𝗖𝗧𝗢𝘀 𝗮𝗻𝗱 𝗦𝗶𝘁𝗲 𝗥𝗲𝗹𝗶𝗮𝗯𝗶𝗹𝗶𝘁𝘆 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝘀...𝘆𝗼𝘂 𝗺𝗶𝗴𝗵𝘁 𝘄𝗮𝗻𝘁 𝘁𝗼 𝘀𝗲𝗲 𝘁𝗵𝗶𝘀 🌚 How I configured and tracked target Objectives (SLOs) in my GKE infrastructure, to accurately measure its Reliability, 𝗮𝗻𝗱 𝗵𝗼𝘄 𝗶𝘁 𝗰𝗼𝘂𝗹𝗱 𝗯𝗲𝗻𝗲𝗳𝗶𝘁 𝘆𝗼𝘂𝗿 𝗼𝗿𝗴 𝘀𝗲𝘁𝘂𝗽 :) 👇🏾 Soo, how it all began... I set up the infra on @googlecloud @kubernetesio Engine (GKE), then implemented monitoring and alerting of the infra metrics, logs, and events using @PrometheusIO, @grafana, Loki, and Kubernetes Events Exporter, sending alerts to Slack To ensure the high-priority apps were reliable, I... • Engineered a Regional cluster with worker nodes across various zones to withstand zonal failures • Right sized pod resources requests and limits to prevent too many pods from being scheduled on a single node (which could lead to resource contention during spikes) • Ran the high-priority apps, e.g. the DBs with a higher Priority Class to ensure they get scheduled quickly, and don't easily get evicted • Ran 2 - 3 replicas of the critical apps across various nodes across various zones with a PDB, to ensure even if 1 node goes down, its other replicas would be up and prevent downtime To effectively measure the reliability of the high-priority apps which could affect the customers, e.g. the DB cluster, microservices, etc, I defined Service Level Objectives for their availability and latency using the Sloth tool Prometheus & Istio to get the Service Level Indicators metrics. I also created Grafana alert rules to track the apps SLI error ratios and send alerts to the Slack channel when the error budget burn rates exceed certain thresholds. Honestly, this broadened my horizon on Site Reliability Engineering, I learnt various ways to measure if the apps in the cluster are actually as reliabile as they were configured, learning concepts such as calculating... • The Error Budget of an app from its SLO • An app's Error Rate • The error budget burn rate, etc... --- 𝗛𝗼𝘄 𝘁𝗵𝗶𝘀 𝗰𝗼𝘂𝗹𝗱 𝗯𝗲𝗻𝗲𝗳𝗶𝘁 𝘆𝗼𝘂𝗿 𝗰𝗼𝗺𝗽𝗮𝗻𝘆'𝘀 𝗶𝗻𝗳𝗿𝗮 𝘀𝗲𝘁 𝘂𝗽? • Highlight critical, high-priority apps (e.g. customer facing - Ingress/API Gateways, DB Clusters, microservices, etc..), and schedule them on the cluster in ways which will increase their reliability • Define Service Level Objectives for these apps to properly track and measure their reliability using their SLIs • Define alert rules which would fire and page the team when these critical apps burn through their monthly error budget too fast --- 𝗡𝗘𝗫𝗧 𝗨𝗣?? Implement paging of various teams, on-call rotation, and incident response, when critical apps alerts get triggered using tools like @pagerduty (so far, all alerts have been directly forwarded to Slack :) #CTOs #CEOs #VPEngineering #SiteReliabilityEngineering #Observability #DevOps #PlatformEngineering #CloudEngineering #SoftwareEngineering

