Cloud computing
- 3. Cloud computing is providing different facilities and amenities like databases, servers, storage, applications, etc., through the Internet. Instead of storing data in local storage on a hard drive, cloud computing helps us in storing and saving data on a remote database. Given that the device we are using has access to the internet, it will have access to the data as well.
- 5. Cloud computing is so named because the information and data that we are trying to access are discovered remotely in the cloud, which is nothing but virtual space. Users can store files, data, and applications on remote servers and access this data with the help of the Internet.
- 6. We have various functions that can be achieved with the help of cloud computing services, like: Email Storage, backup, and data recovery Scrutinizing data Building and testing apps Providing software on demand Audio and video streaming Working of cloud computing
- 8. It is easy for users to come up with resources on demand for nearly any type of application functionality; hence there is no need for IT administrators to provide resources. Organizations can scale up as requirements rise and scale down as requirements fall. This reduces the investment cost in infrastructure. It allows users to pay merely for the resources and infrastructure they are using.
- 10. There are three kinds of cloud deployments or cloud computing architecture to choose from for implementing our cloud services. We could deploy these services on public, private or a hybrid cloud.
- 11. Public clouds are owned and maintained by third-party providers of cloud service that offer their resources like servers, databases, and storage over the Internet. Microsoft Azure and Salesforce are examples of public clouds. By means of a public cloud, all the infrastructure is managed by the third- party cloud provider.
- 12. A private cloud suggests that cloud computing resources are being used entirely by a single entity, either a business or an organization. Physically, a private cloud is usually located on the company site. The network used in a private cloud is a private network that is responsible for its services and infrastructure.
- 13. A hybrid cloud uses elements from both the public cloud and private cloud and combines them, binding them with technology that permits their data and applications to be shared. By consenting data and applications to travel between public and private clouds, a hybrid cloud provides more flexibility,in turn helping in optimizing the existing infrastructure.
- 15. Mainly, cloud computing services can be infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS).
- 16. Infrastructure as a service (IaaS) falls under the simplest kind of cloud computing service. In IaaS, we rent the IT infrastructure that we need, like servers, databases, storage, etc., from the cloud provider. A few examples of IaaS comprise of Microsoft Azure and IBM Cloud.
- 17. Platform as a service (PaaS) is a type of cloud computing service that delivers a platform or an environment on a demand basis to develop, test and manage software applications. It is one of the most complex cloud services. A few examples of PaaS are Heroku and Force.com.
- 18. Software as a service (SaaS) is a cloud computing service where we deliver software applications to users over the Internet on a subscription and demand basis. With the aid of a web browser, users can easily connect to the application over the Internet.
