Cards in this deck (20)
- 1High availabilityVMs can spin up fast to help process requests
- 2Disaster recoveryBy taking advantage of cloud-based backup services, data replication, and geo-distribution, you can deploy your apps with the confidence that comes from knowing that your data is safe in the event of disaster.
- 3Fault toleranceThe ability for a Azure to respond to unexpected failures or system crashes as the backup system immediately and automatically takes over with zero downtime
- 4ElasticityAbility to quickly expand or decrease computing resources
- 5ScalabilityScaling vertically or scaling horizontally (able to add/detract instances of resources or to use add RAM/CPUs to VM)
- 6AgilityAbility to rapidly develop, test and launch software applications
- 7Capital Expenditure (CapEx)Money spent by a business or organization on acquiring or maintaining fixed assets, such as land, buildings, and equipment. (Large upfront investments)
- 8Operational Expenditure (OpEx)Ongoing cost for running a product, business, or system on a day-to-day basis, including annual costs (Pay as you go)
- 9Infrastructure as a Service (IaaS)The cloud hosting of a bare server computer, data storage or networking as a service
- 10Platform as a Service (PaaS)Provides cloud customers with an easy-to-configure operating system and on-demand computing capabilities.
- 11Software as a Service (SaaS)A form of cloud computing where a firm subscribes to a third-party software and receives a service that is delivered online.
- 12ServerlessThe cloud service provider automatically provisions, scales, and manages the infrastructure required to run the code (App creator does not need to manage the server)
- 13Private CloudA private cloud consists of computing resources used exclusively by users from one business or organization. A private cloud can be physically located at your organization's on-site (on-premises) datacenter, or it can be hosted by a third-party service provider.
- 14Public CloudServices are offered over the public internet and available to anyone who wants to purchase them. Cloud resources, such as servers and storage, are owned and operated by a third-party cloud service provider, and delivered over the internet.
- 15Hybrid CloudA hybrid cloud is a computing environment that combines a public cloud and a private cloud by allowing data and applications to be shared between them.
- 16RegionA set of datacentres deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network
- 17Availability ZoneWithin a region and each zone has its own separate power, cooling and networking. Used for protecting data from failures
- 18Azure Resource ManagerDeployment and management service for Azure. It provides a management layer that enables you to create, update, and delete resources in your Azure account. You use management features like access control, locks, and tags to secure and organize your resources after deployment.
- 19Geo-distributionYou can deploy apps and data to regional datacenters around the globe, thereby ensuring that your customers always have the best performance in their region.
- 20What pricing model does cloud computing use?Consumption-based model (end users only pay for the resources that they use)
