GitHub: Why it's right for open source and (probably) wrong for you
For most of the software development projects in the world, GitHub is the wrong choice for their hosting needs. This is because for most of the world is NOT developing open source software and thus the pricing model for GitHub fights against you, as the GitHub pricing model is designed to charge the daylights out of those who do not develop open source software.
To help me explain this – let us look at two examples.
An open source example
We will use Git itself on GitHub, as our example for open source. Here is a project that is open source and makes use of a three public repositories. Looking at git repository there have been 702 contributors to it.
When you look at the GitHub pricing model this could be run on any plan, including the free one since we are only constrained to have no private repositories in GitHub (you can have unlimited public repositories) and unlimited contributors, which makes it perfect for open source.
When you apply the recommendation I mentioned in yesterday’s post about lightweight repositories to this model (with the free unlimited public repositories), it makes even more sense for open source projects.
A corporate example
The other side of the coin, is a company that is doing consulting or maybe in-house development work that needs to be stored somewhere and (for whatever reason), that work cannot be open sourced. Thus you will need private repositories & you will need a lot of them to follow the lightweight repository principals. Even if you do not intend to follow those principals, you may find that splitting up your repository in an organisational way still creates a lot of repositories.
For example: I worked at a small company (< 30 developers) who would deploy and develop on top of Microsoft CRM & SharePoint. There we split things based on customer (so each customer got a repository) and after 3 years we had almost 200 hundred repositories! For them to use GitHub by simply moving over would mean a custom price negotiated with GitHub, as GitHub doesn’t offer standard pricing to that level. If they changed their structure to properly follow the lightweight repository principle they could’ve easily have tripled the repository count!
So if not GitHub, then who?
In a company, you need to view the issue from the other way around – you need loads of repositories. However you also have another difference to open source, you have limits on something that open source cannot and really do not want to have limited: contributors. In a company you really are only going to have staff or people who are working on the project contributing – so limiting the number of people who are involved is useful. It also gives you an easy way to cost the hosting, because it really boils down to per head costing.
So who offers Git hosting, with unlimited private repositories and charges per head? There are two main players in this space and I have used both found both to be great solutions. BTW I also use GitHub & think it is great too – but for more for collaboration in open source.
BitBucket, which started off life as the Mercurial hosting to GitHub’s Git hosting, now days offers Git too. Their model is pretty simple, unlimited private repositories and basically a cost of $1 per user per month. It is that simple.
Who expected Microsoft to understand Git hosting do well?! They have understood it marvellously with their TF-Service offering which offers unlimited private Git repositories. TF-Service is currently free, but it won’t stay that way and my gut says Microsoft can’t compete with BitBuckets $1 per user cost.
The reason it can’t compete with BitBuckets pricing, is that that TF-Service offers more than code hosting. Microsoft offers build servers, work item tracking and more! Plus if you have Visual Studio Premium or Ultimatethen you also have a MSDN subscription, which means you will be covered by your MSDN subscription so it will be free.
This post is not about knocking GitHub – it is an amazing service & has changed the way the world interacts with code for the better. What this is meant to do is show you that even though it is popular, it may not be the best solution for you!
The REAL number one issue to avoid GitHub
While this discussion is about the pricing model (which is often ignored when choosing a platform), I do need to say what the number one blocker for GitHub is. This is also the number one blocker for TF-Service & BitBucket. Simply put it is my customers. Many of my customers will not give permission for me to host outside the company and in a foreign country and thus we need to run our own infrastructure to accommodate those customers.
