REDIS – EXPLAINED IN SIMPLE WORDS

Database, may be described as a store room in which data is stored. Just like a store room has the options of having shelves and metal rack, sometimes even steel lockers, a database also can store data in different ways. The data could be stored in tables or documents or in certain structure which will just make it easier to work with the data.

In Redis, the formats that it uses to store and work with data inside it are various such as lists, strings, hashes, bitmaps ,sets, sorted sets with range queries, hyperloglogs, geospatial indexes, and streams.

In addition to that the different types of structures of data that are inside a database, a database may also differ based on its location.

Now your storeroom could be on the top most floor or in the office room where most of the work is done, and each of the possible location could have its advantages and disadvantages depending upon the kind of work you would need the data for , the situations in use and various other factors.

Similarly an In memory database is a database that is stored in the main memory and Redis is an in-memory database.

To top it off , Redis is an open source, meaning it can be easily accessible by anyone who wants to use it as a cache and a database. It also acts as a message broker , meaning facilitating the communication among various applications, systems and services.

And cache is more like a database , except for it is much more used to store data that can be readily accessed and modified .

So to recap

Redis is a data store , which can be used as database, cache and message broker. It is also an open source and an in-memory database.

A Cerelac definition of DevOps

DevOps Meaning

The Development team (Dev) and Operations(Ops) team are 2 of the many teams that are involved in completion of a successful software project.

The Dev team constructs the software project and the Ops team deploys and manages that software project in its intended environment, ready for the application now to be used for its intended purpose.

Rather than working as two separate units, these two units works as one. instead of being Silo-ed , that is , instead of treating the software project information of the Dev and Ops separately , there is a possibility of co-treating this software application information , thus unifying the efforts both the teams.

Why DevOps?

In world where dev and ops functions separately, consider the software application in the hands of the operation team , when deploying or even while managing the application , issues may arise for which the application now has to go back to Dev team . This causes reiterated usage of resources such as time, money and human resources ( such as the developers,the testers and the operation engineers ) .

This would not only harm the competitiveness of the company but also cause delay on the client side who is waiting for the application to go live without any problem.

Deadlines increase , possibly giving more room for dissatisfaction for the client as well as posing hindrance to all the upcoming projects that a company might have in its pipeline.

Therefore implementing DevOps is always a positive step for a company as it results in producing reliable software products that has been deployed at a competitive pace , ensuring client satisfaction and increased efficacy of the organisation.
