The ability to rapidly assemble and reassemble APIs and microservices has become a competitive differentiator across all industries — allowing organizations to pivot business models and deliver amazing customer experiences at speed and scale. Innovative organizations are pushing to become agile and transforming by adopting cloud native technologies that allow them to build more resilient software quickly that easily scales.

Elasticsearch is a JSON-based database leaning heavily towards the unstructured types within the databases available out there. ( Postgres and MySQL are purely structured, while NoSQL is entirely unstructured). It interacts through restful APIs and provides a central unit system combining several datasets arising out of logs, metrics, and application trace data. A quick comparison with relational database management systems (RDBMS) will tell us their similarities.

When it comes to building an API, Rails is an extremely popular programming language choice to build powerful RESTful APIs. In this tutorial, we will build a simple REST API using Rails. The Rails REST API endpoint will allow users to retrieve a credit score rating. Of course, we won’t be linking up to any backend systems to pull a credit score but will instead use a random number generator to generate the score and return it to the user.
