objectives for this video include understanding the role that abstraction and automation plays and cloud computing, and they're discussing the high level benefits of cloud.
But start by expanding a little bit further on cloud versus traditional virtual ization. Because Cloud isn't just a bunch of virtual machines,
the abstraction separating the
logical resource is from the underlying physical infrastructure is a major, major point of cloud. It allows us to create resource pulls out of the underlying assets right. The cloud provider can then allocate those to the individual consumers or tenants. Cloud users within their
the automation and orchestration allows that to happen rapidly without requiring direct interaction of the cloud provider,
right. So if you say you want a virtual machine, you don't have to call the cloud provider and get one spun up. They provide you with automated mechanisms, which we'll talk about in more detail, and you may already have been exposed to it. But this is a very important what distinguishes cloud from just a bunch of traditional virtual machines, the abstraction piece
using it to build a resource pool.
And a lot of times, if we think about and look at the traditional down at the bottom.
The abstractions there. But you're still needing to to call somebody when you want it right that the self service automation piece is minimal in the traditional models and with cloud, it's a real big cornerstone of the way things operate.
So what are some of the benefits of cloud? Right? We've really nailed home what it means. But
how about benefits? So having that self service capability, the orchestration, that automation using a shared pool of resource is well provides agility to the cloud user, you can expand in a public cloud. You don't have to purchase new hardware, right? If you want to expand the amount of storage, the amount of servers,
everything is software to find. So this includes the networks, the machines and so forth.
That's really, really valuable. When you start thinking about change management of your infrastructure itself and re creating an environment
where you know that the content in the architecture of that environments, it matches other environments. So say you have a development environment, acu environment and production environment, and you then want to introduce a stage environment which really should mere production. Well, how do you know that it's going to be right. And having that software infrastructure is a code
which, by the way of it,
different class that you confined terra form, which is one of the mechanisms to realize that is very valuable in that sense. So let's talk about resiliency as well. Reducing downtime, disaster recovery. These air major benefits because the cloud providers
have those resource is and they usually have the larger ones, especially multiple data centers, multiple physical wrote locations with these re sources that are highly connected and and have real low laden see connections between the two. So if there's a power outage in a building, or if there's a massive network outage on the whole side of the country,
you're re sources can be
redeployed or even automatically fail over into other areas. So some real, just dramatic resiliency that you could put in place, and doing it in a traditional model could be very expensive would be very expensive for smaller companies. But even larger companies having to manage multiple data centers
across the globe, the costs of the employees getting the hands
on the ground could be a very costly proposition, and this is something that cloud brings in eight Lee, with its design, the economics being able to scale up and down quickly if you need a lot more storage or if you don't write because we have that resource pool and it's the cloud providers making sure that that resource pool has capacity
and you don't then have to spend capital and
and go out and invest your time managing the hardware elements of it right toe optimize resource utilization. I like to think of it as economically. It's a form of outsourcing, right? You are outsourcing the management of your physical infrastructure to these cloud providers.
Of course, if it's a private cloud, you're not outsourcing it. You're managing yourself.
But even in that scenario, the details of that are being offloaded to in a different internal group that is responsible for managing that private cloud
and then last but not least, security, which is the real tenants around the hold certification here and cloud security. It has some riel economic benefits for the cloud provider themselves to keep security up and running right. Um,
obviously, there is that the physical layer they need to make sure things were there when you have the multiple tenants, you need to make sure that they're isolated and segregated so that they can't penetrate and get into even competitors. Right, get into other other tenants infrastructure and servers and purport any sort of attacks or takeovers.
So did they have a very big,
uh, incentive to make sure that they're keeping their systems secure and their facilities secure At that layer, however, security is a shared responsibility, and we're gonna hit on this again and again
through the coming course materials is because as a cloud user, there are certain elements and settings that you have a new control and you're responsible for. And so the cloud can provider is certainly going to take care of the physical. And then, as we move up the ladder, there more responsibilities that
are going to sit on the cloud provider
and less responsibilities on the cloud user. And so with that,
we're going to wrap up this video and a summary of what are the things we talked about and learned right
cloud computing, it really is. A new operational model combines the benefits of abstraction, automation, and it's a new way of delivering technology in consuming technology as a business, as an organization, as an individual on as a wide range of benefits. So it underlying physical infrastructure is abstracted through virtual ization,
automation and orchestration. We're gonna hit on this again and again and again
provisioning virtualized assets to create these resource pools. Right? We talked about how can cloud improve agility, economics, resiliency. And last but not least, we touched on the security and the shared responsibility aspect of security. And we're going to dive into that deeper,
so I look forward to seeing you in the next video.
