Why Choose vRealize Automation (vRA) over Ansible

Ansible and vRealize Automation (vRA) are both popular DevOps tools for infrastructure automation and provisioning. However, the two tools have different strengths and use cases, and choosing the right one for your organization can be a challenge. In this blog post, we’ll explore the key differences between vRA and Ansible and why you might choose vRA over Ansible.

  1. Complexity of Deployment

Ansible is a simple, agentless tool that is easy to install and configure. However, as the complexity of your deployment increases, the simplicity of Ansible can quickly become a hindrance. vRA, on the other hand, is a complex tool that is designed to handle complex deployments, making it an ideal choice for large, complex environments.

  1. Integration with Other Tools

vRA integrates with a wide range of tools, including vSphere, NSX, and vRealize Operations, allowing you to manage and automate the entire software-defined data center. Ansible, on the other hand, does not have this level of integration, which can lead to a more fragmented environment.

  1. User Interfaces

vRA has a rich, web-based interface that allows you to easily manage and automate your infrastructure. The interface is intuitive and easy to use, even for those with limited technical skills. Ansible, on the other hand, is a command-line tool, making it more difficult for non-technical users to use.

  1. Scalability

vRA is designed to scale as your organization grows, allowing you to manage an increasing number of servers and applications. Ansible, while scalable, is not designed to handle the same level of scale as vRA, making it a less ideal choice for large enterprises.

  1. Cost

Ansible is open source, which means that it is free to use. vRA, on the other hand, is a commercial product that requires a license. While the cost of vRA may be a concern, the additional features and capabilities offered by vRA can make it a better choice for organizations that need a more robust automation solution.

In conclusion, while both Ansible and vRealize Automation have their strengths, vRA is a more powerful and scalable solution that is ideal for large, complex environments. The integration with other tools, rich web-based interface, and scalability make vRA a better choice for organizations that need a robust infrastructure automation solution.

Why Choose VMware vRealize Automation Over Puppet

When it comes to managing large, complex IT infrastructure, two of the most popular tools are VMware vRealize Automation (vRA) and Puppet. Both tools have their strengths and weaknesses, but in this article, we will examine why you might choose vRealize Automation over Puppet.

  1. Integrated Management: vRA integrates with VMware’s vSphere virtualization platform, allowing for a seamless management of virtual machines (VMs). With Puppet, you would need to use additional tools to manage your virtual environment.
  2. Cloud Management: vRA is capable of managing both on-premise and cloud infrastructure, making it an ideal solution for hybrid cloud environments. Puppet, on the other hand, is primarily focused on on-premise deployments.
  3. Automation: Automation is at the core of both vRA and Puppet. However, vRA provides a more comprehensive automation solution with its built-in workflows and drag-and-drop design. This makes it easier for users to automate their infrastructure without having to write complex code.
  4. Self-Service: vRA provides a self-service portal for users to request and manage their own resources, reducing the burden on IT. Puppet does not have this capability, making it a less attractive option for organizations looking to implement a self-service model.
  5. Cost: vRA is a commercial product and is typically more expensive than Puppet. However, the added features and integration with other VMware products make it a more cost-effective solution in the long run.

In conclusion, if you are looking for a comprehensive and integrated management solution that covers both on-premise and cloud environments, then vRealize Automation is the way to go. It provides a more user-friendly automation solution, with a self-service portal, making it easier for users to manage their infrastructure. However, if you are on a tight budget and have a primarily on-premise deployment, Puppet might be a better fit for your organization.

Why Choose VMware vRealize Automation (vRA) over Terraform

In the world of infrastructure as code (IAC), there are many tools to choose from. Two popular options are VMware vRealize Automation (vRA) and Terraform. While both have their strengths, there are compelling reasons to choose vRA over Terraform.

  1. End-to-End Automation: vRA automates the entire software-defined data center (SDDC) lifecycle, from provisioning to decommissioning. Terraform is more limited, focusing only on infrastructure provisioning.
  2. User Experience: vRA provides a user-friendly interface, making it easier for non-technical users to request and manage infrastructure. Terraform, on the other hand, requires more technical expertise to use effectively.
  3. Integration with VMware: vRA integrates with other VMware products, such as vSphere, NSX, and vSAN, allowing for a seamless experience. Terraform can also integrate with VMware, but it requires more manual effort to set up the integration.
  4. Enterprise-Grade Security: vRA includes enterprise-grade security features, such as role-based access control and multi-factor authentication. Terraform does not have built-in security features, requiring additional tools or manual effort to secure the environment.
  5. Robust Compliance Features: vRA includes compliance features, such as blueprints that enforce specific policies and standards, making it easier to meet regulatory requirements. Terraform does not have built-in compliance features, leaving it up to the user to ensure compliance.
  6. Strong Support: vRA has a large, global community of users and is backed by VMware, a well-established company in the tech industry. Terraform is a relatively new tool with a smaller community, making support and resources more limited.

