Cloud computing. You know it's big, but how big? Well, let's just say this trend isn't all buzz. This infographic by Cloudability shows that most companies are using multiple clouds, and 86 percent use more than one type of cloud service for everything from hosting to CRM to crowdsourcing. Cloud computing services such as software as a service (SaaS), infrastructure as a service (IaaS) and platform as a service (PaaS) can reduce enterprise costs and increase flexibility and scalability. So, next time someone says your *aaS looks big, take it as a compliment!
