I have a PHP (codeigniter + Mysql) application hosted in a shared web environment. The access of visualization and writing in database have increased a lot in recent times and I am having problems of "throttling" (CPU Throttling) by the hosting server.

I’ve reached the point where I have to change servers due to the slowness the site is undergoing. I have about 10 thousand people connected at the same time and those connected less 8 thousand write something in the database.

Which to choose between Dedicated and VPS?

I have read so much about them that I was confused and would like to know in practice from you.

  • I believe that you should not even consider Dedicated, after all, the best option for you is to go to the cloud, using an AWS EC2 instance or the equivalent on another cloud vendor

  • I agree with @gpupo, there are many good companies that help you scale your system as it grows. (Digitalocean, Linode, Heroku, AWS, etc..)

  • But why use the cloud? Performance, security?

  • Thank you guys. You’ve opened my mind. We’re still studying the cloud issue. :)

Well, first I’ll tell you the differences:

Dedicated Server: Dedicated Servers are physical machines, fully dedicated with high performance hardware to handle high demand.

VPS: A fractional Dedicated Server.

Cloud Server: A cloud-fractionated Dedicated Server, however it is in a remote Server, unlike the VPS it is not in the local hard drive, often it can be migrated from one dedicated to another without anyone noticing, unlike the VPS that only gets in 1 dedicated.

VPS and Cloud Server have the advantage of being able to add or remove memory, cpu quickly.

recommend cloud server.

  • Thanks Felipe Gabriel. You suggest some company "cloud server" in the United States?

  • I recommend the Amazon

A dedicated server or VPS will provide you with acceptable results, the difference is that a dedicated server is a physical machine and the VPS is a virtual machine.

I consider a VPS an option better than a dedicated server in most cases, as its computational resources can be expanded. Unlike the dedicated ones who often have no availability for it.

The performance of a dedicated and significantly superior to that of a VPS, and the maintenance price as well.

Then and your problem has been the shared consumption a VPS will solve your problem as its resources are dedicated, not having the problem of shared hosting.
