In this post, we’ll explore the importance of modernizing your data infrastructure to speed up application development and iteration, as well as key features and benefits of using MongoDB Atlas on AWS to get the job done. Additionally, we’ll review a case study of one organization’s modernization journey.

Competitive advantage often lies in a company’s ability to create modern customer experiences. But for many, an unwieldy data infrastructure can get in the way and prevent innovation.

To build and evolve applications quickly, gain timely access to key insights, and ultimately stay ahead of the pack, many companies will need to modernize their data infrastructure.

Most modernization projects begin with leaving (at least part of) the past behind. Many business applications have traditionally been built on legacy systems based on relational database management systems (RDBMS), which store data in a rigid, table-based (or tabular) format. Unfortunately, these rigid data structures are hard to change and thus slow down application development.

Tabular data models also aren’t intuitive and don’t match the way most developers think and code at the application layer: a single logical entity, like a customer, may be spread across dozens of tables.

Furthermore, most relational databases don’t have a distributed architecture built in. Without automatic failover, an application’s downtime risk is increased, and without horizontal scaling, the data layer is expensive and complicated to grow with a global customer base. The consequences of an unwieldy data infrastructure are manifold.

Developer productivity is inhibited as they spend time trying to innovate on top of a data model that doesn’t match application logic and is hard to evolve. Administering databases is onerous, especially if you need to build in your own resilience and scaling—this is even more time-consuming if you’re managing your own infrastructure on-premises.

Some organizations will attempt to add additional data systems alongside their RDBMS for new capabilities, only to encounter new problems around data integration and movement, data duplication, and complex architectures, resulting in a fragmented development experience. The net effect of a poor, out-of-date data infrastructure is that innovation slows to a crawl.

The solution? Adopting a global cloud database service that can help you build, run, and improve your modern applications.

MongoDB Atlas on Amazon Web Services (AWS) lets you build applications that are highly available, performant at a global scale, and compliant with the most demanding security and privacy standards. When you use MongoDB Atlas on AWS, you can focus on driving innovation and business value, instead of managing infrastructure.

Softinstigate: Winning the Fast-paced Italian Marketplace

Softinstigate is a highly specialized services company focused on providing cutting-edge engineering solutions for clients who want to accelerate their software development and digital transformation.

With deep expertise in enterprise data products, CEO Andrea Di Cesare and Co-Founder Maurizio Turatti have always understood the critical role that an agile database plays in delivering such success. When they found themselves spending too much time on technical fixes to keep servers and databases running instead of solving their clients’ business problems, they knew they had to make a change.

Eager to accelerate development cycles, meet demand, and win contracts in their home country of Italy, where many small businesses are able to move at lightning speed, Andrea and Maurizio chose to leave the inflexibility of relational databases behind in order to overcome its limitations and succeed in a new paradigm.

With the rapid ascension of web and mobile apps, the Softinstigate founders knew they could easily manage data from such sources in a document database. They made the decision to build a Java app server on top of MongoDB.

RESTHeart: A Ready-to-use REST API for MongoDB

Softinstigate developed RESTHeart, a ready-to-use REST API for MongoDB, and the company now deploys the majority of its products and services on MongoDB Atlas running on AWS.

RESTHeart is a stateless REST API microservice that uses simple HTTP calls to unleash the power of MongoDB. It is written in Java and requires no server-side coding, thereby freeing developers to focus on developing innovative, value-adding apps.

Many of Softinstigate’s customers are running RESTHeart on Amazon Elastic Container Service (Amazon ECS), as a simpler alternative to managing a Kubernetes cluster. The architecture also includes a Multi-Availability Zone Application Load Balancer on top of the ECS cluster to get automatic load balancing and blue/green hot deployments.

Together with MongoDB Atlas always on and globally available clusters, RESTHeart’s architecture removes any single point of failure on the platform.

Softinstigate’s RESTful design strategy was to model sessions and transactions as first-class REST resources. In MongoDB, an operation on a single document is always atomic, and that’s one of the reasons Softinstigate opted to model data using embedded documents instead of creating relationships between multiple documents and collections.

Softinstigate gained more advantages with the launch of MongoDB 4.0, including atomicity and strong consistency across databases, collections, documents, and shards using transactions.

Virtually, any device can send an HTTP request to MongoDB through the API. RESTHeart sends queries to MongoDB using the Java driver and sends back the HTTP response as a JSON message.

Softinstigate is quick to point out that in addition to JSON, RESTHeart can accommodate virtually any type of content.

“If you want to have replication with other databases it is a much larger effort. Failover and upgrade are easy with MongoDB; to scale a single node up and down, it’s a click of the mouse. We take this level of convenience for granted with MongoDB.” – Co-Founder Maurizio Turatti

For instance, one Softinstigate customer experiences extreme peak loads with its data traffic, and MongoDB’s Autoscale feature scales up to handle them.

In addition to the standard REST API, starting from version 6 RESTHart also offers complete GraphQL and Websocket APIs on top of MongoDB.

Use Case: Executing RESTful Multi-document Transactions

The following simple use case shows the power of RESTful multi-document transactions to execute transactions using very little code.

The client uses an Angular app that interacts with the server through simple HTTP requests. The server stack comprises MongoDB and RESTHeart.

RESTHeart exposes the REST API, which meets all the client’s needs to read and write data, both normally and transactionally. All of this occurs with no server-side code. The backend is a standard installation of RESTHeart that provides the API out of the box.

Figure 2 is a user screen view in RESTHeart. On the left side are buttons to control the execution of the transaction step-by-step. On the right, you can see request logs showing interactions between the client and server describing each REST request.

For this use case, data is stored in two collections: Palettes and Colors. Each Palette is composed of five Colors and is implemented by a property in Colors that references the corresponding palette.

Creation of the Palette requires writing six documents across the two collections, and the application writes them through a multi-document transaction to enforce data consistency.

As shown in Figure 3, creating this app required only 37 lines of code.

Today, all Softinstigate customer deployments are on MongoDB-driven RESTHeart running in the cloud on AWS.

The company is now leveraging the capabilities of MongoDB Atlas to grow and maintain its existing revenue streams while expanding up-market. They haven’t touched a relational database in six years.

Highlights include:

• Nearly 100% availability supporting Softinsitgate’s dual go-to-market strategy.
• Advantages in agility and resource savings.
• Accelerates clients’ time to market by up to 20x.
• Simple MongoDB-AWS architecture creates trusted relationships, especially in Italy’s fast-moving marketplace.
• 100m+ downloads.
