As a consistent user and developer on the OpenShift platform over the years, I’ve tried helping users by sharing my application development content as we’ve journeyed from cartridges all the way to container base development.

With container based development we’ve also transitioned from using templates to define how to deploy our tooling and applications, to operators. There are many examples of how to work with the templated versions of our applications around decision management and process automation found on Red Hat Demo Central and JBoss Demo Central.

This is the final part of our Kubernetes logging series. In case you missed part 1, you can find it here. In this tutorial, we will learn about configuring Filebeat to run as a DaemonSet in our Kubernetes cluster in order to ship logs to the Elasticsearch backend. We are using Filebeat instead of FluentD or FluentBit because it is an extremely lightweight utility and has a first-class support for Kubernetes. It is best for production-level setups.

Deployment Architecture

Filebeat will run as a DaemonSet in our Kubernetes cluster. It will be:

Docker Hub: In the News

DockerHub is a cloud-based repository where popular Docker images can be published and end-users can pull them for their cloud-native infrastructure and deployments. Docker images are lightweight and portable; they can be easily moved between systems. Anybody can create a set of standard images, store them on a repository, and share them throughout the organization. You can also use Docker Hub for sharing Docker container images. 

Docker Hub was recently in the news for the following two reasons:

Significant changes were made to the Istio service mesh in its version 1.5 release earlier this year, including notable modifications to the control plane architecture and the creation of a single model for extending Istio and its Envoy proxies using WebAssembly. Istio’s latest quarterly release, version 1.6, at first glance may seem to carry less weight in comparison, however, this update includes several important enhancements that continue to improve its operability.

Installation and Configuration Management

Reducing Upgrade Risks

Istio 1.6 introduces canary support for upgrading versions of the Istio control plane, enabling users to deploy numerous releases of Istiod within the same cluster and migrate pods to a newer version. This will significantly reduce any risks that arise when carrying out upgrades in a production cluster. When installing new control plane versions, the istioctl the command-line tool now supports assigning names to versions that can be utilized when assigning workloads to each specific Istiod version running in the service mesh.

The biggest trend we’re talking about this month started at WWDC as Apple provided a glimpse of what’s coming next for their operating systems. This time around there’s a distinct design element. Did you catch it?

Here’s what’s trending in design this month.

1. Text Highlights and Underlines

There’s always been an unwritten rule in website design that text uses more plain styles. Bold is acceptable, italics are OK from time to time, but underlining is seldom used.

This design trend bucks that concept with text elements that use highlighter or underline elements to emphasize key words. And it works rather nicely.

What it takes to make this work is plenty of contrast and a design style that fits with underline or highlighted elements.

This design trend works thanks to clear intention. The words are obviously important to the overall meaning of the design or what visitors should take away from the content.

Pepper It uses a nifty underline that the letters seem to rest inside of to highlight a key phrase. The shape and color also mimic that of the larger button below, helping the eyes move from one element to the next. It’s an effective use of an underline (or maybe you could call it a highlight) effect in conjunction with brand colors.

Zappos Kids uses a fun highlight in a colorful scheme to highlight a key text element. It almost looks like a button and helps website visitors understand that the entire hero image area is clickable. The highlight serves to make the text more readable and the interactive element more functional.

Zeus Jones uses a variety of text treatments on the homepage, but arguable the underline is most noticeable, likely because it is the most unfamiliar in the context of website design.

2. Distinct Geometry

Geometric shapes in website design have popped up as trending elements in a variety of forms. This iteration is pretty simple: Use of distinct geometry as part of the overall aesthetic.

Geometry might pair with illustrations, photos, text, or in the background or foreground. What’s great about shapes is that they are versatile and work with a lot of other design patterns.

What can be the most challenging about shapes and design is that distinct geometry requires some space and thought. Just tossing a few triangles or rectangles in a design without reason can look rather strange.

So how can you add geometric shapes to a design so that they look intentional? These examples do it well (and in three different ways).

Rui Ma uses square and rectangular containers in a modular grid with portfolio projects inside each. This is one of the most common and applicable uses of geometry – as a container element. What makes it stand out is the circle, smiley wheel (also a geometric shape) that never leaves the center of the screen. The black background for the grid is also a nice contrast element for content blocks.

Thompson Stenning uses shapes in the background and with illustrations to create a stunning homepage visual. It’s big and bold and has just enough going on that you want to look at it and figure out the scene. Maybe what’s most intriguing about the visual concept is that it uses lots of geometric shapes – rectangles, squares, triangles, ad circles – whereas most projects pick one shape to focus on.

Romain Penchenat uses three-dimensional style angles to draw you into the portfolio website. They use a simple animation that “floats” on the homepage and follows the scroll with other geometric elements.

3. Shadow and Gradient Icons

Did you notice all the gradients and subtle shadows in icons in the images previewing iOS 14 or were you just looking at other changes (such as widgets) on the iPhone screen?

We’ve been seeing more designers incorporating more shadows and depth into icons for a while, but this move by a major player in design will push it to the forefront fast. Each of the icons moves from a flat style to one with a background gradient color as well as more shadows within icon elements for depth.

Don’t worry, the design still looks very much like Apple, but is a little more reminiscent of the skeuomorphism style icons from earlier versions of iOS.

It’s nice that the color and shadow elements are contained within each icon. This creates more visual interest and depth for each element without getting cluttered or junky. The gradients are also super simple, using a darker version of the main color in a monotone element.

It’s an iconography style that others are already using. DG Studio has a collection of icons on its homepage with subtle gradients and shadowing in the designs. Again, what’s nice about this trend is that it adds depth to visuals without tricks that get in the way of visual comprehension.

Guillaume Gouessan uses gradients in image icons in much the same way as the previous examples but with a little more color variation. Here, you can see what the gradient looks like when using a color change that’s not super drastic, but more dramatic than a monotone option. You can find some use of the more monotone gradient on his site below the scroll in the large desk image. (It’s definitely worth a few clicks to check it out.)

Love it or hate it, gradients and shadows seem to be here to stay for a while.

Conclusion

How often do you find yourself looking to major brands and companies for design inspiration? While a lot of web design trends start as experiments with smaller sites, the big players can really shape what gets popular (or not).

The example of Apple moving to icons with more shadows and gradients is a prime example. We’ve been seeing more of these elements creeping in for a while, but this style is about to get very big again.

Integrating SAAS application workflow
The previous article in this series looked at a SaaS CRM connector integration example. The foundation for this logical diagram was researching a use case where customers were successful with a portfolio solution.

It’s a starting point for the generic architectural blueprint that rises from several customer solutions that were researched. Having completed the outline of the blueprint details and the resulting logical diagram elements, it’s now time to take a look as specific examples.

In this article, we’ll continue building the previous examples by sharing how customers are integrating with third-party platforms in their architectures as SaaS platforms.

It was the early 2000’s, your .NET application was the best thing to hit the streets since the IBOOK G3 came out. Let’s just say that your application was so money, it didn’t even know it. It had its shiny new (insert any sweet .NET functionality here) and all of the Java-based applications were jealous of it. Those were the days…

Now turn to today. You feel like John Ritter and your application is the problem child from hell. It’s stuck in the past; it won’t allow you to update it. You’re constantly supporting all of its bad consumption habits and it won’t play nice with your other applications.
