With the advancement in cloud technologies more and more companies are getting on the Anything-as-a-Service train but over the years the term services became so overloaded that people are having hard time understanding what it means. As any other technology term you hear lately some clarification may be required to understand what the person in front of you meant with "I sell services".
According to Wikipedia's definition of service (as a system architecture component) it is a set of related software functionalities that can be reused for different purposes, together with the policies that should control its usage. In today's cloud environment I would add two more things to the services definition:
- Those functionalities must be exposed either through interoperable APIs or accessible via browser (i.e. must not be bound to a particular implementation platform)
- And they must be accessible over the network (i.e. can be accessed remotely)
- Services are normally exposed to the "external" world. What this means is that you offer the services outside your organization. Whether this is outside your team, your department or your company it is up to you but you should consider services the offering that generates business value for your organization.
- There are also multi-tenant - this means that the services you offer can be consumed by multiple external entities at the same time without any modifications.
- They are always up - third party businesses will depend on your services and you cannot afford to fail them hence avoiding single point of failure is crucial for the success of services
- Last but not least services must be adopted - if you do not drive adoption through evangelizing, partnerships, good documentation, SDKs etc. the services you offer will not add value for your organization
Transitioning from a traditional software product organization to a services organization requires lot of effort and cultural change, and the best way to approach it is to clearly define the basics from the beginning.
