Featured Review
Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
"Solaris's best features are high availability, robustness, and database hosting.""Solaris is scalable because they have their own file system, like CFS.""The stability of the solution is good.""The most valuable feature of Oracle Solaris is the incremental backup that happens in the system.""This product handles databases well; they run on top of the operating system.""This product is stable, has good documentation, lots of solutions, a big community, and good support.""It works well. It is very stable and very good. It is also very safe. It cannot be easily infected by viruses or attacks.""One of the main features of this solution is the ease of use."

"We find the Red Hat Satellite deployments very useful. It integrates well with other solutions.""I like the fact that most of the system configuration is Namespace so it's easy to get to and easy to configure, and most of it still uses text documents. Not all of it's a menu-driven-type entry. I also like the fact that it's a very standard file system layout so it's easy to navigate.""The Red Hat support is most valuable. My team and I are really good at Linux, and we can do almost everything in any kind of Linux solution, but sometimes, we have a really nasty problem, and the Red Hat engineering support at the third level has been fantastic. They know how to fix almost everything. The reason why I pay so much money to them is to have this kind of service and assurance.""We use this product's built-in tracing and monitoring tools such as syslog and SAR (system activity reporter) to provide us with greater insight and visibility into what's going on.""The security features are better than many other solutions offer.""The integrated solution approach reduces our TCO tremendously because we are able to focus on innovation instead of operations.""The biggest benefit is from a security standpoint. As the product progresses and they come up with new versions, the new security features are addressing vulnerabilities. From that perspective, it has worked well.""The AppStream feature provides access to up-to-date languages and tools in a way that interoperates with third-party source code. It makes it a lot easier to maintain that, as well as keeps our developers happy by having newer versions of development languages available."

More Red Hat Enterprise Linux (RHEL) Pros →

"This product is not as flexible as other similar solutions on the market today.""The Solaris code is open, and the documentation is accessible to all, not only to registered users. Also, the documentation does not support some solutions, and there are no other options.""Solaris is not easy to use. It needs better GUI, UI, and configuration tools.""It is not easy to use. It doesn't have a user-friendly interface. It should be easy to use. We are planning to move from Solaris to Linux because Linux is more flexible and user-friendly. Its installation should also be easier. Solaris also needs specific hardware to work well, which is another reason why we are moving to Linux. It should be more flexible in terms of hardware. It should have better integration with other hardware platforms.""Solaris' package management could be improved, especially in comparison to Linux.""Oracle Solaris can improve by supporting all the recent features that are in the market from other competitors.""It would be helpful if the solution offered backend management. In the 11.4 version, Oracle added a management console. It would be great if we maybe had a user management tool to go with it.""I believe before Oracle was using Oracle Linux, they were using Oracle Solaris for their customers who are using Oracle databases. This was because it was more optimized for the hardware built for it. It has good performance for the database only. However, if you take it out of the Oracle applications, it will not do well compared to other operating systems, such as Linux or even Windows can have better performance."

More Oracle Solaris Cons →

"In the past and with older versions, you couldn't expand the root file system without rebooting the server or restarting the operating system. That is something that they have actually corrected now, which is great. They corrected that issue somewhere around RHEL 7.""Their pricing and documentation can be improved.""I would mostly like to see improvement around corporate messaging. When Red Hat 8 came out, and Red Hat decided to change, it inverted the relationship between Red Hat and CentOS. This caused my customers who had a CentOS to RHEL development to production workflow quite a bit of heartburn that several of them are still working out. A lot of that probably could have been avoided through better messaging.""Red Hat's standard deployment is with Satellite and Kickstart, but we're looking at other options to help speed it along. We do have a mix of bare metal and virtualized servers and it's easier to spin up in the virtualized world versus bare metal. That's why we're looking at some options outside of Red Hat, for the bare metal.""I'd like to see more of NCurses type menu systems in some instances. We're dealing with SUSE Enterprise Linux, they have an NCurses menu system. It's a menu system. It will write there. Even some of the higher-end Unix systems like AIX have some inner menu system where all the configuration tools are right there so your administrator doesn't have to jump through multiple directories to configure files if needed. I like the simplicity of Red Hat because it's pretty easy but having an NCurses menu when you have to get something done quickly would be nice.""The biggest thing that is crushing RHEL is documentation. Their documentation is haphazard at best. The man pages that you can use locally are pretty good, they've been fleshed out pretty well, but the documentation from Red Hat itself really needs somebody to go through it and review it.""The vulnerability assessment part should also be improved. We do a lot of patching regularly. They try to fix an issue very quickly, and we also end up facing bugs that are not properly documented. When releasing the general availability for a particular solution, they need to do a lot more work on their side.""Could include additional security fefatures."

