Le data lineage et l’usage des données pour transformer un système : simplifications / migrations

      Take back control of your Cobol assets / migrate      Cobol, the symbol of "IT debt"     The "Cobol" teams are being reduced The oldest part of information systems ("legacy system") is in the hands of a population of specialists whose number continues to shrink. This is the case of Cobol specialists. And these teams are often overwhelmed with requests.   The decommissioning of Cobol is constantly postponed Rather than removing or transforming the oldest technical layers, typically the Cobol layer, companies have piled them on so as not to take any risks. It is also true that the Cobol has acquitted itself well of its mission so far! Thus in many companies, the problem has been circumvented at the start of the most recent technologies, to adapt and manage the old data formats ("ascending compatibility"). This for a very long time now.   But this state of affairs is not irremediable. We will have to start by "opening up" the system,

      Reprendre le contrôle de son patrimoine Cobol /migrer     Le Cobol, le symbole de  la "dette IT"      Les équipes des "Cobolistes" se réduisent La partie la plus ancienne des systèmes d’information ("legacy system"), est aux mains d’une population de spécialistes dont le nombre ne cesse de se resserrer.  C'est le cas des Cobolistes. Et ces équipes sont souvent submergées de demandes.    Le décommissionnement de Cobol est sans cesse repoussé Plutôt que d'avoir supprimé ou transformé des couches techniques les plus anciennes, typiquement la couche Cobol, les entreprises les ont empilées pour ne pas prendre de risque. Il est vrai aussi que le Cobol s'est bien acquitté de sa mission jusqu'à ce jour ! Ainsi dans beaucoup d'entreprises, on a contourné le problème au départ des technologies les plus récentes, pour adapter et gérer les formats de données anciens ("compatibilité ascendante"). Ce depuis très longtemps maintenant. 

    FinOps : Reduce Cloud Costs by Removing "Dead Branches"!   Data lineage and analysis of the uses of information to calculate the cost of "living branches" and "dead branches". For simple and cheaper cloud systems.      Intro  Cloud costs, a real subject!   ____________________________________     OWe are not going to dwell on the adoption of the Cloud, but we will note that 50% of companies have 100% of their infrastructure in the Cloud (Rackspace Technology 2022, in association with Google Cloud), and the others are thinking about it seriously: end of infrastructure to manage, infinite scalability, often lower costs, etc. The strengths of the Cloud are also its limits: the systems are ultra-scalable, and the teams have a field day for the greatest benefit of the business. It is also unfortunately the realm of informational inflation that is not always justified, with strong impacts: 7 out of 10 companies do not know exactly what they are spending thei
