The various DevOps pitfalls & How to avoid them
Source:- capgemini.com
DevOps is simple, right? Wrong. The concept of DevOps might be simple, however the implementation is not. The following short blog will try to point out some of the key pitfalls.
There are plenty of DevOps related mistakes an organisations can make. One is to treat DevOps as a solution that can simply be implemented. Another one is to see DevOps as Tools only. Some organisations seem to believe that all that is needed is to move staff from an internal IT / infra focused organisation into Apps driven PODs and “everything” should work.
Many are then surprised and disappointed that instead of faster, better and cheaper its slower, with more outages and spiraling costs. Why? See here my views on the root causes:
Top IT Leadership Mistakes
- Lack of clear vision and communication of the vision
- Assuming DevOps can be bought “in a Box”
- Failing to breakdown the silos…or simply moving them; or worse, creating new ones
- Not providing room for change
- Delegating and failing to engage
- Treating DevOps as an end goal
- Treating DevOps as a simple answer to a simple question
- Starting where there is “less need”
- Trying to move the whole organisation at once
- Failing to “spread the fire” through champions & community
- Not allowing room for new processes & mistakes
Technology
- Not having a DevOps transformation solution
- Not having dynamically provisioned environments. i.e., a cloud
- Ignoring the importance of monitoring & metrics
- Failing to rationalize the toolset
- Not disabling SSH
- Underestimating the importance of versioning
- Codebase not ready for frequent releases
Business

- Not managing agile expectations
- Not giving cross-functional teams a seat at the table

DevOps is not a solution or a simple answer to a complex question and to successfully deploy “DevOps” capabilities an organisation has to address many aspects and avoid numerous pitfalls.
