Worth Reading: AMD and the Infinity Fabric

Starting with AMD’s Ryzen desktop processor and Epyc server architecture, AMD will implement their scalable Infinity Fabric across all its SoC and MCM products. Think of Infinity Fabric as a superset of HyperTransport, AMD’s previous socket-to-socket interconnect architecture, now managed by the HyperTransport Consortium. Infinity Fabric is a coherent high-performance fabric that uses sensors embedded in each die to scale control and data flow from die to socket to board-level. —The Next Platform

Beware of companies claiming products have AI capabilities

Software companies are exploiting the current artificial intelligence (AI) craze by exaggerating the scope and capabilities of AI in their products, according to a report from Gartner. Gartner tracks product marketing hype with a tool it calls the Hype Cycle, measuring the growth and decline of products as they mature. It calls the process of overhyping AI "AI washing," similar to the way the term “greenwashing” was used to describe exaggerated claims of environmental-friendliness in various products or practices. Gartner said more than 1,000 vendors say their products employ AI, but many are "applying the AI label a little too indiscriminately." And it has happened fast.To read this article in full or to leave a comment, please click here

Context From The People

Are you ready for the flood of context-based networking solutions? If not, it’s time to invest in sandbags. After the launch of Cisco’s Intuitive Network solution set at Cisco Live, the rest of the context solutions are coming out to play. Granted, some of them are like Apstra and have been doing this for a while. Others are going to be jumping on the bandwagon of providing a solution that helps with context. But why are we here and why now?

Creating Context

The truth is that we’ve had context in the network for decades now. It’s not a part number that we can order from a vendor. It’s not a command that we type into the CLI to activate. In fact, it’s nothing that you can see at all right now, unless there’s a mirror handy.

The context in networks has been provided by people for as far back as anyone can remember. You do it every day without consciously realizing it. You interpret error messages and disregard those that aren’t important. People know how to program VLANs correctly to segment traffic in certain ways. Security context, application context, and more are delivered by breathing, thinking humans.

We have Continue reading

Stuff The Internet Says On Scalability For July 21st, 2017

Hey, it's HighScalability time:

Afraid of AI? Fire ants have sticky pads so they can form rafts, build towers, cross streams, & order takeout. We can CRISPR these guys to fight Skynet. (video, video, paper)

Docker Community Spotlight: Adina-Valentina Radulescu

Adina-Valentina Radulescu, a DevOps/Integration Engineer for Pentalog Romania, has been organizing meetups for not one but two meetup groups.

In February of last year, Adina founded Docker Brasov and Docker Timisoara, and has since done an amazing job creating and fostering a sense of belonging in her community. This month, we’re happy to shine the community spotlight on Adina to learn more about her Docker story.

Tell us about your first experience with Docker.

The first time I heard about Docker was back in 2014. I played around with Docker and I was impressed with the simplicity of integration so I wanted to learn more. I was able to attend DockerCon EU in 2015 in Barcelona where I completed some labs and attended the talks to learn as much as I could about Docker. It was a powerful feeling.

Why did you start Docker Brasov and Docker Timisoara?

I wanted to have a Docker sharing exchange experience when I get back in Romania. I relocated from Timisoara to a beautiful mountain city, Brasov. In Timisoara, I knew people and companies. In Brasov, I knew almost no one. This is why I decided to start the two groups so I Continue reading

Worth Reading: Is Decentralized Storage Sustainable?

There are many reasons to dislike centralized storage services. They include business risk, as we see in le petit musée des projets Google abandonnés, monoculture vulnerability and rent extraction. There is thus naturally a lot of enthusiasm for decentralized storage systems, such as MaidSafe, DAT and IPFS. —DHSR

I am going to talk about the OSPF show commands in this article on different vendors which includes Cisco, Juniper, Huawei, HP and Arista Networks. These commands are working as per the device you have. Please let me know if you knew any other commands in general for OSPF in different platforms which includes Cisco, Juniper, Huawei, HP and Arista Networks.

How to use Cloudflare for Service Discovery

Cloudflare runs 3,588 containers, making up 1,264 apps and services that all need to be able to find and discover each other in order to communicate -- a problem solved with service discovery.

You can use Cloudflare for service discovery. By deploying microservices behind Cloudflare, microservices’ origins are masked, secured from DDoS and L7 exploits and authenticated, and service discovery is natively built in. Cloudflare is also cloud platform agnostic, which means that if you have distributed infrastructure deployed across cloud platforms, you still get a holistic view of your services and the ability to manage your security and authentication policies in one place, independent of where services are actually deployed.

How it works

Service locations and metadata are stored in a distributed KV store deployed in all 100+ Cloudflare edge locations (the service registry).

Services register themselves to the service registry when they start up and deregister themselves when they spin down via a POST to Cloudflare’s API. Services provide data in the form of a DNS record, either by giving Cloudflare the address of the service in an A (IPv4) or AAAA (IPv6) record, or by providing more metadata like transport protocol and port in an SRV record.

Configuring Private VLANs on Juniper Switches

Thanks for the huge support on all my previous articles. Today I am going to talk about the Private VLANs configuration on the Juniper Switches. Earlier I wrote a article where i talk about the basics of the Private VLANs and the vendors supported to Private VLANs. If you want to have a look on that article, please go through the below mentioned link for the Private VLANs

Basics of Private VLANs

I am sure after reading the above article you will come to know about the basics of the Private VLANs. In this article I am going to cover the Configurational part of the Private VLANs on Juniper Switches, as it is demanded by some of the candidates on the blogs.

I will soon come up the configuration and the topology for the Private VLANs on Cisco and Huawei as well in another article.

A lot of people asking me about the VLANs, before starting with the configuration of the Private VLANs, let me quickly go through the VLANs and Private VLANs.

VLANs : Virtual Local Area Networks
VLANs is the way to partition the various Layer 2 network with in one Local Area Network which simply means that Continue reading

Cisco N1000v Switches

A cisco vswitch that can be used instead of the default VMware DvS to have a similar environment to that of Cisco physical NXOS switches. The control and packet communication can either be carried over VLANs in Layer2 mode or IP addresses in Layer3 mode. The default and Cisco recommended solution is L3 mode.
