This document discusses infrastructure management in the digital era and the transition to DevOps practices. It provides the following key points: 1) Infrastructure management is evolving from traditional techniques to new ways of working inspired by software development practices like infrastructure as code. 2) Infrastructure as code uses configuration management tools and version control to define infrastructure in code for provisioning, deployment, and updates. 3) For infrastructure managers to support DevOps, their role is shifting from solely managing infrastructure to providing a digital toolbox and optimized experiences through services like a managed cloud platform.

9. Containers versus virtual machines
Databases services
• SQL clusters (Oracle, MSSQL, Maria DB)
• Cassandra rings / Hadoop clusters
• MongoDB clusters
• Redis / Memcached clusters
Storage intensive services
• Object-based storage
• Splunk / ELK / Syslogs / collectd
Sensitive services
• MQ (MQTT, RabbitMQ, JMS)
• Licence servers (FlexLM, WSUS)
• Load balancers / Proxy servers
• VPN endpoints
Start at developer workstation
• Add Dockerfile to every project
• Docker for Mac
• Docker for Windows
Container surrounds
• Docker Swarm
• Kubernetes
• Rancher
• …
New lightweight runtime
• CoreOS / RancherOS
• vSphere Integrated Containers (VIC)
• Microsoft Server 2016

15. infrastructure as code
a practice by where traditional infrastructure
management techniques are supplemented,
and often replaced, by ways of working
inherited from software development

16. The infrastructure as code workflow

17. Infrastructure management is not software development
