    Hello, It difficult to know for sure how much each website will use, so there's no way to provide a definitive guide on the required resources you should make available to the instance. You can find the "Minimum" requirements for cPanel at: Installation Guide - System Requirements - Version 66 Documentation - cPanel Documentation Thank you.

    Folks, My cPanel server provides web hosting and email services for 100-200 sites. Many sites use WordPress or Joomla, so Apache, PHP and MySQL performance needs to be optimized. Which Amazon EC2 instance family would be the best fit? Amazon EC2 instances are grouped into 5 families: General Purpose, Compute Optimized, Memory Optimized, GPU, and Storage Optimized. General Purpose Instances have memory to CPU ratios suitable for most general purpose applications and come with fixed performance (M4 and M3 instances) or burstable performance (T2); Compute Optimized instances (C4 and C3 instances) have proportionally more CPU resources than memory (RAM) and are well suited for scale out compute-intensive applications and High Performance Computing (HPC) workloads; Memory Optimized Instances (R3 and R4 instances) offer larger memory sizes for memory-intensive applications, including database and memory caching applications; GPU Compute instances (P2) take advantage of the parallel processing capabilities of NVIDIA Tesla GPUs for high performance parallel computing; GPU Graphics instances (G3) offer high-performance 3D graphics capabilities for applications using OpenGL and DirectX; Storage Optimized Instances include I3 and I2 instances that provide very high, low latency, I/O capacity using SSD-based local instance storage for I/O-intensive applications and D2, Dense-storage instances, that provide high storage density and sequential I/O performance for data warehousing, Hadoop and other data-intensive applications. When choosing instance types, you should consider the characteristics of your application with regards to resource utilization (i.e. CPU, Memory, Storage) and select the optimal instance family and instance size. Thanks, Jim
