AWS Raises GPU Prices 15% on a Saturday

AWS increased GPU prices for EC2 Capacity Blocks by 15%, raising rates for major instances without prior warning on a Saturday. This shift, noted in January 2026, challenges the established expectation of decreasing cloud costs and raises concerns about future pricing trends, impacting companies reliant on machine learning workloads. Analysts speculate on a broader trend amid global resource constraints, potentially affecting other AWS services. Competitors may leverage this price hike as a marketing advantage.

How Amazon Finds Its Cybersecurity Weak Spots

Amazon avoids typical cybersecurity benchmarks and instead monitors the introduction of new and old devices in its network in real time, believing these are key to spotting risks. The company leads with meticulously detailed metrics instead of using averages or simple dashboards and shares its findings with a specialized security board committee. This approach, guided by Chief Security Officer Stephen Schmidt, emphasizes outlier risks and continuous oversight, setting Amazon apart from peers.

How Can CIOs Keep Operations Going During an Outage?

A major AWS outage hit thousands of companies, but only those using the affected US-EAST-1 data center. This highlighted the risks of depending on a single cloud provider. IT leaders stress the need for redundancy—such as backups and failovers—to reduce the operational impact of outages, particularly for mission-critical systems. However, there are financial trade-offs: not every system needs full redundancy, and organizations must prioritize based on risk, sector, and potential impact. While using a single provider can be efficient and drive innovation, CIOs must still prepare for outages by architecting for failure within their provider’s ecosystem, auditing for high-impact dependencies, and ensuring they have strong contingency and recovery plans. Highly regulated or always-on industries require higher resilience, but in all cases, informed risk management is key.

AWS in 2025: The Stuff You Think You Know That’s Now Wrong

AWS has evolved significantly over nearly two decades, now featuring capabilities like live migration of EC2 instances, read-after-write consistency in S3, improved Lambda performance, and more reliable DynamoDB. Key changes include the removal of EC2-classic, adjustments in networking costs, introduction of cost-saving features, and enhanced IAM for authentication. Many legacy assumptions about AWS services are now outdated, reflecting a more durable and user-friendly platform.
