海外TECH	DEV Community	Messaging and Madness: Sending Messages with AMQP and Amazon MQ	https://dev.to/aws-builders/messaging-and-madness-sending-messages-with-amqp-and-amazon-mq-2m9b	Messaging and Madness Sending Messages with AMQP and Amazon MQOriginally posted on my personal blog Table Of ContentsIntroductionAMQPAMQP and Amazon MQSerializationConclusion Introduction How do software systems talk to each other Back end systems can scale into giant melted together Cronenberg monsters often making up different tools and languages So communicating between these services can become an untenable challenge without some shared vocabulary We can communicate in many ways but today I wanted to talk about asynchronous messaging protocols and figure out how AWS can help AMQP AMQP stands for Advanced Message Queuing Protocol I ve been working to implement it for some back end software suites I m building out to enable them to talk to each other AMQP utilizes these things called brokers to publish messages on then on the other end a receiving service subscribed to the same “channel that we posted to can pick up that message via Rabbit MQ TutorialsLet s dive a little further down the publisher service publishes a message to an exchange on a broker This exchange has routes that lead to queues or “channels where the payload is published We make sure to include the sending information with our message to be routed to the correct queue The broker cannot see the message although it might look into any metadata attached to the message from the publisher This workflow asynchronously sends messages Imagine a server version of a mail sorting machine shooting letters into the correct mail slot based on the address When referring to a publisher I mean some code that we utilize to connect and send a message AMQP is programmable so I can shape it to fit most situations In this case we need to send messages to our different software suites to trigger actions to happen Learning this took some time but it s been simple to implement There are different types of exchanges that we can use to make these services fit our needs I m going to explain what we use briefly We use a direct exchange utilizing routing keys to bind queues to exchanges Our code can use direct exchanges to distribute tasks to many different endpoints but we used these direct exchanges to make direct routes between our services Other types of exchanges can be used to broadcast messages More information can be found here For now we re going to focus on direct exchanges AMQP and Amazon MQ We touched on all that because I wanted to talk about Amazon MQ Amazon MQ is a fully managed platform for setting up message brokers Amazon MQ utilizes both RabbitMQ and Apache Active MQ for creating brokers We re sticking with Rabbit MQ for the time being Here above you can see you can easily set up a broker in just a few clicks I left most of the settings on default except for choosing “RabbitMQ for our broker engine and setting some security up for accessing our management console Once we get that we have access to the RabbitMQ dashboard Amazon MQ created and is managing Now that we have a broker set up we can play with some code Above I use the library Kombu to create some connections and send some stuff I started by setting up our environment variables Then created exchange and queue objects Finally I made our connection object and the producer object and then we sent a simple “Hello message Serialization Serialization is another blog post but I chose to use JSON to serialize the payload In the production software I use a combination of JSON and Pickle to serialize things like image data Now we can see our message published on the queue I declared in our publisher service An identical receiving service would be set up on the other side to read out messages sent to that queue Conclusion In conclusion using Amazon MQ allows us to set up managed brokers for us to send messages With AMQP as the broker engine we have a lightweight message sending workflow Thanks for reading George	2021-10-30 17:23:47

海外TECH	DEV Community	Basic concepts of Java	https://dev.to/beautyjames/basic-concepts-of-java-19k4	Basic concepts of JavaHello readers Beauty James here again with another exciting article I ve been talking about Frontend development for some time now so I ll be considering Java one of the many examples of programming languages used for Frontend development I will be discussing the following headings below •What is Java •History of Java programming language•Java Features•Java Architecture•Components of Java Programming language•What is Java Platform •Types of Java Platforms•How is Java Platform Independent •Uses and applications of JavaWhat is Java Java is a high level class based object oriented programming language designed to have just a few implementation dependencies It is a multi platform and a network centric language As other programming languages it is a platform for application development Java codes can be Compiled to byte codes to run on all platforms supporting java without recompilation Java is particularly popular for its client sever web applications with more than million developers under their belt History of Java Programming LanguageJava originally called oak was developed in the early s by James Gosling and other developers at Sun Microsystems Inc later acquired by oracle in and released in At