The primary purpose of modern app development is to create and deliver applications with greater speed, flexibility, and security. Modern application development is an approach that enables organizations to innovate rapidly by using cloud-native architectures with loosely coupled microservices. The following are some common requirements that apply to any modern application:

• Scale gracefully from tens to thousands to millions of users and handle increasing volumes of data—without needing to redesign the app in the future.
• Provide the lowest latency and highest throughput required for the best possible user experience.
• Rely on modern automation tools and methods for build and deployment processes.
• Avoid bottlenecks caused by the need for manual tasks.

Modern applications are built in small chunks called microservices that can be incrementally pushed to testing and deployment. They are highly available globally, manage petabytes of data or more, and respond in milliseconds. Developers and IT organizations build them with a combination of modular architecture patterns, serverless operational models, DevOps, DevSecOps, low-code, and agile development processes. The following are some of the benefits of modern application development:

• Greater scalability, portability, resiliency, and agility.
• Faster time-to-market.
• Improved customer experience.
• Reduced costs.
• Increased security.

In summary, the primary purpose of modern app development is to create applications that are highly scalable, flexible, and secure, and that can be delivered quickly to meet the needs of customers and businesses.
