Wondering why node.js is gaining popularity? When to use node.js? This page has all the details you need about Node.js framework and related best practices in the community. Node.js unravels concurrency by supplanting the Java platform’s standard, multithreaded methodology with single-threaded, event driven I/O. In this article, we discuss Node.js and clarify why its event driven concurrency has started so much intrigue, even among hardcore Java developers. We then demonstrate you some Node.js best practices to influence Node’s Express framework, Mongolian DeadBeef, and MongoDB to assemble a concurrent, adaptable, and persistent web application. Some Historical Background In last couple of years, JavaScript has risen as a “dark knight,” type of legend for web application development. This fact surprises many web app developers, who used to dismiss JavaScript as a "toy language". While there are more famous languages, JavaScript’s special status as the standard, browser-neutral scripting language has helped it stay in the mainstream. For client-side web app development, it is arguably the most used language across the globe. JavaScript additionally has a spot in server-side scripting, and that aspect is developing. While there have been endeavors at server-side JavaScript previously, none has apparently caught as much energy as Node.js, or Node. What Is Node.js? Node.js is an open source, cross-platform runtime environment for server-side and networking applications. Node.js applications are developed in JavaScript, and those apps can run inside of the Node.js runtime on OS X, Microsoft Windows, Linux, FreeBSD, NonStop and IBM. Purpose Intended to help developers in building adaptable system programs, Node is a server-side programming environment that has basically reevaluated JavaScript for an entire new era of developers. For some Java developers, Node’s greatest advantage is its crisp way to deal with programming concurrency. While the Java platform keeps on developing in its way to deal with concurrency (with greatly anticipated improvements in Java 7 and Java 8), the important fact is that it fulfills a special need, and it does so in such a tremendous way that a lot of JavaScript developers is embracing it. Like client-side scripting with JavaScript, server-side scripting in the Node environment is so great in light of the fact that it just works, and it’s working in a region where numerous Java developers are as of now tested. In this article, we will begin with a structural outline of what makes Node extraordinary, and after that we’ll demonstrate industry standards to swiftly build an adaptable web application that influences MongoDB for information industriousness. As a reader, you can observe that, how fun Node is, and how rapidly one can use it to build a working web application. Why Node.js is So Popular? There are many reasons all tech giants are loving node.js. More and more applications are being developed using Node.js and its getting adopted by industry really fast. Here are some obviously visible reasons whey Node.js is so popular. Easy To Learn Node.js is a easy to learn environment. Its a thin stack primarily based on JavaScript and developers are mainly focused on learning JavaScript programming. Many existing JavaScript developers are easily able to learn it on their own. At the same time there is plenty of good node.js books available for beginners at node. Those who do not know JavaScript can also easily learn from JavaScript tutorials freely available on web. Beginner at JavaScript can refer good javascript books. Node.js Has Cross Platform Support Node.js is available on all popular operating systems including Linux, Windows and Mac OSX. An easy installer is available for all environments. Node.js Scalability and High Performance The main reason for quick adoption of Node.js is its performance on production systems. Many high traffic production systems are deployed and being served with Node.

