AZ 900-Module 1 Question and answer with complete solution 2023Cloud Computing the delivery of computing services - including servers, storage, databases, networking, software, analytics, and intelligence over the Internet ("the cloud"). Offers faster innovation, flexible resources, and economies of scale. "Pay-as-you-go" The pricing model used by cloud computing. Typically pay only for cloud services you use, which helps you lower your operating costs, run your infrastructure more efficiently, and scale as your business needs change. Benefits of the Cloud Computing Environment over Physical -High Availability -Scalability (vertically/horizontally) -Elasticity -Agility -Geo-distribution -Disaster recovery High Availability One of the benefits of cloud computing; depending on the service-level agreement (SLA) that you choose, your cloud-based applications can provide a continuous user experience with no apparent downtime even when things go wrong Vertical scalability One of the benefits of cloud computing; computing capacity can be increased by adding additional RAM or CPUs to a virtual machine Horizontal scalability One of the benefits of cloud computing; computing capacity can be increased by adding instances of a resource, such as adding additional virtual machines to your configuration Elasticity One of the benefits of cloud computing; the ability to grow or shrink infrastructure resources dynamically as needed to adapt to workload changes in an autonomic manner, maximizing the use of resources Agility One of the benefits of cloud computing; the ability to react by allocating and deallocating resources quickly; the ability to offer on-demand via self-service where computing resources can be provisioned in minutes. Geo-distribution one of the benefits of cloud computing; applications and data can be deployed to regional datacenters around the globe, thereby ensuring that your customers always have the best performance in their region Disaster recovery one of the benefits of cloud computing; by taking advantage of cloud-based backup services, data replication, and geo-distribution, you can deploy your applications with the confidence that comes from knowing that your data is safe in the event that disaster should occur Cloud service models -Infrastructure-as-a-Service (Iaas) -Platform-as-a-Service (Paas) -Software-as-a-Service (Saas) Infrastructure-as-a-Service (Iaas) one of the cloud service models; considered the most flexible category of cloud services; aims to give you the most control over the provided hardware that runs your application (IT infrastructure servers and virtual machines (VMs), storage, and operating systems). Instead of buying hardware, you rent it; commonly used for migrating workloads, test and dev., & storage/backup/recovery Platform-as-a-Service (Paas) one of the cloud service models; provides an environment for building, testing, and deploying software applications; goal of this service is to help you create an application quickly without managing the underlying infrastructure; commonly used for development framework & analytics or business intelligence
