So how does this differ?



Why Cloud Native?



Strong governance and control

Test & measure exhaustively

Map everything to requirements

Restrain change, slow down

What is being asked of Enterprise IT is the at odds

with how Enterprise IT has often been operated over recent years

Disconnect

Fast & Easy to Change

Innovative: Try & Adapt

Flexible, adaptable, scalable

Business Aligned

Evolving with the Business

Enabling market disruption

Facilitate Agility & Speed

What IT Needs to be

Contain / Reduce Costs

Ensure stability of existing IT

Manage Legacy / Obsolescence

Keep the Lights On

IT Commitments

this implies

A massive transformation is required!



The need for speed & agility is being driven by

several factors that have become the new normal

Better User Experience

Users

exist online.

They carry

their digital selves.

Companies keep

upping the game.

They’ve receive

personal service.

Personal service

is the expectation.

All of this implies…

Every company is now a customer company Every company is now a software company1 2

Every company needs “Google like” application delivery speed and agility3

“In short, software is eating the world.”

- Marc Andreessen



Advantages

• Ignorance of the historical “way it’s done”

• No organizational / cultural inertia

• No technical / legacy debt

• Smaller, simpler products – to begin with…

• Powerful new software frameworks

• Enterprise grade elastic software platforms

• New methods, ways of working, culture

Responding to these needs is natural for

companies that are Born in the Cloud

Cloud Native Companies

What is Cloud Native?



What are Cloud Native companies doing differently to improve IT agility,

improve time-to-market and reduce system costs?

Continuous Delivery Automation, Continuous Deployment

Hybrid Cloud (public / private, multiple public clouds…)

Software Defined Everything – SDI, SDN, SDS…

Dynamic Infrastructure, Blue/Green deployments…

Automated Provisioning & Deployment

New Generation Software Frameworks

Agile, BDD

Immutable Infrastructure, Containers…

Hybrid Architectures (IaaS, PaaS, SaaS…)

Cloud Elasticity, Auto-scaling, Machine Recycling, rolling updates…

Microservices Architectures & Elastic Enterprise Platforms…

…

These can be used independently but are complementary and when used all

together, they provide the ideal context for delivering solutions at Cloud speed.

We will collectively call this “Cloud Native” application delivery.

Cloud Native Apps: Our Approach



How to Build More Agility = Speed + Adaptability

From

• Waterfall development

• Months to procure, weeks to provision,

days to update and refresh

• Major, long-duration releases

• Static resources

• Limited change windows

• Manual scaling

• Managed # of users

Most IT shops are optimized for “yesterday’s”

application landscape…….

• Extreme Agile development

• More frequent, smaller releases and updates

• Fast builds and deployments

• Instant feedback loops

• Dynamic and horizontal scaling

• No planned downtime

• Always on and connected

• Millions of users via multi-channels

Optimizing for continuous and

rapid innovation

To



Key capabilities to enable:

Our Agility offer is focused on transforming

how a client delivers software

• Adopting more loosely coupled,

fine-grained architectures

• More frequent, smaller releases

• High degree of re-use and portability

• Easier to debug and enhance with

code traceability and app feedbacks

(log analytics, A/B testing)

• Enabling developer self-service in

builds and deployments

• Developer abstraction

from technology stack, infrastructure,

and operations

Increase developer productivity

• Automation of build, deploy and

environment management

• Auto-provisioning

• Quick restarts and refreshes

• Dynamic horizontal and vertical scaling

• Minimal environment disruption for

patches and maintenance

• Environment and deployment

consistency

• Self-healing resiliency

Remove operational roadblocks

• Practice Agile excellence

• Embrace 12-factor app development

principles

• Continuous everything: integration,

testing, delivery, deployment

• Rigorous traceability from

requirements, tasks, code, builds,

tests, packages & deployments

• Rapid rollbacks, canary style

blue/green deployments, testing in

production

• Instant and insightful feedback,

A/B testing

Change the way you deliver

Understanding Application Lifecycles for Cloud Native

0. Define what is required

1. Deliver a version of business application

2. Provision, deploy and validate the Business App

(including infra & middleware) to various

environments (INT/VAL/PROD)

