The Scale and Quality of the AWS Partner Network (APN) - The ISV and SI Partners Powering the Ecosystem
This article compares the number and quality of ISV and SI partners in the APN and Marketplace listing counts with Azure and GCP, explaining the business advantages that the depth of the AWS ecosystem provides.
APN Overview and Partner Count
The AWS Partner Network (APN) is one of the world's largest cloud partner ecosystems, with over 130,000 participating partners as of 2025. Partners are broadly classified into ISVs (Independent Software Vendors) and SIs (System Integrators), where ISVs provide software products that run on AWS and SIs provide implementation support and managed services. Azure's partner network is also large-scale, but AWS holds an advantage in enterprise ISV participation thanks to its first-mover advantage. GCP's partner ecosystem has strengths in data analytics and AI, while tending to have thinner coverage in general-purpose business application areas compared to AWS and Azure.
Competency and Specialization Programs
APN features two certification systems - the Competency Program and the Service Delivery Program - that objectively evaluate partner technical capabilities and track records. Competencies are defined for specific industries (healthcare, financial services, manufacturing, etc.) and technology domains (security, machine learning, IoT, etc.), requiring technical reviews and customer case study submissions for certification. This review process gives users confidence in a baseline quality when selecting certified partners. Azure has a similar specialization system, but AWS competencies are more finely segmented by domain, making it easier to find highly specialized partners. Partner tiers are structured in three levels - Select, Advanced, and Premier - with increasingly stringent requirements at higher tiers.
ISV Partner Quality and Marketplace Listing Count
AWS Marketplace features over 17,000 software listings as of 2025, comparable in scale to Azure Marketplace's approximately 18,000 listings. GCP Marketplace has around 3,500 listings, showing a gap in the breadth of options. A distinguishing feature of AWS Marketplace is the diversity of listing formats, including AMIs, container images, SaaS, and professional services. In security, networking, and DevOps categories in particular, virtually all major vendors list their products on AWS Marketplace, enabling end-to-end procurement and billing management within AWS. From an ISV partner quality perspective, a major strength is that cloud-native companies like CrowdStrike, Datadog, and Snowflake develop their products with AWS as the primary platform.
SI Partners and Managed Service Providers
The depth of SI partners is a significant AWS advantage, particularly in the Japanese market. Major SI firms including NTT DATA, Fujitsu, NEC, and TIS operate as AWS Premier Consulting Partners, providing migration support from on-premises and managed services. AWS also runs a Managed Service Provider (MSP) program, where certified MSPs provide comprehensive operational monitoring, cost optimization, and security management. Azure has many SIs with strengths in Microsoft product integration, while GCP tends to attract SIs specializing in data analytics platform construction. When selecting a cloud provider, the availability of SI partners with expertise in your industry and technical requirements is a critical factor that significantly reduces implementation risk.
Partner-Led Innovation and Co-Development
The value of APN extends beyond partner count to the innovation born from co-development between AWS and partners. AWS promotes the Co-Sell program, where ISV partners jointly develop industry-specific solutions and AWS sales teams directly support partner product sales. The AWS SaaS Factory program provides technical support and best practices to help ISVs accelerate their transition to SaaS models. The richness of these programs motivates partners to continue investing in the AWS ecosystem, creating a virtuous cycle that expands the breadth and quality of solutions available to end users. To deepen your understanding of cloud ecosystems, related books on Amazon can also be helpful.
The Business Implications of APN's Scale
The scale of a partner ecosystem is often overlooked in cloud selection, yet it has significant practical impact. A larger partner count makes it easier to find specialists who can address specific industry requirements and technical challenges, increasing the success rate of implementation projects. A larger Marketplace listing count increases the likelihood of building systems by combining off-the-shelf solutions rather than custom development, compressing development costs and timelines. The AWS ecosystem has formed the thickest layer to date through the virtuous cycle of first-mover advantage and partner investment. However, Azure is expanding its own ecosystem around Microsoft 365 and Dynamics 365 integration, making it a strong option particularly in the enterprise IT management space.
