Top benefits of cloud computingCloud computing is a big shift from the traditional way businesses think about IT resources. Here are seven common reasons organizations are turning to cloud computing services: Cost
Speed
Global scale
Productivity
Performance
Reliability
Security
Types of cloud computingNot all clouds are the same and not one type of cloud computing is right for everyone. Several different models, types, and services have evolved to help offer the right solution for your needs. First, you need to determine the type of cloud deployment, or cloud computing architecture, that your cloud services will be implemented on. There are three different ways to deploy cloud services: on a public cloud, private cloud, or hybrid cloud. Learn more about public, private, and hybrid clouds. Public cloudPublic clouds are owned and operated by a third-party cloud service providers, which deliver their computing resources, like servers and storage, over the Internet. Microsoft Azure is an example of a public cloud. With a public cloud, all hardware, software, and other supporting infrastructure is owned and managed by the cloud provider. You access these services and manage your account using a web browser. Learn more about the public cloud. Private cloudA private cloud refers to cloud computing resources used exclusively by a single business or organization. A private cloud can be physically located on the company’s on-site datacenter. Some companies also pay third-party service providers to host their private cloud. A private cloud is one in which the services and infrastructure are maintained on a private network. Learn more about the private cloud. Hybrid cloudHybrid clouds combine public and private clouds, bound together by technology that allows data and applications to be shared between them. By allowing data and applications to move between private and public clouds, a hybrid cloud gives your business greater flexibility, more deployment options, and helps optimize your existing infrastructure, security, and compliance. Learn more about the hybrid cloud. Types of cloud services: IaaS, PaaS, serverless, and SaaSMost cloud computing services fall into four broad categories: infrastructure as a service (IaaS), platform as a service (PaaS), serverless, and software as a service (SaaS). These are sometimes called the cloud computing "stack" because they build on top of one another. Knowing what they are and how they’re different makes it easier to accomplish your business goals. Infrastructure as a service (IaaS)The most basic category of cloud computing services. With IaaS, you rent IT infrastructure—servers and virtual machines (VMs), storage, networks, operating systems—from a cloud provider on a pay-as-you-go basis. Platform as a service (PaaS)Platform as a service refers to cloud computing services that supply an on-demand environment for developing, testing, delivering, and managing software applications. PaaS is designed to make it easier for developers to quickly create web or mobile apps, without worrying about setting up or managing the underlying infrastructure of servers, storage, network, and databases needed for development. Serverless computingOverlapping with PaaS, serverless computing focuses on building app functionality without spending time continually managing the servers and infrastructure required to do so. The cloud provider handles the setup, capacity planning, and server management for you. Serverless architectures are highly scalable and event-driven, only using resources when a specific function or trigger occurs. Software as a service (SaaS)Software as a service is a method for delivering software applications over the Internet, on demand and typically on a subscription basis. With SaaS, cloud providers host and manage the software application and underlying infrastructure, and handle any maintenance, like software upgrades and security patching. Users connect to the application over the Internet, usually with a web browser on their phone, tablet, or PC. Uses of cloud computingYou’re probably using cloud computing right now, even if you don’t realize it. If you use an online service to send email, edit documents, watch movies or TV, listen to music, play games, or store pictures and other files, it’s likely that cloud computing is making it all possible behind the scenes. The first cloud computing services are barely a decade old, but already a variety of organizations—from tiny startups to global corporations, government agencies to non-profits—are embracing the technology for all sorts of reasons. Here are a few examples of what’s possible today with cloud services from a cloud provider: Create cloud-native applicationsQuickly build, deploy, and scale applications—web, mobile, and API. Take advantage of cloud-native technologies and approaches, such as containers, Kubernetes, microservices architecture, API-driven communication, and DevOps. Test and build applicationsReduce application development cost and time by using cloud infrastructures that can easily be scaled up or down. Store, back up, and recover dataProtect your data more cost-efficiently—and at massive scale—by transferring your data over the Internet to an offsite cloud storage system that’s accessible from any location and any device. Analyze dataUnify your data across teams, divisions, and locations in the cloud. Then use cloud services, such as machine learning and artificial intelligence, to uncover insights for more informed decisions. Stream audio and videoConnect with your audience anywhere, anytime, on any device with high-definition video and audio with global distribution. Embed intelligenceUse intelligent models to help engage customers and provide valuable insights from the data captured. Deliver software on demandAlso known as software as a service (SaaS), on-demand software lets you offer the latest software versions and updates around to customers—anytime they need, anywhere they are. What delivers applications over the cloud using a payPlatform as a service (PaaS) is a cloud computing model where a third-party provider delivers hardware and software tools to users over the internet. Usually, these tools are needed for application development.
What offers a payPay-per-use.
This pricing tactic is mostly used by different cloud-based products and services that charge you for the computing powers/memory/resources/time used. Examples are Amazon Web Services, and Google Cloud Platform.
What in the cloud means that a single instance of a system serves multiple customers?multi-tenancy. in the cloud means that a single instance of a system serves multiple customers, each customer is called and tenant, and multiple tenants can access the same system. single-tenancy. in which each customer or tenant must purchase and maintain an individual system.
What is the software that makes the benefits of cloud computing possible?*Cloud fabric is the software that makes the benefits of cloud computing possible, such as multi-tenancy. *Grid computing is a collection of computers, often geographically dispersed, that are coordinated to solve a common problem.
