Vi omfavner prinsippene for cloud native teknologi i både våre utviklingsprosesser og plattformarkitektur. Ved å ta i bruk disse prinsippene, har vi som mål å bygge og administrere applikasjoner som er skalerbare, robuste og svært effektive.

Vi verdsetter Cloud Native Computing Foundation sin definisjon av cloud native:

Cloud native technologies empower organizations to build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds. Containers, service meshes, microservices, immutable infrastructure, and declarative APIs exemplify this approach.

These techniques enable loosely coupled systems that are resilient, manageable, and observable. Combined with robust automation, they allow engineers to make high-impact changes frequently and predictably with minimal toil.

Viktigst av alt tvinger ikke cloud native deg til å utelukkende kjøre applikasjoner på Azure, AWS eller Google Cloud. Det kan implementeres ved hjelp av privat infrastruktur eller, mer vanlig, en hybrid løsning som kombinerer private og offentlige skyressurser.

Som din partner kan vi sørge for at applikasjonene du utvikler og infrastrukturen du bygger er "cloud native-kompatible."

Cloud native

Kubernetes er en open-source plattform for konteinerorkestrering som automatiserer utrulling, skalering og administrasjon av konteinerbaserte applikasjoner.

I Enabler anser vi Kubernetes som en utmerket plattform for å kjøre og distribuere workloads i stor skala.

Imidlertid erkjenner vi også at Kubernetes kanskje ikke er den beste løsningen for enhver situasjon. Før du bestemmer deg for å adoptere Kubernetes, bør du kunne identifisere deg med enkelte av uttalelsene under:

Hvor mange elementer kreves for utrullingen av din applikasjonsinfrastruktur?

Hvor mange utviklere består teamet ditt av?

Trenger du å orkestrere eksterne avhengigheter, som DNS, databaser eller lagring?

Er teamet ditt forberedt på å ta i bruk nye metoder og verktøy i utviklingsprosessen?

Vi er overbevist om at konteinere har revolusjonert måten programvare bygges og kjøres på.

Vi er overbevist om at konteinere har revolusjonert måten programvare bygges og kjøres på. Imidlertid er det avgjørende å erkjenne at det er mange andre, enklere alternativer til Kubernetes for å orkestrere kontainerne dine.

Å etablere et Kubernetes-kluster er bare ett aspekt av prosessen. Før du setter opp klusteret, må du vurdere nettverksdesign og hostingalternativer. Når klusteret er på plass, må du samle komponentene som kreves for å skape en velfungernde og brukervennlig plattform for utviklere.

Våre foretrukne teknologier for dette inkluderer for øyeblikket:

FluxCD: For GitOps-basert kontinuerlig levering og distribusjon.

Cert-manager: For å generere og fornye TLS-sertifikater fra leverandører som Letsencrypt.

Prometheus: For innsamling og bearbeiding av metrikker.

Hvis du er usikker på om Kubernetes er riktig for deg, eller hvis du allerede har begitt deg ut på Kubernetes-reisen, kan Enabler hjelpe deg med å fastslå og etablere en passende løsningen for dine behov.

En effektiv plattform understøtter ikke bare DevOps, men sørger også for at utviklere kan fokusere på å levere forretningsverdi.

En vanlig misforståelse av termen DevOps er tanken om at utviklere bør håndtere alt, fra de første utviklingsstadiene til den endelige hostingen av applikasjonen. Denne oppfatningen reflekterer imidlertid ikke en effektiv arbeidsflyt. Vi lener oss i stedet mot ideen om å etablere av plattformer som letter og understøtter DevOps. 

I teknologiverden har begrepet "plattform" blitt en noe overbrukt klisjé som ofte gjør at definisjonen blir uskarpt og feiltolket. Forskjellige mennesker kan tilskrive ulike betydninger til den, noe som gjør konteksten i programvareutvikling litt forvirrende. 

For å avklare enhver tvetydighet rundt bruken av ordet "plattform" har Cloud Native Computing Foundation (CNCF) publisert en innsiktsfull whitepaper som beskriver hva "plattform" betyr innen programvareutvikling.

