4 CPU VPS Hosting

A 4 CPU VPS at Anubiz Host typically gives you 4 dedicated EPYC Genoa or Xeon Scalable threads pinned at the hypervisor scheduler, 8 to 16 GB of DDR4 or DDR5 ECC memory, 80 to 200 GB of NVMe storage in RAID 10 and full IPv4 plus a /64 IPv6 block on a 1 Gbit uplink. The NVMe array delivers tens of thousands of mixed IOPS, which is enough for Postgres workloads under sustained writes and for Elasticsearch or OpenSearch indexes up to several million documents. KVM gives you snapshots, custom kernels and full ISO upload.

Customers run a mid sized SaaS with hundreds of paying users on a 4 CPU VPS, a multi tenant mail server with full anti spam stack, a single node K3s Kubernetes cluster with around 20 to 30 pods, a private Docker registry feeding a small fleet of build agents, a Matrix Synapse server federated with a few thousand other servers, a Mastodon instance for a community of a few hundred active users and ad tech components such as small RTB bidders and click tracking endpoints. The four core allocation gives enough parallelism for both serving and background workers.

Right sizing on the 4 CPU tier means watching CPU steal, run queue length and IO wait together rather than just headline CPU percentage. If you see steal under 1 percent and run queue rarely above the core count, you have headroom. If steady state CPU sits around 60 percent with bursts to 90, you are healthy. Move to 8 cores when peaks routinely hit 100 percent and queue depth grows, or when you add a second memory hungry component such as a search index or a vector store. Anubiz Host upgrades are in place and crypto settled.