js. Companies like Paypal and Walmart have reported their Node.js apps are performing really well in high volume traffic and easily scaled up. Node’s Event Driven Concurrency Node is a versatile, event driven I/O environment based on top of Google’s V8 JavaScript engine. Google V8 really incorporates JavaScript into local machine code before execution, bringing about amazingly quick runtime execution — something not commonly associated with JavaScript. Thusly, Node empowers you to quickly build network applications that are extremely quick and very concurrent. Event driven I/O may sound remote to a Java developer’s ears, yet it isn’t too new. Instead of the multithreaded programming model we’re used to on the Java platform, Node’s way to deal with concurrency is single-threaded, with the extra kick of an event loop. This Node build empowers non-blocking or asynchronous I/O. In Node, invocations that commonly would block, for example, waiting for database query results, don’t. Instead of hold up for costly I/O exercises to finish, a Node application issues a callback. At the point when an asset is given back, the joined callback is summoned non-concurrently. Concurrency just works in Node programs. If I needed to run the past scenario on the Java platform, I would have my decision of complex and prolonged methodologies — from conventional threads to fresher libraries in Java NIO and even the enhanced and redesigned java.util.concurrent package. While Java concurrency is capable, it can be hard to comprehend — which translates to code. Node’s callback system, by examination, is incorporated with the language; you don’t need special constructs like synchronized to make it work. Node’s concurrency model is amazingly simple, and that makes it accessible to a wider audience of developers Better Talent Availability and Retention Though you can find thousands of Java developers, however the availability of Node.js developers is not poor either. The Node.js developers are plenty on best freelance websites. Better Productivity Since Node.js is developed using JavaScript on both server and client side. The development is much faster and consistent. One JavaScript developer can understand and develop the application end to end without worrying about interaction complexity between layers of client and server side. Java based application may still require a JavaScript developer to device a rich user interface and a in depth communication may be required between JavaScript programmers and java developers. Active Community Node.js community is very active and quick help is always available on popular forums and discussion boards. Stackoverflow has 80K+ questions that are asked by people and very few are unanswered. Plenty Of Useful Tools For Developers Since Node.js is mainly JavaScript its easy to find tools for it. Many IDEs and developer tools are already available for JavaScript that can be used for Node.js. JavaScript is understood by the browser therefore there are many cloud based JavaScript IDE available for it to develop and debug Node.js online. Easy Node.js Hosting Though you can go for a dedicated hosting servers options and easily setup your own Node.js infrastructure. However there are many easy to setup hosting providers available for Node.js environment. These providers already have a basic setup for Node.js applications and helps you quickly get to your business. Here is a list of hosting providers that support Node.js Why Pick Node.js? The Java platform’s approach to concurrency served to set up its leading part in big enterprise development, and that isn’t likely to change. Frameworks like Netty (and Gretty) and center libraries like NIO, and also java.util.concurrent, have settled on the JVM a top decision for concurrency. What’s unique about Node is that it is a current development environment particularly intended to determine the difficulties of simultaneous programming. Node’s event driven programming

ideal model implies that you needn’t bother with extra libraries to make concurrency work, and that is uplifting news for developers peering toward multicore equipment. Where Can We Use Node.js? There are many web application scenario where node.js works much better than a traditional server side programming language like java or PHP. The main advantage of Node.js is use of real time two way connection between client and server. This make node.js a popular choice for rich client applications that has many small components that can be interacting with server in parallel. If you want to create a dashboard application with multiple types of data formats and components on a page. Node.js may be a good choice. Some practical applications where node.js may go really well are listed below. Displaying a Stock market dashboard Website monitoring dashboard for dev ops Live network stats on a web page Production system monitoring dashboard Chat application Applications that run on JSON based NOSQL databases. Applications that require interaction with Mobile device and native apps. Applications that require interaction with Internet of things (IOT) based devices Where Should We NOT Use Node.js? Just like any other option, Node.js is not a one size fits all solution for all your problems. Below are types of system where node.js may not be a good choice. Applications that involve heavy computations and require more CPU processing Applications that interact with relational database like Oracle, MySQL or Postgress Conclusion Node’s JavaScript linguistic structure likewise spares you keystrokes, for sure. With only a little code, you can manufacture a quick, versatile web application that is equipped for taking care of bunch simultaneous associations. You can do that on the Java platform; however you’ll require more lines of code and a group of extra libraries and develops. What’s more, in case you’re agonized over exploring another programming environment, don’t be: Node is anything but difficult to get on the off chance that you know some JavaScript, which I bet that you do. I am an app developer, working in a smartphone applications developer company called Cygnis Media. My main interest is in mobile phone app development, but I also love to read & write about other technologies too. I like to share my knowledge, expertise, and experiences with different tech-communities on the web via social media platforms and tech blogs.

High-volume, low-latency Java applications

Concurrency and Multithreading

Thread Pooling: Use thread pools (Executors in Java) to manage threads efficiently, avoiding the overhead of creating and destroying threads for each task.

Non-blocking I/O (NIO): Leverage Java NIO for handling large numbers of connections or requests without blocking threads.

