Precedence: bulk

Christophe is spot on when it comes to the PostgreSQL software.

Not trying to be "snarky" or condescending, but there are some other consid=
erations.   "Open Source" or "Free" does not mean "without cost".

No matter where you decide to host the software, there will be storage, com=
pute, and network costs, not only to support the software itself, but also =
the data you store.

With respect to the data, since you or your employer have decided to persis=
tently store the data in a database, I would presume the data, and more imp=
ortantly, access to that data, has value.

It seems from the original post that you've decided to pay someone (a cloud=
 vendor) to "take care" of the storage, network, and compute "services".  T=
hat's great!

But, what about that "non-licensed" software?   Once you use that software =
to store and access your data, you have created a CONTINUING need for that =
software.   What will it cost you or your employer if a "bug" in that softw=
are prevents access to, or worse yet, corrupts your data.

Are you willing to sign up for "maintaining" PostgreSQL in your environment=
, INCLUDING things like patching, finding and fixing bugs, upgrades, backup=
 and recovery, and off-hours support?  If you or your employer have any con=
cerns about this, and IHMO, you should, you might want to consider a "licen=
sed and supported" version of PostgreSQL.  There are several out there, inc=
luding EDB and others.  Even the big cloud vendors have "support plans" for=
 PostgreSQL.

Oh, and don't forget, a backup only as good as the last time you tested a r=
estore.

 Just need guidance if I can install the available version from site for bu=
siness purpose too or I must buy licenses? Will appreciate an appropriate r=
elated answer.

PostgreSQL itself is an open source project distributed under a very permis=
sive license:

        https://www.postgresql.org/about/licence/

No payment is required to download and run it.
