Region selection
The choice of Region for your workload significantly affects its KPIs, including performance, cost, and carbon footprint. To improve these KPIs effectively, you should choose Regions for your workloads based on both business requirements and sustainability goals.

Choosing AWS Regions for your OpenSearch Service workload involves considering various factors to optimize performance, availability, costs, and carbon footprint. To improve these KPIs effectively, you should choose your OpenSearch Service Region for your workloads based on both business requirements and sustainability goals.
The following are some key considerations when selecting AWS Regions for OpenSearch Service:
-
Renewable energy: Choose Regions near Amazon renewable energy projects and Regions where the grid has a published carbon intensity that is lower than other locations (or Regions).
-
Proximity to users: Choose a Region that is geographically close to your users. Test the network latency between your end user locations and each AWS Region that meets your sustainability goals. Selecting a Region with low latency is crucial for applications where user experience is a priority.
-
Compliance and data residency: Consider regulatory requirements and data residency constraints. Verify that the AWS Region you choose complies with legal or regulatory restrictions on data storage and processing. Some industries or countries may have specific regulations that dictate where data must be stored.
-
High availability and fault tolerance: Enhance fault tolerance and high availability by distributing your Amazon OpenSearch Service domain across multiple Availability Zones within a Region. This makes your workload resilient to failures in a single Availability Zone. Choose a Region that provides multiple Availability Zones for redundancy. Improve customer experience by taking advantage of the cross-replication feature of Amazon OpenSearch Service to create clusters across different geographical Regions.
-
Service and feature availability: Check if the AWS Region supports all the features and services you intend to use with OpenSearch Service. Some AWS services and features might be available in specific Regions first before being rolled out globally. Verify that the necessary services and features for your workload are supported in your chosen Region.
-
Global applications: If your application serves a global user base, evaluate whether a multi-Region setup is necessary. This involves deploying OpenSearch domains in multiple AWS Regions and using cross-cluster replication to provide optimal performance and availability for users in different geographic locations.
