This presentation covers different cloud architectures including traditional on-premise, Infrastructure as a Service (IaaS), hybrid cloud, multi-cloud, and how to choose the right one. On-premise offers control but is expensive and less flexible, while IaaS allows renting infrastructure resources. Hybrid cloud uses a mix of on-premise and public/private clouds for flexibility and cost savings but is complex. Multi-cloud spreads use across multiple providers for flexibility and avoiding vendor lock-in. Choosing an architecture depends on factors like objectives, security, costs, and expertise. Cloud architectures provide businesses with needed agility, scalability and cost savings for today's digital economy.

● Brief overview of what will be covered in the presentation
Presentation by: Sanjay Paudel

2. Traditional On-Premise
Architecture
● Definition and explanation of traditional on-premise IT infrastructure:
On-premise IT infrastructure refers to an IT environment where all the
hardware, software, and data are stored and managed within the
business premises.
● Advantages and disadvantages of on-premise architecture: On-
premise architecture offers better security and control, but it's
expensive and less flexible.

3. Cloud Architectures
● Infrastructure as a Service (IaaS): IaaS is a cloud computing model
where businesses rent IT infrastructure, such as servers, storage, and
networking, from a cloud provider.

4. Hybrid Cloud Architecture
● Definition and explanation of Hybrid Cloud Architecture: Hybrid cloud
architecture is a mix of on-premise and cloud infrastructure, where
businesses use a combination of public and private cloud services to
deploy their IT services and applications.
● Advantages and disadvantages of Hybrid Cloud Architecture: Hybrid
cloud architecture offers businesses flexibility, control, and cost
savings, but it's more complex to manage

5. Multi-Cloud Architecture
● Definition and explanation of Multi-Cloud Architecture: Multi-cloud
architecture is a strategy where businesses use two or more cloud
providers to deploy their IT services and applications.
● Advantages and disadvantages of Multi-Cloud Architecture: Multi-
cloud architecture offers businesses flexibility, cost savings, and
avoids vendor lock-in, but it's more complex to manage.

6. Choosing the Right Cloud
Architecture
Factors to consider when choosing a cloud architecture: When
choosing a cloud architecture, businesses need to consider factors
such as business objectives, security and compliance, cost,
scalability, and technical expertise.

7. Conclusion
● Recap of the main points covered in the presentation: The different
cloud architectures include on-premise, IaaS, PaaS, SaaS, hybrid
cloud, and multi-cloud. Businesses need to choose the right cloud
architecture based on their needs and priorities.
● Final thoughts on the importance of cloud architectures in modern IT
infrastructure: Cloud architectures offer businesses the agility,
scalability, cost savings, and performance they need to thrive in
today's digital economy.