3. Notify operations of components deployed and

and activate ops services / SLA required

4. Operate Business App components

(supervision, patching, and other operations)

5. Provide functionality / value to business

6. Provide support and report SLA to business

Rinse & Repeat…



Dev/Ops is orthogonal to App/Infra

Dev

(E2E, Infra,

m/w, Apps)

Delivery

(E2E, Infra, m/w, Apps)

Business App

(E2E, Infra, m/w, Apps)

Ops

(E2E, Infra,

m/w, Apps)

Cloud Native

• Need Infra Dev and Ops

• Infra becomes less about H/W and more

about S/W

• Infra people need to learn dev. E.g. SDI

with chef or puppet and infrastructure

creation with ARM templates or

CloudFormation

• Need Apps Dev and Ops

• Apps becomes less about delivering to

Ops and more about value in production

• Apps people needs to know why their

apps become slow, fail or get hacked.

• Infra dev is quite different from app dev, even

wrt common used languages, though there are

some common principles and best practices



WoW, Platforms & Tools - Dev

Traditional

• IT driven, Value defined by specifications.

• Success defined by meeting milestones.

• Focus on delivering to scedule and budget.

• Waterfall principles with clear project phases

and detailed planning schedules.

• Customer represented indirectly by business

representatives at specification and

acceptance. Very slow production feedback

from real users.

Cloud Native

• Business Driven, Value defined by business

impact.

• Success defined by velocity of putting value in

production and by business metrics

dashboards.

• Focus on delivering value as quickly and cost

effectively as possible, prioritizing work by these

criteria.

• Agile / Lean principles, mixing batch oriented

models such as SCRUM and pull oriented

models such as KANBAN. Voice of the

customer required throughout the lifecycle.

• Continuous Integration and Continuous Delivery

essential.

Dev



WoW, Platforms & Tools - Delivery

Delivery

Traditional

Infrastructure to support mostly manual

provision, deploy and test processes

• Outlook, Word, Excel

• CMDB & Planning Tools

• Test planning and report tools

Ops define constraints and certain procedures.

Dev define solution specific procedures and

throws over the wall.

Ops executes procedures…

Cloud Native

Infra, Platform & Tools to

provision, deploy and test automatically

• Provision and deploy tools:

• Chef, Puppet, Ansible, Salt…

• Cloud templates (ARM, CloudFormation, Heat…)

• Docker Compose/Swarm, Mesos, Kubernetes…

• Test automation tools

• Selenium, MTM, HPALM, Gatling, Simian Army…

Collaboration required on automation scripts

between Dev&Ops, Apps&Infra



Infra & Platforms – Business App Hosting

Business App

Traditional

• Static Infra with long life requiring care

• Limited supervision, mostly technical

• Users and hackers find / report most

latent problems

Cloud Native

• Dynamic Infra allowing auto-scaling, rolling

updates, blue/green deployments…

• Tendency towards short-lived, commodity,

immutable infrastructure + services

• Technical and business health supervision

• User perspective SLA monitoring

• Testing in production (e.g. Simian Army)



WoW, Platforms & Tools - Ops

Ops

Traditional

Operation of static Business App platform as

defined at Delivery

• Security, Health & Performance Supervision

o H/W, Network, OS, middleware, app

• Problem investigation, solving and routing…

• Patching, Antivirus updates, Disk clean-up…

Cloud Native

Services largely the same as traditional but needs to

work with automated deployments and dynamic

infrastructure, and be more complete (see previous

slide).

How to know what to supervise with what SLA? How to

distinguish between Dev, Val & Prod? If Prod is down

during an upgrade with planned downtime, this should

not create alerts.

Configuration of operations should be automated as

part of delivery platform

Collaboration required on automation scripts

between Dev&Ops

Workaround: Operations defines constraints &

prerequisites (supported and validated configurations

including OS & middleware components with required

agents and registration requirements) => Attn: RACI
