VikramSingh6 - PeerSpot reviewer
A simple and easy-to-use solution but not recommended for public apps
I would rate the overall solution a six out of ten. We have around five to six developers and engineers for the solution’s deployment and maintenance. You can use the solution if your website is not too big or complicated. However, if it is big and complicated, then you need to use Apache or Red Hat. This tool can be used for internal purposes. But if you plan to host a public app, then I wouldn’t recommend the tool.
Saikat Nag - PeerSpot reviewer
Offers efficient load distribution with a scope of high scalability
Our organization configures Oracle WebLogic Server in such a way that a load balancer becomes available. The network requests are segregated to the Oracle WebLogic Server as the managing server and different nodes are configured. Using the product as a load balancer helps automate request transfer from one non-functional node to another functional node. Due to Oracle WebLogic Server, the endpoints remain unaffected whenever a node goes down. The clustering feature enhances our organization's performance and reliability. In our organization, the health of the Oracle WebLogic Server environment is maintained and managed using Oracle Enterprise Manager (OEM). I would definitely recommend others to use Oracle WebLogic Server. Overall, I would rate the solution an eight out of ten.

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 the solution is that it is easy to use and easy to understand."
"The solution is highly reliable."
"Stability-wise, I rate the solution a nine out of ten...Scalability-wise, I rate the solution a nine out of ten."
"The solution works well in load balancing."

"It's a very stable solution."
"WebLogic is reliable, and it's easy to use for development."
"The product's installation phase is easy."
"What I find most valuable in Oracle WebLogic Server is its flexibility in administering and managing applications, along with the built-in dashboards that offer high visibility into vulnerabilities."
"One of the good features of Oracle WebLogic Server was the ability to add some custom parameters to its deployment and performance."
"It has good integration with security features, including OWASP."
 

Cons

"Scalability issues and security concerns need attention from Microsoft."
"The scalability depends on how you have set it up. If you're running IIS on a single server, it might not be as capable as if you are on many in a cluster or with load balancing and so on."
"The solution's black box is not fast."
"IIS needs to improve its security. Its support needs to be faster and clear. The tool's licensing could be cheaper as well."
"If Microsoft IIS could work well with AppOptics or things like PHP, Python, and other custom languages that run on the webserver, it would be ideal. I think there are cases where people need to use Apache instead of IIS when IIS doesn't work well with other web languages."
"Occasionally, we encounter performance issues with IIS where it becomes unresponsive and requires a solution restart."
"It lacks a few performance improvement tools."
"The documentation isn't very good and the options are very complex."
"The quarterly updates can sometimes lead to instability depending on the configuration of systems."
"In the future, I would like to see better support for the REST interface."
"Oracle WebLogic Server's configuration could be improved because we need to do multiple configurations when setting up anything."
"The pricing is a little bit higher compared to other products."
"Having clearer mechanisms to directly map a database-level connection problem to the corresponding WebLogic thread would greatly enhance the administrator's convenience."
"The cost could always be lower."
"The tool's implementation should be easier. The product is also expensive."
"There are always ways to improve. But it's getting better every time, with every new release, and every new patch, it's getting better."

"The licensing cost is dependent on the usage."
"The licensing of the product is expensive"
