Red Hat OpenStack Platformの評判・口コミ 全6件

What do you dislike?

It can be complicated and involve to many modules. Knowing OpenStack is open sourced some features work better than others.

What do you like best?

The community really responds to new feature requests and the platform itself has taken a huge leap forward. If you are familiar with Linux and virtualization technologies OpenStack will be a breeze.

Try it, you will love it.

What do you dislike?

At first version it has some crashes mostly nova-compute , but in recent version lots of bugs have solved, but I think its UI can be designed better.

What do you like best?

First, it is a open source software which is great, over time it is adding lots of big features like database as service or it network management. it has a great support for different hypervisor and it's networking after nova is really good I can help to meet lots of requirement in a real scenario.

If you want to start a private or public cloud, openstack is the best open source and free solution you will find

What do you dislike?

I reckon that OpenStack may be a difficult to start with (I'm talking about production ready deployment, not a development one). It's modular architecture is flexible but it may be difficult to find out what is going on. For instance, you have to repeat configuration across components, keep them in sync. Besides, OpenStack touches some advanced technologies such as network or compute virtualization so it requires a vast knowledge to setup and maintain it.

What do you like best?

What I value the most at OpenStack is the OpenSource community support that comes up in many ways. Firstly, it easy to find an OpenStack installation designated for platform of your choice (we used RDO for a RedHat installation). Secondly, there is a thriving discussion list were you can easily find help about almost everything. Lastly, there is a wide variety of plugins, thrid part projects that may potentially help meeting your business goals. For instance, we used Sahara to easily deploy Hadoop clusters. Thus, we didn't need to focus at all at cluster provisioning - we used use already existing tools which is great about OpenStack.

It is clearly a leading OpenSource IaaS platform (just take a look at its community and supporting companies). However, it requires an expertise in advanced topic (virtualization in its all aspects: compute, network, storage). Hence, it may be a difficult to start with but it certainly pays off.

What do you dislike?

Nothing. I prefer it to a lot of other services.

What do you like best?

We deployed on our own server. Very easy to monitor and apply security and limit pool of users.

What do you dislike?

Setup is very painful, and if you don't need all the features it's hard to trim down the documentation to find your way through it based on your needs.

What do you like best?

The fact that it uses readily-available low-level tools, it makes easier to work with it

Recommendations to others considering the product

Be sure you understand the cost-benefit tradeoffs, as it's not that easy to setup and it requires a lot of time for maintenance. Consider if you really need all the flexibility it provides. Take into account some time to figure out which subset of features you need.

What do you dislike?

It will be much better if openstack can support monitoring service, or provide some advice about how to monitor openstack service. We now still spend a lot of time in openstack maintenance.

What do you like best?

I like openstack framework and its ecosystem. There a lot of drivers in community, and user can also implement a new one for different vendor. I come from a public cloud computing company in China. We implement different drivers for openstack to let it can manage our own network, virtualization and storage environment.

What do you dislike?

Docs are far from ideal, in quantity and quality, OpenStack is huge and things change way to fast and thus sometimes documentation doesn't help you to explore the latest or best of OpenStack.

To deploy openstack isn't a easy task, every single project has a ton of options, and of course it's hard to keep puppet/chef/ansible/some-other-tool sync'ed with the volume of new features every release.

What do you like best?

First of all, Openness: It's a free and open source project, if it doesn't contain that awesome feature you wish so much, you have the opportunity to contribute to get it on the project. The community behind it is composed mostly by developers of the hundred cloud companies that support and make use of the project. That means a huge base of users under several vendor's cloud around the world, bringing some reliability to the project. The community cares about avoiding vendor lock-in and thus there are initiatives to assure vendor's openstack cloud compatibility with OpenStack's.

Also, quality assurance (QA) *really* matters in OpenStack. You'll see unit, functional and integration tests, besides a rigorous code review process on every change proposed for every project. Of course it's not bug free, nothing is IMHO but I feel like its community is a huge example of how QA should be done.

It's an abstraction layer to manage all the different services necessary to get a cloud environment up and running, thus you can chose which hypervisor, storage and network kind you want to use (which means that your knowledge on your current infrastructure will be useful using OpenStack as well).

Finally the fast growing ecosystem around it, thanks to the big tent initiative, will provide most of all the services and tooling you may need to deploy or offer a robust cloud environment.

Recommendations to others considering the product

So several people I talk to think OpenStack may be the solution of their problems. You need to evaluate cautiously if that is *really* the correct solution. Maybe you just want to manage your guests, or containers locally, in which case OpenStack isn't the better choice (the overhead installing and maintaining it will not be worthy). OpenStack is something aiming to offer enterprise class set of services integrated and well tested, so sometimes it will be overkill to some smaller tasks, you need to consider the trade off.

What do you dislike?

From my point of view OpenStack is not something easy to use.

It doesn't provide smoothly user experience, very often something doesn't work as expected.

I can say that OpenStack is a framework for creation your own cloud, but it is not ready-to-use cloud platform.

A lot of companies like Mirantis, HPE, Red Hat are trying to sell their own "ready-to-use" distributive of OpenStack.

And I feel that it is a really big problem, because big players are trying to create it's own proprietary version of openstack and don't place all changes back to the community.

Big players wants to get a lot of profit from the project with minimum efforts on improving OpenStack.

Just try it and you will see that usability of OpenStack is really bellow any expectations.

What do you like best?

OpenStack is truly opensource project and everyone can use it or change whatever he wants.

For developers it means that you always can know what is under the hood.

For companies it means possibility to try OpenStack or use it without expenses on licenses.

OpenStack has modular architecture that allows you to select a set of services that you need or create and integrate your own service (For example your own billing or integration with services of your company).

OpenStack is fast-paced project that evolve continuously, every new release brings new services and new features.

I like the community behind OpenStack. If you want to be OpenStack contributor, it is really easy.

Recommendations to others considering the product

It is easy to try. You can try it online. http://trystack.openstack.org/

It has pros and cons, so everyone should decide himself.

What do you dislike?

Complicated setup and steep learning curve.

What do you like best?

Open Sourced, collaborative movement with great knowledge sharing amongst peers. The community helps each other a lot.
