Tech - Balance is the key

In the world of services, a challenge we will face is the granularity of a service. As a principle, it is recommended that a service should be granular. As more and more services are built, this allows developers to 'compose' or 'combine' the services to achieve a desired feature.
But, this has a potential pitfall. Often, there may be a need to combine the services  in a certain way. The options are either to modify the service or to have another service on that does the ​aggregation. There are pros and cons both ways.
Here is an interesting example from 3Scale - http://3scale.github.io/2013/04/18/accelerate-your-mobile-api-with-nginx-and-lua/.
And, an equally interesting article on being pragmatic vs dogmatic - http://dlo.me/archives/2013/04/16/there-is-no-right-way-to-develop-software/.
If  you are building services/API, there may well be a case for sometimes being pragmatic or dogmatic or both! You may need to evaluate each scenario on a case-by-case basis.
