Cloud Concepts - Is the Cloud right for you? Flashcards
What are some key questions to consider before deciding to move to the cloud?
Where is the business going? What are you trying to achieve? What are your business objectives?
Why is it important to identify your key drivers for improvement and challenges in your organization?
Identifying key drivers for improvement and challenges helps determine areas that could benefit from cloud adoption and additional business functionality.
What is on-demand resourcing in the context of cloud computing?
On-demand resourcing means that resources within the cloud are immediately available for allocation when needed, allowing for quick provisioning.
What are the advantages of on-demand resourcing compared to traditional sourcing of additional resources?
On-demand resourcing in the cloud provides almost instant access to resources without the lengthy process of sourcing, ordering, and waiting for delivery of hardware in traditional on-premise solutions.
What is scalability in cloud computing?
Scalability in cloud computing refers to the ability to rapidly adjust the resources of an environment, such as compute, storage, or network, both up and down, based on the requirements and demands of applications and services.
How does scalability in the cloud differ from scaling in a traditional on-premise environment?
Cloud scalability allows for rapid deployment and adjustment of resources, while traditional on-premise scaling often requires significant time, resources, and infrastructure expansion.
What is the concept of economy of scale in cloud computing?
Economy of scale in cloud computing refers to the cost advantage gained by cloud providers due to their ability to purchase and share resources in large scales, resulting in lower compute, storage, and network costs for end users compared to traditional hosting.
How does the flexibility and elasticity of cloud computing benefit organizations?
Cloud computing offers the flexibility to deploy resources and services as needed, allowing for rapid provisioning and scaling based on demand. This helps organizations avoid underprovisioning or overprovisioning resources and ensures optimal customer experience.
How does utility-based metering work in cloud computing?
Utility-based metering means that users only pay for the resources they use in the cloud. Similar to paying for electricity usage, cloud users are billed based on the actual consumption of resources.
What are the benefits of shared infrastructure in the cloud?
Shared infrastructure in the cloud allows multiple tenants to run instances on the same hardware, reducing the physical hardware, power, cooling, and space requirements in data centers. This results in cost savings for end users.
How does the cloud provide high availability and resiliency compared to on-premise solutions?
The cloud’s underlying infrastructure often replicates core services across different geographic zones and regions, offering built-in offsite replication and resiliency. This provides greater availability and durability for data without the need for extensive on-premise business continuity solutions.
What are the security advantages of using public cloud vendors?
Public cloud vendors, such as AWS and Microsoft Azure, are considered more secure than on-premise data centers. They adhere to global governance and compliance standards, invest heavily in security infrastructure, and provide the same high level of security to individual users and large corporations.
How is security managed in the cloud, and what is the responsibility of the end user?
Public cloud vendors ensure security for the underlying infrastructure, while end users are responsible for architecting security using available tools, services, and applications. It’s recommended to involve security specialists to implement security measures at all levels of deployments.
What are some benefits that the cloud can bring to a business?
The cloud offers advantages such as on-demand resource allocation, scalability, economy of scale, flexibility, utility-based metering.
