Introduction Among the most successful e-commerce sites, eBay is one of the leading web companies in the world. eBay allows business-to-consumer and consumer-to-consumer sales through its e-commerce site.

Get the original essay Since eBay's inception in September 1995, this web-based company has enabled transactions worth billions of dollars and currently serves people in many countries, including Australia. , France, Ireland, United Kingdom, Canada, etc. (Marshak 2003 p. 2) Information systems and technology play a vital role in business success. There are no warehouses, inventory or physical store on eBay. This business uses technology and information systems that allow people to sell and buy things online. They generate their income from the commissions they receive when the products are sold (Chen 2005 p. 77). Information Technology Infrastructure To realize its full potential, e-commerce must develop a strong and appropriate supporting infrastructure (Galant Jakubczyc and Paprzycki 2002). ). IT infrastructure is the central element used in all e-commerce platforms. It is used to connect parts of the organization with its customers, suppliers and associates. Investment in information technology infrastructure is as important as investment in physical infrastructure in machinery, equipment, plant and land (Weill and Vitale 2001 p. 1). IT infrastructure includes hardware, software, communications resources, management, data centers, physical facilities, and electronically stored data (Weill and Vitale 2001 p. 2). Pierre Omidyar, founder of the eBay application created by eBay. Initially, it was just a local auction app. Its original application which was a two-tier application and was built on C++ language. The system was limited and did not have the potential to handle the increased traffic nor could it support the various business processes other than eBay auctions (Chen 2005, p. 78). Over time, eBay grew and by 2005, eBay included 200 database servers and 20 search servers. eBay has a grid-like architecture that makes eBay more efficient. Besides the search function, around 50 servers can be used to manage everything on eBay. Servers include application servers, web servers, and data stores (Julia Layton 2005). How eBay manages its IT infrastructure In this paper, we will analyze how different components, including web servers, web clients, databases and application servers, interact with each other and how eBay manages them. Web Browserscustomer uses the company's website through a web browser such as Microsoft Internet Explorer or Google Chrome. The user interface is supported by web browsers and customers can make a selection of anything using the eBay website. Once the client submits the request, this system software transfers the data over the network. Proxy Servers The proxy server will receive requests from web browsers. The cache of these servers constantly accesses web pages. So whenever a user wants to retrieve something, they can retrieve it without actually accessing the website. On the contrary, if the customer wants to sell or bid on a certain item, the real-time data must be shown to him. These types of servers are often located close to clients and on the same network, saving a large amount of resources (Ahmad p. 4). Load Balancing and Web Servers Load balancing component is one of the important elements of eBay website as it promotes and maintains availability, performance and scalability. The main purpose of the load balancer is to distribute the load (incoming requests) among a set of computers operating web servers. Therefore, performance is improved. Additionally, the load balancer also takes care of the computers and if one of them goes down, it diverts incoming requests to the other set of computers, thus taking care of availability. From the load balancer, requests are forwarded to the web server. These servers have the ability to do multithreading. After processing from here, the web server sends it to an application server which responds using database services. The application server and database application server receive requests from web servers. Application servers operate amidst eBay's business rules. Business logic and connectivity are implemented through these servers, which guarantee how clients and servers will interact. The EJ2EE application server framework is used by eBay as a replacement for C++ ISAPI which was previously operated. The queries finally reach the databases and here they are transformed into instructions to modify, add or extract the information. Below is the image showing the different components of eBay's IT infrastructure and how they interact with each other (Ahmed p. 3). Challenges Faced by eBay and Suggestions to Overcome As eBay's business grew, the company faced several issues related to its infrastructure and was forced to expand. in different ways. Growing Demands As eBay grew, the website was no longer enough to handle the traffic. This can be by visits, minutes spent on the site, registered members, articles placed on the platform or even the number of transactions carried out. eBay continually restructures its scalability (Marshak 2003 p. 3). Second, the growth of the services that eBay offers and intends to offer in times to come. eBay has introduced many new services such as eBay Stores and Buy It Now. From the initial auction model, eBay has expanded its services in new directions (Marshak 2003 p. 3). Vendor Management PayPal, as a seller of eBay, has introduced different retail POS solutions here, like Paypal. If PayPal continues to grow in point-of-sale transactions, this may lead to fraudulent activity, which ultimately harms eBay by increasing fraud and associated risks such as transaction losses. The PayPal business is growing continuously, but it is not.
