IT Enterprise Open Source software on Linux delivers high performance solutions for all IT needs. These solutions generally combine reliability and security with low-cost of acquisition. Open Source gives organizations flexibility in selecting and implementing the IT infrastructure that best suit their strategic goal. - Linux storage solutions file servers, file sharing, clustered storage - High availability - Business continuity/recovery - Security - Enterprise infrastructure - Enterprise management Storage: - Smaller organizations and even home users enjoy the benefits of SAMBA file servers.They integrate well with Windows workstations offering centralized secure storage as the foundation for any evolving IT infrastructure.Providing access control,they can also share internet on wireless or wired network.RAID and LVM Linux features will increase storage reliability and flexibility.This solution take advantage of inexpensive large capacity SATA storage and will scale well. - Enterprise Storage:Datacenter applications require clustered filesystem to counteract risks of data corruption when numerous users intensively and simultaneously read and write data.Improvement on the Linux 2.6 kernel permits clustered filesystems to maintain data consistency during simultanous read and write operations for large data pool across several storage servers. High Availability/Business Continuity Numerous solutions will maintain your network and servers operational,preserving you from the pitfalls of systems downtime. - back-up and recovery solutions protect your data.RAID-native software on Linux offers resilient inexpensive data redundancy. - Scheduling backups to DVD is now widely practiced.Open Source software will also allow you prompt 'bare-metal' server recovery under most adverse circumstances. - Load balancing and failover provide stability to your server operation.While Load balancing optimize volume of transaction between servers, fail-over constantly monitor specific servers for signs of failure in order to send traffic to an alternate server. - Network Services Monitoring solutions can monitor level of traffic on the network,volume of request activity and performance in transaction processing.Such data are critical in assessing the operational performance of network. - virtual machine are now deployed under Xen open source 'hypervisor'.This technology offers high performance server consolidation.Different server installs can occur in one physical machine.'live-migration' feature offers increased availability. Network Security Business impact assessment help focus security planning on critical services in your infrastructure. - numerous open source firewall solutions are available to help protect your network - secure routing and bridging - port scanners, root-kit detection, network vulneranility and penetration tools - IDS (Intrusion Detection Systems) IPS (intrusion pevention systems) - Wireless network can be secured using FreeRADIUS (802.1X) EAP-TLS authentication server AAA (authentication, availability, accounting) - various encryption techniques can be adapted to your operation to protect sensitive data being stored or communicated. - password cracking, consistent password policy to prevent unauthorized access. - VPN technology offers secure remote acess to telecommuters - SSH (secure shell) encrypted secure remote access to servers Enterprise Infrastructure - Enterprise Directory Services using LDAP: directory services can now offer centralized sign-on/access to other enterprise network applications and services such as web, e-mail access. It is practical in implementing overall access control and tracking user activity. Users Various GUI can ease its configuration and management. Other services include: - Webmin - mail service: Sendmail, Postfix, Qmail, Qpopper - SpamAssassin, Amavisd,ClamAV - Name services BIND, DHCP, web, file transfer, database MySQL, etc... - IPmasquerading, NAT, DNAT Enterprise Management CRM/CMS/LAMP Applications LAMP (Linux Apache MySQL PHP) platform is very robust, inexpensive server based technology can work with any browser so is highly suitable for any intranet or extranet environment. - MySQL expands the scope and power of applications that can be offered through web interface. Fast processing of complex queries, easy integration with Apache web server, and the flexibilty that PHP offers for query/results formatting. Can be customized to any requirement. MySQL 5.x delivers outstanding high performance, high availability (replication), scalability, and live backups. - Powerful open source CRM and CMS also deploy on LAMP. Organizations now have solid performance and stability record upon which to build the foundation of their business process. Integrating a CRM platform with existing infrastructure and services is carried out through LDAP. Customer relationship Manager provide: - compnay portal - web email client generally supporting IMAP or POP servers - calendar - address book - task manager - forum/discussion - project strategizing and management - collaborative information management platform (wiki) - bookmarks - company news/announcements system - knowledge management/repository - integrated workflow/productivity management
