There had to be a solution to fill the gap and PostgreSQL came in as a viable alternative and has become the choice of enterprises for moving their databases to open source. MariaDB is an open source fork of MySQL that was intended to continue the open source legacy of MySQL, but it didn’t really take off in the enterprise world. Ever since its acquisition by Oracle bin 2010, its roadmap became uncertain and enterprises started moving away from it. Until a decade ago, MySQL used to be the default choice of enterprises for migration to Open Source databases. PostgreSQL is an enterprise class, feature-rich open source database system that is highly reliable and extremely performant and very suited for real-time and mission critical applications.
You can also run PostgreSQL on Cloud at a much cheaper cost by manually hosting PostgreSQL instances in Linux instances running on the Cloud. Note that AWS also provides PostgreSQL as an RDS service at roughly half the cost but without built-in high availability. This model has high availability and support built-in with a pay-as-you-go pricing model and is best suited for small and medium businesses. One such offering is AWS Aurora (PostgreSQL compatible). One such company, EnterpriseDB, provides support for Open Source PostgreSQL as well as its own fork of PostgreSQL.Ĭloud solution providers also provide PostgreSQL as PaaS offerings. Note that the software itself is still free to use, the price is for support only. But the good news is that there are third-party companies that provide support to Open source databases. On the other hand, open source software is provided “as is” if you host it on your servers and you’re on your own when there is any issue. They have your back (at least on paper) when your databases are down due to software bugs & vulnerabilities, heavy loads or other hardware and network issues. Licensed software like SQL Server and Oracle are backed by their respective vendors and provide support as part of their license or separately, depending on the licensing model. Moving from Licensed Software to Open Source Migrating from commercial to open source databases results in significant cost savings for enterprises in terms of licensing and support. Open Source Databases provide the same or even better functionality at a significantly lower cost. Enterprises have been shying away from Open Source software primarily due to the fact that there is no support in case of any major issues. While there is no question about the capabilities and strengths of licensed and proprietary databases, their highly restrictive pricing model and a significantly higher Total Cost of Ownership (TCO) for large installation bases has made enterprises and medium businesses look towards less expensive open-source solutions.
