RPAiX Backend Software Development by RPAiX

A back-end in software development is essential for many solutions, consisting of web applications, mobile applications, and IoT ecosystems. The goals of back-end development are building the server-side logic, setting up databases, and establishing communication between the front-end and back-end.

RPAiX provides its in-depth guide on how to organize a back-end development project and is ready to undertake your own.

1. Discovery and conceptualization

Duration: 2-6 weeks

It is critical to fully understand your business requirements and process to plan the backend. First, RPAiX’s software architects and business consultants discuss the software type, existing and planned users, integrations, and the options for cloud hosting. Then, they use this understanding to formulate the functional and non-functional requirements, risk factors, and constraints for the future backend.

RPAiX's tip:

In our experience, the unrushed discovery phase (between 2 and 3 weeks) has proven to be the most efficient for accurate budgetary estimates and time estimations. This prevents additional costs at the development stage. As their input speeds up planning, we recommend that front-end developers be involved in the backend conceptualization.
2. Backend architecture design

Duration: 4-8 weeks

Your solution’s backbone is your backend architecture. Unfortunately, the entire solution will fail regardless of how clean and quality the backend code is. Therefore, choosing and describing the best architectural pattern is essential. This usually involves five steps.

1. Analysis – A software architect will discuss backend requirements with you to identify the final solution’s most essential and desirable criteria.

2. Design and pattern selection – The architect creates many backend architecture options and organizes them according to the criteria. Finally, he chooses the one that best suits your needs.

Best Practice: RPAiX defines the following backend architecture characteristics:

  • Reliability – fault-tolerance and availability.
  • Scalability – The ability to allow for solution’s easy growth, concurrent development, and scaling.
  • Testability Clean, readable code that is redeployed continuously after passing automated testing.
  • Maintenance – Flexibility, enabling updates with minimal effort

3. Decomposition is when an architect reduces the architecture into smaller pieces. This helps to identify reusable elements that can be used in a backend implementation.

4. Approval – The architect presents the high-level backend design to the client, discuss their technology decisions (a framework, programming languages), and discusses the options for backend hosting.

5. Documentation – The architect creates a step-by-step guideline for backend implementation that the development team follows. It includes the elements to be made and the integrations to be done. A PM uses this implementation plan to estimate project effort, choose a development method, and create a detailed project schedule.

Best Practices

RPAiX involves QAs/or backend development in the documentation step to create test cases and draft a testing plan early. This helps to ensure consistency with requirements throughout the project.
3. Backend software development and QA

Duration: from 2 months

Back-end developers create server-side software that follows the back-end architecture design. This includes scripts, algorithms, and APIs. These will be hosted on the cloud or on-premises machines and drive the whole solution. In addition, developers are backed by quality assurance specialists who continuously test the code delivered.

Best Practice

RPAiX teams use frameworks (development tools that include ready-made components or libraries) to speed up back-end development. Every framework type has its advantages: The PHP frameworks offer extensive web development tools,.NET allows for the targeting of any application on any platform, and back-end JavaScript offers full-stack development. Java and mature Python frameworks provide the highest security.
4. Database development and setup

Duration: from 1 month

A database stores all of your data and sends it to the client via APIs. Sometimes, additional business logic can be added to improve data quality.

Database programming can be considered a separate service. However, back-end development usually includes the creation of the database and APIs. Cloud database services enable data to be distributed and replicated across multiple virtual machine instances so that data can still be accessed even when one of the machines is down.

Best Practice

There are two major types of databases: SQL or NoSQL. RPAiX chooses SQL databases for web solutions of small to medium size web portals, enterprise apps, and other web applications. NoSQL databases are useful for social networks, IoTs, big data, and large eCommerce solutions.
5. Deployment and Integration

Duration: 1-3 weeks

After the backend software and databases have been installed, they can either be deployed to the cloud or stored on-premises. The client end can then integrate with them. Your backend should not be delayed if all the integrations have been planned from the very beginning.

RPAiX's tip:

RPAiX’s tip:
RPAiX utilizes DevOps practices and establishes a CI/CD process from day one. This ensures faster solution launches. In addition, this provides that the back end and the solution are fully functional as soon as the last development batch is deployed.
