About Us

Our Vision

At L3C we help complete our clients’ and partners’ digital transformations by migrating legacy AIX, Unix and IBM i workloads to cloud. We migrate AIX (and IBM i)  applications to private, dedicated infrastructure within L3C Cloud or to the major public cloud providers such as Skytap on Azure (AIX on Azure), and IBM Cloud  / IBM PowerVS. We also provide connectivity into AWS for Unix applications deployed within our UK data centres. L3C’s SPARC cloud infrastructure allows legacy SPARC/Solaris environments to be brought into digital transformation initiatives and integrate with applications deployed in public clouds. 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.
