AWS, MongoDB, and the Economic Realities of Open Source – Stratechery by Ben Thompson

U.S. music industry sales over time

In 1999, music business income in america peaked at $14.6 billion (all numbers are from the RIAA). It is very important be exact, although, about what was being bought:

  • $12.eight billion was from the sale of CDs
  • $1.1 billion was from the sale of cassettes
  • $378 million was from the sale of music movies on bodily media
  • $222.four million was from the sale of CD singles

Briefly, the music business was primarily promoting plastic discs in jewel instances; the music encoded on these discs was a way of differentiating these items of plastic from different ones, however music itself was not being bought.

This will feels like a silly distinction, nevertheless it explains what occurred after that peak:

Music business income plummeted, even because the distribution and availability of music skyrocketed: the difficulty is that folks have been not shopping for plastic discs, which is what the music business was promoting; they have been merely downloading music immediately.

Promoting Comfort

The issue is that recorded music has all the time been nugatory: as soon as a recording is made, it may be copied endlessly, which suggests the availability is successfully infinite; it follows that to seize worth from a recording is dependent upon the imposition of shortage. That’s precisely what plastic discs have been: a finite provide of a bodily good differentiated by their being probably the most handy strategy to get music. Pirating MP3s from websites like Napster or its descendants, although, was much more handy — and cheaper.

As you’ll be able to see from the chart, the business began to stabilize in 2010, and in 2016 returned to progress; 2018 seems to be to be up round 10% from 2017’s $eight.7 billion quantity, and it appears doubtless the business will cross that 1999 peak within the not-too-distant future.

What occurred is that the music business — prodded largely by Spotify, after which Apple — discovered one thing new to promote. No, they’re nonetheless not promoting music; in truth, they’re beating piracy at its personal recreation: the music business is promoting comfort. Get almost any piece of recorded music ever made, for a mere $10/month.

DocumentDB (with MongoDB compatibility)

Final week, from the AWS weblog:

In the present day we’re launching Amazon DocumentDB (with MongoDB compatibility), a quick, scalable, and extremely obtainable doc database that’s designed to be suitable together with your present MongoDB purposes and instruments. Amazon DocumentDB makes use of a purpose-built SSD-based storage layer, with 6x replication throughout three separate Availability Zones. The storage layer is distributed, fault-tolerant, and self-healing, supplying you with the the efficiency, scalability, and availability wanted to run production-scale MongoDB workloads.

The specifics of MongoDB and now DocumentDB usually are not notably essential to this text; principally, MongoDB created a kind of database that’s extra versatile and higher suited to giant quantities of each structured and unstructured knowledge, making it helpful for giant scale purposes that conventional relational databases have been by no means designed to accommodate.

And now you’ll be able to run it on AWS. Type of.

Open Supply Licensing

Like an growing variety of such tasks, MongoDB is open supply…or it was anyhow. MongoDB Inc., a venture-backed firm that IPO’d in October, 2017, made its core database server product obtainable underneath the GNU Affero Common Public License (AGPL).

AGPL is an in depth relative of the GPL, the copyleft license created by Richard Stallman. “Copyleft” signifies that the license permits for the free distribution, use, and modification of copyrighted materials (on this case software program), with the stipulation that those self same rights prolong to all by-product works; that signifies that any venture constructed utilizing GPL code should itself have a GPL license. That is in distinction to “permissive” open supply licenses that permit others to make use of the copyrighted materials nevertheless they want, with no stipulation that by-product works even be open-sourced. AGPL prolonged the GPL to use to software program accessed over a community; because the software program is just getting used, not copied, the GPL wouldn’t triggered, however the finish result’s much more onerous than the GPL.

Each GPL and particularly AGPL are typically very problematic for corporations: Apple, for instance, doesn’t permit software program licensed with the GPL on the App Retailer, as a result of the App Retailer requires that apps be licensed for a single consumer; apps with permissive licenses are nice — their license could be changed — however the GPL, as soon as utilized, can’t be eliminated. AGPL is worse, as a result of its provisions are triggered by customers merely utilizing the software program; that’s why Google bans its use internally. The corporate notes in its open supply documentation:

The license locations restrictions on software program used over a community that are extraordinarily troublesome for Google to adjust to. Utilizing AGPL software program requires that something it hyperlinks to should even be licensed underneath the AGPL. Even should you assume you aren’t linking to something necessary, it nonetheless presents an enormous danger to Google due to how built-in a lot of our code is. The dangers closely outweigh the advantages.

