Learn VPS tasks in the order you need them, from signing in and transferring files to configuring the system, deploying apps, restoring backups, and troubleshooting.
Hands-on walkthrough for deploying free Cloudflare CDN acceleration, from domain preparation and DNS cutover to HTTPS, caching, security policies and advanced optimization, plus monitoring methods and a go-live checklist.
These IP labels show up more and more often on VPS sales pages, but many of the claims mix technical facts, industry jargon and marketing packaging. What you can actually verify is usually only ASN, WHOIS/RDAP, rDNS, geolocation database results and historical reputation; what cannot be easily guaranteed includes conclusions like "native IP always unblocks," "residential attributes never trigger risk controls" and "announced IP is always worse." This article breaks these terms apart to help you judge which can be checked and which should not be taken at face value.
Don't rush to install a control panel when you get a new VPS. This article shares a standard 4-step security hardening process: change the SSH port, configure key-based login, enable the UFW firewall, and install Fail2Ban. In just 15 minutes, you can keep your server safe from brute-force attacks and botnet recruitment.
![[Post-Mortem] Next.js Remote Code Execution (RCE) Scare: A Full Attack-and-Defense Record from Abnormal PM2 Logs to a Crypto Mining Trojan](/_next/image?url=https%3A%2F%2Fdirectus-vps.aimazing.site%2Fassets%2F91c19cb1-b3b3-4171-a1d3-f15c28289425.png&w=3840&q=75)
This article provides a detailed post-mortem of a Remote Code Execution (RCE) attack against a Next.js server. By analyzing PowerShell errors and malicious wget download records in the PM2 logs, it confirms that the attacker exploited a Next.js Server Actions or Prototype Pollution vulnerability (such as CVE-2024-34351).
A hands-on walkthrough for putting your site behind Cloudflare's free CDN: change your NS, pick the right cache rules, enable HTTP/2/3, add a simple WAF, and a few notes on the caching and origin-pull pitfalls I've hit along the way.
When a VPS slows down, many people immediately blame undersized specs or overselling by the provider, but the real cause isn't always that resources are genuinely maxed out—it could be the platform, quotas, credits, or the host layer capping you at some limit. This article focuses on the difference between throttling and normal saturation, breaking down the common limiting signals across the CPU, disk, and network layers to help you determine whether the machine is truly insufficient or the instance is already being throttled.
VPS and cloud servers sound similar, but their architectures are completely different. One is single-machine virtualization, the other is a distributed cluster. Only by understanding the difference can you choose the right solution.
KVM and OpenVZ are two different VPS virtualization technologies: one is a full virtual machine, the other is container-based. Understand the difference and choose the right architecture.
When small websites think about stability, they instinctively reach for load balancing, high availability, and multi-server deployment, but in reality the more common problem is that the single-server foundation isn't solid yet and the real bottleneck hasn't reached the point where horizontal scaling is needed. This article breaks things down from the angles of actual traffic for small sites, single-server optimization, availability requirements, and multi-server complexity, to help you judge when you should first do caching, CDN, and single-server scaling, and when load balancing is truly worth adopting.
