Today, we work and live in an increasingly digital world, which not only gives individuals and businesses the agility and flexibility to create, share and store information virtually but also allows them to access a wide range of subscription-based virtual services. For example, if you use Salesforce, Netflix, Office 365 or Adobe Creative Cloud, you’re using Software as a Service (SaaS) and If you are a developer using Microsoft Azure, Heroku, Force.com or Google App Engine, you’re using Platform as a Service (PaaS), which gives enterprises plug-and-play pre-built blocks developers can use to create customized apps and solutions. To give enterprise networks just as much agility and flexibility, there is also Network-as-a-Service (NaaS).
