Why is Software Engineering Needed?

• Software engineering was introduced to address the issues of low quality software projects. It is essential for creating high-quality software that meets the needs of users.

Scalability - the ability of a system to handle a growing amount of work or its potential to accommodate growth

Maintainability - the ease with which a software system can be modified, enhanced, or repaired, ensuring long-term efficiency and adaptability

Reliability - ability to function correctly and consistently under expected conditions for a specific period

Why is software engineering needed for scalability?

• Scalability is a key factor that determines the ability of software application to accommodate an increase in workload or data without impacting performance

• Software Engineering principles facilitate the development of scalable software that can grow with increasing demands. It also allows for easy adaptation to changing requirements and technologies.

Key Software Engineering Principles for Scalability

Modular Design - breaks the system into independent components for easy scaling and updates

Scalable Architecture - uses microservices, cloud computing and load balancing to handle growth efficiently

Automation - automates deployment, testing, and scaling processes to ensure smooth growth

Monitoring and Analytics - tracks performance and identifies bottlenecks for continuous optimization

Decoupling - separates system components so they can scale independently without affecting other parts

Redundancy & Fault Tolerance - ensures backup systems are in place to handle failures

Caching - stores frequently accessed data to reduce database load and improve speed

Why is software engineering needed for maintainability?

• Software engineering principles provide structured approaches to designing and maintaining software that remains adaptable, efficient, and cost-effective over time.

• Maintainability enables developers to fix bugs, add features, and update systems with minimal risk

Why is reliable software important?

• It is vital to have reliable software in order to ensure that these systems work seamlessly, reducing interruptions, data loss, and user dissatisfaction.

• When a system is reliable, it minimizes failures, ensuring users can depend on it to perform its tasks without unexpected errors.
