AWShas the concept of a Region, which is a physical location around the world where we cluster data centers. We call each group of logical data centers an Availability Zone. Each AWS Region consists of a minimum of three, isolated, and physically separate AZs within a geographic area. Unlike other cloud providers, who often define a region as a single data center, the multiple AZ design of every AWS Region offers advantages for customers. Each AZ has independent power, cooling, and physical security and is connected via redundant, ultra-low-latency networks. AWS customers focused on high availability can design their applications to run in multiple AZs to achieve even greater fault-tolerance. AWS infrastructure Regions meet the highest levels of security, compliance, and data protection.

AWS provides a more extensive global footprint than any other cloud provider, and to support its global footprint and ensure customers are served across the world, AWS opens new Regions rapidly. AWS maintains multiple geographic Regions, including Regions in North America, South America, Europe, China, Asia Pacific, South Africa, and the Middle East.

An Availability Zone (AZ) is one or more discrete data centers with redundant power, networking, and connectivity in an AWS Region. AZs give customers the ability to operate production applications and databases that are more highly available, fault tolerant, and scalable than would be possible from a single data center. All AZs in an AWS Region are interconnected with high-bandwidth, low-latency networking, over fully redundant, dedicated metro fiber providing high-throughput, low-latency networking between AZs. All traffic between AZs is encrypted. The network performance is sufficient to accomplish synchronous replication between AZs. AZs make partitioning applications for high availability easy. If an application is partitioned across AZs, companies are better isolated and protected from issues such as power outages, lightning strikes, tornadoes, earthquakes, and more. AZs are physically separated by a meaningful distance, many kilometers, from any other AZ, although all are within 100 km (60 miles) of each other.

In addition, the following services usually launch within 12 months of a new Region launch: Amazon Athena, AWS Backup, AWS Batch, Amazon CloudFront, Amazon Cognito, AWS Control Tower, AWS DataSync, AWS CodeBuild, AWS Directory Service, EC2 Image Builder, Amazon Elastic File System (Amazon EFS), Firewall Management Service (FMS), Amazon FSx, Amazon Elastic Kubernetes Service (Amazon EKS), AWS Glue, Amazon GuardDuty, AWS IAM Identity Center, Amazon Kinesis Data Firehose, AWS Lake Formation, AWS License Manager, Amazon Managed Service for Apache Flink (MSF), Amazon Managed Streaming for Kafka (MSK), Amazon MQ, AWS Organizations, AWS Private Certificate Authority, AWS Resource Access Manager (AWS RAM), AWS Resource Groups, Amazon SageMaker, AWS Security Hub, Service Quotas, AWS Storage Gateway, AWS Transit Gateway, and AWS WAF.

Customers can share their interest for local region delivery, request service roadmap information, or gain insight on service interdependency (under NDA) by contacting your AWS sales representative.

AWS Local Zones place compute, storage, database, and other select AWS services closer to end-users. With AWS Local Zones, you can easily run highly-demanding applications that require single-digit millisecond latencies to your end-users such as media & entertainment content creation, real-time gaming, reservoir simulations, electronic design automation, and machine learning.

Each AWS Local Zone location is an extension of an AWS Region where you can run your latency sensitive applications using AWS services such as Amazon Elastic Compute Cloud, Amazon Virtual Private Cloud, Amazon Elastic Block Store, Amazon File Storage, and Amazon Elastic Load Balancing in geographic proximity to end-users. AWS Local Zones provide a high-bandwidth, secure connection between local workloads and those running in the AWS Region, allowing you to seamlessly connect to the full range of in-region services through the same APIs and tool sets.

AWS Outposts bring native AWS services, infrastructure, and operating models to virtually any data center, co-location space, or on-premises facility. You can use the same AWS APIs, tools, and infrastructure across on-premises and the AWS cloud to deliver a truly consistent hybrid experience. AWS Outposts is designed for connected environments and can be used to support workloads that need to remain on-premises due to low latency or local data processing needs.