Asynchronous Programming: Use CompletableFuture, or other async frameworks (like Project Reactor or Akka) to avoid blocking and enhance throughput.

ForkJoinPool: For divide-and-conquer parallelism, utilize the ForkJoinPool to break tasks into smaller sub-tasks.

2. Efficient Data Structures and Algorithms

Low-latency Collections: Use specialized collections like ConcurrentHashMap for thread-safe, highly scalable access to data. Consider using high-performance libraries like Agrona or JCTools for non-blocking data structures.

Minimize Locking: Avoid blocking locks and shared states whenever possible. Instead, use lock-free and wait-free algorithms (atomic operations via java.util.concurrent.atomic) to avoid contention.

Immutable Objects: Use immutability to reduce synchronization needs and ensure safe access across multiple threads without locks.

Garbage Collection Optimization

Garbage Collection (GC) Tuning: Configure garbage collectors to minimize GC pauses. Some low-latency collectors in the JVM include:

ZGC (Z Garbage Collector): Offers very low pause times even with large heap sizes.

Shenandoah GC: Reduces garbage collection pauses by performing more work concurrently.

G1 GC (Garbage First): Can be tuned to meet specific pause-time goals.

Object Pooling: Reuse objects to reduce the frequency of memory allocation and GC pressure.

Avoid Excessive Object Creation: Prefer primitive types and arrays over objects, especially in hot paths.

4. Network I/O Optimization

Zero-Copy I/O: Utilize memory-mapped files or Java NIO’s DirectByteBuffer for efficient data transfer without the overhead of copying data between buffers.

Use Asynchronous Networking: Java NIO combined with AsynchronousSocketChannel can handle large numbers of I/O operations concurrently without blocking.

Minimize Serialization Overhead: Use efficient serialization formats like Protocol Buffers, FlatBuffers, or MessagePack instead of Java's built-in serialization, which can be slow and memory-intensive.

5. Low-Latency Messaging Systems

Use of Messaging Systems: Low-latency messaging frameworks such as Disruptor (by LMAX) can help bypass traditional locking mechanisms by using a ring buffer architecture, reducing latency in message passing.

Off-Heap Memory: Libraries like Chronicle Queue and Chronicle Map allow storing data off-heap, reducing the load on the garbage collector and improving performance in messaging applications.

6. Database Optimization

NoSQL Databases: For high throughput, consider NoSQL solutions like Cassandra, MongoDB, or Redis for their ability to scale horizontally and handle large datasets.

In-Memory Data Stores: Use in-memory databases (like Redis or Memcached) to avoid disk I/O latency.

Sharding and Partitioning: Distribute data across multiple databases or nodes to ensure scalability and reduce the load on any single system.

7. Minimizing Latency in Critical Paths

Microservices Architecture: Use microservices to break down complex applications into smaller, more manageable components, reducing latency by allowing independent scaling.

Event-Driven Architecture: Use event-driven designs with systems like Kafka or RabbitMQ to decouple components and reduce synchronous calls that can introduce latency.

8. JVM and OS Tuning

CPU Affinity and Pinning: Bind critical threads to specific CPUs to ensure that the most important tasks are not preempted or interrupted by the OS scheduler.

Tuning JVM Parameters: Optimize JVM flags like heap size (-Xms, -Xmx), garbage collector options, and direct memory settings (-XX:MaxDirectMemorySize) based on the workload.

Reduce Context Switching: Avoid excessive thread switching by using fewer, dedicated threads for critical tasks and batch processing.

9. Profiling and Performance Monitoring

Profiling Tools: Use profilers such as VisualVM, YourKit, or Java Flight Recorder (JFR) to identify bottlenecks in code, GC performance, or I/O operations.

Metrics and Monitoring: Implement real-time monitoring (using tools like Prometheus, Grafana, or ELK Stack) to track latency, throughput, and resource utilization. Continuously fine-tune the system based on observed behavior.

10. Batching and Caching

Batch Processing: Process data in batches where possible to reduce the overhead of handling multiple individual requests.

