More and more, we are seeing technologies, which are moving to the cloud. But what does it mean?
Cloud computing is a big shift from traditional software models to the Internet has gradually gained momentum over the last 10 years. Furthermore, the next decade of cloud computing promises new ways to cooperate everywhere, through mobile devices.
In this article, we are going to explain the concept “what is cloud computing?” as well as “How cloud computing works?”
The history of cloud computing
It was the year of 1991, when Salesforce introduced its first commercially successful implementations of enterprise SaaS. At that time, World Wide Web has born and computing service became practical.
In 2002, this was followed closely by the arrival of AWS, which offered range of services, including computation and storage – and now machine learning, embracing databases and other services.
Nowadays Google Cloud Platform, Microsoft Azure and other providers have joined AWS in providing cloud-based services to individuals, small corporations or businesses and global enterprises.
What is cloud computing?
Cloud computing is simply storing data, accessing data and programs over the Internet instead of your computer’s hard drive. The cloud is just a metaphor for the Internet.
The technology accesses and uses of multiple server-based computational resources through a WAN (digital network), internet connection using the world-wide-web etc. Cloud users are able to access the server resources using a computer, smart phone, netbook, pad computer and many other devices.
Moreover, in this, remotely stored cloud server and data of cloud configuration provide and manage applications. Users do not download and install applications on their own computer or other device.
In fact, all processing and storage is maintained by the cloud servers only. A private organization or a cloud provider may offer such on-line services.
How cloud computing works?
Cloud computing technology services all work a little differently, that depends on the provider. But, many provide neighbourly, browser-based dashboard that makes it easier for IT professionals and developers to order resources and maintain their accounts.
While, some of the cloud computing technology services are designed to work with a CLI (command-line interface), and REST APIs, which offers multiple options to developers.
Cloud computing Uses
You are almost using cloud computing right now, even if you don’t realise it. If you are using an online service, it is likely that cloud computing is making it all possible behind the scenes. So, here is the list of things that you can do with the cloud:
- Store, back up and recover data
- Create new apps and services
- Host websites and blogs
- Deliver software on demand
- Stream audio and video
- Analyze data for patterns and make predictions
Benefits of cloud computing technology
Why is cloud computing so popular? What is it about cloud computing? Here are some common reasons, why organizations are turning to cloud computing services:
The cloud computing is mainly enables virtualization technology. So that performing computing tasks becomes easy to use and manage. By minimizing user involvement, it provides automation speeds up the process, reduces the possibility of human errors, giving businesses a lot of flexibility and taking the pressure off capacity planning.
Cloud technology helps to reduce cost with completely remove the capital expense of buying hardware and software. Though, with better cost savings ability, it can also setting up and running on-site datacenters – the round-the-clock electricity for power and cooling, the racks of servers, the IT experts for managing the infrastructure. It adds up fast.
3. Global scale
The main benefit of cloud computing services is the ability to scale elastically. It helps to deliver the right amount of IT resources. For example, more or less computing power, bandwidth, storage- right when it needed and from the right geographic location.
The largest cloud computing services are run on a worldwide (Global) network of secure data centers, which are regularly upgraded to the newest generation of efficient and fast computing hardware. Which in turn, provides several benefits over a single corporate datacenter, including greater economies of scale and reduced network latency for applications.
The Cloud technology gives guarantee a more secure environment, thanks to its greater resources to security and centralization of data.
It removes the need for many of these tasks, such as on-site datacenters typically require a lot of “stacking and racking”- hardware set up, software patching and other time-consuming IT management chores. So that, IT teams can spent time on achieving more important business goals.
Additionally, this methodology can make disaster recovery, data backup and business continuity easier and less expensive. The reason is- the mirror data can be created at multiple redundant sites on the cloud provider’s network.
Types of cloud services: IaaS, PaaS, SaaS
The types of cloud computing services are fall into 3 categories: first is infrastructure as a service (IaaS), second is platform as a service (PaaS) and third is software as a service (Saas). These types of services are sometimes called the cloud computing stack, because they build on top of one another.
Cloud is nothing but the most advance model of computing with three basic models, also knowing how they are and what they are different makes it easier to accomplish your business goals.
Infrastructure as a service (IaaS)
The most basic category of cloud computing services with IaaS is- IT infrastructure- IaaS is nothing but a model in which the cloud consumer outsources responsibility for their infrastructure to an external cloud provider.
However, this cloud provider not only owns the equipment that offers the infrastructure resources but is also responsible for the maintenance of ongoing operations. The third party hosts elements of infrastructure like servers and virtual machines (VMs), networks, storage, operating systems—from a cloud provider on a pay-as-you-go basis.
Platform as a service (PaaS)
PaaS refers to cloud computing services that allows users to test, deliver, develop and manage software applications. PaaS is designed to make it easier for developers to quickly create mobile apps, and web pages without worrying about managing or setting up the underlying infrastructure of servers, network, storage and databases needed for development.
Software as a service (SaaS)
The term SaaS refers to cloud computing services that gives method to deliver software applications over the Internet, on demand as well as typically on a subscription basis.
With Software as a service, cloud supplier can host and manage the software application, underlying infrastructure and handle any maintenance, like security patching and software upgrades. Users connect to the application over the Internet, generally with a web browser on their phone, PC or tablet.
Types of cloud deployments
There are 3 different ways to deploy cloud computing resources: public cloud, private cloud and hybrid cloud.
Public clouds are owned and managed by a third-party cloud service provider, which deliver their computing resources such as storage and servers over the Internet. Microsoft Azure is a best example of a public cloud. With a public cloud, all software and hardware and other supporting infrastructure is owned and operated by the cloud provider. User can access these services and operate his account using a web browser.
Only a single organization or single business use a private cloud. This private cloud can be physically situated on the company’s on-site datacenter. Moreover, a private cloud is one in which the infrastructure and services are operated on a private network. Some companies also pay third-party service providers to host their private cloud.
Hybrid cloud, on the other hand, refers to cloud computing resources combine public and private clouds, bound together by technology that enables data and applications to be shared between them. By allowing data and applications to move between public and private clouds, hybrid cloud provides businesses greater flexibility and more deployment options.
Certainly, we are going on the right track as far as improving its digital infrastructure is concerned. At Do SpeedTest, we are proud to be a part of the change by offering you the best internet speed test, broadband speed test, DSL speed test and bandwidth test on the Web.
