The main concern is connectivity. When someone requests a mobile score, we need to query the backend DB using prospect numbers. This involves going from AWS to the Oracle DB in Oracle Cloud, fetching data through SQL queries, and then feeding it back to the model running on AWS. This process takes a considerable amount of time. It's like dealing with connectivity issues because of the direct connection. Although I find AWS API Gateway better than Oracle in many aspects, the network connectivity challenges force us to consider using Oracle API Gateway for our new product, LOS (Load Origination System). This new product will involve extensive interaction with the databases, and we cannot afford network connectivity issues. This is the only drawback I've encountered. Even though AWS API Gateway is better in several respects, we are leaning towards Oracle API Gateway due to its compatibility with our Oracle backend databases. Traditionally, enterprise databases are Oracle databases, and that's why we work with Oracle Cloud. We're also exploring MuleSoft, which offers a wide range of features and services, although cost is a concern.
