Computer networks work a lot like railway systems. Many trains, each with many cars, share a small number of tracks, so the system has to keep them moving efficiently. Efficient operation means the trains never collide and always reach their destinations on time.
Computer traffic within or across networks must handle billions of bits of information. That data speeds across cables and lines, and it must reach its destination on time. Networks and algorithms use many sophisticated methods to handle small- and large-scale transmission, but the most effective way is through load balancing. Hardware load balancing is an older option, while a newer, more cost-effective option is cloud load balancing.
Hardware Load Balancing Defined
A hardware load balancer is a physical device that helps distribute or route web traffic across multiple network servers. It weighs several factors when it makes that decision, such as:
- Proper utilization of the servers
- The number and quality of the connections between the servers
- The performance of the servers
- The way the traffic is routed (the algorithms that manage the transmission of information)
A sophisticated calculus balances these factors so the system reaches optimal performance levels.
Effective hardware load balancing keeps every server working at the right level and maximizes computer bandwidth. Good hardware load balancing also helps minimize downtime, and it can even help protect against malware and cyber-attacks.
Cloud Load Balancing Defined
Cloud load balancing, also called Load Balancing as a Service (LBaaS), is a modern alternative to hardware load balancing. Outside data centers manage and balance the web traffic instead of the business handling it internally. Cloud load balancing is very desirable for large, distributed environments.
Hardware Load Balancing vs. Cloud Load Balancing
Each type of network traffic balancing has pros and cons. A knowledgeable data service representative reviews factors with you, such as the size of the business and the type of business involved. Several key factors favor cloud load balancing over hardware load balancing:
- Cost factors. Cloud load balancing is often more affordable than multiple servers because of the high cost of hardware. Capital and maintenance costs are generally much lower than with hardware load balancing.
- Global Server Load Balancing (GSLB). GSLB manages traffic across the planet. If a company has business relations in different nations, it needs to manage network traffic across those nations. Cloud balancing handles disasters better by transferring traffic to a foreign server. It also handles daily performance issues better than hardware load balancing.
- Ease of setup and use. Cloud load balancing is a clear choice here.
- Scalability. Cloud load balancing is often more scalable, so it is easier to add capacity when new network traffic demands arise as the company grows.
- Compatibility. Hardware load balancers generally work only with other hardware load balancers. Cloud load balancers, however, work with both types, hardware and cloud.
Both hardware and cloud load balancing need to handle distributed algorithms, which manage network traffic. Common types include round-robin, the lowest number of connections, and the least pending requests.
You should also review network layer load distribution, application layer load distribution, and reliability.
