Ethereum Gateway support for Görli + Sepolia Testnets and the Ethereum Merge
Today we are excited to announce support for the Ethereum Merge on the Ethereum network and that our Ethereum gateways now support the Görli and Sepolia test networks (testnets). Sepolia and Görli testnets can be used to test and develop full decentralized applications (dapps) or test upgrades to be deployed on the mainnet Ethereum network. These testnets also use the Ethereum protocol, with the major difference that the Ether transacted on the testnet has no value.
Ethereum is a decentralized blockchain with smart contract functionality which Cloudflare allows you to interact with through an HTTP API. For a quick primer on Ethereum and our gateway, please refer to our previous blog post on the Ethereum Gateway.
As preparation for the merge, the Ethereum Foundation has executed merges on multiple testnets to ensure that the actual mainnet merge will occur with minimal to no disruption. These testnets both successfully upgraded to Proof of Stake and Proof of Authority, respectively. Cloudflare’s Testnet Gateway handled the Görli-Prater merge without issue, ensuring that we will be ready and prepared for the upcoming Ethereum Merge for mainnet. Our testnet gateways are live and ready for use by Cloudflare Ethereum Gateway customers.

Infrastructure-as-Code Sounds Scary
One of my readers preparing for public cloud deployment sent me an interesting observation:
I pushed to use infrastructure-as-code as we move to Azure, but I’m receiving a lot of pushback due to most of the involved parties not having any experience with code. Management is scared to use any kind of “homegrown” tools that only a few would understand. I feel like I’m stuck deploying and managing the environment manually.
It looks like a bad case of suboptimal terminology for this particular audience. For whatever reason, some infrastructure engineers prefer to stay as far away from programming as possible1, and infrastructure-as-code sounds like programming to them.

Hello my friend,
Once we are sorted with the theoretical part of how we are to deploy OpenStack, we are moving to a practical bit. Today we are going to explain the steps we are going to take in order to deploy OpenStack, the supporting storage and how they are to be integrated.

Linux Bonding, LLDP, and MAC Flapping
Sometimes a painfully troublesome networking problem can have a complicated and brain-twisting root cause, one which you dread having to explain to peers and managers. However, sometimes the root cause is dead simple and makes you feel silly for how long it took you to find it. Today, I had one of the latter and […]

In the last blog post in the VLANs and VRFs in netlab series, I described how we can combine VLANs and VRFs and create a VRF Lite solution with stretched VLANs. Wonder how hard would it be to create a routed multi-hop VRF Lite topology? It’s trivial.

Andrea Dainese released an interesting tool that performs automated network discovery, pushes the discovered data into NetBox, and then uses netbox-topology-views plugin to create network topology diagrams.
Definitely worth exploring!

After decades trailing the rest of the world in leading-edge chip making, Chinese sand stamper Semiconductor Manufacturing International Corporation (SMIC) has quietly got into the 7nm business. That’s a huge and unexpected leap. Has the West’s embargo of the latest fab furniture failed?

Although the United States and China are not engaged in traditional warfare, they are engaged in a war of ideas, trade, and technology, especially in semiconductor hegemony, where both sides are battling for supply and advancement.

Trade was global, the world was inextricably connected, and your job’s in China now but you should thank us, actually, because everything is cheap and fast and out-of-work factory workers can simply learn to code.

Fun Times: Is Cisco ACI Dead?
A recent blog post by Andrew Lerner asks whether Cisco ACI is dead. According to Betteridge’s law of headlines, the answer is NO (which is also Andrew’s conclusion), but I liked this gem:
However, Gartner assesses that Nexus Dashboard Fabric Controller is the optimal fabric management software for most Cisco data center environments.
An automation intent-based system provisioning a traditional routed network is considered a better solution than a black-box proprietary software-defined blob of complexity? Who would have thought…

IT/OT convergence isn’t enough. The real benefits come when network technology joins IT and OT in a powerful trifecta.Brand Protection
I woke up at 5am this morning to order a new iPhone. I did this because I wanted the new camera upgrades along with some other nice-to-haves. Why did I get an iPhone and not a new Samsung? Why didn’t I look at any of the other phones on the market? It’s because I am a loyal Apple customer at this point. Does that mean I think the iPhone is perfect? Far from it! But I will choose it in spite of the flaws because I know it has room to be better.
That whole story is repeated time and again in technology. People find themselves drawn to particular companies or brands. They pick a new phone or computer or car based on their familiarity with the way they work or the design choices that are made. But does that mean they have to be loyal to that company no matter what?

One of the things that I feel is absolutely paramount to being a trusted advisor in the technology space is the ability to be critical of a product or brand. If you look at a lot of the ambassador or influencer program agreements you’ll see Continue reading
