4. Overview • XaaS overview • Abstraction layers • Technology overview • Orchestration layers @vpetersson
5. PaaS SaaS IaaS Bare metal Abstraction @vpetersson
6. Mainframes Time* Bare metal (x86) Virtual machines Containers IaaS layer PaaS layer ( ) @vpetersson * Not exactly true :)
7. Mainframes Pros • Powerful • Compact • Reliable Cons • Expensive • Custom / not portable • Hard to program/maintain1 @vpetersson 1 Not entirely true anymore
8. Bare metal (x86) Pros • Familiar • Performance • Data management Cons • Static hardware • Slow and expensive provisioning • Low utilization per host @vpetersson
9. 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 1 If self-hosted 2 If cloud based @vpetersson
10. Virtual machine technologies @vpetersson
11. Virtual machine management @vpetersson
12. Container overview Pros • Fast • Portable • Predictable • Easy to audit Cons • Requires VM or PaaS • Short release cycles1 1For new container environments @vpetersson
13. Container technologies @vpetersson
14. Container management “Container Operating Systems” • CoreOS • Ubuntu’s Snappy Core • RedHat’s Project Atomic • RancherOS @vpetersson
15. Container management Orchestration Tools • (Ansible, Chef, Puppet, Salt etc.) • Google's Kubernates • OpenStack • Docker’s Swarm and Compose • Mesosphere’s DCOS/Mesos • panamax • shipyard • and many more… • Including Windows and VMware @vpetersson
16. Mainframes Time Bare metal (x86) Virtual machines Containers IaaS layer PaaS layer ( ) @vpetersson
17. PaaS overview Pros • Easy to use • Turnkey solution • No management Cons • Lock-in • Expensive (at scale) • Many limitations @vpetersson
18. PaaS technologies @vpetersson
19. PaaS vs. Containers • What’s the relationship between
 PaaS and containers? • Can I run Docker containers
 on a PaaS? • Will containers replace PaaS? @vpetersson
20. • Microservices • Ephemeral runtime environments • Portable and more abstraction • Self-managing systems • Host OS becomes less important • Containers are here to stay • Hybrid setups Trends @vpetersson
