1. Lift and shift - This is an example where systems that exist in non-Cloud environments are simply re-hosted on Cloud architecture. This move can reap financial benefits depending on the cost structure of the existing environment, but it may not be as dramatic as one would expect. The long-term advantage may more likely be that when the firm chooses to move forward to newer systems, their workloads are already on a Cloud platform that they’ve become familiar with. This is often the fastest path to the Cloud.
2. Replatform - In this scenario, the underlying workload solution isn’t swapped out, but the architecture components may have upgrades to newer versions. This can be operating system upgrades, application upgrades and increases to higher levels of availability via tools such as load balancing of services. New functionality can be implemented via this approach, without fundamentally changing the way the end users are used to running the business.
3. Replace - An off the shelf software solution that is Cloud-based may make sense when a company has outgrown the capabilities of the existing solution, or their business has changed to the point that the existing solution is no longer a fit. Given the direction of the IT industry, it is very rare that an on-premises solution would be able to compete with the advantages of running a Cloud-based solution.
4. Refactor - A firm that has needs to innovate within their market share may need to take a “refactor” approach to differentiate themselves. The innovation allowed by developing solutions that leverage Cloud-first technologies may allow the best long term financial benefit, but it requires an up-front investment and a solid commitment from the business leadership that this strategy will serve the firm’s best interest.
