CLOUD

Q1). What is a cloud environment?

Cloud environment is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and provided with least management effort or provider interaction. This cloud model promotes availability.

Q2). Why we need Cloud?

On-demand – Resources should be always available when you need them, and you have control over turning them on or off to ensure there’s no lack of resource or wastage happen.

Scalable – You ought to be able to scale (increase or decrease the resource) once necessary. The cloud providers should have enough capacity to meet customer’s needs.

Multi-tenant – generally you’ll be sharing a similar resource (e.g.hardware) with another tenant.
But after all, this is often clear to the client. Cloud supplier shall accountable the safety side, guaranteeing that one tenant won’t be able to access other’s knowledge.

Self-service computation and storage resource – connected processes including: asking, resource provisioning, and deployment should be self-service and automated, involving much less manual processing. If a machine wherever our service is hosted fails, the cloud supplier ought to be able to failover our service right away.

Reliability – Cloud supplier ought to be able to give client responsibility service, committing to uptimes of their service.Utility-based subscription – you may pay the cloud supplier as a utility-based subscription, rather like paying your electricity bill – with none direct investment.

Distributed computing is fundamentally an extraordinary dimension of deliberation over the foundation that can assist you with focusing more on your business rationale without agonizing over facilitating or framework needs. This is the general term utilized for conveying the facilitated administrations over the web. In distributed computing the figuring assets are giving “as an administration”. Much the same as Electricity, you pay to power supplier and get the power at your home and for this you don’t have to make any framewor

Q61). Cloud computing benefits?

  • Scalability
  • Agility
  • High Availability
  • Pay as you go
  • Moving from Capex to Opex
  • Fault Tolerance
  • High Response Time
  • HighBandwidth Low
  • Latency

Scalability

It tends to be named as a capacity of the application to deal with developing measure of work without corrupting the execution. Essentially framework can develop unbounded dependent on interest.
Scalability is of 2 types

  1. Vertical or Scale Up – In this kind of scaling design we increment the limit of the current equipment or machine. For instance, on the off chance that you are having a work area of 4GB RAM and tomorrow you increment the RAM of your machine to 16GB then this is nothing but the vertical scaling.
  2. Level or Scale Out – In this sort of scaling setup we increment the tally of machines without expanding the limit. For instance, on the off chance that you have a server of 8GB RAM and tomorrow you put another server of same RAM, etc. When you do even scaling basically you increment the processing power in parallel so you show signs of improvement execution. This is level

Agility

The framework is anything but difficult to develop as business changes. This characterizes a degree to which your application can be advanced/changed/altered relying upon the business or necessity changes.

High Availability

Essentially this characterizes how much your application is accessible for its end clients. Clients or clients will dependably anticipate zero downtime of the application. High availability implies your application can withstand underneath normal types of downtime scenarios –

  • Hardware failures
  • Application updates
  • Configuration changes
  • OS update restarts
  • Heavy load restarPay as you go

This is the most worthwhile advantage of cloud. With cloud you pay just for what you use. In the event that you are not in the need of assets, you can free them/de-designate them and you are not charged for it. The charging is totally “per minute” charging giving you all the more saving money on expense.

Moving from Capex to Opex

This represents moving from “Capital Expenditure to Operational Expenditure”. Organizations today don’t wish to contribute on equipment as equipment is changing at quick pace. Along these lines, rather than contributing on equipment cost which may wind up out of date after certain time length they are progressively intrigued and willing to pay operational expense on month to month, yearly premise. This is only the Capex to Opex. As Microsoft Azure being “Pay as you go” show it turns out to be anything but difficult to move from Capex to Opex.

Fault Tolerance

It is the capacity of the framework to keep working in full limit and completely practical in case of disappointment of a portion of its parts. This just methods, on the off chance that I have a web application and communicating with database, at that point if the database isn’t open/down still my web application will be accessible for clients.
Microsoft Azure applies different replication and redundancy techniques to make azure hosted services and applications as fault tolerant.

Q62). Types of cloud deployment models?

