In today's business, the information system has become a real vector of global strategy. Expertise and efficiency are therefore essential elements of competitiveness. This means that the business must constantly question its information system, which is not always easy when its main activity is sometimes far removed from information technology. The business therefore often resorts to Infrastructure Management. What advantages can be expected from Infrastructure Management? - The ability to concentrate or refocus on one's core business - Improving Quality of Service - Reducing and Controlling Costs: Economies of scale - Maintenance of an aging base - Seeking new skills and access to rare resources - Seeking Service IT consultants - Need to optimize a technological infrastructure - Streamline assets (e.g. servers are handed over to the Outsourcer) - Oversight of continual upgrades in hardware, OS, and software - Need to maintain the equipment at an optimum technological level - Need for user services/support, etc. - Need to secure data - Etc. While infrastructure management offers several advantages to a business, it should also be considered a solid business project. The purpose of this hub is to share experiences, risks, traps to avoid, guarantees to be required from outsourcers, the level of SLA to be required that is consistent with your activity, etc.
