"The Best Free Resource You can have it"

5/5

What do you like best about OpenStack?

I like that OpenStack gives you full control to build and manage your own cloud. It’s flexible, supports different hypervisors, and lets you scale resources as needed — all while being open-source. Great for learning and real-world cloud deployments. Review collected by and hosted on G2.com.

What do you dislike about OpenStack?

It’s quite complex and feels like a standalone ecosystem. It takes a lot of time to fully understand how everything works together, especially for newcomers. Review collected by and hosted on G2.com.

"Best tool for Hybrid Multi Cloud Infrastructure"

5/5

What do you like best about OpenStack?

You are in control of all the services and software, you can go to the root level of each service and modify it to your needs. We can use this to even create our cloud service platform over on-premise hardware. Moreover, it has a very useful visualization interface to get a clear picture of the infrastructure we build upon it. Review collected by and hosted on G2.com.

What do you dislike about OpenStack?

Few of the plugins or SDN need to be configured a lot and be even maintained timely. I would suggest using Ansible to manage those configurations as it will be automated then. Review collected by and hosted on G2.com.

Recommendations to others considering OpenStack:

If you have on-premise data centre and want to integrate those with the Cloud Providers for some deployment purposes, go for OpenStack Review collected by and hosted on G2.com.

What problems is OpenStack solving and how is that benefiting you?

It is helping us solve the purpose of on-premise datacentre integration with other cloud platforms like Azure, AWS, and GCP. We have a few Kubernetes clusters running on-premises hardware through OpenStack, and this gives us all the access to our data and services integrated seamlessly with Cloud Providers.

"Excellent top-down design architecture for on-prem cloud, complex, hard to get 5 nines reliability."

3.5/5

What do you like best about OpenStack?

Freely available on-prem cloud software orchestrator. Excellent top-down design with widest range of features (virtual networks, bare-metal support, container support, integrated VM and container support, vlan-aware VM support), etc. Review collected by and hosted on G2.com.

What do you dislike about OpenStack?

Complex architecture. Hard to get experienced personnel to support huge clouds and train new personnel. Stability not the best (hard to get five nines inspite of providing redundancy for most components and services). Review collected by and hosted on G2.com.

Recommendations to others considering OpenStack:

Free to use open-source software for implementing small, medium and large scale on-prem cloud infrastructures. Unlike VMware (which I consider a bottom-up design: started with hypervisor and then build the cloud orchestrator around it), Openstack is a well thought of top-down design architecture. Pros: Provides all the features one might ever think of using (currently) in today's cloud infrastructure. You will not find any feature lacking. Open source support is decent (developers and implementers genuinely try to help on the open source forums) but you get what you pay for. If you don't have the technical expertise and personnel to manage medium to large scale clouds it is advisable to sign up with professional services from some vendors. Cons: Hard to get experienced personnel and train new employees due to complexity. Stability is questionable. Impossible to get anywhere close to five nines in spite of having redundant nodes and services. Review collected by and hosted on G2.com.

What problems is OpenStack solving and how is that benefiting you?

"Good working tool."

4.5/5

What do you like best about OpenStack?

It has high formidable expectations which I like all the same in this private cloud system which offers rackspace through Openstack as the main service for its respective function in general, among these aspects is a fast uptime in the software For mobilized management, log to the simple platform for more efficient workflow, maintain capacity and performance analysis for the latest data on each customer. Review collected by and hosted on G2.com.

What do you dislike about OpenStack?

Does not have supervision of the company's digital supplies obtaining significant losses for this add-on that helps the beneficiary and not to the economic failure, the prices can be difficult to understand since it has various packages for its different accesses of functions for each client , thanks to its inconsistent interface that contains few tasks for user manipulation, especially when they are beginners. Review collected by and hosted on G2.com.

Recommendations to others considering OpenStack:

If you need a running application that does the custom settings for you quickly and automatically, the Openstack service software is available that is used by a very comprehensive formal operations management platform, making it highly recommended in massive terms including interesting features that you can exercise in your company, with a high-end range of ease and speed that the promulgated software acquires, having an analysis of productive performance. Review collected by and hosted on G2.com.

What problems is OpenStack solving and how is that benefiting you?

It is used in my company for its main functions offered by the software, which are resource management through a general panel computer on our digital servers, a storage of information necessary for a majority construction management of my company and Networks for operational advice analyzed to make them unique to your own use through a data center system that has the design of Openstack as a server in its extreme virtual privacy.

Its main advantage is that as it is an open source tool it is completely free, therefore it is an ideal tool for all organizations and therefore it would not affect their economic aspect. It is a very easy to use and highly scalable tool, therefore it is not necessary to have highly trained personnel to use it, its comfortable interface allows you to quickly adapt personnel. Review collected by and hosted on G2.com.

What do you dislike about OpenStack?

One of the most useful and frequent features of OpenStack is container management, therefore it should be a bit simpler and less complex because it is the most commonly used by users and it is complex to delay their work. Review collected by and hosted on G2.com.

Recommendations to others considering OpenStack:

I would recommend this open source tool since it is a cloud-based operating system that allows all companies, regardless of their size, to manage and calculate large groups of data storage, data center and network resources through a tablarero. Because it is an open source tool, small businesses would have no problem implementing them because it would not cause any change in the economic aspect. It prevents you from investing money and time in highly trained personnel to use it, it has a comfortable and easy interface that makes it easier for new users to handle themselves in an excellent way. Review collected by and hosted on G2.com.

It is a very productive tool that we implement in the organization in all departments, because through it we can communicate among the members of a team through the cloud, it is an open source tool that is simple and easy to understand and implement. At the same time we use it to control our resource accounting for product compliance. Thanks to OpenStack we have been able to execute a large number of projects from basic services such as the network to microservices.

"Decent software if you're prepared to do the learning."

4.5/5

What do you like best about OpenStack?

Openstack provides massive flexibility for deploying and managing virtual machines when combined with a GIT CI/CD pipeline it can massively reduce the time for each development cycle. Many other companies are using OpenStack due to the cost and so it is good to be using popular software that enables us to support customers better. The online documentation is great and very detailed. Review collected by and hosted on G2.com.

What do you dislike about OpenStack?

Openstack is quite complex and has a steep learning curve if you're prepared to invest the time it is great. Due to the nature of the software having in house experts is beneficial as many users struggle with some aspects and requiring everyone to be an expert incurs significant time costs. Having multiple users working on the same OpenStack deployment can create inter-team friction due to normal users being limited in what details they can view about the OpenStack deployment.
