1. What are 4 of the basic services that Cloud Providers povide?: CANS
Compute power - such as Linux servers or web applications
Analytics - such as visualizing telemetry and performance data
Networking - such as secure connections between the cloud provider and your
company
Storage - such as files and databases
2. Advantages/Benefits of the Cloud: High availability: Depending on the ser-
vice-level agreement that you choose, your cloud-based applications can provide a
continuous user experience with no apparent downtime even when things go wrong.
Scalability: Applications in the cloud can be scaled in two ways:
Vertically: Computing capacity can be increased by adding RAM or CPUs to a virtual
machine.
Horizontally: Computing capacity can be increased by adding instances of a re-
source, such as adding more virtual machines to your configuration.
Elasticity: Cloud-based applications can be configured to take advantage of
auto-scaling, so your applications will always have the resources they need.
Agility: Cloud-based resources can be deployed and configured quickly as your
application requirements change.
Geo-distribution: Applications and data can be deployed to regional datacenters
around the globe, so your customers always have the best performance in their
region.
Disaster recovery: By taking advantage of cloud-based backup services, data repli-
cation, and geo-distribution, you can deploy your applications with the confidence
that comes from knowing that your data is safe in the event that disaster should
occur.
3. Benefits of using Azure: Be ready for the future: Continuous innovation from
Microsoft supports your development today and your product visions for tomorrow.
Build on your terms: You have choices. With a commitment to open source, and
support for all languages and frameworks, build how you want and deploy where
you want to.
Operate hybrid seamlessly: On-premises, in the cloud, and at the edge--we'll meet
you where you are. Integrate and manage your environments with tools and services
designed for a hybrid cloud solution.
Trust your cloud: Get security from the ground up, backed by a team of experts, and
proactive compliance trusted by enterprises, governments, and startups.
4. What are typical Compute power choices?: VACS
Virtual Machines: Software emulations of physical computers
Azure App Service: a platform-as-a-service (PaaS) offering in Azure that is designed
to host enterprise-grade web-oriented applications

Containers provide a consistent, isolated execution environment for applications.
They're similar to VMs except they don't require a guest operating system. Instead,
the application and all its dependencies is packaged into a "container" and then a
standard runtime environment is used to execute the app. This allows the container
to start up in just a few seconds, because there's no OS to boot and initialize. You
only need the app to launch.
Serverless Computing lets you run application code without creating, configuring, or
maintaining a server. The core idea is that your application is broken into separate
functions that run when triggered by some action. This is ideal for automated tasks
- for example, you can build a serverless process that automatically sends an email
confirmation after a customer makes an online purchase.
5. Main difference between VMs and Containers: Containers don't need a host
OS and are smaller and thus more resource-efficient than VMs
6. What's the main benefit of Serverless Computing compared to VMs or
Containers?: The serverless model differs from VMs and containers in that you only
pay for the processing time used by each function as it executes. VMs and containers
are charged while they're running - even if the applications on them are idle.
7. What are the four major subjects to know for the fundamentals exam?: -
CASC
* Cloud Concepts
* Azure Pricing and Support
* Security, Privacy, Compliance and Trust
* Core Azure Services
8. Can you have several subscriptions at the same time?: Yup
9. Does it make sense to have multiple subscriptions?: Yes. Some companies
do this for billing purposes; they get separate billing and invoicing reports. Or for
separating Production from development subscriptions.
10. Who owns the azure subscription?: The person that creates the subcription
11. What are the purchasing options for Azure products and services?: WEC
Web Direct
Enterprise
Cloud Solution Provider
12. Enterprise Agreement: agreement to purchase a pre-determined amount of
Azure Services.
Savings of 15-45% percent with respect to Web Direct users
13. When do you qualify for an Enterprise agreement?: As a private business
you have to have 500 users and devices. As a public organization you must have at
least 250 users and devices

14. When do you qualify to become a CSP?: you need to sign an agreement with
Microsoft.
15. What is a Region?: A region is a geographical area on the planet containing
at least one, but potentially multiple datacenters that are nearby and networked
together with a low-latency network. Azure intelligently assigns and controls the
resources within each region to ensure workloads are appropriately balanced.
16. What is a geography and why do they matter?: An Azure geography is a dis-
crete market typically containing two or more regions that preserve data residency
and compliance boundaries.
They matter because:
1. Geographies allow customers with specific data residency and compliance needs
to keep their data and applications close.
2. Geographies ensure that data residency, sovereignty, compliance, and resiliency
requirements are honored within geographical boundaries.
3. Geographies are fault-tolerant to withstand complete region failure through their
connection to dedicated high-capacity networking infrastructure.
17. Which are the current Geographies?: Americas
Europe
Asia Pacific
Middle East and Africa
18. What is an availability zone?: Availability Zones are physically separate data-
centers within an Azure region.
Each Availability Zone is made up of one or more datacenters equipped with inde-
pendent power, cooling, and networking. It is set up to be an isolation boundary. If
one zone goes down, the other continues working. Availability Zones are connected
through high-speed, private fiber-optic networks.
19. Azure services that support Availability Zones fall into which categories: -
two categories:
Zonal services - you pin the resource to a specific zone (for example, virtual
machines, managed disks, IP addresses)
Zone-redundant services - platform replicates automatically across zones (for ex-
ample, zone-redundant storage, SQL Database).
20. What are region pairs and why are they important?: Each Azure region
is always paired with another region within the same geography (such as US,
Europe, or Asia) at least 300 miles away. This approach allows for the replication of
resources (such as virtual machine storage) across a geography that helps reduce
the likelihood of interruptions due to events such as natural disasters, civil unrest,
power outages, or physical network outages affecting both regions at once.

21. Does every region have two or more Availability Zones?: Nope. SomeEven
have none...
Not every region has support for Availability Zones. The following regions have a
minimum of three separate zones to ensure resiliency.
Central US
East US 2
West US 2
West Europe
France Central
North Europe
Southeast Asia
22. Do usage costs vary between regions?: Yup, slightly.
23. How do you choose the region you need to deploy: normally you choose the
region closest to your users, but you also have to weigh in the cost you'll incur in
that region.
24. How can you estimate costs? And how can you come to the best estimate?-
: Using the Price Calculator. To get the best estimate you need to know exactly what
you'll deploy and where.
25. Are there several pricing options for VMs?: Yup,
* Normal
* Reserved VM Instances
* Hybrid Benefit
* DEV/TEST pricing
26. How do I Calculate the total savings i can get by moving to the cloud?: Us-
ing the Total Cost of Ownership Calculator
27. What's the difference -if any- between Spending limits and quotas?: The
spending limit is equal to the amount of credit and it can't be changed. It can be
removed though (if you move to a pay as you go subscription). Quotas relate to
resources (max nr of VMs per account and such)
28. What do you use tags for?: To group resources logically and create an cost
report based on that goup.
29. What are Azure Reservations?: They are paying in advance for specific prod-
ucts for a pre-determined period
30. Ho much cost savings can i make with Azure Reservations?: up to 72% over
pay-as-you-go subscriptions
31. What is Azure Advisor?: It can advise you about different subjects:
* High Availability
* Security
