Our take
Managing cloud deployments effectively to control costs has become a priority for organizations of all sizes. Cast AI drives cloud optimization and cost reduction by using AI and machine learning to analyze a company’s cloud environment to identify the resources required for maximum performance.
Cast AI’s platform supports all three major cloud service providers; Microsoft Azure, Google Cloud, and Amazon Web Services. When cloud providers have unused machines they are typically discounted by 60-70%, however, if AWS (for example) needs that machine back, they give little warning before reclaiming it. Cast AI is able to automatically detect this, and immediately replace it, meaning companies using its platform will never experience an outage of discounted machines.
As more enterprises embrace cloud and AI technologies, Cast AI has continued to strengthen its position through global expansion and enterprise adoption. The company recently introduced OMNI Compute, a unified compute control plane designed to optimize workloads and PGU usage across cloud providers, while also surpassing a $1B valuation following strategic investment to support its long-term growth and international expansion.
