Host it in Brazil with restart monitoring and structured logs. ## When to choose Java[](https://streethosting.com.br/en/guides/discord-bots/host-java-discord-bot#quando-java) Teams that already maintain Java Minecraft plugins, JDBC integrations or corporate language policies tend to standardize their bots on the JVM. For a simple moderation bot, Node is still quicker to work with. ## JVM and RAM[](https://streethosting.com.br/en/guides/discord-bots/host-java-discord-bot#jvm-e-ram) | Parameter | Starting suggestion | Reason | | --------- | ------------------- | ----------------------------------------- | | Xmx | 512M to 1G | Avoids OOM in medium-sized guilds | | Xms | Same as Xmx | Reduces resizing at runtime | | Threads | Limited pool | Prevents a thread explosion with sharding | ### Rate limit Handle 429 responses as described in [fixing the Discord rate limit](https://streethosting.com.br/en/guides/discord-bots/fix-discord-429-rate-limit). ## Production deployment[](https://streethosting.com.br/en/guides/discord-bots/host-java-discord-bot#deploy) * Token in an environment variable * Versioned jar with a hash at deploy time * HTTP healthcheck if you expose metrics * Alert if restarts > 3 per hour * systemd with Restart=on-failure * JSON logs for later searching * Config backup kept off the server ## Hosting in Brazil[](https://streethosting.com.br/en/guides/discord-bots/host-java-discord-bot#host-brasil) Run managed bots on the [bot plans](https://streethosting.com.br/en/bots) when your team is small.

The JVM baseline is higher. For simple bots, Node is usually lighter. Java pays off in enterprise integrations, strong typing and a mature queue ecosystem. Which GC should I use? G1 or ZGC on recent versions, with the heap set explicitly. Never let the JVM grow until the host runs out of memory. Xeon or Ryzen for a Java bot? An I/O-bound bot that talks to a database and APIs: a stable Xeon. A bot with heavy synchronous processing per command: consider Ryzen.
