Cloud computing is popular and every organization is migrating into this platform because of almost zero lead time to provision the infrastructure without waiting for delivery, installation, configuration and commissioning. Further, manpower resource to manage the infrastructure is shifted into service provider. Of course, this refers to using Cloud outside the organization rather than an on-premise private Cloud.
While Cloud computing (no matter Iaas, PaaS, SaaS) has many merits, the overlooked layer is the bandwidth from your organization to the hosting site. This is the most critical infrastructure to maintain survivability in terms of resilience and business continuity plan.
