Today's Full Stack Journey delves into developer advocacy: what is it, why do organizations have this role, and what makes a good developer advocate? Host Scott Lowe has invited four practitioners to tackle these questions. He speaks with Jacquie Grindrod, Jeremy Meiss, Josh Wulf, and Ted Neward.

Recently Corey Quinn from LastWeekInAWS wrote an article that made me think “Nobody Cares About the Operating System Anymore”. Please have a look at it! I like the idea that nobody cares about where their application runs. Developers only want them running.
I am one of the maintainers for the Tinkerbell project. A bare metal workflows engine that heavily relies on containers and Docker to get its work done. It tries to find an answer for a reasonable question: how do we manage rooms of pieces of hardware? More in practice, how can we bring an API on top of everybody’s data centers?
Containers are the abstraction we decided to use when running reusable code (that we call actions) in somebody else’s hardware. Mainly because distribution, packaging, and runtime are solved issues. Everyone knows how to build, push and run a container.
I think this scenario compares well with the story Corey highlighted. Operating systems are an established, well-known abstraction for the majority of the use cases.
The lifecycle of a bare metal server can be summarised as follows:
Today, we are announcing the beta of Cloudflare Images: a simple service to store, resize, optimize, and deliver images at scale.
In 2018, we launched Stream to provide a single product that could be used to store, encode, and deliver videos. With Cloudflare Images, we are doing for images what Stream did for videos. Just like Stream, Cloudflare Images eliminates the need to think about storage buckets, egress costs, and many other common problems that are solved for you out of the box. Whether you are building an ecommerce platform with millions of high-res product pictures and videos or a new app for creators, you can build your entire media pipeline by combining Cloudflare Images and Stream.
Any time you are building infrastructure for image storage and processing, there are four fundamental questions you must answer:
Cloudflare Images has a straightforward set Continue reading
While MANRS has gone from strength to strength since its beginning in 2014, gaining attention, interest, and credibility from network operators worldwide, for the initiative to be sustainable and impactful in the long run there should be a stronger sense of ownership by the community. MANRS is an industry-led initiative whose participants set and develop […]

Starting today, your team can create a private network on Cloudflare’s network. Team members click a single button to connect to private IPs in environments that you control. Cloudflare’s network routes their connection through a data center in one of over 200 cities around the world. On the other side, administrators deploy a lightweight software connector that replaces traditional VPN appliances.
Cloudflare’s private network combines IP level connectivity and Zero Trust controls. Thick clients like RDP software, SMB file viewers, or other programs can connect to the private IPs already in use in your deployment without any additional configuration. Coming soon, you’ll be able to layer additional identity-based network-level rules to control which users, from which devices, can reach specific IPs.
We are launching this feature as a follow-up to Cloudflare’s Developer Week because we are excited to give your development team, and your entire organization, a seamless platform for building and connecting your internal resources. We built this solution based on feedback from customers who want to move to a Zero Trust model without sacrificing some of the convenience of a private network.
We’re excited to give any team the ability to run their internal network on Cloudflare’s global Continue reading
Scott submitted an interesting the comment to my Does Unequal-Cost Multipath (UCMP) Make Sense blog post:
How about even Large CLOS networks with the same interface capacity, but accounting for things to fail; fabric cards, links or nodes in disaggregated units. You can either UCMP or drain large parts of your network to get the most out of ECMP.
Before I managed to write a reply (sometimes it takes months while an idea is simmering somewhere in my subconscious) Jeff Tantsura pointed me to an excellent article by Erico Vanini that describes the types of asymmetries you might encounter in a leaf-and-spine fabric: an ideal starting point for this discussion.

There are lots of reasons to get educated about cloud networking. You might: Be responsible for connecting end users to numerous cloud services Have to link an application in Cloud A to services and data in Cloud B Support a hybrid application that has one foot in your DC and another in AWS, Azure, or […]

Azure VMware Solution (AVS) is a VMware–validated private cloud solution, managed and maintained by Azure. It runs on dedicated, bare-metal Azure infrastructure. AVS allows customers to manage and secure applications across both VMware environments and Microsoft Azure resources with a consistent operating framework. It supports workload migration, VM deployment, and Azure service consumption.
As AVS private cloud runs on an isolated Azure environment, by default it is not accessible from Azure or the Internet. Users can use either ExpressRoute Global Reach (i.e., from on-prem) or a jump box (i.e., on an Azure VNet) to access AVS private cloud. This means AVS workload VMs are confined within AVS private cloud and not accessible from the Internet. If customers want to make AVS Private Cloud resources, such as web servers, accessible from the Internet, Public IP needs to be deployed. There are a couple of ways to do this: (1) Destination NAT or DNAT via Azure Virtual WAN/Azure Firewall; and (2) Azure Application Gateway. This article focuses on DNAT with Azure Virtual WAN/Azure Firewall.
Zero Trust Architecture (ZTA) is a security point of view that has gathered enough momentum in 2020 and 2021 to frequently appear in marketing literature. The big idea of zero trust in network computing is roughly, “I confidently know who you are and have applied an appropriate security policy, but I still don’t trust you.”
My understanding of ZTA continues to evolve. This post represents my understanding today, with an emphasis on what ZTA means for network engineers.
At first glance, zero trust sounds mostly like a firewall policy. Of course I don’t trust you. That’s why we apply all these filtering rules to the VPN tunnel, network interface, etc. Yes, but simple filtering implies a level of trust. The trust comes in the assumption that if you get through the filter, what you’re saying is trustworthy.
Zero trust does away with that assumption. For example…

With just over a month to go before DockerCon LIVE 2021, we’re thrilled to announce our first round of speakers. We have returning favorites and compelling new first time speakers to round out your DockerCon experience.
We received hundreds of amazing speaker proposals which made it difficult to select just a few. We set up a small team this year composed of seven Docker staff members and three Docker Captains to diligently review each proposal and deliberate once a week. We have more speakers and sessions to announce so stay tuned.
Remember, if you haven’t registered for DockerCon, please make sure to do so now to get an early peak at the conference website.
