But, before signing up, I would recommend you analyze the requirements of your website.
1. Know your website's resource requirements:
In that assessment, hard disk space, CPU, RAM memory resources should be at the top.
2. Operating System:
Choose between the two widely used operating systems.
Linux - Open source and cost-effective
Windows - For .Net works.
3. Managed VPS or Unmanaged VPS:
Unmanged VPS: When you have good technical skills to manage server operations, choose Unmanaged VPS and save your money.
Managed VPS: When you don't have technical skills or wish to avoid the burden of managing server operations, go with managed VPS.
