What is Cloud Computing

As more and more people and businesses migrate to cloud services, you might have a few questions about the cloud and why everyone is switching. In this post, we want to help demystify the term by explaining some of the different types of cloud terms you may have heard of (IaaS, PaaS, SaaS, public, private, hybrid) and listing some of the key benefits you or your business can gain from using a cloud service.

  1. Key Benefits of Cloud Computing
  2. Cloud Services
  3. Types of Cloud Deployments

What is Cloud Computing?

The Cloud is Everywhere, All The Time

On a fundamental level, cloud computing is the process of storing and accessing data or programs over the Internet rather than from your computer's hard drive.

Despite the many myths of cloud computing, it's not a complicated or foreign concept. You might even be using cloud computing without realizing it. An online service that receives emails, stores files, or hosts web conference meetings is very likely to be using cloud computing.

Cloud computing can be found in plenty of IT solutions such as storage services, networking, software, analytics, and many more. The possibilities are endless due to the flexibility, scalability, and high availability of Internet-based computing.

Businesses of all sizes are currently using cloud computing to accomplish different objectives, but here are some of the most common cloud applications:

  • Designing and deploying new apps and services
  • Data storage, backup, and recovery with little to no downtime
  • Hosting websites, blogs and other sources of digital content
  • Streaming video and audio, including virtual meeting rooms
  • Delivering software and applications on demand  

Key Benefits of Cloud Computing

Unlike the clunky hardware and complex business IT departments of traditional computing, cloud computing utilizes managed services to increase productivity for a fraction of the cost. More reliable IT resources for businesses of all sizes yield the following key business benefits:

Cost Savings

No need to buy and stack hardware that will depreciate over time and waste electricity for power and cooling. Instead, only pay for the resources you use with your data stored securely in the cloud.

Speed

Just a click away. Enjoy operational flexibility and reduce the time it takes to deploy updates and transfer information (a big bump in team productivity).

Global scale

As a business grows or shrinks, cloud services providers can scale up or down, delivering just the right amount of IT resources needed to maximize efficiency.

Security

Automatic data backup services and disaster recovery options are usually available from most cloud service providers. Look for providers with the latest advanced malware protection, next-gen firewalls, and analytics.

Cloud Services

The cloud is designed to offer you a variety of services to choose from. These are built on top of one another and are called computing stacks:

Infrastructure as a Service (IaaS)

IaaS lets the user rent computing resources, storage, network, operating systems from a cloud provider on a pay-per-use basis. This is the most basic category of cloud services, offering you three main benefits:

  • Little/no hardware investment
  • Scalable infrastructure, better support for dynamic workloads
  • Flexible and highly innovative capabilities available on-demand

Platform as a Service (PaaS)

PaaS provides developers a cloud-based environment/sandbox to develop, test, deliver, and manage software applications. It enhances the development of new apps without worrying about the cost and management of underlying hardware, software, and hosting.

  • Faster time-to-market for new applications
  • Reduced complexity of new deployments
  • Pay only for the resources you need to use

Software as a Service (SaaS)

SaaS allows companies to deliver software-based applications over the Internet, typically on demand and on a subscription basis. In a SaaS model, the cloud provider hosts and manages the underlying infrastructure and handles any maintenance, upgrades, or security patching.

  • Apps and data are accessible from any connected computer
  • All the data is in the cloud, enhances business continuity
  • Fast and secure sign-up

Types of Cloud Deployments

Businesses can choose one package from a variety of cloud deployments that best suits their specific needs. There are three options for deploying a cloud computing solution: public cloud, private cloud, and hybrid cloud.

Public cloud

Public clouds are owned and operated by a third-party cloud services provider. Using the Internet, they deliver computing resources like hardware and software to be used by multiple companies. With public cloud, users don’t need to purchase hardware/software or support/manage their infrastructure. This makes public cloud the most affordable model.

Private cloud

When choosing a private cloud, your organization gets a full stack of resources for your exclusive use. These can be managed and physically located on-premise or at your cloud provider’s datacenter. Some of the key characteristics of a private cloud include:

  • A self-service interface that allows you to quickly provision and allocates IT resources
  • Tailored to specific business requirements with sophisticated security and governance protocols

Hybrid cloud

A hybrid cloud uses a combination of both private and public clouds. This allows data and applications to be be shared between both types of cloud, increasing efficiency and availability. Hybrid clouds let companies keep critical applications and sensitive data in a private cloud, while taking advantage of public cloud resources like the latest applications and elastic virtual resources.
