From Python to Go 020. Concurrency and Parallelism Of Code Executions.

Hello my friend,

Today’s topic is critical to complete full picture of software development for network automation. Today’s topic is what allows you to conduct your tasks within meaningful time frame, especially when you have a lot of network devices, servers, virtual machines to manage. Today’s topic is concurrency of code execution in Python and Golang.

What Other Programming Languages Makes Sense To Study?

There are more than 100 programming languages out there. Some of them are quite universal and allow development of almost any kind of application. Others are more specific. Python is probably the most universal programming language, from what I’ve worked with or heard of. It can be used in infrastructure management at scale (e.g., OpenStack is written in Python), web applications, data science and many more. Golang is much more low-level compared to Python and, therefore, way more performant. Various benchmarks available online suggests that the same business tasks could be 3-30 times quicker in Golang compared to Python; therefore Golang is suitable for system programing (e.g, Kubernetes and Docker are created in Go). That’s what we cover in our blogs. Apart from them there are a lot of other: C/C++ if you Continue reading

HN779: Do We Really Need the Modern Networking Stack?

On today’s Heavy Networking, a roundtable panel considers whether a modern network needs to be built around underlays and overlays. This isn’t just Ethan yelling at clouds. This is a legitimate question pondering the real-world value of an overlay/underlay approach. Is overlay everywhere overkill, or is that the architecture we need to deliver a safe,... Read more »

Amazon Says It Can Embiggen AWS Past “Multi-$100 Billion” With AI

Here is how you know the cloud revolution is not done: Throughout the 77 quarter financial history of Amazon Web Services, which was formally launched in March 2006, there have been so few quarters of sequential revenue decline that you can literally count them on one hand. …

Gateway API or Ingress: A Developer’s Guide to Kubernetes Routing

Managing how applications within a Kubernetes cluster communicate with the outside world is a fundamental challenge. For years, the standard approach involved the multiple annotations to configure the ingress resource, which makes it confusing and cumbersome to manage. Recognizing these limitations, the Kubernetes community developed the Gateway API, a more powerful, flexible and standardized successor designed to streamline traffic management. The Ingress controller, a separate piece of software running in the Continue reading

Hedge 268: Will AI take our jobs?

One of the “great fears” advancing AI unlocks is that most of our jobs can, and will, be replaced by various forms of AI. Join us on this episode of the Hedge as Jonathan Mast at White Beard Strategies, Tom Ammon, and Russ White discuss whether we are likely to see a net loss, gain, or wash in jobs as companies deploy LLMS, and other potential up- and down-sides.

Thirteen new MCP servers from Cloudflare you can use today

You can now connect to Cloudflare's first publicly available remote Model Context Protocol (MCP) servers from Claude.ai (now supporting remote MCP connections!) and other MCP clients like Cursor, Windsurf, or our own AI Playground. Unlock Cloudflare tools, resources, and real time information through our new suite of MCP servers including:

MCP Demo Day: How 10 leading AI companies built MCP servers on Cloudflare

Today, we're excited to collaborate with Anthropic, Asana, Atlassian, Block, Intercom, Linear, PayPal, Sentry, Stripe, and Webflow to bring a whole new set of remote MCP servers, all built on Cloudflare, to enable Claude users to manage projects, generate invoices, query databases, and even deploy full stack applications — without ever leaving the chat interface. 

Since Anthropic’s introduction of the Model Context Protocol (MCP) in November, there’s been more and more excitement about it, and it seems like a new MCP server is being released nearly every day. And for good reason!  MCP has been the missing piece to make AI agents a reality, and helped define how AI agents interact with tools to take actions and get additional context.

But to date, end-users have had to install MCP servers on their local machine to use them. Today, with Anthropic’s announcement of Integrations, you can access an MCP server the same way you would a website: type a URL and go.

At Cloudflare, we’ve been focused on building out the tooling that simplifies the development of remote MCP servers, so that our customers’ engineering teams can focus their time on building out the MCP tools for their Continue reading

With Its Llama API Service, Meta Platforms Finally Becomes A Cloud

Bringing streamable HTTP transport and Python language support to MCP servers

We’re continuing to make it easier for developers to bring their services into the AI ecosystem with the Model Context Protocol (MCP). Today, we’re announcing two new capabilities:

• Streamable HTTP Transport: The Agents SDK now supports the new Streamable HTTP transport, allowing you to future-proof your MCP server. Our implementation allows your MCP server to simultaneously handle both the new Streamable HTTP transport and the existing SSE transport, maintaining backward compatibility with all remote MCP clients.

• Deploy MCP servers written in Python: In 2024, we introduced first-class Python language support in Cloudflare Workers, and now you can build MCP servers on Cloudflare that are entirely written in Python.

Click “Deploy to Cloudflare” to get started with a remote MCP server that supports the new Streamable HTTP transport method, with backwards compatibility with the SSE transport. 

The MCP spec was updated on March 26 to introduce a new transport mechanism for remote MCP, called Streamable HTTP. The new transport simplifies how AI agents can interact with services by using a single HTTP endpoint for sending and receiving responses between the client and the Continue reading

OSPF Summary LSA Loop Prevention

A networking-focused entity known only as humblegrumble sent me the following question after reading my When OSPF Becomes a Distance Vector Protocol article:

How do A1 and A2 know not to advertise a Type-3 summary LSA generated from area 1 prefixes back into area 1?

He’s right. There is no “originating area” information in the type-3 LSA, so how does an ABR know not to reinsert the type-3 LSA generated by another ABR back into the area?

TL&DR: The OSPF route selection process takes care of that.

Synadia Attempts To Reclaim NATS Back From CNCF 

It has become almost commonplace to read about yet another company having regrets about open sourcing their flagship product and relicensing it under a semi-proprietary license. Yes, I’m looking at you, Hashicorp, MongoDB and Redis. Now, though, Synadia, the original creator and donor of the switching NATS’ open source Apache 2 license to the Business Source License (BSL). But, there’s a fly in the soup. You see, Synadia founder and CEO, Synadia and its predecessor company funded approximately 97% of the NATS server contributions.” Therefore, “For the NATS ecosystem to flourish, Synadia must also Continue reading
