In traditional enterprises, development and maintenance are often divided into two different departments.
Each is responsible for their own areas of expertise. The development department focuses on frequent delivery and development, but the operation department focuses on service reliability and efficiency. Because of the different goals of the two, there is a gap in communication and collaboration.

The CALMS are:
GCS can integrate the current CICD architecture or create a complete CICD process according to your needs, saving more time for your development and maintenance and improving more quality.
