Back-end Development: Everything You Need to Know about Web & App Development  

what is back-end development

Back-end development, also known as server-side development, is the creation of the logic that runs behind the scenes in web applications. 

These days, no one can live without apps. Everyone uses apps all the time, whether it’s to share photos with friends and family, order food, or do banking. Most of the time, these apps make using them simple and smooth. But have you ever wondered how they do that? Thanks are due to the bacckend of the app, which does all the important work that you can’t see. 

Everything that is on the server is part of back-end work. This includes issues with planning and storing data as well as safety. Back-end development builds and takes care of the systems that let users connect with the front end of a website. 

I. What is backend development?  

Back-end development focuses on server-side software or the components of a website that are not visible to the user. With an emphasis on servers, databases, back-end logic, APIs, and architecture, back-end developers guarantee the proper operation of the website. They facilitate code that enables browsers to store, understand, and delete data, as well as communicate with databases.  

how the back-end development works

The backend contains three main parts:  

Database: A database allows us to store a large amount of information in an efficient and structured manner when compared to keeping such information in a text file.  

Server: A server, which is a computer that responds to user requests via the front-end interface (client), computers a result on behalf of the application.  

Application: An application is a computer software that monitors the server for requests, retrieves information from the database, and responds to the server.  

On a team, back-end developers create the framework of a website or mobile application in collaboration with front-end developers, product managers, principal architects, and website testers. Developers of back-end systems must know a wide variety of frameworks and tools, in addition to programming languages like Ruby, Python, and Java. They ensure that the back end responds to requests from the front end promptly. 

II. Why is backend development services important?  

Back-end development is vital to the success of a web application, although it is not readily apparent to end users. It oversees the delivery of the outcomes of the front-end development procedures to site visitors, in addition to managing the business logic of the website.  

1. Security  

A framework provides security from multiple perspectives. Security against external threats and issues, failures, sluggishness, and other detrimental factors may compromise the quality of the application you are developing.    

2. Scalability  

Frameworks possess a high degree of adaptability. Consider the scenario where you have selected the most suitable back-end development framework for your undertaking. Using that framework thereafter would enable you to develop your web application incrementally, progressing from rudimentary to intricate features.  

3. Performance  

The management of a website’s efficacy occurs in the backend. Modern web users expect that pages to load fast, and a substantial portion of back-end development enables this.  

III. How to become a backend developer   

1. What does a back-end developer do?  

Understanding the duties of a back-end developer is the initial requirement for new back-end developers. The responsibility of constructing, maintaining, and troubleshooting the server-side component of a web application falls on back-end developers. They construct the code that enables the delivery of a web page to a user. Whether or not they are working on a complex application, this may be an enormous responsibility.  

Here are some of the daily tasks of a back-end developer:  

– Manage application infrastructure: Configure the networking, servers, and databases that applications will utilize.  

– Design application architecture: Develop the architecture of the application and devise how its components will exchange information.  

– Maintain and interact with databases: These engineers may be proficient in SQL and develop code that facilitates communication between databases and other programming languages.  

– Develop APIs: Application programming interfaces (APIs) facilitate the exchange of data between two applications. This would be a REST API in the case of a website, which supplies the necessary data to the front-end code for it to operate.  

– Write back-end code: The back end of an application contains the majority of its business principles. Code dictates, for instance, which resources are accessible to which users and what occurs to the data submitted by a form visitor.  

– Optimize performance: To guarantee the prompt delivery of websites, back-end developers employ a logging and monitoring mechanism to identify and rectify any performance obstacles.  

– Secure applications: Ensure the encryption of data and connections and the protection of applications against cyberattacks.  

2. Back-end developer skills  

A back-end developer will possess a wide range of technical expertise. They will have experience with operating systems, servers, databases, email, programming languages, etc., and will have a minimum of one programming language knowledge (and likely more). However, they require more than technical expertise to complete the task.  

– Problem-solving: Developers must know more than just how to create code. They must be able to plan and understand how their code will operate before it executes, as well as leverage what they know about programming to address business challenges in creative ways.  

– Communication: Users and business executives leaders must collaborate with developers to create applications that meet their needs. Therefore, this requires developers to comprehend the requirements of non-technical individuals as well as clarify complex processes to them.  

– Industry knowledge: Proficient back-end developers remain abreast of the most recent technological developments to guarantee optimal performance and security for their applications.  

IV. Backend frameworks: Types & Frequently-used frameworks   

1. Types of back-end development frameworks  

a. Client-side web framework  

This framework is user interface-only in nature. The user experience and the simplicity of the application’s operation are both components of the client side.  

b. Server-side web framework  

Back-end functionalities, including but not limited to database manipulation, data, and web server administration, are implemented using this category of framework.  

2. Most frequently-used frameworks

V. Backend development plan for web & app development

1. Discovery and conceptualization  

Duration: 2-6 weeks  

To properly plan the back end, it’s important to understand the business concept, requirements, and processes underlying the software that you intend to develop. Business consultants and software architects debate software kind, anticipated and actual user count, integrations, and on-premises or cloud hosting. Thanks to that, they define the future back end’s functional and non-functional requirements, risks, and restrictions using the knowledge gathered.  

2. Back-end architecture design  

Duration: 4-8 weeks  

The solution’s supporting structure is the back-end system design. If the architecture isn’t well thought out, the whole answer fails, even if the front-end code is very good and the back-end code is very clean. Because of this, picking the right architectural style and explaining it needs a lot of thought. Usually, this process has 5 steps:  

2.1. Analysis  

A software architect meets with you to discuss back-end needs and limitations to identify the must-have and nice-to-have criteria for the final solution.  

2.2. Design and pattern choice  

The architect develops various back-end architectural solutions, classifies them based on the criteria, and selects the one that best meets your demands.  

2.3. Decomposition  

To make back-end implementation easier, the architect breaks the design into smaller parts.  

2.4. Approval  

The architect shows you the main back-end design, tells you about the choices they made about the technology stack (the computer languages, frameworks, and database types), and discusses your back-end hosting options.  

2.5. Documentation  

As a back-end implementation step-by-step guide, the architect tells the development team what parts to build and how to connect them. A project manager (PM) uses this implementation plan to figure out how much work the project will take, pick a development method, and make a specific project schedule.  

3. Back-end software development and QA  

Duration: from 2 months  

Back-end architects plan the layout of the back end, and back-end developers build server-side software with scripts, algorithms, and APIs. This software will be hosted in the cloud or, less often these days, on-premises and will control the whole solution. Then, QA experts work directly with developers to test given code both manually and automatically all the time.  

4. Database development and setup  

Duration: From 1 month  

On its own, database development is not always a separate service. However, back-end devs usually set up the database and APIs as part of the solution they work on. When you put your website in the cloud, cloud database services help spread your data across multiple virtual machines so that you can still access it even if some of the machines are down.  

5. Deployment and Integration  

Duration: 1-3 weeks  

After the implementation is complete, the back-end software and databases may be deployed either on-premises or in the cloud, and they may be integrated with both the client-end and other third-party software. With careful planning of these integrations during the initial phase of the back-end development project, it is unlikely that unforeseen circumstances will result in any disruptions to the launch of your back end.
