Q3-4 Why Is the Cloud the Future for Most Organizations? Flashcards
What is meant by “on-premise” computing infrastructure?
“On-premise” refers to the practice of organizations constructing and maintaining their own computing infrastructure on their premises, where they purchase or lease hardware to support applications like email, websites, and in-house systems.
What is the cloud?
The cloud is the elastic leasing of pooled computer resources over the Internet. It allows organizations to dynamically scale computing resources based on their needs, using shared hardware through cloud vendors like Amazon and Microsoft.
What does “elastic” mean in the context of cloud computing?
“Elastic” means that the amount of resources leased can be increased or decreased dynamically and programmatically, allowing organizations to pay only for the resources they use, adjusting as demand changes.
What does “pooled” mean in cloud computing?
“Pooled” refers to cloud vendors sharing the same physical hardware across many organizations, dynamically allocating tasks based on customer needs.
This shared model allows for efficient use of resources.
What are the benefits of economies of scale in cloud computing?
Economies of scale mean that as the size of the cloud operation increases, the average cost of production decreases.
Cloud vendors can pass on savings to users, reducing the cost of computing for everyone using the cloud.
How do Internet protocols and standards support cloud computing?
Internet protocols and standards, such as additions to TCP/IP, allow cloud vendors to provide processing capabilities flexibly and in a standardized way, making it easier for different companies to share resources without complex coordination.
Who dominates the cloud market, and what is their market share?
Amazon, through Amazon Web Services (AWS), dominates the cloud market, holding more than 30% of the market share.
Microsoft, IBM, and Google together control about 20% of the market.
What are examples of cloud services offered by vendors?
Examples of cloud services include Microsoft Office Online, Google G Suite, Salesforce CRM, AWS (variety of services), Box (file storage), and Concur (expense management).
What is the expected trend in cloud market growth?
The cloud market grew by 25% in 2016 and was expected to continue at that rate through 2021.
By 2021, 85% of all data center traffic is expected to be in the cloud.
What are some advantages of cloud-based hosting over in-house hosting?
Cloud-based hosting offers advantages such as small capital requirements, known cost structure, responsiveness to demand fluctuations, strong security and disaster response, no obsolescence, lower costs due to economies of scale, and less need for IT staff and personnel.
What is the primary advantage of in-house hosting over cloud hosting?
The primary advantage of in-house hosting is control of data.
You know where your data is stored, how many copies exist, and have more flexibility in managing your data without reliance on external vendors.
Why is the cost structure of cloud-based hosting advantageous?
Cloud-based hosting provides a known cost structure, allowing businesses to scale resources as needed and avoiding surprises in costs related to customer demand fluctuations.
How does cloud hosting handle security and disaster recovery?
Cloud vendors often provide best-in-class security and disaster recovery solutions, allowing businesses to benefit from economies of scale without having to manage these services in-house.
What is a key personnel advantage of cloud-based hosting?
Cloud-based hosting reduces the need to train and manage IT personnel, as much of the infrastructure is handled by the cloud provider.
What flexibility does in-house hosting provide?
In-house hosting offers flexibility in controlling how data is collected, stored, and processed, without being subject to vendor management, policies, or price changes.
