Our Work

Microservices with Elasticsearch and API Gateway(Serverless)


This platform is to reduce the operations of elasticsearch to consumers and provide a robust API for complex elasticsearch operations like aggregations, complex searches, getting data on various filters . The results are viewing through angular application in one of the portals of client. 

AWS API  Gateway

Amazon API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. Which can be used to integrate as backend services.


AWS Lambda run code without provisioning or managing servers. You pay only for the compute time you consume the service which is run in serverless fashion function as service.


 Used elasticsearch as primary data source to store and get the data which servers data with blazing speed and can perform aggregations quickly from millions of records.  

 Requirements And Challenges


UI Design

  • Designed front end using angular UI in such a way that it is flexible to use and user friendly.

  • Bussiness Logic

    Build a Robust API on top of AWS Elasticsearch with Native API queries.

  • Complex Aggregations

    Complex Aggregations should be design i.e groupby services and data should be faster should not take more than 5 seconds to return data.

  • Multiple Search Indices

    Search multiple indices for the given input in order to get search results endpoints should not be exposed to public and it should expose to the consuming servers.




  • Built robust API using AWS API Gateway and implemented elasticsearch related business logic in aws lambda using Elasticsearch HTTP API and native API.

  • Since lambda is serverless it can hold more load within the limits assign to the function and servers data to the consumers.

  • Implemented security policies on API gateway and authorizers to validate the origin of request to allow access to data sources.

  • Reduced Complexity of elasticsearch API implementation directly on the servers implemented easily consumable services on top of elasticsearch.

  • Using serverless architecture helps client to reduce cost,HA along with alerting and maintenance.
