Give us some of the background on Iron.io and how we’ve gotten from the start to where this serverless movement is going these days. Topic 2 - As the serverless movement has started to gain momentum, we’ve been seeing Iron.io mentioned in more and more partnership announcements with platform companies (Docker, Red Hat OpenShift, Cloud Foundry, etc.). Gives us the basics of the Iron.io technologies - How does it augment these platforms? Topic 3 - There seem to be lots of events-driven platforms / frameworks emerging. What are the core elements that developers and operators should be considering? Topic 4 - Iron.io has been doing this for quite a while. What are some of the application and design patterns that customers use the Iron.io platform to accomplish? Topic 5 - What are some of the business challenges that are solved with these events-driven architectures? How do you have a business-level conversation around “serverless”? Topic 6 - Where are the open source elements of Iron.io and which parts are commercial? Feedback?

Give us some of your background in building cloud environments. Topic 2 - Prior to this microservices journey, you had already gone through building a v1 cloud, that was very IaaS focused. Talk about the goals of that cloud, as well as the feedback you got from the “customers”, which were internal developers. Topic 3 - Eventually you built a v2 cloud. What was the focus of that effort? Topic 4 - [Culture] “Don’t break up the monoliths”. “Have ambassadors”. “Stay in the success zone”. Topic 5 - [Containers] Talk about how you got developers to embrace containers. Topic 5a - [Opinionated Platform] Many people talk about having an opinionated platform, but they focus on the side that runs the applications (e.g. container orchestration). You focused on being opinionated on the developer pipeline. Tell us why that was so important. Topic 6 - [Consistency of Applications] What are some of the basic things you had to think about with microservices as you had to deal with things like network latency, tracing/logging, etc.? Topic 7 - [Kubernetes] You've been involve in the Kubernetes community since the v1 announcement. Where do you see the community today? Feedback?

Technologists viewpoint, customers viewpoints, etc. Topic 2 - Were you surprised at how much VMware acknowledged the large public cloud providers (AWS, Azure, Google, IBM) after downplaying them or FUD’ing them for so many years? Topic 3 - Regardless of the re-naming (Cloud Foundation, Cross-Cloud), VMware is still pushing the SDDC. Lots of vendors now have a complete stack story (Cisco, Oracle, Red Hat, Microsoft, VMware, etc.). Do you see the complete story resonating, or is it still pieces and parts depending on buying areas (Apps vs. Infrastructure)? Topic 4 - What is your take on their “Cloud Native” story, between VMware Integrated Containers and Photon Platform? Topic 5 - Michael Dell said that the Dell strategy (going forward) is very focused on Private Cloud, and also included VMware’s revenues streams / cash flows as part of the math to make that huge merger work. So is that VMware’s future - primarily a company selling into private data centers? Topic 6 - The NSX / Cross-Cloud SaaS-delivered services seem to be one of the core innovation areas. Walk me through your thoughts on that, especially the delivery model. Feedback?

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? Feedback?

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? Feedback?

Our first guest from Germany. Give us a little bit of your background and how you got involved in creating Prometheus. Topic 2 - Let’s talk about the basics of Prometheus. What are the core elements and what problems did you intend for it to solve? [From Prometheus homepage: “Prometheus is an open-source systems monitoring and alerting toolkit originally built at SoundCloud.”] Topic 3 - Prometheus is part of the CNCF, which is also where Kubernetes resides, but it can work with lots of different frameworks. Is there a size of deployment where you’ve found that Prometheus starts to make sense? Topic 4 - Adrian Cockcroft has talked a number of times about the challenges of monitoring these fast moving, fast changing systems. What are the biggest challenges of these types of systems that Prometheus is about to solve today? Topic 5 - We’ve traditionally seen (larger) projects come out of a vendor (e.g. Google), into an open source community. Prometheus came out of SoundCloud, which is more of an end-user. How are the projects different in terms of getting community involvement and adoption? Topic 6 - It’s still early in the project’s life, but have you heard of any Cloud projects that want to offer Prometheus-as-a-Service? Feedback?

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? Feedback?

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? Feedback?

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.).

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? Feedback?
