Big data starts small on a VPS
A single VPS won’t replace a cluster, but it’s perfect for learning Hadoop, Spark, or Kafka and running small pipelines. These tools are memory-hungry, so budget 4GB+ of RAM and several CPU cores.
What to prioritize
- RAM first — JVM-based tools like Spark and Kafka eat it fast
- SSD storage for shuffle and checkpoint I/O
- Full root access to tune JVM heap sizes and ulimits
- Extra swap as a safety net for bursty jobs
A Spark-ready box
sudo apt update
sudo apt install openjdk-17-jdk python3-pip
pip install pyspark
Set --driver-memory and --executor-memory conservatively so a 4GB VPS doesn’t OOM. An unmanaged KVM plan gives you the cheapest way to experiment without cloud-per-hour billing.
