Google will use Nuclear Energy for its AI centers
Google has partnered with Kairos Power to power its AI data centers using small nuclear reactors. This innovative approach aims to meet the growing energy demand of artificial intelligence while prioritizing clean energy solutions.
- The first reactor is expected to be operational by 2030, with more coming online by 2035.
- Kairos Power specializes in smaller reactors that use molten fluoride salt as a coolant, a departure from traditional water-cooled systems.
- This partnership reflects the growing interest of the tech industry in nuclear energy as a carbon-free and round-the-clock energy source.
- The agreement still requires approval from the U.S. Nuclear Regulatory Commission and local agencies.
As AI technology advances, data center energy consumption is projected to double by the end of the decade. Google's move signals a shift towards sustainable solutions in the face of rising energy demand.
This partnership is part of a broader trend, with other tech giants like Microsoft and Amazon also exploring nuclear options for their data centers. It aligns with the U.S. goal of tripling nuclear power capacity by 2050 and reducing dependence on fossil fuels.
Serverless
Lambda Doom Loop: A Halloween Nightmare for Serverless Developers
This week, we delve into a chilling discovery by serverless expert AJ Stuyvenberg. In his recent blog post, AJ reveals what he calls the "Lambda doom loop" - a new terrifying behavior in AWS Lambda that could haunt unsuspecting developers.
At the core of the issue is a recent change in the Lambda initialization process. Now, subsequent initializations of a Lambda function count towards the total timeout, which could lead to a devastating failure cycle if not managed properly.
AJ's article not only exposes this lurking danger but also offers four practical solutions to avoid the doom loop. It is a must-read for anyone working with Lambda, serving both as a warning and a guide to navigate this new tricky terrain.
As we approach Halloween, this timely discovery reminds us that even in the serverless world, there are still things that go bump in the night. Stay alert and don’t let the Lambda doom loop trick you this spooky season.

Cloud Native Architectures: Balancing Speed and Security
Cybersecurity expert Akhil Mittal shares valuable insights on the often-overlooked security challenges in cloud-native architectures. Drawing on his experience with a financial services company, Mittal highlights how the rush to innovate can inadvertently create significant vulnerabilities, particularly in API security.
- API vulnerabilities are becoming a common entry point for attackers, with 94% of organizations facing API security issues in 2023.
- Microservices offer flexibility but introduce complexity and increase security risks.
- Over-reliance on automation can lead teams to overlook critical system-level vulnerabilities.
- Implementing least privilege access, hardening control policies, and combining automation with manual audits are crucial steps to secure cloud-native architectures.
- Adopting a service mesh and chaos engineering principles can significantly enhance security and resilience.
Mittal's article serves as a wake-up call for organizations adopting cloud-native technologies, emphasizing that the pursuit of speed and innovation should not compromise security.
As we move towards 2025, when nearly half of enterprise APIs may be unmanaged, it is clear that a balanced approach between agility and security is not only beneficial but essential.

Netflix's Global Cache System: A Marvel of Distributed Architecture
Netflix reveals the complexities of its global cache system, EVCache. This distributed key-value store is the backbone of Netflix's ability to deliver content seamlessly to millions of users worldwide.
- EVCache spans 4 regions with 200 Memcached clusters and 22,000 server instances
- It handles the staggering figure of 400 million operations per second and manages 14.3 petabytes of data
- It uses client-initiated replication for efficient data routing and reduced server load
- It implements innovative error handling using Amazon SQS to ensure data reliability
- Recently optimized with batch compression and removal of network load balancers, significantly reducing costs
The article provides a comprehensive view of the architectural decisions and trade-offs made by Netflix engineers to build a system that is both highly efficient and cost-effective. It is a masterclass in distributed system design, showcasing how careful engineering choices can lead to remarkable scalability and resilience.
