Red Hat is shipping Red Hat Application Foundations, a set of application services that work with the company’s OpenShift Kubernetes platform and promise to accelerate the development of containerized applications across hybrid and multicloud environments.

Announced April 25, Red Hat Application Foundations serve as a toolkit for developers who are building and integrating application and data services as part of their application and infrastructure modernization efforts. It provides developers with an integrated solution for connecting applications both within and outside the container environment. Its application services and components are designed to help developers take advantage of cloud-native application patterns and accelerate the development of applications across hybrid cloud or multicloud environments.

Few computing platforms—even those of great power and scale—satisfy every need out of the box. While Kubernetes is useful out of the box, it’s far from complete. You can always find a use case or a need where the default Kubernetes feature set falls short, such as database support, or simply ignores, such as continuous delivery.

Argo CD is a popular open source, continuous delivery (CD) platform for Kubernetes that is used by hundreds of organizations globally. Recently, a serious vulnerability in Argo CD was uncovered by Apiiro , which enables attackers to access sensitive information such as secrets, passwords, and API keys. The vulnerability has been tagged as CVE-2022-24348 .

The vulnerability could allow malicious actors to load specifically configured Kubernetes Helm charts that would grant them access to sensitive information through Argo CD.

As The Innovator’s Dilemma tells us, today’s successful organizations will be increasingly challenged to adopt new processes in order to thrive. For modern organizations that rely on software development to sustain competitive advantage, this ever-present need for change requires reimagining the ways development teams work. Here at Priceline—one of the world’s most-frequented travel sites with millions of monthly visitors—that means adopting not only new and innovative technologies, but a whole new mindset around how we build and deploy services.

If we want to sustain success in a hyper-competitive marketplace, we must support a whole new set of service delivery strategies, and that requires thoughtfulness and diligence on the part of technology leadership. Our all-star team of technologists has rallied around 12-factor app development, monorepos, trunk-based development, and dependency management in an effort to lead technology evolution in the travel industry. But there’s much still to be done.

In 2013, Docker was the “it” company. Docker made headlines for the critical role it played in bringing containers to the mainstream, and in many ways displaced PaaS as the hotness of the time ( Heroku anyone ?). Now, the company is back in the press with the introduction of a new model for Docker Desktop that requires larger organizations to buy a paid subscription for the tools. There’s been a vocal reaction to this announcement , one that reminds me of the important role Docker played in popularizing a model we know, love, and now use on a mainstream basis: containers.

The promise of using Docker during development is to deliver a consistent environment for testing across developer machines and the various environments (like QA and production) in use. The difficulty is that Docker containers introduce an extra layer of abstraction that developers must manage during coding.

Docker enables application code to be bundled with its system requirements definition in a cross-platform, runnable package. This is a graceful abstraction for solving a fundamental need in deploying and managing software runtimes, but it introduces an extra layer of indirection that must be dealt with when programmers are doing what they do: iteratively modifying and testing the internals of the software and its dependencies.

Containers, certainly containers running on public clouds, are really old hat by now. These self-contained, lightweight software packages come with their own runtime environment and are relocatable from platform to platform, typically without significant changes to code. Containers include an application as well as its dependencies, such as libraries, other binaries, and configuration files needed to run them.

Containers are one of the most popular application development approaches, also supporting the “wrapping” of applications existing within containers, but there are flaws and vulnerabilities that are systemic to containers. This has made using them one of the scarier things for cloud security specialists and a preferred attack vector for wrongdoers.

“Complexity kills,” Lotus Notes creator and Microsoft veteran Ray Ozzie famously wrote in a 2005 internal memo . “It sucks the life out of developers; it makes products difficult to plan, build, and test; it introduces security challenges; and it causes user and administrator frustration.”

If Ozzie thought things were complicated back then, you can’t help but wonder what he would make of the complexity software developers face in the cloud-native era .

The term “cloud-native computing” has emerged as a catch-all for the various tools and techniques required by software developers to build, deploy, and maintain modern software applications on cloud infrastructure. Here, we define the term, survey the cloud-native landscape, and identify some of the advantages and pitfalls of going cloud-native.

Cloud-native definition

Cloud-native is a modern approach to building and running software applications that exploits the flexibility, scalability, and resilience of cloud computing. Cloud-native encompasses the various tools and techniques used by software developers today to build applications for the public cloud, as opposed to traditional architectures suited to an on-premises data center.
