A high performance Load Balancer
Zeus ensure the successful delivery of online services cost effectively from any deployment environment – physical, virtual or cloud. Zeus Load Balancer is a powerful load balancer that grows with your traffic management needs. It is a cost-effective starting point for adding load balancing and resilience to your services, with a smooth upgrade path to Zeus Traffic Manager to scale as your services grow. With integrated SSL, WAN offload, and content compression, Zeus Load Balancer dramatically accelerates many networked applications.
Zeus Load Balancer accelerates applications in a number of ways:
- SSL offload: by processing SSL traffic, Zeus Load Balancer frees up application servers to spend more time doing their own specialist tasks
- WAN offload: by accelerating and condensing the number of incoming connections, Zeus Load Balancer enables your applications to handle more requests with fewer connections
- Content compression: by compressing content before it is sent to clients, Zeus Load Balancer reduces the burden on your networking infrastructure
Using Zeus Load Balancer to manage your applications can have a very positive effect on their performance; using the WAN offload capabilities alone, Apache can be accelerated by as much as 100 times, and application servers such as IBM WebSphere and BEA WebLogic by as much as 10 times.Zeus Load Balancer will get the most out of the hardware it is deployed on, taking advantage of 32-bit and 64-bit optimizations where available. It was independently benchmarked by Broadband-Testing to achieve over 4,500 SSL transactions per second on a standard dual AMD Opteron server. Zeus Load Balancer is a pure software application. It is built on top of the same high-performance core architecture as the award-winning Zeus Web Server and Zeus Traffic Manager.
As a result of its application awareness, Zeus Load Balancer is best deployed close to the servers it is managing.
If you need to make sophisticated internet traffic management decisions, and need to closely monitor the health of the services you are hosting, Zeus Load Balancer is optimally suited for this environment. Zeus Load Balancer offers far more than a traditional load balancing solution. Its traffic management capabilities bring much more flexibility and fine-grained application layer control than is possible with most pure- hardware load balancing solutions. Because Zeus Load Balancer supports a range of platforms and operating systems and runs on commodity hardware, its performance can easily and cost-effectively be grown as required.
The basic architecture of a load-balanced server farm consists of one or more front-end Zeus Load Balancer machines, a number of back-end server machines. The Zeus Load Balancers can be administered from either unit. The front-end machines should be able to route traffic from the Internet to the back-end machines, and back from the back-ends to the Internet.
Zeus Load Balancer is available in single and resilient cluster configurations. Clustered configurations offer the benefits of increased capacity and fault-tolerance to front-end failures.
Zeus Load Balancer Benefits at a glance:
- Improves Performance - With integrated SSL, WAN offload, and content compression, Zeus Load Balancer dramatically accelerates many networked applications.
- Creates Resilience - Zeus Load Balancer can be deployed in active / active high-availability pairs for load balancer resilience, and creates fault-tolerance for your back-end servers.
- Adds Intelligence - Content inspection rules allow you to send requests for certain web pages to specific groups of servers.
- Improves Reliability - By continually monitoring the health of your back-end servers, failed servers are automatically detected and removed from the cluster until they recover.
- Ease of Use - Zeus Load Balancer takes minutes to install and configure, and includes a secure, web-based graphical user interface which provides you with visual alerting, health monitoring and cluster diagnostics.
- Advanced Load Balancing Algorithms - When deciding which is the most suitable server to send a request to, Zeus Load Balancer makes use of several advanced algorithms, bringing extreme efficiency to content delivery.
- One-Click Session Persistence - If sticky sessions are required for your web application, just turn on session affinity with one click.
- Connection Draining - Allows you to remove back-end servers from your cluster safely without disrupting any users' sessions.
