Architecting Tenant Networking with NSX in vCloud Director : Introduction
   
Introduction
1.1 Overview
The VMware Cloud Provider Program is an ecosystem of over 4,000 service providers located in more than 100 countries offering VMware based cloud services. Local providers secure data sovereignty while providing a wide range of cloud services and vertical market expertise through specialized compliance and certifications.
VMware Cloud Providers are uniquely positioned to offer their services to the market and become a seamless extension of existing VMware enterprise customers’ on-premises data centers. Managed service providers have traditionally operated data centers hosting multiple tenants and have developed reference topology models offering tenant separation while allowing the provider to offer value-add services that require access into each tenant environment from common management platforms.
One of the initial concerns about offering a multitenant platform using a customer-facing, overlaid management solution, such as VMware vCloud Director®, is understanding the capabilities and constraints for the customer solutions that can be delivered and for the service provider infrastructure which will support these solutions. With the inclusion of VMware NSX® in later releases of vCloud Director, the ability to create complex customer topologies has increased, but so have the concerns which can justifiably be raised over the deployment of both products technically and operationally.
