| What Is A Microservices Architecture?
Simple Definition:
Microservices architecture is like running a restaurant kitchen where each chef specialises in just one task:
One chef only grills burgers 🍔
Another only fries chips 🍟
Another only makes milkshakes 🥤
Each chef undertakes a specific role, yet they collaborate to provide your complete meal.
In Software Terms:
Instead of building one big program that does everything (a “monolith”), you build small, independent services.
Each microservice handles just one part of your app (e.g., payments, user login, orders, reviews).
These services talk to each other through APIs (like passing food across the kitchen counter).
Why it’s great: If the milkshake machine breaks, burgers and chips can still be made! No need to shut the whole kitchen down.
| What Are Containers in This Analogy?
Imagine each chef (microservice) operating from their own mobile kitchen cart, equipped with their own tools, ingredients, and recipes — nothing is shared unless it’s deliberate.
These self-contained units are like containers in software.
Containers package everything needed to run a service — the code, settings, tools — so it works anywhere.
Why containers? If you move the burger chef to another branch, he still has everything he needs to cook the same burger, no surprises.
| Why Do You Need a Container Orchestration Platform?
Now, imagine you’re managing a food court with 100+ chefs, each with their own mini kitchen cart (containers). It gets chaotic fast. Who’s working? Who’s idle? Where do new chefs go?
You need a manager to coordinate all this.
That’s where container orchestration comes in — it’s like a head chef or kitchen manager who:
Starts and stops containers (chefs) as needed
Makes sure there are always enough chefs for rush hour
Moves chefs between stations if one goes down
Keeps records of what each chef is doing đź“‹
| AWS EKS vs. AWS ECS in Simple Terms
| ECS: The Simple Restaurant Manager 🍽️
AWS ECS is like hiring Amazon’s in-house kitchen manager.
It’s easy to use, knows the layout, and speaks the local language (AWS).
You say, “Give me five burger chefs during lunch rush” → ECS handles it.
Best for: Teams who want to focus more on cooking (coding) and less on managing staff (infra).
| EKS: The Michelin-Star Global Manager 👨🍳
AWS EKS is like hiring a famous restaurant consultant (Kubernetes) to design your kitchens.
They need more setup, but they’re super smart and flexible.
They can manage staff in multiple branches, even in other cloud platforms.
Best for: Larger or more technical teams who want fine-grained control and cloud portability.
