Introduction to Cloud

• Cloud computing has revolutionized the way businesses and individuals store, manage, and access data and applications.
• With the advent of cloud service providers, such as Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform (GCP), organizations can now leverage the power of the cloud to scale their operations, improve efficiency, and reduce costs.

Services Offered:

1. IaaS (Infrastructure as a Service):
   • Provides virtualized computing resources over the internet, such as servers, storage, and network infrastructure.
2. PaaS (Platform as a Service):
   • Provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure.
3. SaaS (Software as a Service):
   • Delivers applications over the internet on a subscription basis, eliminating the need to install and run the application on individual computers.

Types of Cloud:

1. Private Cloud:
   • A cloud infrastructure operated solely for a single organization, whether managed internally or by a third-party, and hosted either on-premises or remotely.
2. Public Cloud:
   • A cloud infrastructure that provides services over the internet and is open for public use, owned and operated by cloud service providers like Amazon Web Services(AWS), Google Cloud, or Azure.
3. Hybrid Cloud:
   • A cloud infrastructure that combines both private and public clouds, allowing data and applications to be shared between them for greater flexibility and optimization of your infrastructure.
4. Multi-Cloud:
   • A strategy that uses multiple cloud services from different providers, offering increased flexibility and mitigating the risk of vendor lock-in.
5. Community Cloud:
   • A cloud infrastructure shared among several organizations with common concerns (e.g., mission, security requirements, policy), typically managed by a third-party or within one of the organizations in the community.
