The end-user pays for a license in order to access and use the software, but the software itself is hosted on the provider's systems in the cloud infrastructure. These three layers, IaaS, PaaS, and SaaS, are sometimes called the cloud computing "stack" because they build on each other: PaaS contains IaaS, and SaaS contains all three. The idea is to allow end-users to pay for only as much as they need when they need it. What Are The Advantages Of Cloud Computing? In addition to the overall cost-efficiency for the end-user, using cloud infrastructure has a number of key advantages: Flexibility: Users aren't limited to a single device or a single location. With the right security measures in place, anything that's in the cloud can be accessed anywhere there's an active internet connection. Data storage and backup: Information that is kept in any type of cloud storage is insulated from data loss or destruction of a business's physical location. On the provider side, data is fragmented across multiple locations to limit the risk of data loss.

This middle layer is where IaaS providers and software developers overlap. Examples of PaaS providers: Oracle Cloud, Salesforce Platform, Google Cloud Platform, Amazon Web Services SaaS (software as a service) is the topmost and more familiar layer of the cloud stack. This is where applications and software are, and we see some familiar names like Spotify, Adobe Creative Cloud, Google Play Store, Storj, and Dropbox to name a few. The SaaS layer is essentially where cloud services become user-friendly for consumers and businesses alike. Examples of SaaS providers: Slack, WordPress, Trello, Mailchimp, InVision, Zoom, Buffer, Contently, Netflix The basic cloud computing stack Each layer of the cloud service stack enables the one before it. In short, you can think of the three layers like this: first, you need hardware. Second, you need a platform to build from. Third, you need applications so people can use the hardware. The Pros and Cons of Cloud Computing While each use case will have much more granular pros and cons, the following are a few general benefits and drawbacks of cloud computing.

Basics of Cloud Computing

But as the AI learns this, it can impart this new data back to the cloud, which can thus help other AIs learn as well" as noticed Gary Eastwood from the IDG Contributor Network. Same goes for blockchain and other data intensive technology. Cloud computing is not only the digitization tool par excellence, it is omnipresent and plays undoubtedly a key role in today's technological progress. Providing IT resources and on-demand applications over the Internet at usage-based prices "Simply put, cloud computing is the delivery of computing services — servers, storage, databases, networking, software, analytics and more — over the Internet ("the cloud"). Companies offering these computing services are called cloud providers and typically charge for cloud computing services based on usage, similar to how you are billed for water or electricity at home. " (Microsoft Azure) Whether you run apps that share photos with millions of mobile users or support critical business operations in your organization, the cloud is a technology providing quick access to flexible and cost-effective IT resources.

In simple terms, cloud computing is the on-demand delivery of IT resources and applications via the internet with pay-as-you-go pricing. The cloud offers an easy, flexible and low-cost way to access servers, storage, databases, and a vast array of application services for organisations ranging from those running consumer-facing mobile applications for millions of users, to the worlds largest financial institutions who need to support the critical operations of their business while complying with diverse global regulations — all while providing an exceptional user experience for their customers. There is no need to make large upfront investments in hardware or spend a lot of time managing that hardware with cloud computing. With cloud computing, you can provision exactly the right type, size and amount of computing resources you need almost instantly, and pay only for what you use. Organisations can optimise their spending as they can reconfigure the computing environment quickly to adapt to changing business requirements.

Cloud providers ensure some sort of separation for resources used by different organizations. This is known as multitenancy. Private cloud. This is where cloud infrastructure is solely owned by an organization and maintained either by this organization or a third party and can be located on site or off-site. Computing resources are behind the corporate firewall. Community cloud. Here, cloud infrastructure is owned and shared by multiple organizations with a shared concern. Hybrid cloud. It is the combination of any type of cloud model mentioned above connected by standardized or proprietary technology. (Related: What is hybrid cloud? ) Companies stopped generating their own electricity using steam engines and dynamos as the electric grid provided a better means of getting electricity. Similarly, organizations these days can rely on the cloud service providers to get computing resources on-demand and in an automated fashion. Organizations only pay for the resources they have used and relinquish unnecessary resources using a self-service portal.

Wireless connectivity with almost the same speed is not possible. You do not need to drag a cable around, you just have a decent internet connection. Because of the increasing capability of the internet, developers have looked beyond information sharing. Certain functions in desktop could now be done online. Office documents could be uploaded and extracted or even worked on at the same time online. Data processing is not limited anymore to your desktop as the increasing capacity of online connectivity has made it possible to emulate or even surpass local data processing. Cloud Computing is Born In gist, cloud computing is all about implementing process online instead in your local gadget. Data and processes could be done online without the need of any local software or client. As long as the user knows the process and have the right security credentials, he could access the system and make the necessary changes. Cloud Computing Advantages There are many advantages a company would have if they would consider cloud computing as part of their business plan.

Summa summarum, the cloud's success is nowadays more and more influenced on the macro level for example with GDPR and CLOUD Act. Governments, regulators, policymakers and standards setting organizations have a big influence especially on standards for cyber security at the micro-level. For the cloud, this means more regulation but also more adoption opportunities through new customers who had data privacy concerns towards cloud based solutions. In other words, there is no end to the cloud's explosive growth. What about a new way of innovative differentiation? Nowadays we notice more and more a change in cloud competition. Microsoft Azure has surpassed Amazon AWS in terms of annual revenues. The cloud industry with its huge potential seems to undergo a change in competition which can be explained by a few notable trends that are emerging: The few giants that make up the cloud industry form the top-tier cloud providers while a number of smaller and niche players occupy 35% of the market.

In either case, cloud computing is actually a stack of three generalized cloud provided services. At the base of the stack is the infrastructure cloud services also known as infrastructure as a service (IaaS). The middle layer is the developer's layer known as platform as a service (PaaS). The top and the most visible layer is the software as a service (SaaS) layer also known as the application layer. IaaS (infrastructure as a service) is the foundational layer made up of all the necessary hardware that makes the digital cloud tick. Despite the reference to watery vapor above us, cloud computing is made of some serious hardware, real, tangible, and often loud. IaaS is all of the physical hardware that stores and moves our zeros and ones. Examples of IaaS providers: CloudSigma, Digital Ocean, Linode, Cisco Cloud Infrastructure Services, Microsoft Azure, Citrix Workspace Cloud PaaS (platform as a service) is the next layer up, where the developers and programmers get involved. In this middle layer, IaaS providers lease chunks of cloud hardware to developers and programmers pre-installed with developer tools like Apache or MySQL.

The biggest of them all is security. Since cloud computing uses the power of online connectivity to handle processing requests, the data could be available for everyone and could be used for malicious purposes. There is also the challenge of the end-user connectivity. Cloud computing will only be possible if there is a strong internet connection. Cloud computing might not work in areas where internet connection is weak. Although there are applications that might be work with simple dial-up connectivity, the application could easily go down especially when there is too many data to be processed. Infrastructure is also a challenge for cloud computing. A company who opts to have their own server would have to ensure the infrastructure will be able to deal with consistent and massive data and processing requests. But even with these challenges, cloud computing is seen as one of the futures of the internet. It is changing the way businesses complete their transactions and it will certainly make some changes the way people look at the internet.
