Migrating between CSPs

Coordinated offboarding and onboarding:

• Solution, services and data offboarded from existing provider
• Onboarded to new provider

Similar to in-house to cloud migration

Unique challenges:

• Different processes
• Vendor lock-in:
  • dependent on a particular solution that not work in a different environment without significant restructuration
  • Consumer can´t leave provider (multi-year contract or high investment)

Cloud solution doesn´t consider:

• Portability
• Interoperability
• SaaS customization

Cloud-neutral approach

Vendor neutral alliances:

• OASIS CAMP for PaaS
• TOSCA for IaaS

Enhance:

• Portability
• Interoperability

Lock-in mitigation:

• Vendor selection
• Leverage portability technology
• Awareness of solution dependencies
• Contract flexibility
• Risk management

Checks for vendor lock-in:

• Proprietary systems ?
• Proprietary data models ?

Minimize inflexibility:

• Proprietary services
• Interoperability and portability
• Integration challenges
• Data ownership
• Security and privacy
• Change management

Multi-cloud tools

Avoid potential issues

Split workloads

Multi-cloud challenging to:

• Implement
• Operate

Avoid vendor lock-in:

• Informed decision-making
• Support CSP competition
• Standardized software