Apart from the global continental regions, there are also hydrospheric and atmospheric regions that cover the oceans, and discrete climates above the land and water masses of the planet. The land and water global regions are divided into subregions geographically bounded by large geological features that influence large-scale ecologies, such as plains and features.

As a way of describing spatial areas, the concept of regions is important and widely used among the many branches of geography, each of which can describe areas in regional terms. For example, ecoregion is a term used in environmental geography, cultural region in cultural geography, bioregion in biogeography, and so on. The field of geography that studies regions themselves is called regional geography. Regions are an area or division, especially part of a country or the world having definable characteristics but not always fixed boundaries.

In the fields of physical geography, ecology, biogeography, zoogeography, and environmental geography, regions tend to be based on natural features such as ecosystems or biotopes, biomes, drainage basins, natural regions, mountain ranges, soil types. Where human geography is concerned, the regions and subregions are described by the discipline of ethnography.

Global regions are distinguishable from space, and are therefore clearly distinguished by the two basic terrestrial environments, land and water. However, they have been generally recognized as such much earlier by terrestrial cartography because of their impact on human geography. They are divided into the largest of land regions, known as continents and the largest of water regions known as oceans. There are also significant regions that do not belong to either classification, such as archipelago regions that are littoral regions, or earthquake regions that are defined in geology.

Continental regions are usually based on broad experiences in human history and attempt to reduce very large areas to more manageable regionalization for the purpose of the study. As such they are conceptual constructs, usually lacking distinct boundaries. The oceanic division into maritime regions is used in conjunction with the relationship to the central area of the continent, using directions of the compass.

Some continental regions are defined by the major continental feature of their identity, such as the Amazon basin, or the Sahara, which both occupy a significant percentage of their respective continental land area.

To a large extent, major continental regions are mental constructs created by considering an efficient way to define large areas of the continents. For the most part, the images of the world are derived as much from academic studies, from all types of media, or from personal experience of global exploration. They are a matter of collective human knowledge of their own planet and are attempts to better understand their environments.

Regional geography is a branch of geography that studies regions of all sizes across the Earth. It has a prevailing descriptive character. The main aim is to understand or define the uniqueness or character of a particular region, which consists of natural as well as human elements. Attention is paid also to regionalization, which covers the proper techniques of space delimitation into regions.

Human geography is a branch of geography that focuses on the study of patterns and processes that shape human interaction with various discrete environments. It encompasses human, political, cultural, social, and economic aspects among others that are often clearly delineated. While the major focus of human geography is not the physical landscape of the Earth (see physical geography), it is hardly possible to discuss human geography without referring to the physical landscape on which human activities are being played out, and environmental geography is emerging as a link between the two. Regions of human geography can be divided into many broad categories:

D. W. Meinig, a historical geographer of America, describes many historical regions in his book The Shaping of America: A Geographical Perspective on 500 Years of History. For example, in identifying European "source regions" in early American colonization efforts, he defines and describes the Northwest European Atlantic Protestant Region, which includes sub-regions such as the "Western Channel Community", which itself is made of sub-regions such as the English West Country of Cornwall, Devon, Somerset, and Dorset.

In describing historic regions of America, Meinig writes of "The Great Fishery" off the coast of Newfoundland and New England, an oceanic region that includes the Grand Banks. He rejects regions traditionally used in describing American history, like New France, "West Indies", the Middle Colonies, and the individual colonies themselves (Province of Maryland, for example). Instead he writes of "discrete colonization areas", which may be named after colonies but rarely adhere strictly to political boundaries. Among other historic regions of this type, he writes about "Greater New England" and its major sub-regions of "Plymouth", "New Haven shores" (including parts of Long Island), "Rhode Island" (or "Narragansett Bay"), "the Piscataqua", "Massachusetts Bay", "Connecticut Valley", and to a lesser degree, regions in the sphere of influence of Greater New England, "Acadia" (Nova Scotia), "Newfoundland and The Fishery/The Banks".
