</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
AWS Interconnect is a managed service that provides private, high-speed connections between AWS and other cloud providers (starting with Google Cloud, with Azure and Oracle Cloud coming in 2026), as well as on-premises networks through partner providers like Lumen. The service automatically provisions redundant connections with MACsec encryption across multiple facilities, eliminating the manual configuration of VPN tunnels and third-party network fabrics that enterprises previously had to manage themselves.

<strong>Project Think: building the next generation of AI agents on Cloudflare (12 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Project Think is a next-generation agent SDK that introduces primitives like durable execution, sub-agents, sandboxed code execution, and persistent sessions to enable long-running AI agents that cost zero when idle and automatically scale—solving the economic challenge of running millions of simultaneous agent sessions that would be unsustainable at current per-container costs. The platform builds on Cloudflare's Durable Objects to give each agent its own identity and SQLite database, while new features like Dynamic Workers (100x faster than containers), runtime npm resolution, and self-authored extensions let agents write their own tools and operate across a five-tier "execution ladder" from filesystem operations to full OS access.

<strong>Scaling MCP adoption: Our reference architecture for simpler, safer, and cheaper enterprise deployments of MCP (11 minute read)</strong>
</span>

<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Cloudflare deployed Model Context Protocol (MCP) company-wide across engineering, product, sales, marketing, and finance teams, securing the rollout with a centralized architecture that includes remote MCP servers on their developer platform, Cloudflare Access for authentication, and newly launched "Code Mode" that reduces token costs by 94-99.9% by collapsing dozens of tool definitions into just two search-and-execute functions. The company also integrated shadow MCP detection through Cloudflare Gateway to identify unauthorized remote MCP servers, while protecting public-facing MCP servers with their Web Application Firewall to guard against prompt injection and data leakage attacks.

<strong>Load Balancing and Scaling LLM Serving (6 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Load balancing for large language models requires specialized cache-aware routing strategies because traditional round-robin approaches can degrade prompt cache hit rates from 50-90% efficiency down to just 1/N across N replicas, eliminating the cost and latency benefits. A new technique called precise prefix cache-aware routing—which uses radix trees and real-time KV cache events from inference engines—can improve throughput by up to 108% compared to standard Kubernetes load balancing by ensuring requests hit servers that already have relevant conversation history cached.

GenericAgent, a new open-source autonomous agent framework with just 3,000 lines of core code, gives LLMs system-level control over local computers through 9 atomic tools and can automatically crystallize solved tasks into reusable skills that accumulate over time. The framework proved its capabilities by autonomously completing its own GitHub repository setup—including Git installation and all commit messages—without any manual terminal input from its creator.
