Business Benefits of JetNexus Loadbalancer TrafficManager

Application integration and control

JTM provides all the functionality you need to secure, manage and optimise all the high-level application traffic on your network from one central point. Including powerful, intuitive TrafficScript routing language you can apply your unique business logic and solve problems as they arise without the need to rely on external technical back-up.

Pay as you grow scalability

TrafficCluster scalability enables you to deploy JTM units in any combination and volume giving you the flexibility to have as many layers of resilience as you need. With TrafficCluster flexibility you can be sure your JTM deployment can grow in line with your changing business needs.

Application acceleration

JTM's unique technology accelerates most applications many times over by simply by being placed in front of them. Combined with offload, processor capabilities you'll see greatly enhanced performance, capacity and return on investment from your key applications.

Active monitoring

JTM delivers real time reporting and historical graphs of your application activities via a web based interface and SNMP. Combined with one click self diagnosis you can plan future capacity requirements, analyse traffic trend and isolate faults quickly.

Offer differentiated services

With capability for content caching, service level monitoring and bandwidth management, JTM allows you to apply relevant service levels for different groups of customers to ensure your most profitable traffic receives the quality of service it demands.

Traffic Management

Resilient Load Balancing - For effective load balancing its essential to reconfigure and understand each application request and response. JTM draws on a variety of intelligent load balancing algorithms within its arsenal to read and interpret requests before load balancing them across a pool of servers. Deployed in a horizontal scalable cluster for fully fault tolerant load balancing, JTM seamlessly handles server failure by redirecting traffic to a different, healthy machine ensuring continuous availability of your Web-based applications.

Ease of use - JTM provides a secure web based administrator interface that's both simple and intuitive yet powerful and flexible. With installation typically completed within an hour, you'll quickly regard JTM a key asset to your network.

TrafficScript - As the most powerful traffic management script language available today, TrafficScript possesses unlimited content inspection depth to read incoming requests and outgoing responses for any protocol. By seeing the whole picture, JTM translates your business rules into accurate routing decision. As a true language, TrafficScript is easily accessible to anyone with JSP, ASP, PHP or Perl skills.

Session Persistence - Complex applications such as those employed by e-commerce organisations store large amounts of information about users. Typically these are stored locally and do not run well in a clustered environment. To ensure sessions are automatically honoured, JTM session affinity enables individual URL mappings to be specified as sticky and directs requests to the same cluster of machines.

Control API - JTM provides an open standard, SOAP based control API. Manual configuration tasks can now be automated by JTM which can include: detection of application based attacks, applying policy changes to network firewalls or deploying more server capacity for periods of high loads and more.

Enforce Service Level Agreements - JTM enables your business rules to be applied to traffic management, closely monitoring how services perform against defined SLAs for a rapid health check assessment of application services. Unique functionality allows you to define response times for server requests and even different response times for different groups of customers. When response times fall outside parameters, JTM takes whatever actions are needed to enforce your rules.

Optimisation

Surpassing all rival traffic management solutions price:performance ratio, JetNexus Traffic Manager unique process architecture handles more transactions, more content inspection rules, more application services and more back end servers.

Controlling your bandwidth - Popular, low revenue services can ‘steal' available bandwidth from high profit generating services thereby compromising the quality of service your paying customers receive. To avoid this happening, JTM lets you define a maximum bandwidth limit on each service to ensure mission critical services always have sufficient bandwidth.

How fast is JTM? - JTM is designed to extract the best possible performance from your hardware. Independent benchmark performance by broadband testing demonstrate a single JTM running on a standard dual AMD Opteron can achieve: over 87,000 requests per second, over 20,000 content compression operations per second, over 2.5 GB throughput per second with 4,500 SSL transactions per second. With comparative performance to competing products of nearly three times the cost, JTM demonstrates unbeatable cost effectiveness.

Web Content Caching - By storing local copies of frequently viewed web pages, images and other content, JTM greatly reduces the number of requests forwarded to your servers. As a result back-end application load, data transmit times and bandwidth usage are cut giving you enhanced value from your existing web or application service cluster.

Integrated Application Acceleration - As a non-intrusive addition to any network, JTM requires little or no configuration work and wastes no time in accelerating your existing application infrastructure by:

• Acting as a data buffer between the application server and Internet connections to ensure applications see only quick requests over a reliable LAN.
• Preventing excessive load on any one application server through effective cluster management and server selection.
• Offloading CPU intensive tasks such as SSL and XSLT from the application server onto JTM itself which has been optimised for those tasks.

How JetNEXUS Traffic Manager Works

• JTM can be deployed in any number and combination of active and backup units to protect you against compound failures.
• Each JTM unit monitors the health of all the other units in the traffic management cluster and of the back-end servers.
• Incoming traffic is accepted by a virtual server.
• TrafficScript rules are used to inspect the request and send it to an appropriate server pool.
• Traffic is distributed across the server pool using one of a variety of load balancing algorithms.

Security

Without a cohesive application security policy you become exposed to wasting time and money patching security holes and recovering from security breaches.

With secure, out of the box protection from intrusion, JTM is a proven solution to your security needs. Including the latest encryption technology, JTM provides peace of mind for you and your customers.

Security by default - JTM has been rigorously tested to ensure no vulnerabilities are introduced to your network. Using a variety of sophisticated techniques you can be sure the moment it starts, JTM is a secure, no-risk enhancement to your network.

Service protection - With unique protection against Denial of Service attacks, JTM transparently shields your Web infrastructure. Proactive counter-measures can easily be deployed across your cluster helping you achieve continuous availability. Plus, with in built monitoring and threat analysis you can keep up to date at any time.

SSL decryption and re-encryption - The reputation of an organisation can depend on how well it safeguards information but ensuring security of internet traffic using SSL connections can cripple server performance. With native SSL decryption and re-encryption combined with its efficient and cost-effective process architecture JTM avoids these problems.
