Download Driver Uber App NEW!

If you're going to use Uber in and around Cincinnati, take a good look at the driver. It might just be Xavier's 6-foot-10, admittedly quirky second-leading scorer, Matt Stainbrook. We decided to go along for the ride. (3:02)

Kind of like the driver himself. The fifth-year senior center is ... "quirky is the right word -- very, very quirky," says his coach at Xavier, Chris Mack. "Weird. You know, I think Matt's originally maybe from Portland, Oregon, where they always talk about the theme being 'Keep Portland Weird.'"

Stainbrook's daily downshift, from mastering the pick-and-roll as the Musketeers' second-leading scorer, to rolling down the highways and through the side streets of Cincinnati as an Uber driver, wasn't made to up his quirky quotient.

The way it works is simple. Matt has an app on his phone, and when he activates it, he's available to pick up passengers. When a call comes in, Uber pings the nearest driver. If that's Matt, he and his sweet-riding, gold Rendezvous are off.

The flexibility is perfect. There are no set hours; he essentially turns on the app whenever he wants to work. If a call comes in and he's not interested, he ignores it. In 15 seconds, Uber will contact the next-nearest driver. Everything is done electronically -- passengers link a credit card -- so there's no need for him to bring cash, and he's paid weekly via direct deposit.

Since he started in September, Matt has chauffeured students in the wee hours leaving bars, and older couples heading out to a quiet dinner. Some know who he is -- "The best comment I ever got was, 'Good driver, better hook shot'" -- and some do and pretend they don't, surreptitiously trying to take pictures from the backseat; some have no idea; and some ask because he's 6-foot-10 and 270 pounds.

Pod

In the kitchen, a pod would be the plate/tray that holds your soup and salad. In Kubernetes, a pod is something that can hold 1 or more containers. The reason for this is that containers within a pod can communicate with each other.

Let's stop here for a second. If you understand everything I've said up to this point, you understand the basics of Kubernetes architecture! If you don't want to rely on the kitchen imagery forever, I've replaced all the kitchen drawings with only Kubernetes terminology in the diagram below.

Me: Yep, the last part of the puzzle is understanding how Kubernetes is used. How do humans interact with Kubernetes? How is Kubernetes relevant/useful in the world of technology? Let's lean back on our kitchen analogy for a second to explain some more concepts.

The customers eating at the restaurant is analogous to the users of an app or service. Similar to how the Mcdonalds kitchen produces Big Macs for me to eat, the Spotify Kubernetes cluster is providing me the service of listening to a large selection of music from a web browser.

And of course, I realize there are some abstractions I left out of my explanation because I felt like they were not important in forming a basic mental model of Kubernetes. Feel free to dig in more. As I dig in more myself, I may add to this blog with some links to resources I find useful.

The reason why I picked this mode of storytelling (describing tech through the lens of a conversation with an Uber driver) is because I wanted to break down Kubernetes into something that was universally understandable and felt approachable.

Thanks for writing this beautiful article. I had been reading about and working with some practical kubernetes for a while now and this article just humbles me to my core about how simplified yet complete one can write. Great Read

The idea here would be Kubernetes handles the gritty details of container orchestration, and provides a higher-level abstraction for you to orchestrate your containers. Put another way, you tell Kubernetes what actions to carry out and it does so, handling the complex details of how.

Thank you for this beautiful and insightful article. I am a beginner right now, learning about Kubernetes and Docker. This article gave me a good idea of how Kubernetes works. The analogy was on point...!!??

Uber Technologies, Inc., commonly referred to as Uber, provides ride-hailing services, food delivery, and freight transport.[2] The company is headquartered in San Francisco and operates in approximately 70 countries and 10,500 cities worldwide.[2] The company has over 131 million monthly active users and 6 million active drivers and couriers worldwide and facilitates an average of 25 million trips per day. It has facilitated 42 billion trips since its inception in 2010 and is the largest ridesharing company in the United States.[3].mw-parser-output .toclimit-2 .toclevel-1 ul,.mw-parser-output .toclimit-3 .toclevel-2 ul,.mw-parser-output .toclimit-4 .toclevel-3 ul,.mw-parser-output .toclimit-5 .toclevel-4 ul,.mw-parser-output .toclimit-6 .toclevel-5 ul,.mw-parser-output .toclimit-7 .toclevel-6 ul{display:none}

