1. Companies are realizing that moving to the cloud is inevitable and need to determine their cloud strategy by assessing which applications are cloud-feasible and the best deployment model.
2. Determining cloud feasibility involves analyzing factors like the application's criticality, dependencies, and technical compatibility with cloud platforms. Feasible applications then need deeper analysis to identify the optimal migration path.
3. Developing an effective cloud strategy requires structuring large migrations, defining target architectures and operating models, and taking a thoughtful approach to planning the identification, movement, and management of applications in the cloud.

Making the Journey_ 7 Essential Steps to Cloud Adoption.pdfAnil
Cloud adoption can be a transformative journey for businesses, offering scalability, agility, and cost-efficiency. Here are seven essential steps to successfully adopt cloud technology
The cloud can be considered the software and services that reside and operate over the internet rather than an on-premise network of servers. There are many things enterprises must do to facilitate a smooth migration to the cloud. To adapt to the cloud, they have to improve the scalability of internet-based database capabilities while reducing the cost of risk.
Moving to the cloud not only helps reduce costs but also imparts flexibility and scalability to the organisation. Adding an extra server requires capital expenditure, while dynamically changing requirements like this can be considered operating expenses. Despite these advantages, the cost might still be too high for it to matter so go over every aspect that can or will be impacted.
Cloud migration: It is a process of moving your organization’s infrastructure over to the cloud environment. If you will read this blog, you will find everything that an organization should understand about cloud migration before planning for the big shift.

2. Leveraging the
value of Cloud
Companies are realizing that the Cloud is an inevitable part of
their future — not a question of “if” but rather “when,” “where,”
“what extent,” and “how”. For some companies, it may be a
key enabler to reduce IT cost while improving responsiveness
to the business. For other companies, it may be niche play,
focusing Cloud on pre-production environments or as more
cost-effective disaster recovery or backup option. Others
would use it, in conjunction with DevOps and Platform-as-
a-Service (PaaS) solutions, to enhance IT agility, enabling
quicker releases and responsive innovation. And, a bold
few may make it an integral part of their business enabling
strategic capabilities that disrupt industries; case in point
companies include Uber, Airbnb, and Netflix. Regardless of
intent, determining what makes sense to move to the Cloud is
a key IT imperative today.
Defining the Right Cloud Strategy
Determining the right Cloud strategy entails answering the
following questions about an application:
1. Whether it’s Cloud-feasible or it stays on premise
2. If it’s Cloud feasible—
–– Should it be on a public or private Cloud
–– Which Cloud option makes sense – Infrastructure-
as-a-Service (IaaS), Platform-as-a-Service (PaaS) or
Software-as-a-Service (SaaS), makes sense
In answering these questions, there are a multitude of
business and technical factors to consider. First, there are
factors that help answer the first question and determine if an
application is even viable for the Cloud:
• A Tier 1, mission critical, or difficult-to-virtualize application
may not be good candidates for the Cloud.
• An application that has a heavy client component or near
real-time device integration, is not Cloud-feasible.
• Applications that are close to end-of-life-cycle, lack
documentation or access to the source code are not
ideal candidates.
Another key factor of Cloud feasibility is the technical
compatibility of an application to the technology stack of a
public or private Cloud platform. A legacy application that is
tightly integrated to OS/400 or an older Solaris version will
be cost-prohibitive to migrate to the Cloud, unless a rewrite
is warranted.
Also, there are a number of factors to consider that bolsters or
diminishes the case for Cloud. Some examples:
• How complex is the application? How many integrations
and dependencies does it have? What is the network
pattern and latency of these dependencies?
• Does the application have unpredictable demand or
transaction volume?
• Will the application require significant change or
enhancements in the next 12-18 months?
At the end of this first step, one would have a better sense
if an application were Cloud-feasible. Doing this requires a
structured, logical approach that does not result in analysis
paralysis. The intent of this brief is to describe a proven
approach that has been built over experience.
Once the applications are deemed Cloud-feasible, the next
step involves determining the correct Cloud pattern: public
versus private; IaaS, PaaS and/or SaaS. Consideration factors
for private Cloud versus public Cloud include:
• Data, security, and compliance policy and requirements:
a private Cloud can potentially provide a more secure and
compliant platform
• Higher performance, availability, or technology stack
concerns: a private Cloud enables a company to have
more control to design the right hosting platform for
an application
• Cost: a public Cloud, being multi-tenant, has economies
of scale
Determining the appropriate Cloud option, IaaS, PaaS or
SaaS, revolves around the characteristics of the applications
and desired business or IT outcomes. If an application is a
custom digital asset it can immensely benefit from PaaS. An
application that has significant functional gaps and is in an
established domain area like CRM, HR, or supply chain, a
SaaS solution may be the better play. Or, if application is fairly
stable and virtualized, simply re-hosting it on the Cloud, IaaS,
makes perfect sense.
There are many factors to think about which can easily
result into analysis and paralysis. A recommended approach
is to determine which ones are most applicable given the
company’s intent, the applications to be assessed, and the
IT context. Typically this results in looking at a dozen factors.

