This document discusses cloud computing technologies. It begins by defining cloud computing as using computing resources like processing power, storage, applications, and servers on-demand through the internet. Examples given include accessing email from anywhere and collaborating on documents online in real-time. The document then lists some business benefits of cloud computing like reducing costs, easy scaling, collaboration, and security handled by cloud providers. It also covers different types of cloud models including public, private, hybrid and community clouds. The document concludes by mentioning challenges of cloud computing like security vulnerabilities but also quotes experts who argue cloud can be more secure than traditional computing.

“I don't need a hard disk in my computer if I
can get to the server faster... carrying around
these non-connected computers is byzantine
by comparison.”

5. Introduction
• Use of computing resources like processing power,
storage, applications, servers etc. from anywhere
on-demand through internet is cloud computing.
• Examples:
• Checking email from anywhere around the
world like Gmail, Protonmail
• Collaborating to edit documents online on
real-time and saving on cloud
• and many more…

6. • Business? … cloud reduces capital expenses
• software/security updates, maintenance, configuration?? ugh.. no need to
worry
• Seasonal business? scale-up or scale-down as per the need
• Collaboration is easy
• Access from anywhere using any device …
• Security?? cloud service providers’ business
• Buy just the service that is needed, nothing else.. No extra hardware/
softwares

7. Types of cloud
Based on location — Public, private, hybrid and community cloud
• Public: Cloud computing company’s infrastructure, located on their
own premises; public customers pay and get services.
• Private: Infrastructure solely owned by one customer/organization, not
shared with others. Security and control is highest in private clouds.
• Hybrid: using both — public cloud to interact with customers, private
to store data
• Community cloud: Shared between organizations — for example
cloud owned by government

9. Cloud computing in 2018
•Multi-cloud goes mainstream
•Not only cloud adoption but optimization
•Containers, micro-services are hot topics
•Serverless — Back-end as a Service (BaaS) in practice
•Cloud Monitoring as a Service (CMaaS) to monitor
performance across multiple cloud service providers

11. … and what are the challenges?
• Victim of web application attacks
• Misconfigurations leads to app and data exposed
• Cryptomining in cloud platforms
• Security?? always a challenge

“The cloud services companies of all sizes…
The cloud is for everyone. The cloud is a
democracy.”

“Cloud computing is often far more secure than
traditional computing, because companies like
Google and Amazon can attract and retain
cyber-security personnel of a higher quality
than many governmental agencies.”
