In a private cloud, hardware must be purchased for start up and maintenance. In a private cloud, organizations control resources and security. Quick provisioning is a characteristic of the public cloud deployment model. Paying only for what is used is a characteristic of the public cloud deployment model.

Agility means that you can deploy and configure cloud-based resources quickly as app requirements change. Scalability means that you can add RAM, CPU, or entire virtual machines to a configuration. Elasticity means that you can configure cloud-based apps to take advantage of autoscaling, so apps always have the resources they need. High availability means that cloud-based apps can provide a continuous user experience with no apparent downtime, even when things go wrong.

In PaaS, the cloud provider is responsible for the operating system, physical datacenter, physical hosts, and physical network. In PaaS, the customer is responsible for accounts and identities.

PaaS and IaaS use a consumption-based model, so you only pay for what you use.

SaaS allows you to pay to use an existing application on hardware managed by a third party. You supply data and configure access. Customers are only responsible for storage in a private cloud. Customers are responsible for virtual machines and runtime in IaaS and the private cloud.

A resource-lock prevents resources from being accidentally deleted or changed. Resource-tags offer the custom grouping of resources. Policies enforce different rules across all resource configurations so that the configurations stay compliant with corporate standards. An initiative is a way of grouping related policies together.

Management-groups can be used in environments that have multiple subscriptions to streamline the application of governance conditions.

Resource-groups can be used to organize Azure resources. Administrative units are used to delegate the administration of Microsoft Entra resources, such as users and groups.Accounts are used to provide access to resources.

Virtual Machine Scale Sets are an Azure compute resource that you can use to deploy and manage and scale a set of identical virtual machines.

Service-endpoints are used to expose Azure services to a virtual network, providing communication between the two. ExpressRoute is used to connect an on-premises network to Azure. NSGs allow you to configure inbound and outbound rules for virtual networks and virtual machines. Peering allows you to connect virtual networks together.

The Archive storage tier stores data offline and offers the lowest storage costs, but also the highest costs to rehydrate and access data. The Hot storage tier is optimized for storing data that is accessed frequently. Data in the Cool access tier can tolerate slightly lower availability, but still requires high durability, retrieval latency, and throughput characteristics similar to hot data.

Low storage costs and unlimited file formats make blob-storage a good location to store backups and archives. Blob storage can be reached from anywhere by using an internet connection. Azure-Disk-Storage provides disks for Azure virtual machines. Azure-Files supports mounting file storage shares.

Azure Files offers fully managed file shares in the cloud that are accessible via industry-standard SMB and NFS protocols.

Azure-Reservations offers discounted prices on certain Azure services. Azure Reservations can save you up to 72 percent compared to pay-as-you-go prices. To receive a discount, you can reserve services and resources by paying in advance.Spending limits can suspend a subscription when the spend limit is reached.

Azure-Monitor is a platform that collects metric and logging data, such as CPU percentages. The data can be used to trigger autoscaling.

Application-Insights is a feature of Azure Monitor that allows you to monitor running applications, automatically detect performance anomalies, and use built-in analytics tools to see what users do on an app.

Availability-zones are primarily for virtual machines, managed disks, load balancers, and SQL databases.
