A Pragmatic Approach to Rock Your API Strategy

Your APIs are to your business what a panel and controls are to a car. Most people have no clue about how a car works under the hood, but knows that if you push the accelerator, the car goes faster, and if you apply your brakes, the car will eventually stop. Similarly, things like climate control, blind spot detection, and adaptive cruise control provide a safer and more enjoyable driving experience without you having to worry about how those systems do what they do. Well, that is exactly how good APIs should work! This white paper explains why you need to and how you can adopt an effective API strategy. It demonstrates the most pragmatic way to do this with general insights and real experiences from some of our consultants on the field.

Open Source - Why Contribute

White Paper

The Open Source Primer: Part 3 - Why Contribute

10/2016

By Jonathan Marsh
Vice President - Strategy, WSO2

Open source communities grow strong when there are many and diverse participants. For many popular projects, there are a few major contributors – usually the authors of the original code – but a long tail of community members that help keep a project current, relevant, and of the highest quality.

There are many motivations for joining an open source community – a software vendor relying on the project has a clear interest in participating. Individuals may participate for their own enjoyment or to build skills and a reputation that boost their career.

But this essay focuses on participation from users, especially for employees of a user organization who participate as part of their job duties. What could be the benefits for contributing such resources to an open source project, for which there are no direct returns?

Protecting Technology Investment

One of the primary drivers for sponsoring an open source project is to protect your investment in the technology. As a user, you value the longterm benefits of a project that remains stable and reliable while evolving along with the new demands that may be placed upon it. By being an active contributor, your needs are represented directly in the project and help drive its direction in a way that aligns well with your needs.

In addition, participation helps build expertise that may be useful should the vendors you use in conjunction with a project become misaligned. In the worst cases a vendor could go out of business, or be acquired by a company with poor alignment with your vision. In this case, any expertise you have in the project will help maintain, influence, or in worst case fork the project to extricate yourself from the commercial relationship.

One common benefit of contributing is to relieve yourself of the sole responsibility to support extensions or improvements. Code you write and successfully contribute is supported and evolved further by the community and by vendors providing additional services.

If you rely on a project and want it to be supported by a vibrant, diverse community, it behooves you to be an integral part of that community. If not you, who?

Awesome Employees

Open source is very attractive to technical staff. With an open source license it’s extremely amenable to go-getters who proactively build expertise in the product (as a user or as a contributor.) Technical staff views the ability to participate and contribute to an open source project as an employee benefit, that is both enjoyable as well as builds their professional capabilities and stature.

Collaboration with peers around a technology helps bring new insights into your organization, and discover what is working well (or not) within other companies.

Being part of a community can also be a source of job candidates. Nothing like seeing someone in action!

Cause It's The Tight Thing To Do

Open source essentially opens up a technology in a way that gives you many of the rights of ownership – influence on the direction, ability to evolve it, decisions about process. If you are a “part-owner” of a technology, and are deriving benefit from it, it is the right thing to do to support the community in proportion to the value you receive and not just be a freeloader. Sure it's technically possible to mooch off a project and let others put up all the investment while you reap the rewards, but if everyone did that where would we be?

Many Ways to Contribute

Now that you are convinced that some level of support or contribution to an open source community is in both your interest and the interest of the society at large, how do you start and what commitment is required?

There are many levels of commitment, you can choose one today and increase or pull back on your commitment as you need to.

Contribute as a Community Member

There are many ways to contribute that don't take much commitment, or even legal review. You can and should get started with them right away.

Spread the word: one of the simplest but indispensable ways you can contribute to an open source project is simply to promote it. Mention it to your peers. Tweet or blog about it. Share your experiences with it. Attend a community event. This helps attract more community and builds momentum around the project. It's simple and it's free!

File bugs/suggest improvements: if you see something that needs to be improved, please share it! Open source benefits hugely from direct interaction with users, and anything positive or negative that you can share will affect the project quickly.

Help others: building some expertise on the product? Share it with others. There are always questions on user forums like stackoverflow.com that could benefit from your knowledge. And by helping others you are building your own reputation as an expert.

Contribute as a Developer

Open source project typically reserve commit and process voting rights to individuals who have proven their capabilities and commitment to the project. But there are many ways to contribute technically to a project that don’t require elevation to committer status – although these activities are precisely what will earn you that status.

Evaluate source code: Take a look at the source code. Ask questions. Engage in the discussion of new features. Suggest improvements. More eyes makes for better code!

