AWS API Gateway and Elastic: The Perfect Pair for Seamless API Management

What is an API Gateway?

AWS API Gateway is a valuable service that has completely transformed API management. It serves as a portal for developing, deploying, and managing APIs, enabling businesses in custom software development to establish seamless connections between various applications and services. API Gateway ensures the security and reliability of API interactions by providing critical features such as custom API development, authentication, authorization, and traffic control.

Why does the AWS API Gateway integration matter?

AWS API Gateway integration matters because it allows developers to easily and securely connect their APIs to a wide variety of backend services, including AWS services, on-premises applications, and other APIs. This can help developers to build scalable and efficient APIs that can meet the needs of a wide range of users.

Here are some of the benefits of using AWS API Gateway integration:

  • Simplify API development: API Gateway provides a unified view of your APIs and their integrations, making it easier to develop, manage, and monitor your APIs
  • Increase scalability and performance: API Gateway can automatically scale your APIs to meet demand, and it provides a number of features to improve performance, such as caching and load balancing.
  • Improve security: API Gateway provides a number of security features, such as authentication and authorization, to help you protect your APIs from unauthorized access.
  • Reduce costs: API Gateway can help you to reduce the cost of running your APIs by providing a number of features to improve efficiency, such as throttling and usage quotas.
  • Log analysis: Easily delve into API Gateway logs. Our integration allows you to collect and analyze logs for HTTP, REST, and Websocket APIs, assisting you in troubleshooting and gaining valuable insights.
  • Simple integration: Connect your AWS API Gateway to our observability solution with ease. Our simple setup procedure ensures a seamless integration experience.
  • Scalability: Our observability solution scales to meet your needs, whether you have a few APIs or a complex API Gateway landscape. As your API infrastructure grows, you can do so with confidence.

Benefits of AWS API Gateway integration

  • Build serverless APIs: API Gateway can be integrated with AWS Lambda to build serverless APIs that are scalable and cost-effective.
  • Expose existing backend services as APIs: API Gateway can be used to expose existing backend services as APIs, without having to modify the backend services.
  • Create hybrid APIs: API Gateway can be used to create hybrid APIs that connect to both AWS services and on-premises applications.
  • Build APIs for IoT devices: API Gateway can be used to build APIs that can be accessed by IoT devices

What is ElasticSearch?

Elasticsearch is the distributed search and analytics engine at the heart of the Elastic Stack. Logstash and Beats facilitate collecting, aggregating, and enriching your data and storing it in Elasticsearch. Kibana enables you to interactively explore, visualize, and share insights into your data and manage and monitor the stack. Elasticsearch is where the indexing, search, and analysis magic happens.

Elasticsearch provides near real-time search and analytics for all types of data. Whether you have structured or unstructured text, numerical data, or geospatial data, Elasticsearch can efficiently store and index it in a way that supports fast searches. You can go far beyond simple data retrieval and aggregate information to discover trends and patterns in your data. And as your data and query volume grows, the distributed nature of Elasticsearch enables your deployment to grow seamlessly right along with it.

While not every problem is a search problem, Elasticsearch offers speed and flexibility to handle data in a wide variety of use cases:

  • Add a search box to an app or website
  • Store and analyze logs, metrics, and security event data
  • Use machine learning to automatically model the behavior of your data in real time
  • Automate business workflows using Elasticsearch as a storage engine
  • Manage, integrate, and analyze spatial information using Elasticsearch as a geographic information system (GIS)
  • Store and process genetic data using Elasticsearch as a bioinformatics research tool

How to Get Started

Getting started with the AWS API Gateway integration in Elastic Observability is seamless. Here’s a quick overview of the steps:

Prerequisites and configurations

If you intend to follow the steps outlined in this blog post, there are a few prerequisites and configurations that you should have in place beforehand.

  • You will need an account on Elastic Cloud and a deployed stack and agent. 
  • You will also need an AWS account with the necessary permissions to pull data from AWS.
  • You can monitor API execution by using CloudWatch, which collects and processes raw data from API Gateway into readable, near-real-time metrics and logs. Details on the required steps to enable logging can be found here.

Step 1. Create an account with Elastic

Create an account on Elastic Cloud by following the steps provided.

Step 2. Add integration

Log in to your Elastic Cloud deployment.

aws elastic 2

Click on Add integrations. You will be navigated to a catalog of supported integrations.

aws elastic 3

Search and select AWS API Gateway.

aws elastic 4

Then complete the “Configure integration” form with all of the information needed for agents to collect AWS API Gateway metrics and associated CloudWatch logs. AWS credential methods such as access keys, temporary security credentials, and IAM role ARN are all supported. For more information, please see the IAM security and access documentation. You can collect API Gateway metrics, S3 API Gateway logs, or CloudWatch API Gateway logs.

At the bottom of the page, click the Save and continue button.

Step 4: Analyze and Monitor

  • Explore the data using the out-of-the-box dashboards available for the integration. Select Discover from the Elastic Cloud top-level menu.
  • Create custom dashboards, set up alerts, and gain actionable insights into the performance of your API Gateway service.
  • This integration collected the following key monitoring metrics across Rest APIs, HTTP APIs, and Websocket APIs:

Here are key monitoring metrics collected through this integration across Rest APIs, HTTP APIs, and Websocket APIs:

  • 4XXError – The number of client-side errors captured in a given period
  • 5XXError – The number of server-side errors captured in a given period
  • CacheHitCount – The number of requests served from the API cache in a given period
  • CacheMissCount – The number of requests served from the backend in a given period, when API caching is enabled
  • Count – The total number of API requests in a given period
  • IntegrationLatency – The time between when API Gateway relays a request to the backend and when it receives a response from the backend
  • Latency – The time between when API Gateway receives a request from a client and when it returns a response to the client — the latency includes the integration latency and other API Gateway overhead
  • DataProcessed – The amount of data processed in bytes
  • ConnectCount – The number of messages sent to the $connect route integration
    MessageCount – The number of messages sent to the WebSocket API, either from or to the client

Conclusion

The native integration of AWS API Gateway with Elastic Observability represents a significant leap in easing the monitoring and management of your APIs. With this integration, you receive access to a multitude of insights, real-time visibility, and powerful analytics tools in the realm of software development, allowing you to optimize API speed, improve security, and troubleshoot with ease.
