With the rise of AI and large information, phrases like “information lake” and “information heart” are sometimes utilized in overlapping discussions – however they refer to completely totally different ideas. An information heart may host a knowledge lake, however past that, the 2 have little in frequent.
So why the confusion? Each play a job in managing and storing huge quantities of data, and as organizations scale their AI and analytics capabilities, the infrastructure and information administration methods behind them turn out to be more and more intertwined.
Right here’s a better take a look at what a knowledge lake is, the way it differs from a knowledge heart, and why the excellence issues.
What’s a Knowledge Lake?
A information lake is a software program platform that servers as a central repository for information. Usually, the aim of knowledge lakes is to host the assorted varieties of information {that a} enterprise must handle. Knowledge lakes can function a web site for internet hosting structured information (like databases) in addition to unstructured information (like movies or emails).
Knowledge lakes grew to become fashionable beginning a few decade in the past. On the time, most companies that wanted to handle or course of information on a big scale relied on so-called information warehouses, that are much less versatile as a result of they’ll normally solely help structured information. By providing a centralized place to retailer virtually any sort of knowledge, information lakes facilitated various information administration and analytics use instances.
Knowledge lakes have advanced through the years, with some information lake platforms including options designed to boost information governance and safety or streamline information processing. Nonetheless, the core function of knowledge lakes – centrally storing information of various varieties – stays unchanged.
How is a Knowledge Lake Completely different from a Knowledge Heart?
The distinction between information lakes and information facilities is that information lakes are software-based repositories for info, whereas information facilities are bodily services that home IT tools. They’re essentially distinct entities that handle fairly totally different wants.
To be extra particular, the important thing variations between information lakes and information facilities embody:
-
Knowledge lakes are software program platforms, whereas information facilities are bodily areas.
-
The one factor you may retailer in a knowledge lake is information. An information heart can host information within the sense that information facilities usually home the bodily infrastructure essential to retailer info, however the principle function of knowledge facilities is to deal with servers.
-
Knowledge facilities embody bodily programs like HVAC and energy infrastructure to maintain IT tools working. Knowledge lakes don’t embody any of those elements as a result of they’re software program platforms, not bodily services.
Frequent Floor: The place Knowledge Lakes Meet Knowledge Facilities
If individuals are typically confused about how information lakes differ from information facilities, it’s most likely as a result of information facilities can host the underlying bodily infrastructure used to construct information lakes.
To create a knowledge lake, you want no less than one server (usually, you’d use many extra), in addition to storage media (like disks) that may retailer the knowledge you wish to home in your information lake.
For the reason that function of knowledge facilities is to supply area for deploying IT infrastructure, you may arrange the elements of a knowledge lake inside a knowledge heart.

However on this respect, information lakes aren’t any totally different from some other sort of IT workload – comparable to standard purposes or file programs – that may additionally reside on infrastructure hosted in a knowledge heart. There isn’t any particular relationship between information lakes and information facilities.
Word, too, that the majority information lake platforms summary the information surroundings from the underlying bodily infrastructure that hosts it. Which means that individuals who handle information inside a knowledge lake would usually don’t know which bodily servers are powering their workloads, or the place the disks reside that host their information. On this sense, the information heart that occurs to host a given information lake is irrelevant to the performance of the information lake itself.
Clarifying Knowledge Lakes vs. Knowledge Facilities
Finally, most information lakes depend on information facilities – aside from these hosted on on-prem servers exterior conventional information heart environments. That mentioned, information lakes and information facilities serve distinct functions, and understanding one doesn’t require experience within the different.