Submit fixes as patches: If you see something that needs fixing, just fix it! Without committer access to the source code you can still submit your fix as a "diff." A committer will evaluate it and if it is good will check it in for you. Note that typically these diffs require you to agree to a "Contribution License Agreement," that basically confirms that you will allow the contribution to be released as open source and you don’t know of any intellectual property that it violates. This is basic housekeeping to ensure the open source project maintains clear provenance.

Test release candidates: Let's face it, you can never test too much! If there is a release candidate, try it in your environment to see if it meets the quality bar.

Improve the documentation: Or the home page. Or create a cool logo. Or develop some good training material. Lots of ways to help a project beyond the source code itself, and there is always a need for these less glamorous of tasks.

Become a Committer

Most projects follow a well-established governance process that supports massively distributed work and decision making by a highly distributed group of individuals. One of the best known, and the one WSO2 uses, is the Apache Way.

The Apache Way reserves “committer” status, rights, and obligations to those who have demonstrated their capability and commitment to the project. These rights include full write access to the source code, the ability to vote (primarily on releases, adding new committers, and new features.)

New committers are voted in by existing committers, based solely on their contributions, without regard to who their employer is. It’s a pure meritocracy.

Contributing to WSO2 Projects

At WSO2, there is no corporate interference in project governance. The existing committers vote in new committers based solely on their history of meaningful contribution. This means committers from outside WSO2 are encouraged to participate and welcomed to earn committer status.

Committer status is given to individuals and transcends the employment relationship. A committer changing jobs but still committed to the project retains their status. Please see the collaboration process from the Apache Way ( http://www.apache.org/foundation/how-it-works.html#management) which WSO2 uses as our governance model for all our projects.

Please also see the Community page for instructions on how to make a contribution.

Open Source - TCO Factors

White Paper

The Open Source Primer: Part 2 - TCO Factors

10/2016

By Jonathan Marsh
Vice President - Strategy, WSO2

Total Cost of Ownership (TCO) figures are often published by vendors but can be hard to relate to your own organization or a specific project. Often they involve an over-idealized model of the business. Small deviations between reality and the TCO model assumptions can easily overwhelm the supposed logic of the calculation. In addition too narrow a focus solely on costs (TCO) versus the subtle factors that affect the Return On Investment (ROI) can obscure the true goal.

For these reasons we’d like to begin our discussion of TCO by presenting some factors inherent to open source software that are hard to quantify in a TCO context but have significant impact on the long term outcome:

1. Unimpeded ability to experiment. With open source licensing, you can begin experimenting immediately – no need to obtain a software license, apply for a key to unlock the software, or wait for business hours somewhere to get permission. You can try – and even fail which is a critical part of any innovative environment – with little consequence in terms of time or money.

2. Flexibility. Open source code puts a significant emphasis on flexibility – a wide community representing many diverse interests and points of view naturally leads to software that is fully instrumented with extension points, caters to a wide variety of use cases, and allows faster iteration to accommodate changing requirements. The cost of a tool inflexible in the face of changing requirements or environments can be very steep – either in diminishing ROI or requiring a costly migration to an alternate solution.

3. Protection against lock-in. Software without an open source license by definition provides – by definition – a monopoly to the software vendor. Sometimes this monopoly position develops into tendencies towards arrogance and laziness, and customers have no choice but to put up with this situation because abandoning a vendor also means abandoning the software. With open source licensing, the vendor and the technology are not legally locked together. If you can find a better vendor to support the technology the open source license ensures that you are free to do so. You can support it yourself if you are willing to invest in developing that capability. Alternative vendors are free to spring up without the permission of the original vendor.

4. Keeping vendors honest. As just discussed, under open source licensing, alternatives will spring up or customers will develop the capability to self-support if the there is good technology but the vendor fails to provide value. Where there is a primary vendor, there is constant pressure to ensure that the services and relationship are so good that there is no need to consider an alternative. Ideally, so good that there is little room in the market for alternatives.

5. Developer satisfaction. Many developers are happier and more productive when using open source technologies. They know they can reuse their skills, build a personal relationship with the community, use the technology for DIY projects at home or for charity. They know they will not hit a stone wall where corporate sluggishness or misaligned interests can halt progress. With open source there are no limits to their ability to learn from, debug, commit fixes, and even develop new features for the code.

Let's look at the more traditional measures of TCO and how open source can contribute to them as well:

1. Acquisition cost. Typical software licensing involves a pre-paid license fee upon commencement of development, followed by annual maintenance and support fees. An open source license forgoes the initial license fee typically in favor of an annual subscription specifically designated for support and maintenance. The subscription cost coincides with successful deployment and doesn’t require a large lump sum.

Subscription fees also can be treated as operational expenses instead of capital expenses, which may have advantages in some organizations.

