Microsoft 365 Fundamentals: Cloud Concepts

Flashcards reviewing cloud computing concepts, benefits, and service types.

Cloud Computing

The delivery of computing services over the Internet, including virtual machines, storage, databases, and networking.

Private Cloud

A cloud delivering services over the internet, used by a single entity, providing greater control but potentially higher costs.

Public Cloud

Cloud built, controlled, and maintained by a third-party provider, accessible to anyone wanting to purchase cloud services.

Hybrid Cloud

A computing environment using both public and private clouds in an interconnected manner, allowing for flexible resource deployment.

Multi Cloud

A cloud setup where multiple public cloud providers are used, potentially leveraging different features from each.

Capital Expenditure (CapEx)

Upfront expenses to purchase tangible resources

Operational Expenditure (OpEx)

Spending money on services or products over time

Consumption Based Model

A pricing model where you only pay for the IT resources you use.

Uptime (Availability)

The percentage of time a cloud service is operational and accessible to users.

Scale (Scalability)

The ability of a cloud service to handle increasing or decreasing demand for resources without compromising quality.

Types of Scalability

Vertically (up or down)

Horizontally (in or out)

Automatic

Vertical Scaling

Adding or removing power to an existing cloud server by upgrading or downgrading its memory, storage, or processing power.

Horizontal Scaling

Adding or removing servers or machines to a cloud system by linking them together.

Automated Scaling (Auto Scaling)

Adjusting the resources of a cloud service automatically based on predefined rules and policies.

High Availability

Cloud service is designed to always be accessible and operational, that’s regardless of any failures, outages, disasters that might occur.

Elasticity

Cloud services can automatically and seamlessly adjust their resources according to current demand workload.

Cloud benefits

High availability

Scalability

Elasticity

Reliability

Predictability

Security

Governance

Manageability

What are the cloud surface types

Infrastructure as a service

Platform as a service

Software as a service

Infrastructure as a Service (IaaS)

The most flexible cloud service. You can figure and manage the hardware for your application. Renting servers, virtual machines, storage networks, and operating systems from a cloud provider on a pay-as-you-go basis.

IaaS responsibility

Information and data

Device devices (mobile, and PC)

Accounts and identities

Identity and directory infrastructure

Application

Network controls

Operating system

Platform as a Service (PaaS)

Focus on application development. Platform management is handled by the club provider.

Provides an environment for building, testing, and deploying software applications without managing the underlying infrastructure.

PaaS responsibility

Information and data

Device devices (mobile, and PCs)

Accounts and identities

Can include

Identity and directory infrastructure

Application

Network controls

Software as a Service (SaaS)

Pay as you go pricing model. Users pay for the software they use on a subscription model.

Provides users with access to software applications over the Internet, without the need to install, update, or maintain the software.

SaaS responsibility

Information and data

Device (mobile and PCs)

Accounts and identities

Can include identity and Directory infrastructure

Shared Responsibility Model

Defines the roles and responsibilities of both the cloud provider and the customer in securing and managing the cloud environment.

responsibility always retained by Customer

Information and data

Device (mobile, and PCs)

Accounts and identities

Responsibility transfers to club provider

Physical host

Physical Network

Physical data center

Responsibility varies by type

Identity and directory infrastructure

Application

Network controls

Operating system

What are the types of Microsoft 365

Home

Business

Enterprise

Frontline workers

Are employees whose primary function is to work directly with customers or the general public providing services, support, and selling products, or employees directly involved in the manufacturing and distribution of products or services.
