Even if your site suddenly goes viral or you run a flash sale, your servers won’t buckle under peak-traffic pressure—the load balancer spreads requests evenly, preventing latency and outages. It shields you from overloads, is dependable in operation and simple to configure. A load balancer is the cornerstone of a stable infrastructure.
At peak times servers risk being overloaded, which slows down page‑load speed and can lead to customer loss. Load balancers solve this problem by distributing traffic evenly. Fast, reliable web services help you attract more customers and increase sales.
Cyber‑attacks can be catastrophic for companies that process personal or other sensitive data. Load balancers boost protection by blocking DDoS attacks and filtering traffic, ensuring continuous operation and maintaining customer trust.
Start‑ups and small businesses with limited budgets use load balancers to optimise server utilisation and cut infrastructure costs, thereby increasing their competitiveness in the market.
For medical record systems or organisations with critical infrastructure that require zero downtime, a load balancer monitors server health and automatically redirects traffic if one of them fails.
A load balancer is a cloud‑infrastructure service that distributes traffic across multiple servers (instances) to ensure optimal resource utilisation and achieve high application availability.
The balancer also performs additional functions such as health checks and rerouting requests to another server if the current one fails.
Best suited to applications that handle simultaneous, time‑consuming requests (e.g. CRM systems or complex web services).
Least Connections distributes traffic by directing new requests to the server with the fewest active connections, reducing the risk of overloading any single server.
Ideal for blogs, news portals or corporate sites with standard content pages.
Round‑robin distributes traffic evenly without considering active connections or server capacity, because requests generally have similar characteristics and require little processing time.
Perfect for resources that need session stickiness, such as online shops where customers add items to a basket and place orders.
IP Hash guarantees connection to the same server throughout a session, preventing data loss.
Cost reduction: in most cases the financial and time costs of LBaaS are lower than those of hardware devices.
Global availability: with GSLB, users connect to the geographically closest server with minimal latency and guaranteed high availability, even if a server is offline.
Scalability: LBaaS lets users quickly and easily scale load balancing to handle traffic spikes without manually configuring additional physical infrastructure.

What is a Cloud Load Balancer?
A Cloud Load Balancer is a tool that distributes incoming network traffic across multiple virtual machines within our cloud infrastructure. This ensures that no single machine is overwhelmed by high traffic volumes. It also provides fault tolerance—should any virtual machine fail, the load balancer will redirect traffic to the remaining active machines, keeping your services operational.
Can I specify how traffic is distributed among virtual machines of different performance levels?
Yes, you can assign a weight to each virtual server to define the proportion of traffic it handles. For example, if one server has a weight of 1 and another has a weight of 2, the first will handle one third of the traffic, while the second will handle two thirds. Weights can range from 1 to 256, and setting a weight to 0 will prevent the server from receiving new connections.
How can I determine the real IP address of requests received by the balancer?
To find the original IP address of a request, you can utilize additional HTTP headers:
Can the Cloud Load Balancer be used with dedicated servers?
No, the Cloud Load Balancer is specifically designed for virtual machines within our cloud infrastructure. For dedicated servers or external virtual servers, our Fault Tolerant Load Balancer would be more appropriate, although it does not currently support servers from other providers.
What happens if a server in the load-balanced pool fails?
If a server fails, the load balancer automatically redistributes traffic to the remaining servers. While there might be minor delays in rerouting, this mechanism generally prevents significant downtime. However, if the surviving servers cannot cope with the load, this may lead to reduced performance or temporary service disruptions.
Does a cloud load balancer offer protection against DDoS attacks?
While a cloud load balancer can help mitigate the impact of DDoS attacks by dispersing traffic across multiple servers, it is not a full defense mechanism. For comprehensive protection against severe DDoS attacks, specialized DDoS protection services are recommended. The load balancer does offer some level of initial filtering which can remove certain types of malicious traffic.
