The Azure portal, Microsoft 365, and a large number of SaaS applications are examples of external resources.
Internal resources, including any cloud-based applications created by that company, corporate networks and intranet apps, and intranet apps.

The use of Azure AD is designed for:

Azure, Office 365, Microsoft 365, or Dynamics CRM online subscribers IT administrators App developers

4. How does Azure Data Factory work?


A platform and serverless data integration solution called Azure Data Factory is used to build ETL and ELT pipelines. In order to plan and carry out large-scale data moves and data transformations, it aids in the development of data-driven workflows.

5. Describe Azure Databricks.


The data analytics platform Azure Databricks provide two environments for the creation of data-intensive applications:
  • Cloud Databricks The SQL Analytics
  • Workspace for Azure Databricks
Data and AI workloads can be combined thanks to Azure Databricks' interaction with native cloud provider security, compute, analytics, storage, and AI services.

6. What is Azure Data Lake?


With its limitless storage for organised, semi-structured, or unstructured data of any kind and size, Azure Data Lake is a cloud platform that supports Big Data Analytics.

7. What do Azure resources consist of?


An Azure resource is any object that Azure manages. These are some instances of Azure resources: Storage accounts, virtual networks, virtual computers, etc.

8. What are the responsibilities that Windows Azure has implemented?

 
  • Web Role
  • Worker Role
  • Virtual Machine Role

Web Role: It provides a front-end web solution. Similar to an ASP.NET application, this. IIS and other needed services are provided by Azure when it is assisting.

Worker Role: Provides background service solutions. It can carry out lengthy tasks.

Role of a virtual machine: Virtual machines are used to carry out both worker and web roles. The Azure Virtual Machine on which the worker and web roles are running can be changed by the client thanks to the Virtual Machine Roles.

 



9. Which three sections make up the Windows Azure platform?


Compute, Storage, and Fabric comprise the three main components of Windows Azure.

A. Microsoft Azure Compute

Windows Azure provides a code that the hosting environment can control. Through components, it provides the calculating benefit. Three different roles are supported by Windows Azure:

Web roles supported by IIS7 and used for web application programming
Worker roles are used to manage web roles at the foundational level.
Applications running on Windows Server can be easily transferred to Windows Azure using virtual machine (VM) roles.


B. Storage in Windows Azure

It offers four different kinds of storage services:

Queues for communicating between worker roles and web sections
storing structural data in tables
Windows Azure Drives (VHD) can mount a page BLOB. BLOBs (Binary Large Objects) are used to store contents, records, or enormous amounts of information. These can be downloaded and shared using BLOBs.

C. Microsoft Azure AppFabric

Five services are provided by AppFabric:

Service bus
Access
Caching
Integration
Composite

10. Tell us about Windows Azure AppFabric.


You have the ability to collect diagnostic information from an application running in Windows Azure thanks to Windows Azure Diagnostics. Planning and evaluating capacity makes use of diagnostic data.

11. What sets Windows Azure Queues apart from Windows Azure Service Bus Queues?


The messaging between and within the services is reliable and thorough thanks to Azure Queues. Additionally, they emphasise the simplicity of the rest-based get/put/peek interface.

The larger Windows Azure messaging architecture that enables queuing includes Bus Queues.

12. What does Windows Azure's table storage entail?


A tonne of organised information is stored in the Windows Azure Table storage service. Tables in Windows Azure are ideal for storing structured, non-relational data.

Table: A table is a grouping of objects. Because there is no set structure for items in tables, a single table can contain substances with various configurations of attributes. Many tables may be found in a single record.

Entity: Similar to a database entry, an entity is a configuration of properties. An entity can have a maximum size of 1 MB.

Properties: A name-value pair constitutes a property. Each entity may have up to 252 attributes for data storage. The three system properties that determine a segment key, a row key, and a timestamp are also included in every entity.

13. What does Azure's autoscaling mean?


Scaling out is a common term for scaling by adding additional instances. Additionally, Windows Azure offers scaling up by using larger roles as opposed to more role instances.

We may regulate the execution of our Windows Azure application against its running costs by adding and removing role instances while it is active.

The amount of manual work required to scale an application dynamically is decreased by using an autoscaling solution.

14. What characteristics does Windows Azure have?


On Microsoft data centres, Windows Azure runs and saves the information.

These are the key characteristics:
  • Websites give web designers the ability to put together their sites using ASP.NET, PHP, etc. and deliver them using FTP, Git, etc.
  • Microsoft SQL Server is used to create, expand, and scale the application into the cloud using SQL database, formerly known as Azure database.
  • This is Microsoft's Platform as a Service, which facilitates automated deployment and tiered applications.
 


