Cloud computing

-Azure Virtual Machines -Azure Container Instances -Azure App Service -Azure Functions (or serverless computing)

Common Azure Compute Services

are often one of the primary reasons why companies move to the Azure platform. Azure provides a range of options for hosting applications and services.

Compute services

Azure compute resources that you can use to deploy and manage containers.

Container Instances and Azure Kubernetes Service

-lightweight, virtualized application environments. -designed to be quickly created, scaled out, and stopped dynamically. -You can run multiple instances of a containerized application on a single host machine.

Containers

Which of the following choices isn't a benefit of using cloud services? A. Scalability B. Disaster recovery C. High availability D. Geographic isolation

D

-Offline data synchronization. -Connectivity to on-premises data. -Broadcasting push notifications. -Autoscaling to match business needs.

Features of Azure Mobile Services

-Provides the most flexibility. -Organizations determine where to run their applications. -Organizations control security, compliance, or legal requirements.

Hybrid cloud

a computing environment that combines a public cloud and a private cloud by allowing data and applications to be shared between them.

Hybrid cloud

-No CapEx: Users have no up-front costs. -Agility: Applications can be made accessible quickly, and deprovisioned whenever needed. -Management: The shared responsibility model applies; the user manages and maintains the services they have provisioned, and the cloud provider manages and maintains the cloud infrastructure. -Consumption-based model: Organizations pay only for what they use and operate under an Operational Expenditure (OpEx) model. -Skills: Organizations can use the skills and expertise of the cloud provider to ensure workloads are secure, safe, and highly available. -Cloud benefits: Organizations can use the skills and expertise of the cloud provider to ensure workloads are made secure and highly available. -Flexibility: IaaS is the most flexible cloud service because you have control to configure and manage the hardware running your application.

IaaS Advantages

-This cloud service model is the closest to managing physical servers; a cloud provider will keep the hardware up-to-date, but operating system maintenance and network configuration is up to you as the cloud tenant. -An advantage of this cloud service model is rapid deployment of new compute devices. Setting up a new virtual machine is considerably faster than procuring, installing, and configuring a physical server.

Infrastructure-as-a-Service (IaaS)

Fully managed global IoT software as a service (SaaS) solution that makes it easy to connect, monitor, and manage IoT assets at scale.

IoT Central

Fully managed service that allows data analysis models to be pushed directly onto IoT devices, which allows them to react quickly to state changes without needing to consult cloud-based AI models.

IoT Edge

Map complex information and data to solve tasks such as intelligent recommendations and semantic search.

Knowledge mapping (Azure AI Cognitive Services)

These groups help you manage access, policy, and compliance for multiple subscriptions. All subscriptions in a management group automatically inherit the conditions applied to the management group. Top Level L4

Management groups

Allow your apps to process natural language with prebuilt scripts, evaluate sentiment, and learn how to recognize what users want

Natural Language processing (Azure AI Cognitive Services)

-No CapEx: Users have no up-front costs. -Agility: PaaS is more agile than IaaS, and users don't need to configure servers for running applications. -Consumption-based model: Users pay only for what they use, and operate under an OpEx model. -Skills: No deep technical skills are required to deploy, use, and gain the benefits of PaaS. -Cloud benefits: Users can take advantage of the skills and expertise of the cloud provider to ensure that their workloads are made secure and highly available. -Productivity: Users can focus on application development only, because the cloud provider handles all platform management.

PaaS Advantages

Platform limitations. There can be some limitations to a cloud platform that might affect how an application runs. When you're evaluating which PaaS platform is best suited for a workload, be sure to consider any limitations in this area.

PaaS Disadvantages

This cloud service model is a managed hosting environment. The cloud provider manages the virtual machines and networking resources, and the cloud tenant deploys their applications into the managed hosting environment.

Platform-as-a-Service (PaaS)

-Hardware must be purchased for start-up and maintenance. -Organizations have complete control over resources and security. -Organizations are responsible for hardware maintenance and updates.

Private cloud

consists of computing resources used exclusively by users from one business or organization. -can be physically located at your organization's on-site (on-premises) datacenter, or it can be hosted by a third-party service provider.

Private cloud

-No capital expenditures to scale up. -Applications can be quickly provisioned and deprovisioned. -Organizations pay only for what they use.

Public cloud

Services 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.

Public cloud

A manageable item that's available through Azure. Virtual machines (VMs), storage accounts, web apps, databases, and virtual networks are examples

Resource

A container that holds related resources for an Azure solution. -includes resources that you want to manage as a group.

Resource group

Resources are combined into resource groups, which act as a logical container into which Azure resources like web apps, databases, and storage accounts are deployed and managed. L2

Resource groups

are instances of services that you create, like virtual machines, storage, or SQL databases. Bottom level L1

Resources

Service that hosts enterprise SQL Server apps in the cloud.

SQL Server on Azure Virtual Machines (Azure Database Services)

-No CapEx: Users have no up-front costs. -Agility: Users can provide staff with access to the latest software quickly and easily. -Pay-as-you-go pricing model: Users pay for the software they use on a subscription model, typically monthly or yearly, regardless of how much they use the software. -Skills: No deep technical skills are required to deploy, use, and gain the benefits of SaaS. -Flexibility: Users can access the same application data from anywhere.

SaaS Advantage

Software limitations. There can be some limitations to a software application that might affect how users work. Because you're using as-is software, you don't have direct control of features. When you're evaluating which SaaS platform is best suited for a workload, be sure to consider any business needs and software limitations.

SaaS Disadvantage

enables developers to build applications faster by eliminating the need for them to manage infrastructure

Serverless computing

In this cloud service model, the cloud provider manages all aspects of the application environment, such as virtual machines, networking resources, data storage, and applications. The cloud tenant only needs to provide their data to the application managed by the cloud provider.

Software-as-a-Service (SaaS)

Convert spoken audio into text, use voice for verification, or add speaker recognition to your app.

Speech (Azure AI Cognitive Services)

groups together user accounts and the resources that have been created by those user accounts. For each, there are limits or quotas on the amount of resources that you can create and use. -Organizations can use them to manage costs and the resources that are created by users, teams, or projects. L3

Subscriptions
