Announcing Red Hat Application Migration Toolkit 4.1.0: Now with technical reports

[In case you aren’t following the Red Hat JBoss Middleware blog, we are reposting this article on developers.redhat.com.]

Red Hat Application Migration Toolkit (RHAMT) 4.1.0 has been released, and with it a new feature that I’d like to highlight in this article—Technology Reports.

If you’re not familiar with RHAMT, check out my previous article that introduces RHAMT and describes how you can use it to help with migration existing applications to a modern application platform by analyzing your code base.

Technology reports

This new feature in RHAMT provides an aggregate listing of the technologies used, grouped by function, for the analyzed applications. It shows how the technologies are distributed. After analysis has been performed, using this report hundreds of applications can be quickly compared. In addition, the size, number of libraries, and story point totals of each application are displayed, allowing you to quickly determine each application’s type from a single report, for example:

Improving .NET Core Kestrel performance using a Linux-specific transport

ASP.NET Core is the web framework for .NET Core. Performance is a key feature. The stack is heavily optimized and continuously benchmarked. Kestrel is the name of the HTTP server. In this blog post, we’ll replace Kestrel’s networking layer with a Linux-specific implementation and benchmark it against the default out-of-the-box implementations. The TechEmpower web framework benchmarks are used to compare the network layer performance.

How to migrate your SOAP web service to REST with Camel

SOAP-based services are plentiful in many enterprise solutions and are slowly being replaced by RESTful services to simplify their use. There is a new wizard to help you make the transition with Apache Camel’s Rest DSL added in the latest version of Red Hat Fuse Tooling. This article shows how to use the new wizard to transition from older SOAP-based services to more modern REST-based services.

If you aren’t familiar, Red Hat Fuse is an integration platform based on Camel and a number of other projects. The updating Fuse Tooling is available in Red Hat Developer Studio 12.0.0, the desktop IDE that is based on Eclipse 4.8 Photon. You can also get the new wizard by adding JBoss Tools 4.6 to your existing Eclipse 4.8 Photon installation by downloading it directly, or installing via the Eclipse Marketplace.

How to install Clang/LLVM 5 and GCC 7 on RHEL

If you are developing with C/C++, Clang tools and newer versions of GCC can be quite helpful for checking your code and giving you better warnings and error messages to help avoid bugs. The newer compilers have better optimizations and code generation.

You can easily install the latest-supported Clang and GCC compilers for C, C++, Objective-C, and FORTRAN using yum on Red Hat Enterprise Linux.  These compilers are available as software collections that are typically updated twice a year. The May 2018 update included Clang/LLVM 5 and GCC 7.3, as well as Go and Rust.

If you want your default gcc to always be GCC 7, or you want clang to always be in your path, this article shows how to permanently enable a software collection by adding it to the profile (dot files) for your user account. A number of common questions about software collections are also answered.

Using OpenShift to deploy .NET Core applications

Containers are the new way of deploying applications. They provide an efficient mechanism to deploy self-contained applications in a portable way across clouds and OS distributions. In this blog post we’ll look at what OpenShift brings for .NET Core specifically.

Kubernetes and OpenShift

Kubernetes is the de facto orchestrator for managing containerized applications. Google open-sourced Kubernetes in 2014 and Red Hat was one of the first companies to work with Google on Kubernetes. Red Hat is the 2nd leading contributor to the Kubernetes upstream project.

OpenShift is an open-source DevOps platform that is built on top of Kubernetes. It integrates directly with your application’s source code. This enables continuous integration/continuous deployment (CI/CD) workflows. Tools are available to scale and monitor your applications. The OpenShift Catalog makes it easy to setup middleware and databases. OpenShift comes with comprehensive documentation to install and manage your installation. It can run on-prem and on public clouds such as AWS, GCP and Azure.

June 2018 ISO C++ Meeting Trip Report (Core Language)

The Summer 2018 ISO C++ standards committee meeting this year was back in Rapperswil, Switzerland. The new features for C++2a are coming fast now; the Core language working group had very little time for issue processing because of all the proposal papers coming to us from the Evolution working group.

Red Hat sent three of us to the meeting, to cover different tracks: myself (Core), Jonathan Wakely (Library), and Torvald Riegel (Parallelism/Concurrency).  Overall, I thought the meeting was very successful; we made significant progress in a lot of areas.

New C++ language features that were accepted at this meeting:
