5 factors to note that help you buy cheap VPS with good quality


Currently, there are many hosting solutions such as hosting, VPS, private servers, ... With shared hosting, the website will not guarantee performance when sharing server resources with other users. Meanwhile, it would be very resource intensive if you bought a whole server but didn't use it all. Cheap VPS will help us solve this problem. Here are 5 factors you need to keep in mind to be able to buy cheap VPS with the best quality.

RAM

Ram represents the ability to process, read and write data access ... This means that the cheaper VPS the more RAM the ability to access data as possible. Currently, most providers classify VPS packages with RAM from 512MB to 8MB or up to 16GB RAM. Cheap VPSs with higher RAM are usually Cloud VPS. In terms of performance, most RAM types are similar. However, this is only true with physical RAM. You should find out carefully whether your VPS is using physical or virtual RAM to avoid estimating wrong performance of VPS. On average, 1GB of RAM can handle about 10,000 traffic / day and 200 visitors at the same time.

CPU Core

CPU Core is defined as the core or processor core of the CPU. A physical server has a certain number of cores and it will be divided for the VPS. Usually, the higher the number of cores, the better the data processing capacity of the CPU. Because then, the data will be divided into many small packages and distributed to the core processing in parallel at the same time. Each core is capable of processing sequential data packets and a combination of CPU-core will increase the overall processing speed of the system.
 
Hard Disk

Hard drive (hard drive) plays a very important role because it is the storage space of database, source code ... of the website and greatly affects the speed of VPS. Hard drives are divided into two main types: HDD and SSD:

- HDD (Hard Disk Drive): is a traditional drive, used to store data, most PCs in the mid-range segment now use HDD. HDDs are popularly used due to their affordable price and large data storage capacity.

- SSD (Solid State Drive): is a solid state drive, also known as semiconductor hard drive. SSD has better stability, durability, speed and shock resistance than SDD. Currently, HDDs can reach capacities of 12TB or more while SSDs can reach 30TB. At the same time, SSD is capable of accessing data up to 300 times faster than HDD. Therefore, the price of SDD is much higher and not all companies use SSD drives entirely for VPS. If the budget is good, you should choose a cheap VPS to use.

Bandwidth / Transfer

Bandwidth and Data transfer (Bandwidth and data transmission traffic) are two concepts that are often misunderstood. Bandwidth refers to the maximum amount of data that can be transferred in a given period of time. Meanwhile, data traffic represents the amount of digital data that is transferred from one place to another in a specific time, usually 1 second. When buying a cheap VPS, you should pay attention not to be fooled by the provider by these two parameters. The bandwidth should choose the highest level, and the transport flow should reach unlimited (unlimited).
 
Back-up

Backup is always the most important factor, no matter which storage solution you use. Some cheap VPS is not backed up by the provider, you have to perform backup yourself to avoid the risk of data loss.

Virtualization technology

Virtualization technology was born to fully exploit the ability to work of hardware in a server system, helping to divide a physical server into multiple virtual servers. Virtualization acts as an intermediary layer between the hardware system and the software running on it. Currently, VPS uses some of the following popular virtualization technologies:
 
- OpenVZ: OpenVZ (Open Virtuozzo)
is known as an incomplete virtualization technology. This is a virtualization-level system based on a Linux kernel, so all VPS can only run Linux operating system. Advantages: cheap price, because there is no separate kernel, OpenVZ VPS runs fast and efficiently, easily upgrade resources without restarting VPS. Disadvantages: all virtual servers must use the same single core, the allocation of OpenVZ VPS memory is not separate (the memory allocated to VPS can be used by other VPS in case of the other VPS. request). If you are looking for a cheap VPS, this will be a reasonable choice!

- XEN: XEN is a virtualization technology that actually allows running multiple VPS virtual servers on one physical server at the same time. Advantages: unlike OpenVZ, XEN allows each VPS to run its own kernel, so the VPS can run either Linux or Windows. XEN VPS is also allocated independent resources from the server. Cons: XEN VPS requires sufficient physical resources for each VPS so it is usually more expensive than OpenVZ VPS.

- KVM (Kernel-based Virtual Machine): KVM is a full virtual technology, enabling real virtualization on the server hardware platform. As a result, KVM VPS is allocated separate resources, independently of other VPS on the same node. The physical server runs the Linux operating system, but the VPS can run both Linux and Windows. Because of these advantages, KVM VPS is more expensive than OpenVZ VPS.
