Bare metal (x86)
Pros • Familiar • Performance• Data management
Cons • Static hardware• Slow and expensive provisioning• Low utilization per host
@vpetersson
Virtual machine overview
Pros • Flexible server sizes• Higher host utilization• Simple migration path• Scale with demand2
Cons • “Noisy neighbor” issue• Overhead on host1
• Management1
• Data control2

Container overview
Pros • Fast • Portable• Predictable
Cons • Requires VM or PaaS• Short release cycles1

Container technologies
@vpetersson
Container management
“Container Operating Systems” • CoreOS• Ubuntu’s Snappy Core• RedHat’s Project Atomic• RancherOS
@vpetersson
Container management
Orchestration Tools • (Ansible, Chef, Puppet, Salt etc.)• Google's Kubernates• OpenStack• Docker’s Swarm and Compose• Mesosphere’s DCOS• panamax• shipyard• and many more…

PaaS overview
Pros • Easy to use• Turnkey solution• No management
Cons • Lock-in• Expensive (at scale)• Many limitations
