What our engineers learned this week. Hands-on technical deep-dives, postmortems, and strategy frameworks.
How we found a bug in the hyper HTTP library
The Images service, built in Rust on Workers , runs on every machine in Cloudflare’s edge network. To handle client connections, we use hyper , an open-source HTTP library for Rust. Last year, we introduced the Images binding to enable custom, programmatic workflows for processing remote images in Workers. At the end of 2025, we rearchitected the binding to provide a more direc
AWS Weekly Roundup: NY Summit recap, Local Zone in Hanoi, Grok 4.3 in Bedrock, price reductions, and more (June 22, 2026)

Agents for working – You can launch au
Temporary Cloudflare Accounts for AI agents
Everyone's writing code with AI agents today. But the moment an agent needs to deploy something — and needs to sign up and create an account — it slams face-first into a wall built for humans: a browser-based OAuth flow, a dashboard to click through, an API token to copy-paste, a multi-factor authentication prompt to satisfy. For an interactive copilot sitting next to a develop
Announcing Amazon EC2 G7 instances accelerated by NVIDIA RTX PRO 4500 Blackwell Server Edition GPUs
Today, we’re announcing the general availability of Amazon Elastic Compute Cloud (Amazon EC2) G7 instances, delivering high performance GPU acceleration for AI inference, graphics, and data analytics workloads.

Amazon ECS introduces new high-resolution metrics for faster service auto scaling
Amazon Elastic Container Service (Amazon ECS) service auto scaling automatically adjusts task counts to meet workload demand with comprehensive scaling policies, including predictive scaling for recurring traffic patterns, scheduled scaling for planned events, and target tracking to scale dynamically on real-time metrics. You can choose proactive scaling by using predictive sca
Build your own vulnerability harness
A few weeks ago, we published our initial findings from Project Glasswing , looking at what happens when you point frontier security models at an enterprise codebase. We also explored how our defensive structures adapt to protect our infrastructure and customers from threats posed by frontier AI . Since then, the AI ecosystem has continued to shift rapidly — developers who've b
Celebrating 12 years of Project Galileo
Twelve years ago this month, Cloudflare launched an ambitious project built on a simple idea: people shouldn’t be knocked offline just because someone more powerful disagrees with them. Today, Project Galileo provides free access to cybersecurity services to more than 3,400 websites belonging to journalists, human rights defenders, and other nonprofit organizations in 120 count
AIBringing more agent harnesses and frameworks to Cloudflare, starting with Flue
Cloudflare is launching its Agents SDK as a foundational platform layer for production-grade AI agents, addressing distributed systems challenges like durable execution, state management, and secure code execution. The company introduces Flue, an open-source agent framework built on the Pi harness, which offers a declarative approach to building agents with built-in integrations for enterprise too
AITop announcements of the AWS Summit in New York, 2026
AWS Summit New York 2026 focused heavily on agentic AI capabilities, with major announcements centered on Amazon Bedrock AgentCore enhancements for enterprise AI agent development. Key launches include managed knowledge bases, web search integration, AI traffic monetization through AWS WAF, and security automation tools like AWS Continuum that operate at machine speed to identify and remediate vul
AIAnnouncing Web Search on Amazon Bedrock AgentCore: Ground your AI agents in current, accurate web knowledge
AWS has launched Web Search on Amazon Bedrock AgentCore, a fully managed tool that enables AI agents to ground responses in current web knowledge while keeping all data within customers' AWS environments. The service leverages Amazon's search infrastructure and combines web index data with structured knowledge graph information to provide more accurate responses than traditional web search, elimin
AIIntroducing Amazon Bedrock Managed Knowledge Base for faster, more accurate enterprise AI applications
AWS has launched Amazon Bedrock Managed Knowledge Base, a fully managed service that simplifies building enterprise RAG (retrieval-augmented generation) pipelines for generative AI applications. The service abstracts infrastructure complexity by providing native connectors to six enterprise data sources, intelligent parsing capabilities, and an agentic retriever for complex queries. Developers can
AIIntroducing the Cloudflare One stack: agent-powered deployment
Cloudflare has launched the Cloudflare One stack, an agent-powered toolkit designed to automate the configuration, deployment, and management of Zero Trust network architectures. The stack provides AI agents with structured knowledge and tools to handle complex migration tasks from legacy SASE vendors like Zscaler and Palo Alto Networks, reducing implementation timelines from months to hours. Buil
AIModernize your data with Azure Storage: Plan and migrate with confidence
Enterprise storage migrations to Azure require strategic planning beyond simple data copying, addressing business continuity, performance, and cost management. Microsoft offers a comprehensive migration framework combining Azure Migrate for assessment and planning with specialized tools like Azure Storage Mover for online transfers and Azure Data Box for offline bulk migrations. The approach empha
AIAmazon S3 annotations: attach rich, queryable context directly to your objects
Amazon S3 has introduced annotations, a new metadata capability that allows organizations to attach up to 1 GB of rich, queryable business context directly to storage objects without rewriting them. This feature addresses limitations of existing metadata options by supporting mutable, large-scale context in flexible formats (JSON, XML, YAML, plain text) that automatically moves with objects during
