These innovative technologies are at the heart of the microservices and DevOps revolution currently sweeping through the IT industry. They are fuelling digital transformation and accelerating cloud adoption. They're helping organisations develop infrastructure agnostic applications that can be deployed anywhere i.e. Bare Metal, Virtualised Data Centres, Private and Public Cloud. They’re helping organisations to significantly reduce infrastructure costs and accelerating agile application delivery by automating application deployments and operational management. After this talk you’ll know what these open source technologies and open standards are, what they mean to you and your organisation and where you can go to try them out.

36. Google confidential │ Do not
distribute
Google has been developing
and using containers to
manage their applications for
over 10 years.

● simplifies management
● performance isolation
● efficiency

37. Separation of concerns = operations specialization
• separate infrastructure ops from cluster ops from app ops
• deliver common cluster service
• radically reduced operations overhead
What Google gained...

38. Deeper automation = fewer bad outcomes
• higher abstraction provides more insight into behavior
• orchestration made far easier
• self-healing and self-managing systems
What Google gained...

39. Radically better physical efficiency
• containers offer efficient and fine grained resource isolation
• resource aware scheduling
• safer, less intrusive overcommitment
What Google gained...

44. INSERT DESIGNATOR, IF NEEDED44
• Open source project conceived by DotCloud/Docker Inc
• Docker, Red Hat, Google and IBM are the top contributors
• Fast paced open source project with some politics
• Fear of a single vendor lock-in has led to the creation of the Open Container Initiative (OCI)
• Red Hat is a major contributor to OCI and wants an industry standard
• Provides
• Tools to easily move container images around (Registry)
• Tools to easily run Linux Containers (Daemon and Client)
• De-facto image format
• De-facto registry format
• Relies on other projects to provide
• Linux Kernel
• Container images
• Orchestration
• Management
• Security
