Why Kubernetes is The New Application Server

Have you ever wondered why you are deploying your multi-platform applications using containers? Is it just a matter of “following the hype”? In this article, I’m going to ask some provocative questions to make my case for Why Kubernetes is the new application server.

You might have noticed that the majority of languages are interpreted and use “runtimes” to execute your source code. In theory, most Node.js, Python, and Ruby code can be easily moved from one platform (Windows, Mac, Linux) to another platform. Java applications go even further by having the compiled Java class turned into a bytecode, capable of running anywhere that has a JVM (Java Virtual Machine).

The Java ecosystem provides a standard format to distribute all Java classes that are part of the same application. You can package these classes as a JAR (Java Archive), WAR (Web Archive), and EAR (Enterprise Archive) that contains the front end, back end, and libraries embedded. So I ask you: Why do you use containers to distribute your Java application? Isn’t it already supposed to be easily portable between environments?

DesOps is “DevOps 2.0”

As we discussed in the last post, most of DevOps today focuses on the process blocks that mostly impact engineering or technical aspects of a product rather than the design aspect. Even though  DesOps was primarily born out of the primary need of how to design at scale, the factors that shaped it are of a similar nature to the factors that shaped DevOps.

With recent software delivery processes, for example, the Agile process and Continuous Integration (CI) and Continuous Deployment (CD)of code, the DevOps approach provided a faster highway to ensure faster delivery with low risks. So the earlier SDLC model got redefined over time with Agile and then with DevOps to its current shape.

However, because design is an integral part of any product delivered, there is a need to ensure that gaps are bridged between the traditional design lifecycle and the fast track of the DevOps development lifecycle. DesOps and DevOps both are complementary to each other. The design delivery process improvements try to optimize the overall delivery process and thereby contribute to DevOps, for example, in aspects such as testing of the product that involves design aspects, usability, accessibility, etc.

The need for tighter integration between the design team and the engineering team became a necessity to ensure to design at scale. During the past two to three years, the top five big companies have made heavy investments in this area that have paved the way for other organizations and design communities to be more explorative in this area.

DesOps – The Next Wave in Design

DesOps, aka. DesignOps, refers to an approach to design that is inspired by the culture of DevOps. In this and the following posts, we will explore, the practical approaches for

  • How to prepare for the next wave in design that compliments the DevOps concepts of a cultural shift, collaboration, and automation.
  • We will also see what solutions are available today that contribute to bringing the full circle of design in the context of the software development lifecycle.

Today, design as a discipline is getting more and more recognition across the entrepreneur world and many industry efforts, such as IBM‘s Enterprise Design Thinking framework, RedHat‘s Open Studio and similar ones, are at a large scale, trying to create a synergy between the Agile approach to the software development lifecycle and the Design Thinking.  It is an interesting crossroad where the next big thing in product delivery is to bring scalability as well as automation to the creative process.

In the context of the software industry, I always see “design” as an intersection between creativity and technology where both shape each other—with help from user needs—and blend the results into successful products.

Any typical software product that is delivered involves many complex as well as divergent technologies, processes, people, and visions. Though software delivery mostly happens with team members segmented into two major groups—developers and designers—ultimately, the best outcome always depends on how the two teams communicate with each other and how efficiently their thoughts and ideas are shared, propagated, and translated.

Red Hat Summit Spotlight: Getting Started with Cloud-Native Apps Lab

Cloud-native application development is the new paradigm for building applications and although is it often mistaken for microservices, it is much more than that and encompasses not only the application architecture but also the process through which applications are built, deployed, and managed.

New apps are often seen as the focus of cloud-native applications; however, we believe existing and new applications are alike and can incorporate cloud-native practices if they have the four defining characteristics of cloud-native applications:

  • Service-based: Build modular loosely coupled services (for example, microservices).
  • API-driven: Expose services via lightweight technology-agnostic APIs.
  • Containers: Package and deploy in containers as a portable unit of compute.
  • DevOps: Adopt agile and DevOps principles.

The Getting Started with Cloud-Native Apps lab at Red Hat Summit 2018, which takes place in San Francisco on May 8–10, has a packed agenda that focuses on walking participants through the principles of building and operating cloud-native applications.

Inside a Red Hat Open Innovation Labs Residency (Part 3)

This article is the final in a series taking readers on a journey to peek inside life in a Red Hat Open Innovation Labs residency.

This is the top-tier experience for any customer*, exposing them to open collaboration, open technologies, and fast agile application delivery methods.

This experience often escapes organizations attempting digital transformation, so through submersion in an Open Innovation Labs residency, Red Hat shares its experience in managing, developing, and delivering solutions with communities, open technologies, and open collaboration.

Join me as I share experiences from inside a real-life residency, watching Red Hat work intimately with a customer, exposing new ways of working, leveraging open technologies using fast, agile application delivery methods and open collaboration.

In the first part, I shared what’s in a Red Hat Open Innovation Labs residency. Then in part two, I looked at what I encountered as the residency progressed towards delivery. All that’s left now is to share the delivery week, known as Demo Day.

Istio Dark Launch: Secret Services

“Danger is my middle name” is great for spies and people of mystery, but when it comes to deploying software, boring is better. By using Istio with OpenShift and Kubernetes to ease your microservices into production, you can make deployment really, really boring. That’s good.

[This is part seven of my ten-week Introduction to Istio series about Istio, Service Mesh, Red hat OpenShift, and Kubernetes. My previous article was Part 6: Istio Chaos Engineering: I Meant to Do That.]

Boring Is Good

Not to worry, dear DevOps person; there are some exciting things in store for you. It’s just that the end result, thankfully, is boring. You want the fun of setting things in motion and then the routine of watching it just work.

SnowCamp 2018 Trip Report

Last week, Red Hat was present at the SnowCamp conference in Grenoble, France. The SnowCamp is a technical conference that includes a unique combination of deep dive sessions (universities), technical talks, and a final day on the ski slopes. With around 400 attendees and 70 sessions, this third edition of the SnowCamp was a great opportunity to meet the developers from the Grenoble area, in the most innovative city in the world (Source: Forbes  and Mashable). Red Hatters presented 2 universities and 7 talks covering many projects and products, such as OpenShift, Infinispan, Monitoring, and Containers.
Let’s have a look to them.
