Bank’s development requires solving new business tasks with the processes automation in the up-to-date IT systems. In order to assess integration of new services into the existing IT environment the intense testing of various products configurations is a must. At the moment we could model several alternative IT environments in De Novo Cloud and estimate productivity of these models in terms of ITIL and information security. Upon the multiple-aspect testing an optimized model is deployed in the productive systems of the bank. And the agile access to testing environment is crucial contrasting with obsolete practices. This speeds up the product design bringing a business initiative and a productive solution much closer. De Novo cloud services provide a highly attractive testing environment tool, that’s why we plan to extend the ongoing consume of De Novo Cloud.