The summary of these terminologies is as follows –

  1. IaaS – Infrastructure as a Service – a lot of infrastructure level capabilities, for example, an operating framework, organize availability, and so on that are conveyed as pay for use services and can be utilized to have

Example, Azure VM, VNET..

  1. PaaS –Platform as a Service – is about abstracting designers from the hidden infrastructure to enable applications to rapidly be made. This is specifically for designers who are eager to Build applications without stressing over management of facilitating condition at al

Ex, Azure Cloud services, Azure Web Apps, Storage, SQL Azure Database etc.

  1. SaaS – Software as a Service – applications that are conveyed utilizing an administration conveyance demonstrate where associations can basically Consume and utilize the application. Regularly, an association would pay for the utilization of the application

Example, Office 365, Gmail, Saleforce.com, SharePoint online, CRM online and so on.

Q63). What is Public, Private and Hybrid cloud execution as for Azure?

Public Cloud example :

You are running a use of Hospital Management framework on Azure Web Apps or Cloud administration web jobs and supporting backend database you are utilizing is SQL Azure Database. In this precedent as all parts of whole framework [web application and database] are running on Azure itself this turn into your open cloud execution.

Private Cloud example :

You are running a use of Hospital Management framework on VM in your server farm inside your association premises and supporting backend database you are utilizing is SQL server introduced on VM in on premises server farm. In this model as all segments of whole framework [web application and database] are running on premises itself this turn into your private cloud execution.

Hybrid Cloud example :

You are running use of the Hospital Management framework on Azure Web Apps or Cloud administration web jobs and supporting the backend database you are utilizing is SQL server introduced on VM present inside an on-premises server farm. In this precedent as a portion of the segments are running on Azure and few are running on-premises this ends up Hybrid cloud usage.

Q64). What is Azure Resource Manager (ARM) and what are the advantages of ARM over Classic services (Cloud Services)?

Azure Resource Manager (ARM) is the arrangement philosophy/system to convey your Azure parts in Azure (IaaS and PaaS segments). It acts like a holder of numerous resources anyway it can length crosswise over locales and administrations. It is format driven, decisive and idempotent in nature

You can send, oversee, and screen the majority of the resources for your answer as a gathering, instead of taking care of these resources independently. You can over and over send your answer all through the improvement lifecycle and have certainty your resources are conveyed in a reliable state. You can utilize decisive layouts to characterize your organization. You can characterize the conditions between resources so they are conveyed in the right request.

You can apply to get to control to all administrations in your resource gather since Role-Based Access Control (RBAC) is locally incorporated into the administration stage. You can apply labels to resources to sensibly sort out the majority of the resources in your membership.

Q65). Explain about the Log Analytics (Operational Management Suite)?

Log Analytics (OMS) (in the past known by “Operational Insights”) in Azure cook all prerequisites in a single administration and deals with Log Analytics, Automation, Availability and Security at one single spot. It gives single dashboard which gives all subtleties of Logs, IIS Logs, Storage and other Infrastructure Log and Capacity arranging subtleties.

Log Analytics likewise stretch out itself to On Premise foundation, Amazon (AWS) remaining task at hand and Open Stack adjacent to conventional Windows and Linux virtual framework in Azure. Log Analytics additionally empowers you to create Power BI information source from which you can manufacture Power BI visuals for your information. Log Analytics influences OMS which additionally gives you Security and Threat Management related information with every vital detail like Login Information, IP Addresses and so on. It is paid administrations and accompanies 3 distinctive valuing level as Free, Standard and Premium.

It causes you to look Logs over your framework from a solitary dashboard and furthermore enables you to send out the outcomes too. Thus this ends up one single point/dashboard for every one of your logs of all your framework independent whether it is Windows or Linux or On reason or Azure facilitated.

Q66). How to accomplish zero downtime in cloud administration arrangements amid upgrades and all hardware failures?

Keep running something like 2 occasions of every job inside a cloud administration. When we have at least 2 occurrences running for a job in cloud administration then naturally the sending gets appropriated crosswise over various blame and redesign spaces and accomplishes nearly or close to zero downtime.