15. What distinguishes a private cloud from a public cloud?


Private clouds are those that are created just for a single company. They allow a business to use cloud apps while addressing issues with data security and control that commonly arise in a public cloud environment.

Private clouds, also known as internal clouds or enterprise clouds, reside on the Intranet of the company or in a hosted data centre where the data is secure.

16. What exactly are IaaS, PaaS, and SaaS?


IaaS: Infrastructure as a Service is referred to as IaaS. It offers a variety of infrastructure-level features, such as OS and network connectivity. It has a pay-per-use system. Applications are hosted on it. Examples of this architecture include Azure Virtual Machines and VNET.

PaaS stands for the platform as a service. It largely consists of underlying infrastructure abstraction, which enables quicker application development without the complexity of hosting administration. PaaS uses include Azure online apps, cloud services, storage services, etc.

SaaS, or software as a service, is an acronym. These applications are provided with the aid of a service delivery model, in which an organisation merely makes use of the apps. SaaS uses subscription-based charges or advertisements. SaaS examples include Gmail, Office 365, SharePoint Online, and others.

17. Does the Azure Internal Load Balancer have a public DNS or IP address?


No, only private IP addresses are supported by the Azure Internal Load Balancer.

18. How do I define Azure Resource Manager?


Azure's Azure Resource Manager enables management and application deployment in Azure. In the Azure subscription account, the management layer supports the creation, modification, and deletion of resources. It is helpful for controlling locks, access restrictions, and resource security.

19. Describe NSG.


ACL rules that allow or restrict network traffic to subnets, network interface cards (NICs) connected to a subnet, or both, are contained in the NSG or Network Security Group. When an NSG is attached to a subnet, all virtual machines in that subnet are subject to the ACL rules. By connecting the NSG directly to a certain NIC, the traffic to that NIC is restricted.

20. How does Azure Redis Cache work?


An in-memory Redis caching system from Azure called Azure Redis Cache aids in web applications' performance optimization. When a request is made for the first time, data is retrieved from the backend database and put in the Redis cache. Data is retrieved from the Redis cache on subsequent requests. Azure Redis cache uses the Azure Cloud to deliver robust and secure caching solutions.

21. Clarify the Azure storage key


Depending on the needs of the project, an Azure storage key is used to authenticate access to data stored by the Azure storage service. For authentication, there are two categories of storage keys:

Key for primary access
secondary access key to preventing application or website outages

22. In Azure, what is CSPack?


The service package file is created by the command-line programme CSPack, which also gets an application ready for deployment in Azure or Compute Emulator. The cloud service configuration file, or.cscfg file, created using CSPack is included in every project of the cloud service type. It keeps:
  • The number of role instances deployed for each role
  • Thumbprints on the certificate
  • Individual configurations
 


23. The need for Azure Diagnostics API


The Azure Diagnostics API makes it easier to collect diagnostic information from applications running on Azure, such as system event logs and performance monitoring. The cloud service responsibilities need Azure Diagnostics enabled. Using the gathered data, visual chart representations can be made in the future to improve monitoring and generate performance metric warnings.

24. What alternatives do Azure's deployment environments offer?


There are two environments for deployment:

Staging environment: This is where modifications to an application are tested before going live.
Applications are launched in the production environment, where target consumers can access them using DNS-friendly URLs.

25. The definition of Azure Blob Storage


The object storage option for the cloud is called Azure Blob (binary huge object) storage. It is appropriate for immediately supplying documents, media, or text to the browser and is capable of storing vast amounts of unstructured data in text or binary format. Anywhere in the world can access the data.

The containers that the blobs are organised into are connected to user accounts. Three parts make up this service:

Storage account: This can be a generic storage account or a blob storage account that is linked to a Microsoft Azure account.
Containers are used to aggregate blobs together. Blobs can be stored indefinitely in each container. The name of the container needs to be lowercase.
A blob is any form of file or document, regardless of size. Azure supports the following three types of blobs:
Blobby blocks: Up to 195GB of text and binary data, in 50,000 blocks no larger than 4 MB each
Add operations, such as logging data in log files, to blobs.
Page blobs: When reading or writing frequently

26. What do Azure role instances consist of?


Running role settings are used to execute application code on a role instance, which is a virtual machine. According to the description in cloud service configuration files, multiple instances of a role are also permitted.

