High Availability

High Availability: Services are very rarely down. 3-5 "nines". 99.999% available

Knowledge Center

○ Large question and answer database for Azure help

Consumption-based model

○ OpEx, pay for what you use, etc ○ No up-front costs

Disaster Recovery

A complete plan to recover critical business systems and normal operations in the event of a catastrophic disaster or cyber attack. Region-pairs are a good building block here

Agility

Agility for many organizations means reacting swiftly to a changing environment. This is jumping from one task to the next, change requirements, being able to change scope and adapt to an ever moving target. When it comes to the cloud context, agility is all about the ability of an organization to rapidly develop, test, and launch software applications that drive business growth. Cloud agility ensures that businesses are empowered to priorities issues.

Security Center

Analyzes the security state of your Azure resources. When Security Center identifies potential security vulnerabilities, it creates recommendations based on the controls set in the security policy. The recommendations guide you through the process of configuring the needed security controls. For example, if you have workloads that do not require the Azure SQL Database Transparent Data Encryption (TDE) policy, turn off the policy at the subscription level and enable it only in the resources groups where SQL TDE is required

Elasticity

Automatically adding or removing resources due to spikes or drops in demand

Security Policy

Defines the set of controls that are recommended for resources within that specified subscription or resource group. In Security Center, you define policies according to your company's security requirements

Fault Tolerance

Having a backup plan that self-fixes if something goes wrong. I.e. moving a workload to a different Availability Zone

What are the benefits and usage of core Azure architectural components

Such a vague question lol wat

Economies of scale

The ability to do things more efficiently or at a lower-cost per unit when operating at a larger scale. See: Sam's (buying a ton of stuff is cheaper). This is what cloud providers do with servers, they buy a ton, so they get deals and we rent those servers from them at lower prices than we could buy

Scalability

The ability to increase or decrease the resources and services used based on demand or workload at any given time. Vertical and horizontal scaling (improving servers and adding servers)

Compare and contrast the three different cloud models

The one you choose depends on your budget, and on your security, scalability, and maintenance needs
