Cloud Computing

What is Cloud?

Cloud is an online network that allows businesses to share and store data, servers, networks, apps, and development tools. Some of the ways the Cloud is used include online services to send emails, edit documents, watch movies or TV, listen to music, play games, or store pictures and other files. Companies use the Cloud to get new ideas launched, protect their data, and build new products and services. There is not one Cloud or network, and it isn't located in just one place. Rather, the Cloud can be accessed on any device connected to the Internet.

There are several types of Clouds run by different types of providers. Some Clouds are public like when a third party such as Microsoft, AWS, or Google hosts your resources on their servers. Others may be private while some might be shared by a small community. Many businesses use a blend of Cloud environments to limit their risk and increase their capability—we refer to these as hybrid Clouds. When hybrid Cloud users buy services from multiple public Cloud providers, they're using a multi-Cloud approach that lets them operate in the Cloud strategically.

Simply put, Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the Cloud”) to offer faster innovation, flexible resources, and economies of scale. You typically pay only for Cloud services you use, helping you lower your operating costs, run your infrastructure more efficiently, and scale as your business needs change.




Top Benefits of Cloud Computing

  • Cost: Cloud computing eliminates the capital expense of buying hardware and software as well as setting up and running on-site data centers—the racks of servers, the round-the-clock electricity for power and cooling, and the IT experts for managing the infrastructure. All of this adds up fast.

  • Global Scale: The benefits of Cloud computing services include the ability to scale elastically. In Cloud speak, that means delivering the right amount of IT resources—for example, more or less computing power, storage, and bandwidth—right when they’re needed and from the right geographic location.

  • Performance: The biggest Cloud computing services run on a worldwide network of secure data centers, which are regularly upgraded to the latest generation of fast and efficient computing hardware. This offers several benefits over a single corporate data center, including reduced network latency for applications and greater economies of scale.

  • Security: Many Cloud providers offer a broad set of policies, technologies, and controls that strengthen your security posture overall, helping protect your data, apps, and infrastructure from potential threats.

  • Speed: Most Cloud computing services are provided, self-service, and on-demand, so even vast amounts of computing resources can be provisioned in minutes, typically with just a few mouse clicks, thereby giving businesses a lot of flexibility and taking the pressure off capacity planning.

  • Productivity: On-site data centers typically require a lot of “racking and stacking”—hardware setup, software patching, and other time-consuming IT management chores. Cloud computing removes the need for many of these tasks, so IT teams can spend time on achieving more important business goals.

  • Reliably: Cloud computing makes data backup, disaster recovery, and business continuity easier and less expensive because data can be mirrored at multiple redundant sites on the Cloud provider’s network.

Types of Cloud Computing

Not all Clouds are the same and not one type of Cloud computing is right for everyone. Several different models, types, and services have evolved to help offer the right solution for your needs.

First, you need to determine the type of Cloud deployment or Cloud computing architecture on which your Cloud services will be implemented. There are three different ways to deploy Cloud services: on a public Cloud, private Cloud, or hybrid Cloud.

What is Public Cloud?

Public Clouds are owned and operated by third-party Cloud service providers which deliver their computing resources, like servers and storage, over the Internet. Microsoft Azure is an example of a public Cloud. With a public Cloud, all hardware, software, and other supporting infrastructure is owned and managed by the Cloud provider. You access these services and manage your account using a web browser.

What is Private Cloud?

A private Cloud refers to Cloud computing resources used exclusively by a single business or organization. A private Cloud can be physically located within the company’s on-site data center. Some companies also pay third-party service providers to host their private Cloud. A private Cloud is one in which the services and infrastructure are maintained on a private network.

What is Hybrid Cloud?

Hybrid Clouds combine public and private Clouds bound together by technology that allows data and applications to be shared between them. By allowing data and applications to move between private and public Clouds, a hybrid Cloud gives your business greater flexibility, more deployment options, and helps optimize your existing infrastructure, security, and compliance.

Infrastructure as a Service (IaaS)

As the most basic category of Cloud computing services, Infrastructure as a Service (IaaS) allows you to rent IT infrastructure—servers and virtual machines (VMs), storage, networks, and operating systems—from a Cloud provider on a pay-as-you-go basis.

Platform as a Service (PaaS)

Platform as a Service (PaaS) refers to Cloud computing services that supply an on-demand environment for developing, testing, delivering, and managing software applications. PaaS is designed to make it easier for developers to quickly create web or mobile apps without worrying about setting up or managing the underlying infrastructure of servers, storage, network, and databases needed for development.

Software as a Service (SaaS)

Software as a Service (SaaS) is a method for delivering software applications over the Internet on demand and typically on a subscription basis. With SaaS, Cloud providers host and manage the software application and underlying infrastructure and also handle any maintenance like software upgrades and security patching. Users connect to the application over the Internet typically through a web browser on their phone, tablet, or PC.

Serverless Computing

Overlapping with PaaS, serverless computing focuses on building app functionality without spending time continually managing the servers and infrastructure required to do so. The Cloud provider handles the setup, capacity planning, and server management for you. Serverless architectures are highly scalable and event-driven, only using resources when a specific function or trigger occurs.

Uses of Cloud Computing

You’re probably using Cloud computing right now, even if you don’t realize it. If you use an online service to send emails, edit documents, watch movies or TV, listen to music, play games, or store pictures and other files, it’s likely that Cloud computing is making it all possible behind the scenes.

The first Cloud computing services are barely a decade old, but already a variety of organizations—from tiny startups and global corporations to government agencies and non-profits—are embracing the technology for all sorts of beneficial reasons.
