1. Figuring Out AWS Networking – IPSpace
Are you curious about how Amazon’s AWS networking works? You should be–a good deal of it is hidden from customers behind layers of abstraction and automation. But it’s not entirely a black box.
Ivan Pepelnjak advises approaching AWS networking like a science experiment: start with a hypothesis, then set up a VPC and run tests. Measure the outcome, check it against your original supposition, then rinse and repeat.
2. CCIE Progress Update – 0x2142.com
A lot of certification posts talk about how the writer achieved the cert: the materials they used, study techniques they employed, and so on. Matt Schmitz set out to take the CCIE exam earlier this year, but missed his own deadline. In this post he explains what happened, and how he’s going to stay on track to try again.
3. The Littlest Datacenter Part 2: Internet and Firewalls – TimClevenger.com
Tim Clevenger is documenting a small IT buildout (two racks) at a new site of his employer’s. The most recent installment delves into his choice of hardware to run a pfSense firewall. He goes through the box specs and other details, including why he didn’t just run the firewall as a VM on the application servers.
4. Moving Your Fleet from AWS to AZURE with Terraform – Maentz.net
Gabe Maentz is writing an ongoing tutorial series about Terraform, an infrastructure automation tool. In the latest edition he covers how to use Terraform to move resources from one public cloud to another–in this case, from AWS to Azure.
5. Network Horizons 2018 – 2019: Available Now – Network Architecture 2020
Alex Marcham, who blogs at Network Architecture 2020, has just published a new book on important network trends and emerging technologies.
Alex writes “This book is intended to be a guide to the key developments to keep an eye on in the near future. Think of it as a filter which you can use on the unending flow of information within these industries, to make sure you spend your time as effectively as possible to benefit yourself, your network and your business.”
1. Investigating Implausible Bloomberg Supermicro Stories – Serve The Home
Patrick Kennedy, writing at the Web site Serve The Home, does a detailed teardown of Bloomberg’s claims about a malicious chip implanted on Supermicro motherboards, casting further doubt on the accuracy of the story. This post takes each of Bloomberg’s major claims and analyzes them closely for technical flaws. It’s an impressive piece of work.
It’s also very long. You’ll want to block off a little time if you plan to go through the whole thing.
2. Oracle OpenWorld 2018 – making the cloud friendly for enterprises that distrust cloud – Diginomica
Kurt Marko, writing at Diginomica, has a detailed post about the latest offerings from Oracle’s annual OpenWorld showcase, as well as some smart analysis of Oracle’s cloud efforts.
Kurt writes “Unlike AWS and Google Cloud, Oracle has focused on building an environment to accommodate legacy workloads and that minimizes the disruption in migrating database-backed applications from on-premise to cloud deployments. As such, its Cloud 2.0 looks more like Cloud 0.5: a great stepping stone from enterprise data centers to cloud managed services.”
3. An Alternative History Of Silicon Valley Disruption – Wired
Wired reviews three recent books that critique the myths surrounding high-tech companies and their rise to power. While the myth-makers of Silicon Valley insist that disruption and bold innovation enabled tech behemoths to out-evolve older, more staid companies, these books dispel the mirage of execptionalism.
“The authors argue that tech companies conquered the world not with software, but via the usual route to power: ducking regulation, squeezing workers, strangling competitors, consolidating power, raising rents, and riding the wave of an economic shift already well underway.”
4. Should a self-driving car kill the baby or the grandma? Depends on where you’re from – Technology Review
Karen Hao, writing at Technology Review, reports on a new study published in Nature that analyzes the results gathered from the Moral Machine, an experiment from MIT Media Labs that asked people all over the world to determine the choices an autonomous vehicle should make when presented with life-and-death situations.
Results vary from country to country, and across the economic spectrum.
5. Tech world mulls threat as new round of US China trade tariffs looms – The Register
Paul Kunert of The Register writes that to date the trade war has “…largely impacted networking kit, with Cisco and Juniper both upping their prices in the channel which are then passed down the chain to the end user. Cisco prices, as we exclusively revealed, went up on average by 7.8 per cent and Juniper has said punters can expect a 4 per cent hike on “affected products“.
