Introduction to AWS Cloud Map and its use cases

In this recipe, we will learn about AWS Cloud Map. We will also learn about the use cases of AWS Cloud Map.

Recipe Objective - Introduction to AWS Cloud Map and its use cases?

The AWS Cloud Map is a widely used service and is defined as a service for discovering cloud resources. it enables users to give their application resources custom names with Cloud Map, and it keeps track of their position as they change over time. Because their web service always discovers the most up-to-date locations of its resources, this improves the availability of their application. Modern applications are often made up of numerous services, each of which performs a specific purpose and is accessible via an API. Each service interacts with a variety of other resources, including databases, queues, object stores, and customer-defined microservices, and it must be able to locate all of the infrastructure resources it relies on in order to function. In most circumstances, users have to manually handle all of these resource names and locations within their application code. All application components, their locations, properties, and health status are tracked by AWS Cloud Map. Users' apps may now query AWS Cloud Map for the locations of their dependencies via the AWS SDK, API, or even DNS. The transition to microservices is made possible by AWS Cloud Map, which serves as the glue that holds all of the business logic together. We use the serverless framework a lot at Peak.ai, therefore we wanted to see if there were any ways to integrate AWS Cloud Map into the serverless framework workflow. However, as the number of dependent infrastructure resources grows or the number of microservices dynamically scales up and down based on demand, manual resource management becomes time-consuming and error-prone. Users can also use third-party service discovery products, but this requires additional software and infrastructure to be installed and managed. Any application resource, including databases, queues, microservices, and other cloud resources, can be registered with custom names using Cloud Map. Cloud Map then checks the health of resources regularly to ensure that the location is accurate. Based on the application version and deployment environment, the application can then query the registry for the location of the resources required.

Benefits of Amazon Cloud Map

  • Every IP-based component of users' applications is constantly monitored by Cloud Map, which dynamically updates the location of each microservice as it is added or withdrawn. This ensures that users' apps only find the most recent location of their resources, boosting the application's availability and thus helping in increasing the application availability. Cloud Map creates a single register for all of the application services, which users may name any way they want. This eliminates the need for their development teams to manually store, manage, and update resource names and locations, or make modifications to the application code and thus boosting the output of developers.

System Requirements

  • Any Operating System(Mac, Windows, Linux)

This recipe explains AWS Cloud Map and uses cases of AWS Cloud Map.

Use cases of AWS Cloud Map

    • It provides a use case for discovering service

Microservices are often built with dynamic resources, such as containers, and may be launched and shut down fast. These resources interact via API and require the application code to provide the location of their dependent resources. However, because each of these resources is dynamic and has continually changed locations, it is difficult for individual resources to keep track of and locate all of their dependencies. Cloud Map is a single, up-to-date registration of service names and locations that makes it easy for microservices to find each other.

    • It provides a use case of integration and distribution continuously

Users must update several configuration files with the location of each service when deploying application code across multiple environments, regions, and versions. Cloud Map keeps a list of service names and locations up to date. Users change the resource's location based on the environment, region, or application version to which they are deploying, and their application will find it automatically.

    • It provides a use case of Health monitoring that is automated

Typically, users' apps are a mix of AWS services and bespoke resources. However, obtaining up-to-date health statuses for all of their application resources is difficult. Cloud Map assists you in accomplishing this goal by maintaining an up-to-date registry of only healthy resources via automatic health checks. This ensures that only healthy endpoints are served traffic.