Fault Domain

Fault domain is a physical unit of disappointment. In basic structure when your VM is associated with power supply and in the event that control supply is down, at that point your VM can not be operational. So VM itself associated with power supply is a Fault domain.

Upgrade Domain

It is an intelligent unit of collection the job occasions and it doesn’t exist physically. When we have 2 cases of job running then consequently every one of the sending or occasions are treated as various upgrade domain. So when an upgrade of visitor OS, host OS or application refresh should be performed then just a single upgrade domain based cases is refreshed while upgrade domain 2 based example continue serving the client’s solicitations. When upgrade of first occasion is finished at that point second upgrade domain based occurrence gets refreshed, etc

Q67). What are the various ways by which an on premises VM can be migrated to Azure?

For movement of on premises VM, we have to comprehend what is the virtualization stage utilized for hosting the VM. Different virtualization systems are HyperV, VMWare and so forth. For making VM on Azure requires VHD document just and that can be gotten from HyperV specifically. On the off chance that VM is facilitated on virtualization stage other than HyperV then we have to initially change over the current VM circles into vhd organization and afterward can be transferred to Azure stockpiling. When the circle documents are available on Azure, VM can be provisioned.

The capacity queue does not give ensure about FIFO nature. The request in which messages are added to queue may not get got in a similar request. Then again, Service Bus Queue gives FIFO requesting ensure if “Message Sessions” are utilized. On the off chance that messages are included with SessionID and collector gets the messages with same SessionID then a partiality is made and the request in which messages were included, message will be gotten also.

Q68). An application front end is hosted on Azure however because of security reasons client need database to be hosted on-premises inside his place of business. What are the distinctive approaches to deal with this connectivity situation in Azure?

Taking a gander at the necessity of associating single on-premises DB machine to Azure facilitated application, Azure VNET based “Point to Site” can be considered as right decision in this situation for Azure to on-premises availability. Point to Site is perfect decision for building up VPN network between on-premises assets and Azure assets where number of assets to be associated is constrained

Q69). What are the other VNET options for accomplishing connectivity with on premise and azure resources?

Site to Site and express route are different choices for accomplishing cross premises network. Site to site to explicitly utilize when you have huge number of assets to be associated.
Now and again, Site to Site or Point to Site availability may present system inactivity as VPN made by these highlights take a shot at open foundation (Internet) as it were. To defeat on this circumstance “Express Route” alternative can be taken which offers devoted Leased Line put together offering to defeat with respect to inertness issue.

This is not supported. You cannot use the Azure Resource Manager to deploy a VM into a virtual network that was created using classic deployment.

Q144) What are the various power states of a VM?

Power State
 
Description
Starting Indicates the virtual machine is being started.
 
Running Indicates that the virtual machine is running.
Stopping Indicates that the virtual machine is being stopped.
Stopped Indicates that the virtual machine is topped. Note that virtual machine Stopped state still incurs compute charges.
 
Deallocating Indicates that the virtual machine is being deallocated.
 
Deallocated Indicates that the virtual machine is completely removed from the hypervisor but still available in the control plane. Do no incur compute charges.
 

Azure Availability Services:

Q145) What are virtual machine scale sets in Azure?

Virtual machine scale sets are an Azure compute resource that you can use to deploy and manage a set of identical VMs. With all VMs configured the same scale sets are designed to support true auto scale, and not pre-provisioning of VMs is required. So it’s easier to build large-scale services that target bit computer, big data and containerized workloads.

Q146) What are Fault Domains?

A fault domain is a logical group of underlying hardware that share a common power source and network switch, similar to a rack within an on-premise data-center. As you create VMs within an availability set, the Azure platform automatically distributes your VMs across these fault domains. This approach limits the impact of potential physical hardware failures, network outages, or power interruptions.

Q147) What are Update Domains?

An update domain is a logical group of underlying hardware that can undergo maintenance or can be rebooted at the same time. As you create VMs within an availability set, the Azure platform automatically distributes your VMs across these update domains. This approach ensures that at least one instance of your application always remains running as the Azure platform undergoes periodic maintenance. The order of update domains being rebooted may not proceed sequentially during planned maintenance, but only one update domain is rebooted at a time.

