Worksheet time: 10mins
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.
Explain the different licensing models for cloud services.
Pay-as-you-go, Subscription, Reserved Instances, Free Tier, and Enterprise Licensing.
One-time purchase model
Hardware leasing model
Open-source licensing model
How does scalability relate to cloud computing?
Scalability allows cloud computing resources to be adjusted dynamically based on demand.
Scalability has no impact on performance in cloud environments.
Scalability is only relevant for on-premises servers.
Scalability limits the resources available in cloud computing.
What role does security play in cloud computing?
Security is crucial in cloud computing as it protects data and applications from unauthorized access and cyber threats.
Security is optional in cloud computing and can be ignored.
Security is primarily the responsibility of the end user, not the cloud provider.
Security only affects physical hardware, not cloud services.
Describe the concept of multi-tenancy in cloud environments.
Multi-tenancy means each client has a separate instance of the application.
Multi-tenancy is a method of storing data on local servers only.
Multi-tenancy allows only one client to access the application at a time.
Single instance of a software application serving multiple clients, with data isolation and shared resources.
What is the significance of data redundancy in cloud systems?
Data redundancy decreases data security in cloud systems.
Data redundancy eliminates the need for backups in cloud systems.
Data redundancy improves data availability and reliability in cloud systems.
Data redundancy is only necessary for on-premises systems.
What is the primary advantage of using a hybrid cloud model?
A hybrid cloud model eliminates the need for any on-premises resources.
A hybrid cloud model is only suitable for small businesses.
A hybrid cloud model combines on-premises infrastructure with public cloud services, providing flexibility and scalability.
A hybrid cloud model allows for complete isolation of data.
How does data encryption enhance security in cloud computing?
Data encryption makes data unreadable to unauthorized users, enhancing security in cloud computing.
Data encryption is not necessary in cloud environments.
Data encryption slows down cloud services significantly.
Data encryption only protects data during transmission, not at rest.
What is the role of APIs in cloud computing?
APIs limit the functionality of cloud services.
APIs are only used for data storage.
APIs in cloud computing facilitate communication between different software applications and services.
APIs are irrelevant in cloud environments.
What is the difference between IaaS, PaaS, and SaaS in cloud computing?
All three are the same and provide identical services.
IaaS is only for storage, PaaS is for networking, and SaaS is for hardware.
IaaS requires physical servers, PaaS is only for mobile apps, and SaaS is for desktop applications.
IaaS provides virtualized computing resources over the internet, PaaS offers a platform for developers to build applications, and SaaS delivers software applications over the internet.
How does cloud computing support disaster recovery?
Cloud computing provides backup solutions and data replication across multiple locations, enhancing disaster recovery capabilities.
Cloud computing requires manual intervention for disaster recovery.
Disaster recovery in cloud computing is only possible with on-premises solutions.
Cloud computing does not support disaster recovery.
