SRE role with DevOps for Enterprise [@HPE podcast]

sre-series

My focus on SRE series continues… At RackN, we see a coming infrastructure explosion in both complexity and scale. Unless our industry radically rethinks operational processes, current backlogs will escalate and stability, security and sharing will suffer.

Yes, DevOps and SRE are complementary

In this short 16 minute podcast, HPE’s Stephen Spector and I discuss how DevOps and SRE thinking overlaps and where are the differences.  We also discuss how Enterprises should be evaluating Site Reliability Engineering as a function and where it fits in their organization.

“Why SRE?” Discussion with Eric @Discoposse Wright

ericewrightI was a guest on Eric “@discoposse” Wright of the Green Circle Community #42 Podcast (my previous appearance).

LISTEN NOW: Podcast #42

In this action-packed 30 minute conversation, we discuss the industry forces putting pressure on operations teams.  These pressures require operators to be investing much more heavily on reusable automation.

That leads us towards why Kubernetes is interesting and what went wrong with OpenStack (I actually use the phrase “dumpster fire”).  We ultimately talk about how those lessons embedded in Digital Rebar architecture.

yes, we are papering over Container ops [from @TheNewStack #DockerCon]

thenewstackIn this brief 7 minute interview made at DockerCon 16, Alex Williams and I cover a lot of ground ranging from operations’ challenges in container deployment to the early seeds of the community frustration with Docker 1.12 embedding swarm.

I think there’s a lot of pieces we’re still wishing away that aren’t really gone. (at 4:50)

Rather than repeat TheNewStack summary; I want to highlight the operational and integration gaps that we continue to ignore.

It’s exciting to watch a cluster magically appear during a keynote demo, but those demos necessarily skip pass the very real provisioning, networking and security work needed to build sustained clusters.

These underlay problems are general challenges that we can address in composable, open and automated ways.  That’s the RackN goal with Digital Rebar and we’ll be showcasing how that works with some new Kubernetes automation shortly.

Open Source as Reality TV and Burning Data Centers [gcOnDemand podcast notes]

During the OpenStack summit, Eric Wright (@discoposse) and I talked about a wide range of topics from scoring success of OpenStack early goals to burning down traditional data centers.

Why burn down your data center (and move to public cloud)? Because your ops process are too hard to change. Rob talks about how hybrid provides a path if we can made ops more composable.

Here are my notes from the audio podcast (source):

1:30 Why “zehicle” as a handle? Portmanteau from electrics cars… zero + vehicle

Let’s talk about OpenStack & Cloud…

  • OpenStack History
    • 2:15 Rob’s OpenStack history from Dell and Hyperscale
    • 3:20 Early thoughts of a Cloud API that could be reused
    • 3:40 The practical danger of Vendor lock-in
    • 4:30 How we implemented “no main corporate owner” by choice
  • About the Open in OpenStack
    • 5:20 Rob decomposes what “open” means because there are multiple meanings
    • 6:10 Price of having all open tools for “always open” choice and process
    • 7:10 Observation that OpenStack values having open over delivering product
    • 8:15 Community is great but a trade off. We prioritize it over implementation.
  • Q: 9:10 What if we started later? Would Docker make an impact?
    • Part of challenge for OpenStack was teaching vendors & corporate consumers “how to open source”
  • Q: 10:40 Did we accomplish what we wanted from the first summit?
    • Mixed results – some things we exceeded (like growing community) while some are behind (product adoption & interoperability).
  • 13:30 Interop, Refstack and Defcore Challenges. Rob is disappointed on interop based on implementations.
  • Q: 15:00 Who completes with OpenStack?
    • There are real alternatives. APIs do not matter as much as we thought.
    • 15:50 OpenStack vendor support is powerful
  • Q: 16:20 What makes OpenStack successful?
    • Big tent confuses the ecosystem & push the goal posts out
    • “Big community” is not a good definition of success for the project.
  • 18:10 Reality TV of open source – people like watching train wrecks
  • 18:45 Hybrid is the reality for IT users
  • 20:10 We have a need to define core and focus on composability. Rob has been focused on the link between hybrid and composability.
  • 22:10 Rob’s preference is that OpenStack would be smaller. Big tent is really ecosystem projects and we want that ecosystem to be multi-cloud.

