From AT&T Support Wiki
Service Providers are ISVs (Independent Software Vendors) and MSPs (Managed Service Providers) who design, develop and deploy web-based business applications that connect information, people and processes in the AT&T PaaS Platform.
The key differences are:
- ISVs host the AT&T PaaS Platform on servers they manage, while MSPs use an ISV-hosted instance of the AT&T PaaS Platform
- Configuration options differ for ISVs and MSPs, because hosting is controlled at a different level
Independent Software Vendors (ISVs) are Service Providers who use the Installable Version of the platform.
- Design custom application solutions
- Set up Collaborative Development Configurations
- Manage Tenants and MSPs in a self-hosted environment, to support users in multiple tenancies.
- Use Service Provider Settings to specify global settings that apply to all tenants
- Manage Tenant Capabilities to specify settings for individual tenants
- Customize the user interface, support information and branding for tenants.
Managed Service Providers (MSPs) are Service Providers who work with ISV Partners to design custom application solutions.
