1. Reaction: Centralization Wins – Rule11 Reader
Russ White examines the notion that the Internet, which was initially designed as a decentralized system, is becoming more centralized. There are pros and cons with this change. For example, centralization may be useful when resources are scarce. But centralization also enables one or a handful of organizations to accrue power, and then use that power to do things such as suppress innovation, artificially raise prices, and otherwise attempt to entrench and extend their power.
“The question is: will we reach full centralization? Or will some new idea—a new/old technology that organizes information in a different way—disrupt the coalescing centralized powers?
The answer to this question impacts what skills you should be learning now, and how you approach the rest of your career (or life!). A lot of your career rests not just on understanding the command lines and hardware, but reaching beyond these into understanding the technologies, and even beyond the technologies to understand the way organizations work.”
2. Using Terraform to Up Your Automation Game: Multi-Environment/Multi-Region – Maentz.net
Gabe Maentz has a detailed blog series on using Terraform to build VPCs in AWS and deploy infrastructure. This post is part three, but Gabe has thoughtfully included links to parts one and two so you can easily get the whole series. Check it out!
3. Need better wireless coverage? Try a different antenna! – The IT Rebel
Warehouse WLAN design can get tricky. You’ve got to cover cavernous spaces, you’re dealing with shelving and inventory that can interfere with signals, and floor plans may change. The IT Rebel looks at three design options, and then drills into the benefits of specialized antennas that may be the fix you’re looking for, whether for a warehouse or another design project.
4. DNSSEC and DNS over TLS – ISP Column
The prolific Geoff Huston responds to the assertion that DNS over Transport Layer Security (DoT) is a viable replacement for DNSSEC. His take? We need both.
This is a long blog, but if you need a refresher on DNSSEC and DoT and then a useful comparison of the two, this read is worth your time.
5. Announcing VMware vSphere Platinum, the Evolution of vSphere Security – vMiss
VMworld 2018 in Las Vegas wrapped up this week, and VMware made a few noteworthy announcements. One is the bundling of vSphere with VMware’s AppDefense software. vMiss offers some perspective on this announcement and shares some perspective on the news.
6. LinkedIn Message Generator – Duber
Have a little fun with this parody site that automatically generates a message from a tech recruiter.
1. Can a script kiddie pwn your SD-WAN? Better check the config, friend – The Register
Richard Chirgwin at The Register writes: “Russian researchers armed with Shodan and Censys have identified nearly 5,000 SD-WANs with vulnerable management interfaces.
It won’t surprise anyone, The Register suspects, that most of the problems the three researchers (Denis Kolegov and Antony Nikolaev of Tomsk State University, and DarkMatter’s Sergey Gordeychik) discovered are down to “outdated software and insecure configuration”.”
2. T-Mobile/Sprint merger will bring higher prices, small carriers tell FCC – Ars Technica
Jon Brodkin at Ars Technica writes “T-Mobile USA’s proposed acquisition of Sprint would harm competitors and consumers, particularly in rural America, lobby groups for small carriers say.”
3. The Scunthorpe Problem, And Why AI Is Not A Silver Bullet For Moderating Platform Content At Scale – TechDirt
Cathy Gellis at TechDirt writes: “Maybe someday AI will be sophisticated, nuanced, and accurate enough to help us with platform content moderation, but that day isn’t today.”
4. Introduction to Infrastructure as Code – Network Computing
Brett Johnson at Network Computing writes “Small misconfigured settings plague many IT environments, impacting security and stability. Infrastructure as code lets you apply a consistent configuration to a broad range of endpoints.”
5. Are DIY Telco Networks DOA? If True, Great for VMware – Light Reading
Mitch Wagner at Light Reading writes: “Service providers seem to be abandoning their dream of building DIY networks from best-of-breed parts, just as VMware is coming up to speed with an all-in-one networking package for telcos, says Roz Roseboro, Heavy Reading principal analyst, cloud infrastructure and management.”
