Federal, state, and local agencies can purchase commercial cloud computing services and specialized labor to support cloud adoption through Cloud computing and cloud related IT professional services, known as the Cloud SIN.
Buying from the Cloud SIN helps your agency:
Expedite market research by listing hundreds of cloud vendors all in one place. Cloud IaaS/PaaS/SaaS and associated labor hours are included.
Offload some steps in the acquisition process since GSA takes care of things like vetting vendors’ financial stability, conducting fair and reasonable pricing analysis, etc.; things that the agency would have to conduct in an open market buy.
Streamline the acquisition by offering pre-vetted cloud products/services at pre-negotiated rates.
Ensure compliance through GSA’s pre-vetting of all cloud products/services.
Run solicitations/competitions/evaluations faster by using a smaller pool of pre-approved vendors.
Scope
Agencies can acquire commercial cloud computing services and any solution that meets the NIST definition of cloud computing:
Infrastructure as a Service: Computing resources like virtual servers, storage, and networking (e.g., bare-metal as a service, data center as a service, disaster recovery).
Platform as a Service: Tools and platforms for application deployment, such as database as a service or backend as a service.
Software as a Service: Ready-to-use cloud applications, including office productivity, Customer Relationship Management, and video conferencing tools.
Emerging services like cloud-based Artificial Intelligence/Machine Learning (AI/ML). You can purchase tools with these advanced computing capabilities offered as cloud software as a service. Examples include large language models and AI chatbots.
