Introduction

This report is the second in a series which provides CSPs with guidance on how to migrate BSS to the cloud, including where to start, and lessons learned from the telecoms industry.

Highlights

  • Identifying those systems that should be easiest to migrate and starting with these low-hanging fruits will help CSPs gain quick wins, gain their own lessons learned, and create momentum for expanding the scope of their migration project.

Features and Benefits

  • Compare the pros and cons of different cloud migration paths for systems in the BSS domain.
  • Learn from the experiences of CSPs and vendors that have already migrated systems in the BSS to the cloud.

Key questions answered

  • What are the different migration paths to the cloud?
  • How can I determine which cloud migration path is right for my systems?

Revisiting the business impact of migrating BSS to the cloud

  • Conducting due diligence is essential to a successful migration
  • Committing to a “culture of cloud”

Determining the best migration path

  • Rehosting is the easiest path to the cloud, but not the best
  • Re-platforming can be an in-between option for those not quite ready for cloud-native
  • Re-factoring applications allows CSPs to take full advantage of cloud-native
  • Re-purchasing makes the most sense for EOL systems

Strategies for BSS migration

  • Multi-system migrations will yield better business outcomes than single system migrations
  • The most common BSS migration approach

Common roadblocks to a BSS cloud migration

  • Cloud security
  • Job security
  • The cost of cloud
  • Change management

Lessons learned from the telecoms industry

  • Lesson one: Start with the low-hanging fruit to generate momentum for the rest of the migration
  • Lesson two: Embracing out-of-the box product features lowers cost and ensures agility
  • Lesson three: Hybrid multi-cloud deployments help to mitigate concerns of vendor lock-in
  • Lesson four: Migrate the test environment to the cloud first
  • Lesson five: Path-to-production modeling can help determine if re-factoring is the right migration path
