Cloud Native Tools Highlight *

  • Twingate makes zero trust network access easy to deploy, even easier to use, and always secure.

  • Pulumi, a leading IaC tool, takes center stage by offering a modern approach, enabling users to define, deploy, and manage infrastructure using familiar programming languages. With Pulumi, infrastructure provisioning becomes more intuitive, scalable, and adaptable, bridging the gap between traditional IaC solutions and developers' expertise in languages like Python, JavaScript, or TypeScript.

  • Komodor is the Only Unified, Dev-First Kubernetes Platform. Easily Operate, Troubleshoot & Optimize Your K8s Applications.

  • [Site 24

](https://www.site24x7.com/index2.html?utm_source=WeMakeDevs&utm_medium=Youtube&utm_campaign=Site24x7demo) is AI-powered monitoring for modern IT. It monitors, visualizes, and troubleshoots your IT performance bottlenecks from one console.

  • Dragonfly is a modern replacement for Redis and Memcached. Dragonfly's novel architecture vertically scales to support any workload limited only by the physical properties of the underlying hardware. This makes Dragonfly simple to run, monitor, and scale, which also translates to overall cost savings.

  • Terramate: Supercharge Terraform with Stacks and Code Generation adds powerful capabilities such as code generation, stacks, orchestration, change detection, data sharing, and more to Terraform.

  • Kubewharf

  • Helm file declaratively deploy your Kubernetes manifests, Kustomize configs, and Charts as Helm releases. Generate all-in-one manifests for use with ArgoCD.

  • RBAC Manager is an operator that supports declarative configuration for RBAC with new custom resources. Instead of managing role bindings or service accounts directly, you can specify the desired state, and RBAC Manager will make the necessary changes.

  • Explore Aiven's fully managed open source data platform.

  • Create AI-generated infrastructures with Pulumi AI.

  • KubeSlice – the world’s first "Service Connectivity Fabric" for Kubernetes. Create virtual "stretched" clusters that connect pods across distributed cloud environments. Learn more about it here.
