Training
Our flagship offering of Linux Kernel Internals comes in variations to suit the needs of individuals and corporates. Both these courses is suited for people who have been programming in UNIX environment, and are now ready to take next step into the art of programming in Linux Kernel. This course is intended to provide good overview of linux kernel at each subsystem level. The Linux kernel Internals Onsite is suited for companies which require a sufficiently large batch of people trained and would like to have the session on company premise. Alternatively individuals or companies with a requirement to train a few individuals should opt for the Linux kernel Internals Offsite. This will be held at regular intervals at KQ Infotech premises.
We offer training/seminars and consulting in the following areas.
- Storage Technology (File system/Volume Manager)
- Cluster File System
- Linux, AIX and Solaris Kernels
- Advanced Unix programming
- Virtual technologies like (Xen and VMware)
