Amazon’s AWS and Microsoft’s Azure are the big boys of the cloud computing world, even though AWS is much bigger than Azure.
Revenue from Microsoft Azure grew 72% from 2018 from $7.56 billion to $13 billion. Azure contributed to almost 10.5% of Microsoft’s total revenue in 2019. It has also been noted that the US defense chose Azure in its tactical operations. The last quarter earnings of 2019 grew by 64%.
The exam is intended for candidates who are just beginning to work with cloud-based solutions and services or are new to Azure. Candidates should be familiar with the general technology concepts, including concepts of networking, storage, compute, application support, and application development. Azure Fundamentals can be used to prepare for other Azure role-based or specialty certifications, but it is not a prerequisite for any of them.
Below are the top 40 AZ-900 Microsoft Azure fundamentals Certification exam questions and answers dumps.
Question 2:You have an on-premises application that processes incoming Simple Message Submission Service (SMSS) queue messages and records the data to a log file. You migrate this application to an Azure function app. What kind of cloud service would this be considered?
A. Software-as-a-Service (SaaS)
B. Infrastructure-as-a-Service (IaaS)
D. Platform-as-a-Service (PaaS)
Serverless computing is the abstraction of servers, infrastructure, and operating systems. When you build serverless apps, you don’t need to provision and manage any servers, so you don't have to worry about infrastructure. Serverless computing is driven by the reaction to events and triggers happening in near-real time in the cloud.

Question 35: You have an Azure subscription that contains the following unused resources:
Standard, 5 rules configured
Based on this information, which of the following unused resources should you remove to lower cost?
A and C
The pricing for Standard Load Balancer is based on the number of rules configured (load balancer rules and NAT rules) and data processed. However, there is no hourly charge for the Standard Load Balancer itself when no rules are configured. Since this load balancer contains rules, it should be removed to save money.
In ARM deployment model, there is no charge for dynamic public IP addresses when the associated virtual machine is “stopped-deallocated”. However, you’re charged for a static public IP address irrespective of the associated resource (unless it is part of the first five static ones in the region). This resource should be removed.
Users are able to login to the service, log in to the Access Panel, access applications on the Access Panel and reset passwords. IT administrators are able to create, read, write and delete entries in the directory or provision or de-provision users to applications in the directory.
No SLA is provided for the Free tier of Azure Active Directory.

In Azure, every VM – regardless if Linux or Windows – gets a temporary disk assigned automatically. This temporary disk is located on the physical server (the hypervisor) where the Azure VM is hosted and is non-persistent. Disks used by the operating system or additionally added data disks are persistent disks and stored in Azure Storage.
Azure VM’s can be moved from its current host to new host at any time due to maintenance, hardware failures or other reasons. In such an event, the data from the temporary storage will not preserve or moved to the new host. Apart from the hardware failures, there are many other reasons data from the temporary disk will be lost:
Resizing of the VM
Restarting of the VM
Moving from one host to another
Updating/upgrading of host
Really, the temporary disk should never be used for data that has to be persistent. To avoid misconfiguration, the disk also has the drive label “Temporary Storage” and includes a text file “DATALOSS_WARNING_README.txt”. Read more here…
It depends on the virtual machine type we talk about. Some Azure virtual machines include a Windows operating system license in their price (some even include a SQL Server). Some do not, however, there is an “Azure Hybrid Use Benefit” in certain Microsoft licensing programs, where basically the customer can use its previously acquired software licenses on Azure virtual machines (“bring you own license”). Also, there are Azure virtual machines available with different Linux distributions (both commercial and community), Windows Server license is obviously not included in these. Continue reading here
Hello. Yes They charge you for the disk usage too. So its Disk, Network, License (if Windows Server Instance) and Processor/RAM that are taken into consideration
Why don’t I see the N-Series (vga enabled) VMs in my Azure vm sizes list (I have Bizspark subscription)?
It has nothing to do with BizSpark. N series VMs are generally available since 1 December, 2016 (Azure N-Series: General availability on December 1 ), but only in select Azure datacenter regions. Please consult the Azure Products by Region | Microsoft Azure website for regional availability.
What is a data disk in Azure VM?
What are things to look out for when choosing a location for your Microsoft Azure VM?
The argument in placing a cloud vm would be performance. Performance in the cloud world means cost. The better performance you need the more its going to cost you. But the other side of that is the faster you can solve the problem you are trying to solve. The business problem to evaluate in placement of a VM is loosley these two things: Does increasing the performance of the application provide the overall answers required faster? Are there things you can do to your application that will allow it to better take advantage of cloud capabilities…
Please review Azure Monitor, the built-in monitoring service in Azure. Azure Monitor provides metrics and logs for many services in Azure including VMs. A quick overview : Product documentation: Get started with Azure Monitor Note: As of today (Apr ‘17) Cloud Services metrics are served using an older telemetry pipeline but that is the process of being migrated to Azure Monitor pipeline. You will soon be able to consume Cloud Service metrics via Azure Monitor, the same way you can for Azure VMs, Web Apps or Azure SQL DBs.
