Questions With Complete Solutions
Azure - CORRECT ANSWER✔✔-Microsoft's cloud computing platform
| | | | | |
Cloud Computing - CORRECT ANSWER✔✔-The delivery of computing
| | | | | | | |
services over the Internet using a pay-as-you-go pricing model.
| | | | | | | |
Shared Responsibility Model - CORRECT ANSWER✔✔-responsibilities
| | | | | |
shared between the cloud provider and the consumer, varies based on
| | | | | | | | | | |
which cloud service. Consumers are always responsible for information,
| | | | | | | | |
data, accounts, etc. Cloud providers are always responsible for physical
| | | | | | | | | |
hosts, network, and data centers. Infrastructure, applications,
| | | | | | |
networking, and operating system responsibilities vary from model to
| | | | | | | | |
model.
Public Cloud - CORRECT ANSWER✔✔-When have no local hardware to
| | | | | | | | | |
manage or keep up-to-date - everything runs on your cloud provider's
| | | | | | | | | | |
hardware. In some cases, you can save additional costs by sharing
| | | | | | | | | | |
computing resources with other cloud users.
| | | | |
Private Cloud - CORRECT ANSWER✔✔-A cloud environment in your own
| | | | | | | | |
datacenter and provides self-service access to compute resources to
| | | | | | | | | |
,users in your organization. This offers a simulation of a public cloud to
| | | | | | | | | | | | |
your users, but you remain completely responsible for the purchase and
| | | | | | | | | |
maintenance of the hardware and software services you provide
| | | | | | | | |
Hybrid Cloud - CORRECT ANSWER✔✔-The combination of both public
| | | | | | | | |
and private clouds, allowing you to run your applications in the most
| | | | | | | | | | | |
appropriate location. For example, you could host a website in the
| | | | | | | | | | |
public cloud and link it to a highly secure database hosted in your
| | | | | | | | | | | | |
private cloud. |
Consumption based model - CORRECT ANSWER✔✔-users only pay for
| | | | | | | | |
the resources that they use, better cost prediction, billing based on
| | | | | | | | | | |
usage, etc |
Scalability - CORRECT ANSWER✔✔-the ability to adjust resources to
| | | | | | | | |
meet demand |
Vertical Scaling - CORRECT ANSWER✔✔-Known as "scaling up", is the
| | | | | | | | | |
process of adding resources to increase the power of an existing server.
| | | | | | | | | | | |
Some examples of vertical scaling are: adding more CPUs, or adding
| | | | | | | | | | |
more memory. |
Horizontal Scaling - CORRECT ANSWER✔✔-Known as "scaling out", is
| | | | | | | | |
the process of adding more servers that function together as one unit.
| | | | | | | | | | | |
, For example, you have more than one server processing incoming
| | | | | | | | | |
requests.
Economies of Scale - CORRECT ANSWER✔✔-The ability to do things
| | | | | | | | | |
more efficiently or at a lower-cost per unit when operating at a larger
| | | | | | | | | | | | |
scale.
Capital Expenditure - CORRECT ANSWER✔✔-The decision to spend
| | | | | | | |
money on physical infrastructure up front, and then deducting that
| | | | | | | | | |
expense from your tax bill over time.
| | | | | |
Operational Expense - CORRECT ANSWER✔✔-The decision to spend
| | | | | | | |
money on services or products now and being billed for them now.
| | | | | | | | | | |
High availability - CORRECT ANSWER✔✔-Refers to the time that a
| | | | | | | | | |
system is functional and working. Maximizing availability requires
| | | | | | | |
implementing measures to prevent possible service failures. Resources
| | | | | | | |
have service level agreements with performance targets
| | | | | |
Reliability - CORRECT ANSWER✔✔-The ability of a resource or system to
| | | | | | | | | |
recover from failures and continue to function
| | | | | | |
Predictability - CORRECT ANSWER✔✔-can be performance or cost-
| | | | | | |
based, performance refers to resources needed for a positive
| | | | | | | | |
