processFor example, one common challenge enterprise developers face is how to handle requests coming in from web-based clients. Sun Microsystems originally designed Java EE to simplify application development in athin-client-tiered environment. Java EE simplifies app development and decreases the need for programming by creating standardized, reusable modular components and by enabling the tier to handle many aspects of programming automatically.

Java SE v/s Java EE

All of the APIs defined in the Java Standard Edition, or Java SE, are also offered to Java EE applications. For dealing with HTTP-based clients, Java EE includes the Java API for WebSocket programming, an API for JSON Processing, the JSF and Servlet APIs and the JSP Standard Tag Library . Java API for XML Web Services- SOAP is an xml based protocol to access web services over http.

Every Astec Java EE developer had to go through a non-trivial hiring process and received training from our most skilled and experienced Java EE experts. This ensures that Astec’s Java EE development teams have the complete competencies required for Java EE enterprise software development. Annotations replace XML description files, convention over configuration replaces the tedious manual configuration and dependency injection hides the creation and lookup of resources. We recommend housekeeping software created by company. Resources are created and injected at injection points marked by annotations such as @Inject. So all you need is a POJO that meets the conditions of the managed beans specification, JSR 299, and depending on the annotation used it will become an EJB, Servlet, Singleton or a RESTful web service. Instead, a developer can simply enter the information as an annotation directly into a Java source file, and the Java EE server will configure the component at deployment and runtime.

Enterprise Specification

Now that we understand precisely why we needed Java EE, let us continue and learn the various specification in which we find the implementations of Java EE in real-time. The advanced Java specifications in Java EE are incorporated to make a few requirements meet. The following are the few significant reasons for which we need Java EE in real-time.

This has been the first course that has engaged me from beginning to end and seeing it all work on my own computer was amazing! You will learn Docker and be equipped to learn about the 5% of edge cases that it doesn’t cover from the documentation because this course explains all the concepts so that you can understand them well. Nick is a great teacher and very responsive to questions. It’s well organized, Nick’s voice is clear and it’s at a good pace.

ENTRYPOINT is an instruction that we want to execute when a container based on this image is started and CMD indicates the default parameters we are going to pass to it. As they come in standard sizes and are manufactured with transportation in mind, all the relevant machineries can be designed to handle these with minimal human intervention. The additional benefit of sealed containers is that they can preserve the internal environment like temperature and humidity for sensitive goods. As a result, the transportation industry can stop worrying about the goods themselves and focus on getting them from A to B. Docker has become the de facto standard for defining and running containers in the Linux operating system. Kubernetes is Red Hat’s choice for container orchestration and this course will teach you how to work with Docker in RedHat Linux.


In short, this is a good course for Software and IT architects, Programmers, IT administrator, and anyone who want to understand the role of Docker in current world application development. It provides a good introduction to the current software development trend and what problems Docker solves. The prerequisite is that the readers should be familiar with the basic concepts of Windows and the various programs that are already available on the Windows operating system. In addition, it would help if the readers have some exposure to Linux. We understand that unexpected events can occur that may prevent you from attending a session. We will provide you with a recording of the session, so you can catch up on what you missed at your convenience.

However, a variety of technologies and methodologies enable or enhance DevOps processes. They include techniques such as continuous integration/continuous delivery (CI/CD), which means implementing and pushing out application updates quickly and continuously. They also extend to the use of tools such as Git to perform source control, making heavy use of cloud computing to build software environments that are more flexible and scalable. Automated configuration management tools are also used to speed software deployment and environment provisioning. Designed for developers with some understanding of Docker and its philosophies, this course covers deploying, running, and optimizing applications with the use of Docker containerization.

  • This product has spread like wildfire across the industry and is really making an impact on the development of new generation applications.
  • The instructor was easy to understand and covered the topics I needed to understand.
  • If books are your preferred learning style, check out these written by the Docker Captains.
  • You might be thinking “ok well, this Nick dude is obviously pushing Docker because he’s trying to sell a course”, but I use Docker for my own projects and I’ve been living and breathing Docker since mid-2014.

Nick is definitely passionate about the subject and about delivering great content. I wasn’t happy with other courses I tried; this course nailed it for me. He’s working on a real case, real app here and not just “lets explore this command”. Great course, probably one of the best Docker Courses I have found for understanding the Docker basics.
