For a small AzuraCast-based internet radio station that also sends audio to YouTube Live, start by comparing VPS plans with at least 2 GB RAM and 20 GB of disk; treat that as a minimum, not a guarantee of smooth operation. AzuraCast’s hobby recommendation is stronger: 4 CPU cores, 4 GB RAM and at least 40 GB of storage. DigitalOcean advertises cheaper entry options, but its cited examples have only 1 GB RAM and therefore fall below AzuraCast’s stated minimum.
If you want a YouTube channel kept live from uploaded recordings rather than a VPS-hosted radio station or a live DJ setup, StreamNeo is a simpler cloud alternative: upload a video, add your YouTube stream key and go live. This guide focuses first on choosing and sizing a VPS for AzuraCast.

Which low-cost VPS should you choose?
Choose by resources and total monthly cost, not by the provider’s smallest advertised price. For AzuraCast, the practical shortlist begins at 2 GB RAM and 20 GB storage, with 4 cores, 4 GB RAM and at least 40 GB storage as the more comfortable hobby target. A 1 GB VPS is below the software’s published minimum, even if its price looks attractive.
AzuraCast names Linode (Akamai), Vultr and DigitalOcean as one-click installer choices. The available figures here are not a like-for-like comparison of suitable plans: only DigitalOcean’s cited entry examples have published prices, and both are below the RAM minimum. Check current plan specifications and regional availability directly before buying.

| Option | What is established | How to interpret it |
|---|---|---|
| AzuraCast minimum | 2 GB RAM and 20 GB disk on 64-bit x86_64/amd64 or ARM64; AzuraCast says this does not guarantee perfect operation. | Use as a floor, not a promise that every station workload will run smoothly. |
| AzuraCast hobby recommendation | 4 CPU cores, 4 GB RAM and at least 40 GB disk. | A more sensible target when budget allows, especially if the music library is growing. |
| DigitalOcean shared CPU starting example | Advertised from $4/month; the cited starting example is 1 GB RAM. | Below AzuraCast’s stated RAM minimum; not a suitable recommendation based on this price example alone. |
| DigitalOcean Premium shared CPU entry example | $7/month for 1 GB RAM, 1 vCPU, 25 GB NVMe storage and 1,000 GB transfer. | Also below the RAM minimum. Compare a larger plan and confirm add-on and overage costs. |
| Linode (Akamai) and Vultr | Named by AzuraCast as one-click installer choices; comparable current suitable-tier prices are not established here. | Check current plans meeting your resource target rather than assuming they are cheaper. |
Provider prices and plans change. DigitalOcean’s billing documentation describes per-second billing with a 60-second or $0.01 minimum and a 672-hour monthly cap for bundled CPU Droplets; confirm how those terms apply to the exact plan you select. Review outbound transfer allowances and charges, backups, IPv4 or other extras, and overage rules in the provider’s current pricing information.
How much VPS capacity does an internet radio station need?
RAM and CPU
AzuraCast’s requirements page sets the minimum at 2 GB RAM and 20 GB disk for supported 64-bit x86_64/amd64 or ARM64 systems, while warning that this is not a guarantee of perfect operation. Its hobby recommendation is 4 CPU cores and 4 GB RAM. RAM matters because the application’s database and PHP processes consume memory; do not choose a 1 GB plan just because it is the cheapest advertised tier.

Station workload changes the result. AzuraCast notes that serving listeners is often less CPU-intensive than transcoding, but actual capacity depends on the workload. A YouTube output that packages a simple audio program with a static image has a lighter encoding job than generating complex or high-resolution video; that distinction is not a benchmark of a particular VPS. Shared-CPU performance can vary, so allow headroom and test your own configuration instead of assuming a guaranteed listener count.
Storage for the software and music library
The disk must hold AzuraCast, its operating environment and the station’s music library. AzuraCast notes that the installation uses disk space and recommends leaving free space for upgrades; library size can become the dominant variable. The 20 GB minimum is therefore not a useful music-library target for every station. Estimate your audio collection’s size, then leave room for software updates and growth.

Smart features including Auto Power On, RTC Wake, and Wake-on-LAN make the K1 an ideal choice for home servers, NAS applications, firewall systems, digital signage, and business environments.
Outbound transfer and sustained operation
Your VPS sends a continuous stream to YouTube, and listener delivery may create additional network traffic depending on the station configuration. Verify the provider’s included outbound transfer, overage terms and sustained network limits against your actual output bitrate and audience. A monthly transfer figure alone does not establish comparative network reliability or regional quality; choose a region suitable for your operation and test the route to YouTube.
What YouTube settings should the VPS send?
YouTube recommends RTMPS for live ingest. For H.264 at 720p and 30 fps, its encoder guide recommends a video bitrate range of 3–8 Mbps. YouTube also calls for constant bitrate (CBR) and a 2-second keyframe interval, which should not exceed 4 seconds. These are YouTube encoder recommendations for that video profile, not a VPS sizing benchmark.

