DevOps comparisons: choosing the right server and stack (2026)
Thirteen infrastructure decisions you meet when an application goes into production, each with a one-sentence verdict and a table of criteria. Start from what the application does, then settle the hardware, the hosting type, the software stack and who operates the server. Written for teams hosting in or for Romania.
All DevOps comparisons
Hardware
- Intel or AMD for a dedicated server: which one?AMD wins on uniform cores and memory width, Intel wins on CPU-side AI through AMX, and the only four-NVMe plan runs on a Xeon.
- RTX PRO 4000 or RTX PRO 6000: which GPU for AI?The RTX PRO 4000 is comfortable for models up to about 14 billion parameters; the RTX PRO 6000 is what a 70-billion-parameter model needs.
- NVMe or SATA SSD for a server: which should you pick?NVMe wins for databases, online shops and virtual machines; a SATA SSD stays a fair choice for archives, backups and rarely read files.
- RAID 1 or RAID 10 on a dedicated server: which one?RAID 1 suits two-drive servers; on four equal drives RAID 10 doubles usable capacity and write speed, with the same protection per pair.
Hosting type
- VPS or dedicated server: when does the switch pay off?Start on a VPS while load varies and you grow in steps; move to a dedicated server when you need the whole machine, steady IOPS and physical isolation.
- cPanel hosting or VPS: which one fits your project?cPanel hosting suits WordPress and domain email with no server to run; a VPS is for applications that need root, Docker or processes of their own.
- Dedicated GPU server or pay-per-token AI API: which wins?An API wins at low volume and for frontier models; a dedicated GPU server wins at high, steady volume and when data must not leave your control.
DevOps stack
- Should you use Docker Compose or Kubernetes on your server?Run Docker Compose while everything fits on one server; move to Kubernetes, or its lightweight k3s build, once you need several nodes, failover and autoscaling.
- Nginx, Apache or LiteSpeed: which web server should you use?Nginx for reverse proxying and modern applications, Apache for .htaccess compatibility, LiteSpeed for WordPress with server-level page caching.
- Ubuntu, Debian or AlmaLinux: which distro for your server?Ubuntu for the widest ecosystem and commercial support, Debian for lean stability, AlmaLinux for RHEL compatibility and ten years of security updates.
Operations and security
- Managed or unmanaged server: which one fits your business?Choose a managed server if nobody on your team owns operations; choose unmanaged only if your own people already handle patching, backups and incident response.
- Let's Encrypt or a paid SSL certificate: which do you need in 2026?For almost any site Let's Encrypt encrypts just as well, free; pay only for OV or EV validation, a contractual warranty or vendor support.
- GitHub Actions or GitLab CI/CD: which should you use to deploy to a server?If your code is on GitHub, Actions is the short road; GitLab CI/CD wins when the whole platform must run on your own server in the EU.

How to choose your infrastructure, step by step
Start from the workload, not the hardware
Write down what the application does: brochure site, online shop, API, database or AI model. The type of workload decides more than the processor brand or the core count.
Measure before you choose
Note CPU use, memory in use, disk operations and monthly traffic for the last few months. Without real numbers, every upgrade is an expensive guess.
Pick the hosting type
cPanel for small sites and shops, a VPS for applications that need root access, a dedicated server for heavy workloads or sensitive data, a GPU server for your own AI inference.
Pick the software stack
The operating system, web server and orchestration approach must suit the team that maintains them, not only the application. A stack nobody on the team understands becomes a risk.
Decide who operates the server
Security updates, tested backups, certificates and the delivery pipeline all need a named owner. Decide whether you handle them in-house or receive them as part of your plan.
Common mistakes
- Choosing a server by price per core without knowing whether the application can use several cores.
- Jumping straight to Kubernetes for an application that runs on a single server.
- Treating RAID as a backup and never testing a restore.
- Buying an unmanaged server with nobody assigned to apply security updates.
How 4hosting helps
- DevOps, CyberSecurity and programming hours are included every month: 1 h from cPanel Advanced up, 1–8 h on VPS, 5–10 h on dedicated servers depending on plan and 10 h on GPU servers. You request them from the client panel; they do not carry over, and extra hours are accepted and billed separately.
- AMD and Intel dedicated servers, KVM VPS, cPanel hosting and GPU servers, in a datacentre in Frankfurt.
- Free migration from your current provider, with the configuration checked before the move, and support in English and Romanian.
- NVMe drives on VPS and dedicated servers, unmetered traffic on dedicated servers and L3/L4 DDoS protection included.
Related questions
What is the most important infrastructure decision for a new application?
The hosting type. The gap between cPanel, a VPS and a dedicated server changes who has root access, what software you can run and how isolated your resources are. The processor and the stack come after that choice.
Can I change my decision later?
Yes. A VPS can be enlarged without reinstalling, and a containerised application moves between servers with little effort. The hardest thing to change is an architecture built around one server with no tested backup.
Is support available in English for a team based in Romania?
Yes. Support is in English and Romanian, and your invoices show Romanian VAT as a separate line. Hosting stays in the EU, with a datacentre in Frankfurt.
