Has worked seamlessly in complex clustered environments and supports long-term development efforts

IBM WebSphere Application Server is currently at version 9.0.5.23. In recent months, they released fix 23, as they periodically release fixes. Previously, they frequently increased versions, but now they maintain 9.0.5 with different releases. It's based on Java J2EE 7 and Java SDK 1.8. Oracle announced that 2030 will be the last year when Java SDK 1.8 will be supported. Oracle currently deploys Java 2.x in parallel, with the latest being version 25. The future of IBM WebSphere Application Server remains uncertain since it's based on Java 1.8 and Java 7. I haven't found any white papers or official documentation from IBM outlining their trajectory post-2030.

Improved security and streamlined cloud deployments have reduced maintenance and simplified troubleshooting

The Visual Studio ID that we are using requires more RAM and IP. Sometimes it goes high on this phone exchange, and it crashes sometimes. We have to review this with Microsoft itself. That is something we do not understand. The breakage goes up, and I think it was the process that decreased, but still partitions are there somehow in Cloudera Selami. We do not even understand what the issue is. I think six more RAM would help.

Quotes from Members

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

Pros

"The most valuable feature of this solution is Portal Virtualization."

"We needed this type of integration and WebShepere is the best tool for it."

"The only reason why we're currently using WebSphere is that the integration of the authentication with Azure is very quick. WebSphere has something that can immediately connect with Azure Active Directory."

"The scalability of the product is quite good."

"High availability, alert management, and deployments are the most valuable features for us. We have the ND version so we can do deployments."

"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."

"I would say that the clustering, achieved by using the deployment manager, is valuable, as there is a load balancing feature that uses different nodes, handled by the deployment manager, and this functionality helps with the load balancing of applications."

More IBM WebSphere Application Server pros

"When using Microsoft .NET Framework, you start writing the code internally."

"Microsoft .NET Framework has introduced many new features, making the technology very vast."

"Firstly, I appreciate the decision to use Microsoft .NET Framework. I find it to be an excellent language, with a history rooted in providing an alternative to Java, albeit with initial challenges. It is gaining popularity and may be voted the most desirable programming language. What I particularly like about .NET is its language efficiency. While C# is the primary language, the platform also supports others, catering to those inclined towards functional programming. Although I started with Shell, I'm still grasping the concept of functional programming. Despite initial reservations about object-oriented programming, I acknowledge its advantages. .NET is a safer option, and despite criticisms, it has evolved over the years. One notable aspect is .NET's transition to an open platform in recent years, distancing itself from being exclusive to Microsoft engineers. I appreciate the versatility of .NET, enabling code production for a wide range of platforms, presenting a strong competition to Java. It allows targeting practically any physical platform, showcasing its flexibility. These qualities contribute to my positive view of .NET, totaling thirteen aspects that I find appealing."

"The addition of generics to handle common functionality across types, and the more recent upgrade of the dataset to the Entity Framework, has cut development time drastically, while increasing quality and confidence between builds."

"The most valuable feature is customization."

"It is a stable solution."

"With Microsoft .NET, the dynamic web content handling became easier and the Microsoft world of web became more programmable with use of reusable and redistributable web components and systems (building blocks)."

"Our solution should work for roughly 50,000 users every day."

More Microsoft .NET Framework pros

Cons

"The future of IBM WebSphere Application Server remains uncertain since it's based on Java 1.8 and Java 7."

"Since we've been monitoring it directly ourselves, we've found that there has been an increase in the number of failures. The failures result in deadlock processes that generate very little to no troubleshooting logs."

"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."

"The solution could improve the integration."

"The availability of the solution needs improvement. The product should be more enhanced and responsive."

"WebSphere is very cumbersome and not user-friendly."

"The installation has room for improvement."

"The security could be better."

More IBM WebSphere Application Server cons

"Microsoft could improve .NET Framework by providing more resources to help users understand the solution."

"The product is nearing its sunset, and we think that by 2028, we won't get support anymore"

"The price of the Enterprise version is quite high and can be improved."

"The .NET open source community is very small and it would be nice if it were larger."

"Lacking in auto-scaling."

"The product's price is an area of concern, making it an area where improvements are required."

"The integration capability of the product with AI is an area with certain shortcomings, where improvements are required."

"The learning curve could be improved."

More Microsoft .NET Framework cons

Pricing and Cost Advice

"IBM WAS base is part of the deal when you purchase IBM FileNet P8 Content Engine."

"There is an Eclipse Plugin provided by IBM, so no need to buy IBM Rational Application Developer or Rational Software Architect tools."

"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."

"When you purchase Maximo, you get WebSphere for free."

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

"The price of this product is higher than that of competitors."

"It costs more than some of the others, but, you get what you pay for."

"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."

More IBM WebSphere Application Server pricing and cost advice

"The Microsoft .NET Framework is free of charge, without licensing cost."

"Do your homework. Consider the partnership program."

"Microsoft .NET Framework is licensed under the Windows License."

"Microsoft .NET Framework is a free, open-source solution."

"I rate the solution's pricing a two out of ten because .NET is an open-source framework. You don't have to pay for a license."

"There is a Community Edition that can be used free of charge, but the licensing cost for the Enterprise version is quite high."

"The product and support for this solution are free for everyone."

"We have an annual license, and we pay extra for extended support."
