When it comes to legacy IT, there's life in the old dog yet. If you ask cloud proponents, these old IT infrastructures should have disappeared long ago. And yet legacy IT and mainframes are tenaciously clinging on, and companies are required to continue to host, maintain, and manage them. Where a legacy infrastructure is operated, an IT partner is needed who provides the data centers for the classic IT infrastructures.
According to the 2019 Lünendonk study “Fit for the transformation” (“Fit für die Transformation”), legacy has not outlived its usefulness yet, despite the pressure of the digital transformation. A full 13 percent of the larger medium-sized companies and corporations surveyed are not at this stage planning any legacy modernization at all, and a further 30 percent are only intending to develop a strategy for transformation over the next one to two years. Interestingly, the Lünendonk study also found that around half of the surveyed companies do not yet apply a cloud first strategy.
Companies that still rely on their legacy IT or are only just planning a successive transfer to the cloud can be provided with server, storage and backup services by T-Systems. In customer locations and the DIN/ISO 27001-certified twin-core T-Systems data centers we operate x86 servers with Linux and MS Windows and Unix servers with IBM AIX for you. The T-Systems data centers fulfill all compliance requirements under German and European data protection law and comply with all prescribed IT security standards, with 99.8 percent minimum availability.
To prepare for the future, companies need four building blocks: connectivity, cloud and IT infrastructure, security, and digitalization. However, some companies still have to rely on classic IT systems such as legacy IT. Despite the digital transformation, they still need classic hosting services.
