The infrastructure landscape is under pressure. As AI-driven agents and automation reshape how businesses operate, traditional infrastructure approaches — rigid, slow, and siloed — are proving inadequate. Organizations face mounting demands for platforms that can adapt rapidly, deliver services dynamically, and support continuous innovation. To meet this challenge, Forrester introduces the OASIS Framework, a forward-looking model that defines five foundational capability areas leaders must embed in infrastructure platforms. This engineering-oriented paradigm aligns infrastructure with business requirements, enabling both velocity and resilience in the emerging agentic AI era.
