When we think of a typical AWS architecture we would assume something like the following diagram but then we realize it's just hosting a WordPress website.
Looks scary right but we could assume we are not just hosting a WordPress Blog but a high traffic news website that gets frequent traffic spikes and high volume traffic. We also need to meet complience requirements and maintain maximum security. That's where AWS can truly deliver value to meet our business expectations.
The Cloud
Cloud platforms such as Amazon Web Services, it is fairly common for virtual machine instances to become unavailable without warning, as the platform is designed to prioritize flexibility and elasticity over single-machine reliability. Hence there is a move towards systems that can tolerate the loss of entire machines, by using software fault-tolerance techniques in preference to hardware redundancy. Such systems also have operational advantages: a single-server system requires planned downtime if you need to reboot the machine (to apply operating system security patches, for example), whereas a system that can tolerate machine failure can be patched one node at a time, without downtime of the entire system.
AWS Global Infrastructure
AWS claims to have the most secure, reliable, and extensive global cloud infrastructure that spans across 123 Availability Zones within 39 Geographic Regions with announced plans for 7 more Availability Zones and 2 more AWS Regions in the Kingdom of Saudi Arabia, and Chile.
Notes
- Game Servers - Where global infrastructure is vital to make sure that players don't fall into an unfair disadvantage because of latency.
- Health Care - Complience with data regulations both in transit and at rest.
