Examples of computing resources include networks, servers, storage, applications, and services. Dr. JOHN ZAKI 10 INTRODUCTION CLOUD HAS 5 ESSENTIAL CHARACTERISTICS On demand self-service, broad network access, resource, pooling, rapid elasticity, measured service. 4 DEPLOYMENT MODELS Public, Private, Hybrid, and Community Cloud 3 SERVICE MODELS IaaS, PaaS, SaaS Dr. JOHN ZAKI 11 5 CHARACTERISTICS: ON-DEMAND SELF-SERVICE 1. Access the cloud resources everyday all day except for an outage or a security breach, the service is available without exception. 2. It is like an ATM.. That is available at all times except when it is broken or is being fed by the service provider. Dr. JOHN ZAKI 12 5 CHARACTERISTICS: BROAD NETWORK ACCESS 1. CLOUD COMPUTING RESOURCES 2. PUBLIC CLOUD SERVICES 3. MULTITUDE OF DEVICES 4. INTERNET ACCESS FOR PUBLIC CLOUD SERVICES 5. INTERNET ON PRIVATE CLOUD Dr. JOHN ZAKI 13 5 CHARACTERISTICS: RESOURCE POOLING 1. SAVES ON COST 2. COMPUTING RESOURCES SERVE MULTIPLE CUSTOMERS 3. CLOUR RESOURCES ARE DYNAMICALLY ASSIGNED AND REASSIGNED 4. REGARDLESS OF THE PHYSICAL LOCATION Dr. JOHN ZAKI 14 5 CHARACTERISTICS: RAPID ELASTICITY 1. INCREASE AND DECREASE RESOURCES AS PER DEMAND 2. VERTICAL SCALING OR HORIZONTAL SCALING 3. ADD OR DECREASE RESOURCES AS PER THE NUMBER OF USERS.
