Running IT-as-a-Service Part 49: The case for hybrid Cloud migration
Conclusion: Public Cloud is not the solution to all IT organisations’ technology and services problems. This is because most IT organisations use a portfolio of environments such as legacy systems, in-house and outsourced services, customised IT service management tools and standard applications (e. g. email) that cannot be all retrofitted in a public Cloud architecture without major rework. As a result, hybrid Cloud has become the preferred direction because it allows the multiple environments to co-exist in a cost-effective manner. However, a convincing business case is needed to gain business and IT senior executives’ sponsorship to adopt hybrid Cloud. While Cloud migration benefits and risk mitigation are critical success factors, the deployment-hidden cost is a major contributor to failure. The objectives of this research note are to provide a framework1 to develop the business case and to ensure its cost includes the following:
- Hybrid Cloud strategy development,
- Risks identification and mitigation,
- Go-to-market strategy, providers’ selection and contract negotiation, and
- Ongoing governance to realise the desired business benefits. This can reach up to 7 % of the yearly cost.
