Linux distributions offer us a number of benefits whether we use them as private users or at a corporate level and one of them is the ability to increase all its features in a comprehensive way thanks to free code..
We currently have different distributions of Linux and today in TechnoWikis we will concentrate on a special one that has been developed thinking about the corporate environment which requires solid, secure, broad systems that can be scaled based on the increasingly growing market needs .
Today we will analyze how to install SUSE Linux SP3 dynamically and thus make the most of each of its benefits..
What is SUSE?
SUSE Linux Enterprise Server 12 SP3 is a server operating system that differs from its competition because it is a reliable, scalable and secure system for all efficient implementation tasks of business class IT services, which may be available in physical environments , virtual or in the cloud.
SUSE Linux, has been designed for mixed IT environments, offering the best performance with a lower risk of technological obsolescence or vendor blocking which is an added bonus for corporate environments where information availability is always required.
SUSE Linux features
SUSE Linux Enterprise Server 12 SP3 offers a series of benefits where we highlight:
- Robustness in administrative errors and improved administration capabilities with the complete system reversion based on the btrfs file system and it has SUSE snapper technology, including the service package reversion, that means that when we implement SUSE Linux we are making use of a reliable system and totally capable of managing and correcting possible failures in the course of its useful life.
- Wide scalability, since it has been shown that SUSE Linux is capable of supporting up to 8192 CPU cores and 64 TB of RAM, these are major words where it will be possible to manage thousands of servers without losing speed or performance, and additional support for the XFS file system for more than 10 consecutive years.
- SUSE Linux has the only integrated stack of local systems administration in Linux: for interactive use (YaST), scripting (AutoYaST) and integration into multi-machine system administration environments such as SUSE Manager.
- SUSE Linux has the Advanced Systems Management and KIWI technology, which is an open source system that allows you to create images of operating systems whose objective are physical implementations and provisioning in virtual hypervisor environments, container frameworks (Linux Containers, Docker) and public and private clouds.
- The modern management of the open source network gives us the possibility of using the network configuration as a service and also has software-defined network capabilities thus facilitating the administration of these.
- Compatibility with open source hypervisors such as Xen and KVM, and virtualized open source controllers for all major hypervisors that currently exist.
- Support for Linux Containers integrated in the virtualization management infrastructure which gives us the opportunity for better management of virtual environments.
- Interactive and unattended update from the latest version of SUSE Linux Enterprise 11 to SUSE Linux Enterprise 12 SP1 in all 32-bit and 64-bit architectures.
- Integration with the new SUSE Customer Service Center, the central SUSE web portal to manage subscriptions, rights and provide access to the Support since it is necessary to have a subscription for the use of the operating system.
