Chris Hickman and Jon Christensen of Kelsus and Rich Staats from Secret Stache discuss the differences between virtual machines (VMs) and containers. What are the pros? Cons? Similarities? Differences?

Mobycast 01: Virtual Machines vs Containers

In episode 20 of Mobycast, Chris recaps another DockerCon 2018 session, how to create effective container images by Abby Fuller. Welcome to Mobycast, a weekly conversation about containerization, Docker, and modern software deployment.

In episode 71 of Mobycast, Jon and Chris discuss lessons learned while working with remote and international engineering teams. Welcome to Mobycast, a weekly conversation about cloud-native development, AWS, and building distributed systems.

Growth Hacking  for Remote and International Developers - Part 1

In the first two episodes of this series, we learned how to build a VPC with public and private subnets. We did a deep dive on NAT, or network address translation, and then setup a software-only VPN for secure access to the private subnets.

Now, it's time to put everything together and earn our cloud networking black belt.

This week on Mobycast, Jon and Chris conclude their three-part series on how to incorporate private subnets for your cloud network. We finish by explaining step-by-step how to move an existing ECS application onto our new private subnets. Now... go build, ninja!

VPC Ninja - Part 3 - Moving an ECS application to private subnets

Back in episode #94 of Mobycast, we showed how Amazon Elastic Container Service (or ECS) makes it easy to inject sensitive data into your containers.

However, ECS only injects secrets at container startup. It's up to you to ensure that the container is restarted if secrets are updated. But who wants to manually restart containers?

In this episode of Mobycast, Jon and Chris are back to provide an automated solution to this problem. We show you step-by-step how to leverage CloudWatch Events and Lambda to automatically update your container secrets. After listening, you'll be able to "automate all things". Well... at least for updating container secrets :-).

Automate all the things - Updating container secrets using CloudWatch Events + Lambda

Cloud lock-in is always fun to talk about. Conversations abound on Twitter, at conferences, and by the water cooler. This week we replay an early episode from June 13, 2018 to see if our opinions on cloud lock-in have changed in the past two years. Spoiler alert: they haven't.

Replay of Ep. 14 - Stop Worrying About Cloud Lock-in

We present to you a remastered and re-released version of one of our early shows from 2018. It was one of our most popular shows of all time, and in it, Chris Hickman recounts his story of being a Microsoft employee dealing with issues of internet scaling in the late 90s to becoming one of the pioneers of NoSQL. Listen to this series to get to know Chris. These are the formative years of the guy who made Mobycast possible with his incredible depth and breadth of development experience.

Replay of Ep. 39 - The Birth of NoSQL and DynamoDB

Podcasts aren't just for making you less bored in traffic anymore. Mobycast can help you level up your software development career by teaching you the tools and techniques of the cloud native pros. Go ahead and keep listening to "Reply All" or whatever garbage true crime podcast you want. Meanwhile that surprisingly capable new develoepr down the hall will be listening to Mobycast and fast tracking her way to a staff architect role.

Along the way, get to know Chris Hickman and Jon Christensen. Both veterans of the industry that almost agree on all things software, but not quite. Just enough tension to keep things interesting as you learn and grow as a developer.

Welcome to Mobycast! This is the second episode that we’re re-releasing from back when we told Chris’s personal story of starting Viathan, which was a software startup built to create one of the first internet scale databases. You’ll get to see how his work in the early 2000’s/late 90’s was instrumental to what later became the databases that we count on today. Anyway, the reason that you should listen to this is not because it’s a fun story but because we’re asking you to trust us here at Mobycast when we tell you what we think is the best way to do distributed systems and cloud-native development, and what better way to learn to trust us than to listen to how Chris got started in this whole world…

Replay of Ep 40 - The Birth of NoSQSL and DynamoDB - Part 2

Welcome to Mobycast! This is the third episode that we’re re-releasing from back when we told Chris’s personal story of starting Viathan, which was a software startup built to create one of the first internet scale databases. In this episode we start to dive into the technical details of how AWS’s Dynamo DB works. If you’re just joining us at Mobycast, this will be your first taste of getting technical with us as we ease you into our library of curated, important cloud-native development topics.

Replay of Ep 41 - The Birth of NoSQL and Dynamo DB - Part 3

Welcome to Mobycast! This is the fourth episode that we’re re-releasing from back when we told Chris’s personal story of starting Viathan, which was a software startup built to create one of the first internet scale databases. In this episode we finish our deep dive into the technical details of how AWS’s Dynamo DB works. If you’re just joining us at Mobycast, thanks for sticking with us through this five part series. By the end, you’ll be ready to join us on any of our other technical deep dives.

Replay of Ep 42 - The Birth of NoSQL and Dynamo DB - Part 4

This is the fifth and final episode that we’re re-releasing from back when we told Chris’s personal story of starting Viathan, which was a software startup built to create one of the first internet scale databases. In this episode, we compare Viathan’s pre-cloud architecture to that of DynamoDB. They’re less different than you might expect!

If you are building software apps, at some point you will likely need to build an image hosting service (let's be honest, probably more than once!). Image hosting is a core feature of many apps, and it's important to get right.

We all know the best practices for building image hosting in the cloud. Start with Amazon S3 for the uploads. Then serve them up with a CDN like CloudFront. Easy, right? Well, as usual, the devil's in the details.

In this episode of Mobycast, Jon and Chris kick off a two-part series detailing how to build a massively scalable image hosting service. We share hard-won tips and tricks so you can avoid common pitfalls when building your own solution.

Hands On AWS - Massively Scalable Image Hosting Using S3 and CloudFront - Part 1

In episode #109 of Mobycast, we started our discussion on how to build a massively scalable image hosting service.  We talked about the general architecture and then dove deep on how to handle image uploads.

But uploading is only half the solution. We also need to allow downloads of the images. Turns out, downloading is a totally different game.

In this episode of Mobycast, Jon and Chris finish their two-part series on building an image hosting solution. We discuss in detail how to enable downloads of files with the help of CloudFront, a global network of edge locations that makes it easy to achieve massive scale.