27. Describe Windows Azure Portal.


Designers access the Windows Azure Portal via their web programme and a Windows Live ID to launch applications. The user then has the option of creating a hosting account for running applications, a storage account for storing data, or both.

Once the designer has a hosting account, he or she can submit applications to Windows Azure using a Windows Azure Portal.

28. Why Azure Fabric?


The main idea at the core is Azure Fabric. It offers an Azure Fabric Controller service. Due to the fact that it manages or oversees:
  • Each and every processing role and resource
  • Activating and sending services
  • keeping track of each service's condition
  • Resource allocation and release
  • establishing a VM, ending it, etc.
  • The most automatic method for updating patches for the installed OS on a virtual machine
 


29. What are your understandings of hybrid clouds?


A hybrid cloud is made up of both internal and external cloud resources, combining private and public cloud resources. When you need to store sensitive information close at hand (private cloud) while using different services from a public cloud, this type of cloud is ideal.

30. A storage key: what is it?


When logging into the storage services account to govern data based on our requirements, storage keys or access keys are used as a validation mode. Although it is an option in Windows Azure to provide a primary access key and a secondary access key, we will only use a single access key to authenticate our application to the storage. To keep the programme from going offline, it is important to share the secondary access key.

31. What does SQL Azure federation mean?


Scalability is achieved in SQL Azure by introducing organisation. Managers and developers can scale information with the aid of a federation. It benefits managers by making information repartitioning and redistribution easier. It gives developers the ability to share and route information. It facilitates routing without a pause in the programme.

32. What and how of Windows Azure Traffic Manager?


Users can use it to manage how the deployed Azure cloud services distribute user traffic. Microsoft Azure offers three different load-balancing techniques. The manager who handles traffic applies a routing strategy to DNS queries made for your domain names and associates the DNS paths with the appropriate instances of your applications.

33. What is a database in SQL Azure?


The SQL Azure database is merely a means of connecting to cloud services so that your database can be stored there. The best way to use PaaS where you can have multiple databases on the same account is using Microsoft Azure.

Similar to SQL Server, Microsoft SQL Azure features excellent accessibility, adaptability, and security at its heart.

The Microsoft Azure SQL Database offers a feature that automatically creates backups of all active databases. To support the 1-hour recovery point goal (RPO) for Geo-Restore, a backup is regularly obtained and geo-repeated.

34. What kinds of storage areas are there in Windows Azure?


A component for storing large amounts of content or binary data, such as images, audio files, and visual documents, is provided by BLOBs. They can be acquired by using REST APIs and are scalable up to 200 terabytes.

Table: Tables are locations where information that is stored as cloud characteristics across multiple devices.

Line: Enabling communication between Web and Worker Role instances is the only goal of a queue. They assist in storing messages that customers may access.

35. What does the term "table" mean in Windows Azure?


You can store your data in an Azure Storage type called a table. An entity is placed on a table and BLOBs are placed in a compartment.

The following are some of a table's main ideas:
  • Tables enable the storage of organised data.
  • A storage account can include 0 to n number of tables.
  • Information is kept in tables as an accumulation of components.
  • A key-value pair of characteristics and an important key make up an element.
 


36. How can Azure functions be protected?


The following methods can be used to secure Azure functions:
  • Security Bureau
  • Record and observe
  • Function access keys for HTTPS
  • Authentication/authorization
  • Permissions
  • secret administration
  • Create usage caps
  • Data Confirmation
  • error management
  • Stop using remote debugging
  • Access restricted by CORS
  • Keep the information encrypted.
  • dependable deployment
  • deployment authorizations
  • Turn off FTP
  • SCM endpoint securely
  • ongoing security verification
  • Network protection
 


37. What does Azure's Conditional Access mean?


Azure AD employs Conditional Access as a tool to make judgments, combine information, and enact corporate regulations.

Through Conditional Access rules, one can install the appropriate access controls as needed to maintain the organization's security and avoid getting in the way of users when unnecessary.

38. When in Azure should you use a static IP address?


When the address connected to the device won't change, Azure uses a static IP address.

39. What is the operation of Azure Site Recovery?


On-premises computers are replicated to a backup data centre and on-premises VMs and physical servers are replicated to Azure through the orchestration and automation of Site Recovery.

It helps with business continuity and disaster recovery (BCDR) by allowing access to apps from the backup site in the event of a primary site outage.

40. What are the advantages of a Traffic Manager?


The advantages of Azure Traffic Manager are as follows:
  • Enhanced efficiency
  • There is no downtime while performing updates or maintenance.
  • On the Windows Azure portal, simple to configure
