From YouTube: CLOUD NATIVE JOURNEY OF JAVA EE APPLICATIONS WITH LIBERTY RUNTIME.

Description

An IBM OSS project "Open Liberty" and its product version "WebSphere Liberty", are lightweight, high-speed, next-generation application servers that support the latest Jakarta EE and MicroProfile specifications. Fully modulized runtime, Liberty provides a rich set of features, and allows you to select just the features you need with a minimal disk and memory footprint. This session introduces how your existing Java EE systems can be adapted to the cloud-native world with Liberty runtime.

A

Yes,, the URL has changed,, so Mr. Tanaka from IBM will bring Jakarta E to the cloud-native world.

B

B

I am Takakiyo Tanaka from IBM Japan. I have been in.

B

Charge of technical sales for web ski application servers and other products for over 20 years., A.

B

Lot of companies and products have come and gone, acquired and acquired,, but from the very beginning, ibm's consistent application. Server is Wealth,, but you've.

B

Heard the name Webshare. I think that there are many people who have never actually used Web Care,.

B

Even though they have it. Those, who have the impression that Airroom's web sharing is a very heavy and bulky software that you have to pay a lot of money to use. To be honest,. I think there are many,, but the image is actually very different from the actual one.

B

Websia has been.

B

Offering a new runtime called Liberty since 2012, 10 years, ago.

B

B

Next-Generation application server that's been redesigned from the kernel to fit the cloud-native era. Traditional.

B

Web sharing. And, the.

B

Disaster prevention functions that have been implemented over many years of version upgrades are always enabled, and it.

B

Was implemented in such a way that it would take from tens of seconds to several minutes in such an environment, even in orbit. On, the other hand, Liberty is completely modular and extremely lightweight. Only. The configured functions are effective. It's.

B

Designed to start up in a few seconds or so. The amount of usage has also decreased considerably. It.

B

Also occupies a very small percentage of the disk space, and.

B

Installation and fairness have become extremely easy. You.

B

Can use it freely, whether it is for study purposes to acquire your own skills or for use in business applications in a production, environment.The open source version of Liberty is called Open Liberty.

B

Unlike GPL, OpenLiberty's license.

B

Is provided under the EPL Eclipse Public License,, which is easy to use in business when it is obliged to disclose the source code of the derived part.

B

Wealth and Liberty are provided as commercial versions with support from Open Liberty,, which is updated on a schedule, basis and releases new versions. 12 times a year. It.

B

Often takes a few months, or even a year or more, from the release of a new feature in the source to the.

B

Production version. Liberty is also updated. 12 times a year, and the.

B

New features added in the open source version are now.

B

Available with immediate support, even in the commercial version released at the same time.,.

B

A

B

The upcoming Jakarta exhibition,, if you can get the beta from Open Liberty,, you.

B

Can immediately use the product version with support.

B

Functions that work with Z can be used from applications with only some functions. Most vendors provide the same APIs and server functions.

B

Unless, you use some functions of such product, employment, You.

B

Can use the exact same applications, configuration, files,, etc. in the open source version and the retail version. You.

B

Can switch the execution environment to the product version by simply rewriting 12 lines of open source projects and tocker files. It.

B

Can be kept very lightweight.

B

Apis that can be used from applications and functions provided by the server are.

B

Provided in modules called individual features.

B

Only, the module is loaded into memory and shipped It.

B

Is a javae application server that provides many functions,, but it can achieve a short startup time of 1. Second to several seconds.

B

Also,, the amount of memory used is comparable to that of lightweight frameworks.

B

Also,, this feature not only does not load into memory,, but it also.

B

Allows you to select only the functions you use and copy them to the production environment or put them in a container. It's.

B

Designed to reduce not only the memory footprint,, but also the disk, footprint. The.

B

Kernel-Like OpenLiberty distribution file size without any features, is just over.

B

11Mb. can be added,, but this is expanded and specified in this configuration file. Jacksrs2.1 Then transport security, 1.0 By, adding this,.

B

Restful web services can be provided with https If. You build an environment that.

B

Only adds the necessary items for this feature,. The size after deployment is only a little over 40MB. The.

B

Size is increasing,, but even so, there are almost no more than 100 people. Liberty is.

B

Very easy to configure. You.

B

Don't need to make any settings using .Basically,. All configurations can be done just by directly editing the file.

B

Well then, the default values. are fixed for all the items that can be set, and the.

B

Product is designed in such a way that you only need to write in the file what you want to change from those defaults. In addition,, the.

