Azure Fundamentals (AZ-900)questions and answers

Azure Fundamentals (AZ-900)questions and answers Azure Microsoft's cloud computing platform Cloud Computing The delivery of computing services over the Internet using a pay-as-you-go pricing model. Infrastructure as a Service Instead of maintaining CPU's, Memory and Storage in your data center, you rent them for the time that you need them. The cloud provider takes care of maintaining the underlying infrastructure for you. Platform as a Service A complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications. Software as a Service A complete software solution that you purchase on a pay-as-you-go basis from a cloud service provider. You rent the use of an app for your organization, and your users connect to it over the Internet, usually with a web browser. Azure Virtual Machines Windows or Linux virtual machines (VMs) hosted in Azure. Azure Virtual Machine Scale Sets A tool to help you create and manage a group of identical, load balanced VMs. Azure Kubernetes Service A complete orchestration service for containers with distributed architectures with multiple containers. Azure Service Fabric Distributed systems platform. Runs in Azure or on-premises. Azure Batch Managed service for parallel and high-performance computing applications. Azure Container Instances Offers the fastest and simplest way to run a container in Azure. You don't have to manage any virtual machines or configure any additional services. It is a PaaS offering that allows you to upload your containers and execute them directly with automatic elastic scale. Azure Functions An event-driven, serverless compute service for when you're concerned only about the code running your service, and not the underlying platform or infrastructure. They're commonly used when you need to perform work in response to an event, often via a REST request, timer, or message from another Azure service and when that work can be completed quickly, within seconds or less. Azure Virtual Network The fundamental building block for your private network in Azure. It will enable many types of Azure resources, such as Azure Virtual Machines (VM), to securely communicate with each other, the internet, and on-premises networks. While similar to a traditional network that you'd operate in your own data center, it will also bring with it additional benefits of Azure's infrastructure such as scale, availability, and isolation. Azure VPN Gateway A specific type of virtual network gateway that is used to send encrypted traffic between an Azure virtual network and an on-premises location over the public Internet. You can also use a VPN gateway to send encrypted traffic between Azure virtual networks over the Microsoft network. Each virtual network can have only one VPN gateway Azure DNS Provides ultra-fast DNS responses and ultra-high domain availability. Azure Content Delivery Network A distributed network of servers that can efficiently deliver web content to users. It is a way to get content to users in their local region to minimize latency. It can be hosted in Azure or any other location. You can cache content at strategically placed physical nodes across the world and provide better performance to end users. Azure DDoS Protection Protects Azure-hosted applications from distributed denial of service (DDOS) attacks. Azure Traffic Manager A service that uses the DNS server that's closest to the user to direct their client browser to the nearest endpoint, it can also direct a user to the endpoint with the lowest latency. Azure ExpressRoute Connects to Azure over high-bandwidth dedicated secure connections Azure Network Watcher Monitors and diagnoses network issues using scenario-based analysis. Azure Firewall A managed, cloud-based, network security service that protects your Azure Virtual Network resources. It is a fully stateful firewall as a service with built-in high availability and unrestricted cloud scalability. Azure Virtual WAN Creates a unified wide area network (WAN), connecting local and remote sites. Azure Blob storage Storage service for very large objects, such as video files or bitmaps. Azure File storage File shares that you can access and manage like a file server Azure Queue storage A data store for queuing and reliably delivering messages between applications. Azure Table storage A NoSQL store that hosts unstructured data independent of any schema. Azure Cosmos DB globally distributed database service. It supports schema-less data that lets you build highly responsive and always on applications to support the constantly changing data held in NoSQL type databases. Azure Database for MySQL Fully managed and scalable MySQL relational database with high availability and security. Azure Database for PostgreSQL Fully managed and scalable PostgreSQL relational database with high availability and security. SQL Server on VM's Host enterprise SQL Server apps in the cloud. Azure Database Migration Service Migrates your databases to the cloud with no application code changes. Azure Cache for Redis Caches frequently used and static data to reduce data and application latency Azure Database for MariaDB Fully managed and scalable MariaDB relational database with high availability and security. Azure App Service An HTTP-based platform-as-a-service (PaaS) offering in Azure that is designed to host enterprise-grade web-oriented applications. You can meet rigorous performance, scalability, security, and compliance requirements while using a fully managed platform to perform infrastructure maintenance. Microsoft Azure Marketplace An online store that hosts applications that are certified and optimized to run in Azure. Many types of applications are available, ranging from AI + Machine Learning to Web applications. As you'll see in a couple of minutes, deployments from the store are done via the Azure portal using a wizard-style user interface. This user interface makes evaluating different solutions easy. Resource Group A free service used to group together all the services, disks, network interfaces, and other elements that potentially make up our solution as a unit in order to administer them more effectively. Azure Notification Hubs Send push notifications to any platform from any back end. Azure API Management Publish APIs to developers, partners, and employees securely and at scale. Web Apps feature of Azure App Service. Create and deploy mission-critical web apps at scale. Azure SignalR Service Add real-time web functionalities easily. IoT Central Fully-managed global IoT software as a service (SaaS) solution that makes it easy to connect, monitor, and manage your IoT assets at scale. Azure IoT Hub Messaging hub that provides secure communications and monitoring between millions of IoT devices. IoT Edge Push your data analysis models directly onto your IoT devices, allowing them to react quickly to state changes without needing to consult cloud-based AI models.