In conclusion, vRA offers a complete automation solution for the SDDC, making it a great choice for enterprises that want a user-friendly interface, strong security features, robust compliance features, and strong support. Terraform, while a powerful tool, is better suited for infrastructure provisioning and requires more technical expertise and manual effort to secure and ensure compliance.

vROPs tagging and workload optimization

Optimizing workloads in a custom datacenter with multiple clusters is a challenging task that requires a comprehensive understanding of the underlying infrastructure and the applications running on it. One of the key components of this optimization process is proper tagging using vRealize Operations Manager (vROPs).

Tagging in vROPs is a process of assigning metadata to objects such as virtual machines, hosts, and clusters. This metadata provides context to the objects and helps to categorize them based on their characteristics, making it easier to manage and monitor the infrastructure.

In the context of workload optimization across a custom datacenter with multiple clusters, vROPs tagging plays a critical role in several ways:

  1. Resource Utilization: By tagging objects with relevant metadata, vROPs can provide real-time visibility into the resource utilization of each cluster, allowing administrators to identify over-utilized or under-utilized resources.
  2. Workload Placement: vROPs tagging can be used to determine the most appropriate cluster for a given workload based on its resource requirements and the available resources in each cluster. This helps to ensure that workloads are placed in the right environment to meet their performance and availability requirements.
  3. Capacity Planning: Tagging enables vROPs to gather data on resource utilization trends, which can be used to plan for future capacity needs. This information helps administrators to make informed decisions about resource allocation and identify areas where additional resources may be required.
  4. Compliance and Governance: By tagging objects with relevant metadata, vROPs can enforce compliance and governance policies. For example, administrators can use tags to ensure that sensitive data is stored on compliant clusters or that workloads are placed in clusters that meet specific security requirements.

In conclusion, vROPs tagging is an essential component of workload optimization across a custom datacenter with multiple clusters. It enables administrators to gather real-time visibility into the resource utilization of each cluster, make informed decisions about resource allocation, and enforce compliance and governance policies. By leveraging vROPs tagging, administrators can ensure that their infrastructure is running efficiently, effectively, and securely.

vROPs DRS requirements across multiple data centers

vSphere Resource Management with vRealize Operations (vROPs) DRS across multiple data centers is a critical requirement for managing large-scale virtualized environments. In this blog, we’ll discuss the requirements for using DRS in vROPs across multiple data centers.

  1. Cross vCenter vMotion (CVC-vMotion) Support: CVC-vMotion enables vMotion of virtual machines across multiple vCenter servers. This capability is a pre-requisite for vROPs DRS across multiple data centers.
  2. vCenter Server 6.7 Update 1 or later: vROPs DRS across multiple data centers requires vCenter Server 6.7 Update 1 or later. This ensures that the necessary APIs are available to enable vROPs to manage resources across multiple vCenter servers.
  3. Network Connectivity: All data centers should have a reliable and high-speed network connectivity, with the necessary firewall ports opened for communication between vCenter servers and vROPs instances.
  4. vROPs Replication: vROPs instances in different data centers must be able to communicate with each other. vROPs replication can be used to keep the data in all vROPs instances in sync, ensuring that the vROPs DRS decisions are based on consistent data.
  5. Same vROPs version: All vROPs instances must be running the same version of vROPs to ensure compatibility and prevent any issues with data consistency.
  6. Same vROPs license: All vROPs instances must be licensed with the same vROPs license, and the license should include the vROPs DRS capability.
  7. Cluster Configuration: The virtual machines that need to be managed by vROPs DRS must be in a vSphere cluster that spans across multiple vCenter servers. The vSphere cluster must be configured with the appropriate DRS settings, such as automated DRS, to ensure that vROPs DRS can make effective resource management decisions.

In conclusion, vROPs DRS across multiple data centers is a powerful tool for managing virtualized environments at scale. By following these requirements, organizations can ensure that their vROPs DRS implementation is effective, efficient, and reliable.

DRS Rules in vROPs and vCenter

The Distributed Resource Scheduler (DRS) is a key component of the vSphere platform, and is used to manage resource allocation and workload distribution within virtualized data centers. DRS works by analyzing resource utilization and workload demands of virtual machines (VMs) and making recommendations for placement and resource allocation based on a set of rules.

In the context of vRealize Operations Manager (vROps), DRS rules play an important role in ensuring optimal performance and utilization of virtualized resources. By using vROps, administrators can monitor resource utilization and workload demands in real-time, and make informed decisions about resource allocation based on this data.

