What is cloud computing?
- Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing.
- Instead of buying, owning, and maintaining physical data centers and servers, one can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider like Amazon Web Services (AWS).
- Usage: Organizations of every type, size, and industry are using the cloud for a wide variety of use cases, such as data backup, disaster recovery, email, virtual desktops, software development and testing, big data analytics, and customer-facing web applications.
Types of Cloud Computing
- Infrastructure as a Service (IaaS) provides virtualized computing resources like servers, networking, and storage. Offers high flexibility and control over IT resources, allowing users to manage and configure as needed.
- Use Case: Suitable for businesses needing scalable IT infrastructure.
- Platform as a Service (PaaS) delivers a platform allowing users to develop, run, and manage applications without dealing with underlying hardware or software management.
- Use Case: Ideal for developers focused on application development without worrying about infrastructure.
- Software as a Service (SaaS) provides fully managed software applications over the internet. Users only focus on using the software, while the provider handles maintenance and infrastructure.
- Use Case: Commonly used for web-based applications like email or CRM systems.
