A quick glance at the cloud computing

Definition

The term "cloud" refers to the utilization of a collection of services, applications, information, and infrastructure that is made up of pools of computing, network, information, and storage resources. These components may be swiftly organized, provided, installed and decommissioned, and scaled up or down, enabling an on-demand utility-like allocation and consumption model.

Cloud computing is defined by five essential characteristics, three cloud service models, and four cloud deployment models and cloud management has five major components.

#5 Essential Characteristics

1. Broad Network access

2. Rapid Elasticity

3. Measured Service

4. On-Demand Self -Service

5. Resource Pooling

# 3 Cloud service models

1. Software as a Service (SaaS)

2. Platform as a Service (PaaS)

3. Infrastructure as a Service (IaaS)

#4 Cloud Deployment models

1. Public

2. Private

3. Hybrid

4. Community

#5 Cloud Management Components

1. Automation and Orchestration 

• Application migration
• VM images/instances
• Configuration management

2. Security

• IAM
• Encryption
• Mobile/endpoint security

3. Governance and compliance

• Risk assessments/threat analysis
• Audits
• Service and resource governance

4.  Performance Monitoring

• Storage
• Networks
• Applications
• Compute

5. Cost Management

• Cloud instance right sizing
• User charge back and billing

Savings in the IT Industry - Global Energy-Conservation

Cost reduction is one of the most important actions that all IT firms are adopting. One of these is the decrease in infrastructure costs. A large number of apps were housed on physical servers, incurring data-centre utility costs. By shifting to a cloud environment, IT organizations are effectively cutting data centre utilization costs.

This in turn significantly reduces global energy savings. And it's a step in the right direction for the environment.

The amount of electrical energy used to keep the data centre running is lowered. A significant amount of physical server manufacturing energy has been saved, which have a direct correlation to CO2 emissions. Finally, cloud computing is a green way to save the environment.

Thank you!
