4. Storage as a Service (STaaS): Cloud storage services provide scalable storage solutions, allowing users to store and manage data remotely. These services offer flexibility, data redundancy, and security, making them ideal for businesses of all sizes. Examples include Google Drive, Dropbox, and Amazon S3.
5. Function as a Service (FaaS): FaaS, also known as serverless computing, allows developers to build and run applications without managing servers. Functions are executed in response to events, such as HTTP requests, and are scaled automatically based on demand. Examples include AWS Lambda, Azure Functions, and Google Cloud Functions.

Types of Cloud Computing

1. Public Cloud: Public cloud services are delivered over the internet by third-party providers and are available to anyone who wants to use or purchase them. Public clouds are owned and operated by cloud service providers and offer scalable, cost-effective solutions. Examples include AWS, Microsoft Azure, and Google Cloud.
2. Private Cloud: A private cloud is a cloud infrastructure dedicated to a single organization. It can be hosted on-premises or by a third-party provider. Private clouds offer greater control over data, security, and compliance, making them suitable for organizations with specific regulatory requirements.
3. Hybrid Cloud: Hybrid cloud combines public and private cloud environments, allowing data and applications to be shared between them. This model offers greater flexibility and optimization by leveraging the benefits of both public and private clouds. Businesses can keep sensitive data in a private cloud while using the public cloud for less critical operations.
4. Multi-Cloud: Multi-cloud refers to the use of multiple cloud services from different providers to avoid dependency on a single vendor. This approach allows businesses to optimize costs, performance, and reliability by choosing the best services from different providers.
