Azure Fundamentals (AZ-900) with 100% correct 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.

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.

Azure DevOps Azure DevOps Services (formerly known as Visual Studio Team Services, or VSTS), provides development collaboration tools including high-performance pipelines, free private Git repositories, configurable Kanban boards, and extensive automated and cloud-based load testing. Azure DevTest Labs Quickly create on-demand Windows and Linux environments you can use to test or demo your applications directly from your deployment pipelines. Serverless Computing A cloud-hosted execution environment that runs your code but completely abstracts the underlying hosting environment. You create an instance of the service, and you add your code; no infrastructure configuration or maintenance is required, or even allowed. Containers A virtualized environment for running applications. Just like virtual machines, they are run on top of a host operating system. But unlike VMs, they won't include an operating system for the apps running inside the container. Instead, they bundle the libraries and components needed to run the application and use the existing host OS to run them. Vertical Scaling Known as "scaling up", is the process of adding resources to increase the power of an existing server. Some examples of vertical scaling are: adding more CPUs, or adding more memory. Horizontal Scaling Known as "scaling out", is the process of adding more servers that function together as one unit. For example, you have more than one server processing incoming requests.

Capital Expenditure The decision to spend money on physical infrastructure up front, and then deducting that expense from your tax bill over time. Operational Expense The decision to spend money on services or products now and being billed for them now. Public Cloud When have no local hardware to manage or keep up-to-date - everything runs on your cloud provider's hardware. In some cases, you can save additional costs by sharing computing resources with other cloud users. Private Cloud A cloud environment in your own datacenter and provide self-service access to compute resources to users in your organization. This offers a simulation of a public cloud to your users, but you remain completely responsible for the purchase and maintenance of the hardware and software services you provide Hybrid Cloud The combination of both public and private clouds, allowing you to run your applications in the most appropriate location. For example, you could host a website in the public cloud and link it to a highly secure database hosted in your private cloud. Availability Zones Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. Azure Policy A service in Azure that is a default-allow-and-explicit-deny system that can be used to create, assign, and manage policies. These policies enforce different rules and effects over your resources, so those resources stay compliant with your corporate standards and service level agreements. Azure Data Lake Analytics An on-demand analytics job service that simplifies big data. Instead of deploying, configuring, and tuning hardware, you write queries to transform your data and extract valuable insights. Azure Event Hubs A big data streaming platform and event ingestion service. It can receive and process millions of events per second. Data sent to an event hub can be transformed and stored by using any real-time analytics provider or batching/storage adapters. Azure Monitor A sophisticated set of tools for collecting and analyzing telemetry that allow you to maximize the performance and availability of your cloud and on-premises resources and applications. RBAC for Azure a system that provides fine-grained access management of Azure resources. Locks You may need to lock a subscription, resource group, or resource to prevent other users in your organization from accidentally deleting or modifying critical resources. You can set your lock level to CanNotDelete or ReadOnly. In the portal, the locks are called Delete and Read-only respectively.
