Currently on my mind:

• Continuous deployment
• Micro-service Architecture in AWS / other cloud providers
• Scaling organisations both in terms of technology and people

Top book recommendations:

• Outliers (Malcolm Gladwell)
• Scaling Up (Verne Harnish)
• The Five Dysfunctions of a Team (Patrick Lencioni)
• Lean In (Sheryl Sandberg)**

** This should be mandatory reading in our industry.
