What is Cloud Computing?
AWS cloud computing refers to the delivery of computing services including the server, storage, database, networks, software, analytics, and more over the internet (cloud) to offer faster innovation, flexible resources, and economies of scale. The own and maintaining the physical data center and server users can access technology service on demand from a cloud provider on a pay as.
TYPES OF CLOUD
In AWS cloud computing there are several types of clouds, each offering different deployment models and service offerings to meet the needs of users and organizations:
- Public Cloud: Public clouds are owned and operated by third-party cloud service providers, making resources such as virtual machines, storage, and applications available to the general public over the Internet. Users typically pay for the resources they consume on a pay-as-you-go basis, making it a cost-effective option for small to medium-sized businesses and startups. Examples of public cloud providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).
- Private Cloud: Private clouds are dedicated cloud environments used exclusively by a single organization. These clouds can be hosted either on-premises within the organization’s data centers or by a third-party service provider. Private clouds offer greater control, security, and customization options compared to the public cloud making them suitable for organizations with specific compliance or regulatory requirement such as healthcare or finance industries.
- Hybrid Cloud: Hybrid clouds combine elements of both public and private clouds, allowing organizations to leverage the benefits of both deployment models. In a hybrid cloud environment, workloads can move between public and private clouds as needed, providing greater flexibility, scalability, and cost-efficiency. Hybrid clouds are ideal for organizations with fluctuating workloads or those looking to maintain sensitive data on-premises while utilizing the scalability of the public cloud for other workloads.
- Community Cloud: Community clouds are shared infrastructure environments that are tailored to meet the specific needs of a group of organizations with shared interests or requirements. These clouds are typically managed by a third-party provider and are used by multiple organizations that have similar security, compliance, or performance requirements. Community clouds enable collaboration and resource sharing among organizations within the same community while still offering a level of customization and control.
- Multi-Cloud: Multi-cloud refers to the use of multiple cloud services or platforms from different providers. Organizations may choose a multi-cloud strategy to avoid vendor lock-in, mitigate risks associated with relying on a single provider, and take advantage of best-of-breed services from different cloud vendors. Managing multiple cloud environments can be complex, but it offers flexibility, redundancy, and optimization opportunities for organizations with diverse requirements.

How AWS works
AWS cloud computing (Amazon Web Services) is one of the leading cloud computing platforms, offering a wide range of services to individuals, businesses, and governments globally. AWS provides on-demand computing resources and services over the Internet, enabling customers to build and deploy applications, store data, and manage their IT infrastructure with ease and flexibility.
Some key features and services of AWS include:
Compute Services: AWS cloud computing offers a variety of computing services, including Amazon Elastic Compute Cloud (EC2) for virtual servers, AWS Lambda for serverless computing, and Amazon Elastic Container Service (ECS) for containerized applications.
Storage Services: AWS cloud computing provides scalable and secure storage solutions such as Amazon Simple Storage Service (S3) for object storage, Amazon Elastic Block Store (EBS) for block storage, and Amazon Glacier for long-term archival storage.
Database Services: AWS cloud computing offers a range of fully managed database services, including Amazon Relational Database Service (RDS) for relational databases, Amazon DynamoDB for NoSQL databases, and Amazon Redshift for data warehousing.
Networking Services:AWS cloud computing provides networking services such as Amazon Virtual Private Cloud (VPC) for creating isolated virtual networks, AWS Direct Connect for dedicated network connections, and Amazon Route 53 for domain name system (DNS) management.
Security and Identity Services: AWS cloud computing offers a comprehensive set of security services, including AWS Identity and Access Management (IAM) for managing user access and permissions, AWS Key Management Service (KMS) for encryption key management, and AWS Certificate Manager (ACM) for managing SSL/TLS certificates.
Management and Monitoring Tools: AWS cloud computing provides tools such as AWS CloudWatch for monitoring and logging, AWS CloudFormation for infrastructure as code, and AWS Systems Manager for managing and automating operational tasks.
Artificial Intelligence and Machine Learning: AWS cloud computing offers AI and ML services such as Amazon SageMaker for building, training, and deploying machine learning models, Amazon Rekognition for image and video analysis, and Amazon Comprehend for natural language processing.
Internet of Things (IoT): AWS cloud computing IoT provides services for connecting, managing, and securing IoT devices and applications, including AWS IoT Core, AWS IoT Greengrass, and AWS IoT Device Defender.
