Understanding Different Cloud Deployment Models

1. Public Cloud ☁️

Hosted by third-party providers like AWS, Microsoft Azure, and Google Cloud.

Easily accessible over the internet.

Ideal for sharing non-sensitive data.

Scalable, cost-effective, and no need for in-house infrastructure.

2.Private Cloud 🔒

Also called Enterprise Cloud.

Used by organizations to store confidential and sensitive data. 🗄️🔐

Not shared with other entities.

Access is restricted and secure, typically only available within the company. 🏢🔒

Example: A company like Dell may have its head office in the USA, with branches in Delhi, Canada, Lahore, Kabul, and New Delhi. The head office may use a private cloud to secure internal data while allowing remote access to other branches through encrypted connections. 🌍🔗

Only authenticated internal users can connect, preventing unauthorized access or hacking. 🚫🔓

Advantages of Private Cloud: Enhanced security and privacy. 🛡️

Greater control over data and infrastructure. ⚙️

Disadvantages: Higher cost due to server maintenance. 💰

Requires skilled personnel to manage infrastructure. 👨‍💻👩‍💻

Scalability is limited compared to public cloud. 📉

Physical servers must be maintained in-house or virtualized for cloud use. 🖥️

3.Hybrid Cloud

Combines Public and Private Cloud infrastructures. ☁️🔗

Provides flexibility to manage sensitive data on a private cloud and use public cloud services for less critical operations. 🔒☁️

Enables optimized resource utilization and cost savings. 💼💰

Ideal for businesses needing data security and scalability simultaneously. 🛡️📈

4.Understanding Virtual Private Cloud (VPC) Offered by cloud providers like AWS and Azure.

Mimics a private cloud but runs on public cloud infrastructure. ☁️🔒

Offers one-to-one connectivity and restricted access. 🔗🚫

Suitable for businesses seeking cost-efficiency with privacy. 💰🔐

Note: VPC is not a real private cloud but behaves like one virtually. 🌀
