3d isometric version of Lima!!!

(credits: Lesly Zerna & r/aicuriosity for the prompt idea!)

Try Image Prompt 👇

Present a clear, 45° top-down isometric miniature 3D cartoon scene of [CITY], featuring its most iconic landmarks and architectural elements. Use soft, refined textures with realistic PBR materials and gentle, lifelike lighting and shadows. Integrate the current weather conditions directly into the city environment to create an immersive atmospheric mood. Use a clean, minimalistic composition with a soft, solid-colored background. At the top-center, place the title “[CITY]” in large bold text, a prominent weather icon beneath it, then the date (small text) and temperature (medium text). All text must be centered with consistent spacing, and may subtly overlap the tops of the buildings. Square 1080x1080 dimension.

There is a quiet part of data engineering that we rarely say out loud: The more maintenance a data architecture needs, the more it favors the external firm that built it.

👇

I've seen too many "Vendor Agnostic" architectures that are really just "Job Security" architectures. They really are Rube Goldberg machines.

I wrote my latest piece, "The Art of KISSing in Data Architecture," to push back against this entropy.

It's about the DIY Trap: Why serverless usually beats "managing it yourself" (unless you love waking up at 3 AM).

I break down the principles (and the traps) here:

Young David treated his homework like a quiet way to beat yesterday's version of him. This was four years ago. At the time, I shared this achievement along with this message:

"🛫 Fly high, not so the world can see you, but so you can see the whole world! 🌍"

𝐀𝐧𝐭𝐡𝐨𝐬 𝐰𝐡𝐚𝐭?

Anthos functions as a management platform that extends Google Cloud services to run applications consistently across Google Cloud, AWS, Azure, and on-premises data centers, providing a unified management and operational experience. Anthos is explicitly designed as a strong fit for multicloud environments.

𝐊𝐞𝐲 𝐑𝐞𝐚𝐬𝐨𝐧𝐬 𝐀𝐧𝐭𝐡𝐨𝐬 𝐢𝐬 𝐚 𝐆𝐨𝐨𝐝 𝐅𝐢𝐭 𝐟𝐨𝐫 𝐌𝐮𝐥𝐭𝐢𝐜𝐥𝐨𝐮𝐝

✅ Unified Management Console: Anthos provides a "single pane of glass" in the Google Cloud Console to view, monitor, and manage all your Kubernetes clusters and workloads, regardless of where they are deployed (e.g., AWS, Azure, or on-prem). This significantly reduces operational complexity that typically comes with managing disparate cloud platforms.

✅ Operational Consistency: By standardizing on open-source technologies, primarily Kubernetes (GKE), Istio, and GitOps, Anthos provides a consistent application platform and developer experience across all environments. This means application teams can build and deploy applications once ("build once, run anywhere") without worrying about platform-specific details.

✅ Centralized Security and Policy Enforcement: Security policies and configurations (like role-based access controls and resource quotas) can be automated and enforced uniformly across all clusters using Anthos Config Management. This is crucial for maintaining compliance and a strong security posture in a fragmented multi-cloud landscape.

✅ Avoids Vendor Lock-in: Anthos is built on open standards, which gives organizations the flexibility to choose where to deploy their applications based on business needs (e.g., cost, performance, or data residency requirements) and move workloads between platforms if necessary.

✅ Application Modernization: It helps organizations modernize legacy applications by offering tools like Anthos Migrate, which can automatically transform VM-based workloads into containerized applications that can then run on any supported environment.

✅ Service Mesh for Cross-Cloud Communication: Anthos Service Mesh (based on Istio) helps manage, observe, and secure communication between microservices across different clouds, enabling robust, resilient distributed applications. 

𝐂𝐨𝐧𝐬𝐢𝐝𝐞𝐫𝐚𝐭𝐢𝐨𝐧𝐬

Anthos is designed specifically to address the core challenges of managing multi-cloud environments, making it a very strong and suitable solution for organizations seeking unified operations, security, and flexibility across their cloud landscape. 

Anthos involves a learning curve and significant enterprise investment, so it's typically best suited for large organizations with complex, distributed environments.

We tend to overcomplicate data stacks for the wrong reasons:

❌ Because it looks good on a resume.
❌ Because a consultant sold a "bespoke" 6-month project.
❌ Because we are afraid of "Vendor Lock-in" so we create "Complexity Lock-in" instead.

I just published "KISSing the Data Architecture" to explore why the simplest solution is usually the most robust one.

I dive into a specific architectural showdown: The Rube Goldberg Machine vs. The Modern Semantic Layer. One requires a team of engineers to keep the lights on; the other just runs.

The goal isn't to be clever. The goal is to build systems that don't give you a nervous breakdown.
