First, Docker transformed how we ran applications. Then, Kubernetes changed how we managed containers. Now, the open-source project Istio is building on both to add a network service mesh.
Istio is built on the open-source Envoy proxy. This service mesh enables microservices sharing distributed applications to communicate and work with one another. As Matt Klein, Envoy’s creator wrote, Istio provides modern microservice and cloud-native applications with a “unified control plane that ties the pieces together in a coherent way.”
Istio also enables DevOps. In a soon-to-be-released blog, Google Cloud‘s Eric Brewer, VP Infrastructure, and Eyal Manor, VP of Engineering, point out that Istio provides vital DevOps framework “such as a common system for monitoring, logging, authorization, and billing.”

Brewer and Manor go on: “You need tools to manage the collection of microservices, and to ensure consistent policies across them. More importantly, these policies need to be decoupled from the individual services, so that they can be more uniform and updated independently of the services.”
Istio does this at the network level. By working over the network, Istio makes it easy to integrate microservices with load balancing, service-to-service authentication, monitoring, and more, with no changes to the underlying code.
Brewer and Manor continue: “Istio offers visibility in the form of telemetry for monitoring and logs for your services, plus security by giving each service a strong identity based on its role, as well as enabling encryption by default. With that core functionality place, Istio can also be the basis for higher-level services, e.g., helping to enforce network security policies, or controlling software rollouts through canary deployments.”
This, in turn, means, “Istio also ensures a proper decoupling between development and operations, allowing operations teams to change the behavior of the system without actually changing the source code.”
Thus, Brewer and Manor said this decoupling of development and operations logic that Istio provides accomplishes two things: It allows your developers to focus on writing business logic, not infrastructure (thus making them more productive), and it gives your operations teams the tools they need to run your applications and services more reliably.

Istio has already reached its 1.0 release. And, now it’s being deployed by such users as Descartes Labs, eBay, and AutoTrader UK. “Istio was a missing piece in the Kubernetes ecosystem. Kubernetes gave us the ability to distribute an application, but Istio gave us the ability to understand the application,” said Tim Kelton, a Descartes Labs co-founder, in a statement.
Google is pushing to bringing more users to Istio. Istio will be made available for Google Cloud users on Google Kubernetes Engine (GKE) in beta in December. On GKE, Istio layers a service mesh on your existing GKE clusters, and gathers telemetry on their containers. This data is then sent to Stackdriver or Prometheus. With these, you can monitor your Kubernetes-based microservices’ traffic, error rates, and latencies.
Google’s not the only company betting Istio is about to become important. IBM, Red Hat, and VMware are also working on improving the open-source network service mesh. It may well be that Istio may be an important part in IBM’s Red Hat post-acquisition hybrid-cloud plans.
Indiana Is The First State To Sue TikTok Over Child Safety Worries
To tech-savvy and/or historically informed readers, the widespread concern about TikTok in the U.S. might smack of earlier moral panics. As mental health nonprofit Take This reports, it’s a matter of record that social media, video and tabletop games, clothing choices, music genres, and virtually anything else enjoyed by the young have been excoriated by American elders on one moral basis or another.
At the same time, serious questions have been raised about the safety of TikTok as a platform. We’ve reported in the past about the successes and failures of TikTok’s content moderation, from its largely hands-off, algorithmic approach to managing content to the borderline unethical treatment experienced by the human moderators the platform does possess. Content capable of generating severe psychological trauma in adult professional content managers certainly shouldn’t be emerging in children’s feeds.
Moderation and data security are also inescapably entwined. Hands-off moderation doesn’t just threaten the possibility of traumatic content in users’ feeds; it allows for sharing media at least some users are likely to see as unethical if not illegal. Add that to the documented pressures that Chinese law puts on social media platforms and it starts to seem like the Indiana lawsuit, right or wrong, at least has some kind of grounding.
Still, TikTok has answered critics and survived plenty of tough talk from the previous presidential administration. Whether it can continue to do so will depend both on the commitment of the platform’s user base and its ability to adapt to the requirements of American law.
How Fast Is The Electric Harley-Davidson Motorcycle Really?
According to Livewire, the ONE has some impressive speed and acceleration numbers, going from 0-60 mph in just three seconds and topping out at 110 mph. Sure, 110 mph doesn’t seem awfully fast, but Harley-Davidson motorcycles were never known for being fast. According to testing by CycleWorld, the Livewire ONE lives up to its reputation, accelerating from 0-60 mph in 3.1 seconds — a fraction of a second slower than the marketed number.
Interestingly, in terms of acceleration, the Livewire ONE is second only to the FXDR 114, which has a 0-60 mph time of only 2.5 seconds, according to Harley Davidson of Kingwood. Being quick off the line is par for the course for an electric motorcycle, though — there are no gears to cycle through, and electric motor torque is usually much higher at low RPM. The highest top speed for a production Harley-Davidson bike also goes to the FXDR 114, which tops out at a respectable 160 mph, according to Peterson’s Harley-Davidson. As far as the Livewire ONE’s 110 mph top speed, that’s par for the course for Harley-Davidson, with most everything except for the FXDR 114.
The Most Luxurious Features Of Mariah Carey’s 1.8 Million Dollar RV
Upon entering you are immediately met by a makeup station with an oversized mirror ringed by “true” makeup lights. On the opposite wall behind the seat is an offset television so the Queen of Christmas can watch her favorite program (through the mirror) while getting properly primped. Dark wood lines the floors, top and bottom (via HotCars).
This segues into a lounge with a curvy 15-foot custom couch ($7,000) and a 65″ Samsung 9000 connected to a Genelec studio-grade 5.1 surround sound system. The left side slides out 35 feet while the right slides out 25 feet to create a 600-square-foot space for her entourage.
The full gourmet kitchen includes a convection microwave, two-burner induction stove top, Sub-Zero hideaway fridge, and a $4,000 LeveLuk SD501 Platinum Kangen water system. Granite stairs lead from the kitchen to a second floor, where the roof pop-ups via hydraulics to reveal what designer RJ Anderson calls a “skyscraper on wheels” (per Daily Mail via AOL Celebrity Motor Homes).
Huge windows run down each side of the bus providing a nearly 360-degree uninterrupted panoramic view, while a 35-foot wrap-around couch seats 30 people. Not only can the lights be dimmed, but it comes with a color wheel that can turn the area into a proverbial nightclub. Big 60-inch televisions on either end of the room round out the entertainment area (via AOL Celebrity Motor Homes).
Anderson Mobile Estates also operates the 7744 Ranch, a resort outside Austin, Texas, where anyone can book a stay in a previously-owned-by-a-celebrity motor home. One of the five listed is “The Lounge.” However, a promotional video not only says it once belonged to Jennifer Lopez (not Mariah Carey) but looks precisely like Mariah Carey’s from the 2005 “Access Hollywood” segment.
Now, all we really want for Christmas is some clarification in this great camper caper.