Reduce the cognitive load on product teams and thereby accelerate product development and delivery.

https://tag-app-delivery.cncf.io/whitepapers/platforms/

Det vi mener med termen "plattform" i denne sammenhengen er et system som inneholder de nødvendige komponentene en utvikler trenger for å distribuere, overvåke og skalere en tjeneste. Skjønnheten ved en slik plattform ligger i muligheten til å abstrahere vekk de intrikate detaljene i det underliggende systemet, slik at utviklere kan fokusere på sine kjerneoppgaver; å skape og innovere, uten å måtte dykke ned i de tekniske kompleksitetene.

I korte trekk støtter konseptet med plattformer en DevOps tankegang ved å forenkle prosesser, og sikrer dermed et mer strømlinjeformet, effektivt og samarbeidsorientert miljø for programvareutvikling. Det handler ikke bare om å tilby verktøy; det handler om å skape et økosystem som tillater DevOps å komme til sin rett.

Several days have passed since this year's 

, providing an opportunity for reflection. 

KubeCon is an exceptional conference, offering a wealth of valuable content.

This year we made sure we arrived early enough to also catch all of the amazing talks in the 

-hosted co-located events happening the day before the main KubeCon event.

Year after year, KubeCon reveals intriguing trends. This year, we observed the rapid integration of AI into cloud-native and 

While many are currently working with AI, the challenge resides in creating a robust DevOps narrative around AI and transitioning projects into production.

This is where Kubernetes and cloud-native technology could offer a solution to these challenges.

 is another trend. It appears that WASM is increasingly popular, with many major projects already using it in production.

Its name can be misleading, as its use extends beyond just web browsers.

Web Assembly appears to be, and increasingly could become, a common compilation target for numerous languages.

This would facilitate smaller binaries, a security sandbox, a shared runtime, and platform-independent packages.

With a really small footprint and startup time this could fit very well into a lot of applications.

Kubernetes on the edge was also something that got a good amount of attention.

 seems promising and definitely something we will dive more into.

Our personal highlight was perhaps the talk from Cloud-native-startupfest, which was called “Fireside Chat with Kelsey Hightower and Alex Polvi, CEO, CoreOS, Inc”.

Amazing insight into a really remarkable journey that gave us a lot of inspiration!

As with the previous year, security remains a crucial topic that received substantial coverage at KubeCon. 

We found the Capture The Flag event hosted by 

 both valuable and entertaining, offering a welcome break from sessions.

Beyond learning, KubeCon is a great place to connect with community members.

We particularly enjoyed meeting both new and old friends at the Nordic Cloud Native Meetup and the Norwegian rooftop lunch!

We're already looking forward to next year!

Insights from KubeCon 2024: Trends, Highlights & Community Connections

In October 2022, we’ve decided to create a unique brand and website for Enabler that aligns with our values. 

 for just a basic website with information about the company.  So in October we’ve got in contact with absolutely brilliant designers that helped us create new brand for Enabler.

We've collaborated with great designers, 

 from Poland, to create a brand new website design.

, specialised in Design Systems and Artur is 

. They have a lot of experience, and after our initial meeting, we were confident that we wanted to collaborate with them for the upcoming months.

So we started having workshops led by Matt to find out what our values, goals, and purpose are behind what we do. 

After several workshops, discussions, and rounds of feedback, Matt supplied us with ready-to-use 

The Brand Guidelines provide information about colors, typography, and logos.

Meanwhile, Brand Elements include social media profile pictures, cover images, email footers, resume templates, and desktop background images, among others.

And once our brand was ready the next step was to create a new website for Enabler. 

Following several meetings with Artur, he grasped the type of website we desired and crafted a stunning design that incorporated our new fonts, colors, and logo.

The entire branding process took about three months. Our developer, Dominika, then took over and began implementing the new design on the website.

It was important for us to create a responsive and fast website using modern technologies. Here are the technologies we used to create the website:

 is powerful framework for building performant, scalable and maintainable web applications. It allows us to generate static HTML files at build time, which improves our site's performance and reduce hosting costs. It makes the website much quicker, comparing to other solutions.