Q148) Are data disks supported within Scale Sets?

Yes. A scale set can define an attached data disks configuration that applies to all VMs in the set

Q148) Do scale sets work with Azure availability sets?

Yes. A scale set is an implicit availability set with 3 fault domains and 5 update domains.

Q149) Is it possible to add an existing VM to an availability set?

No. If you want your VM to be part of an availability set, you need to create the VM within the set. There currently no way to add a VM to an availability set after it has been created.

Identity & Access Management:

Q150) What are the differences between the Subscription Administrator & Directory Administrator?

Service Administrator: By default, one is assigned the Subscription Administrator role when he/she signs up for Azure. A subscription Admin can use either a Microsoft account or a work or school account from the directory that the Azure subscriptions I associated with. This role is authorized to manage services in the Azure portal if others need to sign in and access services by using the same subscription, you can add them as co-admin.

Directory Administrator: Azure AD has a different set of admin roles to manage the directory and identity-related features. These admins will have access to various features in the Azure Portal or the Azure Classic portal. The admin’s role determines what they can do, like create or edit users, assign administrative roles to others, reset user passwords, manage user licenses, or mange domain.

Q151) Why is Azure Active Directory used?

Azure Active Directory is an Identity and Access Management system. It is used to grant access to your employees to specific products and services in your network.

Q152) What happens when you exhaust the maximum failed attempts for authenticating yourself via Azure AD?

We use a more sophisticated strategy to lock accounts. This is based on the IP address of the request and the passwords entered. The duration of the lockout also increases based on the likelihood that it is an attack.

Networking:

Q153) What are Network Security Groups?

A network security group (NSG) contains a list of Access Control List (ACL) rules that allow or deny network traffic to subnets, NICs, or both. NSGs can be associated with either subnets or individual NICs connected to a subnet. When an NSG is associated with a subnet, the ACL rules apply to all the VMs in that subnet. In addition, traffic to an individual NIC can be restricted by associating an NSG directly to a NIC.

Q154) What is a VNet?

VNet is a representation of your own network in the cloud. It logically isolates your instances launched in the cloud, from the rest of your resources.

Q155) How to restrict inbound or outbound traffic flow to VNet-connected resources?

With help of deployment Network Security Groups (NSGs) to individual subnets within a VNet, NICs attached to a VNet, or both.

Q156) Can we deploy a dedicated firewall between VNet-connected resources?

You can deploy a firewall network virtual appliance from several vendors through the Azure Marketplace.

Q157) Can we configure DNS servers for a VNet?

We can specify DNS server IP addresses in the VNet settings. The setting is applied as the default DNS server(s) for all VMs in the VNet.

Q158) Virtual Network Site-to-site – VPN Gateway

A site-to-site VPN allows you to create a secure connection between your on-premises site and your virtual network. We use industry standard IPsec VPN in Azure.

So we are interoperable with most VPN devices. Setting up a virtual network is free of charge. However, we do charge for the VPN gateway that connects to on-premises and other virtual networks in Azure. This charge is based on the amount of time that gateway is provisioned and available.

ExpressRoute
  • An ExpressRoute lets you create private connections between Azure datacenters and infrastructure that’s on your premises or in a co-location environment.
  • ExpressRoute connections do not go over the public Internet, and offer more reliability, faster speeds, lower latencies and higher security than typical connections over the Internet.
VNets Peering

Virtual network peering enables you to seamlessly connect two Azure virtual networks. Once peered, the virtual networks appear as one, for connectivity purposes.

The traffic between virtual machines in the peered virtual networks is routed through the Microsoft backbone infrastructure, much like traffic is routed between virtual machines in the same virtual network, through private IP addresses only. Azure supports:

  • VNet peering – Connecting VNets within the same Azure region
  • Global VNet peering – Connecting VNets across Azure regions

Storage:

Q159) Are there any scale limitations for customers using managed disks?

Managed Disks eliminates the limits associated with storage accounts. However, the number of managed disks per subscription is limited to 2000 by default.

