Self-Hosted n8n on a VPS: Licence, Cloud Prices, Sizing and Security
A buyer's guide to self-hosted n8n: what the Sustainable Use License permits, what n8n Cloud costs instead, the database, queue-mode, pruning and encryption-key settings from n8n's docs, a VPS sizing table with the arithmetic, and when not to self-host at all.

Always-On DDoS Protection vs On-Demand: The Minutes and Milliseconds Each Costs
Always-on filtering can cost latency in peacetime; on-demand costs minutes once an attack starts. From vendor docs and RFCs: minute-long detection windows, BGP /24 diversion, the GRE MTU of 1,476 bytes, DNS TTL arithmetic, hybrid models, and which workloads can afford which.

Carpet Bombing DDoS Attacks: Why Per-IP Thresholds Miss a Whole /24
A carpet bombing DDoS attack spreads traffic across every address in a prefix, so each IP stays under its detection threshold while the total fills shared links. The arithmetic for a /24, what prefix-level detection and upstream filtering add, and what to ask any provider.

DDoS Protected Server in Germany: BSI Data, the Law and What to Buy
Germany adds three things to buying DDoS protection: BSI attack statistics, a computer-sabotage offence and NIS2's 24-hour reporting clock. What each means for a buyer, the BSI list of qualified mitigation providers, and Frankfurt dedicated vs Germany VPS, each with 100 Gbps L4 included.

DNS Amplification Attack: Why Your Firewall Can't Stop the Flood, and How Not to Be a Reflector
A DNS amplification attack uses other people's DNS servers to flood you: spoofed queries, replies with 28 to 54 times the query's payload by CISA's figures. The arithmetic against 1, 10 and 100 Gbps, why your firewall can't help, and how to keep BIND, Unbound or PowerDNS from being a reflector.

VPS DDoS Protection: What a 100 Gbps Filter in Front of a 1 or 10 Gbps Port Means
Every NexonHost VPS now has 100 Gbps of Layer 4 DDoS protection in front of a 1 or 10 Gbps port. What that 10× or 100× ratio means, what it leaves to you (HTTP floods, your own CPU, a NEX traffic quota) and when a dedicated server is the better buy.

SYN Flood Protection on Linux: What the Kernel Can and Cannot Stop
A SYN flood fills the queue of half-open TCP connections on one listening port. What Linux does on its own with SYN cookies, which backlog setting really triggers them, what nftables synproxy adds, the counters that confirm an attack, and where only upstream filtering helps.

Cheap DDoS Protected Dedicated Server: Price per Gbps and the Layer 7 Gap
Since 23 October 2026 the €129-a-month NexonHost build includes 100 Gbps of Layer 4 DDoS protection. What cheap protection often leaves out, the price per Gbps of every paid tier from €149 to €4,499 a month, and why, for a website, a €49 proxy closes the Layer 7 gap for far less than the top tier.

VoIP DDoS Protection: Why SIP and RTP Need a Different Plan
SIP and RTP mostly run over UDP, and a web proxy can carry neither. Here is what network-level DDoS filtering stops, what it can't, the packet arithmetic of a G.711 call, and the SIP-aware controls (pike, ratelimit, fail2ban, ACLs) your own server still needs.

Bring Your Own IP to a Dedicated Server: Your /24, Your ASN and What It Costs
Your own /24 keeps its reputation and allowlists when you change provider, but it needs a route object, an RPKI ROA, an abuse contact and, to qualify for your own ASN, a second upstream. What each step involves, and the 12- and 24-month costs against renting addresses.

Dedicated Database Server Sizing: RAM First, Then Disks, Then Cores
Size a dedicated database server in the order the database uses it: memory for the working set, disks for commit latency, cores last. PostgreSQL and MySQL rules from the official docs, a worked 300 GB example, and which build fits at which price.

Kubernetes Bare Metal: What the Cloud Did for You, and What You Must Bring
A managed Kubernetes service runs the control plane, the load balancers and the disks for you. On rented servers each becomes your job. Here is what the official docs say each piece needs, from etcd quorum to MetalLB and Longhorn, and what a three-server cluster costs.

Private VPN Server: What Renting Your Own Actually Buys You
Renting your own VPN server buys a fixed exit IP for allowlists, remote access to your own networks and a tunnel you control. It does not buy anonymity or another region's streaming. Good and bad fits, transfer arithmetic for 4 TB against unmetered, ports and cost.

ESXi Licensing on a Dedicated Server: What Licence You Need and Which CPUs Run ESXi 8 and 9
Want ESXi on a rented dedicated server? Broadcom sells VMware as subscriptions now, VVF and VCF counted per core with a 16-core minimum per CPU; the free ESXi 8 is non-production only, and Xeon E5 v4 stops at ESXi 8. Core counts for seven builds, from Broadcom's own docs.

Storage Server RAID: Usable Capacity, TiB and What a Rebuild Costs You
Sixteen 20 TB disks are 320 TB raw, but RAID 6 leaves 280 TB and Linux shows 254.7 TiB. Usable capacity and price per TB for three storage server configurations, rebuild floors from drive datasheets, and why RAID 5 on big disks is a bad bet.

Game Server DDoS Protection: Why a Web Proxy Won't Save a UDP Server
Most DDoS advice is written for websites, but game servers speak UDP or their own protocols, which no web proxy can carry. The ports Source, Rust, FiveM, Palworld and Minecraft use, the floods they attract, why Mpps matters more than Gbps, and when a VPS or a dedicated server fits.

Windows VPS RDP: Licences, Sessions and Locking Down Port 3389
Before you rent a Windows VPS for Remote Desktop: when two admin sessions stop being enough and RDS licences start, what the licensed and BYOD images mean, how many users each plan can carry by Microsoft's own sizing, and five steps that keep port 3389 shut.

Blockchain Node Server: Hardware That Keeps Up With the Chain
Ethereum wants NVMe, Solana wants a 2.8 GHz base clock and 256 GB of RAM, and Bitcoin Core asks for far less. We map each project's published hardware requirements, as of 12 October 2026, to real dedicated builds, with the bandwidth arithmetic shown.

Gbps vs Mpps: How to Read a DDoS Protection Spec
A good DDoS protection spec has two numbers, Gbps and Mpps, and small-packet floods usually exhaust the second one first. The Ethernet arithmetic that converts one into the other, how to tell which limit a tier reaches first, where Layer 7 requests fit, and what to ask a provider.

Unmetered VPS Netherlands: What a 1 Gbps Port Moves and What It Costs
An unmetered VPS has no transfer quota, but the port is still a limit. What a 1 Gbps port moves in a month, the traffic level at which each UNEX plan beats its metered NEX twin, what 2 and 4 Gbps ports cost, and the workloads that belong on a dedicated server instead.

Bare Metal vs Cloud: Pricing the Same Server Both Ways
We priced one steady workload both ways in Frankfurt: a 24-core EPYC 9254 dedicated server at €449 a month against the closest AWS m7a instance, with storage, a one-year Savings Plan and internet egress added. The arithmetic is shown, including where the cloud honestly wins.

Server Under DDoS Attack? What to Do in the First Hour
A first-hour runbook for a Linux server under attack: how to rule out a bad deploy or a crawler, the commands that show which layer is failing, what SYN cookies, nftables and rate limits can fix, what only your provider can, and what to ask about null routing.