Caching: Use local caches like Caffeine or distributed caches like Redis to store frequently accessed data, reducing the need for repeated data fetching or computation.

sudo lsof -i :<port_number>

High-volume, low-latency Java applicationsThread Pooling: Use thread pools (Executors in Java) to manage threads efficiently,

Asynchronous Programming: Use CompletableFuture, or other async frameworks (

Non-blocking I/O (NIO): Leverage Java NIO for handling large numbers of connections

Profiling Tools: Use profilers such as VisualVM, YourKit, or Java Flight Recorder (JFR)

Microservices Architecture: Use microservices to break down complex applications into smaller.

///

Class Loading

Preload Classes: You can load key classes in advance to avoid delays caused by lazy class loading during the first few requests.

Heap Sizing: Ensure the heap size (-Xms and -Xmx) is set correctly to avoid resizing the heap during runtime,

Database Connection Pool: Pre-initialize a database connection pool (e.g., HikariCP, Apache DBCP) so that connections are readily available

SQL Query Caching: If your database or ORM (like Hibernate) uses query caches, run key queries to ensure that the cache is warmed up and execution plans are cached in the database.

Class Data Sharing (CDS): Java provides a Class Data Sharing (CDS) feature that allows the JVM to share class metadata between JVM instances to speed up class loading.

Preloading with Frameworks (Spring Boot Example)

In frameworks like Spring Boot, you can use @PostConstruct to execute code after the application has been initialized, which is a great place to add preloading logic.

Using Map for Faster Lookups

If you want to be able to quickly look up students by their ID, for example, you can use a Map structure (HashMap or ConcurrentHashMap) that allows O(1) lookup.

Example of an In-Memory Data Map Using HashMap

to create a thread-safe and concurrent version of a HashMap, you can use the ConcurrentHashMap class in Java.

ConcurrentHashMap is a great choice when you need a thread-safe map that supports high concurrency with minimal contention.

Inserting a null Key or Value

If you attempt to insert a null key or value in a ConcurrentHashMap, a NullPointerException will be thrown.

///

ConcurrentHashMap<Student, Student>: In this example, ConcurrentHashMap is used with Student objects as both keys and values. To use Student as a key, the hashCode() and equals() methods are overridden to ensure correct key lookups.

Thread Safety: ConcurrentHashMap allows multiple threads to access the map concurrently, without needing explicit synchronization, ensuring thread-safe read and write operations.

///

Race conditions occur when multiple threads concurrently modify a shared variable without proper synchronization.

To prevent race conditions, use synchronized blocks or atomic variables like AtomicInteger for thread-safe operations.

Using synchronized Block Without static

In this solution, we create an instance variable I, and use a synchronized block to ensure thread safety. Each thread will still share the same IncrementWithSync object, so the synchronization applies to the object instance.

How the Garbage Collector Works?

Java uses reachability to determine when an object is no longer needed. If an object is no longer referenced (reachable) from any live thread, it becomes eligible for garbage collection.

Root Sources of Object References (GC Roots):

Local variables on the stack.

Active threads.

Static fields.

JNI (Java Native Interface) references.

When objects are used as keys in hash-based collections (e.g., HashMap, HashSet), the hashCode() method is used to determine the object's bucket, and equals() is used to check whether the two objects are logically equivalent.

Why is Java the Ideal Choice for Backend Development?

Steering Backend Development with Java

Backend programming is also known as server-side development, which refers to the behind-the-scenes logic that boosts web applications. This back-end development includes everything that exists in the server, and they include everything from data storage and modeling to security concerns. The backend developers play an important role in ensuring that the application works smoothly, focusing on websites, back-end logic, architecture, servers, and Application Program Interfaces (APIs). Moreover, it includes functionality, which needs to be accessed and navigated by digital means. In this blog, we will answer the question of why developers prefer Java for backend processes and we will drive through the advantages of using Java backend development. So, without any further delay, let us jump into this blog!

Exploring how does Java increases the Backend Development process

Backend programming languages like Java, C#, and PHP are very adaptable to gain all certain information from the stored database when it is processed through an application. The backend receives input from the front-end and generates and sends responses to the clients. Enterprise applications need to be more difficult and secure to make sure that the data are confidential. It is the perfect choice for managing backend processes as it offers a lot of advantages and benefits. Java is the most popular and universally used programming language used for creating innovative and powerful web applications. The Java code is compiled into bytecode, and then it will be compiled by the Java compiler. JVM acts as an interpreter between the underlying hardware and the programming language, and it also provides a runtime environment for the applications to run on different OS.

