Microsoft Licensing Services is complicated. you're busy. And you would like to induce your head around Microsoft Licensing quickly. Don't despair. we have a tendency to get you covered.

You'll learn the mandatory Microsoft Licensing Services basics, concepts, fundamentals, licensing models, and touch additional from this page. We'll begin from the fundamentals and end with the core licensing principles of the foremost common Microsoft products.

and therefore the best thing? the data here is condensed into bite-sized paragraphs. And if you would like to be told more, be happy to use the useful links wet everywhere in the text.

Please don't hesitate to come back to this page, because it is an associate degree ever-evolving article. once one thing changes or once we keep in mind that we forgot to say something in the 1st place, we'll update this licensing guide. And you don't wish to miss it.

wherever am I able to realize the official Microsoft Licensing Services guide? no matter whether you browse here, hear from a Microsoft representative or a licensing salesperson, invariably verify it. The sheer quantity of utter b-s, myths, and harmful misconceptions in Microsoft Licensing Services is as beautiful as it is dangerous.

invariably make sure everything by trying it up in Microsoft Product Terms. It covers 90% of Microsoft Licensing Services for organizations, additionally referred to as "volume licensing" (don't worry, we'll justify what this name means). If what you detected or browse contradicts Microsoft Product Terms, it's 's most likely not true.

computer code is licensed, not sold-out Any software, not solely Microsoft', is licensed, not sold.

computer code isn't a physical object. after you pay a licensing fee, you purchase rights to use it. With the return obligatory terms and conditions. If you deviate from the usage terms, you become "non-compliant". you'll be referred to as a "pirate" if you are doing it deliberately.

ne'er infer something. If it's not expressly permitted, it is forbidden.

don't assume anything victimization "common sense". sense doesn't exist in licensing.

Even "free of charge" computer code may have restrictive terms. does one use Visual Studio Community? have you ever checked if you're allowed to use it? No? sleep with now. you'll be up for a surprise.

additional on this subject: what's a software license?

What needs a Microsoft license There are 5 primary classes of Microsoft licenses. There are more, however, we have a tendency to such as you to be told the elemental ideas before we get there.

Desktop software package licenses after you purchase a laptop, it'll doubtless associate with Windows. that's a "Desktop OS license". These licenses preponderantly return pre-installed on end-user hardware. In addition, organizations could buy upgrade licenses for extended functionality.

Desktop Application licenses Unless you're a keen admirer of Open Source, you'd probably think about Microsoft's workplace. These days, there are 2 flavors of Office and, consequently, 2 license types:

User Subscription Licenses for Microsoft 365 (Office 365), Project Online, Visio Online;

Desktop Application licenses for non-online editions like workplace skilled and associate degreed workplace Standard.

Server software package licenses If you're employed for an organization, it most likely uses servers to store files, print, run server software, and perform alternative server functions. Servers running Microsoft software preponderantly use Windows Server operative system.

Server licenses it's uncommon to use solely Windows Server. Server applications, or "servers", are employed in almost every contemporary organization. These may embrace:

info - Microsoft SQL Server,

Email - Microsoft Exchange Server,

ERP - Dynamics 365 (on-premises), and more.

As you'll have guessed, server applications need their various licenses.

consumer Access Licenses, or CALs it's the foremost confusing class of Microsoft licenses for a non-licensing person. CALs don't include software. Some licensing specialists formally decide them "softwareless licenses".

All Microsoft servers require consumer Access Licenses unless there's a certain exception. you'll not use – "access" – server computer code if you merely have licenses for your laptops and servers.

There are 2 kinds of CALs:

User CAL is assigned to a user that becomes a "Licensed User" that will access the server software from any device. that's the dominant model as a result of fashionable users typically having over one device.

Device CAL is assigned to a consumer device, and any user may use the "Licensed Device" to access the server software. it's the simplest CAL for shift employees' victimization of one computer.

consumer Access License basics:

A CAL is merely needed once per person or device. If you would like to access 2 or additional servers of constant type, you merely need one CAL.

each server computer code has its CAL: Windows Server CAL, SQL Server CAL, and others.

Some servers could have multiple "levels" of CALs reckoning on the practicality provided to the commissioned User or users of the commissioned Device, for example, Exchange Enterprise and normal CALs.

extra functionality may need additional CALs. For example, Windows Server requires Windows Server CALs, however, if you would like to supply access to the Windows Server graphical desktop, it'll additionally need Remote Desktop Services CALs.

The same computer code could have totally different licensing rules Rules rely upon Versions and Editions Among several alternative factors, terms and conditions for constant software depend on the commissioned version and licensed edition.

Version indicates once the software was free and its generation, for example, 2012, 2016, and XP.

Editions are additionally critical. For example, SQL Server Enterprise provides additional functionality. It also prices four times over SQL Server Standard.

ne'er confuse versions and editions. If you do, you'll accidentally pay or become non-compliant.

Correct: — What info edition did you install? — SQL Server Enterprise.

Incorrect: — what's the SQL edition on this server? — 2012.

Rules rely upon however you bought a license constant computer code may have totally different terms and conditions supported how you nonheritable a license, for example:

Pre-installed on the laptop,

Purchased in a very pc shop,

Via a Microsoft Enterprise Agreement,

Via a CSP,

and more.

invariably listen to however the license was purchased after you try and discern what you'll do with it.

Also, when you switch from one agreement kind to another, raise your reseller if you'll still use the computer code the method you are doing it now. you'll wish to browse a charming story concerning how our consumer set to migrate from Ea to CSP.

Rules are totally different in physical and virtual machines constant computer code affected from a physical to a virtual machine or instrumentation may have radically totally different licensing necessities. it should have an effect on the formula to calculate the number of licenses and introduce alternative requirements like having mandatory computer code Assurance (we'll justify it soon).

