You can also start to understand the many benefits of Azure cloud computing in Azure and how it can save you a lot of money as well as time.
You should understand Azure Capital expenditure (CapEx) versus operational expenditure (OpEx) and other high level concepts we can go over with you in detail.
In times past, organizations had the need to acquire many physical on-premises environments and bare metal infrastructure in order to get started their business. Significant up-front start up costs of direct investment in actual hardware and the bare metal infrastructure to actually start or expand a business was usually necessary. Azure Microsoft Cloud computing platform indeed provides services to customers without much significant upfront costs or equipment setup time compared to on-premises investments.
There are generally two approaches to investment and they are generally are referred to as follows below.
Capital Expenditure (CapEx): CapEx is usually the spending of certain money on bare metal physical infrastructure up front, and then after that deducting that business expense from your taxes and tax bills over period of time. So CapEx is definitely an up front cost, and this cost usually is considered to have a value that ias going to be reduced as time goes by.
Operational Expenditure (OpEx): OpEx or Operational Expenditure is money that is spent on products or services now and billed also now. The usual custom is to deduct this kind of expense from your financial record tax bills in the same year as the expense had been incurred. In this case there is generally not an upfront cost. You would in this case be paying for a product or service as you use it in actuality.
Capital Expenditure CapEx Azure cloud computing costs
On-premises data centers usually include costs like bare metal server costs.
All hardware components and servers are included. You also incur cost for the Azure solution architect on-premises counterpart that is an infrastructure arhitect that needs to design fault tolerance and proper infrastructure redundancy, this includes but is not limited to bare metal server clustering, as well as proper infrastructure redundancy like the redundant power supplies. You also incur costs for the proper design of the uninterruptible power supplies for reliability. Now suppose a server needs to actually be replaced or a new server must be added to an on-premises datacenter, in this case you need to pay for all the hardware needed like the computer, disks and so on. You need the right RAID settings, redundancy etc. That is a lot of money and all of this can have a big impact on your cash flow in the immediate, because you have to actually pay for the bare metal infrastructrue components right away.
Azure Storage Fundamentals Exam AZ-900 Costs
If you use Azure Storage here are some bare metal prices you don't have to invest in up front. You need all storage hardware components and the cost of supporting these. Depending on the particular Layer 7 and 3 application and of course the level needed of the fault tolerance, you can find out that centralized storage can add up to a lot of money. In the case of larger enterprises and organizations, there can be the creation of multiple tiers of level RAID or similar storage where for instance the more money-demanding fault‐tolerant storage is instead utilized for the purposed of mission-critical applications. In this case the cheaper storage is usually used for what is known as lower priority data for processing.
Azure Virtual Network Fundamentals Exam AZ-900 Costs
Your Azure Virtual Network Fundamentals Exam AZ-900 Costs will be differently structured as opposed to the on premises bare metal costs. Networking at the bare metal level and the price you have to pay for this includes but is not limited to all of your on-premises server hardware components. You need to think of physical routers, switches, hubs, cables, intranet and internet access points, Internet connections in the private like LAN as well as wide area network (WAN) public internet connections and more. There are Files / Storage backup and archive costs and more as well. If you need to copy, or archive, or back up data that also costs money. You can have the backup process set up either to and from the cloud or to and from a private redundant storage array cluster. An upfront cost does exist for the hardware as well as even more additional costs for the purposes of maintenance of the backups as well as storage magnetic tapes for the storage hard drives and so on.
Azure disaster recovery costs versus bare metal disaster recovery costs
You should plan in a bare metal case of yours, about how to recover from a total disaster and continue with the day to day operation of your enterprise. Besides redundancy and server fault tolerance you also need to be creating a data recovery site. You will need things like backup generators. Most things here are considered direct upfront costs, like for building the data recovery site. Please remember that there also tends to be an additional regular ongoing cost for the actual infrastructure itself and the maintenance of this infrastructure.
On-Premises Datacenter infrastructure costs versus Azure Datacenter costs
- on premises energy or electricity
- The actual space needed on the floor so rental or purchase of buildings,
- servers cooling
- building actual maintenance.
- insurance premiums for the building and for the servers in case something happens
Azure Technical personnel
You will need technical experts and probably a full staff of employees to deploy, install, and manage / maintain the bare metal systems in the actual on-premises datacenter and also at the data recovery site as well.
