Is it Load balancer is a required component ?

Hi @Sino,

It is not a required component, It totally depends on the load and the number of request on the server. For the performance enhancement, we use many approaches like external caches, for example, APC, Memcached etc when we have the webserver and DB on the same server.

On the other side, we can also use the load balancer in which we can place our database on the different servers and according to load, we can pass them to the appropriate server. 

All the above approaches totally depend on the situation, Like currently, I am working on a project in which neither any load balancer nor any external caches are required. Sugar instance is on the 'ABC' server DB is on the 'XYZ' server and Elasticsearch is on some other server.

Hello Enrico Simonetti and Maryam Aslam

Thanks for sharing your architecture level experience and knowledge.

What I understand and conclusion is Load balancer is not a required or mandatory component of architecture . It will only required based on the load of the server.

The above mentioned components by Enrico Simonetti are necessary or required for a  typical architecture.

Is it my understanding is in sync ?

Hi,

Yes, you understand correctly. But according to my point of view Cache is also the optional component because if the server has no too much load and DB and Elasticsearch are on the different servers then it will work like a charm without any external cache because due to Elasticsearch results already retrieved very fast.
