Samsung Cloud Platform Service basedof Web Hosting success

Overview

Through a content management system (CMS) that lets us use various themes and plugins, we can create websites easily and quickly.
Among the CMS widely used on large and small websites worldwide, WordPress is a representative example, and it requires a LAMP environment—that is, a Linux, Apache Web Server, MySQL, PHP‑based setup.
This document demonstrates how to quickly and easily set up a WordPress environment using the Virtual Server and MySQL offered by Samsung Cloud Platform, and also considers leveraging CacheStore. I will explain the architecture for building and hosting a website.

Architecture Diagram

1. By configuring a VPC, you can create a basic network environment that provides connectivity between Virtual Servers and between Virtual Servers and the Internet. Within the VPC, separate the areas into Front-end, App, and Data subnets to allow only minimal communication
   
2. The Load Balancer located in the Front-end Subnet distributes web request traffic to the Virtual Servers in the VM Auto Scaling group.
3. Create a Virtual Server or VM Auto Scaling group in the App Subnet, select a Linux image, and launch the server. Install the latest versions of WordPress, Apache web server, PHP, and OPcache on the launched Virtual Server.
4. Select the DBaaS MySQL service to configure the database.
5. In such cases where the database has a high read load, you can configure a CacheStore service in front of the database to provide frequently accessed data as a cache.
6. Configure it so that Virtual Servers can share WordPress data, PHP files, settings, plugins, etc., by using the Object Storage service.
   
   

Use Cases

Start web hosting quickly without the burden of hardware investment

You can use Samsung Cloud Platform services to build instantly when needed and pay only for what you use, without the cost of hardware investment or long lead times.

Web service infrastructure that can flexibly respond to changes in usage

If a usage spike is expected during a specific period, you can respond flexibly by horizontally or vertically scaling resources, such as VM Auto Scaling or changing the Virtual Server type.

Prerequisites

None

Constraints

The use of the VM Auto Scaling service is limited to Virtual Server resources and does not apply to other services within the Compute service family (e.g., Bare Metal Server).

Considerations

Ensuring web server security

To secure a web server exposed to the Internet, you can configure and use the following cloud security solutions.

• A WAF service that monitors website traffic to detect and block attacks.
• DDoS Protection service that detects and blocks DDoS attacks that generate concentrated traffic on web servers to disable the service.
• A web vulnerability assessment service that uses a scanning tool to check for potential vulnerabilities on web pages.
