...network managers be slow, painstaking process for companies choosing the many advantages of the network-based, load-balancing switches.
By developing an application to manage the time-consuming coordination between these two teams, developers can self-serve their needs more quickly, network managers can save valuable time previously spent performing manual tasks, and companies can experience more flexible application deployment and updates.
Budget-conscious IT departments can also save enormous amounts of scarce financial resources and time. On a network basis alone, conservative estimates show that companies can save nearly $20,000 per network engineer per year in time spent managing this process by building a very basic application deployment-and-update application. At the same time, the client experience is improved through better orchestrated application deployment.
Summarily, an opportunity now exists to help automate the process of deploying and updating Java applications in order to save development time, ease frustrations of deployment, and gain flexibility to deploy new applications on demand while offering the best client experience.
The Current State of Enterprise Applications
It should come as little surprise to developers that as Web applications have flourished, so have demands on the application servers required to deliver them. The days of deploying an application to one server and hoping it delivers performance and reliability are a thing of the past.
As a result, applications are typically deployed in a redundant fashion across multiple identical application servers. This ensures that the application is available when requested, even if one application server is out of service or experiencing technical difficulties. Traditional "load-balancing" solutions help virtualize a specific application IP address so that when people access a URL or IP address, the load balancer determines which redundant server is best suited to accept and respond to the application request.
The advantages of load balancing are significant. Most serious Web sites and e-business applications today employ some form of load balancing because it ensures a predictable client experience. Load-balancing solutions also help increase application performance by distributing requests to the best performing servers, in some cases, they can deliver more cost-effective applications due to lower server license costs and server expenditures.
When it comes to application reliability and load-balancing options, companies usually consider two alternatives for increasing the reliability and performance of their applications. One choice is software load balancing, which is included as a feature with most Java application servers. In this scenario, application servers help distribute load by utilizing some form of clustering or "round robin" load balancing. While this capability is usually included in the price of application servers, it comes at a cost to server...
