Introduction to Azure Fundamentals Flashcards
What are the basic services provided by all cloud providers?
Compute power and Storage
What is a Hypervisor?
An abstraction layer which separates the computer’s hardware and operating system in a process called Virtualization. In general you have a server, which has a Hypervisor, which supports multiple virtual machines. These machines can run any OS.
What provides connectivity to servers?
A Network Switch
What is Fabric Controller?
A special piece of software run on one server within a Network Switch connection. The Fabric Controller connects to other Fabric Controllers and forms the Orchestrator
What does the Orchestrator do?
It is responsible for everything that happens in Azure, including responding to user requests, when users use the Orchestrator’s Web API
How can you call the Web API?
With many tools, including the user interface of the Azure Portal
What happens when a user makes a request to create a Virtual Machine?
The Orchestrator packages everything that is needed. It picks the best server rack and sends the package and request to the Fabric Controller. Once the Fabric Controller has created the Virtual Machine, the user can connect to it.
What is the Azure Portal?
The gateway to manage everything in your Azure subscription
What is the Azure Portal an alternative to?
command-line tools
What makes the Azure Portal resilient against datacenter failures?
It maintains it’s presence in every Azure Datacenter.
How often does the Azure Portal Update and how long is the downtime?
It updates continuously and requires no downtime for maintenance activities
What is the purpose of Azure Marketplace?
To connect Azure users with Microsoft partners, independent software vendors, and startups that are offering their solutions and services, which are optimized to run on Azure. All solutions and services offered on the Marketplace are certified to run on Azure
What are the 10 main categories of Azure’s services and features?
- Compute: Scale to use for web and mobile apps and build Virtual Machines
- Networking: Connect Cloud and On-Premise Infrastructure by using features like VPNs and Loadbalancing
- Storage: Disk, File, Blob or Archival Storage
- Mobile: Build cross-platform and native apps for any mobile device
- Databases: Use tools to manage data services like SQL, MySQL and Cosmos DB
- Web: Help you build, manage, deploy and scale web applications. Create web apps, publish APIs to services or use Azure-maps to add geo-spacial context to data
- Internet of Things (IoT): Use features to connect, monitor and manage IoT assets. Analyze data as it arrives from sensors and take meaningful action with it
- Big Data: Run analytics on large volumes of data with open source cluster services
- Artificial Intelligence (AI): Make forecasts and use ML to build, train and deploy models to the cloud
- DevOps: Brings together people, processes and technology by automating software delivery. With Azure DevOps you can create, build and release pipelines that provide continuous integrations, delivery and deployment for applications.
Which 5 characteristics do Storage services share?
Durable and highly available with redundancy and replication.
Secure through automatic encryption and role-based access control. Scalable with virtually unlimited storage. Managed, handling maintenance and any critical problems for you. Accessible from anywhere in the world over HTTP or HTTPS.
Through which chain does your Azure Account connect to the Resources provided by Azure?
Account > Subscriptions > Resource groups > Resources