In 2009, Garrett Camp, a co-founder of StumbleUpon, came up with the idea to create Uber to make it easier and cheaper to procure direct transportation. Camp and Travis Kalanick had spent $800 hiring a private driver on New Year's Eve, which they deemed excessive, and Camp was also inspired by his difficulty in finding a taxi on a snowy night in Paris.[4][5] The prototype of the mobile app was built by Camp and his friends, Oscar Salazar and Conrad Whelan, with Kalanick as the "mega advisor" to the company.[5]

The company's early hires included a nuclear physicist, a computational neuroscientist, and a machinery expert who worked on predicting arrival times for Uber's cars more accurately than Google APIs.[4][11] In April 2012, Uber launched a service in Chicago, whereby users were able to request a regular taxi or an Uber driver via its mobile app.[12][13]

In July 2012, the company introduced UberX, a cheaper option that allowed drivers to use non-luxury vehicles, including their personal vehicles, subject to a background check, insurance, registration, and vehicle standards.[14][15] By December 2013, the service was operating in 65 cities.[16]

Like other ridesharing companies, the company classifies its drivers as gig workers/independent contractors. This figure has become the subject of legal action in several jurisdictions. The company has disrupted taxicab businesses and allegedly caused an increase in traffic congestion. Ridesharing companies are regulated in many jurisdictions and the Uber platform is not available in several countries where the company is not able or willing to comply with local regulations. Controversies involving Uber include various unethical practices such as aggressive lobbying and ignoring and evading local regulations. Many of these were revealed by a leak of documents showing controversial activity between 2013 and 2017 under the leadership of Travis Kalanick.

Uber has been criticized for its strategy of generally commencing operations in a city without regard for local regulations. If faced with regulatory opposition, Uber called for public support for its service and mounted a political campaign, supported by lobbying, to change regulations.[78] Uber argued that it is "a technology company" and not a taxi company, and therefore it was not subject to regulations affecting taxi companies.[78] Uber's strategy was generally to "seek forgiveness rather than permission".[79] In 2014, with regards to airport pickups without a permit in California, drivers were actually told to ignore local regulations and that the company would pay for any citations.[80] Uber's response to California Assembly Bill 5 (2019), whereby it announced that it would not comply with the law, then engaged lobbyists and mounted an expensive public opinion campaign to overturn it via a ballot, was cited as an example of this policy.[78][81]

More than 124,000 Uber documents covering the five-year period from 2012 to 2017 when Uber was run by its co-founder Travis Kalanick were leaked by Mark MacGann, a lobbyist who "led Uber's efforts to win over governments across Europe, the Middle East and Africa",[82] to The Guardian newspaper and first printed on 10 July 2022 by its Sunday sister The Observer. The documents revealed attempts to lobby Joe Biden, Olaf Scholz and George Osborne; how Emmanuel Macron secretly aided Uber lobbying in France, and use of a kill switch during police raids to conceal data. Travis Kalanick dismissed concerns from other executives that sending Uber drivers to a protest in France put them at risk of violence from angry opponents in the taxi industry, saying "I think it's worth it, violence guarantees success".[83]

On February 27, 2015, Uber admitted that it had suffered a data breach more than nine months prior. Names and license plate information from approximately 50,000 drivers were inadvertently disclosed.[124] Uber discovered this leak in September 2014, but waited more than five months to notify the affected individuals.[125]

An announcement in November 2017 revealed that in 2016, a separate data breach had disclosed the personal information of 600,000 drivers and 57 million customers. This data included names, email addresses, phone numbers, and drivers' license information. Hackers used employees' usernames and passwords that had been compromised in previous breaches (a "credential stuffing" method) to gain access to a private GitHub repository used by Uber's developers. The hackers located credentials for the company's Amazon Web Services datastore in the repository files, and were able to obtain access to the account records of users and drivers, as well as other data contained in over 100 Amazon S3 buckets. Uber paid a $100,000 ransom to the hackers on the promise they would delete the stolen data.[126][127] Uber was subsequently criticized for concealing this data breach.[128] Dara Khosrowshahi publicly apologized.[129][130] In September 2018, in the largest multi-state settlement of a data breach, Uber paid $148 million to the Federal Trade Commission, and admitted that internal access to consumers' personal information was closely monitored on an ongoing basis was false, and stated that it had failed to live up to its promise to provide reasonable security for consumer data.[131] In November 2018, Uber's British divisions were fined 385,000 (reduced to 308,000) by the Information Commissioner's Office.[132] ff782bc1db
