BharathirajaSukumar - PeerSpot reviewer
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.
Michael Olayemi - PeerSpot reviewer
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

"Network Deployment is the most useful feature for scalability. It has many features within the standard WebSphere Application Server edition."
"This solution is easy to use with a GUI that is intuitive and very helpful."
"We needed this type of integration and WebShepere is the best tool for it."
"The product offers good performance."
"WebSphere Application Server's best features include the data subscription and connection viewer."
"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."
"Security: It is compatible with the latest Java 8 security features, supports FIPS 140-2 and NIST SP 800-53 with strong ciphers and cryptography keys, and supports TLS 1.2 completely. Also, configuring client and server certificates is relatively easy."
"What's most valuable in IBM WebSphere Application Server is its resilience. When you use the solution, you know that after the communication has been done, there will be no doubt that the data has reached its destination."
"It's lightweight software that can handle heavy loads efficiently."
"The load balancing module, which is equivalent to LTM, is the focus of the PSE. So far, the features of both are identical. I believe NGINX has more features for securing these services, but in terms of load balancing, both are massive solutions."
"NGINX Plus also has NGINX App Protect. It's a separate module, which is inspired by the F5 apps."
"Its versatility and capabilities make it invaluable for implementing patches and fixes when necessary."
"It performs very well. That's one of the primary reasons we use NGINX."
"When you use NGINX, you have more options and power."
"Using NGINX Plus for web traffic distribution is fantastic. It offers performance similar to physical load balancers but with added flexibility."
"-"
 

Cons

"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."
"WebSphere is very cumbersome and not user-friendly."
"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."
"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."
"The solution consumes hardware."
"I think in some moments, the security was a little bit more complex to configure when it was delegated to other systems, making it an area where improvements are required."
"It should be able to serve more concurrent requests like Oracle. Oracle has more powerful stability, availability, and real-time serving."
"The solution could improve the integration."
"Make modules easier to enable or disable. The beauty and ugly side of the NGINX modules is you have to know how to compile the module. For beginners or non-very technical aspirant(s) going for NGINX, they have to learn how to compile the modules.​"
"They should do in the open source version of what they did to Advanced HTTP, TCP, and UDP load balancing."
"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. ​"
"It would be good if NGINX provided a graphical user interface."
"I would like the configuration process to be more simplified."
"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."
"One area of improvement could be that NGINX could provide a means to generate self-signed SSL certificates."
"If NGINX brings some features for health check in the open source version, it would be better. ​"
 

Pricing and Cost Advice

"WebSphere Application Server is expensive, so it may not be a good option for small companies."
"We used to pay about $100,000-$120,000 US or somewhere around there. That was a bit cost-prohibitive for us to continue."
"When you purchase Maximo, you get WebSphere for free."
"The price of this product is higher than that of competitors."
"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."
"It is very expensive."
"The pricing is a little expensive."
"The licensing policy is based on the PVU base."
"You pay for each feature that you want."
"​NGINX is a free tool in Brazil. There are some companies which do support it.​"
"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."
"HAProxy is cheaper than NGINX."
"There's an open-source version of NGINX that is free."
"I am not so happy with their pricing policy, but this is not the worse thing in my life. I can tolerate it."
"​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. ​"
"Nginx is free. I don't have experience with the Plus version."
