The global traffic on different websites can easily overload a single server and result in outages, and downtimes. That is why organizations generally adopt load balancing. It refers to the practices of distributing the workload across different servers to avoid overloading and outages.
Increased website traffic, concurrent connections, and heavy processes on enterprise applications can overburden the server and cause outages, downtimes, and slow speed. To overcome this issue, more and more enterprises are investing in load balancers that refer to the practice of appropriately distributing the load across different servers which saves any one server from being over exhausted. It ensures smooth workflow and prevents outages even during fluctuating needs.
There are a number of benefits of using server load balancers. here are some of the major advantages that make it almost mandatory to use load balancers for different enterprises
It can instantly scale up the volume of backend servers as your application needs increase which saves them from crashing. Likewise, when the requirements are reduced to normal levels, it automatically scales down the cluster of the servers thus saving you from spending on idle servers. This auto-adjusting feature enables you to enjoy reliable performance consistency during fluctuating needs while also economizing the costs.
Server load balancing are found to be much more efficient and reliable than conventional physical solution products.
Reliable support for concurrent connections
Supporting a massive volume of concurrent connections at once can have a telltale effect on the site performance and availability. The conventional solutions have limited capabilities which may sometimes not be enough. Server Load balancer, on the other hand, can support a tremendous number of concurrent connections at the same time without compromising on the deliverables.
Balance loads of your applications
Instant scaling of applications
Load balancers from the reputed internet companies allow you to multiply the RoI of applications by boosting their efficiency by instantly adjusting the ECS instances in the backend to align with your fluctuating enterprise needs. Increased ECS offers extra competency to match the scope of requirements and when things return to regular levels the extra ECS is automatically pulled back. In that capacity, it ensures a smooth and swift workflow.
Reduces or eliminates ECS errors
Sometimes the Elastic Computing Service (ECS) instance may misbehave and it can toss the entire performance by queuing up the inbound requests. Load balancer automatically drives these inbound requests to appropriate ECS instances to eliminate the friction and streamline the process.
Downtimes not only affect your sales and revenue but in the long term it also tampers with your site's reputation. There may be several factors behind downtimes. Overburdened servers are the major cause behind it. The irony is that such instances occur during peak sales or digital marketing campaigns when the traffic suddenly spikes up. It prevents you from benefiting from your digital investment. There might be more serious reasons behind downtimes like a DDoS attack that is aimed at crashing or freezing your site with an unmanageable amount of artificial traffic.
Protection against DDoS attacks
While cloud-based computing has made things easier and efficient for businesses it has also increased the security issues like DDoS. Every year a large number of digital businesses suffer due to DDoS attacks and significant instances are associated with cloud computing. Load balancers efficiently protect your site against such attacks by dividing the traffic among an adequate number of servers until you find the ultimate solution to foil these attacks.
Whatever the reason may be, the load balancers act proactively to smartly distribute traffic to another server that saves your site from downtime. Some load bankers also come with inbuilt security features against DDoS and other types of attacks thus increasing the security profile of your site.
Better alternative to maintenance on live server
Executing maintenance tasks over a live server causes network outages and downtimes. While you may always schedule such maintenance tasks and inform the customers in advance, a better solution would be to use a load balancing server instead. It allows you to perform maintenance tasks without disturbing the live server.
Likewise, during maintenance issues the load balancer redirects incoming traffic to another healthy server until the maintenance ob is over.
Optimizes overall deliverability for media sites
With increasing inclination towards video content and availability of sophisticated video editing solutions lots of websites are incorporating features like live streaming and short videos on their site. Apart from heavy resource needs, it also involves a frequent traffic exchange between clients and backend servers. It is often not always easy or possible to guarantee lightning-fast speed on such media sites.
One way to maintain smooth processing is to accelerate First Contentful Paint time. Load balancers with inbuilt Quick UDP Internet COnnection (QUIC) support can help in boosting FCP time to streamline the transmission flow for videos. It also helps in smart distribution of load during traffic spikes.
Ensures dynamic real-time scalability
Dynamic scaling of servers is another major benefit of load balancers which supports multiple phases of business growth. For instance, during the initial phase, you can rely on a single server while at the time of expansion and increased network needs the site is hosted across multiple servers. It frees you up from the worries of supporting your business expansion needs.
Accelerates speed and efficiency
User experience determines the success potential of your website and speed and stability play a vital role here. A majority of slow speed and downtimes instances can be resolved by making your server ecosystem more robust and responsive. Load balancer enables your ecosystem to instantly respond to fluctuating needs and thus helps in patching the performance gaps by increasing underlying capabilities on-demand.
Load balancers helps in evenly distributing the load across multiple servers to avoid overburdening a single server. In that capacity load balancing solutions ensures performance consistency, uptime and optimum speed of websites even during heavy instances and traffic spikes. It also saves websites from DDoS attacks. With a reasonable investment in load balancer the clients can protect the websites and online applications against the effects of server failures, traffic surge, usage fluctuations and concurrent connections.
