There is no specific "chaturvarnya" system in Kerala.
The Ancient
Chera kings of Tamilakam (
From which Kerala culture originates) were mostly nature worshipers and were later influenced by Buddhist and Jain practices.

Large scale Brahmanical migration between
6th and 8th century AD, is what brought the structured caste sysytem to Kerala, but it still didn't follow the 4 Varnas strictly.
The closest thing to Kshatriyas we have in kerala are from the
Nair caste , which includes subgroups such as
Menon, Pillai, Nair , Nambiar etc . Who were accorded
Shudra status by the Brahmins (or Aryan Jains ?), but allowed to
perform Kshatriya functions.

Thus , in the absence of the traditional "Kshatriya posts", the groups within the Nair caste took up many of the "Kshatriya functions". Them being a traditional Marital race (
nairs and
Thiyya/Ezhava were the main marital races present in Kerala,
both communities have unproven theories of them being descendant from some nomadic tribes from the north of India and above, the same tribes who allegedly are the forerunners of the Jatts and similar north india marital communities. But the theories are unproven).
This led to the emergence of the Nair based kingdoms which ruled kerala till Independance.

So [MENTION=130700]TM Riddle[/MENTION] if you come across a mallu with a surname
"Varma/Verma", he/she is very likely to belong to the later era ruling class of Kerala.
But the ruling class were more or less under Brahmin control till the period of independence.
The name
Varma is derived from Dravidian word
varamban (which was used to denote "
ruler". So it may also have been adopted by all the communities that performed administrative functions.
Northern surnames such as
Verma, Varma , Burman, Devvarman etc are all variations of this root word. But they need not be related to the malayali "varma" kings.
