The benefits of Verrazzano are:

· Improving developer productivity, through containers and container management technologies, devops, and cloud-native development. Deployment times can be decreased and application uptime increased.

· Modernizing existing applications.

· Cloud-native benefits without lock-in. Oracle says Verrazzano provides a “cloud-neutral” approach for container applications, regardless of whether they are deployed on premises, in Oracle Cloud Infrastructure, or in other public clouds.

· Intelligent workload management across clusters, with automatic provisioning of Kubernetes operators, creation of Kubernetes objects, application modeling for advanced deployment scenarios, and extended features for WebLogic, Coherence, and Helidon workloads.

· Automated, built-in observability for system and application components, including metrics and log collection from managed workloads and pre-configured dashboards.

· Application lifecycle management, with cross-cluster updates with devops and Gitops enablement to reduce overhead and improve uptime.

· Polyglot workload enablement, with application handling for Java and non-Java applications.

· Multi-platform security, with protection for network traffic, system components, and application components. News IT

Oracle Helidon taps virtual threads for ‘pure performance’

Oracle’s Helidon, a set of Java libraries for developing cloud-native microservices, is set to improve performance via virtual threads with the planned 4.00 version. Currently in an alpha state of development, Helidon 4.0.0 introduces Nima, a web server based on virtual threads, which are JVM-managed lightweight threads that can improve scalability. Virtual threads, previewed in both this week’s…

Intro to MicroStream: Super-fast serialization in Java

Intro to MicroStream: Super-fast serialization in Java

Intro to MicroStream: Super-fast serialization in Java MicroStream is a very interesting and even bold approach to data persistence in Java applications. It proposes to sidestep server-datastore complexity entirely and instead provide an object persistence layer that runs inside the application itself. Oracle has incorporated MicroStream into its Helidon microservice framework, which can be seen…

Less than a year after the formal release of Helidon 1.0, Oracle is well on their way to a formal release of Helidon 2.0 scheduled for late Spring 2020. Helidon 2.0.0-M1, released in early February, and Helidon 2.0.0-M2, released in late March, have provided the Java community previews of significant new features including: support for reactive messaging and streams; a new command-line tool, a new web client API for Helidon SE, GraalVM support for Helidon MP, and a new reactive database client.

Support for GraalVM, introduced with the release of Helidon 1.0.3, was only available for Helidon SE applications. Helidon MP applications could not take advantage of GraalVM due to the use of reflection within CDI. As one of the most requested features by the Java community, Helidon 2.0.0-M1 introduced support to convert Helidon MP applications to native executable code with GraalVM. Tomas Langer, consulting member of technical staff at Oracle, has created this demo application for the Java community to preview this new feature.

To complement the original three core Helidon SE APIs - Web Server, Configuration and Security - a new API, Web Client, completes the set for Helidon SE. Web Client processes HTTP requests and responses related to a specified endpoint. Just like the Web Server API, Web Client may also be configured via an applications.yaml file:

server: port: 8080 host: 0.0.0.0 client: connect-timeout-millis: 2000 read-timeout-millis: 2000 follow-redirects: true max-redirects: 5 headers: - name: "Accept" value: ["application/json","text/plain"] services: exclude: ["some.webclient.service.Provider"] config: metrics: - methods: ["PUT", "POST", "DELETE"] type: COUNTER name-format: "client.counter.%1$s.%2$s"

Consider a small example where an instance of the WebClient interface is built and a response defined to return plain text:

WebClient client = WebClient.builder() .baseUri("http://localhost") .build(); CompletionStage<String> response = webClient.get() .path("/endpoint") .request(String.class);

To change the response to return JSON, simply build an instance of the JsonProcessing class and change the definition of the response variable:

JsonProcessing jsonProcessing = JsonProcessing.create(); CompletionStage<JsonObject> response = webClient.get() .path("/endpoint") .register(jsonProcessing.newReader()) .request(JsonObject.class);

To address the challenges associated with reactive applications connecting to JDBC databases that, by design, are non-reactive, Helidon 2.0.0-M1 introduced the new DB Client that will provide consistent reactive database access and queries for Helidon SE applications. DB Client supports relational databases that connect via JDBC and reactive drivers for MongoDB. This new API will feature the ability to specify database connections and write native query code in a configuration file such that making database-related changes can easily be made without having to recompile code:

db: source: "jdbc" connection: url: "jdbc:mysql://127.0.0.1:3306/pokemon?useSSL=false" username: "user" password: "password" poolName: "mysql" statements: ping: "DO 0" select-all-pokemons: "SELECT id, name FROM Pokemons"

Support for metrics, health checks and tracing in DB Client will also be included. The Helidon team has created this demo application for the Java community to preview this new feature.

Introduced in Helidon 2.0.0-M2, developers can now create, build and run Helidon applications via the command line with the new Helidon CLI tool. Similar to hot reloading provided by Quarkus (quarkus:dev), a built-in development loop monitors source files that triggers a restart of the application upon changes to the source code. A separate download and installation is required. Once installed, the available command-line options are shown below:

Asynchronous messaging is an integral part of microservices applications. To that end, implementations of the MicroProfile standalone APIs, Reactive Messaging and Reactive Streams Operators, will be introduced in version 2.0. Both APIs will be available for Helidon SE and Helidon MP applications. However, only Reactive Messaging will be available for Helidon MP. To better align with the Helidon SE APIs, an equivalent Reactive Messaging API is planned for a future release. Helidon will also support Kafka for Reactive Messaging with additional connectors planned for a future release.

The Java community can expect some breaking changes with the final release of Helidon 2.0. Most notably, support for Java 8 has been dropped and JDK 11 will be the minimum Java version required for building Helidon applications. Some Helidon packages will also be removed in favor of corresponding packages found in java.util, java.lang and java.io. Details of all the changes in Helidon 2.0 may be found in the change log.
