4. Devops Survey
#2013 was a good first start… It proved out the actions of high performance orgs
#2014 might not the perfect but…. it’s pretty awesome improvement in that the data is starting correlate high perf w/competitive advantage and in some
cases financial improvements
#Meta Points: (this is really good data)
##9200 vs 4000
##Empl Size = 41% in the 500 to 10k+ range
##Dept = Almost 60% are in the right place
##Servers = Roughly 60% >100 - were significant orgs
##20% are rather large orbs (>2k which would be a good indicator of enterprise)

5. Devops Survey
• Organizational Performance
• IT Performance
• Organizational Culture
• Job Satisfaction
#In summary the report kind of describes this idea of “Org Perf”
#Also points out IT Performance = Competitive Advantage (up to 2x)
##A smaller subset of the respondents volunteered co / pub traded name/ of that subset the findings were that there was a 2.5x of ones that fell into
the high IT perf categories
#Organizational Culture = IT Performance ( One of the strongest predictors of IT Perf )
##High trust,
##Cross Functional Collaboration,
##Shared Responsibilities,
##Learning Organization
#Job Satisfaction is a key indicator for Organizational Performance
#We’ve know this all along .. this is devops..
# We already know this as #devops

10. Software Defined
Everything
• Software Defined Data Center
• Software Defined Computing
• Software Defined Storage
• Software Defined Networking
#SDDC has also been referred to as Converged Infrastructure
!
# SDC -
## First order abstractions: Hypervisors on physical, then/now LXC, libContainer (containers) - Docker! - Micro-task virtualization!
## Second order abstractions are distributed clusters (Cloud, Big Data ) .. well defined API’s
!
#SDS
## First order abstractions virtualized storage hardware
## Second order abstractions ( Ceph, Swift, Swiftstack, S3).. well defined API’s (can you download the software)
!
#SDN
##First order abstractions VLAN .. again virtualizing a single box.. switch L2)
##Second order abstractions Tunnels … VXLAN… .. well defined API’s
## SDN offers further service abstractions …
### .. adding functionality into the network routing fabric for example LB (SDAS), FW (SDSec) becomes smart routing
!
# Major points…
## all three abstractions move one step away from the hardware. Second order abstractions are not directly coupled hardware.
## All three have high order programming interfaces (API’s).
#These hight order highly programable abstractions changing the landscape of IT

11. SDN is the Decoupling of Control
From the Data Plan
http://networkstatic.net
SDN is the decoupling of the control plane from the data plane... physically removing…
!
Network gear has traditionally been a black box w/coupled arch D,C,M
!
Data Plane.. packet-in packet-out .. nano second .. wire speed
Control Plane.. Local distributed brains of the network (BGP, OSPF, MPLS), How the forwarding state gets to the data place .. milliseconds/days

12. Openflow is to SDN as HTTP is to Web
http://networkstatic.net
OpenFlow is not magic, just a low level primitive with momentum for FIB programming (forwarding plane programming).
Explain the flow table...
Interesting thing this can be a device as ( a router, switch, firewall, Nat and even a Load Balancer).
... now it starts getting very interesting...
The OpenFlow Switch and Controller can communicate via the OpenFlow protocol,
!
Service chains (firewalls, Load balancers, IDS, L3 Switching)

• Disaggregation of Hardware/
Software
• X86 Compute Servers
• IP Based Storage
• Bare Metal Switches
# We saw disaggregation of compute about 15 years ago (Sun/IBM).
# ISCSI over Fiber Channel ..
# The latest and greatest is in networking… Cumulus Networks

Software Defined
Everything
# We need to start to rethink declarative and desired state infrastructure.
# We are somewhat Myopic on compute?
## It’s not just server config, packaging and vm provisioning anymore.
### How do you create declarative desired state converged infrastructure (SDE)
### Storage config, network configurations?
### Declarative Network topologies
### How are SDN flow tables declared (SDN gui’s/API abstractions). Frenetic/Pynetic
### When do we get/have converged Cloud API abstractions (e.g., a jClouds that abstracts SDC,SDS and SDN)
### What does provisioning look like for containers..
#### With things like Mesos ad Fleet the new Kubernetes)
## What is the original desired state and what is the ongoing operational state of truth .. who wins?
!
#Do our new declarations start looking more like policies.
## I need service A
### it needs n amount of nodes with x amount of cpu/mem per node.
### How is storage allocated for this service (object storage/block storage)
### Does it need virtual perimeters for Networking (VXLAN) and Security (FW) and
### How is this application service request queuing managed (LB SDAS) and also QOS
!
# infrastructure - is there a common definition of a node? Is there a single source of truth for all “nodes”
## DNS is not enough…
## Service Discovery/Mapping … go based derivatives of zookepper. Etcd/confd ..
### Consul .. someones needs to give Mitchell some Demerol and slow this kid down..

15. Composable
Infrastructure
Composability is a system design principle that deals with
the inter-relationships of components.A highly composable
system provides recombinant components that can be
selected and assembled in various combinations to satisfy
specific user requirements.

# Derek Collison (creator of CloudFoundry) says we are on the dawn of Composeable Infrastructure. Actually Google has been doing this very well of a
number of years now.
# The big difference in with things like docker containers are consumable…

• Virtualization ( 2 weeks)
• IaaS ( 2 minutes)
• PaaS ( 1 minutes)
• Containers ( 500 ms)

Composeable
Infrastructure
# How to describe docker to a friend…
!
## Very easy to install and run LXC containers…
## Docker binaries are portable across multiple visualization infrastructures.
### Truly a create once run anywhere… (BM, VBOX, Vsphere, AWS, GCE, CF)
## My personal favorite is the Git like workflow… (docker pull,push, diff commit)
### The idea is you get the image from a repo, you change it, commit and push it).
### Docker uses “copy on write file system so you can do interesting workflows…
!
#commit, diff, pull, push

# Openstack is to KVM as Mesos/Kubernetes is to Docker

## Mesos mostly developed by ex google guys who went to Twitter
