AWS EC2 vs Lightsail — Which One Saves You More Money?

Pricing Model EC2: Pay-as-you-go (billed per second/hour based on instance type and usage). Lightsail: Fixed monthly pricing with bundled resources (compute, storage, data transfer). Resource Bundling EC2: Compute and storage (EBS) billed separately. Lightsail: Bundled packages include SSD storage, RAM, and data transfer. Example Monthly Cost EC2 (t3.micro): ~$8.60/month (excluding EBS, data transfer, etc.). Lightsail (512MB RAM, 1 vCPU, 20GB SSD): $3.50/month (all-inclusive). Data Transfer EC2: First 1GB/month free, then charged per GB. Lightsail: Free data transfer allowance (e.g., 1TB/month), extra charged at flat rates. Pricing Predictability EC2: Cost varies depending on instance hours, EBS, IPs, etc. Lightsail: Fixed cost makes budgeting simpler. Instance Flexibility EC2: Broad range of instance types (general purpose, compute, GPU, etc.). Lightsail: Limited instance types, suitable for simple workloads. Scalability EC2: Highly scalable with auto scaling groups, Elastic Load Balancers, etc. Lightsail: Basic vertical scaling; lacks advanced scalability features. Additional Services EC2: Deep integration with AWS services like VPC, EBS, CloudWatch, IAM, etc. Lightsail: Limited integrations; offers its own managed services (databases, containers). When to Use EC2? Choose EC2 when: You need custom networking and full control (e.g., VPC, subnets, security groups). You are running enterprise-grade or production-level apps. You require advanced autoscaling, load balancing, or specialized hardware (like GPUs). You want to host containers (ECS/EKS) or build a highly available architecture. When to Use Lightsail? Choose Lightsail when: You’re hosting blogs, websites, or small web apps. You want a simple, budget-friendly setup with predictable pricing. You’re a beginner or developer testing small projects. You want to quickly launch apps like WordPress, LAMP, or Node.js using pre-configured blueprints. Venkat C S
