Times are changing. The application world is evolving in terms of how we service applications. It now requires a new approach to load balancing traffic. Applications are becoming more complex. What makes landscaping challenging these days is the connectivity of advanced gadgets like internal cameras, onboard computers, and many other wireless devices. Traditionally, we supported the monolithic single application per server design.
The single application per server was an apparent waste of resource triggering a variety of on-premise and cloud based multi-tiered applications. Each application stack has a number of tiers, potentially requiring load balancing functionality between each tier.
Microservices are also coming to this modern age. Microservices are fast and dynamic, individual services potentially located in different geographic areas posing additional challenges for load balancing and security. There is an increasing demand to support real-time interaction and multimedia content over a variety of network and device types.
Load balancers are ideal to execute the organization’s plan for end-user performance, reliability, availability, and scalability. AVANU offers the best of both worlds, lean load balancing at a low cost enabling business continuity and improving overall system performance. This enables the organizations to meet the most stringent Service Level Agreement (SLA) for the most complex Web application stacks.
AVANU has compiled all the best elements of a load balancer into a complete traffic management solution. Anyone can compile a load balancer but what matters most is the support and convenience of the entire solution.
AVANU experienced professional service team concludes that they are the market leader for lean load balancing at a low cost. Therefore, may it be in terms of performance or user-friendly execution or the cost effect, AVANU load balancer range offers an unmatched solution to your needs.
The average customer has high expectations and requires peak performance on all device types and networks. In this digital world, slow page loads are unacceptable and the customers expect services to work all the time.
Increasing IoT Traffic Volumes:
Traffic volumes are growing year by year. Gartner® predicts that The Internet of Things (IoT) is going to bring the number of connected devices to over 26 billion. Objects that were not necessarily connected to the Internet will now have IP reachability with the finesse to send and receive data with a variety of payload sizes.
IoT is all about data and is going to create a surge of data transfers through backend applications and
the central IoT control panels will be empowered to handle the flow.
Organizations are entering a new era of DDoS attacks. IoT not only increases the data quantity, but it also increases the DDoS landscape to billions of unsecured IoT devices. The network perimeter is no longer static, making it easier for cybercriminals to launch destructive DDoS attacks.

Load balancers prudently ensure the reliability and availability by monitoring the status of backend applications so that requests are successfully answered. Health checks determine the best server to service the inbound request, ensuring that the application will always be served from a healthy node.
There are multiple levels of health monitoring and the granularity intensifies with the level, depending on the application complexity. The type of check varies depending on the type of hosted application and the required complexity.
The most basic would be a simple PING testing network layer reachability. Or at a more advanced level,
the load balancer can inspect packet headers for specific keywords or request certain file types.
More complex health checks are required when the network stack is functioning but the problem lies somewhere higher up the stack, in the application layer. AVANU health checks are application specific. The WebMux examines server responses to validate whether it’s operational or not.
The WebMux health checks suit all application requirements - custom created scripts, HTTP Checks,
TCP connects, DNS, NTP, POP3, SNMP, and a basic level PING.
An HTTP health checker would examine the HTTP returns code to validate functionality. An HTTP 200
or 404 would deem that the HTTP service is fully operational. For additional granularity, the return codes are further tailored to specify what response codes are valid.
Generic TCP and UDP checks offer basic initial connectivity checking. They don’t go deep into the applications and simply look at the connectivity status. Custom scripting health checks are the most sophisticated and offer a lot of flexibility to meet non-standard health checking requirements.
AVANU custom scripting leaves it wide open for customers to create productive performance health checks. They can either come in the form of a Shell Script or C program.
They are useful when you want to check resources on the server that are not directly reported by the application itself. For example, a custom script is crafted to ensure that the CPU and RAM are at a certain level while breaking a predefined threshold or it would be considered an unhealthy server.
Scripted health checks are also useful to test remote servers, for example, a database holding structured data used by servers.
The new generation WebMux hardware models combine today’s higher performing components in a 64-bit architecture to provide the high performance and reliability necessary to overcome continuously evolving network challenges,” says Pamela Sun, President of AVANU. Service demands on today’s Internet have increased from the explosion of new media trends. One such trend is the proliferation unified communications (UC) platforms from the likes of Microsoft®, Oracle®, IBM®, Cisco®, HP®, Avaya®, and Siemens®, which require the services of a highly efficient, scalable, and secured load balancing solution. WebMux provides the high capacity, reliability, and availability to manage, control, and secure local traffic at IP layers 4 through 7 for TCP- and UDPbased applications such as these.
AVANU’s WebMux is developed and manufactured in the United States complying with the Trade Agreements Act (TAA) guidelines. Hardware appliance models supports dual hot-swap power supplies and come with a 2-years product warranty and 1-year free technical support. WebMux Virtual appliances for Cloud computing environments (such as VMWare®, Microsoft Hyper-V®, Oracle VirtualBox®, and Citrix XEN®) also come with 1-year free technical support. Both WebMux hardware and Virtual appliances feature firmware v13.0. New WebMux hardware models will begin shipping in July 2017. Find WebMux information at www[dot]avanu[dot]com. Questions?
