AWS EC2 vs Lightsail: Which to Choose for a Small Project
Practice4 minInnovialabs editorial team
In short
Lightsail is a simple AWS VPS with a fixed price for a bundle of resources and traffic, a good fit for websites and small apps; EC2 offers flexibility, auto scaling and full AWS networking but needs setup and attention to billing. You can start on Lightsail and export the server to EC2 later.
Short answer: what is the difference
Amazon Lightsail is simplified hosting inside AWS. You pick a plan, and the fixed monthly price already includes CPU, memory, SSD storage, a public IP and a data transfer allowance. The interface feels like a regular VPS provider.
Amazon EC2 is the core AWS compute service. You assemble a server from separate parts: instance type, EBS volume, VPC network, IP address, traffic. Each part is billed separately based on usage.
If the project just needs a reliable server, Lightsail is simpler and more predictable. If you need auto scaling, special machine types or complex networking, choose EC2.
Key differences side by side
| Aspect | Lightsail | EC2 |
|---|---|---|
| Pricing model | Fixed monthly plan | Pay-as-you-go per resource |
| Bill predictability | High | Depends on load and traffic |
| Outbound traffic | Allowance included, overage extra | Billed separately |
| Configuration choice | Limited set of plans | Hundreds of types, including GPU and ARM |
| Networking | Simple firewall, its own isolated network | Full VPC, subnets, security groups |
| Scaling | Manual, via snapshot and a bigger plan | Auto Scaling, load balancers, Spot instances |
| Commitment discounts | None | Savings Plans, Reserved Instances |
| Learning curve | Low | Requires understanding AWS |
Price predictability and traffic
With Lightsail you know the bill in advance: the plan covers the core resources, and extra charges come mainly from exceeding the traffic allowance, additional disks and snapshots.
With EC2 the bill has many lines: instance hours, disk size and type, public IPv4 addresses, outbound traffic, snapshots. For a small project the total can be comparable, but surprises most often hide in traffic and forgotten resources.
Networking and managed add-ons
Lightsail offers its own simplified add-ons:
- managed MySQL and PostgreSQL databases;
- load balancers with SSL certificates;
- CDN distributions, object storage and a container service;
- static IPs and DNS zones.
Lightsail can reach other AWS services through VPC peering, but network flexibility is limited.
EC2 runs inside a full VPC: private subnets, NAT, VPN, fine-grained access rules and IAM roles for instances. The whole AWS catalog is next door: RDS, ElastiCache, SQS, ECS and more.
Scaling
- Lightsail: to grow a server, you take a snapshot and create an instance from it on a larger plan. For multiple servers you add a load balancer, but there is no automatic scaling with load.
- EC2: you can change the instance type after stopping it, and for variable load set up an Auto Scaling group that adds and removes servers on its own.
When Lightsail fits
- A company website, landing page, blog or WordPress.
- An MVP or small web app with predictable load.
- Test and staging environments.
- A team without a dedicated DevOps engineer.
- You want the same bill every month.
When EC2 fits
- Load changes noticeably during the day or by season.
- You need GPUs, large memory or specific instance types.
- You require private networking, a VPN to the office or strict security rules.
- The architecture combines many AWS services.
- You have the skills to monitor costs and manage infrastructure.
How to migrate from Lightsail to EC2
Lightsail has a built-in export to Amazon EC2 feature:
- Create a snapshot of the Lightsail instance.
- In the Lightsail console, export the snapshot to EC2; it becomes an AMI and an EBS snapshot.
- Launch an EC2 instance of the right type from that image and choose the VPC and security group.
- Move traffic by updating DNS records to the new address.
- If the database lived in a Lightsail managed database, move it to RDS with a dump.
- Verify everything works, then delete the old resources so you do not pay twice.
To keep migration easy, store configuration in code or scripts from the start and do not tie the application to files that exist only on the server.
