Módulo 5 - Deployment Models

Summary

This video script explores the three primary cloud computing deployment models: public, private, and hybrid. It highlights their key differences, including cost, security, and control over resources. The public cloud is cost-effective but offers less control, while the private cloud provides enhanced security at a higher cost. The hybrid model combines both, offering flexibility but adding management complexity. The script uses the example of a bank to illustrate when each model might be chosen based on security and availability needs, helping viewers understand the practical applications of these cloud models in business.

Takeaways

• 😀 The script discusses three main cloud deployment models: public, private, and hybrid cloud.
• 😀 Public cloud refers to resources like applications and storage services that can be accessed over the internet, often for free or paid on a usage basis.
• 😀 Public cloud is popular among businesses because it requires no major upfront investment in IT infrastructure, personnel, or equipment.
• 😀 A private cloud offers more control and security, as resources are dedicated to a single organization, but it comes with higher costs for infrastructure and maintenance.
• 😀 A hybrid cloud model combines the benefits of public and private clouds, allowing businesses to optimize costs while maintaining control over sensitive data.
• 😀 Security risks and the need for high availability can lead businesses like banks to choose private cloud for certain services.
• 😀 The public cloud is cheaper but less secure compared to the private cloud, which is more costly but offers better security and control.
• 😀 Hybrid cloud allows businesses to place non-sensitive services on the public cloud while keeping sensitive data on the private cloud, offering a balance between cost and control.
• 😀 Implementing a hybrid cloud can be complex, requiring careful management of resources and services across both private and public clouds.
• 😀 The next chapter will discuss cloud computing services and models, including IaaS (Infrastructure as a Service).

Q & A

What are the three most common cloud deployment models discussed in the transcript?

The three most common cloud deployment models discussed are public cloud, private cloud, and hybrid cloud.

How is the public cloud model described in the transcript?

The public cloud model is described as a model where resources like applications and storage services are accessible over the internet. It is often low-cost or free initially and operates on a pay-as-you-go basis, making it attractive to businesses due to its lower upfront costs.

What is the main advantage of using a private cloud for an organization like a bank?

The main advantage of using a private cloud for a bank is the enhanced security and high availability, as the bank can ensure that no one outside its organization has access to sensitive data.

What are the trade-offs associated with adopting a private cloud model?

The trade-offs of adopting a private cloud model include higher costs due to the need to invest in infrastructure, equipment, and personnel for maintenance, but it offers greater control and security over resources.

What does the hybrid cloud model allow an organization to do?

The hybrid cloud model allows an organization to combine the best aspects of both public and private clouds. For example, it can place sensitive data in the private cloud while utilizing the public cloud for less critical services, optimizing both security and cost efficiency.

Why might the hybrid cloud model introduce management complexities?

The hybrid cloud model can introduce management complexities because it requires coordinating between two different types of clouds, which may involve additional complexity in terms of integration, monitoring, and security management.

What is the main disadvantage of using a public cloud compared to a private cloud?

The main disadvantage of using a public cloud is the potential lack of control and security, as resources are shared with other organizations, which may not meet specific security or high availability requirements.

How does the cost of a public cloud deployment compare to a private cloud?

The cost of a public cloud deployment is generally lower upfront, as it eliminates the need for significant investment in infrastructure and maintenance. In contrast, a private cloud deployment requires high initial costs for equipment and personnel.

In what scenarios would a public cloud be less suitable for an organization?

A public cloud would be less suitable for an organization if there are strict security or high availability requirements that the public cloud cannot reliably meet, such as for critical financial services in a bank.

What is the purpose of asking the question about which cloud deployment model functions entirely behind a corporate firewall?

The purpose of this question is to assess understanding of which cloud model, specifically the private cloud, operates entirely within an organization's internal network, ensuring security and control.
