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
Metatron Labs, being aprofessional Internet consulting and application design company caters to both Indian & overseas clients. We specialize in, LAMP (Linux, Apache, MySQL, PHP and Perl), software design application development with database integration and overall LAMP consulting. We maintain a team of software consultants, creative designers, programmers and marketing professionals that know software and good development practices so you don’t have to invest into another part of business process.
Would you like to move away from packaged delivery of software, into a world of hosted application where you receive monthly subscriptions from your customers for your software?
LAMP may be the architecture that you need to get there. We can make this happen for you, from planning the hosting environment to development of LINUX, Apache, MySQL, and PHP.
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.
Remote Server Management
Posted by: Lans in Case Studies on February 1st, 2009
Vigilance is necessary for maintaining the health of the IT environment in any organization. But generally, organizations lack the expertise or necessary resources to do so.