Open source software plays well with other open source software and ensures that the TCO and ROI of each level of the stack can be evaluated independently. Open source software will typically not have hard dependencies on proprietary operating systems, databases, or other technologies.

2. Operating costs. A key component of cost is maintaining “modern” software – upgrading regularly as improvements are made, obtaining service packs, and availability of patches to fix specific issues. Open source tends to provide a faster cadence of point releases, so any improvement or fix can be taken advantage of quickly. There are typically no charges for upgrading an open source product to a new version.

Comparing the cost of a commercial license to an open source support subscription isn't hard – determine a time frame, and estimate the initial license fees, licenses for major upgrades, and annual maintenance fees and compare them over the same period with an annual open source subscription cost.

3. Personnel costs. Personnel costs are related primarily to software quality and ease of use, not necessarily to the type of license. But open source software typically attracts talent, supports the availability of a wide set of third party services such as development and system integration.

WSO2 TCO Factors

WSO2's business model does not allow us to charge license fees for our products. Instead we provide subscription support services and development assistance. When performing a cost comparison, the following considerations may be helpful:

Factor Proprietary license Factor
License fees for production use Requires one-time fees based on CPUs or PVU No fees
License fees for upgrades Major upgrades usually require new license fees No fees
Annual support/ maintenance Annual fee, typically a 15-25% of initial license fees Annual per-JVM subscription fee.
License fees for passive standby use Generally requires fees Supported with no additional fees
License fees for development use Generally requires fees, check the license to see what the non-production permitted uses of each license are No fees Development Support available in hourly bundles
License fees for testing Generally requires fees No fees required – subscription only if SLA support is desired
License fees for staging Generally requires fees No fees required – subscription only if SLA support is desired
License fees for passive standby use May require fees No fees

Open Source Primer

White Paper

The Open Source Primer: Part 1

10/2016

By Jonathan Marsh
Vice President - Strategy, WSO2

Software Licensing 101

Software is a strange product. It exists entirely in the information space, so the marginal cost of a copy is near zero. As DVD distribution has given way to Internet downloads software has even escaped the bonds of corporeal formats - like an advanced intelligence from Star Trek evolving into pure energy - and can be delivered anywhere virtually instantly, at virtually no cost.

The impalpable form of software posed challenges to the early creators of software who wanted to sell it as a valuable new type of product. If you sell a copy that can be copied and distributed at no cost how can you spread the cost of creation across a large set of paying users?

Software licenses were the answer. By not “selling” the software outright creators retain full ownership and use copyright law to limit anyone else from making copies. Then, usually in exchange for a fee, the creator loosens up just enough of the restrictions to attract users to the software. The restrictions usually include:

  • Limiting the use of the software to those paying fees
  • Limiting the installation of the software to a certain set of (physical or virtual) machines
  • Limiting sharing, renting, or reselling of the software
  • Limiting certain uses of the software
  • Limiting examining the source code (traditionally, source code was not licensed and simply kept hidden)
  • Limiting reverse engineering
  • Limiting extending the software or building new software upon it

When you read a software licenses you find it’s mostly about LIMITS.

Limits are reasonable in ensuring that the creator is adequately compensated for their creative investments. But limits on use of the software also translate directly into limits on the business value you can obtain from the software. Some of the unpleasant side effects of these limits on a business include:

  • Dependence on a single vendor. Typically the vendor retains enough rights that you cannot ultimately obtain the software or obtain services from anywhere else. If the interests of the vendor differ from yours, too bad.
  • Lack of control over license fees – the vendor sets them and even after negotiating vigorously the vendor still has final control over the price and any price increases in the future.
  • Misalignment of long term goals. The vendor makes the bulk of their money simply by selling the license – not by ensuring it gets deployed effectively (the problem of shelfware) or by providing the highest quality support. Support is often judged as a cost, instead of a revenue stream tied directly to customer satisfaction. A license sale is not inherently aligned with user value, which is realized by getting the software in production and keeping it going over the long term.
  • Accidental license violations can carry stiff repercussions. For instance, moving from one machine to another is increasingly an automatic process – but does the license allow this? Are additional fees due if for instance the number of cores changes during the move?
  • The customer has limited options for influencing product features and fixes. All they can do is plead with the vendor and hope for the best.
  • The customer has little to no visibility into how the software actually works. This is especially damaging in the security space where more eyes on the source code make for a more secure solution.

And Then Came Open Source

It is no wonder that open source is so attractive – it reverses the premise that software licenses are about limits on the use. It eliminates many of the unpleasant side effects of traditional licensing by promising that the creator will NOT impose such limits.