There’s one addendum to the coverage:

In some instances, we might have various licenses obtainable for AGPL licensed code.

That is MongoDB’s enterprise.

MongoDB’s Enterprise Mannequin

MongoDB defined of their S-1:

We consider we’ve got a extremely differentiated enterprise mannequin that mixes the developer mindshare and adoption advantages of open supply with the financial advantages of a proprietary software program subscription enterprise mannequin. To encourage developer utilization, familiarity and adoption of our platform, we provide Group Server as an open supply providing, analogous to a “freemium” providing. Group Server is a free-to-download model of our database that doesn’t embrace all the options of our business platform. This enables builders to guage our platform in a frictionless method, which we consider has contributed to our platform’s reputation amongst builders and pushed enterprise adoption of our subscription providing…

In contrast to software program corporations constructed round third-party open supply tasks, we personal the mental property of our choices since we’re the creators of the software program, enabling our proprietary software program subscription enterprise mannequin…Our main subscription package deal is MongoDB Enterprise Superior, our complete providing for enterprise clients that may be run within the cloud, on-premise or in a hybrid surroundings. MongoDB Enterprise Superior consists of our proprietary database server, superior safety, enterprise administration capabilities, our graphical consumer interface, analytics integrations, technical help and a business license to our platform. We additionally supply MongoDB Atlas, our cloud hosted database-as-a-service, or DBaaS, providing that features complete infrastructure and administration of our Group Server providing.

Principally, MongoDB sells three issues on prime of its open supply database server:

  • Further instruments for enterprise corporations to implement MongoDB
  • A hosted service for smaller corporations to make use of MongoDB
  • Authorized certainty

The significance of this final one cannot be overstated: MongoDB’s enterprise model and hosted service will not be ruled by the AGPL — or, as of late final yr, a brand new MongoDB-created license referred to as the Server Aspect Public License (SSPL). The SSPL is just like the AGPL on steroids: it compels corporations promoting MongoDB-as-a-service to not solely open-source their modifications, but in addition open-source their whole stack.

What AWS Sells

The most important firm promoting software-as-a-service is, in fact, Amazon. That, although, doesn’t imply that Amazon is promoting “software program.” The truth is that software program is not any totally different than music: it’s infinitely reproducible, and thus, in isolation, value nothing.

As an alternative, the worth of software program is usually realized in 3 ways:

  • First is hardware. Probably the most well-known instance is the iPhone, which is the one approach to get hold of iOS, however there are numerous different examples.
  • Second is licenses. This was Microsoft’s core enterprise for many years: licenses bought to OEMs (for the buyer market) or to corporations instantly (for the enterprise market). Certainly, there’s a little bit of irony in that each Microsoft and open supply, for all their historic opposition to one another, each trusted copyright, robust authorized regimes, and corporations doing the proper factor.
  • Third is software-as-a-service. That is Microsoft’s new mannequin, in addition to Amazon’s, and virtually all new enterprise software program corporations. On this case what’s being bought isn’t the software program per se, however relatively the utility of the software program: the corporate doing the promoting does the whole lot else, together with making the software program obtainable reliably.

With that in thoughts, learn once more what AWS introduced final week:

The storage layer is distributed, fault-tolerant, and self-healing, supplying you with the the efficiency, scalability, and availability wanted to run production-scale MongoDB workloads.

AWS just isn’t promoting MongoDB: what they’re promoting is “efficiency, scalability, and availability.” DocumentDB is only one specific space of many the place these advantages are manifested on AWS.

Make no mistake: these advantages are priceless. There’s a secular shift in enterprise computing shifting to the cloud, not as a result of it’s essentially cheaper (though prices are extra intently aligned to utilization), however as a result of efficiency, scalability, and availability are exhausting issues which have little to do with the core competency and level of differentiation of most corporations.

These are, although, the core competency of AWS, which may deliver unmatched scale to bear on fixing them: by successfully working the servers for tens of millions of consumers Amazon can apply extra assets to all of these points than anybody firm might by itself, in addition to develop its personal buyer structure, from datacenter software program right down to customized chips (and drive a tough discount for hardware from suppliers like Intel).

The result’s that “efficiency, scalability, and availability” is a tremendously engaging enterprise: the extra clients AWS has not solely drive that rather more recurring income, but in addition deepen AWS’ moat by permitting the corporate to convey that many extra assets to bear on ever extra obscure use instances, making AWS that rather more engaging to new clients. Microsoft is competing however is a distant second; Google is even additional behind. In truth, even MongoDB’s managed service runs on the three giants: it merely is unnecessary to go it alone.

