Cloud computing allows you to move the heavy lifting and crunching of data off your device to huge computer clusters located in cyberspace. It is possible to access these massive computers via the Internet. This allows you to access your files, applications, and development tools from any location. This allows you to work more efficiently on your laptop on an overcrowded train or on your mobile at a conference table.
The cloud also makes sure that your work remains accessible even if the office goes out of power. This is because it has a backup of all your data and applications. Some of the biggest companies worldwide have migrated to the cloud, and have tested its security and performance.
There are several different types of cloud service and deployment models. They are typically categorized into four service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS) and Serverless/Function-as-a-Service (FaaS). The terms “cloud” and “cloud computing” are sometimes used interchangeably, however it is crucial to know the difference between IaaS and PaaS and FaaS, so that you can determine which of these cloud deployment models will best meet your requirements.
IaaS is an online service that lets you rent a full stack of hardware, including servers, firewalls and virtual machines through a cloud provider. This is a great choice for companies who create special-purpose or proprietary applications that need servers to be maintained and controlled, but do not wish to invest time or money purchasing, storing and establishing their equipment.
