What is Cloud Computing?
Cloud computing is simply called “the cloud”, is the delivery of on-demand computing resources ( CPU, RAM, Video Card, Network Speeds, Storage, O/S, Software ) everything from applications to information centers to offer faster innovation, flexible resources and economies of scale over the internet on a pay-for-use basis.
Types of Cloud Computing:
Cloud computing is divided into two categories:
- Deployment Model
- Service Model
- Deployment Model
It is further divided into three categories:
i. Public cloud: This type of cloud infrastructure is available to the general public whoever has access over the internet and is owned by a cloud provider. Example: AWS, Microsoft Azure, etc.
ii. Private cloud: This type of cloud infrastructure is mainly operated by a single organization. It can be managed by the organization or a third-party and can be on-premises or off-premises. Example: AWS, VMware, etc.
iii. Hybrid cloud: It has the behavior of both public and private cloud. In this type of infrastructure, it is very likely yours but you only pay for the time you use and don’t pay all the upfront.
- Service Model
It is further divided into three categories:
i. Infrastructure as a service (IaaS): It is a cloud service that provides computing infrastructure. In this only you have to manage the infrastructure and everything else will be managed by the vendor. You pay for what you use services are available. Here the users are IT Administrators.
ii. Platform as a service (PaaS): It provides a cloud platform and run-time environment for developing, testing and managing applications. In this all the infrastructure and software are managed by the vendor only you have to select the platform. It allows software developers deploying applications without requiring all related infrastructure. Here the users are Software developers.
iii. Software as a service (SaaS): It is a cloud service that provides software and hardware. In this, all the hardware and software are managed by the vendor so you don’t have to maintain anything. Here the users are End users.
Some of the Cloud Providers:
There are many cloud providers such as:
- AWS (Amazon Web Service): AWS is a cloud computing service provided by Amazon. It provides a mixture of infrastructure as a service and platform as a service path and packaged software as a service called SAS offering.
- Microsoft Azure: Microsoft Azure is commonly known as Window Azure is a cloud computing provided by Microsoft. It provides some specialized tools for using the cloud for building, testing, deploying and managing the applications through the service throughout the global network that Microsoft manages. It also provides software as a service, platform as a service and infrastructure as a service and it supports lots of different programming languages and tools and including both Microsoft and third-party software.
- IBM Cloud: It is a cloud computing service offered by IBM. IBM also includes software as a service, platform as a service and infrastructure as a service. Now the difference is that it offers through public, private and hybrid cloud delivery.
- VMware: It is a subsidiary of DELL technologies and provides cloud computing and platform virtualization software and services. It is the first commercially successful company to visualize the x86 architecture.
- Google Cloud Platform: It is offered by Google. It’s a suite of cloud computing that runs on the same infrastructure that Google uses for its end- users products such as the Google search and the YouTube you are familiar with alongside with a set of managed tools. It also provides cloud service including computing services, data storage services, data analytics, and machine learning services.
- Digital Oceans: Digital oceans provides developer cloud services that help to deploy and scale applications that run simultaneously on several computers. It’s headquartered at New York City with data centers worldwide. In January 2018, Digital Ocean was the third largest hosting company in the world in terms of web facing.
And there are many more companies such as iCloud, Kamatera, Rack-space, Adobe, etc.
How does Cloud Computing Services work?
The working of cloud computing is very simple. It is divided into two ends. First one is the Front End and the second one is the Back End. The front end is the client’s computer or computer network and also the application needed for accessing the data. The back end is the cloud section of the network. It consists of all the servers, storage, and various computers and each application have its own dedicated server.
How does Cloud Storage work?
Cloud storage is online storage which is only accessible over the internet offered by some companies. The company has access to your data that you will be able to analyze, manage, add to and transfer it from a single dashboard.
It doesn’t matter where you are or where the data is, just in one tap you can access your data over the internet.
Only you have to do that purchase cloud storage and create an account and upload your files on the storage. Depending on the storage you need prices to vary. But most of the company offers you free storage of a minimum of 5 GB or a maximum of 50 GB.
Risks of Cloud Computing Services:
- Privileged users access: It is a big risk because of its accessibility that they provide to the users to access the organization system and knowledge. By using this account, they can access the valuable data, shut out legitimate users and make ghost account and backdoors that cannot be seen.
- Regulatory compliance: Every user present on the cloud are liable for the safety and integrity of their own information even if it is supplied by a service provider. The suppliers of the service provider are subjected to external audits and security certifications.
- Data location: While using the cloud, you can’t say exactly where the data is hosted. You can’t even say which country it is stored.
- Data segregation: The data stored in the cloud is available to everyone who is authorized.
- Recovery: A cloud provider won’t tell you what will happen if your data is crashed, even if you don’t know the exact location where it is stored.
Uses of Cloud Computing services:
Most probably every in the world is using cloud computing. As you know you are using an email account and using it. But you where the message is stored, or where they are sent. This is an example of cloud computing as you are using it but no space is required for the messages or documents to store on your computer storage. There are many uses of cloud computing such as you can create a new app, test it and analyze it. You can also store data, backup data as well as recover it. You can stream audio and videos. You can deploy software and deliver it.
Benefits of Cloud Computing Services :
- Speed: Most of the cloud provider provides cloud storage on demand and self-service, this is why a large amount of data can be accessed in a single click.
- Scalability: You can deliver data on your own choice more or less as it is elastic.
- Cost: You pay for what you use. Prices vary on the demand for the storage you require.
- Performance: The largest cloud computing services run on a wide network of secure data centers, which gets updated to the latest generation of fast and efficient computing hardware.
- Automatic software update
- Increased collaboration
What Can be future?
There are many potentials and capabilities in cloud computing technology. In the upcoming years, most of the non-cloud apps are going to move to the cloud. Cloud computing is going to make a new world job, service, platforms and much more. Businesses and organizations might organize themselves and conduct their businesses much more affordable and professionally with cloud technology. Social networking and connecting with friends and family may get easier as well. The end users will also get benefited with cloud technologies, they would get the seamless experience of their favorite app irrespective of their system performance.
