Recipe Objective - Explain the features of AWS Cloud Map?

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 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is constantly monitored by Cloud Map, which dynamically updates the location of each microservice as it is added or withdrawn.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 the features of AWS Cloud Map.

Features of AWS Cloud Map

    • It discovers resources via API calls or DNS queries

Cloud Map makes it possible for users' apps to find any web-based service using the AWS SDK, API calls, or DNS queries. Cloud Map uses DNS to offer resource locations for IP addresses or IP: port combinations using IPv4 or IPv6. Cloud Map may return URLs or ARNs, as well as IP addresses and IP: port pairs, using the discovery API.

    • It offers service naming that has been simplified.

AWS Cloud Map allows users to provide the application's services with simple custom names. Amazon Elastic Container Service (ECS) tasks, Amazon EC2 instances, Amazon S3 buckets, Amazon DynamoDB tables, Amazon Simple Queue Service (SQS) queues, and any other cloud resource are all examples of this.

    • It assigns the custom attributes

Custom attributes for each resource, such as location and deployment stage, can be defined in Cloud Map. This gives users the freedom to tailor their deployment to different areas or conditions.

    • It provides access control

Only authenticated services can discover resources within the registry and receive the location and credentials for those resources, thanks to Cloud Map's integration with AWS Identity and Access Management (IAM).

    • It provides automatic health checks

On discovery queries, Amazon Route 53 health checks ensure that only healthy endpoints are returned. Cloud Map will always have an up-to-date registration of healthy resources as a result of this.

    • It provides AWS container services that are deeply integrated.

Amazon Elastic Container Service (ECS) and Amazon Elastic Service for Kubernetes (EKS) services and tasks can be automatically registered and updated in Cloud Map. ECS automatically registers tasks for your service as resources with Cloud Map, and they are discoverable within five seconds.

    • It provides the change that spreads quickly.

When you use API-based discovery, you can get updates on the locations and attributes of your resources in less than 5 seconds.

    • It provides a fully managed environment

AWS Cloud Map takes care of setting up, updating, and managing users' service discovery tools and software.
