AZ-900: MICROSOFT AZURE FUNDAMENTALS |
STUDY GUIDE
Azure - Answers - Microsoft's cloud computing platform
Cloud Computing - Answers - The delivery of computing services over the Internet using
a pay-as-you-go pricing model.
Shared Responsibility Model - Answers - 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 - Answers - 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 - Answers - 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 - Answers - 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 - Answers - users only pay for the resources that they use,
better cost prediction, billing based on usage, etc
Scalability - Answers - the ability to adjust resources to meet demand
Vertical Scaling - Answers - 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 - Answers - 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 - Answers - The ability to do things more efficiently or at a lower-
cost per unit when operating at a larger scale.
, Capital Expenditure - Answers - The decision to spend money on physical infrastructure
up front, and then deducting that expense from your tax bill over time.
Operational Expense - Answers - The decision to spend money on services or products
now and being billed for them now.
High availability - Answers - 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 - Answers - The ability of a resource or system to recover from failures and
continue to function
Predictability - Answers - can be performance or cost-based, performance refers to
resources needed for a positive experience such as autoscaling, load balancing, and
high availability. cost refers to predicting and forecasting the cost and tracking resource
use to adjust in the future
Security - Answers - providing mitigation strategies for update and changes, control
varies with cloud service type
Governance - Answers - compliance with corporate or government standards
Manageability - Answers - managing your cloud resources, automatically scaling
resources, monitoring the health, receiving automatic alerts
Infrastructure as a Service - Answers - Instead of maintaining CPU's, Memory and
Storage in your data center, you rent them for the time that you need them. The cloud
provider takes care of maintaining the underlying infrastructure for you.
Platform as a Service - Answers - A complete development and deployment
environment in the cloud, with resources that enable you to deliver everything from
simple cloud-based apps to sophisticated, cloud-enabled enterprise applications.
Software as a Service - Answers - A complete software solution that you purchase on a
pay-as-you-go basis from a cloud service provider. You rent the use of an app for your
organization, and your users connect to it over the Internet, usually with a web browser.
Azure Region - Answers - One or more Azure data centers within a specific geographic
location. (eg: West US)
Availability Zones - Answers - Availability Zones are unique physical locations within an
Azure region. Each zone is made up of one or more data centers equipped with
independent power, cooling, and networking.