- For 720p30, use YouTube’s recommended video bitrate range of 3–8 Mbps; choose settings appropriate to your actual video and network headroom.
- Test the stream and monitor YouTube’s stream health rather than treating a successful connection as proof of a stable broadcast.
An audio radio feed still needs a video stream for YouTube Live, commonly audio paired with a still image or other visual. The radio service and YouTube encoder are separate parts of the setup: confirm how your chosen encoder packages the station output and whether that adds CPU load to the VPS.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Set up AzuraCast and connect a DJ or YouTube output
Install the radio server
- Select the VPS. Choose a supported 64-bit x86_64/amd64 or ARM64 system with at least 2 GB RAM and 20 GB disk; for the hobby target, look for 4 CPU cores, 4 GB RAM and at least 40 GB disk. Confirm the current provider plan’s bandwidth and full charges.
- Install AzuraCast. Follow the current instructions at AzuraCast’s installation guide. AzuraCast is free to install and use, including commercially; the VPS is the hosting cost.
- Configure the station and library. Add station audio and schedules, monitor disk use, and preserve free space for updates. The library determines how much capacity you need beyond the software’s minimum.
- Test automated playback. Confirm that scheduled or continuous station audio is playing as expected before connecting the YouTube output.
For a live DJ
AzuraCast’s streaming software guide identifies Mixxx and BUTT as free, open-source broadcast clients and recommends Icecast mode for its setup. Use the Icecast connection details AzuraCast provides for the station. If remote DJs cannot connect, check whether a reverse proxy such as Cloudflare is interfering with direct broadcaster-port connections; the web interface route and broadcast ports may need separate treatment.

Relay the station to YouTube
Configure an encoder to take the station’s audio output, pair it with a still image or other visual, and send it to the YouTube Live ingest server using the stream key and encoder settings YouTube specifies. Use the RTMPS, bitrate, CBR and keyframe guidance above, then monitor stream health in YouTube. The particular method for taking AzuraCast output into an encoder depends on your chosen software and deployment; do not assume a radio server alone creates a complete YouTube video stream.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Costs and trade-offs to check before paying
- Hosting: compare plans that meet the RAM and disk target, not just advertised entry pricing. Include backups, network transfer, IP charges, taxes where applicable and overages in the monthly total.
- Billing terms: understand whether the price is hourly or monthly, when billing stops, and how the provider caps a billing month. DigitalOcean’s published Droplet terms specify a 60-second or $0.01 minimum and a 672-hour monthly cap for bundled CPU Droplets; verify the selected plan’s applicability.
- Maintenance: a VPS gives you control, but you are responsible for deployment, configuration, updates, storage management, monitoring and recovery planning.
- Workload growth: more listeners, transcoding or complex video can change resource needs. AzuraCast does not establish a universal listener ceiling for a given entry VPS; test before relying on a configuration for a large audience.
Troubleshooting common VPS radio-to-YouTube problems
- AzuraCast is unstable or fails under load: check RAM and CPU usage first. A 1 GB plan is below AzuraCast’s published minimum; move to a plan that meets at least the floor, then evaluate the 4-core, 4 GB hobby target if resource pressure persists.
- The library will not fit or updates run out of room: inspect disk use and reserve free space for upgrades. Expand storage or move to a plan with more disk rather than treating 20 GB as a guaranteed library allowance.
- YouTube reports a weak or unhealthy stream: verify the selected ingest URL and stream key, confirm RTMPS support, check outbound bandwidth, and validate CBR and keyframe interval. Test at the chosen resolution and bitrate while watching YouTube stream health.
- The stream disconnects during sustained use: inspect VPS resource pressure, network transfer limits and encoder logs, then test the connection again. Do not assume an advertised monthly transfer amount proves stable sustained throughput.
- A DJ cannot connect remotely: verify the broadcaster’s Icecast settings and ports. Check whether a reverse proxy is blocking direct broadcaster connections; AzuraCast distinguishes these connections from ordinary web access.
- Listeners report interruptions while YouTube looks healthy: check the station’s listener-delivery path separately from the YouTube output. Listener serving and YouTube ingest are different traffic paths, and capacity depends on the overall workload.
Or let it run in the cloud
If your actual goal is to keep a YouTube channel live from pre-recorded videos, rather than operate AzuraCast on a VPS, StreamNeo runs the playback in the cloud: upload a recording or build a playlist, add your YouTube stream key once, and go live.
