Pick a VPS for the workload you will run, not for the biggest number on the plan card.
ArkHost lists CPU cores, allocated RAM, NVMe storage and traffic for every Linux VPS plan. Those are the numbers that matter. Start with the application, then work through each resource.
CPU cores
CPU matters when the server is actively working: serving dynamic requests, compiling code, processing images, encrypting backups, running workers or building containers. A small web application can spend most of its time idle. A build server or busy queue worker cannot.
Choose more CPU when the application does sustained work or when several services run at once. Do not assume that a high core count fixes a memory leak, slow database query or oversized application.
RAM
Memory is the first limit for many VPS workloads. The operating system needs memory. So does your application, its runtime, database, cache and every container you run.
If the server runs out of RAM, Linux starts killing processes or swapping heavily to disk. That feels like a random outage from the user's side. Leave headroom. A server that sits near its memory limit is already too small.
NVMe storage
Storage holds more than application files. Count the operating system, package cache, logs, database data, uploaded files, container images and local backup archives. Logs and databases are common surprises.
Check disk use regularly. Delete data you no longer need. Keep important backups outside the VPS as well. An upgrade to a larger package is the way to add disk capacity, so plan before the disk is full.
Traffic
Traffic is the data transferred to and from the VPS. Downloads, media, API responses, package updates, backups and visitors all use it. A small application with large files can use more traffic than a busy text-based site.
ArkHost publishes a traffic allowance with every plan. Check it against your expected downloads and keep an eye on actual use after launch. Do not buy a plan on the assumption that traffic is unlimited when the plan says otherwise.
A practical way to pick a plan
- One light service: a small API, bot, webhook endpoint, static application server or remote-model agent can start on an entry VPS if its memory use is modest.
- Application plus database: allow memory for both parts, not just the web process. This is where many first deployments are undersized.
- Several containers: add the normal memory and disk use of every container, then leave headroom for updates and logs.
- Builds, media processing or busy workers: prioritize CPU and disk space. These workloads can create short, heavy spikes.
- Growing production service: start with measured requirements, collect metrics and move up before users notice a limit.
Use the real plan limits
Plan sizes and renewal prices are shown on the Linux VPS order page. That page is the source of truth, not an old blog post or a comparison table copied elsewhere.
ArkHost allocates RAM and NVMe storage. Physical CPU capacity is shared, and the product page says so. That is more useful than a vague promise of "unlimited" resources because you can size the server around facts.
