Recently, we explained the concept of managed and unmanaged switches and their importance for CFTV/Network projects. However, there is a wide range of concepts, equipment, and services that must be considered in projects involving networks and internet transmission, and this is no different in a cloud-based CFTV project, for example.
That’s why, in this article, we’ll highlight the purpose of load balancers and their importance for a network project.
Service
Before diving into the concept of load balancers, it’s essential to understand what a service and, consequently, a server are. A server is hardware designed to provide services, enabling us to access websites and applications.
The server processes all requests made through a network, with companies like Google, for example, maintaining thousands of servers that handle simultaneous searches from thousands of users to return quick responses via the internet.
Unlike personal computers, servers must be available 24/7 to ensure applications function properly. To achieve this, technology companies implement various procedures to mitigate server errors and keep services available whenever a user makes a request. One such procedure is linking servers together to create a cluster, where multiple servers manage requests. This setup ensures that if one server fails, another can take over without interrupting the requested service.
Load Balancers
Now that we’ve explained the concepts of services, servers, and requests, we can define a load balancer as a connection manager—equipment consisting of hardware and software capable of creating routes, managing connections, and transmitting them in the most efficient way based on the availability of equipment and their connections.
In simpler terms, a load balancer distributes services and requests across multiple connections and servers, identifying which connection is fastest to process the request. If you have two internet links from different providers, the load balancer can check which connection is faster at the moment and send the request through it. Additionally, if one of the links becomes inactive, it can switch connections to prevent data transmission loss.
Load Balancers and Cloud-Based CFTV
One of the major advantages of having an effective network system in a CFTV project is ensuring 24/7 image transmission availability. With cloud services now well-established, a system that balances connections and determines the best way to transmit them to the cloud with minimal risk of data loss is indispensable, especially in professional projects.
