 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

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.

Capgemini Cloud Choice

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
1. Micro-services
2. Containerization
3. Agile excellence
4. DevOps
5. Cloud
6. Platform-as-a-service

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
