Chapters

• 00:00 - 00:30: Introduction and Overview of Cloud Deployment Models This chapter introduces cloud deployment models, highlighting their significance in IT infrastructure. Adam welcomes viewers to the sixth episode of the fundamentals course. He mentions that the focus will be on the differences between public, private, and hybrid cloud models. It's essential for exam preparation to understand these distinctions. The chapter begins with an exploration of the public cloud.
• 00:30 - 02:00: Understanding Public Cloud This chapter introduces the concept of public cloud, highlighting the distinct separation between deploying services with a cloud service provider versus a personal datacenter. It emphasizes that with public cloud, all resources are hosted by the provider, eliminating the need for personal hardware ownership. It briefly notes that services in the public cloud often share hardware with other customers, a situation commonly managed by service selections.
• 02:00 - 03:00: Advantages and Disadvantages of Public Cloud This chapter provides an overview of the public cloud, focusing on its advantages and disadvantages. The key advantage discussed is the elimination of capital expenditure (capex), meaning there is no need for a large initial investment from the user. The chapter also mentions considerations like selecting the right pricing tier and adhering to security compliance policies when starting with the cloud. The public cloud is described as simple to understand, but it is implied that there are trade-offs in terms of deployment model choices.
• 03:00 - 05:00: Limitations and Ownership in Public Cloud The chapter titled 'Limitations and Ownership in Public Cloud' discusses the benefits of moving to the cloud, primarily focusing on the pay-as-you-go pricing model. This model allows organizations to pay only for the resources they use, eliminating the need for hardware maintenance and thereby reducing the need for deep technical skills within teams. However, the chapter also acknowledges a significant disadvantage related to security and compliance. While the cloud is secure by default, there are still challenges that users must manage.
• 05:00 - 05:30: Introduction to Private Cloud The chapter discusses the limitations of public clouds in meeting specific security requirements, government policies, industry standards, or legal obligations. It highlights the issue of ownership, where users cannot maintain or modify hardware because it's managed by providers like Microsoft in their own data centers. It suggests scenarios where a public cloud might not be the ideal choice, especially when specific compliance or customization needs exist.
• 05:30 - 07:00: Advantages and Disadvantages of Private Cloud This chapter discusses the model of private clouds as an alternative to public clouds. It highlights that private clouds involve hosting everything in one's own data center, rather than utilizing shared resources over the internet as in public clouds. The core idea is to offer all the benefits associated with cloud computing, such as scalability and flexibility, within a privately managed infrastructure. The chapter emphasizes the importance of self-service and maintaining control over hardware as integral elements when implementing a private cloud solution.
• 07:00 - 07:30: Hybrid Cloud Model This chapter discusses the hybrid cloud model, specifically focusing on the advantages and disadvantages of using a private cloud. The advantages include total control over security, the ability to support any scenario, and meeting any security and compliance requirements. However, these benefits come with the downside of high initial capital expenditure for hardware, and limited agility.
• 07:30 - 09:00: Conclusion and Additional Resources The conclusion summarizes the limitations and costs associated with running a private cloud, emphasizing the necessity for excellent internal skills and expertise to manage it effectively. It also introduces the hybrid model, which combines both public and private cloud solutions to maximize flexibility, providing a middle ground in terms of benefits between the two types of cloud deployment.

• 00:00 - 00:30 Oh guys welcome back my name is Adam and this is the sixth episode in our fundamentals course this time we will be talking about cloud deployment models and their key differences stay tuned in our previous episode we learned about service type models this time we will be learning about the deployment models this section of the exam will test you whenever you know what is a public private and hybrid cloud and what are their differences let me start with a public cloud in order to understand the
• 00:30 - 01:00 public cloud we need to make a very clear separation of where we are deploying our services we are either deploying them to the cloud service provider or inside of our own datacenter when it comes to the public cloud that means all our resources are hosted in a public cloud that means we don't own our own Hardware anywhere anything to note is that in public cloud some services share the hardware with other customers this usually is solved by just picking
• 01:00 - 01:30 the right pricing tier but you should be aware of that when you're starting with the cloud and you have some security compliance policies in place the public cloud is very simple to understand in general you're hosting everything in public cloud as in any deployment model there are always advantages and disadvantages in this case when it comes to advantages there's no capex there's no capital expenditure that means no big initial investment on your side with cloud being highly available and a drive
• 01:30 - 02:00 by default to get those all advantages by just simply going to the cloud thanks to pay-as-you-go pricing and this consumption model that we're talking about you only pay for the resources that you use and because Microsoft manages all of the hardware there's no hardware maintenance required and as such no deep technical skills required from your teams while there are some disadvantages there is one major one when it comes to security in compliance as well cloud is secure by default there
• 02:00 - 02:30 may be specific security requirements or government policies industry standards or legal requirements the public clouds cannot meet in that case the public cloud might not be there right choice for you there's always an issue with ownership because if you want to maintain your own hardware or make changes to the hardware then again you cannot do that because Microsoft is hosting all the hardware and managing all the hardware in their own data centers and if you have some specific
• 02:30 - 03:00 unique business requirements and again public cloud might not be the one for you and on the other hand we have private cloud which is reverse model you don't have anything in public cloud you host everything in your own data center in here remember that you need to provide the self service in order to be Ashley consider cloud and you need to provide all the benefits of the cloud except in your own data center in this scenario you are the one maintaining all the hardware so let's talk about the
• 03:00 - 03:30 advantages and disadvantages of using private cloud advantages are pretty obvious because you maintain everything you have all the possibilities so you can support pretty much any scenario you have total control over the security and as such you can meet any security and compliant requirements but maintaining your own hardware comes at a cost and that cost is a big initial capital expenditure investment that you need to make there's a limited agility because
• 03:30 - 04:00 that agility is limited by the amount of hardware and skills of your team so excellent skills and expertise of your internal team is pretty much mandatory when running private cloud and as you can imagine this comes at a cost which brings us to the third model which is the hybrid model in this model you take advantage of both public and private cloud you connect them together to provide the greatest flexibility out of those free options so when talking about the advantages in disadvantages the
• 04:00 - 04:30 obvious one is the great flexibility but beyond that you can run legacy applications in your private cloud utilize existing infrastructure meet any security requirements but for everything else move to the cloud and take advantage of all the good stuff from the cloud in this case the disadvantages are pretty obvious bigger environment consisting both public and private cloud might be more expensive but is definitely more calm applicated to manage an Assad puts a
• 04:30 - 05:00 bigger strain and bigger requirement on the skills and expertise of your internal IT teams but that's pretty much it when it comes to those free models if you want to learn more go to my website - episode 6 and check the study guide for this episode there are some official materials about the cloud deployment models there's episode cheat sheet and the practice test if you want to check what you have learned during this episode and that's it for this episode I appreciate every single one of you that stayed until the very end if you like what I do
