The Week in Internet News: Covert Social Media Campaign Champions Military Rulers

The Internet as warfighting tool: Military rulers in Sudan and other countries are paying “Internet warfare” firms to develop social media campaigns to praise their leadership, the New York Times reports. The story highlights a social media company called New Waves, run by a former member of the Egyptian military and a self-described “researcher on Internet wars.”

Internet warfare, part 2: Meanwhile, a “virtual army” from mainland China has focused on recent protests in Hong Kong, with social media posts boosting government interests, the South China Morning Post writes. New recruits to the nationalist Diba group are taught how to use VPNs and circumvent the government firewall to reach the “battlefield” – social media pages and websites normally banned.

Protestors strike back: The Hong Kong protestors had their own Internet-related tactics, QZ.com reports. In response to threats of Internet shutdown, protestors began to use Bluetooth-based mesh networking technologies, allowing them to communicate through a network of devices that are linked locally, rather than over an Internet connection.

Consuming Pre-Existing AWS Infrastructure with Cluster API

All the posts I’ve published so far about Kubernetes Cluster API (CAPI) assume that the underlying infrastructure needs to be created. This is fine, because generally speaking that’s part of the value of CAPI—it will create new cloud infrastructure for every Kubernetes cluster it instantiates. In the case of AWS, this includes VPCs, subnets, route tables, Internet gateways, NAT gateways, Elastic IPs, security groups, load balancers, and (of course) EC2 instances. But what if you didn’t want CAPA to create AWS infrastructure? In this post, I’ll show you how to consume pre-existing AWS infrastructure with Cluster API for AWS (CAPA).

Why would one not want CAPA to create the necessary AWS infrastructure? There are a variety of reasons, but the one that jumps to my mind immediately is that an organization may have established/proven expertise and a process around the use of infrastructure-as-code (IaC) tooling like Terraform, CloudFormation, or Pulumi. In cases like this, such organizations would very likely prefer to continue to use the tooling they already know and with which they are already familiar, instead of relying on CAPA. Further, the use of third-party IaC tooling may allow for greater customization of the infrastructure than CAPA Continue reading

Replacing a Network Element Config System with Git

In this post I’ll explore replacing the heart of a network operating system’s configuration mechanism with the software developers take on version control. It can be argued that network operating systems, or at least good ones, already have a version control system. It’s that very system that allows you to roll back and carry out operations like commit-confirmed. More specifically, this is a version control system like Git but not specifically git.

As my day job rotates around Junos, I’ll concentrate on that. So why would anyone want to rip out the heart of Junos and replace it with a git backed directory full of configuration snippets? Software developers and now automation skilled engineers want the advantages of being able to treat the network like any other service delivering node. Imagine committing human readable configuration snippets to a network configuration directory and having the network check it out and do something with it.

Junos already has a configuration engine capable of rollbacks and provides sanity through semantic and syntax commit time checks. Mgd (the service you interact with) provides mechanisms to render interfaces through YANG models and generates the very configuration tree you interact with. You could say mgd takes Continue reading

Experiences with approximating queries in Microsoft’s production big-data clusters

Experiences with approximating queries in Microsoft’s production big-data clusters Kandula et al., VLDB’19

I’ve been excited about the potential for approximate query processing in analytic clusters for some time, and this paper describes its use at scale in production. Microsoft’s big data clusters have 10s of thousands of machines, and are used by thousands of users to run some pretty complex queries. These clusters are in high demand and approximate query processing both saves their users time and lightens the overall load on the cluster.

What’s especially nice about this paper is that we get a glimpse into the practical adoption issues of persuading users that it’s ok to approximate too.

We have implemented support for query time sampling in production big-data clusters at Microsoft: these clusters consist of tens of thousands of multi-core, multi-disk servers and are used by developers from many different businesses including Bing, Azure, and Windows. In total, the clusters store a few exabytes of data and are primarily responsible for all of the batch analytics at Microsoft.

Approximate query support

Control over approximation is put into the hands of the user via extensions to the query language. In particular, support for expressing sampling requirements Continue reading

Why we cannot live without a Telco Cloud, and how does one build one?

There are a more mobile phone connections (~7.9 billion) than the number of humans (~7.7 billion) colonising this planet.

Let me explain.

Clearly, not every person in the world has a mobile device. Here we’re talking about mobile connections that come from people with multiple devices (dual SIMs, tablets) and other integrated devices like cars, and other smart vehicles, and of course the myriad IOT devices. I don’t have to go too far — my electric 2 wheeler has a mobile connection that it uses to cheerfully download the updated firmware version and the software patches every now and then.

While the global population is growing at 1.08% annually, the mobile phone connections are growing at 2.0%. We will very soon be outnumbered by the number of mobile subscriptions, all happily chatting, tweeting and in general sending data over the network. Some of it would need low latency and low jitter, while some may be more tolerant to the delays and jitter.

What’s the big deal with mobile connections growing?

Well, historically most people have used their mobile phones to talk; to catch up on all the gossip on your neighbours and relatives.

Not anymore.

Two AMD Epyc processors crush four Intel Xeons in tests

Tests by the evaluation and testing site ServeTheHome found a server with two AMD Epyc processors can outperform a four-socket Intel system that costs considerably more.If you don’t read ServeTheHome, you should. It’s cut from the same cloth as Tom’s Hardware Guide and AnandTech but with a focus on server hardware, mostly the low end but they throw in some enterprise stuff, as well.ServeTheHome ran tests comparing the AMD Epyc 7742, which has 64 cores and 128 threads, and the Intel Xeon Platinum 8180M with its 28 cores and 56 threads. The dollars, though, show a real difference. Each Epyc 7742 costs $6,950, while each Xeon Platinum 8180M goes for $13,011. So, two Epyc 7742 processors cost you $13,900, and four Xeon Platinum 8180M processors cost $52,044, four times as much as the AMD chips.To read this article in full, please click here
