Power of Infrastructure as Code (IaC)

Provisioning traditional IT infrastructure is a time-intensive and costly process. It involves setting up hardware physically, installing and configuring operating systems, and connecting to middleware, networks, and storage systems—all tasks that require skilled personnel.

Virtualization and cloud-native development address the challenge of managing physical hardware by enabling developers to provision virtual servers or containers on demand. However, provisioning virtualized infrastructure still poses challenges: it diverts developers’ attention from coding, requires repetitive setup for each deployment, and lacks robust mechanisms for tracking environment changes or preventing inconsistencies that can disrupt deployments.

Infrastructure as Code (IaC) takes automation a step further, allowing developers to “order up” fully documented, version-controlled infrastructure by simply running a script. This approach provides several benefits, including improved efficiency, consistency, and ease of tracking changes.




IaC Tools by Category

Provisioning Tools

  1. Terraform: An open-source, cloud-agnostic tool that works across multiple environments.
  2. Pulumi: A code-based IaC tool supporting languages like Python, TypeScript, and more.
  3. CloudFormation: AWS-specific tool for defining and managing AWS resources.
  4. Google Cloud Deployment Manager: A declarative tool for provisioning and managing GCP resources.

Configuration Management Tools

  1. Ansible: Agentless automation tool for configuration, application deployment, and provisioning.
  2. Chef: A code-based configuration management tool using Ruby.
  3. Puppet: A declarative tool for managing and automating infrastructure configuration.
  4. SaltStack: A scalable platform for configuration management and automation.

Container Management Tools

  1. Kubernetes (K8s): A powerful orchestration platform for managing containerized applications.
  2. Docker Compose : A declarative YAML-based tool for defining and managing multi-container applications.
  3. Helm: A package manager for Kubernetes, simplifying resource management.

Version Control and Pipeline-Oriented Tools

  1. GitOps Tools: Tools like Flux and ArgoCD that enable Git-based workflows for declarative infrastructure management.
  2. Jenkins Pipelines for IaC: For creating automated pipelines with IaC integration.

Specialized IaC Tools

  1. Vagrant: A tool for managing and provisioning virtualized development environments.
  2. Packer: Automates the creation of machine images across multiple platforms.
  3. Spinnaker: A deployment tool supporting IaC strategies in CI/CD pipelines.

By streamlining infrastructure management, IaC accelerates deployments, ensures reliability, and makes scaling infrastructure easier and more predictable.

Changing the FQDN of the vCenter appliance (VCSA)

This article states how to change the system name or the FQDN of the vCenter appliance 6.x You may not find any way to change the FQDN from the vCenter GUI either from VAMI page of from webclient as the option to change the hostname always be greyed out. Now the option left is from the command line of VCSA appliance. Below steps will make it possible to change the FQDN of the VCSA from the command line. Access the VCSA from console or from Putty session. Login with root permission Use above command in the command prompt of VCSA : /opt/vmware/share/vami/vami_config_net Opt for option 3 (Hostname) Change the hostname to new name Reboot the VCSA appliance.   After reboot you will be successfully manage to change the FQDN of the VCSA . Note: Above step is unsupported by VMware and may impact your SSL certificate and face problem while logging to vSphere Web Client. If you are using self-signed certificate, you can regenerate the certificate with...

High-Speed Networking for VMs: VMXNET3 Now Supports Up to 65 Gbps

The VMXNET3 adapter is VMware's high-performance virtual network adapter, designed for optimized performance in vSphere environments. It is the default and recommended adapter for most modern workloads on ESXi , delivering high throughput, low latency, and support for advanced networking features. With the release of vSphere ESXi 8.0 Update 2 , VMXNET3 introduces new capabilities that significantly enhance virtual network performance. What’s New in ESXi 8.0 Update 2 for VMXNET3? Traditionally, VMXNET3 reports a default link speed of 10 Gbps to the guest operating system. However, the actual achievable throughput often exceeds this value—thanks to technologies such as multi-queue support , Receive Side Scaling (RSS) , and Large Packet Offload . Starting with ESXi 8.0 Update 2 , this limitation can now be overridden , and VMXNET3 can be configured to support custom link speeds of up to 65 Gbps . This enhancement enables improved flexibility and throughput for high-performance w...

Key New vSAN Features in VMware Cloud Foundation (VCF 9.0)

The release of VMware Cloud Foundation (VCF 9.0) brings one of the most significant evolutions in vSAN to date—delivering performance, efficiency, and flexibility enhancements tailored for today’s demanding workloads. With data growth accelerating and enterprises embracing AI, analytics, and hybrid cloud strategies, storage platforms must do more than just store bits—they must accelerate innovation, protect critical assets, and optimize resource usage. In VCF 9, vSAN introduces breakthrough capabilities like  cluster-wide global deduplication ,  native vSAN-to-vSAN replication with deep , immutable snapshots , and major data path performance optimizations . Combined with ESA’s blistering IOPS performance, advanced memory tiering, and greater storage architecture flexibility, these features address modern enterprise needs ranging from AI/ML pipelines to cyber-resilient disaster recovery. In this article, we’ll explore the most im...
