Business Process as a Service (BPaaS). SaaS is the highest level of the cloud and includes actual cloud applications. SaaS segment is the largest segment in the overall Cloud Computing Market. Customer relationship management (CRM), Content, communications and collaboration (CCC) market and Enterprise resource planning (ERP) revenue are the key sub segments respectively. North America, followed by Europe is the key markets for SaaS. Asia Pacific and Latin America are key growth markets too. Adoption is being driven by availability of on demand software, understanding of the model, increasing interest and pressure on IT managers to reduce costs. Data security concerns, outages, lack of understanding of the cloud and infrastructure, and integration with existing infrastructure are concerns. According to Gartner SaaS market is expected to reach $ 21.5 billion in 2015 from $12.1 billion in 2011. IDC estimates it to reach $ 40.5billion in 2014 from $ 21.8 billion in 2011 and Forrester estimates it to reach $78.4 billion from $21.2 billion in 2011. Google, Citrix, Salesforce.com, NetSuite are key players.







PaaS is the middle level and builds upon the IaaS layer and provides an application development platform for the cloud. Gartner says, PaaS products primarily supported application server capability, but the market has expanded to other middleware capabilities as a service, such as integration, process management, and portal and managed file transfers (MFTs). Gartner analysts said PaaS offerings are likely to expand the application integration and middleware (AIM) market by bringing in a new range of organizations that otherwise would have been packaged application and office software users. Vendors in this space include Windows Azure, Heroku and SalesForce’s Force.com. Salesforce.com has the most mature PaaS. According to Gartner PaaS market is expected to reach $ 1.8 billion in 2015 from $707.4 million in 2011. Forester estimates it to reach $9.8 billion in 2015 from $820 million in 2011.


IaaS is the lowest level of the cloud technology stack. It provides operating system support, storage and processing. Vendors in this sector include Google App Engine and of course Amazon’s (news,site) latest whipping boy AWS EC2. Infrastructure-as-a-service (IaaS) will shift from public clouds to virtual private clouds, Forrester Research projects. While adoption remains high, the size of the market will shrink and public cloud services will cost less in the future because the cost of inputs will continue to decline. According to Gartner IaaS market is expected to reach $ 22 billion in 2015 from $5.6 billion in 2011. IDC estimates it to reach $ 15 billion in 2014 from $ 3.4 billion in 2011 and Forrester estimates it to reach $78.4 billion from $21.2 billion in 2011.

BPaaS is even higher up than SaaS and it includes technology, people, process and smart analytics wrapped in a simple "pay-as-you-go" commercial model. It allows companies to minimize or eliminate substantial upfront costs.  BPO outsourcing providers such as India, China and Latin America will likely make a play in this area. Traditional BPO providers are setting up data centers to offer cloud computing services to their clients and Cloud computing inclusive of BPaaS provides a big opportunity for service providers. According to Gartner BPaaS market is expected to reach $ 133.5 billion in 2015 from $71.7 billion in 2011. Forester estimates it to reach $3 billion in 2015 from $530 million in 2011.
