EC2 Instances for Medium Apps

Which ec2 instance is good for medium scale applications

For a **medium-scale application**, you need a balance of **CPU, memory, network performance, and scalability**. The right **EC2 instance type** depends on your application's specific needs (e.g., web app, database, API server). Here are some recommended instance types:

### **1. General Purpose (Balanced CPU & RAM)**
– **t3.medium / t3.large** (2 vCPUs, 4–8 GB RAM)
– Good for low to moderate workloads, like Laravel/Vue apps, small databases
– Cost-efficient (burstable performance)
– **m6i.large** (2 vCPUs, 8 GB RAM)
– Good for web servers, APIs, moderate workloads
– More stable performance than T3

### **2. Compute Optimized (High CPU Usage)**
– **c6i.large** (2 vCPUs, 4 GB RAM)
– Good for CPU-intensive tasks (API processing, batch jobs, high traffic web apps)

### **3. Memory Optimized (High RAM Needs)**
– **r6g.large** (2 vCPUs, 16 GB RAM)
– Good for caching, in-memory databases, high RAM usage apps

### **4. High Performance (If Traffic Grows)**
– **m6i.xlarge** (4 vCPUs, 16 GB RAM)
– Good for scaling up if traffic increases
– Balanced CPU/RAM for Laravel, Vue.js, and DB-heavy applications

### **Additional Considerations**
– **Database**: Use **RDS (Amazon Aurora/MySQL/PostgreSQL)** instead of running DB on EC2
– **Auto Scaling**: Consider **Auto Scaling Groups (ASG)** for handling traffic spikes
– **Elastic Load Balancer (ELB)**: Helps distribute traffic across instances

For your **Laravel + Vue.js app on Apache**, a **t3.large or m6i.large** should be a good starting point. If you expect **higher traffic**, go for **m6i.xlarge**.
