Amazon's AWS Grows 18% in Q2 but Microsoft's 39% Surge Raises Cloud Stakes

Amazon's (NASDAQ: AMZN) cloud division posted an 18% revenue increase in Q2, pulling in $30.9 billion-a hair above analyst estimates. AWS, the heavyweight in cloud infrastructure, still holds the crown but is feeling the heat from Microsoft (NASDAQ: MSFT) and Alphabet (NASDAQ: GOOGL), both of whom are pouring serious resources into AI to capitalize on soaring demand.

Microsoft's CEO Satya Nadella recently dropped some new figures: Azure and the broader cloud outfit cleared $75 billion in revenue over the past fiscal year, with a stunning 39% quarterly growth. Alphabet's cloud revenues followed suit with a 32% jump to $13.6 billion. By comparison, AWS growth, while solid, looks a bit more modest.

In the latest quarter, AWS claimed $30.87 billion in revenue, making up about 18% of Amazon's overall sales. CEO Andy Jassy pointed out during the earnings call that AWS is significantly larger than its closest competitor, estimating the runner-up at roughly 65% of AWS's size.

Profit-wise, AWS remains a bright spot. The unit delivered $10.2 billion in operating income, slightly missing the average analyst target of $10.9 billion, while Amazon as a whole generated $19.2 billion. Jassy emphasized the importance of AWS's security and privacy capabilities, especially as customers entrust increasingly sensitive data to the cloud.

The quarter featured some operational moves too-AWS intends to launch a new data center region in Chile by 2027, expanding its global infrastructure. A notable new client win came from PepsiCo, which committed to shifting key workloads onto AWS under a multi-year deal.

Still, challenges remain. Supply chain hiccups are affecting AWS's ability to meet AI-related demand, particularly when it comes to energy resources. Similar concerns were echoed by Microsoft's finance chief, Amy Hood, who expects tight supply conditions through year-end.

It's clear that cloud is no longer just about storage or computing power-AI integration is the field's new battleground. AWS's growth is impressive, but Microsoft's and Google's aggressive advances signal that the fight for dominance is far from settled.
