Common AWS Questions

Despite AWS’s unparalleled presence in the IaaS space, companies have many questions regarding the world’s largest cloud-based platform. The most common questions revolve around Regions and Availability Zones, which are essential to understanding how to craft successful applications on AWS.


AWS is comprised of 42 “Availability Zones” (AZs) within 16 geographical regions around the world. The standard is between two and five AZs per region. Each region is physically isolated and completely independent of one another. This level of isolation is essential for compliance and data sovereignty requirements, especially with latency-sensitive data that cannot leave a specific geographical region. This is great for maintaining and keeping up with growing regulations, especially in life science organizations or enterprises in the healthcare industry.

Availability Zones

There is a major misconception that there is a single data center per AZ. In fact, there can be multiple data centers in a single zone, connected via fast, private fiber networking, while no two AZs share a single data center. All zones in a region communicate with redundant links. Each AZ uses its own power source and network connection to improve launching a different instance. This level of redundancy benefits companies that require strong mobile engagement or have many users across a large geographic area, helping them load balance and maximize end-user experience

As we dig into the architecture of AWS’s cloud computing platform, we can see how large outages due to improper network maintenance could have immensely debilitating effects on business. Knowing how to avoid these mistakes is crucial for maximizing the potential of the cloud. Understanding how AWS is structured allows enterprises to fully utilize the power of the cloud platform while also gaining insight into how a solution might impact short- and long-term business and networking goals.
