Although most people do not think about it, they probably use cloud computing every day. Anyone who uses an online service to send an email, edit documents, play games, store pictures, watch movies and TV, or listen to music utilizes the cloud. The first cloud computing services are a decade or so old, and companies from tiny startups to global corporations. Then there are government agencies to non-profits that embracing the technology for a variety of different reasons including; Creating new apps and services, storing, backing up, and recovering data, hosting websites and blogs, streaming audio and video, delivering software on demand and analyzing data for patterns and making predictions. Before making a move to the cloud, companies should understand how cloud computing works, what benefits it can deliver, and the costs to run in the cloud.
What Is Cloud Computing?
Cloud computing services all work a little differently, depending on who the provider is. Most provide a user-friendly, browser-based dashboard that makes it easy for IT professionals and developers to order resources and manage their accounts. Some cloud computing services are also designed to work with REST APIs and a command-line interface (CLI), giving developers multiple options. Cloud computing is an arrangement between a provider and a customer that allows the customer access to a server that remains under the control of the provider. Usually, there is a recurring or monthly fee for these services. The customer can use the server in various ways, including as hardware on which programs run, or to store data. Using a server in this way is often referred to as IaaS. Others use the server as a platform on which to develop their software (PaaS), and others use the server as a portal that accesses a service such as a payment portal for a customer or to process the customer’s data (SaaS).
Benefits of Cloud Computing
Cloud computing can significantly reduce the investments an enterprise needs to make in hardware and software and eliminate the need for on-site data centers and IT staff to manage the infrastructure, reducing utility, labor, and overhead costs.
Cloud computing eliminates the need for ongoing IT tasks such as “racking and stacking,” setting up hardware and patching software. It makes your organization more productive and enables your IT personnel to focus on more important business goals.
Cloud computing can provide an enterprise elastic scalability to meet the ever-changing IT requirements of your enterprise. You will always have the right amount of IT resources available for storage, computing power, and bandwidth, whether your business is seasonal or steady.
The most crucial cloud computing services run on a global network of secure data centers. Also, they are regularly upgraded to the latest generation of the fastest and most efficient computing hardware. This would mean improved performance, reduced latency, and the benefit of economies of scale.
Cloud computing makes business continuity and disaster recovery more accessible and less costly because data is mirrored at multiple redundant sites on the cloud provider’s global network.
Since cloud computing services are self-serve and on-demand, you can provide vast computing resources on the fly-in minutes — no more worries over capacity planning.
Cloud Computing Deployments
Cloud computing can be deployed in different ways. It is crucial to understand how the different deployments work to choose the right type or combination of cloud deployments that best fit your organizational needs.
Cloud Types
Cloud computing services are defined by three categories: IaaS-The rental of IT infrastructure that includes servers, virtual machines, networks, operating systems, and data storage from a cloud provider on a pay as you go basis.
PaaS– This includes cloud computing services that provide an on-demand environment that developers can utilize to develop, test, deliver, and manage software applications.
SaaS is cloud computing that provides a way to deliver software applications over the internet on-demand. Typically these cloud services are on a subscription basis. The cloud provider hosts and manages the software application and the underlying infrastructure, including maintenance, upgrades, and software patches. Users connect to the demand over the internet using a browser.
Public Cloud
A cloud owned and operated by a third-party provider. Computing resources, including servers and storage, are delivered over the internet. All of the system components, such as hardware, software, and any other supporting infrastructure, are owned and managed by the third-party cloud provider.
Private Cloud
Cloud resources that a single business or organization uses exclusively. The cloud can be physically located on a company’s on-site data center or hosted by a third-party provider. The services and infrastructure are maintained on a private network.
Hybrid Cloud
A hybrid cloud combines public and private clouds. The clouds are bound together by technology that allows data and applications to be shared. A hybrid cloud usually involves a firewall to enhance data security and applications moving between the two clouds. For many businesses, this is the best choice because the private cloud better protects sensitive data, and it offers greater flexibility and more deployment options.