Rules are different for remote connections to servers ranging from 2020, several staff can work from home and use their company software via remote access tools like VPN, Citrix, and Remote Desktop Client.

Desktop software like Microsoft workplace put in on a server to be used remotely has totally different licensing necessities than a basic installation on a laptop.

And there are additional dependencies additionally, to any or all the above, you furthermore may establish:

Is it running in your office, a third-party information center, or the cloud?

can you utilize it for everyday business needs ("production") or develop and check applications ("non-production")?

Who will have access, solely your staff and contractors or partners, suppliers and customers ("external users")?

And even this list isn't exhaustive.

Bottom line:

Licensing depends on usage,

after you amendment however you utilize the software, for example, move it from your workplace ("on-premises") to the cloud, licensing rules and necessities change too,

you ought to not assume you mostly have enough licenses in a very ever-changing IT environment.

computer code Assurance is maintenance+ computer code Assurance (SA) may be a maintenance subscription you'll boost your licenses.

you would like it to:

Have access to the foremost current versions of software,

Run server computer code in a very fashionable virtualized information center ("hyper-converged" is that the buzzword),

shield your data in SQL Server databases with High accessibility and Disaster Recovery copies while not additional licenses, though you can not say "at no additional cost" as computer code Assurance isn't freed from charge,

and there' 's additional reckoning on the Microsoft product.

There also are non-licensing perks and benefits, however, we have a tendency to won't go there. this text may be a licensing crash course, not a Microsoft sales pitch.

In some licensing agreements, Sturmarbeiteilung is compulsory, i.e. you cannot avoid paying for it. If you've got a current Microsoft Enterprise Agreement, rest assured that each license you purchased through its computer code Assurance.

once it's on the point of expiration, you need to renew it a consequent day. there are no thanks to reinstating it later, thus keep an eye fixed on it. Otherwise, if you utilize any of the licensing edges of SA, your perpetual licenses could become useless records within the procurance ledger.

Microsoft license period of time Perpetual licenses Perpetual licenses are evergreen. you buy it once, and unless it's expressly terminated otherwise you sell it on the second-hand market – it's legal in Europe – the license stays with you forever.

once computer code reaches "end-of-life", it solely means Microsoft stopped supporting it and cathartic security updates. Your perpetual licenses are still valid. If anyone tells you otherwise, {they may|they'll|they can} be up to something.

Regrettably, fewer and fever strictly perpetual choices are available, and they are restricted in however you'll use them in a very fashionable office.

Perpetual licenses with computer code Assurance If you've got a Microsoft Enterprise Agreement, most of the licenses will be "perpetual with SA".

The perpetual half doesn't expire.

computer code Assurance may be a subscription, thus it'll expire unless you renew it.

Subscription licenses Subscription licenses are yours for as long as you retain paying. they're not totally different in this regard from a Netflix subscription.

Subscription licenses embrace computer code Assurance or SA-equivalent rights that expire with them.

you need to pay money for the consequent subscription amount ("term") or take away the software once a subscription license expires.

Terms, definitions, and principles of Microsoft Licensing The license must be assigned before the computer code is employed this is often the rationale why:

you need to license all authorized users/devices, even though they'll ne'er access or run the software,

you need to license for the worst case.

For example, Microsoft typically insists that you simply must license each host in a very virtualized cluster for the most virtual machines that will run on the host, even if it never happens. Why? as a result if it happens, you must have already got the desired amount of licenses assigned to the host.

could licenses be assigned to virtual machines? Licenses may solely be assigned to virtual machines in multi-tenant Cloud environments with the subsequent caveats:

Product Terms should permit it for a particular variety of licenses,

The license must be eligible, computer code Assurance is also required,

The supplier must be eligible.

samples of such scenarios:

BYOL to a service provider with License quality through computer code Assurance (may presently get replaced with versatile Virtualisation),

Deploying to Azure with Azure Hybrid Benefit.

there's an idea rife among IT professionals and ITAM managers that SQL Server licenses, for example, are also assigned to virtual machines. that's incorrect. Here' is the right explanation:

If you license SQL Server per virtual core, the calculation is finished per the virtual machine's needments.

However, the desired licenses should then be assigned to the virtual machine host, not the virtual machine itself.

If a virtual machine is in a very cluster and must be "mobile", the corresponding licenses require computer code Assurance, which allows them to travel from a number to a host following the virtual machine.

Re-assigning licenses, the rule of ninety days In traditional circumstances, licenses are also reassigned to a special user or device no more typically than once in 90 days. There are exceptions listed in Product Terms as well as permanent hardware failure or a user feat the organization.

The higher than limitation doesn't apply, and therefore the licenses may be reassigned at any moment if each of the subsequent necessities is true:

The license is eligible for License quality in Server Farms,

The license is roofed with active computer code Assurance.

What happens once a license expires?

once computer code Assurance expires, you'll do the subsequent reckoning on the license and therefore the rights granted by computer code Assurance:

Break virtual clusters,

purchase extra licenses for SQL Server,

Disable remote access to workplace applications,

Downgrade Windows Enterprise to Enterprise LTSC,

and more.

Multiplexing and indirect access once product access is indirect, it will not scale back the quantity of needed user or device licenses.

Here is what we regularly hear from sysadmins and IT support:

"Users hook up with an online server, that solely has one association to the database",

"This computer code uses a coincidental connection pool to the server, and therefore the number of connections ne'er exceeds ten".

Unfortunately, pooling connections or victimization multi-tier design doesn't waver the necessity to license all users and devices connecting to the server. In alternative words, a license is required for the end-point, either user or device, in spite of the hardware and computer code layers between the end and therefore the server.
