The internet's early days saw a web primarily serving as an information archive stored locally within organizations. Over time, internet software, also known as distributed applications, have become vital for online services. These applications are built using platforms like Java or .NET, powering popular apps such as WhatsApp, Facebook, and Gmail today.
Distributed Application Platforms These are software frameworks designed for creating distributed systems. Java, developed by James Gosling at Sun Microsystems in 1995, remains a widely-used language for such applications. Microsoft’s .NET framework, introduced in 2000, supports Windows-compatible distributed app development. Visual Studio offers an integrated environment to streamline this process.
The concept of distributed applications originated with early distributed computing, including programs like Creeper and Reaper within the ARPANET network in the 1970s. In 1988, the first internet-based software was developed at DEC. Projects like distributed.net in 1997 and SETI@home in 1999 showcased the potential of using the internet for data sharing and distributed processing, popularizing this innovative approach.
Applications These systems power messaging apps such as WhatsApp, enabling instant text, voice, and video communication. Social media platforms like Facebook and Twitter rely on distributed architecture to reach millions efficiently. Ecommerce systems and desktop applications also benefit heavily from these technologies.
Architectural Types To understand distributed application development, it's essential to grasp these main architectures:
Client-Server Architecture This straightforward design can expand from simple two-tier setups to complex multi-tier systems.
Broker Architecture Utilizing the Common Object Request Broker Architecture (CORBA), this setup manages communication between distributed components.
Service-Oriented Architecture (SOA) Combining client-server and broker models, SOA facilitates flexible, modular system design.
Advantages of Distributed Internet Software These systems offer numerous benefits:
Resource Sharing Multiple hardware, software, and data resources are shared seamlessly, enhancing efficiency and reducing overhead.
Flexibility Despite sharing resources, applications operate independently, allowing for adaptable and reusable solutions.
Fault Tolerance Designed to withstand partial failures, these systems ensure continuous operation even when some components encounter issues.
Scalability Modern systems easily scale up or down to meet evolving technological demands and user needs.
Continuous Updates Distributed systems are regularly upgraded, maintaining security and performance without disruption.
Internet-based distributed applications have significantly simplified daily tasks and enhanced connectivity worldwide, thanks to the innovators behind this technology.
