Productivity Paradox

16

having more technology for the sake of technology adds a

productivity paradox which makes things more complex

#UKVMUG

Simplicity

17

reset

drive simplicity everywhere

get stuff out of the way

modularise and simplify it

sell as business/digital/whatever transformation

#UKVMUG

Why Cloud?

18

finding efficiencies in delivering services to end users

drive simplicity

using automation, orchestration & security

#UKVMUG19

Cloud

Fog

Multi-Cloud

#UKVMUG21

State of the Cloud Report

https://www.rightscale.com/lp/state-of-the-cloud

Enterprises Want Multi-Cloud Strategy

More Use of Hybrid/Private Cloud

Average Number of Clouds Used = 3 public, 3 private

Large-Scale Cloud Use Increases

Security Is No Longer #1 Challenge

#1 challenge = Lack of resources / experience

DevOps Tools Gain In Popularity

Public Cloud Adoption - AWS then Azure then ….

#UKVMUG

Vested interests

22

people invested in public cloud drive public cloud message

people invested in private cloud drive private cloud message

time to let common sense prevail

#UKVMUG

What is multi-cloud?

23

applications deployed across

two or more cloud platforms

mix of SaaS, PaaS, IaaS

Private Clouds Public Clouds

vSphere AWS

Hyper-V Azure

OpenStack vCloud Air

Dedicated Server OpenStack

#UKVMUG

Why multi-cloud?

24

already happening whether you want to or not

business unit individual needs

shadow IT

busting shadow IT can kill innovation

#UKVMUG

Multi-cloud advantages?

25

best cloud for each workload

native capability

agility

reduced vendor lock-in

price control

disaster protection

#UKVMUG

Multi-cloud disadvantages?

26

complexity

multi-cloud expertise

design + support

different vendors/APIs/constructs

integration between clouds

billing

tracking what's where

multiple security

#UKVMUG

What? Where?

27

what to create/write/build/design yourself

what to buy/get/download/use

what to outsource/consume/SaaS

Bimodal IT

37

guard the old - traditional

invest in the new - innovative

production = legacy

always work on transition

embrace legacy

discipline to pay down technical debt

#UKVMUG

Undifferentiated Heavy Lifting

38

tools, systems, and processes which do not

improve the unique value of your organisation

This doesn’t matter

#UKVMUG

Don’t reinvent the wheel

40

don't create what you can buy/get/download

don't buy/get/download what you can consume

avoid customising

avoid provisioning infrastructure

#UKVMUG

Superficial Private Cloud

49

focus on mainly legacy apps

shunting VMs at an IaaS layer between clouds

private cloud is hard!

20,000 out of 500,000 customers use vRealize Suite

only 4% of customers using VMware’s private cloud product!

maybe don’t migrate

use cloud to build new things

#UKVMUG

Cloud -> DevOps

50

not just app developers

infrastructure as code

configuration management

policy based repeatable deployment & management with built-in auditing, security

using automated toolshttp://www.aktiom.net/services/cloud-and-infrastructure/

#UKVMUG

Infrastructure as Code

51

reusable content

security built-in

shareable

inner-sourcing

human design

machine operated

#UKVMUG52

“All software will be installed, configured and managed by other software”

#UKVMUG

Infrastructure as Code

53

“or rather spend your efforts cleaning-up messes that a well-trained monkey could be

doing”

#UKVMUG

Infrastructure DevOps

54

don’t write code

be agile for building your cloud

create a partnership with pilot teams

bust the silos

MVP, small iteration, no tada cloud!

Monoliths vs. Microservices

64

#UKVMUG

Microservices ≈ Containers

65

small and focus on doing one thing well

containers are infrastructure as code: Dockerfile

containers are built by process not installed

multi-cloud

Automation & APIs

78

RESTful APIs

PowerCLI on Linux/Mac

don't code if you don't have to

don't automate the wrong process.

can't automate what you don't understand

process improvement means understanding the process

business critical processes

Security

max security = remove humans from process

infrastructure as code = great for security

config/patch/password management

82

explore multiple cloudsAWS / Azure

read “The Phoenix Project”

learn source controlGitHub

tinker with config mgmtPuppet, Ansible, Chef, Salt

play with Docker

#UKVMUG

Take-aways

83

reset on simplicity

map your IT

embrace multi-cloud

play with AWS / Azure

place intelligently

look at hyper-converged

infrastructure as DevOps code

play with Docker/containers

have fun learning
