Python Pieces – Working with etcd

Ah ha! Surprise – I’ve decided that in addition to the blog posts on MPLS and ExaBGP that I might as well start up a third series. Well – that’s not entirely true – but instead of trying to mix all sorts of details about Python into the blog posts, I thought I might split out some of the larger pieces. So Im starting a new series called “Python Pieces” where I’m going to pick one module, concept, or whatever else I decided warrants a post and talk about how to use it. Then – if/when I use that in one of my other posts – you’ve got a handy reference and starting point. I hope this makes the other posts less “all over the place” but we’ll see.

So – in my first edition of Python Pieces we’re going to talk about working with etcd from Python. For those of you that don’t know what etcd is – it’s a pretty popular key value store that’s used with lots of the more recent projects (Kubernetes comes to mind). What’s likely more important about etcd though is that it’s capable of being a distributed key value store which makes it Continue reading

Juniper Firewall Filters

Firewall filters are similar to access control lists (ACLs). Firewall filters are stateless and inspect each packet individually. Because they are stateless traffic must be allowed in both directions. Configuration Routing policies and firewall filters have a common structure. ...continue reading

Juniper Routing Policy

Junos routing policy allows an administrator to alter the default behaviour of a routing protocol. All routing protocols try to determine the best path to a destination based on the protocols definition of the best "metric". The Junos routing policy framework allows an...continue reading

Juniper Junos

Junos is the name of the operating system that is used to manage Juniper network devices. Fun fact Junos is built on a base of FreeBSD and is designed to be modular and secure while providing a uniform user interface across all platforms. Junos Features Common Code Base The...continue reading

Juniper Protocol Independent Routing

Juniper protocol-independent routing covers IP routing components such as static routes and the various route tables within Junos that are not particular to any dynamic routing protocol. Routing Table The RE holds a copy of all routes from all protocols in its routing table....continue reading

IoT roundup: Outer space, the building is getting smart, and trucking

The classical view of an IoT deployment is relatively centralized – a company wires sensors to important equipment, the sensors send data back to edge gateways, and the gateways do some limited processing of that data and then send it back to the cloud or to the data center. It’s not simple, but it’s easy enough to understand the principles.Some, however, recognize that vastly different architectures for the IoT are possible, including Fleet Space Technologies, a startup that earlier this month announced that it had reached a million device signups for its ambitious satellite-based IoT edge system, which it’s calling Project Galaxy.To read this article in full, please click here

Cloudflare Registrar at three months

We announced Cloudflare Registrar in September. We launched the product by making it available in waves to our existing customers. During that time we gathered feedback and continued making improvements to the product while also adding more TLDs.

Staring today, we’re excited to make Cloudflare Registrar available to all of our customers. Cloudflare Registrar only charges you what we pay to the registry for your domain and any user can now rely on that at-cost pricing to manage their domain. As part of this announcement, we’d like to share some insights and data about domain registration that we learned during the early access period.

One-click DNS security makes a difference

When you launch your domain to the world, you rely on the Domain Name System (DNS) to direct your users to the address for your site. However, DNS cannot guarantee that your visitors reach your content because DNS, in its basic form, lacks authentication. If someone was able to poison the DNS responses for your site, they could hijack your visitors' DNS requests.

The Domain Name System Security Extensions (DNSSEC) can help prevent that type of attack by adding a chain of trust to DNS queries. When you enable DNSSEC Continue reading

What is Linux? Everything you need to know about the open-source operating system

Linux is a tried-and-true, open-source operating system released in 1991 for computers, but its use has expanded to underpin systems for cars, phones, web servers and, more recently, networking gear.Its longevity, maturity and security make it one of the most trusted OSes available today, meaning it is ideal for commercial network devices as well as enterprises that want to use it and its peripherals to customize their own network and data center infrastructure.[ Also see Invaluable tips and tricks for troubleshooting Linux. ] That in turn makes Linux skills highly sought after by IT hiring managers. For example, many of the new technologies associated with DevOps, such as containers, infrastructure, and SDN controllers, are built on Linux.To read this article in full, please click here

Google on-premises Kubernetes solution enters beta

Google this week announced the beta version of its Cloud Services Platform, an on-premises software product that allows enterprises to deploy Google’s Kubernetes Engine inside their own data centers.Google announced CSP last July at its Cloud Next conference. Enterprises can build an in-house duplicate of Google’s cloud service to deploy Kubernetes containers to build, test, and deploy, and then move parts or all of it to the public Google cloud, all while managing it with centralized software.To read this article in full, please click here

Arm introduces Neoverse high-performance CPUs for servers, 5G

There have been some interesting developments in the Arm-as-a-server processor field, from Cavium’s success to Amazon offering much cheaper instances on its home-brew Arm processors. But now Arm Holdings itself is getting into the fray, and it's offering is a whopper.Last October, Arm announced the Neoverse platform designed specifically for cloud computing and edge network environments. This week it revealed the Neoverse N1 and E1 platforms, and they are impressive. Usually when Intel and AMD introduce new server chips, they are basically the same chips with faster clocks and more cores. But these two chips are very different in design and meant for different use cases.To read this article in full, please click here