OpEx Azure cloud computing costs
Azure cloud computing means that most of the costs associated with an actual on-premises datacenter are instead shifted to the Microsoft company directly, which is your Azure cloud platform service provider here. You do not need to be even thinking about the underlying physical hardware and bare metal datacenter and all the prices and planning that goes in to it. This is because Microsoft Azure cloud computing actually has a very different kind of pricing that goes into it. For your tax bills and for your purposes of proper financial accounting, all of these costs are generally considered to be operational expenses and OpEx.
Azure Pay As You Go or Azure Reserved VM instance for Azure cloud-based server platforms
If you use a Azure Reserved VM instance or use a Azure Pay As You Go VM instance the cost is usually the philosophy that you pay as you use it.
Pay-per-use models usually require you to be actively managing your Azure subscriptions and knowing the fundamentals to make sure that your actual users are not going to be misusing the Azure services on the modern cloud platform. In this case you can be sure that your provisioned Microsoft Azure accounts are being used in a correct way.
This is because as soon as the Microsoft Azure provider starts to provision the relevant resources, your actual billing starts right then and there. In this case it is therefore your own responsibility to, when needed, actually start deprovisioning the underlying resources from Azure using the Azure Portal or Azure PowerShell when they are not in current use, so as to optimize the costs you are actually incurring on a day to day basis.
Auto-Scaling Azure charges are done automatically on the demanded usage in contrast to the fixed capacity of the underlying hardware or of the virtual hardware.
Azure Cloud computing can bill by number of users (this is called Active Directory in Azure, you should know Azure Active Directory Fundamentals among other things in preparation for Exam AZ-900 and earning the Azure Fundamentals badge). Billing can be CPU usage time, or maybe allocated RAM Random Access Memory components. Billing can be for I/O (Input / Output) operations per second (IOPS) or Input Output Operations per second too. Storage space can also be a billing factor. You should also plan for backup data recovery traffic and backup traffic for the determination of the correct bandwidth needed.
Azure Billing at the user level or organization enterprise levels
Azure subscriptions (also known as a pay-per-use scenario or model) have a tendency to be modern cloud computing billing models that have been designed for both enterprises and the individual users kept in mind. Actually, enterprise organization or individual users tend to be billed for the actual underlying Azure services utilized, and this is done typically on a recurring or regular basis in this case. As an Azure professional you can customize, provision as well as scale the Azure computing resources. This scaling can include the scaling of storage, development platforms, storage containers and more. If you were to be using a dedicated cloud service, you could for example be paying money based on server usage or underlying hardware usage, which is usually abstracted into a virtual container so as for you to never need to worry about bare metal hardware costs with Azure.
Capital Expenditure or CapEx Benefits
When you choose CapEx or Capital Expenditure that means you have been planning your expenses at the very start of a budget period for the project. In this particular case your costs tend to be fixed costs. What fixed costs mean is that you tend to know exactly how much money is actually being spent on the project at the very beginning. This can be very attractive because you may need to be able to make predictions with regards to the actual expenses incurred in advance of a project being started. This can for example be caused by specific budget caveats.
Operational Expenditure or OpEx Benefits
Supply and demand as well as growth factors can be very hard to predict in advance and this can be a huge challenge for the CapEx model described above. The OpEx model favors experimentation at much lower upfront cost, so you can explore right away, sometimes even for free, an Azure service or Azure product such as to understand Azure Service Fabric Fundamentals, as one specific example - or any Azure product you would like to try! Azure does not involve up front large investments in bare metal hardware and networking equipment. In contrast, you would usually pay as little as you need for the actual virtually provisioned infrastructure slice.
OpEx is very attractive when demand highly fluctuates or may not even be known in advance. Azure Cloud services are considered agile. Azure Cloud agility means that you have the power to quickly make changes to an Information Technology (IT) base infrastructure in order to make adaptations to various, greatlty evolving organizational or enterprise-level requirements. Here is a specific example- let us suppose your web application or cloud service has been peaking in usage for one specific month. In this case you can actually use Azure Portal or Azure PowerShell to scale it up and go ahead and pay more money for that specific month - Now let us suppose that in the next month the demand or usage of the resource is now much lower - in this case you can actually scale it down and thereby reduce the specific utilized resources and actually be paying much less money in that month. By the way, please remember that there are autoscaling options too that you can tune for Azure with automation options. Azure Cloud Agility empowers your dynamic cost management, which thereby optimizes the spending of your money on a regular basis in direct response to regularly changing requirements in your organization or enterprise.