B

Traditional web sphere has a lot of environment-specific information contained in the configuration file,, and the configuration created in one environment can be copied to another. Environment. It was extremely difficult to do this,, but with this Liberty, there.

B

Is almost no need to write environment-dependent content, or it is possible to export it as an environment variable,, so it can be used in different environments. Or. You can easily copy it to another OS.

B

This property is a great advantage when trying to use various tools such as deboffice or cdcio.. It is.

B

Possible to deploy in various environments by simply copying this file, etc. from the tool of.

B

B

17,, which is the long-time support of 17, or the latest version of 18. These, are also supported in the next month's version, when those environments were officially released.

B

E 9.1 was also implemented in December last year,, the fastest in the industry. By the way,. This version is also the reference implementation of the Jakarta Tai specification.

B

However, the latest version 5.0 of this Micro Profile, will also be.

B

Supported in January 2022, immediately after the official announcement of the official version. As, you can see,.

B

Liberty is the fastest in the industry,. So it will be the optimal application execution environment for developers who want to try out various new pays.

B

By, the time the event is held,, the official version will already be out,. So as for the Carta committee, Liberty.

B

Is responding to all new issues with the Beitner β track. It is.

B

Planned that an officially supported version will be released in , or I, think it will be released in the next version. To be honest, I.

B

Think there are already a lot of customers who say that they don't want so much support for the specifications, and that they would be happy if they would support the.

B

Specifications that they are currently using for as long as possible.

B

In general application servers, when the version goes up and, for example,, it responds behind a new servlet,. The execution environment of the servlet itself will be updated,, and it will always be necessary to support new specifications.

B

However, in Liberty,, which is composed of modules,. Support for new specifications is.

B

Always done by adding new features,, not by replacing existing features.

B

If you configure it so that it uses the features of conventional use,. You can run the applications that you have been using without any changes. It.

B

Becomes a unique function.This, 0 piece gratification policy.

B

Shows a very large power in dealing with the change of namespace when migrating to the new Jakar specification. As, you know, Jakarta. Until 8 of the committee,, the.

B

Api defined in the javax package was used., Jakarta, 9 and later APIs are provided with package names that start with Jakarta.That 's why,.

B

When you want to migrate a conventional application to Jakarta, EQ or later,, you need to multiply the Japanex package name, slightly. Yes,.

B

If it's Liberty,, you.

B

Don't need to change the version or runtime type before and after the namespace change.

B

For example, this Servlet, 4.0 or JSP2.3.

B

Api up to javae 8 If, you describe this specification in front of Sabae,. The.

B

Program written in the javax package will run as it is.

B

Jakarta, A9.1's, API, Servlet, 5.0, or JSP will be named. This page, or JAXA's specification.

B

Will be changed to a name such as Restful Web, Service.

B

If you describe it in xml,, you can run applications written in Jakarta, packages.

B

It's, not something that can't be done,, but it's.

B

Possible to migrate each application to the Jakarta namespace one by one at the time it is needed by the application, and apply the configuration file at that time.

B

Liberty is a micro-profile. The.

B

Micro profile is a specification that changes very quickly,, but this is also.

B

True. It supports not only profiles, but also all specifications of Jakarta E. These can be.

B

Used in any combination.

B

B

B

Jpa to access the database from a microservice application used in Micro Profile.

B

In addition to being able to achieve more throughput with the same server resources,, it is.

B

B

Very easy to incorporate modern development and operation styles such as debops or platform code. Also,. The compatibility with the container environment is extremely high.. This.

B

Is also a great advantage when used in a container environment. Also,, we are currently developing a function that will reduce the startup time to less than one second,, and we have.

B

Requested that we be able to achieve this. For the.

B

First time,, it will be possible to use serverless functions, such as starting a container image.

B

With this, Liberty has the great power of being able to apply jave applications to those environments,, even in the future container era and cloud native era. I.

B

Believe that javainer Jakarta E will continue to be one of the favorite technologies, even in cloud native environments., I.

B

Think that, even as we continue to change and progress,, we can continue to use it in the field of application. Development. will.

B

Start providing new features while maintaining its compatibility In that sense, it is a very symbolic release., At Liberty,. We will continue to evolve so that we can develop IT systems with peace of mind, while maintaining both high compatibility and newness.

B

Ibm runs a community where you can provide technical information about Liberty in Japanese and answer questions and answers.If. You are.

B

Interested in Liberty,, please join us here. If you have any.

B

Questions,, please refer to the technical, information, and.

B

If you have any.

B

Questions,, please write them. Here. Also,! If you are.
