What are Infrastructure, Software, and Platform in cloud computing
What are some cloud computing examples?
While cloud computing can take many forms, the majority falls into three key areas. Each type of cloud computing provides its own set of advantages.
Software as a Service (SaaS)
Traditionally, software was installed directly on each individual device. With the software as a service (SaaS) computing model, web applications are hosted in the cloud to reduce costs through pay-as-you-go pricing. End users can easily connect to the cloud application through a web browser or mobile device, and there’s no need for IT departments to get involved with management or maintenance. Examples include Gmail, Salesforce CRM, and RightSignature, as well as cloud storage services like OneDrive and Dropbox.
Infrastructure as a Service (IaaS)
The infrastructure as a service (IaaS) computing model moves an organization's entire data center to the cloud. The business rents virtual machines (VMs), virtual servers, operating systems, and other IT infrastructure on a pay-as-you-go basis. The cloud service provider is responsible for maintaining all data storage servers and networking hardware, eliminating the need for a resource-intensive, on-site installation. Examples include Microsoft Azure, Google Cloud, Oracle Cloud, and Amazon Web Services (AWS).
Platform as a Service (PaaS)
The platform as a service computing model gives organizations the power to develop software without needing to maintain the backend environment. PaaS vendors optimize environments for each tenant's unique needs, and often include supplemental development tools such as storage resources, compile services, and version control.
Is cloud computing secure?
Cloud providers take cloud security very seriously. Vendors have developed complex security protocols based on encryption and authentication, and take steps to ensure tenants can’t access their neighbor's data.
In general, servers are regulated by the laws of the country they reside in. That means data stored on a European server will be regulated differently than a server in the U.S. Organizations that handle private user data need to be aware of all regulations that may apply to their cloud solutions.
