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• …

infrastructure as codea practice by where traditional infrastructure management techniques are supplemented,

and often replaced, by ways of working inherited from software development

The infrastructure as code workflow

configure version validate integrate deploy

text editor Git/SVNTests & reviews

LibraryAPI-driven

IaaS

software still, software software too,and peer review

anothersoftware software!

Infrastructure management is not software development

100s lines of configurationfor each sub-system

millions of lines of code in operating systems, in applications, in APIs

What is the role of infrastructure managers

in DevOps practice?

Continuous Delivery

Release software every 6 months

Release software and refresh data, often

DevOps

Shared responsibilityCommon incentives and culture

Microservices

Tightly coupled componentsSlow deployment cycles waiting on

integrated tests teams
