    Chose IBM Power Virtual Server
    From the starting of the 18th century, IBM is leading the IT industry. Not actually the industry but the IT in R&D, IBM is the one to build computers. That’s the reason, IBM is very old in this market and its T&D is pretty well that’s the reason I chose IBM

    It is really impactful in terms of scenarios like ERP systems and Data Analytics where heavy data needs to be analysed in terms of volume and their needs to be high scalability offering so in that scenario it is a great asset and features like distribution of workload using AI capabilities by leveraging modern IBM offerings like Watson is really helpful the area in which it could improve is native development of application in terms of adoption of New cloud Technologies

    PostgreSQL is best used for structured data, and best when following relational database design principles. I would not use PostgreSQL for large unstructured data such as video, images, sound files, xml documents, web-pages, especially if these files have their own highly variable, internal structure.

    Pros
    IBM
    • It is good in managing our documents in a precise manner.
    • It is a comprehensive tool and supports other languages like JAVA and Python and it is useful for us.
    • It is quite a valuable tool available at a reasonable price in the market and it is a scalable tool.

    • It works well with external data sources and runs on platforms with stable performance.
    • Clients can rest assured that their personal information will be safe and secure.
    • Many forums discuss setup and usage, and most are free.
    • Adding tooling applications to a computer is unlimited.
    • PostgreSQL runs on many OS platforms and supports ANSI SQL, stored procedures, and triggers.

    Cons
    IBM
    • The software appears to be geared for a no-programming approach, which implies that making changes is more difficult.
    • The user base is small making it monotonous and difficult to come up with new methods.
    • The number of rankings is not as large as competitors.
    • The admin end is poorly designed, as they are unable to receive and respond to client feedback.

    • Clearer indications on what is the query plan, to optimize the query
    • More out of the box, Postgres specific, SQL functions
    • It would be nice to have a more visual aid of the relationship between all tables, but possibly this depend more on the UI used

    Easy to understand the architecture, easy of implementation and support with perfect documentation. Results driven performance in terms of latency and speed. Able to perform heavy workloads and huge transformations, also integrated SAP systems and Oracle robust deployments. But looking more in terms of AI capabilities to achieve more innovation.

    Usability
    IBM
    It provides strong support for Terraform, Ansible, and API-based management gives power users flexibility and efficiency and IBM Cloud UI is modern and relatively easy to navigate. Interfaces and workflows are consistent with on-prem Power Systems management tools. Areas to be improved - Compared to AWS or Azure, the UI could be more streamlined in how it presents all related services (e.g., networking, logging, storage) that tie into PowerVS

    Postgresql is the best tool out there for relational data so I have to give it a high rating when it comes to analytics, data availability and consistency, so on and so forth. SQL is also a relatively consistent language so when it comes to building new tables and loading data in from the OLTP database, there are enough tools where we can perform ETL on a scalable basis.

    The data queries are relatively quick for a small to medium sized table. With complex joins, and a wide and deep table however, the performance of the query has room for improvement.

    Support Rating
    IBM
    As with most IBM products the ongoing support for IBM Power Virtual Server is solid and consistent. IBM provides a clear roadmap for receiving support of their products. Both voice and online response is offered. It is obvious that IBM has the internal systems and culture to maintain support functions. This starts from the initial support call to the problem analysis and continues through the problem resolution. Documentation and communication are consistent within this process.

    There are several companies that you can contract for technical support, like EnterpriseDB or Percona, both first level in expertise and commitment to the software.
    But we do not have contracts with them, we have done all the way from googling to forums, and never have a problem that we cannot resolve or pass around. And for dozens of projects and more than 15 years now.

    The online training is request based. Had there been recorded videos available online for potential users to benefit from, I could have rated it higher. The online documentation however is very helpful. The online documentation PDF is downloadable and allows users to pace their own learning. With examples and code snippets, the documentation is great starting point.

    Alternatives Considered
    IBM
    They both have their own ups and downs and it totally depends on the team which suits them best. IBM Power Virtual Server has Performance, Scalability, Reliability and Availability, Compatibility, and Good Vendor Support. The specific use case and workload requirements played a significant role. Some workloads may benefit from IBM Power Systems' architecture, while others may perform equally well on alternative platforms.

    Although the competition between the different databases is increasingly aggressive in the sense that they provide many improvements, new functionalities, compatibility with complementary components or environments, in some cases it requires that it be followed within the same family of applications that performs the company that develops it and that is not all bad, but being able to adapt or configure different programs, applications or other environments developed by third parties apart is what gives PostgreSQL a certain advantage and this diversification in the components that can be joined with it, is the reason why it is a great option to choose.

    Scalability
    IBM
    Built to handle thousands of concurrent users, high query loads, and massive datasets especially in data-heavy industries like finance, healthcare, and manufacturing. In-memory processing, dynamic query optimization, and intelligent caching mechanisms help it scale efficiently under load. You can configure clusters of Cognos servers to distribute workload and ensure high availability, even during peak usage

    Return on Investment
    IBM
    • We have had a return on investment of 30%.
    • There have also been 80% fewer application crashes due to a lack of resources that previously ran on the X86 platform.
    • Administration management has been simplified and staff can dedicate themselves to the development of applications, instead of providing support to users when the applications do not respond efficiently, this made staff 45% more productive.

    • Easy to administer so our DevOps team has only ever used minimal time to setup, tune, and maintain.
    • Easy to interface with so our Engineering team has only ever used minimal time to query or modify the database. Getting the data is straightforward, what we do with it is the bigger concern.
    • It's free. You can't beat that.
