Unit-1 Introduction to Cloud Computing

What is cloud computing?

• Cloud computing is the delivery of computing services over the internet.

• Cloud computing is only for large enterprises.

• Cloud computing refers to local server storage.

• Cloud computing is a type of hardware.

Name the different types of cloud computing.

• DaaS

• IaaS, PaaS, SaaS, Public Cloud, Private Cloud, Hybrid Cloud, Community Cloud

• Cloud Storage Service

• Virtual Cloud

List three characteristics of cloud computing.

• High latency access

• 1. On-demand self-service 2. Broad network access 3. Resource pooling

• Manual resource allocation

• Limited storage capacity

What are the benefits of using cloud systems?

• Reduced security measures

• Scalability, cost efficiency, accessibility, and enhanced collaboration.

• Limited data storage

• Increased hardware requirements

What are some disadvantages of cloud computing?

• Increased storage capacity

• Enhanced data security

• Improved performance and speed

• Security risks, potential downtime, limited control, and reliance on internet connectivity.

How do you assess the value proposition of cloud services?

• Reduced collaboration capabilities

• Increased hardware costs

• Cost efficiency, scalability, flexibility, enhanced security, and improved performance.

• Limited access to data

What metrics can be used to measure the cloud's value?

• User interface design

• Network latency

• Cost savings, performance improvements, scalability, uptime, security, user satisfaction, ROI.

• Data storage capacity

Define capital expenditures in the context of cloud computing.

• The upfront costs for acquiring and deploying cloud infrastructure and services.

• Expenses related to employee training for cloud services

• Costs associated with software licensing

• Recurring costs for cloud service subscriptions

What is total cost of ownership (TCO) in cloud systems?

• TCO only includes initial setup costs.

• TCO is the price of cloud services per month.

• TCO refers to the performance metrics of cloud systems.

• The total assessment of all costs associated with cloud services over their lifecycle.

What are service level agreements (SLAs) in cloud computing?

• Contracts that define the expected service levels, including performance, availability, and responsibilities.

• SLAs are only related to data storage costs.

• SLAs are informal agreements without legal binding.

• SLAs guarantee 100% uptime without exceptions.
