• The need for automation in the world of Kubernetes and cloud native.
• The spectrum of internal platforms, from simple Docker file management to full Heroku-style interfaces.
• The challenges of debugging and understanding complex systems like Kubernetes.
• The benefits of having multiple tools and services for monitoring and logging, such as Grafana Cloud and Honeycomb.
• Importance of observability in understanding application behavior
• EBPF and Pixie for deep insights into system performance
• Redundancies and failovers to minimize downtime
• Debugging challenges and the need for visibility into complex systems
• Observability and metrics as crucial investments, especially with Kubernetes
• The difficulty of building observability infrastructure without automation tools
• Feeding observability data back into automation for automated rollouts and error detection
• Simplifying Kubernetes setup through public sharing of configuration and components
• Inefficiencies in IT teams lead to wasted resources (20% CPU and memory usage)
• CIOs seek to reduce infrastructure costs by consolidating VMs into one massive cluster
• Kubernetes adoption was initially driven by cost savings, but operators saw benefits in its API and extensibility
• Operators found that large clusters can be difficult to manage and upgrade, leading to the concept of "fleets" (small, homogeneous clusters)
• Running small clusters per availability zone or workload type improves manageability and reduces costs
• Stateful workloads pose challenges for Kubernetes and should be handled with caution, either by externalizing databases or using teams to manage them
• Issues with PostgreSQL replication and networking
• Use of Crunchy data and Zalanda operators
• Comparison of managed vs self-managed PostgreSQL services
• Data backup and restore procedures
• Downtime and availability considerations for single instance PostgreSQL
• Trade-offs between feature complexity and simplicity in system design
• Serving stale content when origin is down
• Managed services for databases vs running own infrastructure
• Pitfalls of running multiple stateful sets in Kubernetes
• Technical debt and complexity associated with scaling database operations
• Importance of launching when necessary, rather than prematurely adopting complex solutions
• Delay Kubernetes adoption as long as possible
• Use existing managed platforms instead of managing Kubernetes installations
• Focus on automation and education when adopting Kubernetes
• Be prepared to spend "innovation points" on learning and implementing Kubernetes
• Kubernetes is more complicated than expected, with many configuration options and best practices.
[0.22 --> 5.62] You are listening to ShipIt, a podcast about operations, infrastructure, and the people
[5.62 --> 7.00] that are Kubernetes-ing.
[8.04 --> 8.56] Kubernetes-ing.
[9.28 --> 10.78] K-T-ing, you know what I mean.
[11.44 --> 16.62] I'm your host, Gerhard Lassil, and in this episode, I'm joined by Tamer Saleh, founder
[16.62 --> 20.40] of Super Orbital and former VP of Engineering at Pivotal.
[20.86 --> 25.28] Many years ago, we both used to work in the same London office on Cloud Foundry, and nowadays
[25.28 --> 26.44] we are into Kubernetes.
[26.44 --> 31.32] We start with table tennis, remote work, and then we spend the rest of the time talking
[31.32 --> 33.98] about the challenges that teams have with Kubernetes.
[34.60 --> 39.26] Tamer and his Super Orbital team are deeply experienced in this topic, and they help teams
[39.26 --> 44.78] at companies like Bloomberg, Shopify, and federal US agencies tackle hard Kubernetes and DevOps
[44.78 --> 47.22] problems through engineering and training.
[47.66 --> 50.40] So why do companies need Kubernetes in the first place?
[50.80 --> 52.80] Which are the right reasons for choosing it?
[53.14 --> 54.60] Is Kubernetes even a platform?
[54.60 --> 59.54] My favorite, I'm doing Kubernetes wrong, but it works better than when I was doing
[59.54 --> 59.98] it right.
[60.24 --> 61.16] So what's up with that?
[61.58 --> 63.22] This last one was a lot of fun.
[63.54 --> 66.76] And, as your request, we left the entire minute of laughter in.
[67.08 --> 70.66] Big thanks to our partners Fastly, LaunchDarkly, and Linode.
[71.02 --> 72.82] Thank you for the great bandwidth Fastly.
[73.26 --> 75.34] You can learn more at Fastly.com.
[75.86 --> 80.10] Ship new features with confidence by getting your feature flags powered by LaunchDarkly.com.
[80.10 --> 83.70] And thank you, Linode, for keeping our Kubernetes fast and simple.
[84.20 --> 88.28] Run your setup as we do via Linode.com forward slash changelog.
[88.28 --> 98.70] This episode is brought to you by Honeycomb.
[99.16 --> 103.76] Honeycomb is built on the belief that there's a more efficient way to understand exactly what
[103.76 --> 105.84] is happening in production right now.
[105.84 --> 109.96] When production is running slow, it's hard to know exactly where problems originate.
[110.26 --> 114.18] Is it your application code, your users, or the underlying systems?
[114.18 --> 119.02] Teams who don't use Honeycomb scroll through endless dashboards guessing at what they mean.
[119.26 --> 123.56] They deal with alert floods, guessing which ones matter, and go from tool to tool to tool,
[123.86 --> 125.72] guessing at how the puzzle pieces all fit together.
[126.04 --> 129.70] It's this context switching and tool sprawl that are slowly killing your teams and your
[129.70 --> 130.16] business.
[130.56 --> 135.06] With Honeycomb, you get a fast, unified, and clear understanding of the one thing driving
[135.06 --> 136.44] your business, production.
[136.88 --> 140.94] Honeycomb quickly shows you the correct source of issues, discover hidden problems, even in
[140.94 --> 145.24] the most complex stacks, understand why your app feels slow to only some users.
[145.66 --> 148.12] With Honeycomb, you guess less and no more.
[148.56 --> 153.04] Join the swarm and try Honeycomb free today at honeycomb.io slash changelog.
[153.04 --> 156.02] Again, honeycomb.io slash changelog.
[156.02 --> 172.60] We are going to ship in three, two, one.
[186.02 --> 190.50] It's been several years since we worked together, 2016, 2017.
[191.44 --> 196.08] And I think it's been too long since you and me played the game of table tennis.
[196.54 --> 197.14] How's your game?
[197.24 --> 201.20] I was so bad at table tennis.
[202.16 --> 203.06] That's not true.
[203.46 --> 204.02] That's not true.
[204.16 --> 205.18] I've seen the improvement.
[206.00 --> 208.26] I've seen those years in which you really improved.
[208.66 --> 211.02] And the last games that we've had were really good.
[211.12 --> 212.06] So I enjoyed them.
[212.20 --> 212.92] It was a lot of fun.
[212.92 --> 217.04] I don't know if you know this, it was never official, but it always kind of seemed like
[217.04 --> 221.86] your seniority at Pivotal would directly correlate with how good you were at table tennis.
[222.84 --> 223.24] Yes.
[224.52 --> 226.90] I knew that, but I never mentioned it to anyone.
[227.04 --> 228.60] I think it was like a little thing.
[228.74 --> 229.00] Yes.
[229.68 --> 233.50] I'm pretty sure most of my engineers let me win just to make me feel better.
[233.86 --> 234.58] I'm sorry.
[235.02 --> 235.80] Not me.
[236.98 --> 238.54] No, we had some great games.
