SMBs faced a 273x increase in security threats this year β N-able report (Sponsor)
Attackers are no longer skipping over smaller businesses. In fact, they're increasingly targeting them. The
N-able team observed a surge in detected threat instancesβfrom approximately 48,749 in June 2024 to over 13.3 million by June 2025.
That means SMBs now face enterprise-level threats without enterprise-level resources. Read the 2025 Annual Threat Report to understand:
β Top attack trends shaping 2025, including AI-driven exploits and supply chain risks.
β Why mid-market IT teams are prime targetsβand how to harden your environment.
β Practical steps to reduce exposure and improve resilience without adding headcount.

How Google Does It: Building the largest known Kubernetes cluster, with 130,000 nodes (6 minute read)
Google Cloud proved GKE can scale to an experimental 130,000-node cluster, sustaining 1,000 Pods/sec and over 1M objects. New control-plane optimizations, advanced scheduling with Kueue, and improved storage and data access enable massive, dynamic AI workloads at extreme scale.
Datacenters in space are a terrible, horrible, no good idea (9 minute read)
Datacenters in space are wildly impractical because they can't be powered, cooled, or protected from radiation anywhere close to what modern GPUs require, making them orders of magnitude less efficient than Earth-based datacenters. Even with massive solar arrays, complex radiators, and radiation-hardened designs, you'd get only a tiny fraction of normal compute capacity at enormous cost, so the idea simply doesn't make sense.
How to monitor Amazon Bedrock AgentCore AI agent infrastructure in Grafana Cloud (7 minute read)
Grafana Cloud users can now monitor AWS Bedrock AgentCore agents by configuring CloudWatch metric streams. The new integration leverages OpenTelemetry, Amazon CloudWatch, and Grafana Cloud to provide end-to-end visibility into AI agent performance, including dashboards that track latency, token usage, and tool execution. Users also gain immediate access to pre-built dashboards and alerts tailored to AWS metrics through the Cloud Provider Observability application.

Open-Sourcing Adaptive Workflows for AI-Driven Development Life Cycle (AI-DLC) (7 minute read)
AWS' AI-Driven Development Life Cycle (AI-DLC) methodology addresses challenges in AI-integrated software development by promoting adaptive workflows, flexible depth in each stage, and consistent human oversight. The AI-DLC workflow, now available as open-source Amazon Q Rules and Kiro Steering Files, guides AI through software creation, ensuring AI adapts to the project's needs. This method uses collaborative human-in-the-loop cycles, where AI generates a plan to execute a task, and relevant stakeholders assemble, review, and validate it.
