hi everyone welcome back again so in this video we will start with server
load balancing
so what is load balancing, as we learn in our last video load balancer distribute the
clients requests among the multiple server devices, leave will leave the link in
cart please check that, there are some terms and terminology that we need to
understand before moving further client, node, pool, pool member and virtual server, what is the client?
this is the client, it's sitting at external side of F5 load balancer this
is the internal side this is the external side client is the machine which
send connections or request to a f5 load balancer for a web server pool this
client send connections or send request to F5 load balancer to access
this web server pool, there are some applications or services running on this
server devices and the clients want to access that services that's why it sending a
request on f5 load balance
what is the node node is the individual device individual server device in a
server pool configured on a f5 load balancer a node can be a member of
multiple server pool it can be a member of FTP pool it can be member of web
server pool at the same time and node identify on its IP address like here
node 1 IP address is 10.1.1.10 node two IP addresses 10.1.1.15 note 3 IP address is 10.1.1.20
what is the pool is the group of server devices
configured on a fire load balancer for certain services or applications and
we identify the pool on its service or application so like here this is the web
server pool, what is the pool member? when a node we assign to a specific pool then
it become a member of that pool that is pool member
and pool member identified on its IP address and service port like here this
server device having the IP address 10.1.1.10 and it's : 80
this service belongs to this server pool that's why this node belongs to this pool
what is the virtual server virtual server is hypothetically configured on a
f5 load balancer and clients which are connected on external side of a f5
load balancer send a request on this virtual IP virtual server IP address to
access services or applications running on this server devices this virtual
server identify with its IP address and service port like here virtual
server is having IP address 172.16.1.150:80
that's it guys in this video thanks for watching and subscribe to stay tuned
I'll see you in next video
