Amazon SageMaker notebook instances now support Amazon Linux 2, so you can now create a new Amazon SageMaker notebook instance to start developing your machine learning (ML) models with the latest updates. An obvious question is: what do I need to do to migrate my work from an existing notebook instance that runs on Amazon Linux to a new notebook instance with Amazon Linux 2? In this post, we describe an approach to migrate your work from an existing notebook instance to a new notebook instance. The following diagram shows an overview of the components in a SageMaker notebook instance and how the migration takes place. Note that this solution isn't limited to a particular version of an Amazon Linux image in the source and destination instance. Therefore, we denote the notebook instance that has existing work and data as an existing or source instance, and to refer the notebook instance that we migrate existing work and data to as a new or destination instance.

AWS Lambda is a serverless compute service that helps you run code without provisioning or managing hardware. You can run AWS Lambda function to execute a code in response to triggers such as changes in data or system state. For example, you can use Amazon S3 to trigger AWS Lambda to process data immediately after an upload. By combining AWS Lambda with other AWS services, developers can build powerful web applications that automatically scale up and down and run in a highly available configuration. Due to its transitory nature and handiness, Lambda has become a popular and integral part of many solutions or architectures.

This post was co-written with Mamoon Chowdry, Solutions Architect, previously at AWS. Businesses and organizations from many industries often struggle to ensure that their data is accurate. Data often has to match people or things exactly in the real world, such as a customer name, an address, or a company. Matching our data is important to validate it, de-duplicate it, or link records in different systems together. Know Your Customer (KYC) regulations also mean that we must be confident in who or what our data is referring to. We must match millions of records from different data sources.

Who invests a database worth of intelligence into the price of a chocolate bar? Turns out, it could be more than half of all retailers. In 2020, 58% of top retailers said they planned to implement some form of AI pricing technology by the end of 2021, according to research conducted for Revionics, a pricing technology company. That compares with 34% in 2020. It's likely they are implementing the technology as pandemic-related inventory delays cause customer-infuriating price hikes: 90% of shoppers said in a recent survey that they plan to switch brands, seek lower prices or cut back on discretionary spending because of higher prices.

Amazon, the owner of Whole Foods, is finally bringing the sort of high-tech features we were expecting to the nationwide grocery chain. Its cashierless Just Walk Out tech will soon arrive in two Whole Foods locations, after starting off in Amazon's own Go grocery stores. Just Walk Out uses computer vision, sensors and AI to let you walk into a store, sign in with an app, fill up your bags and leave without joining a checkout line or scanning your items. I've tested out the systems at my local Amazon Fresh, and I'll begrudgingly admit, it's magical. It's not my go-to grocery store, so I usually only pick up an item or two.

After launching it in Go stores and then bringing it to larger Fresh supermarkets, Amazon's cashierless "Just Walk Out" tech will soon arrive in two Whole Foods locations. The service, which lets you pick up goods from shelves and (yep) just walk out, is coming to new stores in Washington DC and Sherman Oaks, California next year, the company announced. "By collaborating with Amazon to introduce Just Walk Out shopping at these two Whole Foods Market stores, our customers will be able to... save time by skipping the checkout line," said Whole Foods co-founder John Mackey. As we've detailed previously, Just Walk Out uses computer vision, sensors and AI to let you walk into a store, sign in with an app, fill up your bags and leave without the need to join a checkout line. On top of using the tech in its own Go and Fresh stores, Amazon signed a deal last year to license its technology to third-party retailers.

The lessons of this book are delivered in clear language and without technical jargon. I've worked with Randy Bean for almost twenty years, and I've read a lot of his writing. He prides himself on his ability to communicate about technical subjects to people with no technical backgrounds. If you are someone in a business role who has heard about such topics as big data, artificial intelligence, and digitization, and you want to know what all the fuss is about without getting lost in technical detail, you have come to the right place.

As online shopping becomes increasingly the norm, there will be plenty of job openings for Amazon warehouse workers. That is, until Amazon reaches its ultimate goal of replacing all human warehouse employees with sticky, eight-legged robots (or Jeff Bezos clones). Naturally, Amazon's robots will produce enormous quantities of gunk. That's why the No. 1 job in the near future will be a gunk scrubber. That is, until Amazon invents a gunk-scrubbing robot, at which point the only job left in the warehouse will be a semi-licensed robo-spider-maintenance technician.
