What is Web Server Accelerator Software?
Web server accelerators, also known as reverse proxies or application delivery controllers, are used to reduce the time it takes server side for users to access websites or web applications. These tools help speed up content transfer between web servers and client browsers through various technical means. Web server accelerators are a subset of web accelerators installed in front of application servers and web servers, using a variety of techniques to improve performance for users trying to access the website or application that the server is serving.
While web client accelerator software focuses on client-side improvements to connection speed, web server accelerators focus on improving connectivity at the web or application server front. Web server accelerator software has become a staple for many companies as they continue to grow and expand their data center and computing powers across the globe, especially as teams evaluate web server accelerator effectiveness metrics software ROI to understand performance gains, cost savings, and the business impact of faster application delivery. Based on G2 reviews, IT teams and infrastructure leaders evaluate web server accelerator software by comparing performance improvements, ease of deployment, reliability, scalability, security features, analytics, support quality, and overall ROI.
What are the Common Features of Web Server Accelerator Software?
Web server accelerator software is a great way to ensure that all servers are running smoothly and that there are no issues that could cause a possible downtime. The following are some core features within server acceleration that can help users ensure that their servers are running well:
Caching and prefetching: Fetching information from servers every time it is requested can be a timely process. To speed this up, web server accelerators can refresh cached content at specific intervals so that content is never out of date. It can also preempt the user, prefetching or caching the content the user might ask for. This ensures that the user will get the content without delay.
Compression: Large files can take a long time to process. Web server accelerators can compress these large files, such as video files, to reduce the time they take to transfer.
Secure socket layer (SSL) or transport layer security (TLS) processing: Although not present in all accelerators, some of the more advanced offerings can offload computationally intensive processing from backend servers, allowing them to serve content faster. For example, this is done with the decryption and encryption of documents during transmissions secured with SSL or TLS.
Server availability: Web server accelerator software allows the user to identify severely over or underutilized servers. This will enable administrators to set up a contingency plan in case there is a possibility of server failure. For instance, web server accelerator software can track the servers with low free disk space, is in a critical or warning state, has too high or too low device temperature, fan working is in a critical condition, etc. Then it would offload a few workloads to additional servers being underutilized.
Web Server Accelerator Effectiveness Metrics and Software ROI
Web server accelerator effectiveness can be measured by looking at simple metrics like how fast pages load, how quickly servers respond, how often the website stays online, how much content is loaded from cache, and how well the site works during busy traffic times. These numbers help IT teams see if the software is making web applications faster, reducing pressure on servers, and giving users a smoother experience. The ROI of web server accelerator software comes from fewer slowdowns, less downtime, lower bandwidth use, better server performance, and faster problem-solving before issues affect users or the business.

Web client accelerator software: Web client accelerator software is used to reduce the time it takes client side for users to access websites or web applications. While web server accelerator software focuses on server-side improvements to connection speed, web client accelerators focus on improving connectivity and load time within the client’s browser or application.
Challenges with Web Server Accelerator Software
Web server accelerator software solutions can come with their own set of challenges:
Managing an increasing number of servers: Paramount importance is being given to IT infrastructure, driven by the need to work from home and ensure business continuity. Companies are investing heavily in expanding their server infrastructure to support high-speed data processing, file transfers, and smooth operations. As the number of servers increases, it becomes difficult for web server accelerator tools to scale and keep up with the rate of servers being added, and therefore also need to be updated continuously.
Hardware health and environment issues: Some issues can happen beyond the control of the administrators, such as power outages, UPS failure, temperature and humidity levels in a data center, failure of the cooling system, and fan breakdown, which are hard to control. If a web server fails and the website freezes, server monitoring tools could be set up automatically to do a force restart and then check whether the issue is solved. If not, it can alert the required system administrators to check on what is causing the errors.
Seeing the big picture limitations: System administrators would use the software to answer the question, “Is my server working correctly, and if not, what can I do to fix it?.” Although this is the core capability of the software, there is a challenge of not looking at the bigger picture where the data and insight pulled from the monitoring software can factor well into strategic business decisions.
Web Server Accelerator Caching Solutions: Vendor Comparison
Web server accelerator caching solutions should be compared based on how well they improve real application performance and user experience. A strong vendor should help pages load faster by storing frequently requested content, reducing repeated requests to backend servers, and keeping applications stable when traffic increases. Businesses should also consider whether the solution supports prefetching, compression, SSL/TLS offloading, performance monitoring, and scalability, since these capabilities can help reduce latency, improve uptime, lower server strain, and support smoother content delivery as web traffic grows.
How to Buy Web Server Accelerator Software
Requirements Gathering (RFI/RFP) for Web Server Accelerator Software
When making a purchase decision to opt for a server accelerator solution, the primary goal is to select software that is well aligned with the buyer’s business desire and budget. For instance, if a buyer has a smaller budget and only requires software to maintain server health, they can opt for a free version or a basic offering with minimum features. Conversely, suppose a buyer requires software that can handle a gamut of operations and run large advanced tasks. In that case, they can opt for a more sophisticated and feature-rich web server accelerator software.
As companies continue to grow and expand operations, buyers must choose software that can support current server requirements and future upgrades. It is a good practice to check with the software vendor if the monitoring software can also support the buyer in the long term. This is extremely important to ensure hardware compatibility in the future as well.
Compare Web Server Accelerator Software Products
Create a long list
The buyer needs to scrutinize their company's IT systems environment and applications to choose the right web server accelerator software. This would include whether these servers are on-premises or virtual (on the cloud), the location of the servers, etc. Once the customer has decided that they require server accelerator tools, the next step would be to make a long list of the best web server accelerator software presently available in the market. Long lists help eliminate software that does not provide critical functionality, thereby reducing the list to be more compact and precise.
Create a short list
Once the list has been narrowed down, the customer can begin to compare different features and offerings of the web server accelerator software per the company's needs. Pricing decisions are also taken to ensure that the selected software fits the IT budget. A highly efficient method of comparing various web server accelerator software would be to opt for technology review platforms, such as g2.com, which provide unbiased reviews and different perspectives on the benefits or issues with various products.
Conduct demos
Once the list has been further narrowed down, customers can then opt to check if the vendors are providing a live demo or a free trial version (with limited functionality). This is a great way for buyers to ensure that the software is the right choice for the customer. They can use the trial versions before finally committing to the purchase decision.
Selection of Web Server Accelerator Software
Choose a selection team
Creating a selection team that will work together throughout the entire process, from identifying pain points to implementation, is crucial. The team should consist of organization members with the right interest, skills, and time to participate in this process. A good way is to get three to five people who fill roles such as the main decision maker, project manager, process owner, system owner, or IT administrator. In smaller companies, fewer participants would multitask and take on more responsibilities.
Negotiation
Prices on a company's pricing page are not always fixed (although some companies will not budge). It is crucial to open up a conversation regarding pricing and licensing. For example, the vendor may be willing to give a discount for multi-year contracts or for recommending the product to others.
Final decision
Before going all in, it is recommended to roll out a test run or pilot program to test adoption with a small sample size of users. If the tool is well used and well liked, the buyer can be confident that the selection was correct. If not, it might be time to go back to the drawing board.
