Shares of Amazon ( AMZN +3.99%) jumped on Monday, finishing the day up 5%. The move higher came as the S&P 500 gained 0.1% and the Nasdaq Composite rose 0.4%. The tech behemoth inked a major deal to provide OpenAI with $38 billion worth of artificial intelligence (AI) computing capacity.

A massive internet outage stemming from errors in Amazon cloud services on Monday morning demonstrated just how many people rely on the corporate behemoth's computational infrastructure everyday — and laid bare the vulnerabilities of an increasingly concentrated system.

The cloud-computing division of the internet giant is used by thousands of internet customers, many of whom reported disruptions on Monday.

Experts say the incident revealed what can happen when a such a broad spectrum of companies rely on singular cloud provider.

Amazon is scheduled to report third-quarter earnings after markets close on Thursday, and all eyes are likely to be on the e-commerce giant’s cloud business.
