Jakarta EE, formerly Java Platform, Enterprise Edition and Java 2 Platform, Enterprise Edition (J2EE), is a set of specifications, extending Java SE with specifications for enterprise features such as distributed computing and web services. Jakarta EE applications are run on reference runtimes, which can be microservices or application servers, which handle transactions, security, scalability, concurrency and management of the components they are deploying.
An application server is a server that hosts applications or software that delivers a business application through a communication protocol. For a typical web application, the application server sits behind the web servers.
A web container is the component of a web server that interacts with Jakarta Servlets. A web container is responsible for managing the lifecycle of servlets, mapping a URL to a particular servlet and ensuring that the URL requester has the correct access-rights. A web container handles requests to servlets, Jakarta Server Pages (JSP) files, and other types of files that include server-side code. The Web container creates servlet instances, loads and unloads servlets, creates and manages request and response objects, and performs other servlet-management tasks. A web container implements the web component contract of the Jakarta EE architecture. This architecture specifies a runtime environment for additional web components, including security, concurrency, lifecycle management, transaction, deployment, and other services.
Apache Tomcat is a free and open-source implementation of the Jakarta Servlet, Jakarta Expression Language, and WebSocket technologies. It provides a "pure Java" HTTP web server environment in which Java code can also run. Thus it is a Java web application server, although not a full JEE application server.
In software engineering, service-oriented architecture (SOA) is an architectural style that focuses on discrete services instead of a monolithic design. By consequence, it is also applied in the field of software design where services are provided to the other components by application components, through a communication protocol over a network. A service is a discrete unit of functionality that can be accessed remotely and acted upon and updated independently, such as retrieving a credit card statement online. SOA is also intended to be independent of vendors, products and technologies.
WebSphere Application Server (WAS) is a software product that performs the role of a web application server. More specifically, it is a software framework and middleware that hosts Java-based web applications. It is the flagship product within IBM's WebSphere software suite. It was initially created by Donald F. Ferguson, who later became CTO of Software for Dell. The first version was launched in 1998. This project was an offshoot from IBM HTTP Server team starting with the Domino Go web server.
Hessian is a binary Web service protocol that makes Web services usable without requiring a large framework, and without learning a new set of protocols. Because it is a binary protocol, it is well-suited to sending binary data without any need to extend the protocol with attachments.
The acronyms BAPP and BAMP refer to a set of open-source software programs commonly used together to run dynamic websites or servers. This set is a solution stack, and an open source web platform.
Aptana, Inc. is a company that makes web application development tools for use with a variety of programming languages. Aptana's main products include Aptana Studio, Aptana Cloud and Aptana Jaxer.
Nginx is a web server that can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache. The software was created by Russian developer Igor Sysoev and publicly released in 2004. Nginx is free and open-source software, released under the terms of the 2-clause BSD license. A large fraction of web servers use Nginx, often as a load balancer.
OpenKM is a document management system that provides a web interface for managing nonspecific files. It has a Free/Libre Community Edition, and a proprietary Enterprise Edition. OpenKM includes a content repository, Lucene indexing, and jBPM workflow. The OpenKM system was developed using open technology.
Platform as a service (PaaS) or application platform as a service (aPaaS) or platform-based service is a category of cloud computing services that allows customers to provision, instantiate, run, and manage a modular bundle comprising a computing platform and one or more applications, without the complexity of building and maintaining the infrastructure typically associated with developing and launching the application(s), and to allow developers to create, develop, and package such software bundles.
WaveMaker is an enterprise-grade Java low-code development platform for building software applications and platforms. WaveMaker Inc. is headquartered in Mountain View, California. For enterprises, WaveMaker is a low-code platform that aims to accelerate their app development and IT modernization efforts. For ISVs, it is a consumable low-code component that can sit inside their product and offer customizations.
Resin is a web server and Java application server developed by Caucho Technology. There are two versions available: Resin (GPL), which is free for production use, and Resin Pro, designed for enterprise and production environments with a licensing fee. Resin supports the Java EE standard and features a mod_php/PHP-like engine known as Quercus.
Apache Attic is a project of Apache Software Foundation to provide processes to make it clear when an Apache project has reached its end-of-life. The Attic project was created in November 2008. Also the retired projects can be retained.
Jelastic is a cloud platform software vendor that provides multi-cloud Platform as a Service-based on container technology for hosting service providers, ISVs, telecommunication companies, enterprises and developers. The platform is available as public cloud in over 70 data centers, as well as virtual and on-premises servers. Jelastic provides support of Java, PHP, Ruby, Node.js, Python, Go environments, custom Docker containers and Kubernetes clusters.
In software engineering, a microservice architecture is a variant of the service-oriented architecture structural style. It is an architectural pattern that arranges an application as a collection of loosely coupled, fine-grained services, communicating through lightweight protocols. One of its goals is that teams can develop and deploy their services independently of others. This is achieved by the reduction of several dependencies in the code base, allowing developers to evolve their services with limited restrictions from users, and for additional complexity to be hidden from users. As a consequence, organizations are able to develop software with fast growth and size, as well as use off-the-shelf services more easily. Communication requirements are reduced. These benefits come at a cost to maintaining the decoupling. Interfaces need to be designed carefully and treated as a public API. One technique that is used is having multiple interfaces on the same service, or multiple versions of the same service, so as to not disrupt existing users of the code.