Azure Backup introduces a reinforcement expansion to the Azure VM specialist that is running on the VM. This expansion backs up the whole VM. You can back up explicit records and organizers on the Azure VM by running the MARS operator.
Make sure you have VMs in Availability set. Before selecting a VM collect below inputs either from Application or from Performance monitoring team 1. Maximum IOPS required. 2. Maximum size of DB in next 2 years at least. Based on these inputs select the VM size and required storage tier – Standard or Premium. For high performance, you can perform disk stripping if you require more than 5000 IOPS. Also you can configure Backup to URL.
Could I connect to a Linux Azure VM using SSH and private IP through Putty?
Absolutely. You can check your VM’s public IP address on the Azure Portal and SSH into it with the SSH client of your choice. A private IP allows Azure VMs to communicate with other resources in a virtual network or an on-premises network through a VPN or ExpressRoute. So you can SSH into an Azure VM using the private IP from the same virtual network or via VPN / ExpressRoute.
Azure portal ( Microsoft Azure ) now has a feature called Cloud Shell. This basically gets you a command line interface, in the browser, where you can make an authenticated access to Azure resources, including your virtual machines. Both Bash and PowerShell are available, and you can also save your frequently used scripts, etc for later re-use. More details here: Azure Cloud Shell – Browser-Based Command Line | Microsoft Azure

The region prices are related to pricing conditions in particular region. In details it is about tenancy of physical area, prices of the hardware from vendors, the cost of man-hours in a particular region for IT specialists and other Azure datacenter workers, and so on. Unfortunately, I can’t find any reference for that information, I’m talking here personally as the person who works with Azure every day and have a contact with Microsoft teams.
Can we spin up a Windows Azure VM programmatically from a php page? We can assume that we have valid Microsoft Credentials.
The REST Management API is the one you want to go for. Authentication is certificate based. You’ll have to upload a management certificate using the Windows Azure portal in able for your PHP application to authenticate. A good starting point on how to use the Windows Azure REST APIs for management can be found here How to use Windows Azure service management APIs (PHP). Like Rahul suggested, once you have that up-and-running use the Operations on Virtual Machines API set to manipulate your Virtual Machine deployments.
How do you reduce the size of my Azure VM disk?
Hi, Below are some points that would be beneficial for you. 1. Pick the best possible disk size. 2. Compress the panel size in the VM. 3. Export the managed disk to a VHD. 4. Compress the exported VHD. 5. Make another new managed disk from the VHD. 6. Make another VM from the new recently created disk. 7. Alternatively, clean up all the old resources. Hope it helps.
“Lift and shift” is a strategy for migrating a workload to the cloud without redesigning the application or making code changes. Also called rehosting. For more information, see Azure migration center.
Cloud optimized is a strategy for migrating to the cloud by refactoring an application to take advantage of cloud-native features and capabilities.
App Service. A managed service for hosting web apps, mobile app back ends, RESTful APIs, or automated business processes.
Infrastructure-as-a-Service (IaaS) lets you provision individual VMs along with the associated networking and storage components. Then you deploy whatever software and applications you want onto those VMs. This model is the closest to a traditional on-premises environment, except that Microsoft manages the infrastructure. You still manage the individual VMs.
Platform-as-a-Service (PaaS) provides a managed hosting environment, where you can deploy your application without needing to manage VMs or networking resources. Azure App Service is a PaaS service.
Functions-as-a-Service (FaaS) goes even further in removing the need to worry about the hosting environment. In a FaaS model, you simply deploy your code and the service automatically runs it. Azure Functions are a FaaS service.
There is a spectrum from IaaS to pure PaaS. For example, Azure VMs can autoscale by using virtual machine scale sets. This automatic scaling capability isn’t strictly PaaS, but it’s the type of management feature found in PaaS services.
Azure Data Store:
Use the following flowchart to select a candidate data store.
What are unique distinctions and similarities between AWS, Azure and Google Cloud services? For each AWS service, what is the equivalent Azure and Google Cloud service? For each Azure service, what is the corresponding Google Service? AWS Services vs Azure vs Google Services? Side by side comparison between AWS, Google Cloud and Azure Service?
Category: Marketplace Easy-to-deploy and automatically configured third-party applications, including single virtual machine or multiple virtual machine solutions. References: [AWS]:AWS Marketplace [Azure]:Azure Marketplace [Google]:Google Cloud Marketplace Tags: #AWSMarketplace, #AzureMarketPlace, #GoogleMarketplace Differences: They are both digital catalog with thousands of software listings from independent software vendors that make it easy to find, test, buy, and deploy software that runs on their respective cloud platform.