Now, about RackN, bare metal, Crowbar and Digital Rebar….

  • 23:30 (re)Intro
  • 24:30 VC market is not metal friendly even though everything runs on metal!
  • 25:00 Lack of consistency translates into lack of shared ops
  • 25:30 Crowbar was an MVP – the key is to understand what we learned from it
  • 26:00 Digital Rebar started with composability and focus on operations
  • 27:00 What is hybrid now? Not just private to public.
  • 30:00 How do we make infrastructure not matter? Multi-dimensional hybrid.
  • 31:00 Digital Rebar is orchestration for composable infrastructure.
  • Q: 31:40 Do people get it?
    • Yes. Automation is moving to hybrid devops – “ops is ops” and it should not matter if it’s cloud or metal.
  • 32:15 “I don’t want to burn down my data center” – can you bring cloud ops to my private data center?

Hybrid & Container Disruption [Notes from CTP Mike Kavis’ Interview]

Last week, Cloud Technology Partner VP Mike Kavis (aka MadGreek65) and I talked for 30 minutes about current trends in Hybrid Infrastructure and Containers.

Mike Kavis

Three of the top questions that we discussed were:

  1. Why Composability is required for deployment?  [5:45]
  2. Is Configuration Management dead? [10:15]
  3. How can containers be more secure than VMs? [23:30]

Here’s the audio matching the time stamps in my notes:

  • 00:44: What is RackN? – scale data center operations automation
  • 01:45: Digital Rebar is… 3rd generation provisioning to manage data center ops & bring up
  • 02:30: Customers were struggling on Ops more than code or hardware
  • 04:00: Rethinking “open” to include user choice of infrastructure, not just if the code is open source.
  • 05:00: Use platforms where it’s right for users.
  • 05:45: Composability – it’s how do we deal with complexity. Hybrid DevOps
  • 06:40: How do we may Ops more portable
  • 07:00: Five components of Hybrid DevOps
  • 07:27: Rob has “Rick Perry” Moment…
  • 08:30: 80/20 Rule for DevOps where 20% is mixed.
  • 10:15: “Is configuration management dead” > Docker does hurt Configuration Management
  • 11:00: How Service Registry can replace Configuration.
  • 11:40: Reference to John Willis on the importance of sequence.
  • 12:30: Importance of Sequence, Services & Configuration working together
  • 12:50: Digital Rebar intermixes all three
  • 13:30: The race to have orchestration – “it’s always been there”
  • 14:30: Rightscale Report > Enterprises average SIX platforms in use
  • 15:30: Fidelity Gap – Why everyone will hybrid but need to avoid monoliths
  • 16:50: Avoid hybrid trap and keep a level of abstraction
  • 17:41: You have to pay some “abstraction tax” if you want to hybrid BUT you can get some additional benefits: hybrid + ops management.
  • 18:00: Rob gives a shout out to Rightscale
  • 19:20: Rushing to solutions does not create secure and sustained delivery
  • 20:40: If you work in a silo, you loose the ability to collaborate and reuse other works
  • 21:05: Rob is sad about “OpenStack explosion of installers”
  • 21:45: Container benefit from services containers – how they can be MORE SECURE
  • 23:00: Automation required for security
  • 23:30: How containers will be more secure than containers
  • 24:30: Rob bring up “cheese” again…
  • 26:15: If you have more situationalleadership-photos-mike awareness, you can be more secure WITHOUT putting more work for developers.
  • 27:00: Containers can help developers worry about as many aspects of Ops
  • 27:45: Wrap up

What do you think?  I’d love to hear your opinion on these topics!
