VMWare Virtualization - OpenShift (Kubernetes, Ansible, Cloud; AWS, Azure, GCP - Technical Experts. ACM/ACS & ODF Freelance/contract - remote EU - Europe.

We seek a number of OpenShift VMware virtualisation experts in EU.

Freelance/contract only.

EU based - remote is OK. Some may be required to travel, depends on experience & Customer.

Ideal experience:

ACM - Advanced Cluster Management for Kubernetes

• Purpose: Centralized management of multiple Kubernetes/OpenShift clusters.
• Key Features:
• Multi-cluster management: Deploy, monitor, and govern clusters across hybrid/multi-cloud environments.
• Policy enforcement: Apply security, compliance, and configuration policies across clusters.
• GitOps support: Integration with ArgoCD for continuous deployment.
• Governance & risk: Monitor and fix policy violations automatically.
• Use Case: Ideal for organizations running multiple OpenShift/K8s clusters across on-prem and cloud.

ACS - Advanced Cluster Security (formerly StackRox)

• Purpose: Security solution for containers and Kubernetes environments.
• Key Features:
• Runtime security: Detect and block suspicious behavior in containers and clusters.
• Vulnerability management: Scan images, deployments, and clusters for known CVEs.
• Network segmentation: Enforce network policies to limit lateral movement.
• Policy enforcement: Secure development pipeline with pre-deployment checks.
• Use Case: Essential for DevSecOps and compliance in containerized workloads.

ODF - OpenShift Data Foundation

• Purpose: Provides persistent, software-defined storage for OpenShift.
• Built On: Red Hat Ceph Storage (Rook/Ceph)
• Key Features:
• Block, file, and object storage: For apps running in OpenShift
• Dynamic provisioning: Storage auto-allocates based on app requirements
• Multicloud object gateway: S3-compatible object storage
• High availability: Distributed, resilient storage
• Use Case: Needed when apps in OpenShift require persistent volumes, especially stateful workloads like databases.

Virtualization

Skills commonly associated with managing and deploying virtual machines and infrastructure:

• Hypervisors: Knowledge of Type 1 (bare-metal) and Type 2 (hosted) hypervisors (eg, KVM, Hyper-V, VMware ESXi)
• Networking: Virtual Switches, VLAN tagging, NAT, bridging, and routing
• Storage Management: NAS/SAN, virtual disk provisioning, IOPS tuning
• Resource Allocation: CPU/memory tuning, resource pooling
• Monitoring & Performance Tuning: Tools like Nagios, Prometheus, or Grafana
• Security: Isolation, secure boot, virtual Firewalls, snapshot management

Red Hat OpenShift

A container platform built on Kubernetes. Skills needed:

• Kubernetes (K8s): Deep understanding of pods, services, deployments, config maps, and secrets
• Containerization: Docker/Podman experience (building, deploying, managing containers)
• CI/CD Pipelines: Integration with Jenkins, GitLab CI, Tekton
• OpenShift CLI (oc): Proficiency in command-line management of clusters
• Operators & Helm Charts: Managing and deploying applications using Operators or Helm
• Networking & Ingress: Routes, ingress controllers, service mesh (eg, Istio)
• Security: Role-Based Access Control (RBAC), Security Context Constraints (SCC), OAuth integrations
• Persistent Storage: Dynamic volume provisioning, Ceph, NFS, GlusterFS
• Monitoring & Logging: Prometheus, Grafana, EFK/ELK stack in OpenShift

VMware (vSphere, ESXi, vCenter, NSX, etc.)

Skills associated with managing VMware-based virtualized environments:

• vSphere & vCenter: VM life cycle management, snapshots, cloning, templates
• ESXi: Host setup, configuration, patching
• NSX: Network virtualization, micro-segmentation, Firewall rule configuration
• vSAN: Hyper-converged storage, performance tuning, cluster setup
• vMotion/DvMotion: Live migration, distributed resource scheduling (DRS)
• VMware Tools & Guest OS Integration: Enhancing VM performance and management
• Automation: vRealize Suite, PowerCLI Scripting for infrastructure automation
• Disaster Recovery: Site Recovery Manager (SRM), replication strategies

Bonus: Cross-Platform Skills

• Linux Admin: Strong RHEL/CentOS or Ubuntu server skills
• Scripting: Bash, Python, or PowerShell
• Infrastructure as Code: Terraform, Ansible, or Puppet
• Cloud Integration: Familiarity with hybrid cloud models involving AWS, Azure, or GCP
