About this Session
👍A “Beginner session" and strictly not for Cloud experts
👍It won’t teach you everything, But it will help you learn what you need to know to get started
- Basics of Cloud Computing and Cloud Native
- Overview of Azure with Core services
- Demo
THE CHALLENGE
If you ask "What will I learn Today?"
How to turn an idea into production application quickly using cloud
Story time!
So now we could rent hardware
Once upon a time!
But then internet arrived ... and virtualization
What the heck is "Cloud"
Before Cloud
The Cloud
Benefits of Cloud Computing
Funding Models
- Capital Expenditures ( CapEx)
- Operating Expenditures (OpEx)
Types of Cloud
Provider provides resources for various different users.
PUBLIC
PRIVATE
HYBRID
Public Cloud + Private Cloud
Private: processes critical activities
Public: supports non-critical activities, accommodates demand peaks
Serve a single company AND
Provider delivers services to internal users from company data centers
Service Models
Think Of Pizza as a Service
Where to get Cloud?
1 Free year
200$ Credits, 30+ services
300$ Credits, 20+ services
Great place for devs/Cheap cost
What is Cloud Native
[ Cloud Friendly / Cloud Optimised ]
A cloud-native application is an application that has been designed to run on a Platform-as-a-Service and to embrace elastic scaling.
How to Design Cloud Native Apps?
- We need to understand distributed systems.
- We need to understand new technologies such as containers and functions.
- We need to understand what patterns to use when building cloud-native applications.
Key Components of Cloud Native (Remember the word CSK)
Containers
Serverless
Kubernetes
Top 3 lies by developer
It works on my machine
We have not changed anything
You're testing it wrong
The Problem
The solution
What is Container?
- A fully self-contained “thing”
- Application source code
- All runtime dependencies, config files, and binaries
MAKES LIFE WITH CONTAINERS EASIER
Container Orchestration
Kubernetes
Cuban Yeti(s)
- Kubernetes is a portable, extensible open-source platform for managing containerized workloads and services
- Environment to run applications on containers (Docker, but other engines are supported)
microservices
event-driven
Easy Development
and Deployment
zero-administration
pay-per-execution
Serverless
Though servers exist, the developer does not have to think about them.
Let's dive into Azure
The Azure menu of services can be overwhelming.
So many services that it would be difficult to get through them all in this session!
Global Infrastructure
64 Azure Regions
More than AWS & Google Combined
Regions
Core Azure Services
Let me navigate to the Whiteboard
Tips for Beginners
- Implement Spending Caps/Keep an eye on your bill
- Delete everything you don't need
- Least Privilege!! Take care to fully understand permissions and access
- Watch videos, follow tutorials, reach out!
- Have fun
- This stuff is really easy if you know what you are doing
Demo Time

Sentiment Analysis
Idea: "Analyse How world is reacting to WFH"
