LAMP Development
Posted by: Lans in Case Studies on February 1st, 2009
LAMP refers to a stack of free software programs that are used to run dynamic sites or servers such as Linux, Apache, MySQL the database management system or PHP, the programming language.
LAMP offers unique advantages such as:
- Open source community along with knowledge sharing as well as resource sharing contributes in problem solving. Libraries of sample application code along with knowledge bases of the community help to reduce development time by allowing adaptation as well as re-usage.
- The compactness of LAMP component stack is easy to deploy and helps in reducing the processing overheads.
- The users have great level of flexibility at their disposal as LAMP can run on a wide range of platforms. The user also has the option to install on clusters or grids of economical x86-based servers. The computing architecture of the utility offers an optimized combination of efficient resource utilization, versatility, high availability and instant scalability.
- The LAMP server stack possess a lower bug density

ERP
Posted by: Lans in Case Studies on February 1st, 2009
Enterprise resource planning helps in integrating all departments and functions within a company in a single computer system that serves specific needs of different departments.
ERP is often referred as back-office software and does not run the up-front selling process. When the customer service representative enters the customer order in the ERP system, he has access to all the required information such as customer’s rating, company’s inventory levels from the warehouse module, and shipping dock’s trucking schedule from the logistics module.
Enterprise Resource Planning (ERP) originally implied systems designed to plan the use of enterprise-wide resources. Although the acronym ERP originated in the manufacturing environment, in today’s world ERP systems has much broader scope.
Enterprise Resource Planning systems (ERPs) integrate (or attempt to integrate) all data and processes of an organization into a unified system. A typical ERP system will use multiple components of computer software and hardware to achieve the integration. A key ingredient of most ERP systems is the use of a unified database to store data for various system modules.
Enterprise Resource Planning (ERP) delivers a database containing:
- Manufacturing
- Supply Chain Management
- Financials
- Projects
- Human Resource
- Customer Relationship Management
- Data Warehouse
SME Organizations with international and domestic Purchases through multiple channels would benefit the most from this type of technology.
COMMON FEATURES
- This technology is web based and can be accessed from anywhere in the world through secure VPN.
- Linux based Server no licensing fees.
- MySQL based, one of the strongest open source databases available, for which no license fees needs to be paid.
- Porting Option for any database
- Independent Platform for all major browsers.
- Takes very less resources.
- Supports multiple companies.
- User based authentication.
- Transaction Log user specific.
- Can merge CRM & SCM at a later point to integrate with suppliers and clients
- Source code with the client, so not a vendor dependent solution.
Advantages offered by Us
- Our ERP solutions offer high operational efficiency by facilitating greater integration and focusing attention on specific demands of businesses.
- Our ERP solutions help in improving business responsiveness with the help of fast and effective applications and agile IT architecture.
- Our industry tailored application helps in speeding up delivery times, greatly reducing project risks and setting & running up the process fast.
ERP Customization Services
We help in customizing an ERP package that can be very reliable and cost effective. ERP packages are designed to support customization, so most businesses implement the best practices embedded in the acquired ERP system. Some ERP packages are very generic in their reports and inquiries, such that customization is expected in every implementation. It is important to recognize that for these packages it often makes sense to buy third party plug-ins that interface well with your ERP software rather than reinventing the wheel.
Customization work is usually undertaken as bespoke software development on a time and materials basis. Because of the specialist nature of the customization and the ‘one off’ aspect of the work, it is common to pay in the order of per hour for this work.
Collaborative Environment
Posted by: Lans in Case Studies on February 1st, 2009
A collaborative development (CDE) is essentially a virtual space in which stakeholders of a particular project meet, brainstorm, share, discuss, negotiate or labor together. It has been seen that there is a certain pattern of behavior in hyper-productive teams. The popularity of the web as an extension of an important medium of interaction along with new dimension added to the work culture due to outsourcing as well as off shore development and integration of the third party software has been responsible for the development of web centric service oriented architectures.
Open source projects are characterized by their distributed developers, openness and a use of a community-based development process. Successful open source projects such as Apache, Linux and PHP have a web based collaborative development environment (CDE) that provides source code repository access, knowledge management, discussion lists, bug tracking and user support.
Any organization working on projects would require certain tools to manage entire development life cycle of project. Metatron Labs’ solutions include GForge, Collaborative Development Environment and Source Code Repository & Knowledge Management that can implemented as per the requirement of the company.
We provide implementation and support services on GForge, an Open Source Collaborative Development Environment (CDE). GForge has tools to help teams collaborate, create and control access to Source Code Management repositories like CVS and Subversion, Manage file releases, Document Management, News Announcements, Task Management and more.
Application Servers
Posted by: Lans in Case Studies on February 1st, 2009
An application server is a server program in a computer in a distributed network that provides the business logic for an application program. The application server is frequently viewed as part of a three-tier application, consisting of a graphical user interface (GUI) server, an application (business logic) server, and a database and transaction server. More descriptively, it can be viewed as dividing an application into:
- A first-tier, front-end, Web browser-based graphical user interface, usually at a personal computer or workstation
- A middle-tier business logic application or set of applications, possibly on a local area network or intranet server
- A third-tier, back-end, database and transaction server, sometimes on a mainframe or large server
The ease of application development is the major advantage offered by appservers. As the applications do not have to be programmed and are assembled from building blocks provided by the application server.
Open Source application servers give a great ROI and low TCO along with inbuilt stability and inherent advantages of Open Source. We provide Open Source application servers broadly under two categories -
J2EE application server stack
Following the success of the Java platform, the term application server sometimes refers to a Java Platform, Enterprise Edition (J2EE) application server. The better known commercial open source J2EE application server is JBoss (Red Hat).
Programming language used is Java, the Web modules are servlets and JavaServer Pages, and business logic is built into Enterprise JavaBeans (EJB). J2EE provides standards for containing Web components.
A Java Server Page (JSP) is a servlet from Java that executes in a Web container—the Java equivalent of CGI scripts. JSPs are a way to create HTML pages by embedding references to the server logic within the page. HTML coders and Java programmers can work side by side by referencing each other’s code from within their own.
LAMP application server stack
The LAMP (Linux, Apache, MySQL, PHP/Perl/Python) open source stack has been the technology of choice for a “scale out” architecture. LAMP provides a reliable way of deploying rich Web 2.0 applications on inexpensive clusters of commodity computers. Controlled by no single vendor and backed by broad open source global community, it now powers nearly 70% of the world’s web.
Until now organizations with significant expertise in handcrafting LAMP implementations could benefit from LAMP’s scalability and cost savings. However, things have changed now; We have worked on LAMP stack for more than a decade now and has gained features expected by corporate developers.
We offer various types of application server along with Apache Application Server, Perl Server, and Enterprise JaveBeans.
