Show Notes:

Topic 1 - Welcome to the show. Give us a little bit of your background, and some background on how you got involved with the CNCF Cluster testing.

Topic 2 - There are tons of details about your project in the blog post (see show notes), but let’s talk about some of the core things you were able to demonstrate with this testing (OpenStack, OpenShift, OOB Management, Application Deployments, etc.)

Topic 3 - Creating a POC and architecting a large-scale environment are very different tasks. Let’s discuss some of the major design considerations you needed to work out.

Topic 4 - During the build, where were the major time savers or areas where automation was the only way to accomplish your goals?

Topic 5 - Tell us about the applications that were running on the cluster? How did you decide what to test? How do you monitor the environment once it was up and running?

Topic 5 - What lessons can you pass along to anyone looking to architect or test a larger-scale environment? Any scars and scabs that people can avoid?

The Cloudcast #264 - The Evolution of Digital Ocean Aug 19, 2016

Show notes

Brian talks with Mitch Wainer (@mitchwainer; Co-Founder of DigitalOcean) and Nick Van Wiggeren (@NickVanWig; Storage Engineering Manager at DigitalOcean) about the overall cloud market, being focused on developers, how to think about geographic coverage and how many features that customers actually ask for.

Show Notes:

Topic 1 - Welcome to the show. Give us a little bit of your background, and give us a little bit of the story of DigitalOcean - it’s this success story that not that many people know about.

Topic 2 - “the cloud” is a funny thing in that it can be focus on IT replacement, shadow IT, developers, platforms, etc. - but DigitalOcean has always been focused on developers. What does that really mean?

Topic 3 - A lot of cloud providers are chasing really long lists of “features” or “services”, but the DigitalOcean list is much shorter. Does that tell us more about developers preferring simplicity over features, or does it give us a sense of how ready developers are to use embedded services vs. the DIY mentality?

Topic 4 - Recently you announced a block storage offering. Give us some insight into the service/technology, and background on why it’s being announced now - it would seem like compute + storage was needed on Day 1.

Topic 5 - The Big 3 (AWS, Azure, Google) tend to get the bulk of the media headlines for cloud. Tell us something about your customer base that would surprise us about how developers use DigitalOcean instead of those bigger offerings

Topic 5 - DigitalOcean is a Andreessen Horowitz (a16z) backed company. I know that a number of our listeners read their blogs and listen to their podcasts. What do they bring to DigitalOcean as a VC?

Show Notes:

Topic 1 - Welcome to the show. You’re a little bit Internet-famous due to the Wired Magazine article this year, but give us your background and how you got involved with Dropbox.

Topic 2 - There were obviously business reasons why Dropbox did this, but walk us through your thinking about the challenges of designing “Magic Pocket” (codename of the project).

Topic 3 - What does the application and operations team of a large distributed application (or platform) look like? What are the roles? What are the primary concerns and focus areas?

Topic 4 - What did you get right on Magic Pocket and what surprised you as it went into production? What lessons could other people learn from your experience?

Topic 5 - Are you able to share any “today” measurements about where Dropbox is today vs. 2012? People are obviously interested in big migrations and if it was worth all the time/cost/effort.

Topic 6 - What lessons could people learn from this huge migration effort? What was the thought process between business decisions and technical decisions….and how did the process work over the timeframe?

Show Notes:

Topic 1 - Welcome to the show. For anyone that doesn’t know you, tell us about your current role with Google

Topic 2 - This tweet created quite a storm yesterday, https://twitter.com/kelseyhightower/status/758790198603845632. It felt like it started as an acknowledgement of the breadth of the ecosystem, but then went sort of sideways.

Topic 3 - Break down some of the concepts in play for us - Container Format, Container Runtime, Open Container Initiative (OCI), etc.

Topic 4 - Help explain some of this in laymen’s terms for us - isn’t the Docker code open source? Are we getting close to a point where people will have to fork this if they want to use other schedulers?

Topic 5 - Shifting gears a little bit - Kubernetes for beginners - where to start?

Show Notes:

Topic 1 - Welcome to the show. Tell us a little bit about your background and your areas of focus at Black Duck Software.

Topic 2 - For anyone that’s not familiar with Black Duck, what role does Black Duck play in looking at open source licensing vs. actively helping with security and vulnerabilities?

Topic 3 - One of your areas of focus is containers and container security. Obviously containers is top of mind for lots of people. What’s the reality of container security and what are the areas where people should focus their attention?

