Hey there! When you build an app, one of the most important decisions is choosing the right infrastructure. If you pick the wrong one, you might face problems with cost, maintenance, or performance later.
In this post, we will compare three popular options: AWS Lambda, containers (ECS/EKS), and servers (EC2). Let's dive in! 💡
AWS Lambda: Serverless Simplicity ⚡
Lambda is a serverless option, meaning you don’t have to manage servers. Just write your function, deploy it, and AWS takes care of everything. It automatically scales based on the workload.
✅ Pros:
-
Cost-effective 💰 – You only pay for execution time, no idle costs.
-
Fast to deploy ⚡ – Just write the code and push it live.
-
No maintenance 🛠️ – No need to update servers, just your app dependencies.
-
Auto-scaling 📈 – No need to configure load balancers.
❌ Cons:
-
Execution time limit ⏳ – Max 15 minutes per function.
-
Cold starts 🥶 – The first execution after scaling up can be slow.
-
Best for: Event-driven apps, cron jobs, unpredictable workloads.
AWS ECS/EKS (Containers): Flexibility & Portability 🐳
Containers allow you to package your app and run it anywhere. AWS offers multiple ways to run containers, such as ECS, EKS (Kubernetes), and Beanstalk.
✅ Pros:
-
Portability 🚀 – Move your app between different cloud providers.
-
Faster deployments ⏩ – Compared to traditional app-managed services.
-
Better performance 🔥 – Suitable for both low and high CPU-intensive apps.
-
More configuration options 🛠️ – Choose exactly how your app runs.
❌ Cons:
-
Requires a load balancer ⚖️ – Extra cost if scaling automatically.
-
More expensive than Lambda 💵 – If the app runs infrequently.
-
Best for: APIs, WebSockets, and apps needing low latency or more control.
Servers (EC2, VPS) 🖥️
Full control, more work. The traditional approach: rent a server, install your OS, and manage everything yourself. AWS EC2 and Lightsail offer this option.
✅ Pros:
-
Best cost-performance ratio 💸 – If you optimize it well.
-
Full control 🔧 – You configure everything.
-
Custom OS/hardware support 🖥️ – If your app requires special configurations.
❌ Cons:
-
Complex to manage 😓 – You install and update everything manually.
-
Hard to scale 📉 – Load balancing and scaling require more work.
-
Security responsibility 🛡️ – You must handle updates and security.
-
Best for: CPU-intensive apps, AI/ML workloads, and custom configurations.

Final Thoughts
If you want the simplest and most cost-effective option, Lambda is a great choice.
If you need flexibility and fast deployments, go with containers.
If you require full control and high performance, servers might be the best.
