About Us

Our Vision

At L3C we believe, legacy but still critical, AIX, Unix and IBM i workloads should become integral parts of cloud transformation. Their datasets should be enhanced by analytics, AI/ML and additional services building on their historical strengths. 

We migrate legacy AIX, Unix and IBM i workloads to cloud, working with our partners and clients by performing a niche but critical element in your cloud transformation initiative. We build and migrate environments to Skytap on Azure (AIX and IBM i on Azure), private, dedicated infrastructure within L3C Cloud and also to  IBM Cloud  / IBM PowerVS. Our SPARC cloud infrastructure also allows legacy SPARC/Solaris environments to be brought into digital transformation initiatives. We solve skills issues with our remote System and Oracle Database Administration services ensuring you remain cost effectively supported. 

We are independent of any vendor, enabling us to be a partner to you and recommend the optimal approach rather than be influenced by any vendor or cloud provider.