Topic 4 - Let’s talk about “pre-container” (developers) security vs. “post-container” security (operations). What are the “gates” applications should be going through, and where are people making mistakes today?

Topic 5 - Can we talk about managing security in the container vs. security in the host?

Topic 6 - We have a number of listeners that are going down a journey with containers, either directly (e.g. Docker) or via PaaS platforms (e.g. Cloud Foundry, OpenShift, etc.). What’s your guidance to them?

Show Notes:

Topic 1 - Welcome to the show. Tell us a little bit about your background (lots of interesting companies and roles) and what you’re focused on at ServiceNow today. [Maybe talk a little about what excites you about Enterprise apps vs. Consumer apps (e.g. Zynga)

Topic 2 - Technologists (mostly IT Ops) tend to be drawn to IaaS services because it looks like their current data center and there are lots of moving parts. SaaS (and to some extent PaaS) gets less attention because SaaS is supposed to hide complexity. What are the basics that many companies miss or don’t understand?

Topic 3 - You recently wrote a blog about Enterprise Cloud and Multi-Instance vs. Multi-Tenancy. Don’t things like VMs or Containers provide enough abstraction on compute resources?

Topic 4 - What are the realities of Security in a Multi-Instance vs. Multi-Tenancy environment, especially as it relates to audit and compliance and potential hacking?

Topic 5 - ServiceNow lives at the intersection of ITIL and DevOps - essentially the transition that many companies are trying to make with their applications and operations. How much of these transitions are the tools/platforms vs. people vs. architectures?

Topic 6 - What is your guidance to IT teams and developers as they start using the cloud more, or integrating new applications into their business?

Show Notes:

Topic 1 - You were recently named Executive Director of the CNCF. You have background with the Linux Foundation and strong entrepreneurial experience. Tell us about yourself.

Topic 2 - CNCF got started with Kubernetes, but “Cloud Native Computing” is a very broad domain. What’s the charter of CNCF and how should we think about it in relation to the many other foundations that exist today (Cloud Foundry, OpenStack, Open Networking, etc.)

Topic 3 - Foundations are tricky because of the balance between technology advances and competitive markets. How do you view your role in helping to structure that balance?

Topic 4 - This past week at DockerCon, Docker announced some changes to their technology which will potentially have an impact on Kubernetes and customer choice. Obviously CNCF can’t influence a specific vendor’s approach to the market, but how does leader of a foundation react when the potential market dynamics change?

Topic 5 - How often do you expect to get out and talk to end-customers and how does their feedback get incorporated into foundation activities?

The Cloudcast #257 - Surviving in a Software-Eating World Jun 22, 2016

Show notes

Brian talks with Matt Colyer (@mcolyer; Product Manager at @github | Founder of Flagr and Easel) about the evolution of “software is eating the world” - how application development is evolving; how companies are changing the organizations and process; how IT organizations are dealing with open source software and how SaaS applications like GitHub have to evolve.

Show Notes:

Topic 1 - Welcome to the show. Let’s talk about your background, not only at Github, but also as a developer and entrepreneur prior to Github.

Topic 2 - We all know the famous “software is eating the world” quote from Marc Andreessen, but this means that more companies must be building their own software. Let talk about what Github sees from that perspective - establishing software development as a core business competency. (“insourcing”)

Topic 3 - It’s been interesting to watch more companies, not just vendors, actively participate in open source communities - not just using the software, but actively contributing to existing projects and starting their own projects.

Topic 4 - The public cloud has awesome services available, but not every company feels like they can use the public cloud, so we’re seeing more “on-premises” offerings from public cloud companies. Can you talk about the benefits and challenges of these offerings?

Topic 5 - What’s a trend that you’re seeing from smaller companies that you don’t think enough larger business follow today, but could be easily adopted to make them better at software development or just more agile as a business?

Show Notes:

Topic 1 - It’s been awhile since you were on last. What are you focus areas these days?

Topic 2 - Related to OSS-centric companies, Aaron and I discuss the “will they make any money” question all the time. BV had an event focused on this recently. What was the event?

Topic 3 - There seemed to be a theme that OSS projects need to be delivered as-a-service. I saw a tweet that said, “Uber theme at #bvoss today: we need an OSS license that prevents AWS to make money off of our OSS code.”

Topic 4 - There were several large end-customers (e.g. - banks) in attendance, talking about their OSS projects. Are they making any significant contributions to these projects, or is this mostly an effort to help them hire developers?