It has a great solution for optimising images for different devices and screen sizes. 

It offers lazy loading to enhance page load times and priority image loading. This prioritizes the loading of essential images on the page, ensuring they load as quickly as possible for an improved user experience.

Another important solution is the font loading optimization library, next/fonts. It enhances the performance and usability of a webpage by optimizing how fonts are loaded and rendered.

, because it helped us develop our webpage faster, using pre-defined utility classes, that we used to quickly apply styles to HTML. 

We can easily customise these classes by adding our own colors, fonts, and other to the Tailwind config. This allowed us to create a unique design for our website.

Tailwind CSS also supports styling any vanilla HTML that we cannot control, such as content from articles pulled from CMS. 

. This plugin offers a set of prose classes that can be used to apply default styles to headings, blockquotes, links, and more.

Tailwind CSS makes it easy to maintain a consistent, responsive design and user experience throughout website.

 is a headless CMS (Content Management System) that we used on our website. 

It allows us to define custom data models, so our data is organised the way we want, making it easy to work with. 

, as one of the dependencies to retrieve any crops or hotspots present in the Sanity content.

We can specify the width and height to get cropped and resized image according to the wishes of the content editor. 

We can also specify the format or quality to obtain the most optimized images.

Next/image combined with @sanity/image-url:

 to create unique images on our website. 

Midjourney is a generative artificial intelligence program and service. It's created and hosted by Midjourney, Inc., an independent research lab located in San Francisco. Midjourney generates images from natural language descriptions, which are called "prompts."

We are very pleased with the outcome. Hopefully, you will like our new webpages and profile as much as we do!

Revolutionizing Enabler: Branding & Web Design Journey

Venturing into the world of deploying an MQTT broker in Kubernetes can lead you to some intriguing challenges, especially when compared to the more traditional tasks of serving webpages or APIs

Unlike HTTP-based services, MQTT is served over TCP. Consequently, some common ingress solutions, such as ingress-nginx, do not natively support serving TCP traffic. We'll explore how we could bypass this limitation.


Ensuring secure communication between the MQTT broker and clients is crucial. However, manually creating and managing SSL certificates can be a tedious process. We'll demonstrate an automated method for managing SSL certificates, making your MQTT communication secure and worry-free

First things first, let's generate the certificate we want to use. The "de facto standard" for this task is cert-manager, and we'll use a cert-manager-generated certificate in the same way we do with other ingress-generated certificates. This ensures the certificate stays up-to-date.

As long as your DNS points to the Ingress controller's load balancer for the specified host making it possible for cert-manager to validate your host, you should have a secret containing the certificate in your cluster.

Now, it's time to deploy an MQTT broker. Although we often prefer cloud-native brokers like EMQX, we've opted for Mosquitto in this example due to its simplicity.

We'll refer to the generated secret when specifying the certificate location in the config. 


Keep in mind that the example above allows anonymous access to the broker. In a production environment, you'll need to secure your endpoint with an ACL, password list, or similar method and disable anonymous access.

After deploying the components mentioned above, you should have a working MQTT broker with a certificate securing it. However, it's not yet accessible from outside since TCP traffic isn't routed by ingress-nginx.

To overcome this, we can leverage a lesser-known feature in ingress-nginx that allows routing specific ports to TCP services within the cluster. Note that we're not using any host headers here, so any request to any host pointing to the ingress service will be routed on the specified port.

https://kubernetes.github.io/ingress-nginx/user-guide/exposing-tcp-udp-services/

To do this we will use a configmap called tcp-services to keep track of routed ports.

The last part is to tell ingess-nginx to read the configmap and allow port 8883 into to load balancer. 


Add port 8883 to the ingress load balancer ports. 

Assuming you have a service named "mosquitto-mqtts" in the "mosquitto" namespace, this should route the port to the broker. Now, you're all set with a fully functioning Mosquitto MQTT broker with encrypted communication in Kubernetes. Enjoy!
