Cloud-Based Computing: A Simple Introduction


Written by Zoya khan

I don’t need a hard disk in my computer if I can get to the server faster… carrying around these non-connected computers is byzantine by comparison— Steve Jobs

What is cloud-based computing?

Cloud-based computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of purchasing, owning, and maintaining data centers and servers, you can access technical services, such as computing power, storage, and data, on the basis required from a cloud provider such as Amazon Web Services (AWS).


Who is using Cloud-based computing?


Organizations of all types, sizes, and industries use the cloud for a number of purposes, such as data storage, disaster recovery, email, virtual desktops, software development, and testing, big data analysis, and customer-focused web applications. For example, healthcare companies are using the cloud to develop personalized treatments for patients. Financial services companies are using the cloud to bolster real-time adoption and fraud. Video game makers are using the cloud to deliver online games to multiplayer around the world.



Benefits of Cloud-based computing:


  1. Agility- The cloud gives you easy access to a wide range of technologies so you can quickly launch and build anything you can think of. You can quickly start the resources as you need them - from infrastructure services, such as compute, storage, and data, to the Internet of Things, machine learning, data pools, and analytics and much more.

  2. Elasticity- With cloud computing, you do not need to allocate additional resources to manage higher levels of business in the future. Instead, you provide the resources you need. You can measure these services up or down so they can grow faster and lose weight as per your needs.


Types of cloud computing


There are basically three main types of cloud computing which include Infrastructure as a Service, Platform as a Service, and Software as a Service.


· Infrastructure as a Service (IaaS)- IaaS contains basic building blocks for cloud IT. It usually provides access to communication features, computers (virtual or dedicated network), and data storage.


· Platform as a Service (PaaS)- PaaS pulls out the need to manage sub-infrastructure (usually Hardware and applications) and allows you to detect the deployment and management of your applications.


· Software as a Service (SaaS)- SaaS provides you with a complete product that is run and managed by the service provider. In most cases, people referring to SaaS are referring to end-user applications (such as web-based email).


Cloud computing offers your business many benefits. It allows you to set up a virtual office base to give you the flexibility to link your business anywhere, anytime. In today's era of rapid climb of web-enabled devices used in the business environment (e.g. smartphones, tablets), accessing your data is much easier.

In today's era of rapid climb of web-enabled devices utilized in the business environment (e.g. smartphones, tablets), accessing your data is far easier.


Advantages of Cloud Computing


Cloud-based software offers firms across all sectors a wide variety of advantages, including being able to use any device software via a native application or browser. This allows users to transfer their files and settings seamlessly to other devices.



Cloud computing is much better than accessing multi-device files. Users can monitor their emails on any computer, and even store files using services such as Dropbox and Google Drive thanks to cloud computing services. Cloud computing services also allow users to back-up their music, files, and pictures so that they are available immediately if a hard drive crash occurs.


It offers large companies enormous potential for saving costs. Before the cloud became a viable alternative, companies needed to buy, construct and maintain expensive information management technology. Companies can swap expensive server centers and IT departments for fast Internet connections, where employees interact with the cloud online to complete their tasks.


The cloud system saves computing space on your desktops or laptops. It also helps consumers to update software more easily as software companies may sell their goods through the web rather than via more conventional, tangible methods including disks or hard drives. For instance, Adobe customers can access applications in their Creative Suite through an Internet-based subscription. This helps users to quickly download new versions and update them to their software easily.


Disadvantages of the CloudComputing


Naturally, there are risks involved with all the speed, efficiencies and innovations that cloud computing provides. Security has been a key concern with the cloud, particularly when it comes to sensitive health records and financial details.


While regulations encourage cloud computing services to strengthen their security and risk management measures, it continues to remain an ongoing issue. Encryption protects vital information, but the data will disappear if the encryption key is lost.


Cloud-maintained servers may also suffer from natural disasters, internal bugs, and power outages. A blackout in California could paralyze clients in New York or a Texas firm could lose its information if anything creates its Maine-based supplier to crash.


Conclusion


Cloud computing is a modern technological innovation that has the ability to have a major impact on people's lives. It provides consumers and companies with many advantages. For instance, it lowers operational costs by investing less on maintenance and software updates and tends to focus more on the services it offers to businesses. Yet the cloud infrastructure needs to tackle other obstacles.


People are quite skeptical as to whether their data is safe and protected. There are no global standards or regulations for the provision of data through cloud computing. Europe has data privacy regulations, but the US, as one of the most technically developed countries, has no data protection laws at all. Users are also worried about who could reveal and controls their data. But once global standards and rules are in force, cloud computing will radically transform the world.
