Best practices
The following are a few best practices for integrating with Amazon Location Service.
Resource management
To help effectively manage your location resources in Amazon Location Service, consider the following best practices:
-
Use regional endpoints that are central to your expected user base to improve their experience. For information about region endpoints, see Amazon Location supported regions.
-
For resources that use data providers, such as map resources and place index resources, make sure to follow the terms of use agreement of the specific data provider. For more information, see Terms of use and data attribution.
-
Minimize the creation of resources by having one resource for each configuration of map, place index, or routes. Within a region, you typically need only one resource per data provider or map style. Most applications use existing resources, and do not create resources at run time.
-
When using different resources in a single application, such as a map resource and a route calculator, use the same data provider in each resource to ensure that the data matches. For example, that a route geometry you create with your route calculator aligns with the streets on the map drawn using the map resource.
Billing and cost management
To help manage your costs and billing, consider the following best practice:
-
Use monitoring tools, such as Amazon CloudWatch, to track your resource usage. You can set alerts that notify you when usage is about to exceed your specified limits. For more information, see Creating a Billing Alarm to Monitor Your Estimated AWS Charges in the Amazon CloudWatch User Guide.
Quotas and usage
You AWS account includes quotas that set a default limit your usage amount. You can set up alarms to alert you when your usage is getting close to your limit, and you can request a raise to a quota, when you need it. For information about how to work with quotas, see the following topics.
-
Create CloudWatch alarms for Amazon Location Service metrics
-
Visualizing your service quotas and setting alarms in the Amazon CloudWatch User Guide.
You can create alarms to give you advance warning when you are close to exceeding your
limits. We recommend setting alarms for each quota in each AWS Region where you use
Amazon Location. For example, you can monitor your use of the
SearchPlaceIndexForText operation, and create an alarm when you exceed
80 percent of your current quota.
When you get an alarm warning about your quota, you must decide what to do. You might be using additional resources because your customer base has grown. In that case you may want to request an increase to your quota, such as a 50 percent increase in the quota for an API call in that Region. Or, maybe there's an error in your service that causes you to make additional unnecessary calls to Amazon Location. In that case you'd want to solve the problem in your service.
