Cloud Computing In 6 Minutes | What Is Cloud Computing? | Cloud Computing Explained | Simplilearn

A concise guide explaining cloud computing, its benefits over on-premise systems, deployment and service models, and key features.

Key Takeaways

Cloud computing is more cost-effective and scalable than on-premise computing.
It reduces the need for physical infrastructure and maintenance teams.
Cloud offers better data security and disaster recovery options.
Understanding deployment and service models helps choose the right cloud solution.
Cloud computing enables businesses to focus on core activities without IT infrastructure hassles.

What the video covers

Cloud computing enables scalable, pay-as-you-go IT resources over the internet, ideal for businesses with fluctuating demands.
On-premise computing requires significant upfront infrastructure, space, and maintenance costs, with limited scalability.
Cloud computing offers easier scaling, better cost efficiency, and reduced maintenance by shifting responsibilities to providers.
Server storage in cloud computing is managed by providers, saving physical space and reducing power and maintenance hassles.
Cloud computing provides superior data security and robust disaster recovery compared to traditional on-premise setups.
There are three deployment models: public cloud (shared infrastructure), private cloud (exclusive infrastructure), and hybrid cloud (combination).
Cloud service models include Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), each offering different levels of management.
IaaS provides basic computing infrastructure, PaaS offers a platform for application development, and SaaS delivers fully managed software applications.
Cloud computing allows businesses to avoid the hassles of owning and maintaining IT equipment by relying on cloud providers.
Popular cloud platforms include Microsoft Azure and Google Cloud Platform, each with unique features and services.

Chapters

What are the main advantages of cloud computing over on-premise systems?

Cloud computing offers easier and faster scalability, pay-as-you-go pricing, reduced maintenance costs, better data security, and robust disaster recovery compared to on-premise systems.

What are the different cloud deployment models?

There are three deployment models: public cloud, where infrastructure is shared and available over the internet; private cloud, which is exclusively operated for one organization; and hybrid cloud, which combines both public and private clouds.

What are the key cloud service models and their differences?

The three main cloud service models are Infrastructure as a Service (IaaS), which provides basic computing resources; Platform as a Service (PaaS), which offers a platform for developing applications; and Software as a Service (SaaS), which delivers fully managed software applications.

Imagine you're the owner of a small software development firm, and you want to scale your business up. However, a small team size, the unpredictability of demand, and limited resources are roadblocks for this expansion. That's when you hear about cloud computing. But before investing money into it, you decide to draw up the differences between on-premise and cloud-based computing to make a better decision.

Speaker A

once you've scaled up it is difficult to scale down and often leads to heavy losses in terms of infrastructure and maintenance costs cloud computing on the other hand allows you to pay only for how much you use with much easier and faster provisions for scaling up or down next let's talk about server storage on-premise systems need a lot of space for their servers notwithstanding the power and maintenance hassles that come with them on the other hand cloud

Speaker A

When it comes to scalability, you pay more for an on-premise setup and get fewer options too. Once you've scaled up, it is difficult to scale down and often leads to heavy losses in terms of infrastructure and maintenance costs. Cloud computing, on the other hand, allows you to pay only for how much you use, with much easier and faster provisions for scaling up or down.

Speaker A

for data recovery with on-premise setups are very small in contrast cloud computing systems have robust disaster recovery measures in place to ensure faster and easier data recovery finally we have maintenance on-premises systems also require additional teams for hardware and software maintenance loading up the costs by a considerable degree cloud computing systems on the other hand are maintained by the cloud service providers reducing your costs and resource allocation substantially

Speaker A

Next, let's talk about server storage. On-premise systems need a lot of space for their servers, notwithstanding the power and maintenance hassles that come with them. On the other hand, cloud computing solutions are offered by cloud service providers who manage and maintain the servers, saving you both money and space.

Speaker A

there are three types of deployment models public private and hybrid cloud imagine you're traveling to work you've got three options to choose from one you have buses which represent public clouds in this case the cloud infrastructure is available to the public over the internet these are owned by cloud service providers two then you have the option of using your own car this represents the private cloud with the private cloud the cloud infrastructure is exclusively operated

Speaker A

Then we have data security. On-premise systems offer less data security thanks to a complicated combination of physical and traditional IT security measures, whereas cloud computing systems offer much better security and let you avoid having to constantly monitor and manage security protocols. In the event that a data loss does occur, the chance for data recovery with on-premise setups is very small. In contrast, cloud computing systems have robust disaster recovery measures in place to ensure faster and easier data recovery.

Speaker A

virtualization and middleware cloud computing service models are hassle-free is refers to infrastructure as a service it is a cloud service model where users get access to basic computing infrastructure they are commonly used by it administrators if your organization requires resources like storage or virtual machines is is the model for you you only have to manage the data runtime middleware applications and the os while the rest is handled by the cloud providers next we have pass

Speaker A

Finally, we have maintenance. On-premise systems also require additional teams for hardware and software maintenance, loading up the costs by a considerable degree. Cloud computing systems, on the other hand, are maintained by the cloud service providers, reducing your costs and resource allocation substantially.

Speaker A

operating systems servers storage and others are handled by the cloud service providers and finally we have sas sas or software as a service involves cloud services for hosting and managing your software applications software and hardware requirements are satisfied by the vendors so you don't have to manage any of those aspects of the solution if you'd rather not worry about the hassles of owning any it equipment the sas model would be the one to go with with sas the cloud service provider

Speaker A

So now, thinking that cloud computing is a better option, you decide to take a closer look at what exactly cloud computing is. Cloud computing refers to the delivery of on-demand computing services over the internet on a pay-as-you-go basis. In simpler words, rather than managing files and services on a local storage device, you'll be doing the same over the internet in a cost-efficient manner.

Cloud computing has two types of models: deployment model and service model. There are three types of deployment models: public, private, and hybrid cloud. Imagine you're traveling to work. You've got three options to choose from. One, you have buses, which represent public clouds. In this case, the cloud infrastructure is available to the public over the internet. These are owned by cloud service providers.
