Vaadin announced Vaadin Flow 23.3, a new release that makes it easier to deploy
and run stateful Java applications in Kubernetes and cloud environments. Two
new Acceleration Kits for Kubernetes and Azure Cloud enable horizontal
scalability, high availability/failover, non-disruptive rolling updates, and
session replication for both on-prem and cloud-based Kubernetes environments.
The release also adds three new UI components -Spreadsheet, Tab Sheet, and
Tooltip -bringing the total number of Vaadin UI components to fifty.
Vaadin
Flow is a unique full-stack framework that lets Java developers build and
modernize business applications without writing HTML or JavaScript.
Applications built with Vaadin Flow provide a modern browser-based user
experience while leveraging the power of Java.
"As
companies seek to modernize their Java applications, they often want to deploy
those applications into Kubernetes and cloud environments. However, until now,
it has been difficult to gain all of the benefits of the cloud with traditional
stateful Java applications," said Steven Grandchamp, CEO of Vaadin. "With this
release, Vaadin Flow customers can now easily take advantage of the
scalability, high availability, and rolling deployments common in cloud-native
applications. This reduces development time and provides valuable business
benefits, including lower operational costs, improved business continuity, and
increased agility. "
Streamlining Deployment and Scaling in Kubernetes and Cloud
Vaadin
Flow 23.3 includes an expanded Kubernetes Kit and a new Azure Cloud Kit that
provides a robust set of capabilities for running stateful Java applications in
cloud environments. They:
- enable non-disruptive
rolling updates that don't interrupt user sessions, reducing the cost and
inconvenience of after-hours deployments;
- save on cloud costs by allowing an application
to scale down without impacting active users;
- reduce downtime risk by
enabling high availability architectures that failover in case of outages;
- include session replication
along with "serialization helpers" that make it faster and easier for
developers to leverage horizontal scaling and failover fully;
- optimize the deployment of Vaadin Flow applications
to Azure with out-of-the-box Terraform blueprints that automate best practices.
New UI Components Added to Vaadin's Library of 50 components.
Vaadin's
rich library of UI components combined with Vaadin Flow allows Java developers
to create a productive user experience without learning JavaScript or new
front-end frameworks. The new components include:
- Spreadsheet, which enables
developers to have interactive spreadsheets in their apps;
- Tab Sheet, which allows
developers to organize UI components into tabs;
- Tooltip, which makes it easy
to add informational pop-ups when users hover over an input field or click a
help button.
Vaadin
Flow 23.3 is available now, and the new Acceleration Kits and UI components are
available with certain subscription levels.
Hilla, a second framework from Vaadin, now supports React
In
addition to its Flow framework, Vaadin also maintains Hilla, an open-source
framework for building business applications using a TypeScript front end and
Java back end. Vaadin recently announced Hilla support for React, the most popular JavaScript
library for building high-performance front-end applications. Hilla complements React by
providing a platform enabling application teams to create business applications
more quickly than with React alone.
