Cloud agnostic refers to a cloud design strategy in which applications, tools, and services are designed to migrate seamlessly between multiple cloud platforms or between on-premises and cloud in a hybrid model without disruption of service. Some of the tenets of a cloud-agnostic approach are to support seamless portability independent of the underlying operating system, to ensure limited disruption of the workloads in migration, and to limit the risk of application downtime while enhancing cost efficiencies. The company is run by [Emil Dabrowski](https://www.linkedin.com/in/dbrski/) and was founded in April 2021. + +## Expertise + +Cloud Native: + +- [FluxCD](https://fluxcd.io) +- [Grafana](https://grafana.com) +- [Helm](https://helm.sh) +- [Kubernetes](https://kubernetes.io) +- [Prometheus](https://prometheus.io) +- [Thanos](https://thanos.io) +- [Tekton](https://tekton.dev) + +Cloud providers: + +- Amazon Web Services (AWS) +- Azure + +Database engines: + +- MariaDB +- PostgreSQL + +Programming languages: + +- Bash +- Terraform +- Python +- Ansible + +Networking: + +- DNS +- Routing +- Firewalls +- VPNs + +Operating systems: + +- Debian +- Ubuntu +- Manjaro +- Amazon Linux + +Platforms: + +- Docker +- Proxmox +- vSphere diff --git a/content/about/index.sv.md b/content/about/index.sv.md new file mode 100644 index 0000000..b076586 --- /dev/null +++ b/content/about/index.sv.md @@ -0,0 +1,67 @@ +--- +title: "Om oss" +date: 2022-12-01T18:04:49+01:00 +draft: false +description: "Om JILITS" +# images: ["/Apple-Devices-Preview.png"] + +lightgallery: true + +math: + enable: true +--- + +![Hoggar Mountains](/img/wp2535788-1280px.jpg) + +## Bakgrund + +JILITS är ett kristet konsultbolag med fokus på serverapplikationsdrift med ett molnagnostisk tillvägagångssätt. Molnagnostisism hänvisar till en molndesignstrategi där applikationer, verktyg och tjänster är utformade för att migrera sömlöst mellan flera molnplattformar eller mellan on-prem och moln i en hybridmodell utan avbrott i tjänsten. Några av grundsatserna för ett moln-agnostiskt tillvägagångssätt är att stödja sömlös portabilitet oberoende av det underliggande operativsystemet, för att säkerställa begränsade avbrott i arbetsbelastningen vid migrering, och att begränsa risken för programavbrott samtidigt som kostnadseffektiviteten förbättras.
