Choose Lightsail if a preset virtual-server bundle has enough compute for your workload and its transfer allowance covers your stream. Choose EC2 if you need more control over instance types, configuration, scaling, or AWS networking. Neither one by itself guarantees a continuous broadcast: you must size the host for encoding or relaying, account for outbound data, and build monitoring and recovery around it.
The key first question is whether the server will encode video or simply relay an already encoded feed. Those workloads can need very different compute. Without your resolution, frame rate, codec, input format, AWS Region, and operating plan, there is no defensible universal instance recommendation or exact monthly total.
How Lightsail and EC2 differ for a 24/7 stream
| Decision point | Lightsail | EC2 |
|---|---|---|
| Pricing model | Preset bundles combine compute, memory, storage, and a transfer allowance for a predictable monthly plan price. | Usage-based pricing for the selected instance, with storage, data transfer, and other resources billed separately. |
| Configuration | Simpler VPS-style plans with predefined resource combinations. | Broader choices for instance configuration, scaling, and networking. |
| Best fit | A workload that fits a bundle and can stay within its transfer allowance. | A workload that needs specific capacity, configuration, or AWS infrastructure patterns. |
| Does the service guarantee a continuous YouTube broadcast? | No. Instance pricing is not an uptime or delivery guarantee. | No. Instance pricing is not an uptime or delivery guarantee. |
AWS characterizes Lightsail as a straightforward VPS with predictable pricing and EC2 as resizable compute for a wider range of workloads. Those are useful distinctions, not proof that a particular plan can encode your video or that a single instance will stay healthy indefinitely. AWS describes Lightsail general-purpose plans as suitable for applications including web servers, databases, and batch processing; that description is not a YouTube-streaming benchmark.
Estimate the workload before choosing an instance
Separate encoding from relaying
If the host encodes source video, CPU demand depends on the source format, output resolution and frame rate, codec, and encoding settings. A relay that forwards already encoded video can have very different compute requirements. A low-cost instance should not be assumed capable of a particular encode without testing the actual workload.

Use YouTube’s ingest settings to estimate bandwidth
YouTube’s live encoder guidance gives recommended video bitrates of 10 Mbps for AV1 or H.265 at 1080p30 and 14 Mbps for H.264 at 1080p30. At 1080p60, it lists 12 Mbps for AV1 or H.265 and 17 Mbps for H.264. YouTube recommends constant bitrate (CBR), a two-second keyframe interval (not exceeding four seconds), and RTMPS ingestion. Check YouTube’s current guidance for supported codecs and settings for your chosen resolution and frame rate: YouTube Live encoder settings.
At a constant 10 Mbps, the video payload alone works out to roughly 108 GB per day; at 14 Mbps, roughly 151 GB per day. These are arithmetic estimates using bitrate × 86,400 seconds ÷ 8 ÷ 1,000, not AWS or YouTube usage statistics. Actual transfer can differ with audio, protocol overhead, reconnects, and bitrate behavior, so include margin rather than treating the estimates as a bill forecast.

Compare the AWS costs that matter
Lightsail bundles and transfer allowances
AWS’s public pricing lists Linux/Unix Lightsail bundles with public IPv4 beginning at $5 USD per month: 0.5 GB memory, 2 vCPUs, 20 GB SSD, and 1 TB of transfer allowance. Other listed bundles are $7 per month (1 GB RAM, 2 vCPUs, 40 GB SSD, 2 TB transfer), $12 per month (2 GB RAM, 2 vCPUs, 60 GB SSD, 3 TB transfer), and $24 per month (4 GB RAM, 2 vCPUs, 80 GB SSD, 4 TB transfer). These are listed plan specifications, not evidence of sufficient streaming performance. AWS bills bundles hourly up to the plan’s monthly maximum. See Lightsail pricing and Lightsail documentation for current details.
Lightsail counts both inbound and outbound instance traffic toward the allowance, but charges only excess outbound transfer. Allowances are aggregated for instances on the same bundle in the same Region and reset monthly. AWS lists half-sized instance allowances in Mumbai, Sydney, Jakarta, Malaysia, Hong Kong, and São Paulo compared with the values shown for other Regions. A stream sent continuously to YouTube is outbound traffic, so a 1 TB allowance can be consumed quickly at sustained streaming bitrates. Check the applicable Region’s allowance and excess-transfer charges in AWS’s pricing details.

EC2’s itemized bill
With EC2, include the selected instance, storage, snapshots if used, and internet data transfer out, along with any monitoring or supporting services in your design. AWS documents per-second billing for many operating systems with a 60-second minimum; SLES has different billing treatment. AWS also describes 100 GB per month of internet data transfer out free across AWS services and Regions, except China and GovCloud. That is an account-level aggregated allowance, not 100 GB for each EC2 instance. Beyond it, tiered pricing applies. Confirm current terms for your account and Region using EC2 On-Demand pricing and the AWS pricing calculator.
Do not compare a Lightsail plan price directly with an EC2 compute price and call one cheaper. The stream’s data volume, Region, storage, instance capacity, and supporting services can change the total. The supplied public prices are listed in USD; AWS pricing and transfer allowances vary by Region.

A practical selection process
- Specify the stream. Record resolution, frame rate, codec, audio settings, and target YouTube ingest protocol. Use YouTube’s recommended settings as a starting point, not as an AWS sizing guide.
- Identify the server’s job. Decide whether it will encode source media or relay a prepared stream. If it encodes, test the actual source and output settings on a candidate instance before relying on it continuously.
- Estimate monthly outbound data. Convert the intended video bitrate into daily and monthly data, then add room for audio, overhead, reconnects, and bitrate variation. Compare the estimate against the exact Lightsail Region allowance or the EC2 account’s applicable transfer terms.
- Choose the management model. Prefer Lightsail when a bundle meets tested compute needs and the bundled transfer economics work. Prefer EC2 when its broader configuration, scaling, or networking options solve a real requirement.
- Build the full cost estimate. Include compute, storage, snapshots, outbound transfer beyond applicable allowances, monitoring, and any backup infrastructure. Recheck the AWS calculator and Region pricing before deployment; no single monthly total can be established without those inputs.
- Test continuity before depending on it. Run the stream through representative source material and monitor video, audio, CPU, memory, network use, and reconnect behavior. YouTube advises testing before going live and recommends previewing and monitoring quality. See YouTube’s encoder guidance and YouTube’s live streaming troubleshooting guidance.
Plan for recovery, not just a low instance price
A single virtual machine is a single failure point. A production design should decide what happens if the streaming process exits, the instance becomes unreachable, the network fails, or YouTube drops the ingest connection. Depending on the broadcast’s importance, use a process supervisor or equivalent restart mechanism, health checks, alerts, and a tested backup path. YouTube suggests testing failover for events that use a backup encoder; the appropriate level of redundancy for a continuous channel depends on its impact and budget.
- Use a protected YouTube stream key, keep it out of public scripts and logs, and rotate it if exposed.
- Monitor the actual output and audio, not only whether the VM responds to a health check.
- Test restarts and reconnections with the same encoder and media workflow you intend to run continuously.
- Budget for backup capacity separately; neither Lightsail’s bundle nor EC2’s instance charge automatically provides failover.
