Tenet #1 - DevOps

9

DevOps seeks to solve this

It's not my machines, it's your code!

It's not my code, it's your machines!


Ongoing Operations is Now a Shared ResponsibilityIn perpetuity. No more “throwing it over the wall”

New GoalAdd new features and keep the system stable, fast and available

DevelopersPaid to add new features

that may break things

OperationsPaid to keep system

available, stable, and fast

Copyright © 2017, Oracle and/or its affiliates. All rights reserved. | 11

New goal:Deliver new features and keep the system stable and fast. Get structured feedback data !!!


Prerequisite #1 - DevOpsRequires changes throughout your entire organization

Culture Technology

Respect

Discuss

Avoid Blaming

“Done” Means Released

Infra as Code

Shared Version Control

One Step Build/Deploy

Don’t Fix Anything

• Dev respect for ops• Ops respect for dev

• Ops should be in dev discussions• Dev should be in ops discussions• Shared runbooks

• No fingerpointing!• Everyone should have some

culpability

• Dev’s responsibility shouldn’t ever end – production support required

• “Throwing it over the wall” is dead

• Don’t build envs by hand• Scripts checked in and

managed as src

• Single system• Ship trunk• Enable features through flags

• One button build/deploy• If verification fails, stop and

alert or take action

• If something breaks, re-deploy. Don’t fix

• Fix environment setup scripts


Tenet #2: Consume Things as a ServiceRequires fundamental shift in how applications are built

Single Deployment

Three Key Rules to Microservices

Don’t share a datasource across microservices

Can release each microservice independently

Can build a microservice independently


Everyone Should Be Able to Build Anything At Any Time

• Manual one button build/deploy

• Scheduled builds - every day, every week, etc

• Builds triggered by code check ins

• If post-build validation fails, report it

Set it and forget it


Stop Manually Fixing ProblemsIn no case should an administrator fix issues by hand. Should be 100% automated

Auto-scaling will automatically launch a new container on new hardware as load dictates

Hardware FailureExample: motherboard failed

Auto-scaling will automatically launch new containers as load dictates

Network FailureExample: switch failed

Health checking should fail and the container will be culled. Auto-scaling will automatically launch a new container as load dictates

System Software FailureExample: kernel panic

Application Software FailureExample: bad file permissions

Fix the source (your application, your container, your Dockerfile, etc) and re-deploy your entire application


Owners Support in Production

Everything is Owned by a Small Team

Owners Implement

Owners Architect

Owners Care

Owners Can Fix Things

Ownership is Key to the Success of Cloud NativeIn traditional enterprises, any one individual has very low ownership of anything. It’s classic tragedy of the commons


Do One Thing and Do It Well

Focus on Business Capabilities

Avoid Inter-dependencies

Start Managing Small, Vertical TeamsCan have hundreds of microservices for a larger application

Large

Medium

Small

11-15 PeopleExample: Order Microservice

4-10 PeopleExample: Inventory Microservice

1-3 PeopleExample: Order Status Microservice


Remove All Hard-coded IPs, Host Names, etc

20

Use service discovery, DNS, etc instead. Everything should be dynamic


Teams Should Not Have 100% Freedom

Standardize where it makes sense. Be pragmatic

Why Containers?

22

• Quickly create ready-to-run packaged applications, low cost deployment and replay

• Automate testing, integration, packaging

• Reduce / eliminate platform compatibility issues (“It works in dev!”)

• Support next gen applications (microservices)

• Improve speed and frequency of releases, reliability of deployments

• Makes app lifecycle efficient, consistent and repeatable – configure once, run many times

• Eliminate environment inconsistencies between development, test, production

• Improve production application resiliency and scale out / in on demand

A container is packaged as an entire runtime environment:the service/app plus all dependencies, libraries, & configuration files needed to run it

Portable across environments & lightweight (share the OS)

Developers care because: IT cares because:


Virtual Machines vs. Containers

Virtual Machines● Each virtual machine (VM)

includes the app, the necessary binaries and libraries and an entire guest operating system

Containers● Containers include the app & all of its dependencies,

but share the kernel with other containers. ● Run as an isolated process in userspace on the host OS● Not tied to any specific infrastructure – containers run

on any computer, infrastructure and cloud.

Containers

Docker Architecture

24

• Client – Command line interface (CLI) for communicating with the host

• Daemon – server process that manages Docker objects

• Image – hierarchy of files build by docker

• Container- runnable instance of an image

• Registry – external storage for Images

Support for Docker Running on Oracle Linux (Doc ID 1921163.1)• Oracle support is limited to the version of Docker built by and downloaded from Oracle.

Support is not provided for the upstream binary packages downloaded from the upstream Docker site.

• Oracle support for Docker is limited to customers with either Basic or Premier Oracle Linux Support Subscriptions.

• Oracle only provides Docker server binary packages for Oracle Linux 6 and Oracle Linux 7 (x86_64). Oracle only provides support for Docker with the Unbreakable Enterprise Kernel Release 4 (UEK4), identified by a kernel version of "4.1" or newer.

• Oracle support is limited to severity 2 service requests and lower. Severity 1 service requests will not be accepted for Docker.

• Support is limited to assistance with the initial installation of Docker and subsequent configuration of Docker to enable downloading, creation and running of Dockerizedapplications.

42


Support for Oracle Database Running on Docker (Doc ID 2216342.1)

• Oracle plans to certify the latest versions of Oracle Database to run in Docker containers which are built and supported with Oracle Linux and UEK4 as the host.

• Additionally, Oracle will support customers running Oracle Database (single instance) in Docker containers running on Oracle Linux 7 or Red Hat Enterprise Linux 7. Docker binaries are available in the Addons channel for Oracle Linux. Details on Installation can be found in Chapter 2 of the Oracle Linux Docker Users Guide.

• Oracle Database running in a Real Application Clusters (RAC) configuration in Docker containers is NOT supported.

UPDATE (August ‘17): Oracle RAC for Docker early adaptors announced
