What exactly is the cloud?

The cloud refers to software and services that run on the Internet, instead
of locally on your computer.
"The cloud" refers to servers that are accessed over the Internet, and the
software and databases that run on those servers.

What is Cloud
Computing?
Cloud computing is the
on-demand availability of
computer system
resources, especially data
storage and computing
power, without direct
active management by
the user.
 The cloud helps you move faster and innovate in ways that were once nearly
impossible.
In our ever-changing digital world, two trends emerge:
• Teams deliver new features to their users at record speeds.
• Users expect an increasingly rich and immersive experience with their devices and with
software.

Software releases were once scheduled in terms of months or even years.

• Today, teams release features in smaller batches that are often scheduled in days or
weeks.
• Some teams even deliver software updates continuously--sometimes with multiple
releases within the same day.
To power your services and deliver innovative and novel user experiences more quickly,
the cloud provides on-demand access to:

1. A nearly limitless pool of raw compute, storage, and networking components.

2. Speech recognition and other cognitive services that help make your application stand
out from the crowd.
3. Analytics services that deliver telemetry data from your software and devices.
Capital expenditures (CapEx) refers to long-term business
investments expected to be utilized for multiple years. It’s expected
that CapEx will continue to benefit the business in the future and
eventually pay for itself.
Maintenance increases the life and utility of a CapEx item is
therefore also a capital expenditure. Examples of CapEx items
include printers, land, and generators.
Operating expenditures (OpEx) are incurred in the day-to-day
operation of a business, and generally include services or items
expected to be used within a year. This also includes subscriptions,
such as SaaS, or other services billed on a flexible or scheduled
cadence. While operating expenditures are no less important than
capital expenditures, they are not considered long-term
investments.

other devices or clients
PING (Latency) means the time it takes for a small data set to be transmitted from your device to a server on the Internet and back to
your device again.

Cloud Computing Services
Software As A Service (SaaS)

Software as a service is used for

web-based applications. SaaS is a
method for delivering software
applications over the Internet where
cloud providers host and manage the
software applications making it
easier to have the same application
on all of your devices at once by
accessing it in the cloud.
Platform As A Service (PaaS)

PaaS removes the need for

organizations to manage the
underlying infrastructure (usually
hardware and operating systems)
and allow you to focus on the
deployment and management of
your applications.
This helps you be more efficient as
you don’t need to worry about
resource procurement, capacity
planning, software maintenance,
patching, or any of the other
undifferentiated heavy lifting
involved in running your application.
Infrastructure As A Service (IaaS)

Infrastructure as a Service, sometimes

abbreviated as IaaS, contains the basic
building blocks for cloud IT and typically
provide access to networking features,
computers (virtual or on dedicated
hardware), and data storage space.
Infrastructure as a Service provides you
with the highest level of flexibility and
management control over your IT
resources and is most similar to existing IT
resources that many IT departments and
developers are familiar with today.
Serverless computing
What is serverless computing?

• The serverless application allows us to focus on your application logic without worrying about any
servers, A third-party service host application. It is also known as FaaS (function as a service).
• There are no servers to maintain, software to manage, and no hardware to upgrade — the software
built-in with high availability and fault tolerance.
• Serverless computing helps teams increase their productivity and bring products to market faster, and it
allows organizations to better optimize resources and stay focused on innovation.

▪ A public IP address identifies you to the wider internet so that all the information you’re
searching for can find you.
▪ A private IP address is used within a private network to connect securely to other devices
within that same network.

Each device within the same network has a unique private

IP address.
 Public and Private IP address
▪ There are millions of private networks across the globe, all of which include devices assigned
private IP addresses within these ranges:

▪ Class A: 10.0.0.0 — 10.255.255.255

▪ Class B: 172.16.0.0 — 172.31.255.255

▪ Class C: 192.168.0.0 — 192.168.255.255

These IP addresses can be reused on different private networks all over the world — without
consequence or confusion.
192.168 series is the most common default private IP address
format assigned to network routers around the globe.

What can I Do With Azure?

• Azure provides more than 100 services that enable you to do everything from running your
existing applications on virtual machines, to exploring new software paradigms, such as
intelligent bots and mixed reality.

• Many teams start exploring the cloud by moving their existing applications to virtual machines
that run in Azure. Migrating your existing apps to virtual machines is a good start, but the cloud
is much more than a different place to run your virtual machines.

• For example, Azure provides AI and machine-learning services that can naturally
communicate with your users through vision, hearing, and speech. It also provides storage
solutions that dynamically grow to accommodate massive amounts of data. Azure services
enable solutions that aren't feasible without the power of the cloud.

• Azure Batch - Managed service for parallel and high-performance computing applications.

• Azure Container Instances - Containerized apps run on Azure without provisioning servers or VMs.

• Azure Functions - An event-driven, serverless compute service.

Azure Virtual Machines
• Virtual machines are software emulations of physical computers.
They include a virtual processor, memory, storage, and
networking resources. VMs host an operating system, and you can
install and run software just like a physical computer. When using
a remote desktop client, you can use and control the VM as if you
were sitting in front of it.

• With Azure Virtual Machines, you can create and use VMs in the
cloud. Virtual Machines provides infrastructure as a service (IaaS)
and can be used in different ways. When you need total control
over an operating system and environment, VMs are an ideal
choice. Just like a physical computer, you can customize all the
software running on the VM. This ability is helpful when you're

Secure Shell (SSH)

• SSH or Secure Shell is a network communication protocol that enables two

computers to communicate (c.f http or hypertext transfer protocol, which is the
protocol used to transfer hypertext such as web pages) and share data.

• SSH provides password or public-key based authentication and encrypts connections

between two network endpoints. ... In addition to providing strong encryption, SSH is
widely used by network administrators to manage systems and applications remotely,
deliver software patches, or execute commands and move files.
• An SSH server, by default, listens on the standard Transmission Control Protocol (TCP)
port 22.
How does SSH work?

• The SSH protocol is based on the client-server model. Therefore, an SSH

client must initiate a SSH session with a SSH server.
• The server responds by sending the client a public cryptography key. The
server negotiates parameters and opens a secure channel for the client.
• SHH offers encryption for data transfer that restricts hackers and attackers
from hacking your server password and user information.
• Another benefit of using SSH is that it allows you to tunnel other network
protocols.
