Introduction to cloud migration

What is cloud migration?

It’s not just about getting there, it’s also about what you do when you get there…

What are the benefits of cloud migration?

Cloud computing: The benefits

Cloud operating model

More efficient cloud operating models are powered by analytics, automation, and AI, with a saving of approximately 30%-50% in ongoing run operations.

Easy to consume

Cloud improves agility with standardized “appliance-like” service that can be provisioned in minutes in an aaS Opex model, saving approximately 50% in start-up time.

Workload placement and optimization

Workload placement is based on transparent business parameters, saving approximately 10%-30% on cloud spend.

Secure and compliant

Security and compliance are built in at the core to protect your most business-critical workloads and most sensitive data. Read more.

How does the cloud migration process work?

What are the types of cloud migration?

Re-host (lift & shift)

This is where you shift an application from an on-premises host to a cloud service (infrastructure or platform service). Begin with the simplest items, with the fewest dependencies, low business impact, and no regulatory constraints, while moving to the most complex items as maturity increases.


You choose to migrate to an operating system version based on CNaaS Platform Standards when the application can support it, reducing the total count of enterprise supported platforms to reduce operational expense.


The company updates components of an application to conform to enterprise standards, functional needs, and security needs. This includes .Net, Java, other upgrades.

What are the challenges of cloud migration?

Legacy applications (and what to do with them)

Not every app can move easily. Which do you keep, and which do you wreck and rebuild?

Application modernization

What are your options for rebuilding applications, so they perform optimally in cloud?

Cloud management

Once you have moved your applications, what’s the best way—and who are the best people— to manage them?

Complexity of migrating

Understand the complexity you’ll face when migrating and appropriately estimate the effort to get it done.

Key dependencies

Resolve key infrastructure and application dependencies, by prioritizing applications and identifying necessary remediations helping you reduce risk, time and cost.

Business support

Buy-in from stakeholders across the business is essential for migrating at scale.

Barriers to benefits


of companies identified security and compliance risk


identified complexity of business and organizational change


identified legacy infrastructure and/or application sprawl


identified lack of cloud skills within the organization
