Cloud is one of the most talked-about technologies in the enterprise world these days. That’s true but it’s even more than that. Presently, the cloud is among the most rapidly adopted technologies as well. More and more corporates are either partially adopting or fully migrating their IT infrastructure to cloud computing platforms. Let’s see what’s cloud computing and what are the different types of cloud platforms.
What Is a Cloud (In Terms of Computing)?
A cloud is a computing model where users access computing services on remote servers over the internet. The services may include but are not limited to computing, processing, application, storage, and content. Cloud is not meant to be a single physical entity but an ecosystem. The ecosystem involves a vast network of servers at different locations around the globe connected to make a virtual entity. The servers we are referring to are configured to manage and store data, run applications, deliver content like audio, video streaming, provide services such as office productivity, webmail, or database. The users don’t have to access applications, files, and data from a personal computer or on-premises servers, rather they are accessing them through the Internet. These services can be made available wherever and whenever they want.
Types Of Cloud
Classification of clouds can be done in two ways.
• By Deployment
• By Service
By deployment, the cloud can be classified into three major categories:
A public cloud is where the cloud services are delivered over the public network. In this model, on-demand services are subscribed from shared resources (servers).
A private cloud is a dedicated cloud infrastructure meant for an organization and delivered on a private network.
The hybrid cloud shares characteristics of both public and private clouds. In this model, some of the features like storage and the database may remain within the private cloud and some of the applications may be accessed over the public cloud.
There are various types of cloud by service, major categories are as follows:
SaaS – Software as a Service
In this computing model, instead of installing an application or software on a local computer or server, the user access and execute the application or remote server over the cloud.
Examples of SaaS:
Google Workspace, Dropbox, Salesforce, MailChimp, Cisco WebEx, SAP Concur, GoToMeeting
PaaS – Platform as a Service
In this cloud model, the user acquires the whole platform like Infrastructure, OS, and development tools to build their applications
Examples of PaaS: Microsoft Azure, Heroku, Force.com, AWS Elastic Beanstalk, Google App Engine, OpenShift.
IaaS – Infrastructure as a Service
In this type of cloud, the user only acquires the infrastructure and uses it on their own. It’s like leasing the hardware like servers, storage, and networking.
Examples of IaaS: Amazon Web Services (AWS), Google Compute Engine (GCE), Microsoft Azure, Cisco Metacloud, Rackspace
FaaS – Function as a Service
In this type of cloud, the user can get a code triggered in the response of some action or remote procedure call. In this type of cloud, infrastructure is used only for that instance.
Examples of FaaS:
IBM Cloud Functions, Amazon’s AWS Lambda, Google Cloud Functions, Microsoft Azure Functions (open source), OpenFaaS (open source)
CaaS – Container as a Service
In this type of cloud, the user can deploy and manage apps using container-based abstraction
Examples of CaaS: Google Kubernetes, Docker Swarm, AWS (ECS), Azure (ACS), Pivotal (PKS)
