Ans. VPS servers are optimized for high performance and reliability, so you can get the most out of your website or web application without worrying about downtime or slow performance. You'll also have access to powerful features like SSD storage and dedicated IPs, which let you focus on building your business rather than managing servers. The best time to switch to VPS is when you need more resources than your current hosting plan can provide. In other words, it's time to move to a VPS plan if you're running out of disk space or RAM because of increased usage or an increased number of users on your site.
