Choosing the right VPS size is one of those decisions that looks simple on paper but quickly turns into guesswork when you try to pin down real numbers. Is 1 vCPU enough for WordPress? Does WooCommerce really need 4 GB RAM? What about a growing SaaS app with background jobs, queues and APIs? As part…
Hybrid cloud has moved from buzzword to default strategy for many IT teams. Instead of choosing between “everything in your own data center” or “everything in the cloud”, you combine both: critical systems stay on infrastructure you fully control, while elastic or experimental workloads run on a public cloud platform. When this is designed properly,…
Running out of IPv4 addresses but still need every site to be on HTTPS with its own certificate and brand? That tension is exactly what Server Name Indication (SNI) was created to solve. With SNI, you can host dozens or even hundreds of HTTPS websites on a single IP address without resorting to awkward redirects,…
If you are running a VPS today, treating IPv6 as a “nice‑to‑have for later” is becoming risky. New users are increasingly coming from IPv6‑only mobile networks, IPv4 addresses are getting more expensive, and many CDNs and ISPs already prefer IPv6 when it is available. As part of the dchost.com team, we see this shift in…

DMARC is one of those DNS records that many teams add once and then ignore, until a partner complains their invoices are going to spam or your brand shows up in a phishing campaign. The power of DMARC is not just the policy (p=none, quarantine, reject) but the reports it sends back to you. Those…

Using Object Storage as a Website Origin with S3, MinIO and a CDN
Running a fully static website from object storage is no longer an experimental trick. For many projects it is now the cleanest way to host a site: no web server to patch, no PHP to tune, no database to maintain. You store static files in an S3‑compatible bucket or MinIO, put a CDN in front,…

What “Real HTTPS Behind a CDN” Actually Means
Putting a CDN in front of your website is one of the easiest ways to speed up global visitors and add an extra security layer. But the moment you enable “HTTPS via CDN”, a subtle trap appears: the connection between the visitor and the CDN can be encrypted, while the CDN-to-origin hop stays on plain…

Outbound Email Security on Shared Hosting and VPS: Rate Limits and Abuse Prevention
Outbound email from your website or application looks simple on the surface: a user registers, an order is placed, a contact form is submitted, and an email is sent. But behind that single click, there is an SMTP server, IP reputation, provider‑side limits, and a lot of security controls that decide whether your message lands…
