As an expert in cloud computing and infrastructure, I can provide an overview of Amazon Web Services (AWS) and its server count, although it's important to note that the exact number of servers is not publicly disclosed by AWS due to the proprietary nature of their infrastructure. However, I can give you an idea based on the information that is available and some estimations.
AWS is a comprehensive, evolving cloud computing platform provided by Amazon. It has a vast global infrastructure that includes data centers located in various regions around the world. As of the information available up to June 2017, AWS organizes its data center infrastructure into 14 regions, with plans for four more that year. Each region is designed to be isolated from other regions to provide customers with the ability to operate geographically distributed architectures and to control where their data is located.
Within each region, there are multiple, isolated locations known as Availability Zones (AZs). These zones are used to increase the fault tolerance and redundancy of the services hosted on AWS. According to the provided information, each region has from two to five Availability Zones. An Availability Zone is a physical data center facility that is equipped with redundant power, networking, and connectivity, and is operated within a single geographical region.
The number of servers within each data center can vary significantly. The reference suggests that data centers can range from housing as few as 50,000 servers to as many as 80,000 servers. Given the variability and the proprietary nature of AWS's operations, it's challenging to provide an exact count of servers across all data centers.
To estimate the total number of servers, one could use the provided data points to create a rough calculation. Assuming an average of three Availability Zones per region and an average of three data centers per Availability Zone, with each data center housing an average of 65,000 servers (the midpoint of the range provided), the calculation would be as follows:
- 14 regions (as of June 2017) + 4 planned regions = 18 regions
- 3 Availability Zones per region = 54 Availability Zones
- 3 data centers per Availability Zone = 162 data centers
- 65,000 servers per data center = 10,530,000 servers

This would suggest that there could be over 10 million servers in AWS data centers. However, this is a very rough estimate and the actual number could be higher or lower depending on various factors, including the growth of AWS, changes in the number of data centers, and the average server capacity per data center.

It's also important to note that AWS is continually expanding and upgrading its infrastructure. New regions, Availability Zones, and data centers are added regularly, and the technology within each data center is constantly being updated. Therefore, the actual number of servers is likely to be in flux and would require real-time data from AWS, which is not publicly available.

In conclusion, while we cannot provide a precise number of servers in AWS, we can understand that it is a massive, scalable infrastructure designed to meet the needs of a wide range of customers, from startups to large enterprises.

It organizes its data center infrastructure into 14 regions, with plans for four more this year. Each region has from two to five so-called Availability Zones, each of which has from one to as many as eight data centers. Data centers, in turn, range from 50,000 servers to as many as 80,000 servers.Jun 15, 2017read more >>
