CONTACT USCloud Computing is the delivery of IT resources and computing services over the internet and on a pay-as-you-go basis. Instead of buying and maintaining IT infrastructures like servers, storage, databases, software, analytics tools, and applications, you can access them on an as-needed basis from cloud providers. This way, you pay only for cloud services and technologies you use. In turn, you save money on buying or hiring equipment, training IT staff, and maintaining an in-house infrastructure.
Organizations of all shapes and sizes use cloud computing to reduce operating costs, benefit from economies of scale, innovate faster, and increase security and compliance. The users of cloud services can be categorized into three, namely:
• Private companies
Large corporations, small businesses, and startups worldwide use cloud computing to provide services to their customers. For example, Netflix uses cloud computing to offer entertainment services to their customers, healthcare companies use it to personalize patient treatment, and financial services providers like banks leverage the power of the cloud to prevent and detect fraud.
• Government organizations
More and more federal, state, and local government agencies are moving their systems, data, and solutions to the cloud. They use cloud computing to reduce cost, simplify collaboration within and between agencies, manage assets, detect fraud, improve operational efficiency, and more.
• Individuals
We all utilize cloud services when accessing the internet and using services like email, social media, online banking, or more. Many of us even store photos, messages, and personal information by utilizing cloud storage services.
There are three main ways to deploy cloud services. They can be deployed on a public cloud, private cloud, or hybrid cloud.
• Public Cloud
Public clouds are owned by third-party cloud service providers who manage the hardware, software, and supporting infrastructure. You can assess a public cloud and manage your account through a web browser. The main public cloud providers are Amazon (Amazon Web Services), Microsoft (Azure), and Google (Google Cloud Platform). Other providers include IBM and Oracle.
• Private Cloud
Private clouds refer to cloud computing resources that are reserved exclusively for the use of one business or organization. A private cloud may be hosted by a company’s on-site data center or by a third party.
• Hybrid Cloud
A hybrid cloud refers to the combination of private and public clouds. Here, data and applications are shared between both clouds, giving users more flexibility and deployment options.
Cloud computing services can be categorized into infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Services (SaaS), and Function as a Service (FaaS). Let’s delve further to help you understand what these services are and how they are different from one another.
• Infrastructure as a Service (IaaS)
IaaS providers rent servers, storage, and virtual machines to customers on a pay-as-you-go basis. IaaS is the most basic category of cloud computing services, and it gives you the maximum level of control over your IT resources.
• Platform as a Service (PaaS)
In this model, the provider hosts application development platforms and tools on its infrastructure and makes them available to the customers over the internet. With PaaS, developers can create apps without worrying about setting up the underlying infrastructure needed for development.
• Software as a Service (SaaS)
SaaS is a software distribution model in which the provider hosts applications and makes them available to customers over the internet on a subscription basis. The provider also manages the software and handles maintenance like upgrades and security patching.
• Function as a Service (FaaS)
Here, the provider hosts applications and functions without spending time continually on managing the underlying infrastructure. FaaS is also known as Serverless Architecture.
• Cost savings
Cloud computing helps you avoid the massive amount required to purchase, set up, and maintain hardware and software. You also won’t have to spend money on facilities to accommodate hardware or to build large data centers. Additionally, cloud computing eliminates the need for a large IT team to manage your cloud data center operations, thereby helping you save some personnel costs.
• Increases speed to market
Cloud computing increases your organization’s agility, flexibility, and speed to market by giving you access to a wide range of technologies and computer resources. What’s more, whatever you need, can be provisioned in a matter of minutes. This way, you can test new ideas and innovate faster than ever before.
• Mobility
Migrating your systems and information to the cloud means you will be able to access it at any time and from anywhere with any device that has an internet connection. This eliminates the need to carry around external hard drives or USB drives to access the information you need. In addition,
you won’t have to worry about any upgrades as they will be done automatically by your cloud provider.
• Productivity
Cloud computing eliminates the need to spend time on setting up on-site data centers and other hardware, thereby helping you channel your time and energy on those things that matter to your business.
• Elasticity
Cloud computing helps your organization scale without hassle. It allows you to provision the number of resources you need at any particular point in time. In other words, cloud computing enables you to easily scale resources up or down as your business needs change.
• Data recovery
Storing your data in the cloud means your organization would no longer have to worry about data loss. With cloud computing, you would still be able to access your data even when your devices are inoperable.
• Security
Most cloud providers offer technologies and controls to help you strengthen your overall security posture and protect your data and infrastructure from threats.
