What exactly is Cloud compute/Cloud computing? Consider the case of a business owner who wishes to establish his company or who desires an IT infrastructure for his company. He consults with the IT-educated person about how to set up an IT infrastructure.
This person was a fantastic information technology specialist who kept up with the latest technical advancements. He was already aware of the Cloud’s technological possibilities. He recommended putting it in the Cloud.
However, the owner’s manager was unaware of the Cloud.
The manager of this company’s owner was conscientious. He was also interested in learning.
The IT person began to explain the technology, as I explain below.
What exactly is Cloud Compute/Cloud Computing?
Cloud Compute is the other name of cloud computing. It is used to deliver online computing services.
What is a cloud in technology? You might be wondering, “What does that mean?”
No worry, I am explaining below.
Cloud is popular for its storage capacity. We can access it anytime, anywhere. We can save the files on the internet with some clicks.
One can take their data in a storage device with themselves.
But it is possible for small data.
What about large data? You are probably not thinking about taking the large storage centers with you.
What is required for Cloud Compute or Cloud computing in technology?
Assume you want to share your document with your colleague. Then you can grant them access. That document is easily accessible to them. You can also give them the ability to edit or delete your document.
The only thing you/your colleague need is the internet.
Let’s move further and talk about or get an understanding of the types of cloud computing.
There are two wide categories of cloud in technology
- Deployment Model
- Service Model
Let’s first talk about the deployment model of cloud in technology
The Deployment model further divides into three categories.
Suppose you want to travel from one city to another. You have three options.
1.Public Cloud: Take a public bus
The public bus lets anyone come and take a seat and pay for it.
You go to the bus stand, sit on the bus and pay the ticket for the seat you occupy. If you want to travel to a far city, you have to pay more. More distance, more you will pay.
Now take this example in the cloud scenario. It represents the Public Cloud. You will pay for that resource only which you used for some time. If the resource time usage is small, you will pay less. If the usage is more, then you will pay more.
This Cloud is managed and owned by cloud providers. It is open to the public.
2.Private Cloud: Buy your car
This option requires a lot of money. The amount to buy a car is huge. You have to pay first. But it has benefits like this is only used by the owner—this example suit for the Private Cloud.
The private clouds are for those organizations that want to run their business solely. They did not like to share it with the general public. It is a one-organization Cloud.
The organization managed the Cloud itself. They may hire a third party to manage their cloud work.
AWS and Vmware are known as the private cloud provider.
3.Hybrid Cloud: Rent a Car
If you want both options to pay for what you use and want a private drive, a taxi is the best option.
You will alone travel by taxi and pay for the travel charges.
This example good representation of hybrid Cloud.
Hybrid is the best option if some want to get the benefits of public and private Cloud. E.g., the secret agencies use private and public clouds.
Private Cloud is for their use where they can save their sensitive data. But public Cloud is used to share non-sensitive data to public or government sectors.
Now take a look at the service model of Cloud computing in technology.
The service model is categorized into three types.
Now you will be confused about which service is good for you. Let me help you to solve this confusion with an example.
1. Infrastructure as service(IAAS) in cloud compute/cloud computing
If you want a virtual machine and are a technical person and know configuring and installing it, go for IAAS.
It is the pay-for-what-you-use model.
IAAS is known for providing basic infrastructure computing. AWS, Azure, and Google are the big players in IAAS. The users of this model are IT administrators.
2.Platform as a service(PAAS) in cloud /Cloud Computing
Suppose you are a developer, wants to test and run the program, then what should you do?
no worry here is PAAS
In this service, you only need a code. This service provides the platform to upload your code and help to run it.
It also provides a simple interface where you can upload the program and debug the application.
The provider will give you a platform or running environment for developing and managing applications. It allows the developer to run the application without running the underlying infrastructure.
You now have the idea that software developers use this Cloud.
3.Software as a service(SAAS) in cloud /Cloud Computing
If you want a ready-made product managed and developed by cloud providers, you should adapt the SAAS. You can access your product anytime, anywhere by internet.
Cloud Provider will provide you with a username and password. Log in with these credentials and get access to the software.
