Red Hat OpenStack Platformの評判・口コミ 全6件

What do you dislike?

I am still wondering if it is stable or not. Its official release is every 6 months. Even though it is a stable release, there are a bunch of bugs which are sometimes very critical to operate. For the commercial version, it should be released for more stable version.

One of the major problem is deployment. There are a bunch of solution for running OpenStack such as devstack, RDO, ubuntu, Midokura, Mirantis. In my case, I spent most of my time to install OpenStack instead of developing and operating some functions. It should be improved for the future.

Initially, OpenStack provided some virtual machines, storage, and very basic networking functions. As growing new requirements and functions, it is currently providing a bunch of new services for all kinds of cloud resources such as computing, storage, networking, policy, etc.

Because it is an opensource-based project, evolution and development are very fast and adaptive for new requirements. This is one of the best solution for any IaaS, PaaS, and XaaS systems.

OpenStack communities are very huge and all review processes are very instant. It is very easy to contribute our own code to the upstream. In addition, there are many customizable products based on OpenStack and we can easily deploy and test it.

Recommendations to others considering the product

OpenStack is a very good solution for providing public and private cloud. Even though there are many services for providing cloud resources, we can customize for our own purpose.

What do you dislike?

The architecture is still a little rough and the documentation needs work. One issue is how the setup of MySql and RabbitMQ is not properly clustered for maximum performance and stability. Setting up OpenStack without a commercial vendor is a bit rough and requires trying things a few times. The documentation is definitely lacking.

What do you like best?

The main benefit of OpenStack that I like the best is to not be tied to one vendor or another. Being able to switch vendors is very important. The pricing of OpenStack and the open source nature is extremely important as well. It is also wide spread so you can use it at hundreds of companies from small shops to online hosting to media companies.Using OpenOpenStack as a platform

Recommendations to others considering the product

Make sure you try it on a demo system and try to install it. Don't assume it will be easy to use. It takes some practice and work to use it.

Take a class, attend some meetups, make sure you know what you are getting into.

What do you dislike?

With all open source projects, there is a certain level of completion that may or may not exist in certain components. Most components of OpenStack are at a stable enough version to deploy confidently to a large user base, however there are a few (Ironic, for example) which are still heavily under development and not ready for use in the real world. In the same vain of open source projects, OpenStack is not a bugless system. We have encountered bugs with even well developed components. However, the ability to be able to propose patches and fix bugs that we discover in the process is something we actually do enjoy.

What do you like best?

In many ways the community is the best feature of OpenStack. With internal and remote cloud infrastructure solutions becoming more necessary for businesses moving to the cloud, the demand for IaaS providers and in-house cloud professionals is growing rapidly. The OpenStack community allows you to stay at the forefront of what is considered the industry standard for cloud compute technology, operations, infrastructure insights, and requirements.

Recommendations to others considering the product

Give it a try, the community is worth the effort.

What do you dislike?

It seems like it's a little _too_ generic and framework based. You can configure it however you want within the framework which can be a little overwhelming. Sometimes the framework can be a bit limiting.

What do you like best?

It's open source, and built with python. It's the best open-source alternative to AWS.

What do you dislike?

The project has tons of bugs that are waited to be resolved.

What do you like best?

Its vision to integrate many kinds of services is great. And being a open source project against Amazon AWS, is the main reason that I love it. Also, I'm a Python enthusiast!

Recommendations to others considering the product

Please be familiar with command line tools.

What do you dislike?

It requires a reasonably high level of expertise to setup and operate.

What do you like best?

OpenStack sets a standard for open source cloud, and is the most accepted and supported solution for those who don't want to be subject to vendor lock in, or pay licence fees.

What do you dislike?

OpenStack still has some issues with large cluster (more than 2000 servers in our case), and we are still struggling to solve the issue.

What do you like best?

We are using OpenStack to build a private cloud for our developers to build web applications. So far OpenStack works mostly great and saved us a lot of time! Specially, OpenStack provided a set of powerful CLI tools for administration, and a set of API for us to build an easy-to-use web interface to suit our need, and it runs quite stable.

Recommendations to others considering the product

Very easy to use and administrate Open Source cloud infrastructure. Recommended for private cloud in enterprise, however there are still some pitfalls.

What do you dislike?

I think, its so hard to install, some features isn't stable for example Horizon's function isn't complete.

What do you like best?

its provides perfect solution for cloud service and have good learning materials and active community
