Managed platform has reduced our operations workload and delivers faster cluster startups

I wouldn't say it's specifically an Oracle Linux pro, but when using Oracle Linux with a Kubernetes engine, it provides you with all the necessary libraries that it needs for a startup. This means quicker startup time and quicker joining to the cluster. It's just fast when you use Oracle Linux because it's optimized for your OKE engine. When I mention quicker startup time and easier joining to the cluster, it means you have a pretty good startup when you want to scale, you don't have to wait longer times just for your nodes to come up. When you have your traffic spiking, you don't want to wait that two to three minutes extra for a node to join the cluster, so that's where you have that advantage. And even for the customers when we give them access, it's a better startup since it's optimized and has all the necessary libraries. When I mention our workload is reduced because it's managed and optimized, it is approximately 80 to 90 percent of our workload is reduced because Kubernetes also releases frequent updates. You don't have to migrate to a new one; when you're migrating, it's pretty quick. All the security patches are handled by Oracle. The newer updates are provided by Oracle, and you don't have to test it. You will need to do some rounds of testing, but way less than managing your own Linux.

Robust relational queries have supported secure user data growth and improve transaction safety

The best features PostgreSQL on Ubuntu offers are complex joins, which allow us to perform advanced SQL queries, providing the atomicity of our tables, ACID properties for transaction safety, and scalability that we can expand to, as we currently have 10 lakh users, and it is easily scalable. Complex joins are the best feature that PostgreSQL on Ubuntu provides because I have been using NoSQL solutions such as MongoDB, but PostgreSQL has better efficiency for complex queries when used correctly. PostgreSQL on Ubuntu has positively impacted our organization because, from the initial phase with around 1,000 plus users during user accessibility testing, we defined the tables in such a manner that even with future scalability increases, it would function well, and now it has grown to 10 lakh users, still holding up well with fast data retrieval and good query performance, supported by effective indexing methods. In our user table with PostgreSQL on Ubuntu, we initially added indexing on the email property, but after a while, we found that the phone number field was also frequently used, and adding indexing to it improved our query retrieving speed and efficiency by almost 20 to 30 percent.

Quotes from Members

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

Pros

"The solution provides the best return on investment."

"The configuration with Oracle database and Oracle Center databases is easy."

"Oracle Linux is very compatible with other platforms."

"The most valuable features are performance, frequent update patches, and security."

"If we use Linux, Solaris, or some other operating systems, we have to build a lot of packages using RPMs (the packet manager). That's a difficult task. With Oracle Linux, we use a single command to update from the Oracle website."

"The most valuable feature is the binary compatibility i.e. that Oracle Linux is 100% compatible with Red Hat Linux."

"Overall Oracle Linux is very good."

"The user interface is comfortable and easy to use."

More Oracle Linux pros

"PostgreSQL on Ubuntu has positively impacted my organization by being very reliable; it has solid recovery and the risk of data loss is very low, making it very robust and ideal for production projects."

"The best feature of PostgreSQL on Ubuntu is its structure because it adds clarity and understanding when investigating a database, which enhances readability and understandability for someone new to the project."

"PostgreSQL on Ubuntu has positively impacted our organization because, from the initial phase with around 1,000 plus users during user accessibility testing, we defined the tables in such a manner that even with future scalability increases, it would function well, and now it has grown to 10 lakh users, still holding up well with fast data retrieval and good query performance, supported by effective indexing methods."

"We have worked with various databases including SQL Server and MySQL, but I found PostgreSQL on Ubuntu to be the most cost-effective and most performance-friendly solution."

"PostgreSQL on Ubuntu offers reliability, performance, and cost-effectiveness, which were the primary factors in our decision to choose this database."

"The best advantage of PostgreSQL on Ubuntu is its ability to fulfill all our requirements as an RDBMS; we frequently use various database-related operations such as storing, retrieving, and utilizing views and triggers, and its concurrency and connection handling are very efficient, especially since we have around 1,000 users."

Cons

"The documentation has room for improvement."

"What we found in moving from Oracle Linux 6 to Oracle Linux 7 was the whole interfacing with the application and the fact that operating had all changed, all the commands had changed. You need to be aware that there is some kind of training, some kind of handover required for your technical guys, understanding different ways of interacting with it. Bear that in mind."

"I would like Oracle Linux to have more frequent updates."

"The support process is time-consuming as it involves several steps."

"It could be more scalable."

"I think they should also pay more attention to the open-source community."

"Oracle Linux performs best on Linux or Unix. However, you cannot get the same performance or stability in Windows."

"Kernel updates need improvement."

More Oracle Linux cons

"From an improvement perspective, the UI of PostgreSQL on Ubuntu can be somewhat better because from my experience, it is outdated compared to current UI generations, and the reliability without changing the entire system architecture can also be improved, along with optimizing index management such as adding proper indexes and removing unused ones."

"I did notice one downside about PostgreSQL on Ubuntu. Certain queries were not behaving in the same way that SQL Server was handling those queries."

"PostgreSQL on Ubuntu can be improved because it is a bit slower than other solutions I have used."

"PostgreSQL on Ubuntu can be improved in terms of flexibility, which comes at a cost—specifically its learning curve and complexity."

Pricing and Cost Advice

"The product's pricing is cheap. The tool's pricing is yearly."

"The price of Oracle Linux could be less expensive for those who are running a small freelance company, such as I do. We use the solution fully but the income that you're receiving is slow."

"We have a yearly license, and I think Oracle charges too much."

"The licensing for this solution is based on the number of calls running Oracle databases, and are purchased either annually, or every three years."

"We pay an annual subscription."

"This is an open-source product that can be used free of charge."

"The solution has no fees."

"There is a license required for this solution and we are on an annual license."