Open source software is licensed under principles of freedom to use, study, improve, and share the software. The creator of the software, while still owning the intellectual property behind the software, has agreed that others may use the software without the traditional limits of a proprietary license. An open source license has:

  • No fees
  • No limits to installation
  • No limits to sharing, renting, or even reselling
  • No limits to usage
  • No limits to changing, altering, or evolving the software - source code is even provided to encourage this

Many of the negative side effects of commercial licenses are correspondingly reversed:

  • You are NOT dependent on a single vendor. If the vendor isn’t providing value, there is no monopoly over the source code preventing competition. You can switch (or threaten to switch) to another vendor.
  • There are NO license fees on the basic product.
  • The vendor makes money directly proportional to immediate and ongoing value – such as support, documentation, consulting, training, additional warranties, additional features.
  • There is little chance of, and correspondingly less harm from, accidental license violations.
  • The customer has a much greater variety of options for influencing product features and fixes – including sponsoring feature development or contributing features back themselves.
  • The source code is fully available and can be rigorously examined by multiple parties for efficiency, reliability, and security.
  • The source code can be readily archived by anyone – eliminating the complications of code escrow contractual provisions.

Now, it should be clear – while it’s easier to build a quality product using open source collaboration methods, it’s much HARDER to build a viable business creating software if you choose open source licensing. Disarming of the monopoly power of traditional licenses is not for the faint of heart. Many users will use your product for free if they are allowed to do so. You can’t just write great code and wait for the money to flow in, you also have to also invest in value-added services and keep them attractive.

The only thing harder, in the long run, than developing a successful open source business is NOT going open source and trying to compete with vendors who have committed and succeeded at this model.

Open Source Business Models

In fact many, if not most, open source businesses have cheated a little bit on their open source commitment in order to make their businesses grow more reliably. The most common model is an "open core" model, where the core software is available open source, released under a designation such as "community edition." But as soon as enterprise features are needed customers must obtain an "enterprise edition." The enterprise edition typically abandons pure open source licensing and reverts to a traditional license – and the customer therefore loses to a large degree the advantages of open source licensing.

Over time, many customers have found this dual license model disadvantageous. The most demanded new features typically appear in the "enterprise" version rather than in the “community” version – it's a natural move to keep as much monopoly control as possible once you’ve stepped down that path. But at some point the community version really just becomes a teaser, providing a façade of open source, collecting some free improvements contributed by the community, but retaining the majority of the value of those contributions commercially for the vendor.

WSO2 is committed to a 100% Apache-compatible model. There is no community/enterprise version split – every product has all features and is enterprise ready. We provide support services, maintenance, consulting, training, and a variety of other valuable services around the free software, for which we work hard to build a strong value proposition and earn customer loyalty.

Open Source License Types

We would be remiss in omitting a notice that not all open source licenses are created equal. In general there are two families of open source licenses – "permissive" and "copyleft."

Permissive is as it sounds – the user is free to do virtually whatever they like with the software – including creating derivatives and releasing them under a traditional commercial license.

Copyleft licenses require that any derivative works, which might be simple improvements or could be a combination of copyleft code with other pre-existing code, must also be made available under the copyleft license. This requirement scares many in the software industry, as it behooves them to commit upfront to open source license terms in any derivatives, or any other code they have which might be combined with the copyleft software.

This stifles their ability to start coding now and assess the ultimate value of the work, and the appropriate license to apply, later.

In one sense, copyleft protects the authors of the code, from being exploited by others building on and profiting from their work without giving back to the original creators. That is an admirable goal. But it is not one that a lot of businesses are able to commit to in advance. A permissive license allows a business to adopt code, improve it, share it, profit from it, or whatever, without having to make a decision up front about whether to share the derivative back to the community.

WSO2 encourages contributions and derivative works released under an open source license, but does not demand that users pre-agree to return improvements to the community. Especially in the middleware space, it is fairly common that an internal application evolves into a marketable standalone product. It is wise not to constrain future business models. For these reasons WSO2 exclusively provide customers with permissive open source licenses, specifically the most well known, the Apache 2.0 license.

Conclusion

Peter Cochran has said "The world is divided into two kinds of people, those who spend a great deal of time saving money, and those who spend a great deal of money saving time."

WSO2 believes that the combination of free open source software – which can be used and improved by all – together with valuable business services that help customers save time at a reasonable cost – are the ultimate future of the industry. We believe permissive open source licenses provide the greatest alignment between the interests of creators and users of software.

So we encourage you to download and try out our products under the open source "no obligation" license. We encourage you to engage with the WSO2 community – share your experiences, contribute back to the projects, or if you put a value on saving time, explore a commercial relationship with WSO2. We are highly motivated to ensure you are satisfied.
