Let's talk about the different different cloud deployment models
there. Three different cloud deployment models.
The Cloud Department model defines where your data is stored and where your applications are running.
If your data and applications are all on premises, this is called a private club.
If your data an application is on infrastructure that is managed by a cloud vander like azure, AWS, Google and so on. This is called a public crowd.
If your data and applications are stored in, manage either home premise on end on the cloud and there is communication between different components of these infrastructure. This is called a hybrid cloud.
They're certain benefits and disadvantages of each one off approach. Let's talk about the private cloud first.
One of the benefits of the private cloud is that you can support any scenario
because you have complete control of the infrastructure. You can install any kind of applications, even legacy applications that are not cloud enabled in random. On your private club.
Once a sorry mentioned, you have complete control of the infrastructure as well off the security of your private club. You can implement this security as a swear what you want and you can completely control it.
You can meet any security compliance and legal requirements using the private cloud.
However, some of the disadvantages are there is significant initial cost and this is capital expenditure as we talked before.
In orderto build these private cloud,
there is a limits to agility. For example, if you have exponential growth, you need to constantly invest new money in order to build bigger and bigger data centers.
And, of course, you have demand for writing skills and expert eyes in order to manage these private cloud. Keep in mind that with the private cloud, you also need to build some automation or install the cloud software inside your private data center in orderto easily manage those three sources.
What about the public cloud?
Well, theoretically, the public cloud. Here's high skill and agility. You don't need to walk. Think about acquiring new hardware in orderto actually scare your work. What's this is a job done by the cloud vendor.
Of course, one of the benefits is that the public cloud has also pay as you go pricing, which means that you only pay for the things that you use and you don't pay if you don't need something infrastructure.
You don't have any hardware and data center maintenance requirements with the public clouds.
And, of course, you need lower technical skills of requirements in orderto manage infrastructure in the public cloud. You don't need tohave Carter networking skills. You don't need to give hardware storage skills. You can actually do this just with developers.
Of course, one of the disadvantages is that you cannot support all legacy scenarios there. Certain applications that are not applicable for the public cloud because they require lower carbon access toe some functionality.
In certain cases, you may not be able to meet all compliance needs. If you use a public cloud
you don't have control over the hardware in the service is which means that you are dependent on the cloud vandal. If something needs to be enabled, sometimes such things may not be enabled for security or other reasons by the cloud vandal
and last. Some security requirements may not be met because the public cloud is, ah, multi tenant infrastructure and
some of the security requirements required. Dedicated instances card were instances for running your application.
This is where the hybrid cloud comes in.
Using the hybrid cloud. You can support any scenario, whether its legacy or modern clouds scenario. You can deploy it, and you can choose the infrastructure where your application runs.
You kept flexibility of choice for the applications so you can legacy applications on your private site, and you can earn more than applications on the public side,
you can implement specific security and compliance requirements, and you can satisfy any one of those because you have the choice between the private and the public side.
Of course, you can take advantage of the economies of scale because the cloud bands or takes care of bringing more infrastructure when you need it. In the public side,
One of the disadvantages of the fiber club is once again the requirement for initial investment to build your private data center.
And it may be hard to set up and maintain because it requires more knowledge on the private side, as well as communication between the private and the public side.
