I have a question regarding the VPS mode that are popularly marketed nowadays. I understand that a virtualization provides dedicated or theoretically guaranteed resources by the vendor, regardless of technology, KVM; OpenVZ; Xen or other, the concept is always the same. With the arrival and popularization of the Cloud, this "clustering" facilitated the commercialization of virtual servers since this distribution left everything very scalable, they are setting up a network of clusters and calling the cloud. There are a number of companies offering VPS with very good features, but I've always wondered if these high-end plans deliver what they really should.
The famous Digital Ocean for example, it has VPS plan with: 48GB RAM, 12 vCores, 960GB SSD and 8TB bandwidth. All this for $ 240.00 (approx $ 900.00) monthly. Has anyone had - or has - any experience with using such plans, and has been able to enjoy all that power? I ask this because I have doubts if in a distribution architecture, it could present instability when reaching the limit of these resources.
With $ 250.00 you can hire a good dedicated in a reliable company. But will the cloud structure of redundancy and availability have as good a result as a dedicated one of the same power? Of course in theory everything is always beautiful and functional, but it is known how these companies operate.
I'm no expert, far from it, so I wonder if a staggered VPS like Digital Ocean is worth compared to a dedicated VPS of the same power.
Thanks for your attention.
