What is Cloud Development?
Cloud development involves creating applications, services, or platforms that operate on cloud infrastructure instead of traditional physical servers. The cloud offers a flexible and scalable environment that adapts to the changing needs of businesses and developers.
Traditional development often faced limitations such as capacity constraints, high operational costs, and inflexibility in scaling resources. Cloud development addresses these issues by providing:
Elastic scalability, where resources can be adjusted dynamically based on demand.
Pay-as-you-go pricing, where you pay only for the resources you consume.
Global accessibility, with services available to users across the world in real-time.
AWS’s cloud ecosystem encompasses everything from essential infrastructure services like computing power and storage to advanced tools for artificial intelligence, machine learning, and IoT, making it an ideal platform for modern cloud development.
