When considering migrating data centers to IaaS, organizations must select one of three options. The choice will depend on the end goal of the migration, as well as individual organization needs.
Option No. 1: Lift-and-shift
Lift-and-shift means that workloads are migrated to cloud IaaS in as unchanged a manner as possible, and change is done only when absolutely necessary. IT operations management tools from the existing data center are deployed into the cloud environment largely unmodified. Little or no use is made of cloud-native features. This is a straightforward option, but generally results in little created value. Plus, it can be a more expensive option and does not deliver immediate cost savings.
Option No. 2: Cloud-enabled virtual automation
IT processes are modified in this approach to take advantage of automation and some cloud-native capabilities. The migration process is used to make adjustments to drive greater standardization, automation and a cleanup of existing operations. Workloads are “sanitized” during migration to ensure they are resilient, secure and cost-efficient. This might be a good fit for an organization looking to avoid running its own data center or implement innovative technology more quickly.
Option No. 3: A DevOps transformation
IT and some business processes are transformed, and a cloud-native agile approach is used as much as possible during the migration. Cloud-native, Dev-Ops-oriented tools are used throughout the entire application life cycle, with a strong emphasis on automation and “infrastructure as code.” This approach will renovate the technology core of the company to support Mode 2 and Mode 1 needs. This is the most beneficial option, but a full transformation is difficult, disruptive and complex. It is a good option for enterprises looking to add agility and DevOps across the entire IT organization, and not just to Mode 2.
