​Beyond Kubernetes: Istio network service mesh




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.

2024 Genesis GV60 RWD Fixes The EV’s Biggest Problem



The ​​2024 Genesis GV60 Standard RWD trim has a starting MSRP of $52,000. The GV60 Advanced AWD and GV60 Performance AWD models start at $60,550 and $69,550, respectively. Another issue cited in SlashGear’s review of the 2023 Genesis GV60 was the vehicle’s limited availability in North America, a problem that hasn’t quite been solved. The GV60 Standard RWD and GV60 Advanced AWD are currently available at select retailers in 23 states, while the availability of the GV60 Performance AWD hasn’t yet been announced.

Despite limited availability, the ​​2024 Genesis GV60 shouldn’t be overlooked when considering a new EV, especially considering its increased range. Other standard features new to the Genesis GV60 include a Wi-Fi hotspot capability, Highway Driving Assist II, and Advanced Forward Collision Avoidance-Assist. Plus, Genesis added more airbags to the 2024 model, as well as a seat belt pretensioner, load limiter, and rear seat belt reminder.

The luxury EV also retains advanced features Genesis had implemented in previous models, including tech that allows drivers to operate their vehicle using fingerprint and/or facial recognition in lieu of a key. Additionally, it uses a glowing crystal ball as its drive shift, which may be the vehicle’s most unique and innovative feature. Anyone interested in purchasing a 2024 Genesis GV60 can visit a local Genesis retailer or the automaker’s website for more details.

The History Of Presidential Aircraft From Roosevelt To Biden



Just as the 20th century dawned, a new age of mankind was dawning. Near the end of 1903, Wilbur and Orville Wright accomplished a previously insurmountable task that would alter the course of humanity for the next century and beyond. On December 17, 1903, the Wright brothers took flight in their flying machine.

The dream to touch the sky was a dream no longer, and it was only a matter of time until the President of the United States grasped the import of the development. Nearly a decade after the Wright brothers took the first flight in human history, former President Theodore Roosevelt became the first President to ever fly.

At the time, Roosevelt had been out of office for over a year. At a county fair in St. Louis, Missouri in 1910, President Roosevelt was flown over the crowd. Although a rather inconspicuous occasion, this would be the historic first for presidential air travel. The brief trip was made in a Wright Flyer by Archibald Hoxsey, who himself worked for the Wright Brothers. The Wright Flyer is the comparatively primitive airplane the Wright Brothers designed to enable air travel. The first airplane was born of the Wright Brothers’ experimentation with gliders, which ultimately led them to attach a propulsion system.

After President Roosevelt’s flight, presidential aviation didn’t really pick up any momentum for over two decades. Although Theodore Roosevelt was the first president to ever take to the sky, it would be his distant cousin, Franklin Delano Roosevelt, who would be in office for the birth of presidential air travel as we know it today.

Nintendo Announces End Of Online Service For 3DS And Wii U Following eShop Shutdown



Nintendo 3DS and Wii U gamers will still be able to play offline games on their devices. Users will also be able to download update data and any software or DLC already purchased from the Nintendo eShop. However, it’s important to note that you cannot simply go and purchase the games you missed out on before the shutdown, as the online store ceased operations in March of this year.

A few services will remain functional after Nintendo completes its general online shutdown. StreetPass, the application that lets users communicate directly between devices, will remain available since it utilizes a local connection. 

Additionally, the “Pokemon Bank” and “Poke Transporter” applications will retain their online functionalities. “Pokemon Bank,” made free earlier this year, allows users to store up to 3,000 Pokemon in an online bank. “Poke transporter” is a companion application to “Pokemon Bank” that allows users to transfer Pokemon from Gen 5 games and the Virtual Console versions of Gen 1 and 2 to their online inventory. 

Although Nintendo is keeping these applications functional for now, it stated that they “may also end at some point in the future.” Many “Pokemon” fans are urging others to transfer their pocket monsters to the Switch’s “Pokemon Home” before it is too late.
