Amazon Elastic Compute Cloud (Amazon EC2). You can use EC2 for your Web Server, runner for your CI. AMI uses yum package installer.

EC2 runs Linux. A specialized Linux called Amazon Linux AMI — Amazon Linux Amazon Machine Image.

EC2 instances has many options, which I recommend you start from On-Demand Instances.

NVIDIA M60 GPU K80, M60, V100
Xilinx UltraScale+ VU9P FPGA

Fixed performance: M5, C5, R5.
Burstable performance: T3

// Example: t3.large, c5d.2xlarge


where [type] => [Family][Generation](Additional Feature)

Large number of generation means newer. C5 is newer than C4.

R5a, M5aa means with AMD CPU.
C5nn means better networking
e for extra capacity
g for Graviton2 processor
d for directly-attached instance storage

A1 only has medium, large, xlarge, 2xlarge, and 4xlarge.

Grow by factor of 2 (vCPU, Memory, price/hour)

vCPU usually ranges from 2 to 96.
Memory usually ranges from 8GB to 384GB.
Network bandwidth ranges from 0 - 25Gbps.

Not all instance supports all sizes.

For real-production use, Memory >= 2GB is a good start (small). And you want an Instance Type that can scale. Seems like large is a more reasonable start because bloated software nowadays.
