) Good luck and please post your findings here if you are unsuccessful.Being familiar with both the limited resources and key technologies that influence a web application's performance and scalability, its time to analyze how both resources and technologies influence the basic techniques applied to solve performance and scalability issues. User demand builds up over time, which is one of the primary reasons performance and scalability issues start to arise.When a web application launches, it's rarely afflicted with performance and scalability issues to the point of becoming unusable. It's only after a gradual increase in users, which in turn increases the amount of data, processing power and other resources needed to keep a web application running smoothly, that performance and scalability issues start to appear.The topics of performance and scalability in web applications are always interesting because they are multidimensional.They can be tackled on multiple fronts, from the operating system, programming language, web server, permanent storage system or other parts that compose a web application.

And can also be addressed in various ways, from simple changes made to source code or configuration files, to deep design choices which are best contemplated from the outset to avoid scraping parts of an application that don't perform or scale at a given threshold.In order to classify the parts of a web application's afflicted by performance and scalability issues, I will use the following three-tier classification structure throughout the book: To further illustrate what's implied by each of these tiers, table 4-1 has several examples of a web application's parts and how they relate to this three-tier structure, including a series of associated performance and scalability techniques.Grasping how a production environment is set up for running web applications is an important aspect of understanding the constraints and benefits of using performance and scalability techniques in each of these three tiers. Handel zwischen privatpersonen telefonbuch. As you learned in the previous chapter, virtualization has created a blurry line for a production environment's hardware and its resources (CPU, Memory, Bandwidth and I/O capacity).But whether a web application relies on virtualization or not, at its initial stages it generally makes sense to deploy everything that makes up a web application -- core programming platform (Java, Ruby, Python or other), web framework and permanent storage system -- as if it were running on a development workstation.Technically speaking, all the web application's tiers hosted on the same node or box, as illustrated in figure 4-1 .
