Cloud computing provides on-demand access to a wide range of IT resources, such as computing power, storage, and networking, over the internet. This model allows organizations to scale resources as needed without investing in physical infrastructure. Cloud computing services fall under three primary categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). By leveraging cloud computing, businesses can accelerate innovation, reduce operational costs, and improve time-to-market for new products and services. Additionally, cloud platforms offer tools for automation, data analytics, and machine learning, enabling companies to gain deeper insights from their data. Cloud computing also enhances flexibility, allowing employees to access applications and data from any location, which supports remote work. Security measures, such as data encryption and continuous monitoring, ensure the protection of sensitive information. Cloud computing is a cornerstone of modern IT strategy, providing the agility and efficiency needed to thrive in an increasingly competitive digital landscape.
