Hadoop is an ecosystem of Apache open source projects and a wide range of commercial tools and solutions that fundamentally change the way of big data storage, processing and analysis. The most popular open source projects of Hadoop ecosystem include Spark, Hive, Pig, Oozie and Sqoop.
The Big Data refers to a collection of large datasets that cannot be stored, processed or analyzed using traditional processes or tools due to limitations of cost or the absence of suitable mechanisms.
Along with the launch of Visual Studio 2017, Microsoft has released many fresh and exciting features for mobile developers to develop cross-platform mobile apps using Xamarin. Visual Studio 2017 will help you to build better native cross-platform apps in less time as compared to Visual Studio 2015.
Xamarin Forms allows developers to build cross-platform mobile app using the common UI pages, layouts, views, controls, and design patterns. At runtime, each Xamarin Forms UI element will be mapped to its native equivalent element in each platform, so that truly native UI can be build and rendered.
Xamarin Forms is a part of Xamarin family to build truly native apps for iOS, Android & Windows from a single and shared code base using C#. Xamarin.Forms offers the UI controls/views which you can use to develop UI. These UI controls/view at run-time are converted to platform-specific UI controls.
In this article you will learn how to debug any web application that is hosted on IIS by attaching worker process of that application to Visual Studio. Also, you will learn about various authentication mode in IIS.
By default, each application pool runs with a single worker process (W3Wp.exe). When an application pool runs with multiple worker process, it is called web garden.
When a web application is hosted on multiple web servers and access based on the load on servers, it is called Web Farm.
IIS has two main layers - Kernel Mode and User Mode. The Kernel Mode contains the HTTP.SYS and User Mode contains WAS and W3 service. The subsection of both are shown in fig.
An Internet Information Services (IIS) application pool is a set of URLs that is routed to one or more worker processes. Application pools responsible for to isolate one or more applications into their own process. For example you have two different website like website-A and website-B and want to deploy on same server, then application pool isolate your website means website-A run on one
IIS stands for Internet Information Service. IIS is a web server developed by Microsoft and used to host the Web application. It has its own ASP.NET Process Engine to handle the request. So, when a request comes from client to server, IIS takes that request and process it and send response back to clients.
This pattern is used to create and perform new operations onto a set of objects without changing the object structure or classes. This pattern enables loose coupling and addition of new operations without changing the existing structure.
This pattern is used to define the basic steps of an algorithm and allow the implementation of the individual steps to be changed. This pattern looks similar to the strategy design pattern. The main difference is the ability to change the parts of an algorithm rather than replacing an entire algorithm.
This pattern involves the removal of an algorithm from its host class and putting it in a separate class. As you know, there may be multiple strategies which are applicable for a given problem.
This pattern is used to alter the behavior of an object when it’s internal state changes. In this pattern, an object is created which represent various states and a context object whose behavior varies as its state object changes.
This pattern is allows a single object, known as the subject, to publish changes to its state and other observer objects that depend upon the subject are automatically notified of any changes to the subject's state.
