In a significant development, Amazon Web Services (AWS) is set to expand its infrastructure with the addition of a new Availability Zone (AZ) in Maryland, slated for completion in 2026. This new addition will enhance the existing AWS US East (Northern Virginia) Region, which was the first AWS Region to be launched and has since experienced substantial growth in customer adoption. The region currently supports a wide range of clients, from burgeoning startups to established multinational corporations. By introducing a new Availability Zone, AWS aims to further bolster its infrastructure, facilitating enhanced redundancy and enabling the creation of highly available applications.
The AWS US East (Northern Virginia) Region is presently composed of six Availability Zones. These zones are connected by high-bandwidth, low-latency network connections, which are essential for maintaining efficiency and reliability. The upcoming Maryland Availability Zone will be interconnected with the existing ones through dedicated, fully redundant fiber networks. This network architecture is crucial for supporting advanced computing workloads, including the burgeoning field of generative artificial intelligence (AI).
Availability Zones are designed to be physically separated by a substantial distance, typically several kilometers apart, yet remain within 100 kilometers (about 60 miles) of each other. This separation ensures that applications distributed across multiple zones are more resilient to localized issues such as power outages or natural disasters like tornadoes and earthquakes. The network performance between Maryland and Virginia within the US East (Northern Virginia) Region is optimized to support synchronous replication, further safeguarding against potential disruptions.
Beyond the Maryland expansion, AWS has ambitious plans for further global infrastructure development. Currently, there are four new AWS Regions under development in New Zealand, the Kingdom of Saudi Arabia, Taiwan, and the AWS European Sovereign Cloud. Additionally, 13 new Availability Zones are in the pipeline, underscoring AWS’s commitment to expanding its global reach and enhancing service reliability.
Recently, AWS has made strides in increasing transparency regarding the geographic locations of its infrastructure. In March, AWS updated its documentation to provide more detailed geographic information about its Regions and Availability Zones. This update includes the addition of the upcoming Maryland Availability Zone to the US East (Northern Virginia) Region’s documentation. The detailed geographic information allows customers to select Availability Zones that best meet their specific regulatory, compliance, and operational needs.
Once operational, the new Availability Zone in Maryland will be accessible through various AWS interfaces, such as the AWS Management Console, AWS Command Line Interface (CLI), and AWS Software Development Kits (SDKs). These tools provide users with the flexibility to manage and deploy their applications seamlessly across the AWS infrastructure.
The addition of the Maryland Availability Zone is expected to be ready for general use in 2026. AWS encourages customers and stakeholders to stay informed by following updates on their Regional News Blog, which provides timely information about infrastructure developments and other AWS news.
For those interested in further understanding AWS’s global infrastructure, detailed information is available on the AWS Global Infrastructure Regions and Availability Zones page.
