🚨Running Aws EKS in production is not just about launching a cluster !

😶It’s about engineering for scale, reliability, and application-specific behavior and that only comes with real production experience.
Creating effective solutions based on AWS EkS requires deep production experience. It’s not enough to "spin up a cluster"- you must design, adapt, and operate for real workloads.

Good cloud services are just a set of tools, to create good architectural solutions for applications and then their excellent performance to work on a global scale, you need cool engineers who have experience with such tools🧑‍💻

Here is a good article confirming my words: https://engineering.probo.in/production-grade-pain-lessons-from-scaling-kubernetes-on-eks-03571838c7a3

Cluster API vs Crossplane ⚔️ Which Kubernetes Deployment Tool Should You Choose? 🤔

Just had an interesting deep-dive conversation about Kubernetes deployment strategies. Here's what I've learned about choosing the right tool for deploying K8s clusters across any platform 💼

Cluster API (CAPI) - Most universal, Kubernetes-native approach
Crossplane + CAPI - Choice for unified management
Terraform + K8s Provider - DevOps favorite
Rancher - User-friendly management platform
Kubeadm - DIY approach for full control

You CAN use just Cluster API alone if your goal is purely cluster lifecycle management. But here's when you should consider adding Crossplane.

Cluster API Only is Enough When:
✅ You just need to create/upgrade/scale clusters
✅ Your infrastructure scope is limited to what CAPI providers handle
✅ You're comfortable with CAPI CRDs and clusterctl
✅ Your team is primarily ops/platform-focused

One of CAPI's biggest strengths is its ability to deploy Kubernetes on bare metal hardware servers through specialized providers. This opens up powerful on-premises and edge computing possibilities.

Some of the cool capi's providers for hardware deployment:
Tinkerbell - Bare metal provisioning engine for physical servers
KubeVirt - Virtual machines on Kubernetes
Proxmox - Virtualization platform with KVM/LXC
vSphere - VMware virtualization platform
Metal3 - Bare metal host management

Add Crossplane When You Need:
🚀 Broader infrastructure management (VPCs, databases, storage, etc.)
🔐 Self-service APIs for application teams
🌍 Multi-cloud governance and policy enforcement
🔄 Unified GitOps workflows for both clusters and cloud services

For most enterprise environments, Crossplane + Cluster API gives you the best of both worlds: Crossplane manages the cloud infrastructure, CAPI manages the Kubernetes clusters on top of it.

If you're already using Crossplane (like I am), consider whether you want managed control planes (EKS/GKE/AKS via Crossplane) or self-managed clusters (via CAPI) based on your operational preferences.

✨ Cluster API Only = You're just managing cluster lifecycles (create/upgrade/scale) - basic stuff
🚀 Crossplane + CAPI = You're building a full infrastructure stack

💊 PS: From the latest trends it will also be a good choice for an independent approach and with controller minimization without crossplane deployment of such clusters with the help of these controllers and tools -
* Where can crossplane replace and improve these controllers - https://github.com/flux-iac/tofu-controller, https://github.com/pulumi/pulumi-kubernetes-operator, https://github.com/kro-run/kro
* Gardener can enhance the Сluster API and provide a cool user experience - https://gardener.cloud/blog/2025/08/08-04-cluster-api-provider-gardener/

What's your experience with these tools?

🚀 Kubernetes at Massive Scale – Lessons for Real Production

This experiment shows that Kubernetes can be pushed all the way to 1,000,000 nodes. While it’s not production-ready, the project gives powerful insights:

✅ Think about network design early (IPv6 becomes a must at scale)

✅ etcd writes and API load are the real bottlenecks — optimize them

✅ Sharding + horizontal scaling of control plane components is the key

✅ Every “small overhead” becomes huge at scale — design clean & simple

Even if your cluster is 100 or 1,000 nodes - these patterns help you build reliable, efficient, and future-proof production systems.

🏗 Scaling GitOps: Argo CD + Kargo for 500+ Microservices

Running GitOps for a few services is easy.
Running GitOps for 500+ microservices across multiple environments is a completely different challenge.

At that scale, the classic "commit → PR → merge → sync" workflow quickly becomes a bottleneck:
- endless PRs
- environment drift
- fragile promotion pipelines
- manual verification steps
To keep delivery fast and reliable, GitOps needs automation, orchestration, and abstraction.

This deep dive into Argo CD and Kargo explains how modern platform teams handle GitOps at scale.
Key Technical Takeaways —
🚦 The Promotion Problem
Standard GitOps struggles with environment promotion (Dev → Staging → Prod).
Kargo introduces promotion pipelines that automate artifact movement between stages while maintaining GitOps integrity.
🧩 Abstraction at Scale
Using ApplicationSets and Generators in Argo CD allows platform teams to manage hundreds of applications from a small set of templates, avoiding massive repo duplication.
🔄 Decoupling Environments
Separating application definitions from environment configuration keeps deployments flexible and prevents the dreaded monolithic GitOps repository.
✅ Automated Verification
Promotion pipelines can run tests, health checks, and validations before advancing deployments—removing manual approvals and reducing production risk.

For teams building platform engineering capabilities or operating high-density Kubernetes environments, this is a solid blueprint for scaling GitOps beyond the basics.

🚀 If you're working in Kubernetes, Platform Engineering, DevOps, or Cloud Infrastructure, understanding controllers is becoming one of the most valuable skills you can have.

The controller pattern is the foundation behind Kubernetes, Crossplane, Argo CD, Karpenter, Operators, and many of the platforms shaping the future of infrastructure automation.

