PostgreSQL (alternately Postgres) is a free and open source object-relational database system boasting over 30 years of active development, reliability, feature robustness, and performance. It supports SQL and is designed to support various workloads flexibly.
SQL Server is an excellent product from Microsoft, it is a derivative from Sybase which originally developed the SQL Server form Unix and Linux, and Microsoft purchased it to migrate the DBMS to Windows Server. But the cycle comes full circle, and now Microsoft recommends its …
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.
If you have one user or 1000's of users (especially using Windows), Windows Server is a no-brainer! The only reason I would suggest going with a Linux server is if you have old hardware (Windows Server is more process intensive than Linux). But, Linux is open-source, so anyone can publish updates/security updates, but on the flip side, malicious people also have full access to Linux's codebase allowing for much easier writing of exploitations/viruses/malware/ransomware.
DHCP Server could be better - we use the router for DHCP Routing
Print Server - not a fan of using the server as a print server since you have to license it. Direct access to printers via IP addresses is a much more efficient way to go
Better backup program - we utilize a third-party program that gives us more flexibility when restoring individual files.
I've carefully reviewed the servers and services currently running on Windows Server 2012, and given the opportunity would renew them as is going forward. There are two systems I currently have in place, one is a very large Linux implementation for a large ecommerce site, and one is a very large backup solution front ended by FTP servers running Linux. Neither are well suited for Windows, but the overall network infrastructure is and will be Windows Server for the foreseeable future.
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.
There are simply too many different parts of Windows Server to make it a cohesive piece of software. While some of the newer features found in Windows Server 2012 and 2016 have nice UIs that are logically laid out, there are enough parts of the system that is still based on old code with clunky UIs and confusing options to make Windows Server a particularly user-friendly experience.
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.
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.
Microsoft's support is hugely wide-ranging from articles online to having to contact them directly for the more serious issues. In recent years when I have contacted them directly, I have found the support o be excellent as I have found myself connected to very knowledgeable people in the field in which I needed the support. The online support available is vast and I tend to find most of the time that there is always someone out there who has had the same issue as me in the past and knows something about how to resolve it! This is the advantage of using industry standard and long-established systems such as Windows Server.
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.
Make sure that you have detailed processes in place for every server instance you plan to install/upgrade, if possible get the base OS loaded and Windows Updates applied ahead of time, and if using a VM take a snapshot prior to installing each role, as well as along the way.
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.
I didn't use any other system which gives the same functionality and I am not aware of any. The full integration between all components and especially the ability to integrate mail via Exchange or even via a hybrid setup with the Ofice365 cloud, including the ability to directly manage the cloud from the server, using Power Shell, is something I didn't see anywhere else.
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.
Because of our Microsoft Campus Agreement, Windows products are fairly affordable for us and that has been a huge blessing. We are considering some Azure cloud options and some of that is covered under our Campus Agreement, making it a nice incentive to start migrating certain apps and functionality to the cloud
I don't have access to our budgets so I cannot give a good answer as far as the impact of ROI on our institution, but if your company can afford it, you cannot go wrong with Windows server. Not having to send your sys admins to Linux or Unix school alone is a big savings as well as not having to train your staff on using a Linux desktop instead of a Windows-based one.
The compatibility with end users of all varieties and platforms will definitely impact your ROI in a positive way. We have Apple users, Android, Windows, and even a few Linux end users on our campus and Windows server works quite well with all of them.
