A cloud service provider (CSP) is a company that delivers computing resources, platforms, or applications to customers over the internet on a pay-as-you-go or subscription basis. The term spans a wide range of companies, from hyperscale infrastructure providers like AWS, Microsoft Azure, and Google Cloud to regional hosting companies and specialized SaaS vendors.
Service models and business structure
Cloud service providers operate data centers (or lease capacity from those who do) and offer customers access to computing infrastructure without requiring those customers to own or manage physical hardware. The services they provide fall into three broad categories.
Service models
- Infrastructure as a Service (IaaS): The provider supplies virtualized compute, storage, and networking resources. The customer manages the operating system, middleware, and applications. Examples: virtual machines, block storage, virtual networks.
- Platform as a Service (PaaS): The provider supplies a development and deployment environment. The customer builds and runs applications without managing the underlying infrastructure. Examples: managed databases, serverless functions, container orchestration platforms.
- Software as a Service (SaaS): The provider delivers a fully managed application. The customer uses the software through a browser or API without managing any infrastructure. Examples: CRM systems, collaboration tools, accounting software.
Business model
CSPs typically charge based on consumption (compute hours, storage gigabytes, API calls) or through fixed subscriptions. Enterprise customers often negotiate committed-use agreements that provide discounted rates in exchange for guaranteed minimum spend.
The CSP’s multi-faceted role in the channel
Cloud service providers occupy a unique position in the channel ecosystem, functioning simultaneously as vendors, partners, and platforms.
As vendors
CSPs sell their own services (compute, storage, AI/ML, security) through both direct sales and partner channels. AWS, Azure, and Google Cloud each maintain large partner programs with thousands of channel partners who resell, implement, and manage cloud services.
As partners
ISVs and other technology companies partner with CSPs to reach customers through cloud marketplaces, co-sell programs, and technology integrations. For these companies, the CSP is a channel partner that provides access to a massive installed base.
As platforms
CSPs provide the infrastructure on which other companies build and deliver their products. The CSP’s ecosystem of ISVs, system integrators, and managed service providers creates a network effect: more applications on the platform attract more customers, which attract more partners.
This multi-role dynamic means that channel practitioners regularly interact with CSPs from multiple angles. A vendor might sell through a CSP’s marketplace, partner with a CSP’s sales team on a co-sell motion, and build on the CSP’s infrastructure.
CSP partner programs and go-to-market considerations
CSP partner programs
Each major CSP operates a partner program with its own structure:
| Provider | Program | Key partner types |
|---|---|---|
| AWS | AWS Partner Network (APN) | Consulting partners, technology partners, distribution partners |
| Microsoft | Microsoft Cloud Partner Program | Solutions partners, managed partners, ISVs |
| Google Cloud | Google Cloud Partner Advantage | Sell partners, service partners, build partners |
These programs offer partners access to training, co-sell opportunities, marketplace listing, technical support, and financial incentives (often tied to customer consumption growth).
Working with CSPs as a channel strategy
For ISVs and other vendors, building a CSP partnership involves several practical steps:
- Technical integration: Ensure the product runs well on the CSP’s platform and is listed on the marketplace.
- Co-sell alignment: Register joint opportunities with the CSP’s sales team. Align on target accounts where the ISV’s solution complements the CSP’s platform.
- Consumption incentives: Many CSP partner programs reward partners for driving customer cloud consumption. Understanding these incentives helps partners position joint solutions effectively.
- Marketplace enablement: Configure private offers and partner-assisted transactions so that channel partners can participate in marketplace deals.
Cloud service provider vs. managed service provider
A cloud service provider owns and operates the underlying infrastructure or platform. A managed service provider (MSP) is a channel partner that manages cloud environments on behalf of end customers, often using one or more CSPs’ infrastructure. The CSP provides the raw capability; the MSP provides the operational management layer that many customers need.