𝗧𝗵𝗲 𝗰𝗮𝘀𝗲 𝘀𝘁𝘂𝗱𝘆 𝗶𝘀 𝗼𝘂𝘁𝘁𝘁𝘁 😁!!!! I recently made a tweet on how I simulated a DDoS attack against my Google Cloud Kubernetes (Official) (GKE) infra and achieved an 80% block rate on attacks, and 100% success rate on baseline (You can check the tweet out here 👇🏾...) x.com/POnukwili/status/20548… Nowww...I've created a case study, explaining... • the infrastructure architecture, • the challenges before it, • why it is necessary, • my thought process, • its advantages, • and how the set-up could benefit your company's architecture :) 𝗬𝗼𝘂 𝗰𝗮𝗻 𝗮𝗰𝗰𝗲𝘀𝘀 𝘁𝗵𝗲 𝗰𝗮𝘀𝗲 𝘀𝘁𝘂𝗱𝘆 𝗵𝗲𝗿𝗲 👇🏾 confirmed-aardwolf-b44.notio… --- To give you a preamble of what the case study holds in store, 𝗵𝗲𝗿𝗲'𝗿𝗲 𝘀𝗼𝗺𝗲 𝗼𝗳 𝘁𝗵𝗲 𝘀𝗲𝘁-𝘂𝗽 𝗮𝗱𝘃𝗮𝗻𝘁𝗮𝗴𝗲𝘀 • Block unusual traffic from ever reaching your infrastructure, without affecting your baseline (normal) traffic • Avoid unnecessary cloud costs due to scaled-up resources during DDoS attacks (most of the unusual traffic won’t reach your infra. they get caught by @Cloudflare or @googlecloud Cloud Armour) #CTOs #DevOps #PlatformEngineering #DevSecOps #SecurityEngineering #SoftwareEngineering #Cloudflare #GoogleCloud #CloudEngineering #VPEngineering #CEOs #Startups

𝗗𝗘𝗕𝗨𝗚𝗜𝗡𝗚𝗚𝗚𝗚.... That's what I've been doing over the past few days on Terraformmm 😭 I recently completed the manual setup of my @netbird VPN in my @googlecloud Cloud project • Assigned various users to groups and restricted access to certain resources (least-privileged access) • Enabled @Google sign-in (via Google OIDC on NetBird) - (restricting VPN sign-in to ONLY team members), etc... Nowww...I'm re-implementing EVERYTHING, except this time, 𝘂𝘀𝗶𝗻𝗴 𝗧𝗲𝗿𝗿𝗮𝗳𝗼𝗿𝗺 𝗕𝗮𝘀𝗵 𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗻𝗴 𝘁𝗼 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗲 𝘁𝗵𝗲𝗺...and it got me debugging and researching for HOURS 😭...especially using the NetBird Terraform provider (some chicken and egg situation, David can relate 😭) Nonetheless, I've 𝗯𝗲𝗲𝗻 𝗮𝗯𝗹𝗲 𝘁𝗼 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗲 𝘁𝗵𝗲 𝗗𝗡𝗦 𝗭𝗼𝗻𝗲 𝗮𝗻𝗱 𝗿𝗲𝗰𝗼𝗿𝗱 𝗰𝗿𝗲𝗮𝘁𝗶𝗼𝗻 on @googlecloud Cloud DNS and Cloudflare (routed all requests to my 'pe.onukwilip.xyz' subdomain to Google Cloud DNS Zone) I've also been able to automate some aspects of the Netbird VPN server setup (at least the VPN server can be accessed here 🥲 - netbird.pe.onukwilip.xyz, during testing o...I shut it down afterwards 😄)... Currently, the start-up script fails, and there's still a lot to resolve...but we fail forward, right? RIGHT 😭?? 𝗧𝗛𝗘 𝗚𝗢𝗔𝗟?? Achieve a secure infrastructure following "best practices"... • Fully-automated (just provide ur Cloudflare API token) • Least-privileged access (just the right amount of permissions) • Secure (no manual key management, Service Account impersonation instead) • And lastly, provisioning remote/onsite team members with access to ur company's internal Cloud network, without risking public internet access 😉 I'll keep y'all updated on my progress...drafting a case study to properly explain my thought process here and the results of the entire setup Can't wait to be done with this, so I can resume and finally take my Google Cloud Associate Engineer Certification 😌 𝗣𝗟𝗘𝗔𝗦𝗘, 𝗜'𝗠 𝗦𝗧𝗜𝗟𝗟 𝗟𝗢𝗢𝗞𝗜𝗡𝗚 𝗢𝗨𝗧 𝗙𝗢𝗥 𝗗𝗜𝗦𝗖𝗢𝗨𝗡𝗧 𝗩𝗢𝗨𝗖𝗛𝗘𝗥𝗦 𝗜𝗙 𝗨'𝗥𝗘 𝗔𝗪𝗔𝗥𝗘 𝗢𝗙 𝗔𝗡𝗬 🙏🏾!! #CTO #VPEngineering #DevOps #Startups #PlatformEngineering #SoftwareEngineering #Automation #DevSecOps #Cloud #GoogleCloud
