This is not possible if you are using a shared hosting service. VPS is a good solution for medium-sized businesses that have multiple website systems with large amounts of source code. However, VPS requires user management such as server configuration and system security …

Important technical specifications of VPS

The more RAM you have, the better your data access. You should check whether your VPS is using physical RAM or virtual RAM to avoid making a false estimate of VPS performance. On the server, RAM is the main memory. RAM handles PHP code with PHP software, database queries with MySQL, and supports encoding of data. Therefore, this is a very important parameter.

Currently most VPS services allow you to choose from 512 MB to 16 GB of RAM memory (cloud VPS above 16 GB). Choose the appropriate RAM memory depending on your website traffic and VPS optimization.

Disk space

A disk (HDD) is a storage space that stores operating system installation files and website source code. Drives are currently divided into two types.

HDD (Hard Disk Drive): The most common type of drive used in computers.
SSD (Solid State Drive): Semiconductor hard drive. It is a hard drive that is about 300 times faster than an HDD. VPS with SSD is more expensive than HDD.

Hard drives have a big impact on VPS speed. SSDs are more stable, durable, faster, and more shock resistant than SDDs. If you have a good budget, you should use VPS SSDs.

CPU core

The dedicated server has a specific CPU core and is distributed to VPS Cloud Vietnam. The more CPU cores the VPS has, the faster the data processing will be. Each core can process data packets continuously, and the combination of multiple CPU cores increases the overall processing speed of the system.

swap

Most people don’t use SWAP resources, but using SWAP improves server performance. SWAP is a virtual memory that stores old handle actions when RAM is full (overloaded). SWAP is an independent storage area on the hard drive and is an independent memory. You can create a swap completely with VPS.

backup

Some cheap Vietnam VPS server providers do not provide backup, so you have to do it yourself to avoid data loss.
