What is Cloud Computing?

Cloud Computing refers to the running of workloads across the internet remotely. This is provided by a public cloud with popular systems including Amazon Web Services, Google Cloud, and Microsoft Azure. In this article, we outline the main types of cloud computing and the benefits of the cloud for your business.

Types of Cloud Computing

There are three main types of cloud computing.

Public Cloud

Public clouds let customers gain vital new capabilities without the need to invest in expensive hardware or software. Instead, they pay a yearly or monthly subscription fee or simply pay for what they need. In no time at all, users can set up accounts and get started. When needed, more users and resources can be added easily thanks to auto scaling.

Private Cloud

Private clouds are computing resources used by one company or organisation. These systems can be physically located on-site in a data centre or can be supplied externally by third-party services. This cloud infrastructure is maintained on the private network alone.

Hybrid Cloud

Hybrid clouds bridge on premise and cloud in order to allow data and applications to be passed between them. Doing so gives businesses more flexibility, more deployment options and helps in optimising your infrastructure, compliance and security.

Types of Cloud Computing Services

There are three main categories of cloud computing services that you will come across.

Infrastructure as a Service (IaaS)

On a basic level, IaaS public clouds give users cloud storage and computing services on a pay-per-use basis. However, on a more extensive level IaaS services can include scalable databases, VPNs (virtual private networks), developer tools, big data analytics, application monitoring, machine learning and more. Notable IaaS services are Amazon Web Services, Microsoft Azure, Google Cloud Platform and IBM.

Platform as a Service (PaaS)

Platform as a service refers to cloud computing services that provide an environment for developing, testing, and delivering software applications. Every PaaS is designed to make it simpler for developers to create and release web and mobile applications. With SaaS, developers also don’t have to worry about managing the services, storage and network required to launch apps.

Software as a Service (SaaS)

Typically delivered through a web browser, Software as a Service applications are one of the most common cloud computing services available. The most used examples include Microsoft Office 365, Google’s G Suite and Salesforce. Most enterprise applications adopt this model and feature extensive configurations options to tailor the service to their needs.

Benefits of Cloud Computing

Cloud computing has transformed how businesses approach their IT resources. There are various benefits of cloud computing, making it the ideal choice for many businesses.

Cost

Cloud computing removes the need to spend on buying expensive hardware and software, setting it up and running your own data centres. The price of managing servers and hiring IT professionals to handle it racks up very quickly.

Speed

Most cloud computing services are self service in an on demand model, so even a huge amount of computing resources can be gained in minutes, usually with a few clicks. This gives every business a lot of flexibility and takes the pressure off planning capacity.

Scalability

Cloud computing services offer the ability to scale when needed. In cloud terms, this means delivering the right amount of IT resources at the right time in the right place.

Productivity

Data centres typically require a lot of resource spent on hardware setup, software patching and other time-consuming IT management chores. With cloud computing, these tasks are done by the provider rather than the customer, so IT teams can adopt a more agile approach and spend time on achieving more important business goals. Resources can be switched on and off as required, with a greater focus on consumption rather than installation.

Reliability

Cloud computing makes vital tasks much easier, including backup, business continuity, and disaster recovery. This is because data can be mirrored at multiple redundant sites on the network of the cloud provider.

Security

Many cloud providers offer a set of policies, technologies, and controls that improve your overall security posture, protecting your data and proving compliance with industry regulations.
