I'm learning to manage a VPS

I know about ram, cpu cores and ssd but I don't know which is the most important for a VPS to run perfectly?

Please explain me.

Its depend on the situation if you running many applications at the same time, more ram would help the system running
better SSD is for fast reading, fast loading of applications.

That's a very broad question...

I think a VPS to run perfectly depends on what you are using it for and ensuring that the VPS aspects meet the requirements of the software + the traffic of the site. After wards comes optimizing the setup (control panel, database, apache, etc...).

Yes hardware is a must and critical but that is part of it only.

My recommendation as you know hardware - Learn how to optimize (assuming you already know the basics of your OS)

If you're not sure what kind of resources you need, you can always start with a relatively small VPS and load your site on it. Once your site is up and running, check your resource usage. If it is higher then you would like, then you can always ask your provider to move you up to their next package and seamlessly increase your resources. That's the beauty of VPS's, their instantly scalable, up to the available resources on the physical server.

There's no reason to pay for a larger VPS, if your not sure you need that amount of resources.

It would be a mixture of all things.

Absolutely correct. It usually depends on the purpose you are using your VPS. All of them are required for improving a performance of the server and it should be done depending on your needs.

Selecting the right hard drive for storage on your web hosting and transaction of your business data plays a pivotal role in the stable and easy functioning of your business.

Decision making for storage infrastructure and disk performance always depends upon the usage requirements of the business. Below I will explain the advantages of RAM and CPU, SSD. It will help you compare these disk technologies to arrive on the right decision.

SSD, short for Solid State Disk is a storage device known for its great performance and has zero mechanical moving component.

Advantages of SSD Drives
  • It works very fast with an unbeatable speed as it contains no moving parts
  • It requires low operational cost because it is less prone to any mechanical damage
  • It consumes lesser power hence lesser heat emission resulting in a low carbon footprint
  • It’s a no-noise disk

Advantages of RAM

  • RAM is faster than traditional hard drives (probably 10x faster than an SSD)
  • However, RAM is more expensive and does not store data once the computer is turned off.
  • More RAM = a faster computer that can run more programs at the same time. Less ram is the opposite.
Advantages of CPU

  • Only one CPU command to start I-O•Details of I-O handled by a controller (I-O module)
  • Only one interrupt, when the operation is complete.
  • Overclocking increases a CPU’s performance. A CPU with a clock rate above the manufacturer’s specified rate performs more cycles per second.
  • Underclocking reduces a CPU’s power consumption and heat generation. A CPU with a clock rate below the manufacturer’s specified rate performs fewer cycles per second.

It depends what kind of resources does any particular software application needs. Websites and the software used on we boosting accounts usually take a bit of each and every computing resources. However, some websites and apps need read/write speed, which means they need SSD. Others need more memory or processing power (CPU). There is no generic answer to your question,

SSD works better when you have a faster CPU and more RAM. SSD increases the speed at which the CPU gets the data to be processed. This increase in data transfer to CPU will have no difference in performance if you have a slower CPU. Once your system is booted, RAM makes huge difference is multi-tasking.
So there should be a perfect balance between RAM, CPU and SSD

SSD actually creates difference when running apps and websites , however you will need first go with a smaller VPS plan and then monitor the performance of hosted website or apps as how they are responding , provided you should have optimized your VPS for best performance. If the things are lagging then upgrade your VPS plan accordingly.