Java-based applications can eventually run on any platform like iOS, Android, etc. Nowadays, most developers prefer Swift for iOS and Kotlin for Android, but a major principle is that these languages are nothing but only an advanced Java version with some similarities at the core. It is impossible to invade a Java-based application as it has a lot of in-built security features. Furthermore, Java has less ambiguous syntax terminology and enables beginners to initiate Java with basic principles. Additionally, Java is a stable and reliable programming language for developing backend applications, which makes it a popular choice for developing enterprise applications.

Java is an extensible, modular, accessible programming language that supports principles like polymorphism, encapsulation, overloading, and data abstraction. Java’s multithreading ability makes it a highly-demandable programming language in the industry. Multithreading permits developers to maximize the CPU’s usage, and it also shares memory space and boosts applications efficiency and performance. The multithreading ability prevents Java applications from performing slow and unresponsive tasks when a lot of work is needed. Moreover, it is very useful in the backend development as it effectively handles multiple tasks simultaneously. It is great for backend development, and it is very much vital in multithreading, using effective resources, boosting application performance, and it also enables developers to create ascendable and innovative backend systems to handle complex requests and data.

Closing the Blog Backend Development with Java

From this blog, we have learned about the advantages and key features of using Java in backend development. It allows developers to build a strong backend for handling all the complex data. Also, Java has an automatic garbage collector that helps developers to avoid problems like segmentation faults and memory leaks.

This library implements high-performance MPI 3.1 and 4.0 on numerous fabrics. This lets you quickly optimise application performance without changing operating systems or applications, even if you switch interconnects.

Thread safety allows hybrid multithreaded MPI applications to be traced for optimal performance on Intel multicore and manycore platforms.

The process manager mpiexec.hydra enhances start scalability and launches concurrent processes.

It natively supports SSH, RSH, PBS, Slurm, and SGE.

Google Cloud Platform, Microsoft Azure, and Amazon Web Services integration

Performance and Tuning Tools

Two new enhancements optimise app performance.

Independence interconnect

The library offers an accelerated, universal, multibaric layer for fast OFI interconnects with the following configurations:

TCP sockets

Community memory

Ethernet and InfiniBand use RDMA.

Dynamically creating the connection only when needed reduces memory footprint. It automatically chooses the fastest way of transportation.

Knowing MPI code will operate on any network you provide at runtime, write it without attention to fabric.

Using two-phase communication buffer-enlargement, just enough memory should be allocated.

Compatibility of App Binary Interface

Applications use application binary interfaces (ABIs) to communicate between software components. It controls function invocation, data type size, layout, and alignment. ABI-compatible apps use the same runtime naming conventions.

The MPI Intel Library provides ABI compatibility with MPI-1.x and MPI-2.x programs. You can utilise the library's runtimes without recompiling to get its speed improvements, even if you're not ready for 3.1 and 4.0.

Intel MPI Benchmarks measure MPI performance for point-to-point and global communication across message sizes. Run each supported benchmark or give a single executable file via the command line to get subset results.

The benchmark data fully describes:

Throughput, network latency, and node performance of cluster systems

Efficiency of MPI implementation

Adjust the library's comprehensive default settings or leave them as is for optimal performance. If you want to tweak cluster or application settings, use mpitune. Continue tweaking the parameters until you obtain the best results.

MPI Intel Library: Windows OS Developer Guide

MPI Tuning: Intel MPI Library supports Autotuner.

Autotuner

Autotuning might improve MPI collective operation-heavy applications. Simple to use, Autotuner has low overhead.

Autotuner utility tunes MPI collective operation algorithms I_MPI_ADJUST_ family. The autotuner limits tuning to the cluster setup (fabric, ranks, node rankings). Turning on the autotuner while an application is running improves performance. Create a new tuning file with MPI collective operations appropriate to the application and supply it to the I_MPI_TUNING_BIN variable.
