Over time, enterprise-grade Java applications can become giant hulking beasts of intertwined code, bloated with third-party libraries, and vulnerable to total collapse when a single part fails. It doesn't have to be that way!
This example-rich tutorial shows how to design and manage large-scale Java applications as a collection of microservices.

The main aim of service-oriented architecture is to allow users to mix large chunks of functionalities into one in order to build an application and services by combining services. This architectural design of node backend application is considered a best practice in industrial labels.
Spring is widely used for creating scalable applications. For web applications Spring provides
Spring MVC which is a widely used module of spring that is used to create scalable web applications. But the main disadvantage of spring projects is that configuration is really time-consuming and can be a bit overwhelming for the new developers. Making the application production-ready takes some time if you are new to the spring.

In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

Enterprise Java Microservices : creating and managing large-scale Java applications
1. Creating RESTFul endpoints
with JAX-RS for a simple
microservice.
By Ken Finnigan
Save 42% off Enterprise Java Microservices
with code slfinnigan at manning.com
2. A simple microservice.
Let’s pretend that we’re developing a simple application and that the
application will utilize JAX-RS for the RESTFul microservice, with a UI
built with ReactJS.
The application includes a UI as a way to utilize the microservice in an
easier manner. Without a UI it would require issuing curl commands
to interact with it, and UIs are nicer to look at than commands in a
terminal!
So what are we developing? A simple application for managing
addresses.
4. Application Use Cases.
We’re focusing on address management, so we don’t need to cover a
large range of use cases. Our address microservice only needs to focus
on the CRUD operations that a data object requires to create, read,
update, and delete instances of.
The UI will call the CRUD operations on the microservice for
maintaining addresses. The microservice RESTFul endpoints could be
called from any client, but we will show them operating with our UI.
6. Architecture of the Application.
Let’s take a moment and ignore microservices – the architecture for our
application would probably look something like:
7. Architecture of the Application.
At the Presentation Layer we use ReactJS for the UI. The API Layer
contains the RESTFul endpoints utilizing JAX-RS for employee and
address. CDI services for employee and address represent our Business
Layer, which is called by the API Layer. Finally there are JPA entities of
employee and address in our Data Layer that interact with the physical
database. The Business Layer is responsible for interacting with the
Data Layer to persist record updates.
Whether the API Layer and Business Layer would be separate or not
depends on preference, as they could be handled within a single layer.
Typically all these layers would be packaged within a single WAR for
deployment to an application server.
8. Architecture of the Application.
How does the architecture change when we shift to constructing a
microservice?
Our server side layers are encompassed in a single Microservice. Our UI
then sits in its own WAR, to package and deploy the UI to a separate
runtime.
9. As we’ve split our UI and services into separate runtimes, we need to
add support for cross origin resource sharing (CORS). If we don’t, the
browser will prevent the UI from making an HTTP request to the
microservice. To do this our microservice needs a filter:
10. Creating RESTFul endpoints with JAX-RS.
To keep the microservice simple we will focus on the RESTFul endpoint
--the API Layer-- and ignore the development of the additional layers.
Any Enterprise Java developer would then be able to take the
microservice and extend it to utilize CDI and JPA if they wanted.
11. Developing the AddressController.
Our AddressController will focus on making the CRUD style
operations for address data available from RESTFul endpoints. It
specifies that the RESTFul @Path for the controller is /address. We
then define a counter as a unique identifier, and a Map to store the
addresses in memory. Last, we populate an internal Map called
addresses with some initial data during construction of the instance.
As we’re storing data for addresses in our controller, we need to make
the class a singleton within JAX-RS. By default, all JAX-RS resource
instances are only active on a per-request basis. If we don’t change
that, then every request will see the same initial data state every time,
and the UI would never show different data no matter how many new
addresses were added or updated.
12. Developing the AddressController.
We need to define a JAX-RS
application that can indicate
to the implementation which
RESTFul endpoints we want to
be singletons:
13. Viewing all addresses.
Now it’s time to develop the RESTFul endpoints we need for CRUD of
our addresses.
14. Deleting an address.
Once we have an address, we need the ability to delete an old one that
isn’t used. For that we need to add a RESTFul endpoint for deleting an
address from the database.
15. Adding an address.
Here we have a RESTFul
endpoint to add a new
address into our database
and provide it with a
unique identifier.
16. Running the microservice.
Although we’ve indicated that our RESTFul endpoint is an Address
microservice, there’s actually nothing in the code we’ve developed that
prevents it from being built as a WAR and deployed to an application
server. As we’re only dealing with a UI communicating with a single
microservice, there isn’t any difference between that and existing
Enterprise Java development with WARs. The upside to the similarity is
that it makes it easier to migrate existing Enterprise Java code into a
Microservice if no code changes are required for a microservice
producer.
To give more of a microservice feel for our example, we will package it
as an uber jar with WildFly Swarm.
17. Running the microservice.
WildFly Swarm offers an alternative approach to packaging your
applications utilizing WildFly instead of a full Java EE Application Server.
It allows us to choose the parts we need from WildFly and package
them into an uber jar that can be run from the command line.
To do that we need to add the following plugin to our pom.xml:
Latest version of WildFly Swarm.
Specify a port offset of 1 so
our microservice will start on
port 8081.
18. Running the microservice.
That’s all we need to do to provide a way to run the microservice from
the directory, as well as package it as an uber jar.
So how and what do we run?
There are two pieces that need to be run, one for the UI and one for
the microservice. If you wanted to execute some tests against the
RESTFul endpoints directly, without using the UI, then you only need to
start the microservice.
Let’s see what we need to do to start our microservice:
19. Running the microservice.
Open a terminal, or command window, and navigate to the /chapter2/jaxrs
directory of the book example code (https://github.com/kenfinnigan/ejm-
samples). From that directory run:
This will start the microservice containing our RESTFul endpoints for
address crud. Once the log shows that the microservice is deployed you
can go to a browser and open it to:
Your browser will load the initial address
data and display it in JSON format. Now
we know the microservice is running,
let’s run the UI.
20. Running the microservice.
Now let’s start the UI.
Open a terminal and navigate to the /chapter2/ui directory of the book
example code. From that directory run:
This will start a web server with the UI code only. Once the log shows
that it’s deployed you can go to a browser and open it to:
Your browser will load the UI containing some sample address data.
21. Voila! That’s all for now.
