"Ansible is agentless. So, we don't need to set up any agent into the computer we are interacting with. The only prerequisite is that the host with which we are going to interact must have the Python interpreter installed on it. We can connect to a host and do our configuration by using Ansible."
"It has improved our organization through provisioning and security hardening. When we do get a new VM, we have been able to bring on a provisioned machine in less than a day. This morning alone, I provisioned two machines within an hour. I am talking about hardening, installing antivirus software on it, and creating user accounts because the Playbooks were predesigned. From the time we got the servers to the actual hand-off, it takes less than an hour. We are talking about having the servers actually authenticate Red Hat Satellites and run the yum updates. All of that can be done within an hour."
"Ansible provides great reliability when coupled with a versioning system (git). It helps providing predictability to the network by knowing exactly what's being pushed after validating it in production."
"Being a game-changer in configuration management software is what has made Ansible so popular and widespread. Much of IT is based on SSH direct connectivity with a need for running infrastructure in an agentless way, and that has been a big plus. SSH has become a great security standard for managing servers. The whole thing has really become an out-of-the-box solution for managing a Unix estate."
"One of the most valuable features is that Ansible is agentless. It does not have dependencies, other than Python, which is very generic in terms of dependencies for all systems and for any environment. Being agentless, Ansible is very convenient for everything."
"This is the most scalable product of its type."
"The most valuable features are ease of use and user interface."
"Over the last two years, they've enhanced a lot, especially in regard to integration with OpenStack."
"Overall, for me, it's a good solution and has been working well."
"Some of the key features I find most valuable are the highly graphical user interface, virtualization of networks, and Microsoft application compatibility. It has all the functionality that we require."
"The solution is easy to use and is good for management control."
"I have found the system to be very intuitive, functional, and they have great technology."
"The most valuable features are stability and low cost."
"Accessibility. Ansible uses a CLI by default. Those accustomed to it can find their way and adopt the YAML files easily over time. But, some users are more comfortable using UIs..."
"When you set up Playbooks, I may have one version of the Playbook, but another member of the team may have a different vision, and we will not know which version is correct. We want to have one central repository for managing the different versions of Playbooks, so we can have better collaboration among team members. This is our use case for using Git version control."
"Some of the modules in Ansible could be a bit more mature. There is still a little room for further development. Some performance aspects could be improved, perhaps in the form of parallelism within Ansible."
"Ansible is great, but there are not many modules. You can do about 80% to 90% of things by using commands, but more modules should be added. We cannot do some of the things in Ansible. In Red Hat, we have the YUM package manager, and there are certain options that we can pass through YUM. To install the Docker Community Edition, I'll write the yum install docker-ce command, but because the Docker Community Edition is not compatible with RHEL 8, I will have to use the nobest option, such as yum install docker-ce --nobest. The nobest option installs the most stable version that can be installed on a particular system. In Ansible, the nobest option is not there. So, it needs some improvements in terms of options. There should be more options, keywords, and modules."
"The area which I feel can be improved is the custom modules. For example, there are something like 106 official modules available in the Ansible library. A year ago, that number was somewhere around 58. While Ansible is improving day by day, this can be improved more. For instance, when you need to configure in the cloud, you need to write up a module for that."
"Everybody needs a network to connect to, and VMware doesn't readily provide one."
"Occasionally the licensing is not very clear. They should make it easier to understand."
"Quite a complex solution."
"There could be an improvement in regards to security."
"Traffic flow introspection topology visibility is definitely needed because at the moment, NSX-T lacks in this area."
"There are sometimes mismatch in the control, the details and what you actually see on the transport note."
"They need to enhance their technical support."
"The training costs a minimum of $3,000, which is expensive and should be reduced."
