Kubernetes: The smart person’s guide

Kubernetes is a series of open source projects for automating the deployment, scaling, and management of containerized applications. Find out why the ecosystem matters, how to use it, and more.

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.

Ram unveils limited 1500 TRX Ignition Edition, Longhorn SouthFork, and 1500 (RED) Edition

Published

on

The 2022 Ram 1500 TRX is getting a trio of limited-edition models with custom features and unique exterior appointments. The 1500 TRX Ignition Edition, 1500 Longhorn SouthFork, and 1500 Ram (RED) Edition recently made their first appearances at the State Fair of Texas. The latter is particularly worth mentioning as Jeep, Fiat, and Ram cemented with U2 frontman Bono’s (RED) organization to fight global health crises.

“Ram customers demand even more, and our new models deliver that with a selection of exterior and interior appointments and content for greater personalization,” said Mike Koval Jr., Ram Brand Chief Executive Officer – Stellantis.

The 2022 Ram 1500 TRX Ignition has the TRX Level 2 Equipment Group. The package includes custom Ignition paint and body graphics, a panoramic sunroof, a spray-in bed liner, a bed step, cargo tie-downs, a cab-mounted LED brake light, and bespoke 18-inch machine face black wheels. Under the hood is the same 6.2-liter supercharged HEMI V8 motor pumping out 702 horsepower and 650 pound-feet of torque.

Other goodies include orange interior stitching, embroidered TRX logos on the seatbacks, copper carbon fiber trimmings, a heads-up display, and an orange center console badge. The Ram TRX Ignition starts at $91,585 (plus $1,695 destination), and only 875 units will arrive at US dealerships near the end of 2021.

Meanwhile, the 2022 Ram 1500 Longhorn SouthFork is all about luxury. It replaces the Limited Longhorn 10th Anniversary model and has an impressive lineup of standard kits like a multi-function tailgate, metal pedals, a deployable bed step, LED bed lighting, a spray-in bed liner, and a cargo divider.

It also has a Mountain Brown interior, bucket seats, suede door bolsters, and leather interior trim. The Ram 1500 Longhorn SouthFork starts at $61,620 (plus $1,695 destination) and arrives at dealerships later this year.“Buyers demand a good-looking truck with easy-to-use features. They tell us their Ram trucks are an extension of their personality, and they want to stand out from the crowd,” added Koval.

Finally, the 2022 Ram 1500 (RAM) RED Edition is available in a crew cab body style and starts at $63,250 (plus $1,695 destination). The (RAM) RED model has red RAM letters on the front grille and a (RED) badge on the center console lid. Engine choices include a 5.7-liter V8 with 395 horsepower and 410 pound-feet of torque or Ram’s 3.0-liter turbocharged EcoDiesel V6 with 260 horsepower and 480 pound-feet of torque.

2022 Honda Passport arrives with a fresh face and new rugged TrailSport trim

Published

on

Honda is fortifying its SUV lineup with the redesigned 2022 Passport five-seat crossover. The new Passport comes with an outdoorsy TrailSport trim with chunkier bumpers, a wider track, and 18-inch wheels with chunky tires. Standard across the board is a more rugged façade (derived from the Honda Ridgeline) and a mild splattering of technology updates.

Honda has yet to show the standard 2022 Passport, so let’s focus on the off-road-ready TrailSport version. “Some may not realize the true rugged, off-road capabilities of our light trucks,” said Dave Gardner, executive vice president of National Operations, American Honda Motor Co., Inc. “Now they’re getting tough, rugged looks to match, and the addition of TrailSport will further enhance the off-road capability of our vehicles in the future.”

The 2022 Honda Passport TrailSport has chunkier front and rear bumpers, a unique grille, and silver skid plates. It also has special Orange TrailSport badges on the grille and tailgate. In addition, TrailSport has a 10 millimeter wider front and rear track for a burlier stance and better stability. It also offers more room to accommodate all-new machine-finished 18-inch wheels wrapped in TrailSport-specific off-road tires.

Under the hood remains a 3.5-liter V6 engine with 280 horsepower and 262 pound-feet of torque. Power goes to a nine-speed automatic transmission driving the front wheels. However, standard in Passport TrailSport and Elite is Honda’s i-VTM4 torque-vectoring all-wheel-drive system. The drivetrain can automatically send up to 70-percent of engine torque to the rear wheels in rugged terrain. It can also send 100-percent of that torque to either the left or right rear wheels to keep you going.

All AWD Passport models have 8.1-inches of ground clearance and can tow up to 5,000 pounds when properly equipped. All trims also get 50.5 cubic feet of cargo space and a power tailgate. Passport also has under-floor storage compartments in the back to keep wet clothes and dirty boots from mingling with your precious cargo.

Meanwhile, every 2022 Honda Passport has standard Honda Sensing. The package includes a collision mitigation braking system, forward collision warning, lane-keeping assist, road departure mitigation, lane departure warning, and adaptive cruise control. Additional standard safety equipment includes LED headlights, smart entry with push-button start, a rear-seat reminder, and a rear seatbelt reminder.

Inside, the 2022 Honda Passport gets an 8-inch infotainment touchscreen with Apple CarPlay and Android Auto connectivity. Furthermore, the EX-L trim has perforated leather seats and contrasting stitching, while Passport TrailSport has amber interior ambient lighting, rubber floor mats, orange stitching. Pricing remains forthcoming, but the new Passport arrives at dealerships this winter.

Aura EV Concept is a collaboration of brilliant British minds

Published

on

The Aura EV Concept is a long-range, all-electric speedster boasting 400 to 500 miles of driving range. It may not have the supercar-styling of a Bugatti Chiron or McLaren Elva. Still, the Aura EV is more about substance than style and results from a collaboration between four British companies: BAMD Composites, Conjure, Astheimer, and Potenza Technologies.

The four companies also got help from the UK Office for Zero-Emission Vehicles, with a common goal of creating the first homegrown long-range British EV. And when it comes to electric vehicles, aerodynamics is critical in squeezing out every ounce of driving range from the batteries, and the brainiacs behind Aura EV know this all too well.

But the future of Britain’s EV industry should not only have a more extended range. It needs to be sustainable as well, reducing every ounce of carbon footprints along the way. Aura EV has a lightweight composite body derived from natural fibers. In addition, its svelte yet minimalist silhouette is the result of computational fluid dynamics to make it as slippery as a fish in the water. And if those covered rear wheels are any indication, Aura EV can slice the wind almost effortlessly.

Unfortunately, some details are pretty scarce, but we were lucky to receive more information about Aura EV. According to sources, the car has two 44 kWh battery packs. One of them is on the floor, while there’s also a battery pack under the hood, enough to propel Aura EV to 400 miles (643 km) on a single full charge. If you came here looking for numbers, we’re sorry to disappoint. We’re expecting performance to be peppy for your weekend excursions, but don’t expect it to outrun a Rimac Nevera or Lotus Evija.

One of the central premises behind Aura EV is to reduce people’s perceptions of range anxiety, enabling buyers to adopt the EV lifestyle without further hesitations. Other quirks include a custom steering wheel with a self-positioning screen and a hi-tech human-machine interface with 3D visualization. Meanwhile, Aura EV’s Android-sourced battery and charging software can monitor the state of charge within 0.5-percent for superior accuracy, ensuring drivers will never unexpectedly run out of juice or wait unnecessarily at a charging station.