The Open Supply Conundrum

Thus we now have arrived at a conundrum for open supply corporations:

  • MongoDB leveraged open supply to realize mindshare.
  • MongoDB Inc. constructed a profitable firm promoting further instruments for enterprises to run MongoDB.
  • Increasingly more enterprises don’t need to run their very own software program: they need to rent AWS (or Microsoft or Google) to run it for them, as a result of they worth efficiency, scalability, and availability.

This leaves MongoDB Inc. not in contrast to the document corporations after the arrival of downloads: what they bought was not software program however moderately the instruments that made that software program usable, however these instruments are more and more out of date as computing strikes to the cloud. And now AWS is promoting what enterprises actually need.

Worse, as a result of AWS doesn’t have entry to MongoDB (it is just matching the API) it solely helps MongoDB three.6; the present model is four.zero.5. It’s attainable that if AWS’ service turns into well-liked MongoDB will successfully stagnate: positive, you will get a greater model from MongoDB Inc., however then it’s a must to handle it your self or go the trouble to tie in all your AWS providers with MongoDB’s providing (then once more, the potential for differentiation could also be MongoDB’s salvation, and an necessary lesson for different corporations).

Not that permissive licensing would essentially assist: Redis Labs presents its Redis database underneath a permissive license; that signifies that AWS’ providing is often up-to-date, which is sweet for Redis improvement, however doesn’t assist Redis Labs make any cash. That compelled Redis Labs to vary the licensing on its add-on modules so as to add the “Commons Clause”; this compels service suppliers to pay for his or her use, successfully making them proprietary software program.

It’s onerous to not be sympathetic to MongoDB Inc. and Redis Labs: each spent some huge cash and energy constructing their merchandise, and now Amazon is creating wealth off of them. However that’s the factor: Amazon isn’t creating wealth by promoting software program, they’re being profitable by offering a service that enterprises worth, and each MongoDB and Redis are widespread largely as a result of they have been open supply to start with.

Financial Realities and the Future

Little of what I wrote is new to people within the open supply group: the talk over the influence of cloud providers on open supply has been a strident one for some time now. I feel, although, that the talk will get sidetracked by (comprehensible) discussions about “equity” and what AWS supposedly owes open supply. Sure, corporations like MongoDB Inc. and Redis Labs labored onerous, and sure, AWS is essentially constructed on open supply, however the world is ruled by financial realities, not subjective judgments of equity.

And that’s the reason I began with music: it wasn’t essentially “truthful” that music business gross sales plummeted, and sure, corporations like Apple with its iPod enterprise made billions off of piracy. The one actuality that mattered, although, was that music itself, because of its infinite reproducibility, was as pure a commodity as there could possibly be.

It’s the identical state of affairs with software program: bits on a disk are basically free — simply ask Richard Stallman. In his seminal essay Why Software program Ought to Be Free Stallman wrote:

A replica of a program has almost zero marginal value (and you may pay this value by doing the work your self), so in a free market, it will have almost zero worth. A license charge is a big disincentive to make use of this system. If a extensively helpful program is proprietary, far fewer individuals will use it.

It’s straightforward to point out that the entire contribution of a program to society is decreased by assigning an proprietor to it. Every potential consumer of this system, confronted with the necessity to pay to make use of it, might select to pay, or might forego use of this system. When a consumer chooses to pay, this can be a zero-sum switch of wealth between two events. However every time somebody chooses to forego use of this system, this harms that individual with out benefiting anybody. The sum of damaging numbers and zeros have to be destructive.

However this doesn’t scale back the quantity of labor it takes to develop this system. Consequently, the effectivity of the entire course of, in delivered consumer satisfaction per hour of labor, is decreased.

This tradeoff is inescapable, and it’s truthful to marvel if the golden age of VC-funded open supply corporations will begin to fade (though not open supply usually). The monetization mannequin will depend on the friction of on-premise software program; as soon as cloud computing is dominant, the financial mannequin is rather more difficult.

That, although, ought to give pause to AWS, Microsoft, and Google. It’s arduous to think about them ever paying for open supply software program, however on the similar time, writing (public-facing) software program isn’t essentially the core competency of their cloud companies. They too have benefited from open-source corporations: they supply the means by which their efficiency, scalability, and availability are realized. Proper now everyone seems to be profitable: merely following financial realities might, in the long term, imply everyone seems to be worse off.
