Avanu Web-mux Cloud Load Balancers and Server Load Balancer
To diversify the services, an increasing number of organizations are looking to place workloads in the cloud. The cloud is ascalable, location-independent and ready-made data center,allowing the enablement of multi-layer application architectureson demand.
Within multi-layer application architecture, load balancingservices are commonly deployed between the Web, App,and Database tiers. Due to the request/receive nature of HTTP applications, the impact of a bad response substantially degrades the performance due to the quantity of how many requests are needed for a cloud web service.
An administrator can have one load balancer instance in front of all segments or multiple between segments, either Inline or one ARM Mode. Native cloud instances provide default load balancing but lack granularity of a full feature set required for advanced applications.
For this reason, load balancers with adequate feature sets are critical for cloud deployments and for the very functioning of cloud services.
What is the ultimate goal?
The primary goal is to accelerate web applications across all networks and device types to improve the user experience with fast page load times. All this should come at an affordable price.
To do this we need to send data efficiently, infrequently, and as little as possible. Sending data efficiently can be done with optimizing both the front end and back end TCP connections. Infrequent data transfers are fulfilled with caching and compressing transmits to as little information as possible.
The need for a new type of Load Balancer
Considering the rocketing traffic, vulnerability to DDoS attacks, and performance, it is crucial to choose a load balancer that is designed to outrun the shortcomings. The modern load balancer has been rolled out after extensive research and testing under current conditions. Therefore, it is certainly more in tune with the advances in application server software.
What a Load Balancer should have?
What should the perfect load balancing solution offer? Traditionally, load balancing has often been considered an expensive appliance with high ongoing maintenance and consistent training cost.
First and foremost, a load balancer should be affordable. Contrarily, many load balancing vendors charge high on appliances along with high ongoing maintenance costs. They have made the feature set so complex that consistent training is required on a yearly basis.
Load balancers offer a variety of features but it should only provide features matching with the customer’s requirements and at a low cost. The majority of networks work perfectly fine with an active — passive mode opposed to trying to set up clusters with complicated active — active deployments.
A load balancer should offer a customized operating system with performance oriented TCP/IP stack,advanced HTTP Parsing engine with appropriate feature set. It should handle significant amounts of traffic along with the capability to support periodic bursts without degrading the performance.
Load balancers are in a perfect network position to provide adequate security, fulfill regulatory compliances, and protect against the increasing level of DDoS attacks.
