Load Balancing in Cloud Computing

Load balancing is a theory combining 2 or more connections in one system. Which means also combines 2 speed or more to the connection. And balance the traffic on the interface connection to one another.

In this case I use Mikrotik.

Imagine if you have two speedy connection but you haven't join with load balancing, don't expect to get 2mbps speed (I assume of 1 my speedy speed is 1mbps). In contrast to when we use load balancing, speed can be obtained doubled.

Load balancing can also be regarded as a technique to balance the load of bandwidth internet network two or more of the same or a different ISP, and used for a LAN network. That is, the two lanes merged into an internet router, and then routed to the LAN network with the goal of maximizing the performance of the LAN bandwidth.

I would think that we have two internet connections, eg modem1 and modem2, also has a mikrotik router. Make sure that the PC / Mikrotik router has 3 ether. The requirement is, ether for modem1, ether for modem2 and ether for your client.

In order to facilitate easy setting step, we should change the IP modem1 and modem2 as following:

Modem1: 192.168.1.1/24, modem2: 192.168.2.1/24. IP Mikrotik for the client interface: 192.168.0.1/24. All of this IP can be set according to what you needs.

Setting in Winbox interface as: ether0 = client, ether1 = modem1, ether2 = modem2.

We continue to set Mikrotik, through the new terminal, we follow these steps:

Setting IP Address

/ Ip address add address = 192.168.0.1/24 network = 192.168.0.0 broadcast = 192.168.0.255 interface = client

add address = 192.168.1.2/24 network = 192.168.1.0 broadcast = 192.168.1.255 interface = modem1

add address = 192.168.2.2/24 network = 192.168.2.0 broadcast = 192.168.2.255 interface = modem2

IP Route

/ Ip route

add dst-address = 0.0.0.0 / 0 gateway = 192.168.1.1,192.168.2.1 check-gateway = ping

Setting Firewall: NAT and Mangle

/ ip firewall nat

add chain = srcnat out-interface = modem1 action = masquerade

add chain = srcnat out-interface = modem2 action = masquerade

/ Ip firewall mangle

add chain = input in-interface = modem1 action = mark-connection new-connection-mark = modem1_conn

add chain = input in-interface = modem2 action = mark-connection new-connection-mark = modem2_conn

add chain = output connection-mark = modem1_conn action = mark-routing new-routing-mark = to_modem1

add chain = output connection-mark = modem2_conn action = mark-routing new-routing-mark = to_modem2

Routing to mangle

/ Ip route

add dst-address = 0.0.0.0 / 0 gateway = 192.168.1.1 routing-mark = to_modem1

add dst-address = 0.0.0.0 / 0 gateway = 192.168.2.1 routing-mark = to_modem2

For the successful setting up here, already successful means of load balancing. Usually the IP route, the IP will appear blue, which is usually confusing, whether we fail or how the settings. But don't worry, this usually normal after our network are connected correctly to the PC which we install the Mikrotik router. If it still blue, it means the connection from the modem is not connected to the Mikrotik router.
