Define Cloud Computing

What is Cloud Computing? 

Cloud Computing provides digital storage, networking resources. cloud computing resources include tools and software such as storage, database, server, networking, and software.  In this, digital files can be stored on cloud-based storage instead of keeping data on proprietary hard drives such as storage on smartphones or computers.

No one is entitled to cloud computing but we get to see a lot of companies offering this kind of service. Companies providing these cloud services enable users to store files and applications on remote servers and then access all data via the Internet. This means that the user must be in a specific location to access it. Is not required, allowing the user to work remotely.

 

In the old days, all big industries were there, they had to make a lot of storage software to store whatever information they had. Because the business needed more storage, to make more storage software. A full team of software developers was required and a full team of experts was required to configure, test, run, secure the software.

 

Today, big companies, big business people work in a large number of companies with cloud computing, they give such work to one such cloud company. And that cloud company has to take care of all the digital work of these companies, change them or increase the services according to the capacity of the company, it can easily do all this work for the companies to manage their own data storage No team will have to be formed and a lot will have to be spent to set up such a big setup. We get to see different plans of cloud computing services leading companies, which are monthly, quarterly, annual, and we can choose the plans according to our work.

Cloud Computing Deployment Models 

In general, there are three main models of Deployment Models of Cloud Computing.

1. Public cloud
2. Private Cloud
3. Hybrid Cloud

Public cloud 

The public cloud service can be used by all types of people. In this public cloud, whatever data we store, we can share it with anyone from the same server, as well as we can easily sync. You can also back up the data very comfortably, but we do not get much security in this type of service. This type of service provides many big companies like Amazon Web Services, Alibaba Cloud, Google Cloud. The public cloud service is quite affordable compared to the private cloud service.

Private cloud

The service of Private Cloud is very similar to that of Public Cloud, but in this service we get to see some advanced features like we get more security in this service, this service is not available to us globally. Or groups can use this type of service. These servers are commonly used by companies that have sensitive information to store, which the companies can keep more secure. In this way, you can get private cloud service from any cloud provider or create your own private cloud center.

Hybrid Cloud

Hybrid Cloud We get to see the features of both the private cloud and the public cloud. In the hybrid cloud, we get to see the goodness of both the clouds, such as our data, software, or such resources, we can keep it private or open to the people, that is, how we can make the data according to our own You can customize it if you want to manage it. That is, if a person or company has a lot of data, some of it is private and some are simple and can be kept in the public domain.

Types of Cloud Computing

1. Infrastructure As a Service -IaaS
2. Platform As a Service -PaaS
3. Software As a Service -SaaS

Infrastructure As a Service -IaaS

It is the most common service model of cloud computing because it provides the fundamental infrastructure of virtual servers, networks, operating systems, and data storage drives. This allows for the flexibility, reliability, and scalability that many businesses want for this type of cloud service and removes the hardware requirements we need from such service. Infrastructure as a service is a fully outsourced pay-for-use service and is available as a public, private, or hybrid fundamental infrastructure.

Platform As a Service -PaaS

Platform As Service -PaaS is the second most important model of cloud computing here, in which if we take such a model then we get to see some kind of services in this, including the operating system, web application, as well as the database. These are the services we get in this model. Such service is available to us in Google App Engine where we can develop and run web applications in our own way.

 

Software As a Service -SaaS

Software As a Service -SaaS In this cloud model, the main task of delivering different types of software applications to its customers. SaaS is the most commonly used customer relationship management, help desk, HR solutions, and billing and invoicing. This service is used in many such applications, and many such applications provide this cloud model. With the help of this model, cloud providers develop the app with their physical resources and provide it to the customer.

Common Examples Of Cloud Computing

Cloud Service Provider - Google Drive, Dropbox, One drive

Cloud Service Provider

Today, if we talk about India or the whole world, we get to see cloud computing services everywhere. Many people would also use it. And there are many people who use cloud computing but they have no knowledge of this. Today 90% of the people in the world use Android smartphones and talk about computers, we use Windows base computers more and with them, we are provided some free cloud computing ie cloud space, this includes names like Google's Google Drive, Microsoft's (Microsoft )'s One Drive, Apple's (Apple's) I Cloud, Dropbox are such a lot of cloud providers that we are using in our smartphones, laptops, computers.

Google Drive

It is the most used cloud computing service, where all storage is found online, so it can work with cloud productivity apps (Google), Google Docs, Google Sheets, and Google Slides. (Google) Google Drive: We get to see many such services in the cloud space of Google. We can use it on all types of operating systems like Android, iOS, Windows, along with this, Google has its own apps that run completely on the cloud such as Google Photos, Google Contact, Google Calendar, and so on. We can access many services from cloud space. Google gives us up to 15 GB of storage for free.

One Drive

If you are using any Microsoft Windows laptop or computer, then you must have heard about One Drive. One Drive, which is a cloud service from Microsoft, in this we can save all our kind of digital data, here One Drive is considered very secure. In One Drive, we get very good services like in the X-Box coming from Microsoft, we can play games with very good graphics due to cloud computing, without any storage and good RAM. And hardware.

Apple Income Cloud (iCloud)

Apple Income Cloud This is a cloud service from Apple. It is mainly used for storing a lot of things like storage, backup, synchronization (mail, contact, calendar). Apple's service is found in the income pad, income phone, mac book. If a device is lost, then it can easily find a smartphone with the help of the Find (i phone) feature.

Cloud Computing Security Architecture

If you talk about cloud computing security, then your cloud infrastructure is only as secure as you build it. Security teams not only have the responsibility of securing cloud storage but it also becomes our responsibility. We often hear the data of iCloud leaked, there have been many incidents of data leaked from Facebook, which proves that 100% of any service does not protect our data.

 In order to keep our data secure, we also have to pay attention to many things such as if our data is very sensitive, then we need to keep it in the private cloud because Proxy Cloud is much more secure than public cloud. Today there are many such companies who want to start cloud service but are not moving about security.

Talk about Infrastructure Security, this includes our hosts and virtual machines, then our network level security, and our web application security. All this security comes in. In infrastructure security, we get to see three levels of security, the first is Host and Virtual Level Security, the second. Application Level Security, and Third Network Level Security.

 Hosts and virtual level security provide security to our hosts and virtual machines that perform our tasks virtually. After that, the network level security, which has all the internet connections, the work of securing those servers takes place at this level, after that comes to the application level security, in which we have the task of securing the application provided. But to make it secure, we need a better platform, thus providing cloud provider protection to users at different levels in different ways.
