Efficient load balancing and the clustering, achieved by using the deployment manager, is valuable
I believe that the system is already good. However, for improvement or enhancement, it is user-friendly, but it could offer better choices on the front end for different aspects or options. Sometimes, I have to search extensively for features, as there are no upfront tabs. There is a lack of visible, easy, user-friendly, and straightforward options for the number of features.
Pavan Kodur - PeerSpot reviewer
Intuitive, easier to develop, maintain, and migrate from the old framework to newer versions
There are a few areas where they could compete better with products like React or Angular – the popular SPA (Single Page Application) frameworks. Microsoft has its own product called Blazor, but I don't think it's quite as powerful yet as React or Angular. I think that's an area for improvement. For example, HR asked me to build something that worked offline and online. Microsoft products don't really support that well, as I'd have to rely on browser databases. React and Angular are better for that. If I need something faster, I'd definitely use React. So, I see Microsoft lagging a bit in that area.

Quick installation and very easy to manage while doing orchestration or automation
NGINX cannot be a replacement for your traditional load balancer with what we use in the network today. However, with applications going toward microservices, NGINX is definitely a way forward. F5 has many traditional load balancing features, so they still need to bring some of those features to NGINX. NGINX is a very basic load balancer and cannot do as many customizations as F5. I think F5 is trying to implement those features in NGINX so they can improve the balancing on NGINX, but I think that will take some time. With the traditional F5 set up, the same OS can do load balancing, firewalls, and even policy enforcement. If we are able to bring some of those capabilities to NGINX, I think it would become a versatile solution and usage would definitely increase.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"WebSphere Application Server's best features include the data subscription and connection viewer."
"It has good stability of the application server in the long term compared to other solutions."
"One of the most valuable features might be the stability of the IBM WebSphere Application Server."
"The VPN service is quite useful."
"The scalability of the product is quite good."
"Without the Admin Console it would be very hard to configure JVM settings, JDBC datasources, mail session settings, and security providers."
"The performance is good."
"Ease of administration: It has an Integrated Solutions Console, what we call the administrative console, with very detailed configurations and Help pages for each configurable item."
"The most valuable features for us are web frameworks like MVC, Web API, and WCS."
"Microsoft .NET Framework’s most valuable features are web application development, RESTful services development, security, performance, and less memory footprint."
"A great solution for creating program solutions in a framework for Microsoft Windows quickly and easily."
"In-built refactoring and .Net profilers are the most valuable features of the solution."
"It's easy to create and integrate things."
"I'd rate the solution as highly stable."
"The solution's technical support is very good...The product's initial setup phase was easy."
"Given that it's cross-platform right now, where you can use it on Windows and Mac, that is the single most significant feature that has resulted in wider adoption of .NET."
"I need to highlight that the number one thing about NGINX is that it is free."
"NGINX provides a cost advantage, value addition, and effective support."
"When I worked in a security research center, we tested NGINX to support DoS and DDoS attacks, and its results were great."
"The product is resilient."
"Using NGINX Plus for web traffic distribution is fantastic. It offers performance similar to physical load balancers but with added flexibility."
"NGINX Plus also has NGINX App Protect. It's a separate module, which is inspired by the F5 apps."
"The overall product rating is ten out of ten."
"-"
 

Cons

"IBM WebSphere Application Server hasn't changed much. It's still a heavyweight for any company compared to what you get. Unless your code base is deeply linked with it, I don't think it's a great idea to go with this solution. The current trend is toward modularity and containerization, and given the product's requirements, containerization will be difficult. There is a memory requirement as well."
"Based on the field and based on the build that was provided, we've noticed a lot of constraints in terms of the performance now."
"WebSphere is very cumbersome and not user-friendly."
"In the next release of this solution, I would like to see support for the Arabic language."
"Sometimes, I feel WebSphere runs a bit slow. It might be loading unnecessary libraries, impacting its performance compared to other application servers."
"When we run into memory or locking issues, we resort to using third-party tools. However, it would be preferable to have native tools for debugging this type of problem."
"What could be improved in IBM WebSphere Application Server is its interconnection with other products, for example, Kafka. What I'd like to see in the next release of the solution is a better graphical user interface."
"While WebSphere mostly supports IBM HTTP Server (IHS) as the web server plugin, I think it would be beneficial if it also supported Apache and NGINX web servers. That would give customers more flexibility in their choices."
"The .NET open source community could be larger."
"Better integration with other tools to make the operation faster would be an improvement."
"Needs stronger security with respect to cloud issues."
"There are performance constraints when multiple users are accessing the application and that consumes CPU resources."
"Improvements are needed in .NET development, particularly in a backend scenario."
"I would like to see a better response time from the technical support."
"Difficult to scale this product for large organizations."
"I would like more web integration."
"The scalability could be improved."
"Our most challenging part was to run an older PHP website reverse-proxied through NGINX. That was not fun."
"Initially, I experienced hiccups whenever I installed the application."
"The scaling should be built into the software rather than configured from an outside source."
"I would like the configuration process to be more simplified."
"The center management system could be improved."
"I would suggest adding GUI-based configuration panels to NGINX Plus to simplify setup and management tasks."
"The solution's GUI is an area with certain shortcomings that need improvement."
 

Pricing and Cost Advice

"We used to pay about $100,000-$120,000 US or somewhere around there. That was a bit cost-prohibitive for us to continue."
"The price of this product is higher than that of competitors."
"It is very expensive."
"IBM WAS base is part of the deal when you purchase IBM FileNet P8 Content Engine."
"It's expensive."
"When you purchase Maximo, you get WebSphere for free."
"There is an Eclipse Plugin provided by IBM, so no need to buy IBM Rational Application Developer or Rational Software Architect tools."
"The licensing cost is 1,000 of euros for a 30-year table."
"The pricing could be cheaper."
"The product is not expensive."
"The Microsoft .NET Framework is free of charge, without licensing cost."
"Microsoft .NET Framework is very cost-effective for corporate users."
"The solution is free but you need to pay for a license for the hosting service."
"If you want to develop an enterprise-level application, you have to purchase the enterprise-level development license."
"Microsoft .NET Framework is free of cost."
"The support is an extra cost when purchasing the license. The price of the solution is overall reasonable and paid annually or every three years. Additionally, they have a monthly license. The cost is approximately $1,000 per user."
"The cost is reasonable."
"Nginx is free. I don't have experience with the Plus version."
"​NGINX Plus is worth it, if you need it. If you do not need the features or support, the free and open source package is more than capable. ​"
"I am not so happy with their pricing policy, but this is not the worse thing in my life. I can tolerate it."
"It's an open source solution, so it's free."
"NGINX Plus is an open-source solution with limited additional features. When you try to get additional features in the solution, then you need to pay an extra amount to NGINX Plus."
"​NGINX is a free tool in Brazil. There are some companies which do support it.​"
"HAProxy is cheaper than NGINX."
