Microsoft Network Load Balancer Alternative

What is Microsoft Network Load Balancer

Microsoft Network Load Balancing (NLB) is a feature offered in Windows Server that enhances the performance and availability of applications by distributing incoming network traffic across multiple servers. This ensures that no single server is overwhelmed by requests, improving both scalability and reliability. Microsoft Network Load Balancing operates at the network layer, specifically Layer 3 and Layer 4, and uses algorithms such as round-robin or affinity-based methods to evenly distribute the workload. By using Microsoft Network Load Balancing, administrators can ensure that client requests are handled efficiently, enhancing overall system responsiveness.

The Microsoft Network Load Balancer also provides a critical feature: fault tolerance. If a server within the load-balancing cluster fails, the Microsoft Network Load Balancer automatically detects the failure and redistributes traffic to the remaining servers in the cluster. This seamless traffic redirection ensures continuous service availability without the need for manual intervention. Unlike hardware-based solutions, the Microsoft Network Load Balancer is a software-based tool, offering a cost-effective and easily configurable way to manage network traffic distribution within Windows environments.

What is RELIANOID Load Balancer

RELIANOID® is an Application Delivery Controller and Load Balancer that ensures high performance and security of IT services on a massive scale.

The RELIANOID Load Balancer offers several advantages over Microsoft’s Network Load Balancer, particularly in terms of flexibility, security, and advanced features. RELIANOID is an open-source solution that supports both application-level and network-level load balancing, allowing more control over traffic management, SSL offloading, and security features like firewalls. It also integrates easily with various systems, offering a highly customizable interface, whereas Microsoft Network Load Balancer is more limited to network-level distribution and basic fault tolerance.

Additionally, RELIANOID provides better scalability and redundancy options for enterprise applications, making it a strong contender for organizations needing more than Microsoft’s basic load balancing functionalities. Its robust monitoring, reporting, and ease of use through web-based GUI make it a superior choice for environments requiring advanced load balancing configurations​.

Microsoft NLB’s Strengths

Microsoft has significantly augmented its investments and dedication to providing enterprise Application Delivery Controller (ADC) services, and we expect this dedication to persist.

In the Azure ecosystem, essential Application Load Balancer (ALB) services are bundled at no extra cost with Microsoft’s “standard” tier of virtual machines.

Microsoft’s Application Gateway (AAG) service has the capability to balance traffic directed towards servers located beyond the server cloud, including on-premises infrastructure.

Looking ahead, it is foreseeable that Azure’s ADC capabilities will be expanded to support on-premises workloads, working in tandem with Azure Stack.

RELIANOID’s Strengths

Expert and skilled R&D professionals accomplished in Zevenet and Zen Load Balancer, departing from an Open Source technology with no vendor lock-in and broad platforms integration (hardware, virtual, bare metal and cloud), bringing security, performance and readiness.

Cost-effective solutions with no constraints on products and services, tailored to the needs of midsize companies as well as large enterprises.

Protocol Versatility adapting and managing diverse network environments and protocols (UDP, TCP, HTTP/S, SCTP, SIP, T/FTP).

L7 and L4 Performance managing over 140K concurrent users at Layer 7, while at Layer 4, it efficiently handles more than 10 million concurrent users, all with just 2 dedicated cores.

High Availability witha automatic real time stateful cluster replication.

Security and WAF improved as it incorporates an Intrusion Prevention and Detection System (IPDS) and also an integrated Web Application Firewall (WAF). It actively safeguards web applications against specific threats while providing real-time IP blacklisting, Denial of Service (DoS) protection, and support for black and whitelisting.

User-friendly interface designed for both DevOps and SRE professionals, ensuring ease of use in managing and configuring systems.

Automation thanks to its fully programmable and robust REST+JSON API.

Microsoft NLB’s Weaknesses

The Dashboard (user interface), can be rather complex. It may require users to navigate through multiple pages to access comprehensive system information, including charts and graphs.

Deploying third-party applications, especially when it involves setting up a virtual machine using a VHD file, can be challenging. The available resources for supporting this specific VM deployment are often insufficient.

Authentication controls, such as conditional policies and multi-factor authentication, can occasionally prove to be intricate for end users to configure and use effectively.

RELIANOID’s Weaknesses

Emerging brand, challenging the ADC and Load Balancing market, operating as an open-source company.

Still in the process of building a significant presence. It must expand its partnership network more extensively.