Tags: #AmazonLex, #CogintiveServices, #AzureSpeech, #Api.ai, #DialogFlow, #Tensorflow Differences: api.ai provides us with such a platform which is easy to learn and comprehensive to develop conversation actions. It is a good example of the simplistic approach to solving complex man to machine communication problem using natural language processing in proximity to machine learning. Api.ai supports context based conversations now, which reduces the overhead of handling user context in session parameters. On the other hand in Lex this has to be handled in session. Also, api.ai can be used for both voice and text based conversations (assistant actions can be easily created using api.ai).
Category: Serverless Description: Integrate systems and run backend processes in response to events or schedules without provisioning or managing servers. References: [AWS]:AWS Lambda [Azure]:Azure Functions [Google]:Google Cloud Functions Tags:#AWSLAmbda, #AzureFunctions, #GoogleCloudFunctions Differences: Both AWS Lambda and Microsoft Azure Functions and Google Cloud Functions offer dynamic, configurable triggers that you can use to invoke your functions on their platforms. AWS Lambda, Azure and Google Cloud Functions support Node.js, Python, and C#. The beauty of serverless development is that, with minor changes, the code you write for one service should be portable to another with little effort – simply modify some interfaces, handle any input/output transforms, and an AWS Lambda Node.JS function is indistinguishable from a Microsoft Azure Node.js Function. AWS Lambda provides further support for Python and Java, while Azure Functions provides support for F# and PHP. AWS Lambda is built from the AMI, which runs on Linux, while Microsoft Azure Functions run in a Windows environment. AWS Lambda uses the AWS Machine architecture to reduce the scope of containerization, letting you spin up and tear down individual pieces of functionality in your application at will.
Category:Caching Description:An in-memory–based, distributed caching service that provides a high-performance store typically used to offload non transactional work from a database. References: [AWS]:AWS ElastiCache (works as an in-memory data store and cache to support the most demanding applications requiring sub-millisecond response times.) [Azure]:Azure Cache for Redis (based on the popular software Redis. It is typically used as a cache to improve the performance and scalability of systems that rely heavily on backend data-stores.) [Google]:Memcache (In-memory key-value store, originally intended for caching) Tags:#Redis, #Memcached <Differences: They all support horizontal scaling via sharding.They all improve the performance of web applications by allowing you to retrive information from fast, in-memory caches, instead of relying on slower disk-based databases.”, “Differences”: “ElastiCache supports Memcached and Redis. Memcached Cloud provides various data persistence options as well as remote backups for disaster recovery purposes. Redis offers persistence to disk, Memcache does not. This can be very helpful if you cache lots of data, since you remove the slowness around having a fully cold cache. Redis also offers several extra data structures that Memcache doesn’t— Lists, Sets, Sorted Sets, etc. Memcache only has Key/Value pairs. Memcache is multi-threaded. Redis is single-threaded and event driven. Redis is very fast, but it’ll never be multi-threaded. At hight scale, you can squeeze more connections and transactions out of Memcache. Memcache tends to be more memory efficient. This can make a big difference around the magnitude of 10s of millions or 100s of millions of keys. ElastiCache supports Memcached and Redis. Memcached Cloud provides various data persistence options as well as remote backups for disaster recovery purposes. Redis offers persistence to disk, Memcache does not. This can be very helpful if you cache lots of data, since you remove the slowness around having a fully cold cache. Redis also offers several extra data structures that Memcache doesn’t— Lists, Sets, Sorted Sets, etc. Memcache only has Key/Value pairs. Memcache is multi-threaded. Redis is single-threaded and event driven. Redis is very fast, but it’ll never be multi-threaded. At hight scale, you can squeeze more connections and transactions out of Memcache. Memcache tends to be more memory efficient. This can make a big difference around the magnitude of 10s of millions or 100s of millions of keys.

Basically, it all comes down to what your organizational needs are and if there’s a particular area that’s especially important to your business (ex. serverless, or integration with Microsoft applications).
Some of the main things it comes down to is compute options, pricing, and purchasing options.
Here’s a brief comparison of the compute option features across cloud providers:
Here’s an example of a few instances’ costs (all are Linux OS):
Each provider offers a variety of options to lower costs from the listed On-Demand prices. These can fall under reservations, spot and preemptible instances and contracts.
Both AWS and Azure offer a way for customers to purchase compute capacity in advance in exchange for a discount: AWS Reserved Instances and Azure Reserved Virtual Machine Instances. There are a few interesting variations between the instances across the cloud providers which could affect which is more appealing to a business.
Another discounting mechanism is the idea of spot instances in AWS and low-priority VMs in Azure. These options allow users to purchase unused capacity for a steep discount.
With AWS and Azure, enterprise contracts are available. These are typically aimed at enterprise customers, and encourage large companies to commit to specific levels of usage and spend in exchange for an across-the-board discount – for example, AWS EDPs and Azure Enterprise Agreements.
