FAQ

What is the Software Development Life Cycle (SDLC)?

The SDLC is a process used to plan, develop, test, and deploy a software system. It typically includes stages such as requirements gathering, design, implementation (coding), testing, deployment, and maintenance.

What is Agile methodology?

Agile is a set of principles for software development under which requirements and solutions evolve through the collaborative effort of cross-functional teams. Agile methodologies promote iterative development, where requirements and solutions are developed incrementally and changes are embraced at any stage.

What is Version Control and why is it important?

Version control is a system that records changes to files over time so that specific versions can be recalled later. It is important because it helps multiple developers to collaborate on a project, track changes, and revert to previous versions if necessary. Git is a popular version control system.

What is Continuous Integration/Continuous Deployment (CI/CD)?

CI/CD is a method to frequently deliver apps to customers by introducing automation into the stages of app development. The main concepts are continuous integration, continuous delivery, and continuous deployment. CI/CD helps to detect and address problems early in the development process.

What is the difference between front-end and back-end development?

Front-end development involves creating the visual and interactive parts of a website or application that users interact with. Technologies include HTML, CSS, JavaScript, and frameworks like React or Angular. Back-end development deals with the server side, managing databases, server logic, and application integration. Technologies include languages like Java, Python, Ruby, and frameworks like Node.js or Django.

What are RESTful APIs?

RESTful APIs (Representational State Transfer) are web services that use HTTP requests to GET, PUT, POST, and DELETE data. They are stateless, meaning each request from a client to the server must contain all the information needed to understand and process the request.

What is Test-Driven Development (TDD)?

TDD is a software development approach where tests are written before writing the bare minimum of code necessary for the test to pass. This approach helps ensure that the code is tested continuously and that the final product is more reliable and bug-free.

What is DevOps?

DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). It aims to shorten the systems development life cycle and provide continuous delivery with high software quality. DevOps practices include automation of processes, continuous monitoring, and collaboration between developers and operations teams.

How do you ensure the security of an application?

Ensuring the security of an application involves multiple practices such as:

• Implementing secure coding practices.
• Conducting regular code reviews and security audits.
• Using encryption to protect sensitive data.
• Employing authentication and authorization techniques.
• Applying patches and updates promptly.
• Monitoring applications for security threats and vulnerabilities.

What is a microservices architecture?

A microservices architecture is a design approach in which a single application is composed of many loosely coupled and independently deployable services. Each service has a specific business function and can be developed, deployed, and scaled independently, making the architecture flexible and scalable.