As AI and vibe coding continue to evolve, generating code, manifests, Terraform, Helm charts, and automation workflows is becoming easier than ever. But understanding why systems behave the way they do, how reconciliation works, how desired state converges with actual state, and how large-scale platforms operate remains a fundamentally human skill.

The future belongs to engineers who understand the underlying abstractions, not just the tools built on top of them.

If you want to remain relevant in the age of AI-assisted engineering, learning how controllers work is a great investment.

This course is an excellent introduction to one of the most important concepts in modern cloud-native architecture.

Open source AI SRE projects:

3 AM. Checkout down. 17 services alerting. Dashboards open. Logs dig for 20 mins. Pods restarting, fragmented logs. Metrics mismatch found in dependent service; Kafka consumers shifted offsets. Fix: 5-10 mins with runbook. Investigation: 4x longer.

AI SRE agents target this gap. Not chatbots explaining CrashLoopBackOff. Agents pull logs, query Prometheus, check deploys, verify hypotheses, and drop RCAs in Slack with evidence.

Why now? LLMs excel at tool calling; MCP standardized integrations.

6 Open Source Projects:
1. OpenSRE (Python, Apache 2.0, ~8k ⭐️): Investigation agent, 60+ integrations, synthetic incident benchmark. "SWE-bench for incident response."
2. HolmesGPT (Python, CNCF Sandbox, ~3k ⭐️): Production-ready. Reads Alertmanager/PagerDuty alerts (read-only, RBAC), follows YOUR runbooks.
3. K8sGPT (Go, CNCF Sandbox, ~7.8k ⭐️): Kubernetes-only, single binary. Masks object names before LLM.
4. Kagent (Go, CNCF Sandbox, ~3k ⭐️): Framework. Agents/tools as CRDs. Knowledge lives in Git next to ArgoCD.
5. OpenObserve (Rust, ~19.7k ⭐️): Logs+metrics+traces, Parquet on S3. O2 SRE Agent for RCA. Platform open source; Agent Enterprise.
6. Keep (Python/TS, ~12k ⭐️): Enriches 50 raw alerts into one incident before agent starts. Underrated pipeline part.

Key takeaway: Extensible. Internal tool? Write MCP server, agent picks it up. Not a black box; a framework. Runbooks and senior engineer knowledge become agent inputs.

Pay for GPUs, not tokens 👾 10 open source ways to run your own AI platform 🦀

Tokens became a metered utility. Prices are set by a handful of providers, and one pricing change can flip a product's unit economics overnight. Self-hosting is the obvious hedge, and open engines (vLLM, SGLang) are already fast enough.

The gap is the layer above the engine - what turns a model into a scalable endpoint with routing, caching and GPU scheduling. Two tiers here: a focused inference control plane, or a full platform where serving is one workload among many.

TIER 1 ⚙️ - inference control planes. One job: model in, endpoint out.
1️⃣ KServe (~5.7k ⭐️, CNCF) - the standard. One InferenceService CRD for classic ML + LLMs: scale-to-zero, canary, model caching. Bloomberg and IBM run it; Red Hat OpenShift AI is built on top of it.
2️⃣ AIBrix (~5k ⭐️, vLLM project) - pluggable parts, not a monolith: LLM-aware gateway, distributed KV cache, LoRA management. Born at ByteDance, battle-tested on their inference fleet.
3️⃣ llm-d (~3.8k ⭐️) - disaggregated serving, KV-cache-aware routing on Gateway API. Founded by Red Hat, Google, IBM, CoreWeave and NVIDIA; powers the inference layer of Red Hat AI.
4️⃣ vLLM production-stack (~2.5k ⭐️) - the paved road for cluster-wide vLLM: router, Helm, observability, LMCache under the hood.
5️⃣ KubeAI (~1.2k ⭐️) - easiest start: OpenAI API, scale-from-zero, no Istio/Knative needed. Telescope runs multi-region batch inference on it. Caveat: seeking new maintainers.
6️⃣ Kaito (~1k ⭐️, Microsoft) - Workspace CRD provisions GPU nodes itself, ships model presets, covers fine-tuning. Available as a managed AKS add-on.

TIER 2 🔩 - full platforms: build entire AI services.
7️⃣ Ray + Ray Serve (~43k ⭐️) - an AI compute engine: serving, batch, data and training share one runtime; KubeRay puts it on K8s. ChatGPT was trained on Ray; Uber, Spotify and Pinterest run it too.
8️⃣ Kubeflow (~15.8k ⭐️, CNCF) - the whole lifecycle: pipelines, notebooks, training, tuning, with KServe as the serving layer. Born at Google; Spotify and CERN built ML platforms on it.
9️⃣ OpenLLM (~12.4k ⭐️, BentoML) - one command turns any open LLM into an OpenAI-compatible API. DX-first: fast for app teams, a clean artifact for platform.
🔟 NVIDIA Dynamo (~7.5k ⭐️) - datacenter-scale distributed inference: disaggregated prefill/decode, KV cache manager. Adopted by Perplexity, Cursor, Pinterest and PayPal.

Rule of thumb: need an endpoint - tier 1. Building an ML/AI org - tier 2. Mixing is normal: Kubeflow ships KServe, Ray runs on K8s.

On tier 2, Ray Serve composes RAG and multi-model pipelines, BentoML packs a model + business logic into one deployable. For AI agents this tier is the substrate, not the brain - agents call these endpoints, while orchestration (LangGraph, kagent) stays a separate layer.
