Technical articles, infrastructure news, and hosting tips from the voxa.host team.
Your own VPN gives you a clean fixed address and accounts you control, and it makes you responsible for patching it. The two decisions that matter, the setup outline and the honest limits.
Sometimes the requirement is the EU but specifically not Germany. What data residency does and does not give you, the five EU cities we run virtual machines in, and how to test a move for ten cents.
One server in one building is a single point of failure. The cheapest fix is a second small machine somewhere else. Recommended pairs, real monthly totals and a failover drill that costs pennies.
A database that no longer fits in memory does not slow down gracefully, it falls off a cliff. How to size for the working set, what our plans really give a database, and when to move to bare metal.
Latency matters for some strategies and is irrelevant for others. How to tell which you have, how to test two cities for a few cents, and why a restart safe bot beats any hosting decision.
Hosted build minutes get expensive fast. What a runner actually needs, which plan fits which pipeline, where to put it, and the three rules that make hourly machines save money instead of costing it.
The same virtual machine is not the same price in every city. All six plans in all five VPS locations, monthly and hourly, plus what the location fee is and how hourly billing actually works.
A new node is online in Vienna. Every hourly plan from Ion to Titan and every streaming plan from Flux to Vortex can be deployed in Austria again, priced the same as Frankfurt.
Real prices by tier, what actually drives them, and the costs that are not on the pricing page — bandwidth overage, extra IPv4, backups, panel licences and setup fees.
WordPress scales once you stop letting PHP render pages it already rendered. The right order of work, with the Nginx cache-bypass rules that stop you serving one user another's cart.
Deliverability is a reputation problem, not a technical one. The three routes compared, the DNS records that decide everything, and when self-hosting is genuinely justified.
Pick the site closest to most of your users unless a legal or commercial constraint overrides it. Why peering matters as much as distance, and a five-minute decision procedure.
Containers need a real kernel and full root, which is why KVM matters. A production-shaped compose file, sizing guidance, and the Docker firewall behaviour that surprises people.
The whole path on a fresh Linux VPS: install, proxy, TLS, WebSockets, static files, load balancing, rate limits, caching and hardening — plus what Nginx is not the right answer for.
An automated backup that has never been restored is a hypothesis. A routine that runs without you, stores copies the server cannot delete, and gets tested quarterly.
Same flash, different roads to the CPU. Queue depth is the number that matters — here is where NVMe genuinely changes things, and the four cases where it does not.
Two different things sold under one word. What a 1 Gbps port really delivers, why "unmetered" and "unlimited" are not synonyms, and the five questions to ask.
A default-deny firewall in ten minutes, on Debian or RHEL — plus the two protections that stop you locking yourself out, and what a host firewall genuinely cannot do.
Ubuntu LTS and Debian are the two defaults worth arguing between; Alma and Rocky answer the RHEL question. What actually differs — and the one thing that does not.
Scaling means adding capacity without adding fragility. Four decisions, the point where each stops working, and a costed path from one instance to a split architecture.
A firewall cannot stop a volumetric attack — the bandwidth is gone before your server sees the packets. What each layer can absorb, and what to do while one is happening.
Server location and TTFB decide how fast a response can start; page weight decides what users feel. One curl command tells you which problem you have — then fix that one.
Managed hosting manages infrastructure, not your application — the most common misunderstanding about what you are buying. Where the line falls, and the three options between.
Most VPS performance problems are configuration problems. Ten changes that cost nothing, in order of leverage, plus the three signals that mean you genuinely need a bigger plan.
The saving is entirely a function of duty cycle. Four scenarios costed with real hourly rates, plus the five questions to ask about any hourly billing policy.
Server security is a small number of settings applied consistently, not a product. The first thirty minutes on a new server, and where your provider's job ends and yours begins.
A migration is safe when you build and verify the new server before any DNS change. The full sequence — TTL, rsync, hosts-file testing, certificates, cutover and the week after.
Uptime is quoted in nines because the numbers look small either way. What each level actually costs in minutes, what an SLA does and does not promise, and where downtime really comes from.
Shared hosting stops being right when you hit limits you cannot see or change. Five concrete signals, what a VPS changes about each, and the honest cost of moving.
Most VPS buying mistakes start at the price column. Start from peak memory, the shape of your workload and your growth curve instead — with four worked examples.
Virtualisation is decades old. What changed is sub-minute provisioning plus hourly billing — turning servers from assets you own into resources you allocate.
A VPS is a slice of a machine; a dedicated server is the whole thing. The decision is about variance and duty cycle, not raw power — here is where the crossover actually falls.
One physical machine, no hypervisor, no neighbours. What bare metal actually buys you, which workloads justify it, and the three cases where a dedicated server is the wrong purchase.
Hourly VPS hosting bills a virtual server for the hours it exists, not the calendar month. What that changes, which workloads benefit, and the rule most people get wrong about stopped instances.
No contracts, no minimums. Start on an Ion KVM VPS at €0.0063 an hour and move to a monthly bare-metal server the day you outgrow it.
KVM VPS billed hourly, capped monthly · Dedicated billed monthly · No setup fee
