Finding the right IT strategy for data center consolidation
Between On Premises, Colocation and Cloud
As soon as the objectives and milestones of the transformation project have been defined, the next fundamental decision has to be made: How do you deal with the topic of cloud? Which applications are to be "cloudified", which are to be kept "on premise" in the company's own existing IT, and which are to be outsourced to a colocation? Will the goals be achieved by renewing the existing IT or rather by merging different locations? Basically, it is always about these three options and their weighting within the IT strategy: on premises, colocation or cloud. It must be thoroughly evaluated how the focus should be placed here.
Standards and methods for successful IT transformation
Choosing one of the established cloud providers, predefined tools will get used in the implementation of the transformation project. One gives up some means of control, but at the same time one has to accept that only very marginal influence can be exerted on the process itself. With non-cloud solutions, the situation is completely different. There are no limits to customization. Here, various tools, such as SWOT analyses, checklists from the BSI (German Federal Office for Information Security) or TÜVit's own criteria catalog TSI.STANDARD (Trusted Site Infrastructure) can be used and applied as a guide. Especially for critical infrastructures, the numerous serious acceptance criteria are decisive. For example, in order to adequately meet the challenges that have to be overcome during migration or when planning a new data center or server room, an analysis of the requirements according to KRITIS, including the industry-specific security standards (B3S) and the corresponding standards such as ISO 27799, is indispensable. When information technology is renewed and relocated, the primary difficulty is to ensure the relocation of a highly complex, sensitive system without data loss, while avoiding or managing downtime in a controlled manner.
Hyperconvergence as a success factor for hybrid models
To ensure that the flexibility to move freely between the three options of on premises, colocation and cloud is still available after the IT transformation, interoperability between the different systems should be a particular focus of the project. Keyword: hyperconvergence. In a hyperconverged system, computing, storage, networking and virtualization resources are combined into a software-defined unit and managed as a single application. One great advantage of this is that complex infrastructures can be centralized, thereby reducing interfaces, eliminating inefficiencies, and increasing computing power. In the orchestration of container systems, for example, the open source system Kubernetes has established itself as an important standard.
