Cloud computing is a technology that has changed the way data is stored, computing, and software development is performed. This approach overturns traditional ideas about servers, infrastructure, and access to computing resources. In this article, we will look at how cloud computing affects the way software is developed and used, as well as what benefits it brings.

1. Cloud Computing Fundamentals

Cloud computing is based on the following basic principles:

1. On-Demand Self-Service: Users can independently obtain the necessary resources (computing power, data storage) without the need to interact with service providers.
2. Broad Network Access: Resources are accessible over a network and can be accessed from a variety of devices (e.g., computers, smartphones).
3. Scalability (Resource Pooling): The resources of the cloud provider are pooled and can be scaled depending on the needs of the application.
4. Rapid Elasticity: Resources can be scaled automatically, providing a quick response to changing needs.
5. Measured Service: The resources used can be monitored, controlled and billed depending on the level of usage.

2. Impact on software development

2.1. Changing the approach to development

Cloud computing offers new opportunities for software developers:

• Minimizing infrastructure: Developers can help from the need to maintain their own servers and infrastructure by outsourcing these tasks to cloud providers.
• Flexibility and scalability: The ability to quickly scale applications in the cloud allows them to adapt to a growing number of users and changing workloads.
• Reduced development costs: Using cloud services can reduce software development costs by reducing the need for physical hardware and maintenance costs.

2.2. Improving Availability and Reliability

• Global availability: Applications in the cloud can be accessed by users around the world, improving their availability and reducing time delays.
• Backup and Return: Cloud providers provide automated data backup and recovery capabilities, which increases the reliability of applications.

2.3. Changes to Deployment and Testing Processes

Continuous Integration and Deployment (CI/CD): Cloud computing promotes the use of automated CI/CD processes, which speeds up development cycles and allows for more frequent updates.

Improved testing: In the cloud, you can create separate test environments that can accurately reflect production conditions, which contributes to better software testing.

3. Use of cloud computing for different types of software

3.1. Web Applications

Web applications are often developed using a microservices architecture in the cloud, which provides high scalability and flexibility.

3.2. Big Data and Analytics

Cloud computing enables you to efficiently process large amounts of data and perform complex analytical tasks using distributed computing.

3.3. Mobile Applications

For mobile applications, cloud computing provides opportunities for storing data on remote servers and integrating with cloud services.

Conclusion

Cloud computing has become an integral part of today's IT world, changing the way software is developed and used. They help improve the performance, reliability, and scalability of applications, reduce costs, and simplify development processes. In the future, they will continue to evolve, offering new opportunities for innovation and business process improvement.
