 WHAT IS CLOUD COMPUTING?


Cloud computing refers to the use of hosted services, such as data storage, servers, databases, networking, and software, over the Internet. The data is stored on physical servers maintained by a cloud service provider. Computer system resources, especially data storage and computing power, are available on-demand without direct management by the user in cloud computing.


CLOUD COMPUTING ARCHITECTURE 


Instead of saving files on a physical storage device or hard drive, users can save them on the cloud, allowing access to files from anywhere with internet access. Cloud services are categorized into Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS). Additionally, based on deployment models, clouds can be classified as public, private, or hybrid. Cloud technology comprises two main layers: the front-end layer, which users interact with to access their data via cloud computing software, and the back-end layer, consisting of hardware and software like computers, servers, and databases that securely store data. Middleware, a type of software, acts as a bridge between these layers, ensuring smooth interaction and data exchange.

 TYPES OF CLOUD COMPUTING Cloud computing can either be classified based on the deployment model or the type of service. Based on the specific deployment model, we can classify clouds as public, private, and hybrid clouds. At the same time, it can be classified as infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and software-as-a-service (SaaS) based on the service the cloud model offers. Types Of Cloud Computing  PRIVATE CLOUD A private cloud offers computing services over a private IT network for a single organization's use, also known as internal, enterprise, or corporate cloud. It is managed internally and is not accessible to outsiders. A private cloud provides the benefits of a public cloud, such as self-service, scalability, and flexibility, with added control, security, and customization. It ensures higher security through company firewalls and internal hosting, keeping sensitive data safe from third parties. However, the organization must handle all m...

POSTER OF SMARTWATCH

A smartwatch is a wearable device that combines the features of a traditional watch with advanced technology similar to a smartphone. It tracks health metrics like heart rate, steps, sleep, and blood oxygen levels. Smartwatches deliver notifications for calls, messages, and apps, and often allow music control and voice commands. They come with GPS for tracking outdoor activities and customizable watch faces and bands. Advanced features include contactless payments, smart home control, and emergency alerts. Popular models include the Apple Watch, Samsung Galaxy Watch, Fitbit Versa, and Garmin Forerunner. Future improvements may include better AI for health insights, longer battery life, and new health tracking metrics. Overall, smartwatches help users stay connected, healthy, and organized.