Q160) How much storage can I use with a virtual machine?

  • Each data disk can be up to 1 TB. The number of data disks which you can use depends on the size of the virtual machine.
  • Azure Managed Disks are the new and recommended disk storage offerings for use with Azure Virtual Machines for persistent storage of data.
  • You can use multiple Managed Disks with each Virtual Machine. Managed Disks offer two types of durable storage options: Premium and Standard Managed Disks.
  • Azure storage accounts can also provide storage for the operating system disk and any data disks. Each disk is a .vhd file stored as a page blob.

Azure AD

Q179) Can I create multiple managed domains for a single Azure AD directory?

No. You can only create a single managed domain serviced by Azure AD Domain Services for a single Azure AD directory.

Q180) Can I enable Azure AD Domain Services in a Classic virtual network?

Classic virtual networks aren’t supported for new deployments. Existing managed domains deployed in Classic virtual networks continue to be supported.

Q181) Can I enable Azure AD Domain Services in an Azure Resource Manager virtual network?

Yes. Azure AD Domain Services can be enabled in an Azure Resource Manager virtual network. Classic Azure virtual networks are no longer supported for when you create a new managed domain.

Q182) Can I migrate my existing managed domain from a Classic virtual network to a Resource Manager virtual network?

Yes, this feature is in preview. For more information, see Migrate Azure AD Domain Services from the Classic virtual network model to Resource Manager (preview).

Q183) Can I enable Azure AD Domain Services in an Azure CSP (Cloud Solution Provider) subscription?

Yes. For more information, see how to enable Azure AD Domain Services in Azure CSP subscriptions.

Q184) Can I enable Azure AD Domain Services in a federated Azure AD directory? I do not synchronize password hashes to Azure AD. Can I enable Azure AD Domain Services for this directory?

No. To authenticate users via NTLM or Kerberos, Azure AD Domain Services needs access to the password hashes of user accounts. In a federated directory, password hashes aren’t stored in the Azure AD directory. Therefore, Azure AD Domain Services doesn’t work with such Azure AD directories.

Q185) Can I make Azure AD Domain Services available in multiple virtual networks within my subscription?

The service itself doesn’t directly support this scenario. Your managed domain is available in only one virtual network at a time. However, you can configure connectivity between multiple virtual networks to expose Azure AD Domain Services to other virtual networks. For more information, see how to connect virtual networks in Azure using VPN gateways or virtual network peering.

Q186) Can I enable Azure AD Domain Services using PowerShell?

Yes. For more information, see how to enable Azure AD Domain Services using PowerShell.

Q187) Can I enable Azure AD Domain Services using a Resource Manager Template?

Yes, you can create an Azure AD Domain Services managed domain using a Resource Manager template. A service principal and Azure AD group for administration must be created using the Azure portal or Azure PowerShell before the template is deployed. When you create an Azure AD Domain Services managed domain in the Azure portal, there’s an option to export the template for use with additional deployments. There’s also an example template in the GitHub templates sample repo.

Q188) Can I add domain controllers to an Azure AD Domain Services managed domain?

No. The domain provided by Azure AD Domain Services is a managed domain. You don’t need to provision, configure, or otherwise manage domain controllers for this domain. These management activities are provided as a service by Microsoft. Therefore, you can’t add additional domain controllers (read-write or read-only) for the managed domain.

Q189) Can guest users invited to my directory use Azure AD Domain Services?

No. Guest users invited to your Azure AD directory using the Azure AD B2B invite process are synchronized into your Azure AD Domain Services managed domain. However, passwords for these users aren’t stored in your Azure AD directory. Therefore, Azure AD Domain Services has no way to synchronize NTLM and Kerberos hashes for these users into your managed domain. Such users can’t sign in or join computers to the managed domain.

Q190) Can I move an existing Azure AD Domain Services managed domain to a different subscription, resource group, region, or virtual network?

No. After you create an Azure AD Domain Services managed domain, you can’t then move the instance to a different resource group, virtual network, subscription, etc. Take care to select the most appropriate subscription, resource group, region, and virtual network when you deploy the Azure AD DS instance.
