Easy to integrate with third-party tools to boost performance and improve productivity. Founded in the year , by Imperva based in Redwood Shores, California, it is a robust and reliable load balancer used by over 3 million websites including giant brands like Hitachi, Siemens, Garmin, and others. It is a real-time server monitor best suited for network administration because it allows real-time traffic monitoring and load balancing distribution.
It is a high performance down to tech network administration tools plus its ability to serve millions of requests a second among other outstanding features. It has a huge market base with gigantic brands like Instagram , Tumblr , Github, Reddit, etc. Its core features include high security , sterling performance, and high availability. It is developed in Go programming language hence highly compatible with Ubuntu. Neutrino can support the least-connection and a round-robin algorithm packed with the following features; canonical names, context-based, L4 using TCP port numbers.
It has one major advantage over HAproy; L7 switching. Founded by InLab Networks, is an open-source load balancer, simple but powerful, bundle with the following heart throbbing features; TCP proxy round-ribon supports IPV6 from the listening end, demonstrates all other features available on LB. Trust me you. It can detect and alert us on failed servers and distribute traffic to available service, a great cushioning failover trait.
A high availability system reliably provides an acceptable level of service with minimal downtime. To provide high availability, NLB includes built-in features that can automatically:.
Scalability is the measure of how well a computer, service, or application can grow to meet increasing performance demands. For NLB clusters, scalability is the ability to incrementally add one or more systems to an existing cluster when the overall load of the cluster exceeds its capabilities.
To support scalability, you can do the following with NLB:. Balance multiple server load requests from the same client or from several clients across multiple hosts in the cluster. Enable high performance and low overhead through a fully pipelined implementation. Pipelining allows requests to be sent to the NLB cluster without waiting for a response to a previous request. Specify the load balancing behavior for a single IP port or group of ports by using port management rules.
Define different port rules for each website. If you use the same set of load-balanced servers for multiple applications or websites, port rules are based on the destination virtual IP address using virtual clusters. Direct all client requests to a single host by using optional, single-host rules.
NLB routes client requests to a particular host that is running specific applications. Enable Internet Group Management Protocol IGMP support on the cluster hosts to control switch port flooding where incoming network packets are sent to all ports on the switch when operating in multicast mode.
NLB logs all actions and cluster changes in the event log. NLB is installed as a standard Windows Server networking driver component. The following figure shows the relationship between NLB and other software components in a typical configuration.
Provides Network Load Balancing Tools to configure and manage multiple clusters and all of the hosts from a single remote or local computer.
Enables clients to access the cluster by using a single, logical Internet name and virtual IP address, which is known as the cluster IP address it retains individual names for each computer.
Define a load balancing rule to send traffic that arrives at the front-end IP to the back-end IP. In this example, the back-end pool receives TCP traffic to port Use the following example to define a load balancing rule:.
Add the load balancer configuration to Network Controller. Use the following example to add the load balancer configuration to Network Controller:. In this example, you configure SLB with a back-end pool for providing outbound NAT capability for a VM on a virtual network's private address space to reach outbound to the internet. Follow the next example to add the network interfaces to which you want to provide internet access.
In this example, you add network interfaces to the back-end pool. You must repeat this step for each network interface that can process requests made to the VIP. You can also repeat this process on a single network interface to add it to multiple load balancer objects.
For example, if you have a load balancer object for a web server VIP and a separate load balancer object to provide outbound NAT. Get the network interface and add the backendaddress pool to the loadbalancerbackendaddresspools array.
