Back-end Development: Highlights

Back-end development focuses on creating the server-side logic, setting up databases, and building up communication between a back end and a front end. A back end is an indispensable part for a large number of solutions, including web apps, mobile applications, and IoT ecosystems.

ScienceSoft presents its detailed guide on how to organize a back-end development project and is ready to undertake yours.

  • Back-end development steps: Discovery, architecture design, back-end software development & QA, database setup, deployment & integration.
  • Required talents: Business consultant, back-end architect, back-end developer, project manager, DevOps engineer, QA expert.
  • Sourcing model options: In-house, team augmentation, partial outsourcing, full outsourcing.
  • Cloud services for back-end hosting: Amazon Web Services, Microsoft Azure.
  • Costs: Around $20,000–$50,000 for small/medium-sized back ends. You're welcome to use our configurator to estimate the cost for your case.

Back-end Development Plan

With around 4,000 successful software development initiatives and 250+ back-end developers on board, ScienceSoft is experienced in carrying out effective back-end development projects. As a rule, we break these projects into 5 key steps, described below.

1. Discovery and conceptualization

Duration: 2-6 weeks

To properly plan out the back end, it’s important to understand the business idea, requirements, and processes behind software that you plan to develop or equip with a new back end. For that, ScienceSoft's business consultants and software architects discuss the software type, the existing and planned user count, the integrations, and options for on-premises or cloud hosting. By relying on the gained understanding, they formulate the necessary functional and non-functional requirements, risks, and constraints of the future back end.

ScienceSoft’s tip: In our practice, the unrushed discovery phase (2–3 weeks) has proved the most effective for high-quality budgetary and time estimations, thus preventing additional expenses at the development stage. We also recommend involving front-end developer(s) in the back-end conceptualization process as their input speeds up planning.

2. Back-end architecture design

Duration: 4-8 weeks

The design of the back-end architecture is the backbone of your solution. If the architecture isn’t planned out well, the entire solution fails regardless of the high quality of front-end code or neatness of back-end code. Hence, a lot of consideration needs to be put into choosing and describing the right architecture pattern. This process usually includes 5 steps:

1. Analysis – a software architect discusses back-end requirements and constraints with you to single out the must-have and nice-to-have criteria to the final solution.

2. Design and pattern choice – the architect creates a number of back-end architecture options, organizes them according to the criteria, and chooses the one that fits your needs best.

Best practice: ScienceSoft defines the following back end architecture qualities:

  • Reliability – fault-tolerance, availability, and security.
  • Scalability – ability to allow for a solution’s easy growth and concurrent development.
  • Testability – clean, readable code that is continuously deployed after passing automated testing.
  • Maintainability – flexibility, enabling updates with minimum effort.

3. Decomposition – the architect breaks the architecture down into smaller components, which helps pinpoint reusable elements for simplified back-end implementation.

4. Approval – the architect presents the high-level back-end design to you, shares their decisions on the technology stack (programming languages, framework, and a database type), and discusses the back-end hosting options.

5. Documentation – the architect writes a step-by-step instruction on back-end implementation for the development team with the elements to be developed and integrations to be performed. A PM uses this implementation plan as a base for estimating project efforts, choosing a development methodology, and creating a detailed project schedule.

Best practice: ScienceSoft involves QAs and/or back-end developers in the documentation step for creating test cases and drafting a testing plan early on, which helps ensure consistency with the requirements throughout the project.

3. Back-end software development and QA

Duration: from 2 months

Following the back-end architecture design, back-end developers build server-side software consisting of scripts, algorithms, and APIs that will be hosted in the cloud or, more rarely now, on an on-premises machine and drive the work of the entire solution. Quality assurance experts work hand-in-hand with the developers, continuously performing manual and automated testing of delivered code.

Best practice: ScienceSoft’s teams use frameworks (development tools with ready-made components and libraries) to accelerate back-end development. Our developers see advantages in every framework type: the PHP ones offer extensive tools for web development, .NET helps target any application type running on any platform, back-end JavaScript presents the opportunity of full-stack development, and mature Python and Java frameworks provide the tightest security.

Below, you can see that the frameworks recommended by ScienceSoft can power all kinds of large-scale solutions.

4. Database development and setup

Duration: from 1 month

A database contains all the data used in your solution and communicates it on-demand to the client-end via APIs. In some cases, it can also contain additional business logic for data optimization.

Database development can be a separate service, but in back-end projects, back-end developers usually set up the database and APIs as part of the solution. In case of cloud hosting, cloud database services help data get distributed and replicated across multiple virtual machines so as to enable data access even in case several machines are down.

Best practice: There are two major types of databases: SQL and NoSQL. At ScienceSoft, we opt for SQL databases for simple/medium sized web solutions, web portals, and enterprise apps. NoSQL databases are effective for social networks, IoT, big data, and large e-commerce solutions.

5. Deployment and Integration

Duration: 1–3 weeks

Once your back-end software and databases are implemented, they can be deployed in the cloud or on on-premises servers and integrated with the client-end as well as with other third-party software. If these integrations are thoroughly planned at the first back-end development project stage, no unexpected situations should cause delays of your back end’s launch.

ScienceSoft’s tip: To ensure faster solution launch, ScienceSoft relies on the DevOps practices and sets up a CI/CD pipeline from day one. This helps us make the back end and the entire solution fully operational as soon as the last developed batch is tested and deployed.