4. Deciding to Move or Not
Once you’ve determined an application is Cloud viable,
the next step is to determine if it makes sense to make the
move. In this regard, a deeper discovery and analysis of
the application is needed. More specifically, the following
information is required:
• Architecture, configuration, usage profile, metadata
• Integration and dependency mapping
• Data rate of change (gravity)
• OS or app licensing provisions and updates needed
• Privacy, security, and compliance requirements
• Identity and user access management requirements
• Infrastructure requirements — storage, network, disaster
recovery, backup, performance, availability
• Financials
With this additional information, the right migration pattern can
be determined.
In some instances, applications can be retired and/or
consolidated with another application. If migration is the next
step, the application may need to be re-hosted, remediated, or
re-platformed:
• Re-host: this is most appropriate for applications that are
virtualized and has a technology stack that Cloud supports
in its entirety
• Remediate: to move and take advantage of the Cloud, the
application code and architecture may need to be changed
and this can range from low to high degree of change
• Re-platform: this is best when re-architecting and major
code re-write are needed to not just move but also optimize
(“cloudify”) an application to run on the Cloud
Knowing the migration pattern can help gauge the amount
of time, effort, and cost to move the application. Having
this information, balanced with the potential benefits of the
Cloud will provide the business case to move to the Cloud
or not. Also, the application lifecycle benefits (e.g. quicker
development time) and opportunity costs of not moving to
Cloud (e.g. lack of elasticity/scalability and configuration
flexibility) need to be considered as well.

Planning the Move to the Cloud
with Eyes Wide Open
Migrating a few applications to the Cloud, unless they are
highly complex, tends to be a straightforward undertaking.
However, when more applications are involved (beyond
30+ applications), logically structuring and sequencing the
migration becomes very important. Structuring involves
grouping the applications in clusters or tranches. This may be
driven by domain area, technology, common dependencies
and integration, or balancing complexity and risk. Sequencing
the clusters may be defined based on expected return and
implementation effort.
As more applications are moved to the Cloud, defining the
right architecture and operating model becomes a critical step
in the migration plan.
In architecting the Cloud platform, there are three areas to
think through. First, is defining and provisioning the right Cloud
environment for each application. This requires understanding
the hosting requirements of the application thoroughly. It
results in defining the key aspects of the Cloud environment
including:
• Functional mapping of Cloud platform stack
• Topology pattern
• Data and storage management approach
• Networking approach
• Security, privacy, and compliance design
• Provisioning specifications
Second, is choosing the right Cloud services the applications
need. These services may be part of the Cloud platform, user-
defined, or open sourced. Typical services include:
• Identity and access management
• Integration
• Database (mySQL, noSQL)
• Data storage and back-up
• Messaging
• Mobile, media, web, IoT
• HADOOP, Analytics, HPC
Orchestration and brokering these services also needs to be
defined so applications can easily identify, bind, ingest, and be
managed by the services. Making services “plug and play” will
allow flexibility in ensuring best-of-breed services are offered.
Having common services across application and workloads
is also important to making the Cloud more manageable and
supportable.
Third, is ensuring the Cloud environment is well architected
overall. In achieving well architected, the diagram below
outlines the key areas to think through:
Defining the Cloud operating model entails design of how the
applications in the Cloud will be developed, managed, and

5. supported. With the Cloud and adoption of DevOps, there’s
significant opportunity to enhance IT agility and quality in
developing software. Infrastructure as a code can become
a reality using tools like Puppet and Chef. Provisioning and
deploying environments can be more automated, reducing
responsiveness from weeks to days or even hours. In addition,
managing and supporting applications in the Cloud require
transformation of ITSM and ALM processes to ensure
applications are delivered reliably and securely. New Cloud
monitoring tools are needed. IT service catalog has to be
updated to include different application deployment patterns
and associate Cloud environment images. Provisioning Cloud
environment can also be done through self-service. Finally,
new Cloud roles may need to be defined and created.

Capgemini offers an end-to-end approach in helping
companies strategize and plan their move to the Cloud. Our
approach starts by determining whether the applications are
suitable for the Cloud and if so, what is the appropriate Cloud
pattern: private or public, and IaaS, PaaS or SaaS. Next,
a deeper application discovery is needed to determine the
appropriate migration pattern to an IaaS or PaaS. This will
help assess the effort needed and confirm the business case
for migrating. Third, a roadmap needs to be defined when a
significant number of applications are viable to be migrated.
Finally, before executing the migration, appropriate thinking is
needed in defining and refining the desired Cloud architecture
and operating model.
Summary
Moving to the Cloud requires a thoughtful, deliberate, and structured approach.
