Basic Level Azure Interview Questions
What is Microsoft Azure?
Azure is a cloud platform developed by Microsoft to allow businesses to fully run in the cloud. It’s a more flexible cloud platform that offers data storage, service management development, & service hosting. For you to use the cloud services, the cloud platform gives you a pas-as-you-go payment approach to pay for cloud services. I.e. if you have a database & you don’t use it, you will not have to pay.
Azure is comprised of more than 200 services. They include SaaS(Software as a Service) services, IaaS (Infrastructure as a Service) services, PaaS(Platform as a Service) services. The services are in various categories, which includes computing, databases, storage, security, blockchain, content delivery, networking, data warehousing, data lakes, integration technologies, analytics, artificial intelligence, machine learning and more others.
What is Cloud Computing?
Cloud computing is Web-based computing that enables businesses & individuals to use computing resources like virtual machines, processing, databases, memory, storage, services, or pay-as-you-go and event number of calls. Moreover, cloud computing is also a culmination of several attempts at large-scale computing, which has seamless access to nearly limitless resources.
What are the advantages of cloud computing?
- Cloud computing offers maintainability & and auto-updates to new software, databases, OS, & third party software. This will decrease the IT labour cost for a business.
- Cloud computing gives a 24/7 uptime (full time). Data centres and cloud servers are taken control of by the cloud-service provider & no employee is needed to manage that.
- Cloud computing is reliable and scalable. There’s no limit to the number of resources or users. Cloud improves processing & resources as required. If you don’t require resources, you will always scale down to cloud service providers.
- The system enables businesses to cut operations & fix their monthly cost of employees, software licenses and hardware.
- Cloud service providers set up data centers in several locations worldwide, making them faster & reliable.
What is the scalability of cloud computing?
There are two kinds of scalability in cloud computing. They include:
Vertical scaling: This is where the structure yields to improve the present capacity of the machine. It’s similar to expanding RAM from maybe 4GB to 32GB.
Horizontal Scaling: This is where the physical aspect is improved, like putting more machines at work instead of changing the existing ones.
Name important applications of Microsoft Azure?
Some of the most significant application of Microsoft Azure includes Infrastructure Services, Web Applications, Mobile Apps, Cloud Services, Media Services, Storage etc.
What are the various models available for cloud deployment?
Three models are accessible for cloud deployment. They include
Private Cloud: Here, cloud infrastructure is possessed exclusively by us or the exclusive service is offered by the cloud provider. The service includes hosting applications on a devoted server offered by a cloud provider or hosting the application on your on-premise servers.
Public Cloud: With this, cloud infrastructure is publicly owned by the cloud provider. There are chances that these server resources can be shared by more applications.
Hybrid Cloud: In this model, it involves a combination of both private cloud & public cloud. This includes the scenario of utilizing on-premise servers for handling sensitive data, confidential, & use of public cloud features to host public-facing applications.
What’s Azure Resource Manager?
It’s a service offered by Azure to offer management & application placement in Azure. The resource manager offers a management layer that assists the developer in creating, deleting or modify the resources in the Azure subscription account. The feature needs skills like managing access controls, ensuring the security of resources post-deployment, locks & organization of resources.
What is Azure Advisor?
Azure Advisor is a service that gives information on your entire Azure landscape. Moreover, it shows a comprehensive summary of what your system requires and highlights money-saving tactics.
What’s guest OS?
It’s an operating system that operates on a virtual machine hosting a request for a role.
Explain traffic manager importance in Azure?
Major benefits provided by traffic managers include distribution of traffic based on more traffic-routing methods & continuous monitoring of automatic failover and endpoint health when endpoints fail.
Moderate Level Azure Interview Questions
What are Azure availability sets?
These are logical groups consisting of more than one Virtual Machine across various fault domains. Additionally, Azure availability sets guarantee that the applications installed on virtual machines on the availability set are accessible during planned and unplanned maintenance.
What are deployment environments provided by Azure?
It offers 2 deployment environments. They include:
It’s used to keep the live application. Moreover, it can be distinguished from a staging environment that has an URL that is DNS friendly (servicename.cloudapp.net).
This offers a platform for validating changes to the application before it’s made life to production environment.
At this stage, application can be recognized using Globally Unique-Identifier (GUID) in the form of a URL which is GUID.cloudapp.net.
What is Azure DevOps?
This SaaS platform offers development services for making work plans, deploying them, developing applications, and operating together on code. This provides an end-to-end DevOps toolchain for the development & deployment of software. Moreover, it’s able to incorporate several known tools in the market & it’s a suitable way for setting up a DevOps toolchain.
What’s Azure SQL Data Warehouse?
Azure Interview Questions: This is the large storage of data that are collected from a variety of sources from a company & it’s used to control management decisions. Furthermore, data warehouse enables collecting information from various databases on distributed systems or located remotely. It’s built by the combination of the data from more sources which is used for decision making, analytical reporting etc.
Moreover, SQL Data-Warehouse is a cloud-based Enterprise app that enables systems to operate under parallel processing. This allows one to fast analyze a complex query from a large volume of information. It’s also a way out for the Big-Data concepts.
How can one create a Virtual Machine in Powershell?
What is Azure Table Storage?
This is a popular service that’s used across several projects, which assists in storing structured NoSQL information in the cloud. This provides a Key/attribute store that has a schemaless architecture design. The major advantage of using Azure table storage is it’s cost-effective and fast for several kinds of applications. The other advantage is with table storage; one can keep flexible datasets similar to user data for a website application. Also, one can store device information or metadata which the service needs.
Moreover, one can also store any kind of number in the table. The storage account can contain every number of tables to the capacity limit.
With Azure Table storage, one can store a large amount of structured data. NoSQL datastore accepts authentic calls from outside and inside the Azure cloud.
How can you retrieve the state of a particular VM?
What are instance types provided by Azure?
Azure Interview Questions: Azure provides a number of various instance kinds depending on what requirement they fulfil. They include:
- General Purpose: The memory to CPU ratio should be balanced. This offers low – medium traffic web servers and small-medium databases. Moreover, it’s also suitable for testing & development.
- Compute Optimized: This features memory to high CPU ratio. It’s best suited for medium traffic web servers, batch processes, application servers & network appliances.
- Memory-Optimized: This involves a CPU to high memory ratio. It’s suitable for a relational database server, medium-large caches and in-memory analytics.
- Storage Optimized: This offers high disk IO & throughput. It’s suitable for Big Data, SQL Databases and NoSQL.
