Beware XML-to-JSON Information Loss (Junos with Ansible)
When you want to transport a complex data structure between components of a distributed system you’re usually using a platform-independent data encoding format like XML, YAML, or JSON.
XML was the hip encoding format in days when Junos and Cisco Nexus OS was designed and lost most of its popularity in the meantime due to its complexity (attributes, namespaces…) that makes it hard to deal with XML documents in most programming languages.
JSON is the new cool kid on the block. It’s less complex than XML, maps better into data structures supported by modern programming languages, and has decently fast parser implementations.

Networking and Security are Converging. Are You Ready?
Once you've built a networking solution built on the foundation of security-driven networking—one that weaves security and networking functionality into a single system—you're ready for anything.Cisco adds to its Nexus data-center-management software
Cisco has added support for traditional network environments to the company’s recently available data center-management console.
Introduced in October, Cisco’s Nexus Dashboard melds a number of Cisco’s on-premises, cloud and hybrid fabric-management tools into a single interface to administer application lifecycles from provisioning to maintenance and optimization.
The idea is that the dashboard provides a central platform for data center-operation applications to simplify the operation and management of the applications while reducing the infrastructure overhead to run them, according to Cisco.
Qualcomm Probably Not Pursuing Arm Servers With Nuvia Purchase
Hot on the heels of our overview of the state of the Arm server CPU landscape yesterday, chip maker Qualcomm, which dabbled in Arm server chips a few years back, announced that it was acquiring startup Nuvia for its Arm chips and design team. …

Managers Must Prep Their Teams For Kubernetes – Video
If the boss demands a Kubernetes deployment, and flies in a team of consultants to get the project off the ground, what should the IT staff be prepared for once the consultants depart? That’s the question in this excerpt of Day Two Cloud podcast “Why Kubernetes Is Wrong For You.” You can listen to the […]

Day Two Cloud 080: Multi-Cloud Isn’t A Myth – We Have Proof
Is multi-cloud real? Some say no, but others know the reality of multi-cloud because they are living it every day. One such human is William Collins, and he joins us to talk through some actual multi-cloud use cases.Day Two Cloud 080: Multi-Cloud Isn’t A Myth – We Have Proof

Top Developer Trends for 2021
The year 2020 will go down in the history books for so many reasons. For Docker, despite the challenges of our November 2019 restructuring, we were fortunate to see 70% growth in activity from our 11.3 million monthly active users sharing 7.9 million apps pulled 13.6 billion times per month. Thank you, Docker team, community, customers, and partners!
But with 2020 behind us it’s natural to ask, “What’s next?” Here in the second week of January, we couldn’t be more excited about 2021. Why? Because the step-function shift from offline to online of every dimension of human activity brought about by the global pandemic is accelerating opportunities and challenges for development teams. What are the key trends relevant to development teams in 2021? Here are our top picks:
The New Normal: Open, Distributed Collaboration
While already a familiar teamwork model for many open source projects and Internet companies, the global pandemic seemingly overnight drove all software development teams to adopt new ways of working together. In fact, our 2020 survey of thousands of Docker developers about their ways of working found that 51% prefer to work mostly remote and only sometimes in an office if/when given Continue reading
A Name Resolver for the Distributed Web
The Domain Name System (DNS) matches names to resources. Instead of typing 104.18.26.46 to access the Cloudflare Blog, you type blog.cloudflare.com and, using DNS, the domain name resolves to 104.18.26.46, the Cloudflare Blog IP address.
Similarly, distributed systems such as Ethereum and IPFS rely on a naming system to be usable. DNS could be used, but its resolvers’ attributes run contrary to properties valued in distributed Web (dWeb) systems. Namely, dWeb resolvers ideally provide (i) locally verifiable data, (ii) built-in history, and (iii) have no single trust anchor.
At Cloudflare Research, we have been exploring alternative ways to resolve queries to responses that align with these attributes. We are proud to announce a new resolver for the Distributed Web, where IPFS content indexed by the Ethereum Name Service (ENS) can be accessed.
To discover how it has been built, and how you can use it today, read on.
Welcome to the Distributed Web
IPFS and its addressing system
The InterPlanetary FileSystem (IPFS) is a peer-to-peer network for storing content on a distributed file system. It is composed of a set of computers called nodes that store and relay content using a common Continue reading
Developing NetBox Plugin – Part 3 – Adding search panel
Welcome to part 3 of my tutorial walking you through process of developing NetBox plugin. In part 2 we added basic web UI views to our BgpPeering plugin. In this post we'll add search panel to list view to allow us to search/filter Bgp Peering objects.

Introduction
List view we created for displaying all Bgp Peering objects in one place is very useful. However it will become difficult to find items of interest once we have more than 30-50 objects. For that purpose we should add means of filtering objects to the ones that meet certain criteria.
Other objects in NetBox already have filtering functionality and use search panel located to the right of object tables. Continue reading