the time the internet and the WWW were becoming more and more popular but the C and C programs used were not platform independent they had to be compiled and recompiled for different hardware and processors and required more memory So the developers sought to create a language that could run on any operating system regardless of the systems hardware or software configuration The program used for java is small and portable and could be transported over any network This new development attracted developers in no time because it also allows communication between consumer electronics making Java the most popular programming languages to this time Although James Gosling developed java in the early s he left the company after its acquisition in by Oracle Corporation to work with Amazon web services Features of Java•Object oriented Java is a fully object oriented language and possesses features such as encapsulation polymorphism inheritance abstraction class and object •Robust With features such as automatic Garbage Collection and Exception handling it helps programmers to create reliable applications which eliminates error prone codes •Simple The language is easy to learn and the syntax is clean and easily understandable •Security Java programs run in Java Runtime Environment JRE which makes little or no interaction with the Operating System making the program free from virus attacks because it can t be invaded from the outside •Multi threading Java makes use of multi threading features which makes it possible to execute multiple tasks at the same time resulting in highly interactive and responsive applications •High Performance Since Java cannot be as fast as C or C it makes use of a Java compiler which changes java codes into bytecodes so java applications can run at full speed •Independence Any machine with Java Runtime Environment can run Java programs because all java programs are compiled into bytecode which is platform Independent Java ArchitectureJava Architecture compiles and interprets a program It explains the process involved in formulating a Java program which includes converting the codes written in java into byte codes which is done by the Java Compiler The byte codes are then converted into machine code by the JVM Java Virtual Machine which is executed directly by the machine Components of JavaThere are three main components of Java language •Java Virtual Machine JVM This is a component that gives developers an environment to execute Java programs by converting byte codes into machine codes JVM first of all loads the code into memory and verifies it After that it executes the code and provides a runtime environment Hence JVM performs actions in this order loads the java codes verifies them executes them and then provides a runtime environment for the codes •Java Runtime Environment JRE JRE builds a runtime environment in which Java programs can be executed It is located on the on disk system which takes the Java code combines it with the needed libraries and starts the JVM to execute it JRE contains libraries and software that your Java programs need to run JRE is a part of JDK •Java Development Kit JDK is a software development environment used to develop Java applications and applets It contains development tools such as an interpreter loader java a compiler javac an archiver jar a documentation generator javadoc Java PlatformsA platform is a hardware or software environment in which a program runs Java has its own run time environment known as JRE Java Run time Environment and Java Virtual Machine JVM which converts Java codes to machine codes making it possible to develop and run the programs that are written in Java Programming language Java platforms includes execution engine compiler and set of libraries Types of Java PlatformsBy the late s Java grew beyond the World Wide Web and as a result Sun Microsystems created varieties of Java for different purposes also known as Java editions such as •Java platform Standard Edition Java Standard Edition is a computing platform that targets work station environments offering the Java programming language s core functionality It is used for the development and deployment of portable codes used in desktop and server environments It is also used in networking security database access Graphical User Interface GUI development and XML parsing •Java platform Enterprise Edition is a set of specifications that targets large distributed enterprises or internet environments with features such as distributed computing and web services The application runs on reference runtimes which handles transactions security scalability concurrency and the management of components to be deployed Applications of Java Platform Enterprise include e commerce accounting banking information systems •Java Platform Micro Edition This is a computing platform used for the development and deployment of portable codes for embedded and mobile devices like micro controllers sensors gateways mobile phones printers etc •Java FX JavaFX is used for creating desktop applications and Rich Internet Applications RIAs which can run on a wide variety of devices including desktop computers and web browsers Its user hardware accelerated graphics and media engines helps Java take advantage of higher performance clients and high level APIs for connecting to networked data sources How is Java Platform Independent A