RESTful web services are loosely coupled, lightweight web services that are particularly well suited for creating APIs for clients spread out across the internet. And to build Web services that are lightweight, maintainable, and scalable in nature. A service which is built on the REST architecture is called a RESTful service. The underlying protocol for REST is HTTP, which is the basic web protocol. REST stands for Representational State Transfer.

We do have different types of frameworks to Develop Rest API, the following frameworks are widely used for API implementation.

  1. Apache CXF

  2. Jersey, the reference implementation from Sun (now Oracle)

  3. RESTeasy, JBoss's implementation

Building a Binary Classification Model in Azure ML

"First impressions are "Finally, a practicing educator" Course delivery is smooth and spot on. Right before you lose hope a gem like this pops up - thanks."  - Don Councill

Welcome to Building a Binary Classification Model in Azure ML.

Microsoft’s goal of democratizing machine learning is taking shape.

Taking predictive analytics to public cloud seems like the next logical step towards large-scale consumerization of Machine Learning. Azure ML does just that, while making it significantly easier for the developers to build high probability machine learning models without a PhD in statistics.

In this course, we are going to build one of the simplest and most common models, the binary classification model.

The goal of binary classification is to categorize data points into one of two buckets: 0 or 1, true or false and to survive or not to survive.

Many decisions in life are binary, answered either Yes or No. Many business problems also have binary answers. For example: “Is this transaction fraudulent?”, “Is this customer going to buy that product?”, or “Is this user going to churn?” In machine learning, this is called a binary classification problem.

We will use binary classification to predict the probability of someone surviving if they had been aboard the Titanic.

We are going to create an end to end workflow. We will download the data set, clean it, model it, evaluate it then publish our results so others can use it.

Upon completing the course you’ll know how to create a model that accurately predicts the survivability of an individual based on attributes in the data set.

You’ll gain insight into the vernacular used in machine learning. 

For example, in the last sentence I used the world ‘attribute.’  An attribute in machine learning is no different than a column in a data set.

Various attributes affect the outcome of the prediction. For example, my chance of survival was 21.07% if I would have been in first class. If I would have been in second class my changes dropped to 2.16%. Either way, I wouldn't have made it. 

Thanks for your interest in Building a Binary Classification Model in Azure ML..  We will see you in the course!!!

JAX-RS the Java API for RESTful Web Services is a Java programming language API specification that provides support in creating web services according to the Representational State Transfer (REST) architectural pattern. JAX-RS uses annotations, introduced in Java SE 5, to simplify the development and deployment of web service clients and endpoints.

From version 1.1 on, JAX-RS is an official part of Java EE 6. A notable feature of being an official part of Java EE is that no configuration is necessary to start using JAX-RS. For non-Java EE 6 environments a small entry in the web.xml deployment descriptor is required.

This course will guide you through the steps in creating powerful RESTful web services using the Java official API.

Turbocharge your production web services!

Are your web services suffering from performance issues?   Every web programmer has experienced cases where web services or applications that ran perfectly in test and QA under light load failed (often spectacularly) when put under the load of a production deployment.

Performance has a strong relationship with cost.  If you could either run double the load on the same hardware, or run the same load on half the amount of hardware, the cost impact can be tremendous for your project.

Wouldn’t it be nice if you had a bag of tricks that you could use to perfect your web service performance characteristics under load before you deployed to production, way back in the design and development phases where the cost was lowest?  Maybe you inherited a legacy system that’s suffering from performance problems.  But where do you start?   Wouldn’t you like to be able to identify the problem areas quickly and be ready with some time-tested approaches to fix them?

That’s what this course is about: Practical, real world techniques that are easy to understand and use, that let you get maximum performance from your web services.  You'll discover new ways of thinking about performance that you will use on every project, saving you time and money.

The Golden Rules of Performance

In this course you will learn my mental framework for creating solutions to performance-robbing problems that you can use in the design, development and production support phases of your services.  The framework is built on a foundation that I call my Golden Rules of Performance, an easy to remember and easy to apply approach that will help you find and fix trouble areas in your code and architecture.

The course also includes a Golden Rules Cheat Sheet for you to use after the course giving you questions to ask, typical problem areas, and techniques to apply for a variety of scenarios.  In one example you'll see how something as simple as logging can be dramatically improved by applying the Golden Rules.

You'll gain a clear understanding of how techniques like caching, queues and messaging, horizontal scaling, and other performance-boosting mechanisms work together to create systems that can dramatically increase your web services' capabilities. 

The Experience

The course is divided into two parts.  The first half is the "abstract" portion, consisting of spoken lectures that lay out the Golden Rules of Performance and regular "Reality Bites" segments that draw from my own personal experiences as a developer to show the rules in action in actual real world scenarios.  There's no code involved in this part, just me talking with some occasional diagrams where it helps.

The second half is the "concrete" portion, where we start with a small web service and progressively apply the rules in various ways to improve the performance of it by 2.5 times with simple program changes so that you can see the Golden Rules in action.  You'll see an example of logging performance increased by more than 100 times!

This is not a course where you will write code!  This course is for thinking about system architecture and program design, not about using a particular language or framework.  The assignments are intended to be more of an open discussion than "right or wrong" code submissions; to get the most benefit, consider making your submissions public so everyone can participate in the discussion.

I've tried to speak somewhat slowly to make the videos easier to follow if English is not your primary language, and there are captions in all videos to help as well.  If your primary language is English, you may want to use the video controls to quicken the playback speed to something more comfortable.

The Tech Stack

This course is not about any specific tech stack!  You can use these techniques with any language or framework you are using to create modern web services or applications.

For the examples, I will be using the C# language , Web API for .NET Framework for the web service framework, some Microsoft Azure features, and Microsoft SQL Server database--  but you don't need to know anything about C#, Web API framework, Azure or SQL Server to be able to follow what is happening in the examples since the discussion will be at a higher level.  Remember, this course is for thinking about architecture and design, not writing or reviewing code.

Real World Focus

My "Real World" courses specifically target working developers solving actual problems in typical business programming scenarios.  They are uniquely designed to cover areas you don't find in other courses on similar topics, from the specific viewpoint of developers who need to translate theory into practical application to solve the kinds of problems the "overview" courses don't help with.  I assume you already know how to program and have built working commercial systems-- you won't find any "Hello, world" here!
