The Hidden Cost of Technology
Jean-Marie Ferdègue, Keep It Running co-founder
New tech is great• New technology is great
• Tools solve new problems; Kafka, Docker
• And change the way we work; continuous deployments, remote working, cross functional teams
• To deliver more value; rapid iteration, global businesses
BUT
MicroServices• Tech Independence…
• Fragmentation of tech. Runtimes are abstracted by containers but middleware such as RabbitMQ, Kafka, Spark are not
• For every new tech that appears, there’s an outdated tech that teams wouldn’t use anymore, but still exist in production
• Polyglot persistence. Postgres, Cassandra, Neo4J.
The search of the Unicorn
Ops
• Polyglot • 24/7 • Happy to maintain &
improve rather than greenfield innovation
• cost effective • stable in his career
Pace of change
• Business expects more from technology than before
• … but has understood the need to invest
• As a consequence technical efforts are growing
• … creating a potential cost on the culture
New roles of technology• CIO is now business leader,
not tech-only
• Responsibilities; drive innovation and keep lights one
• Business prioritises innovation and sees lights-on as a given
• Both objectives compete on the same resources…
• … making the ability to keep the lights on a competitive advantage
Open Source
• Subject to the same feature-first and crowd pleasing biases than other products
• … potentially at the expense of scalability, monitoring, backup
What does the future hold?
• As more companies embrace micro services principles…
• … the way they run their ops will separate them from competitors
• … or maybe not run Ops themselves
The 4 hidden costs of new technology
• People
• Culture
• Innovate AND Keep It Running
• OpenSource support model
