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.

Enables public access and secure configurations through reverse proxy

The primary valuable feature of NGINX for me is its ability to provide a reverse proxy. I have found that this feature supports our local server, and I am able to connect through our DNS system, making it accessible publicly. Additionally, the integration with SSL certificates and the configuration capabilities make it a valuable solution for my use case. Without NGINX, users would not be able to access our application, which means there is positive ROI from using NGINX as it is crucial for the functioning of my organization.

Quotes from Members

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

Pros

"The solution is very stable and robust."

"IBM WebSphere Application Server is one of the best servers due to its stability and paid license."

"I find IBM support to be very nice."

"The thing about WebSphere, as opposed to other ones that I am aware of such as JBoss and Liberty, is that WebSphere has the most comprehensive scaffolding available to it."

"Network Deployment is the most useful feature for scalability. It has many features within the standard WebSphere Application Server edition."

"The integration between IBM tools and applications is very well executed, and the support from IBM is quite good, providing a solid support structure."

"IBM WAS is extremely scalable. It is easy to add additional servers and to divide the load over servers in all kinds of ways."

"It has good stability of the application server in the long term compared to other solutions."

More IBM WebSphere Application Server pros

"NGINX Plus also has NGINX App Protect. It's a separate module, which is inspired by the F5 apps."

"When I worked in a security research center, we tested NGINX to support DoS and DDoS attacks, and its results were great."

"I need to highlight that the number one thing about NGINX is that it is free."

"Zero Downtime has always been a strength in recommending infrastructure web services. NGINX allows me to execute such infrastructure with less complications and the ability to switch from server to server easily."

"Application Gateway with application-level firewall tool and load distributor and balancer (also serves for A/B testing)."

"Nginx is extremely efficient in terms of the connection rate to the CPU cycles ratio, and in terms of the bandwidth to CPU cycles."

"NGINX Plus' most valuable feature is the ingress controller."

"NGINX works much better than HAProxy in our current hardware and architecture for HTTP/HTTPS load balancing. "

More NGINX Plus pros

Cons

"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."

"In the next release of this solution, I would like to see support for the Arabic language."

"The licensing could be improved, and I would like it to give the longevity of the lifespan of the visions. In the next release, I would like to be able to download and extract the files so that I can just use my application server."

"I think that this is a good product but I think that the cloud environment could be improved. I think that the future is in the utilization of the product in a product as a service way which is something that is lacking at this moment."

"The footprint could be reduced so that we can use a smaller virtual machine to run the application. We could also use more scripts. I would like this solution to be more script oriented, rather than GUI oriented."

"The installation has room for improvement."

"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."

"IBM needs to pay attention to market changes more quickly. We now have Java 9 and very soon Java EE8. We do not want to wait for two or three years after their release until they are supported by the new version."

More IBM WebSphere Application Server cons

"They should do in the open source version of what they did to Advanced HTTP, TCP, and UDP load balancing."

"It would be good if NGINX provided a graphical user interface."

"The biggest room for improvement would be to allow NGINX Core machines to cluster for memory zones in some way with a plug and play module. "

"One area of improvement could be that NGINX could provide a means to generate self-signed SSL certificates."

"Only improvement needed that I would point to is scalability. With it, I mean clusterized organisation on a low level. At the moment, the best alternative is RHEL HA."

"If NGINX brings some features for health check in the open source version, it would be better. "

"Lack of a feature to print data on the terminal for verification of network traffic during debugging and testing."

"I would like the configuration process to be more simplified."

More NGINX Plus cons

Pricing and Cost Advice

"My company is on a perpetual or permanent license agreement with IBM WebSphere Application Server. There's also a pay-per-use option, but customers rarely choose that option. Most of the customers are on the perpetual license deal that's all-inclusive. As the license cost is quite expensive, I'm rating it two out of five."

"The licensing cost is 1,000 of euros for a 30-year table."

"I don't remember the price, but there are no additional costs."

"Room for improvement would only be in the licensing. As with all IBM products the licensing can be complex and expensive. Bargain well and try to get as much discount as possible. Discounts of 85% are possible. Without the discount, I think the product is overrated."

"The licensing policy is based on the PVU base."

"The pricing is a little expensive."

"If your application is just a web app that does not need to scale big, you can obtain a single core license of WAS Express edition, which has almost the same features with limited processing cores. If you manage a very big application farm (i.e. need to run 10 or more WAS servers) it is better to get IBM WAS Hypervisor Edition."

"We pay around $200,000 annually."

More IBM WebSphere Application Server pricing and cost advice

"I use the solution's community edition which is free of cost."

"The cost is reasonable."

"HAProxy is cheaper than NGINX."

"The price is the cost to contract support with a specialized company, usually during consulting hours."

"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."

"The list price of NGINX Plus is close to $5,500."

"It's an open source solution, so it's free."

"You pay for each feature that you want."