platform can be called independent if it can run on all available Operating Systems with respect to its development and compilation Now Java is platform independent simply because it produces a unique format called bytecode First source code is used by Java compiler and is converted in class file The class file code is in byte code form and that class file is used by JVM to convert it into an object file After that you can see the final output on your screen Any machine with Java Runtime Environment can run Java Programs In short the Java source code can run on all operating systems Therefore Java is a platform Independent language Uses and Applications of Java•Mobile App development Java is supported by Android Studio which helps facilitate secure and efficient development for a wide range of mobile applications It becomes much easier for developers to develop android applications such as Spotify and twitter with the use of Java •Game development Java is often used by game development companies because of its support for the open source most powerful D engine which provides unequalled capacity in designing D games The most popular games developed using Java are Minecraft Mission Impossible III etc Bear in mind that some developers avoid developing games using Java because of its garbage collection issues which results in performance problems and frequent pausing in the apps It is riskier to use Java for the development of bigger AAA games due to this very problem •Cloud based Applications A cloud application is an application that involves data processed on a cloud server Thanks to factors like top notch performance scalability and reliability Java has been able to provide the environment to develop cloud based applications providing low cost services to its users There are many types of services that use cloud computing with the aid of cloud apps like Dropbox Amazon Web Services Slack and Salesforce for storage and file sharing purposes Gmail for instance is an example of a cloud based application built with Java •IoT devices IoT is a technology that connects the devices in its network and communicates with them without human intervention Combined with technologies like Artificial Intelligence AI Java can help power devices remotely connect appliances and other objects through devices such as health gears smartphones wearables smart lighting TVs etc The IoT is also applied in many industries including healthcare security supply chain management and others IoT programmers gravitate towards Java because it is secure flexible and versatile •Web applications Web application development was one of the first uses of Java and it still remains a first choice language for this because of its security scalability and high performance Due to these factors many businesses large and small turn to Java when they are looking for a quick turnaround for a high performance web application Using this technology users can develop a variety of applications such as LinkedIn AliExpress web archive org IRCTC etc •Scientific applications Fields like healthcare and research use Scientific applications frequently to integrate and use math to perform practical real world computations and calculations Java is often used for creating these apps because they depend on accuracy reliability security and not to mention high performance They can access plenty of support and receive help with troubleshooting •Enterprise Applications This software is often used for enterprises large businesses that need streamlined services delivered in one place because it connects and gives access to various departments and employees There is also an entire set of Java Application Programming Interfaces APIs for enterprises called Java Platform Enterprise Edition Java EE that facilitates efficient and easy scripting Its platform independence supports company wide integration and compatibility making delivery more convenient Scalability in Java also makes it easier for growing enterprises to keep up with their efforts •GUI applications GUI applications can also be developed using Java because it provides frameworks such as AWT JavaFX and Swing which enables developers to design create test debug and deploy Rich Client Applications RIAs that behave consistently across multiple platforms CONCLUSIONAt this point readers should be able to understand the basic concepts of Java such as its definition architecture features components platforms and its applications Note that Java is not the same as JavaScript although they are often compared to each other Java is a programming language that creates applications that run in a virtual machine or a browser while Java Script is a scripting language that runs on a browser only These are some of the core upgrades done as a part of Java and release respectively Java •Ease of Use•Increased productivity by providing Optional Classes feature Lambda Expressions Streams etc •Improved Polyglot programming performs the same operations in multiple programming languages •Improved Security and performance Java •Standardized http client•Lazy Allocation of Compiler Threads•Enhanced KeyStore Mechanisms•Updated Locale Data to Unicode CLDR v•JEP Low Overhead Heap Profiling•Includes support for Unicode •JEP Launch Single File Source Code Programs•JEP Nest Based Access Control•Added Brainpool EC Support RFC •JEP Transport Layer Security TLS	2021-10-30 17:10:14
