What Is Cloud Computing?

which often use these platforms to develop their services, and PaaS also allow third parties to

Some of the immediate advantages of cloud computing involve lower equipment costs, scalability and online collaboration. A company can take advantage of cloud services without major upgrades to their existing equipment and infrastructure. Using a web browser, most company employees can access “Software as a Service” or SaaS. This service runs on a cloud provider’s server with no installed on the local server within the organization.

PaaS is the second type of the service layer of cloud computing. PaaS provides a platform and environment as a service over the Internet which is usually targeted to developers. The purpose of Paas is to allow the developers to build an application and services over the Internet. PaaS services normally are treat in the cloud which it can be accessed by users simply via their web browser. In order for these application to run smoothly, there needs to be platform supporting it just as powerful and flexible. Besides that, Platform as a Service also allows users to create their own software applications using tools that supplied by the cloud provider. PaaS Services consist of preconfigured features that customers can subscribe. Besides that, to subscription basis in PaaS services, users need to pay for it so that it will be works. According to (Wang, GE, PING, WU & FU, 2010), an examples of well-known PaaS is Google App Engine. Google App Engine offers the circumstance to creating Java and Phyton on the servers that hosted by Google.

At a minimum, IaaS public cloud services offer storage and compute services on a pay-per-use model. But the full array of public cloud providers services offered by all major is mind blowing. Virtual private networks, Highly scalable databases, big data analytics, machine learning , developer tools, application monitoring etc. Amazon Web Services was the first IaaS provider, followed by Microsoft Azure, Google Cloud Platform and IBM Cloud.

“IaaS essentially refers to purchasing the basic storage, processing power and networking to support the delivery of cloud computing applications. It's a logical next step for organizations that want to move specific processes and applications into the cloud, but that still want to maintain a large degree of control and administration over the functions and applications themselves” (Akamai Technologies ).

Infrastructure as a Service(IaaS) is a technique for passing on Cloud Computing establishment servers, storing, mastermind and working systems as an on asking for advantage. Instead of getting servers, programming, datacenter space or framework adapt, clients rather buy those advantages as a totally outsourced advantage on ask.

Infrastructure as a service (IaaS) and platform as a service (PaaS) are two cloud service options that allow you to hang on to your legacy applications. IaaS provides an environment for hosting the application along with infrastructure security. Your business is still responsible for controlling access to the application. With PaaS, the cloud provider patches the operating system and the platform but is not responsible for access management or patching of the application itself.

The cloud removes the need for you to be in the same physical location as the hardware that stores your data. There are number of functionally equivalent services in the cloud Due to unreliable internet connections different cloud applications may receive different levels of quality for same cloud services so that optimal service selection becomes important. Cloud computing provides three main services, namely Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). In Software as a Service (SaaS), Clients can use the software that is provided by the provider, which usually need not to be installed on their own machine and they can use the software

There are a variety of definitions that are associated with cloud computing. However, the importance of how the technology is transforming business models greatly exceeds any specific definition. There are three components that are usually cited in any definition of cloud computing (Gabrielsson, Hubertsson, Mas, & Skog, 2010). The most commonly known component is the Software as a Service (SaaS). This allows organizations and consumers the ability to use software on demand and be billed for the usage on a per use basis.

These private environments are made accessible via the Internet. Cloud computing provides services such as software (applications), platforms and infrastructures with a subscription-based in a pay-as-you-go model. These services are generally referred as Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).

There is wide range of services that could be provided by cloud providers. Based on blabla, there are 3 models of cloud services that widely popular. They are Infratructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides for fundamental resource for computing such as processing, servers, storage, networks and manage its physical infrastructures but costumers have control for their OS [fn1]. PaaS provides design, tools or Environment with IDE. It is usually used by software developer who wants to run their application over internet. SaaS delivers ready-use software over internet or we can called as web-based software. Cloud users neither have to maintain platform or infrastructures. These days this services gain money from advertising or user list sales for example Google mail service so users can enjoy it free.

PaaS is a platform level cloud service that provide an operating system, database and web server, in which the developers build the applications using different software development tools and to run on a cloud platform. The example of this service can be seen on Google App Engine hosted by Google. Once the user login to his/her account, he/she able to develop

Infrastructure as a Service (IaaS) is a cloud model which allows organizations to outsource computing equipment and resources such as servers, storage, networking as well as services, such as load balancing and content delivery networks. The IaaS provider owns and maintains the equipment while the organization rents out

As information technology continues to improve, applications no longer are limited to being installed locally on a physical computer or server. Cloud computing now allows applications be access via a virtual solution knows as the "cloud". There are many essential characteristics of cloud computing such as on-demand access, pay per use, connectivity, and resource pooling (Durkee, 2010). Users must be able to trust the connectivity when relying on access an application over the internet. Today 's cloud servers are connected to high-speed networks that allow data to flow to the Internet. These high-speed networks improve reliability and expand accessibility. Cloud computing offers

Cloud computing enables businesses to deploy or subscribe to services as it needs them. A cloud features self-service, broad network access, centralized shared resources, and measurement of service usage. There are three widely accepted types of cloud service models. They are Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Each serves a different purpose and business may choose to use just one, two, or even all three of the cloud types simultaneously as the needed.
