Enterprises Cloud SaaS and IaaS are an unstoppable force sweeping through organizations large and small at a breakneck pace. The rapid adoption has allowed anyone in an organization with a Web browser and an Internet connection to take over (and pay for) traditional IT department functions such as email, storage and backup, and collaboration tools. As a result of this rapid shift, IT consultancy Gartner estimates that by 2015, 35% of IT spending will come from budgets outside of the IT department. That figure will grow to 90% by the end of the decade. The benefits of these fast-growing cloud services are undeniable and include service agility; wider choice of products; ease of collaboration; fast, cheap deployment, and swapping fixed capital expenditures for variable operating costs that can be ratcheted up or down to meet demand. While enterprises have long leveraged traditional cloud services such as Salesforce.com and Office 365, employees increasingly use popular but lesser known services, such as Evernote (social bookmarking and document sharing) and Prezi (online presentation tools). They also log into SaaS services while at work for personal needs including photo sharing (Instagram), and social media (Twitter).cloud securitycloud security services