There are several types of DRS rules that can be created and configured in vROps, including:

  1. Affinity rules: These rules define the relationships between VMs and specify whether they should run on the same host, or whether they should run on separate hosts. This allows administrators to control the placement of VMs to ensure optimal performance.
  2. Anti-affinity rules: These rules define the relationships between VMs and specify that they should not run on the same host. This helps to ensure that VMs are isolated from each other, and helps to prevent resource contention.
  3. Shares and limits: These rules define the amount of resources (such as CPU, memory, and storage) that should be allocated to each VM. This allows administrators to control resource utilization and ensure that VMs are not over-allocated.
  4. Automation levels: DRS can be configured to operate in either fully-automated or partially-automated mode. In fully-automated mode, DRS makes all placement and resource allocation decisions, while in partially-automated mode, administrators can specify the rules and policies that should be used.

In vCenter, administrators can manage and configure DRS rules through the vCenter Server interface. The vCenter interface provides a graphical interface for creating, editing, and deleting DRS rules, and allows administrators to monitor resource utilization and workload demands in real-time.

In conclusion, the Distributed Resource Scheduler (DRS) rules play a critical role in ensuring optimal performance and utilization of virtualized resources in vSphere environments. By using vROps and vCenter, administrators can monitor resource utilization, configure rules, and make informed decisions about resource allocation to ensure that virtualized resources are used effectively and efficiently.

Enabling Basic authentication in VMware Orchestrator

VMware Orchestrator is a powerful automation platform for administrators. In order to secure the access to the Orchestrator, it is recommended to use Single Sign-On (SSO) authentication. However, there may be instances where SSO is not available and you need to use basic authentication instead (ex: Aria Operations plugin). In this case, you can set the value of com.vmware.o11n.sso.basic-authentication.enabled property to true.

Here are the steps to set com.vmware.o11n.sso.basic-authentication.enabled value in VMware Orchestrator:

  • Access the vRealize Orchestrator configuration interface at https://your_orchestrator_FQDN/vco-controlcenter or https://your_vra_FQDN/vco-controlcenter with the vRA appliance root credentials. This can be done through the vRealize Orchestrator Client by going to “Administration” > “System Properties”.
  • In the “System Properties” section, click on “New”.
  • In the “Property name” field, type “com.vmware.o11n.sso.basic-authentication.enabled”.
  • Change the value to “true”.
  • Click on “Add”.
  • The services vRealize Orchestrator service should automatically restart for the change to affect.
  • Verify that authentication now works

By setting the com.vmware.o11n.sso.basic-authentication.enabled property to true, you can use basic authentication instead of SSO for accessing the VMware Orchestrator. This can be useful when SSO is not available or when you need to use a different authentication mechanism.

Note: If you are using a load balancer for vRealize Orchestrator, you need to set the property on all the vRealize Orchestrator nodes in the cluster.

In conclusion, setting com.vmware.o11n.sso.basic-authentication.enabled value in VMware Orchestrator is a simple process and can be done through the vRealize Orchestrator configuration interface. Just follow the steps outlined in this article and you’ll be up and running in no time!

SDDC SaltStack Modules – vRA edition

In this blog post I will go over the steps I took in order to to be able to query my vRA components from SaltStack using the SDDC SaltStack Modules. The SDDC SaltStack Modules were introduced in 2011. You can find the technical release blog here. The modules can be found on GitHub here. There is also a getting quick start guide that can be found here. The vRA module which needs to be installed manually can be found here.

The first step was to create the /srv/salt/_modules folder as it does not exist by default

mkdir -p /srv/salt/_modules

If you don’t have git installed it can be easily installed by running:

yum install -y git

This will also install the dependencies:

Once completed we can run the below to clone the repo. Make sure you are in the /srv/salt/_modules directory

git clone https://github.com/VMwareCMBUTMM/salt_module_for_vra.git

As per documentation the python script should be in /srv/salt/_modules/ however with the git clone it actually created a subdirectory. To fix it i ran:

mv /srv/salt/_modules/salt_module_for_vra/* /srv/salt/_modules/

Now that i had the module in the proper location, I had to let salt know by running a sync

salt-call saltutil.sync_modules

or to sync it across all minions

salt '*' saltutil.sync_modules

Looking at the api documentation found here i picked on getting detail for my vsphere cloud account using the get_ca_by_name function. For the purposes of my test i did a salt-call. Per the documentation we need to include the function, username, password and account. It looked like this in my environment:

salt-call vra.get_ca_by_name vra-01a.corp.local administrator password vcsa-01a

Next i wanted to see if i can create a cloud account. Based on the API reference i can use the create_vsphere_ca followed by vra_url, username, password, vcenter anme, vcenter username, vcenter password, name i want for the account, region to add from vcenter. It looked like this in my environment:

salt-call vra.create_vsphere_ca vra-01a.corp.local administrator password vcsa-01a.corp.local [email protected] password vcsa-01a Datacenter:datacenter-3

Once ran, i was able to verify in vRA that the account was created

As a remidner the API documentation can be found here

And the module can be downloaded from here

Next i would recommend looking at the example i have for vSphere found here