It helps you get rid of the headaches of installing the new setup for the application to run.
You can do your customization according to your needs.
It is a pay-as-you-go subscription. You can be free of worry about the management and installation. All hardware and software are provided and managed by vendors. The users of this are end customers themselves.
Let take a look at an example.
You see the cake and want to bake like this one. Let have a look at options by which you can bake a cake.
Option 1:Represent IAAS
You can bake the cake with your ingredients made by you (flour, butter, egg, sugar water, etc.) by using your oven. Everything is yours. You own all things; vendors manage nothing. This option represents the IAAS, where you have to manage all things.
Option 2:Represent PAAS
You can pick the phone and order the cake. You only need to set the table.
Some resources are of vendors and some of yours.
Option 3:Represent SAAS
You can dine out. It is much simpler; you have not to put in any effort. You go to a restaurant; the table is already set; you order, pay for the cake, eat it, and walk out.
The same is the case with SAAS.Buy the finished product and use it and pay for the finished product.
What are the benefits of cloud computing in technology?
Lastly, take a look at the comparison of Cloud and on-premises to understand the importance of Cloud.
In on-premises, we can’t expect to pay for everything upfront, and there is also an additional operating cost, and it never lets us dynamically scale in.
- Cloud is Pay-as-you go.
Pay-as-you-go type means we use less, pay less in Cloud.
Scale-up: pay more
Scale down: pay less
In contrast to traditional data storage and access methods, such as through a hard drive, cloud computing provides storage over the internet.
There is no need for hardware by end-users.
Databases, networking, software, and servers are some of the computing services available.
Note: Data centers were the first iteration of what is now known as the Cloud. They were the very first technology to use this method of storage.
The servers for on-premises setup occupy a lot of space.
There is not much space requirement is needed for the organization on the Cloud.
A hardware and software management team is required to manage servers setting in on-premises.
There is no need to hire employees to manage the services. They all can get easily controlled by the provider of the Cloud.
Suppose we want to manage the Cloud. The providers will provide the console through which we can manage the Cloud.
Managing the Cloud is much simpler than operating the server directly.
Data Security of cloud in technology and on-premises
On-premises have poor data security. You have to purchase different hardware and software to protect Datacenters or your data of an organization.
Cloud provider provides the security in Cloud. These providers spent a lot of investment giving high security to their consumers’ data and meeting compliance.
In On-premise, data recovery is difficult. Like you have to copy the data in different hardware. The security of this hardware is another matter. There is also a cost of the hardware involved.
The price will be high if you have large organizational data.
If you set up a high-performing replication, then the cost will be much higher than Cloud.
Data recovery is easy in case of any disaster as compared to on-premises. Cloud can recover the data from the online backup system of the cloud.
What happens if I want to restructure my business to meet new-age trends? What should be the Cloud compute /cloud role, and why should I adopt it?
On-premises lack these luxuries. You have to customize all software and hardware manually. The update will be a tedious job for the team.
Cloud is very friendly with new-age trends. It can easily integrate with new environments.
You can easily migrate your existing business to a new one or teardown the old company and build a new one in a few mouse clicks.
There are regular updates that help the maintenance of the Cloud.
There is no need to install the updates manually. They can install updates automatically if you permit them to install the updates automatically on your machine.
Sharing and Access of Cloud/Cloud compute and on-premises
If the valid user needs data outside the organization, they will have to prepare themselves for tedious labor.
If you have a global business and team with an on-premises set up, you know its difficulties in dealing with international clients and employees.
As long as someone has internet, you can give access to anyone in just a few clicks.
In Cloud, many technologies and tools make the businessman’s life easy. You can share and communicate with team members and customers easily.
You can comfortably do business across the other side of the globe.
Implementation of Cloud in technology and on-premises
Talks about the implementation, building an on-premises DC takes time; I was working on a project a few years back, and the goal to make a DC go live at that time was after two years from the date we were speaking about it, but with the Cloud, we can bring our DC in the Cloud within weeks.
After all, this explanation and comparisons and talking about benefits, the manager was fully enlightened and wants to have his IT environment in the Cloud.
