The dilemma between
software development and IT operations
44

From the perspective of
software & application development
● Legacy IT infrastructure stands in the
way or is incompatible
● It is almost impossible to validate an app
for all possible infrastructure variables
and compatibilities
● It is frustrating to wait for the go-live
after development
● Apps have to be brought to the market
faster and faster
● Release cycles are becoming shorter /
more frequent deployments
● Quality and performance of an application
is becoming increasingly important
● You often have to wait for operations to
resolve issues
5

From the perspective of
IT operations & engineering
● Instead of focusing on higher quality work,
you have to manually take care of
infrastructure
● Security & compliance requirements get
more and more strict
● More pressure from development to quickly
provide suitable infrastructure
● Keeping an eye on cloud and infrastructure
costs is becoming increasingly difficult
● Fulfilling SLAs is getting harder, and
availability and performance requirements
are getting higher and higher
● The overall complexity of the IT
infrastructure is increasing, making it more
difficult to identify problems quickly
● Cumbersome recurring manual
infrastructure work
6

The result
Dev & ops departments have different goals and work in
opposite directions
77

Results
for the company
● Deadlines can not be met
● Total costs increase
● Pressure continues to increase
● Agility and flexibility are poor
● Employees work against each other and
motivation drops
● Customer satisfaction decreases and long-
term reputation can suffer
● Competitive advantages remain unused
8
How can this development be reversed?

The solution
Dev + Ops = DevOps

What is
DevOps?
Mike Dilworth, Agile and DevOps transformation lead:
DevOps is a culture, not a role! The whole company needs to be doing DevOps for it to work.

What does
DevOps have to do with cloud & containers?
● The cloud is one of the most important
developments in the tech world
● Immense benefits such as agility and
capital efficiency, whether IaaS, PaaS,
SaaS is used
● Automation, security and flexibility are in
focus
● Switching to the cloud is just the first
step: using the Cloud is also a change in
philosophy
12
All this matches with the
DevOps philosophy:
● Automate as much as possible
● Cost-effective and lean work
● Be agile to respond quickly to changing
demands
● work as a team towards a common goal

Introduction to container technology
13

What are
containers?
● Definition: Containers package an application and all the files required for
its execution into a handy package
● Unlike VMs, containers do not contain an OS or kernel
● Deploying applications gets simplified
● Container enable extensive automation of rollout processes
● Container start faster and need fewer resources
14

Benefits for your company
15

Benefits
for your company
● Simplify, accelerate and improve cloud
development
● Automate software delivery to provide
continuous value to customers
● Increase reliability, flexibility and
repeatability
● Containers make it easy to host
applications in portable environments
● Cost savings through automation
● DevOps brings together people,
processes and technologies
● DevOps enhances collaboration and
motivation
● DevOps enables collaboration between
all parts of the IT organization and the
‘continuous delivery’ of software
● Cloud, container & DevOps make your
business agile and future-proof

How do I migrate applications to the cloud?
17

5 steps of
cloud migration
1. Evaluate your technical environment and applications.
2. Educate your team and find a partner if needed.
3. Choose the right cloud platform or cloud provider.
4. Plan the migration.
5. Migrate your systems and maintain them.
18

Understand your applications
and create a migration strategy
● Understand what your applications do
and define their importance
● To become cloud-native, applications
must be modified with specific functions,
e.g. scalability
● Sort each application in terms of workload
needed for a rebuild or change
19
● Create a migration strategy per
application (live migration, host cloning,
app containerization, data migration or
virtual machine (VM) conversion)
● It's not an all-or-nothing, all-cloud native
or all-container decision

‘Companies, who want to migrate applications to the cloud, have 5 options: Rehost for
IaaS, Refactor for PaaS, Revise for IaaS ader PaaS, Rebuild for PaaS or Replace with
SaaS’ (Gartner)
“If the CIO gives the simple instruction of
'moving applications to the cloud', software
architects are faced with difficult decisions. 
 
Their decision must consider the requirements,
evaluation criteria and architectural principles
of an organization.
However, there is no perfect way: application
migration needs to be looked at from different
angles, such as the skills of IT staff, the value of
existing investments, and the application
architecture. ”
Richard Watson, Research Director bei Gartner

Application
migration paths (the x ‘Re’s’)
1. Rehost: Deploy application to other hardware environment or cloud and change infrastructure configuration.
Can be partially automated and has the advantage that architecture tweaking / modification is easier in the
cloud.
2. Refactor / Rearchitect: Execute the application on the infrastructure of a cloud provider and redefining of the
architecture with cloud-native features and possibly additional features.
3. Revise / Replatforming: Optimize or extend the existing code base to support legacy modernization
requirements and use Rehost or Refactor options to deploy the application in the cloud. Core architecture is
not changed.
4. Rebuild: Rebuilding the application architecture on PaaS, discarding the previous code.
5. Replace / Repurchase: Change to another product, usually a SaaS solution (eg: inhouse CRM → Salesforce).
6. Retire: The evaluation finds that the application is no longer needed.
7. Retain / Revisit: current status maintains (for the time being). Evaluate later or do nothing.
21

→ Concentrate on your business, the software
23
→ Focus on your customer, the development has to be faster
→ Make your company future-proof, automate and be agile
Cloud & container = agility & automation = DevOps
Summary:

Fazit
DevOps is the key
to digital transformation and for the future-
proofness of your company

Success story APPUiO & Adcubum
26

Success story
APPUiO & Adcubum
● Adcubum: leading Swiss manufacturer
of standard software for the insurance
industry
● Configuration of several applications
was very complex in the environment at
that time
● 20-year-old software adcubum SYRIUS
transferred to OpenShift using APPUiO
27
● Only work on a single platform in the
future: massive improvement of
cooperation between development and
operation and increase of efficiency
● Customers like Helsana, Concordia,
Visana and SUVA should also receive
adcubum SYRIUS in the form of
containers and operate them on their
own OpenShift installation
