2. Networking Storage Servers Virtualization O/S Runtime Middleware Data Applications / Code Back to basics : The IT Stack
3. Networking Storage Servers Virtualization O/S Runtime Middleware Data Applications Traditional On-Premises Software as a Service (SaaS) Networking Storage Servers Virtualization O/S Runtime Middleware Data Applications / Code Managed by provider Managed internally

6. Malcolm McLean - 1937 Intermodal Shipping Containers Standardized Building Block 90% Decrease in Costs Flexibility Portability Efficiency Revolutionized International Trade Open Source (Apache) - 2013 OS-level Virtualization Containers Standardized Building Block 48% Decrease in Costs Flexibility Portability Efficiency Revolutionizing IT IT is being transformed by Containers driven by agility and economics
7. Why it works? Separation of concerns Deb - The Developer Mike - The Ops Guy Worries about what’s « inside » the container • Her code • Her libraries • Her Package Manager • Her Apps • Her Data To her, all Linux servers look the same Worries about what’s « outside » the container • Logging • Remote access • Monitoring • Network config All containers start, stop, copy, attach, migrate… the exact same way
8. Why so much interest in Containers? #1 : Application Portability Isolated containers package the application, dependencies and configurations together. These containers can then seamlessly move across environments and infrastructures. #2 : Ship More Software Accelerate development & deployment, CI and CD pipelines by eliminating headaches of setting up environments and dealing with differences between environments. On average, containers users ship software 7X more frequently. #3 : Resource Efficiency Lightweight containers run on a single machine and share the same OS kernel while images are layered file systems sharing common files to make efficient use of RAM and disk and start instantly.
9. Docker uses a copy-on-write (union) filesystem New files(& edits) are only visible to current/above layers Layers allow for reuse • More containers per host • Faster start-up/download time – base layers are "cached" Images • Tarball of layers (each layer is a tarball) Filesystem Base OS / Kernel Fedora Ubuntu tomcat tomcat liberty CNTR1 CNTR2 CNTR3 CNTR4 app1 app2 app4 app3 Layer Layer Layer A technical view into the shared and layered file systems technology Containers
10. Why do you need Container Orchestration? VS. Pets Cattle
11. What is Kubernetes ? “Kubernetes is an open-source platform for automating deployment, scaling, and management of containerized applications across clusters of nodes”
12. Kubernetes – Simplified architecture
13. Kubernetes Capabilities
14. A few Kubernetes companions (based on Open Technologies) Container Orchestration Kubernetes Infra. as Code Image Registry Infrastructure Language Runtimes (NodeJS/Java/Python) Monitoring DevOps Tools Logging Service Mesh Package Manager
17. A production Kubernetes environment is at last 50 Components https://www.ibm.com/support/knowledgecenter/en/SSBS6K_3.2.0/getting_started/components.html
18. Do you want to build it yourself?
