[http://www.imcredel.com/open-source/zen-lb-open-source-load-balancer Zen Load Balancer] is an [http://www.imcredel.com/open-source/zen-lb-open-source-load-balancer Open Source Load Balancer] Appliance Project that provides a full set of tools to run and manage a complete load balancer solution which includes: farm and server definition, networking, clustering, monitoring, secure certificates management, logs, config backups, etc.

2. BASIC CONCEPTS
Farm is a set of servers that offer the same service over a single one entry point defined with an IP address and a port, which is commonly called virtual service. The main farm work is to deliver the client virtual service connection to the real backend service and back. Meanwhile, the farm definition establishes the delivery policies to every real server.

Backend is a server that offers the real service over a farm definition and it process all the real data requested by the client.

Client is called to the IP address that connects to the virtual service of the initial connection that usually a user requests. The client IP address that opens a new connection on the virtual service side is used to communicate with the user. The same client could generate several (layer 4) connections to the virtual service, and an IP client address could be generated by several users.

Application Session is a layer 7 concept which tries to identify the requests of a single user although several clients shares the same IP client address.

Real IP is a physical IP address over a layer 4 network configuration which is assigned to a server or NIC.

Virtual IP is a floating IP address over a layer 4 network configuration which is used to be the entry point of a virtual service defined by a farm that is ready to deliver connections between redundant load balancing nodes.

3. ZEN INSTALLATION

3.1 DOWNLOAD THE INSTALL ISO IMAGE
The load balance appliance installer is able to be downloaded from the official website that could be used to:

Burn an installer CD-ROM to install under a physical machine
Record on an USB device to install on a physical machine with usb boot support
Install on a virtual machine through a virtualization software

One of the most common applications of load balancing is to provide a single Internet service from multiple servers, sometimes known as a server farm. Commonly, load-balanced systems include popular web sites, large Internet Relay Chat networks, high-bandwidth File Transfer Protocol sites, Network News Transfer Protocol (NNTP) servers and Domain Name System (DNS) servers. Lately, some load balancers evolved to support databases; these are called database load balancers.

For Internet services, the load balancer is usually a software program that is listening on the port where external clients connect to access services. The load balancer forwards requests to one of the "backend" servers, which usually replies to the load balancer. This allows the load balancer to reply to the client without the client ever knowing about the internal separation of functions. It also prevents clients from contacting backend servers directly, which may have security benefits by hiding the structure of the internal network and preventing attacks on the kernel's network stack or unrelated services running on other ports.

Some load balancers provide a mechanism for doing something special in the event that all backend servers are unavailable. This might include forwarding to a backup load balancer, or displaying a message regarding the outage. Load balancing gives the IT team a chance to achieve a significantly higher fault tolerance. It can automatically provide the amount of capacity needed to respond to any increase or decrease of application traffic

[http://www.imcredel.com/open-source/open-source-it-management Open Source It management ] system take care of all the It management task in a efficient and cost effective manne.Enterprise software such as Enterprise Resource Planning (ERP) and [http://www.imcredel.com/open-source/ebase Customer Relationship Managemen] t (CRM) are unique. Because every business that uses them is different, ERP and CRM software must be custom tailored to the needs of each business. Traditionally, that has meant either custom developing an ERP or CRM system for the specific requirements of an organization or purchasing an existing ERP and CRM system and customizing it.

Both approaches have significant issues. Custom development projects often start innocuously. "We know what we need, so let's do it." "Doing it" in software development, though, could be expensive and risky, and the majority of custom software development projects ultimately fail to meet the needs of the users.

But the greater risk is actually "knowing what you need." Even if the custom developed software met the needs at the time it's developed, it may not follow best practices in the industry or properly anticipate the long-term needs of the organization. As technology and business needs change, the organization is saddled with the burden of modifying the software. This is why industry studies have shown that long-term maintenance costs are often three to four times the original cost of software development.

Purchasing a commercial ERP or CRM system from a vendor presents a different set of issues. On the surface, this option may seem appealing because it eliminates the risk of custom development, obtains both industry best practices and the latest technology, spreads out development costs across the vendors' customer base, and makes the vendor responsible for long-term maintenance of the software.

In reality, commercial ERP and CRM software could be expensive and difficult to customize, and leave the user vulnerable to "vendor lock-in." Commercial software requires significant upfront licensing fees, often before an organization truly understands whether the software will fit its needs. It is also written based on the vendor's vision of an "ideal" company. If that deviates significantly from the user's reality, there is limited ability to change it because you don't have access to the source code. Finally, if the vendor is bought, goes out of business, or simply discontinues a product, the user may be left without any means to support his applications.

The Open Source Alternative

[http://www.imcredel.com Open source] brings an alternative which addresses many of the key problems of both custom and commercial enterprise software. It begins by offering the user a freely available code base as a starting point. The user can try it for free to see if it meets his needs. There is no risk of upfront licensing fees for software that may not work.

If no modifications are required, open source software can be implemented with the same rapid time-to-market as commercial packages. If customizations are required, the user has a head start with an existing code base. Furthermore, he can leverage the expertise of both in-house and open source community developers. An open source project brings with it the domain knowledge and business requirements of many contributing organizations, significantly reducing the specification risk typical of custom software. Open source communities also offer user-developers collaborative help in developing and debugging of his software. The net result is better software in less time.