Pricing and Cost Advice
  • "There should be an option to install the solution for free and just pay for the support. We purchased an annual license and the price could be better."
  • "Its licensing is on a yearly basis."
  • "The price is not good and needs to improve."
  • "This solution needs a license to use it."
  • "There are no licensing fees but you can opt to pay for support."
  • "It is a very expensive product."
  • "The price of Oracle Solaris could be less expensive."
  • More Oracle Solaris Pricing and Cost Advice →

  • "Red Hat Linux is inexpensive. Linux solutions are generally inexpensive."
  • "RHEL is expensive."
  • "Because it is a subscription, you can go elastic. This means you can buy a year, then you can skip a year. It is not like when you buy something. You don't buy it. You are paying for the support on something, and if you don't pay for the support on something, there is no shame because there are no upfront costs. It changes the equation. However, we have such growth right now on the Linux platform that we are reusing and scavenging these licenses. From a business standpoint, not having to buy, but just having to pay for maintenance, changes a lot of the calculations."
  • "We have a site license on a yearly basis. Generally, we're okay with its price, but everything could be cheaper."
  • "The licensing with Red Hat is on par with other organizations like Microsoft. We have a site license, which gives us a certain number of servers, perhaps 25,000, for the type of license that we have. That works really well for us."
  • "We are an educational institution and as such, what we pay is less than the average company."
  • "It is more expensive than other vendors in terms of pricing and licensing, but because of its stability, I have to go with it."
  • "If you don't buy the Red Hat subscription, you don't get technical support, and you don't have all the updates. To have everything working like a charm, the cost that you pay for it is worth it. In Bolivia, we don't have the best internet connection. Therefore, we have a local service with all the packages, repositories, etc. We manage them locally, and because we have a subscription, we can update them. So, we have local repositories with all the packages and other things to make it easy for us to update all the servers. Without the Red Hat subscription, we cannot update anything."

    Reviews from Real Users

    Below are some reviews and helpful feedback written by PeerSpot users currently using the Oracle Solaris solution.

    A CEO at a computer software company says, “The most valuable feature is virtualization. They have attained virtualization and it's quite simple to create the Oracle Solaris zones. The solution is quite powerful. Oracle Solaris is great due to the fact that it actually is meant for high-end servers. The high availability is great. You can clone and you can do quite a number of things with them. There's also the ZFS File system which is very good. Is one of the best file systems that there is.”

    Diego A., Oracle ACE - Specialized in Systems Technologies at Telecom Argentina, mentions, “The most valuable features for me are virtualization (Containers, Zones, Security, PDOM's, LDOM's) and Performance, ZFS, Debugging with Dtrace.”

    A Service Manager at a tech services company expresses that the solution is “Stable, scalable, and has easy installation.”

    PeerSpot user Marcel H., Oracle ACE Director "Solaris," CEO, Enterprise Consultant at JomaSoft, explains, “Solaris includes two virtualization solutions: LDoms for SPARC and Solaris Zones. Both solutions can be combined to create private clouds. Solaris Zones is ideal to separate applications and to migrate from older to current hardware. LDoms is very efficient because it uses the hardware hypervisor of the SPARC servers. Both technologies increase Security, because they separate the applications from each other. Using the Security Compliance Framework we are sure the systems are set up properly.”

    Shafiq K., Senior Manager IT Operations at a financial services firm, states, “The reliability of the solution is excellent. The security has been very good overall. We've found the solution to have good availability. The backup capabilities are quite good. The solution has proven to be quite stable so far. The product can scale. The solution is 100% free to use. It doesn't cost a company anything as it's embedded in the hardware.”
