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.

Cons

"The documentation isn't very good and the options are very complex."
"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 graphical user interface has room for improvement and can be more user-friendly."
"The solution's scalability needs improvement."
"The customer service and support team can be improved."
"The solution should improve the cluster environment and load balancing."

"In the future, I would like to see better support for the REST interface."
"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 tool's implementation should be easier. The product is also expensive."
"The logs consultant, since it tends to be more in the server, we do need complete consult logs for a lot of different files."
"The error handling area in Oracle WebLogic Server is an area of concern where improvements are required."
"They should improve the solution's garbage collection feature."
"The pricing is a little bit higher compared to other products."
 

Pricing and Cost Advice

"The product's price is not high."

"The licensing cost is dependent on the usage."
"The price of Windows Server IIS is expensive. They have a large user base, and they charge a little bit too much."
"This solution comes included with Windows Server."
"There is no license required for the product as it is role-based. Whenever you go for a Windows platform server, the role has to be installed directly from the server manager. There is no additional cost that has to be paid for that. It is free to use."
"IIS's pricing is not expensive."
"We pay a yearly licensing fee for the solution."
"My company uses a licensed version of the product, so we get Oracle's support."
"It is expensive."
"Fees are paid on a yearly basis."
"In our country, this is an expensive product."
"The tool's pricing is yearly."
"I would not compare WebSphere and WebLogic because both servers are really good. The only difference is that Weblogic is lighter and consumes less memory."
"The licensing of the product is expensive"
"As Oracle WebLogic Server is a product from Oracle, it is bound to be an expensive solution. My company needs to make annual payments towards the licensing costs attached to the product."