Longer term, open source offers the user the control of custom software and the external resources previously available only with commercial software. With the source code in hand, the user can decide on future support and upgrades. There is no one to "discontinue" the software for him. At the same time, because the software shares the common roots with open source, he can obtain support and upgrades from the open source community or purchase professional-quality support from a range of vendors in the community. Thus, the risks of becoming "stranded" due to the loss of vendor support or key employees are significantly reduced with open source.

Mammootty the Malayalam movie megastar was born to Ismail (an agriculturist) and Fatima (a homemaker). He had two younger brothers Ibrahim and Zakariah; and three sisters, Ameena, Sauda and Shafina. He did his high school (pre-degree) at Maharaja’s College, Thevara and then studied law at Ernakulam Government Law College. It was during his days at Maharajah’s that he got his first role a bit part in Anubhavangal Paalichakal in 1971. He practised as a criminal lawyer in Manjiri for 2 years. He got married in 1980 to Sulfaath. He was ‘discovered’ by M.T. Vasudevan Nair who cast him in the unfinished ‘Devalokam’. K.G. George was another mentor of Mammootty’s who made him into a bankable superstar. He has a daughter, Surmi (b. 1982) and a son, Dulquar Salman (b.1986). He made a brief foray into Hindi films but did not create much of an impact. He has won numerous Indian National awards.

In a period of five years from 1982 to 1986 Mammootty acted in more than 150 films in the lead role.[18] In 1986 alone, he acted in about 35 films in the lead role.[17]

The mid 80s saw a period of tear-busting stories in Malayalam film. Most of the films were tragedies. This period featured what later came to be referred to as the 'Mammootty-Kutty-Petty' films. These films had Mammootty as the protagonist, a husband and a father, with a 3–4 year old daughter, and employed in a top ranking post in a company. Mammootty made a comeback with New Delhi and Thaniyavarthanam, both released in 1987. New Delhi was a very important movie in his life as an actor. The film was loosely based on the novel, "The Almighty" by Irving Wallace. His portrayal of a victimized journalist, who systematically took revenge on politicians who flattered him, was noticed and well accepted by the masses. Meanwhile, his role as Balan mash in Thaniyavarthanam, written by Lohithadas and directed by Sibi Malayil, was critically acclaimed.

In 1988 Mammootty delivered one of the biggest hits in the history of Malayalam Cinema with his Oru CBI Diary Kurippu. Oru CBI Diary Kurippu went on to create box-office history in Kerala as well as in Tamil Nadu. Mammootty's role as a CBI officer in this film got him critical acclaim. Following the success of the first CBI film Oru CBI Diary Kurippu, three more murder mystery sequels were produced with the same cast of characters: Jagratha (1989), Sethurama Iyer CBI (2004) and Nerariyan CBI (2005), all directed by K. Madhu, penned by S. N. Swamy with Mammootty as Sethurama Iyer, an intelligent but unassuming CBI officer. The films by M. T. Vasudevan Nair and Padmarajan, arguably among the best of Malayalam writer-directors, widened Mammootty's acting horizon. Two of M.T. Vasudevan Nair's films with autobiographical elements were acted by Mammootty. One was Aksharangal directed by I. V. Sasi and the other was Sukrutham directed by Harikumar.

Mammootty touched the pinnacle of his career in Oru Vadakkan Veeragatha; the film was directed by T. Hariharan and penned by M.T.Vasudevan Nair. His depiction of a Chekavar (mercenary warrior) of distinguished valor but vilified by circumstances won him the National Film Award for Best Actor. Along with the huge commercial success of the film, Mammooty was given rave reviews about his lead role in the film, which required heavy physical and psychological preparations. His role as a hunter Varunni in Mrigaya, directed by I.V. Sasi, and another film Mahayanam, was also scanned for the State Award. Mammootty won the Filmfare award for Amaram directed by Bharathan. He played the role of an uneducated fisherman who dreams of making his only daughter a doctor.

During this time, Mammootty appeared in many of the films directed by Adoor Gopalakrishnan's. He starred in three of his films, Anantaram ('Thenceforth'), Mathilukal ('Walls') and Vidheyan ('The Servile'). His portrayal of the protagonist in Mathilukal (based on 'Mathilukal', a novel by the ace Malayalam novelist Vaikom Muhammad Basheer) was instrumental in getting him his first National Film Award for Best Actor. Mammootty also portrayed the roles in Adoor Gopalakrishnan's Vidheyan and T V Chandran's Ponthan Mada. He received the National Film Award for Best Actor and State Award for his roles in both films. His performance in Valtsalyam directed by Cochin Haneefa was also considered for the State Award. The King, scripted by Renji Panikkar, was released in 1995 and was directed by Shaji Kailas. Mammootty played the central character as a District collector and it turned out to be the biggest hit of the year.

In 1997, he won the Filmfare Award for Best Actor for the movie Bhoothakannadi directed by Lohithadas.

In 1999, [http://www.mammootty.info/ Mammootty] won his third national award for Dr. Baba Saheb Ambedkar, an English language movie about the life of Ambedkar, directed by Jabbar Patel.[23] The film was sponsored by the National Film Development Corporation of India and the Ministry of Social Justice. The film was released after a long and controversial gestation period.
