It turns out you can t do it all in the cloud. And thus, we have the rise of edge computing, in which data is collected, processed, and analyzed close to the source of its creation and close to where people and systems need it. The goals of edge computing include improving performance, reducing the costs and time of data transmission, and creating new applications to take advantage of that data. Our guide to edge computing is Alex Marcham. Alex is a technologist, writer and researcher. You can find his work at We level-set with a working definition of edge computing, examine the notion of locality and what it means for edge computing, and discuss latency issues. We explore edge computing use cases such as industrial processes and video surveillance, and dive into the infrastructure that drives this technology.

The Datanauts travel to a galaxy of artificial intelligence and machine learning. The good ship InfoSight is piloted by sponsor HPE Nimble Storage as we explore automating infrastructure on today s episode. Our guest is Ryan Brown, Enterprise Storage Architect and Chief Technologist for Storage in Canada at HPE. We talk about InfoSight, HPE’s cloud-based predictive analytics platform that works with HPE’s Nimble Storage arrays, and soon to work with other products from HPE. InfoSight applies machine learning and AI to help customers better manage storage resources and predict problems before they affect the business. We look at the kind of information that InfoSight gathers, how it collects that information and ships it to the cloud, and how it’s protected. We also delve into the value that InfoSight can provide for resource allocation and operational benefits such as preventing outages, maintaining uptime, and improving performance.

Whether by choice or circumstance, it’s inevitable you’ll find yourself looking for a new job. On today’s Datanauts episode we break down the job hunt process to help you understand what you want, what you have to offer, and how to make the most of your application. Our guest is Doug Lane, a tech/ops professional who’s been working in IT for 25 years. He’s also recently gone through the process of finding and getting a new job.  You can follow him on Twitter at @debuggist. Doug shares his experiences and tips about how he approached the job search. We start by talking about honestly understanding your own strengths and weaknesses, and then thinking about what kind of job it is you really want. We also discuss how to evaluate job descriptions, and how to nail the application process. The post Datanauts 133: Perfecting The Job Hunt appeared first on Packet Pushers.

While performing a routine sensor sweep of the Gargleblaster nebula, the crew of the Datanauts starship noticed that many of the tasks are manual in nature and could, with a little effort, be automated with some scripting. However, every time we moved on from one part of the nebula to another, a different error would crop up with the script s code. Isn t there some way that we can automatically test our code to make sure that more time is spent drinking a frothy ale instead of all this debugging? On today’s episode with talk with Adam Bertram, a Microsoft MVP and author of The Pester Book. He is currently a Senior Systems Automation Engineer working with PowerShell, Desired State Configuration, and various other DevOps tools to coordinate reliable software deployments for a biotech company. You can find his work at We start by defining a unit test for scripts, and how unit testing differs from integration, functional, regression tests, and others. Then we dive into why you’d want to test your scripts (testing isn’t just for developers!), and how to create these tests. We also talk about the notion of test-driven development, and dive into Pester, which is a testing framework for PowerShell.

Today on the Datanauts podcast, we land on planet Mentorship to drive around in our exploratory rovers. Why? Mentoring came up on Twitter a while back. Some of you are for it. You invest in your co-workers and your organization by sharing with others what you know. Some of you are against mentoring, arguing that you don t have the time and aren t getting paid to teach other people. And then the Twitterverse connected us to Don Jones, who wrote a book called, Be The Master. Seems like a great excuse to fire up the microphone on our rovers and explore planet Mentorship in more detail. Besides being an author, Don is an an IT pro and PowerShell expert who has created a variety of PowerShell training materials. We talk about how a master/apprenticeship approach can be more effective than formal education, selfish reasons for being a mentor, how to address imposter syndrome, and how to get support for mentorship at work.

If you work for a Value Added Reseller (VAR) as an engineer, the value being added is YOU. What is VAR life? Projects, customer meetings, deadlines, bills of materials, RFP responses, and trying to turn the promises of sales unicorns into an actual design you can install for the customer. We’ve worked for VARs at one time or another, as has our guest Eric Gullickson, who is now Enterprise Architect at Vortex Optics. We thought we d run down the good, the bad, and the ugly of the VAR life on this episode of the Datanauts podcast. We start the show by distinguishing the different roles a VAR can have. Then we dive into the good, which includes access to new technology, paid certifications, a flexible work schedule, and exposure to a wide variety of businesses and operating environments. For the bad, the Datanauts and Eric discuss the blunt reality that you have to generate profit, and you may find yourself having to navigate the competing interests of manufacturers, sales, distributors, and customers. On the ugly side, we swap stories about greasy salespeople, bad project management, and other nightmares.

Today the Datanauts explore three key concepts to make cloud management and operations more bearable: automation, understanding new services and capabilities, and security. Our guest is Kenneth Hui, Technical Marketing Engineer at Rubrik. Ken blogs at Cloud Architect Musings. While our conversation focuses primarily on AWS, many of the principles discussed will apply to any cloud platform. In part one we parse automation, infrastructure-as-code, and DevOps to understand how these concepts are related, how they differ, and why culture and human behavior matter more than labels. Part two explores the latest offerings in AWS including serverless, container support, and machine learning. Part three tackles cloud security essentials including encryption, not exposing S3 buckets, and best practices.

Today, the Datanauts revisit the world of Kubernetes and container scheduling, but we also loop in Serverless or Functions as a Service (FaaS) along with building an incredibly famous project that has literally no code. Our guest is Kelsey Hightower, a Google employee as well as a Kubernetes advocate and expert. We talk with Kelsey about the latest evolution of Kubernetes, whether the notion of Kubernetes lock-in is a concern, and how it’s being used in production. We also delve into serverless computing or Functions as a Service (FaaS) and discuss the technology’s development and adoption. We also explore Kelsey’s latest project, No Code. Last but not least, we look at how containers and orchestration affects the interaction between Devs and Ops, and how to embrace the new world of application design.
