Cloud computing

The document discusses cloud computing, which involves utilizing computing resources delivered over the internet, highlighting its five characteristics, three service models (SaaS, PaaS, IaaS), and four deployment models (private, community, public, hybrid). It emphasizes the advantages such as cost savings, improved performance, and universal access, alongside disadvantages like the need for constant internet connectivity and potential security issues. Overall, cloud computing offers scalable and efficient resource management, transforming how individuals and organizations handle data and applications.

INTRODUCTION Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over the Internet.
When you store your photos online instead of on your home computer, or use webmail or a social networking site, you are using a “cloud computing” service.
 Cloud Computing promotes availability and is composed of  Five essential characteristics  Three service models and  Four deployment models
CHARACTERISTICS There are five key characteristics of cloud computing:  On-demand self service  Broad network access  Resource pooling  Rapid elasticity and  Measured service
SERVICE MODELS Service Models are the reference models on which the Cloud Computing is based. These can be categorized into three basic service models:  Software as a Service (SaaS)  Platform as a Service (PaaS) and Infrastructure as a Service (IaaS)
Cloud Clients Web browser, mobile app, clients SaaS Application CRM, Email, games, virtual desktop PaaS Database, web server, deployment tools IaaS Virtual machines, storage, networks Platform Infrastructure
DEPLOYMENT MODELS Deployment models define the type of access to the cloud. These are:  Private cloud  Community cloud  Public cloud and  Hybrid cloud
PURPOSE OF CLOUD COMPUTING By using the Cloud infrastructure on “pay as used and on demand”, all of us can save in capital and operational investment! Clients can: Put their data on the platform instead of on their own desktop PCs and/or on their own servers. They can put their applications on the cloud and use the servers within the cloud to do processing and data manipulations etc.
Lower Computer Cost Improved Performance Universal document access Increased data reliability Reduced software costs Unlimited storage capacity Improved document format compatibility Instant software updates Advantages
DISADVANTAGES OF CLOUD COMPUTING Requires a constant Internet connection Does not work well with low-speed connections Features might be limited Stored data might not be secure
