Nowadays, consumer expectations have been revolutionized by instant access to services and information. Your IT infrastructure, the foundation of your business, must be agile and ready to adapt quickly to constant innovation. These objectives must be combined with performance, security and data regulation issues.

This is why the Global Cloud Operations department, which carries the Cloud & Security and performance offer of the Castelis group, proposes a suite of services that respond to a large part of these challenges.

Classic remote managed services

Securing on-premise infrastructures

At Castelis, we are Cloud first. However, we understand that not all infrastructures can be found in the Cloud and many customers keep a small local infrastructure allowing them to host local file shares, badge servers, video surveillance, Active Directory or other.

Our teams are also trained on VMWare as well as HyperV to control these local infrastructures remotely, monitor their proper functioning, ensure the proper monitoring of backups, set up delocalized backups on the Cloud and ensure the security of this on-prem infrastructure.

We work hand in hand with your local teams to coordinate with them the management of physical problems on site that require their intervention.

We offer 24/7 monitoring of these local infrastructures for a fraction of the cost of a dedicated team, freeing up your local team’s time and resources.
