Design, Integration and Optimization of IT Infrastructures

The design of an infrastructure is a strategic action that aims to put in place the foundations and the basic structures of the information system of a company or a governmental institution.

It is involved in projects for integrating new user services, deploying new applications, migrating computer systems or consolidating environments.

The modeling of a technical infrastructure must meet many challenges:

  • Increase the performance of the information system,
  • Guarantee the scalability of infrastructures,
  • Ensure optimal availability of the applications and services offered,
  • Mutualize environments,
  • Securing access to architectures,
  • Control integration and administration costs,
  • Increase the quality of service.

i-CRITS sarl offers a solution covering all the key actions of the design, integration, and optimization of an IT infrastructure:

  • The audit of IT environments;
  • The study of target architectures;
  • Advice and technology watch;
  • Optimization of computer systems;
  • The definition and formalization of technical implementation specifications;
  • Drafting systems integration procedures;
  • Definition of deployment strategies;
  • Accompaniment and/or implementation of architecture migrations.

We provide our clients with all the essential assets for the success of their projects, namely:

  • A high level of expertise;
