Red Hat OpenStack Platformの評判・口コミ 全6件

What do you dislike?

Since the OpenStack product is pretty big now (more than four million lines of code), there is a high learning curve in setting up Openstack services whether it is for development or for production

What do you like best?

First of all, since I am a passionate Python developer, I love that there is an open source implementation of cloud services in Python. Openstack encourages open source development and contributions including helping new developers getting on board. They have very detailed documentation, good bug tracking with good filtering options. They even provide an IRC channel so that developers and dev ops can ask questions about installiong an openstack service instance.

Recommendations to others considering the product

Definitely look into Openstack if you are looking into contributing to a large open source Python project and/or if you are interested in the field of cloud computing

What do you dislike?

Scale issues are still unaddressed for years. Doesn't scale well for large deployments, let aside public cloud grade. Lack of extensive interoperability with AWS API.

What do you like best?

Openstack has an extensive API for all it's core services like Compute, Storage and Networking. Being open source, and flexibly licensed, it allows customized deployment as well as functionality. Support for a lot of hardware and software backends, due to it's pluggable, modular architecture is another big plus.

Recommendations to others considering the product

Make sure to choose the right strategy to deploy OpenStack, it can be a pain if you're looking at anywhere greater than 50-100 servers. Deploying continuously from trunk needs a robust CI/CD ecosystem.

What do you dislike?

Code review system. I still have an open bug. I didn't manage to fix it in a reasonable time because of the CI systems.

What do you like best?

Nova's project structure and some of the architectural choices performed by maintainers.

The ability to keep the pieces of the biggest open-source project in the world.

What do you dislike?

Getting the whole cluster view setup is still bit difficult.

What do you like best?

Documentation about all the complex terms about cloud explained in details.

Recommendations to others considering the product

Please review the requirements for servers and try to understand the specification for each node or server which you want to have it running in openstack and then try to implement the same in openstack with dev setup and install your application on top it to test the corner cases. And finally start moving it to full openstack deployment.

What do you dislike?

Massive amount of dependencies and heavy installation process.

What do you like best?

Open source and quick learning curve. Massive community support.

What do you dislike?

A bit time consuming to integrate into existing development cycle. Training is needed to get started as soon as possible, but it still carries a lot from other services like it.

What I would like the most is the ability to better monitor usage of individual VM's. Also better control of number of instances per process would help a lot, but it's not something that is a huge roadblock.

What do you like best?

Easy horizontal scaling and fast deployment vs other solutions available. Also feels more polished when it comes to bigger scale.

Once I got started I started appreciating Keystone really soon. It's really a valuable tool.

I also integrated Horizon and Heat to go along our existing development 'platform'.

What do you dislike?

It can be difficult to setup without using a Linux distro that already has it built in.

What do you like best?

Once it's running and configured correctly it's pretty much bullet proof.

Recommendations to others considering the product

It is a good solution that may meet your needs.

What do you dislike?

It may be specific to our implementation, but cross-region load balancing as a service seems to require a cascading solution to join the different regions under a parent Openstack. If we could further abstract and unify our different regions that would be great. I also don't love the UI for Horizon but I mostly use the command line anyway.

Openstack's biggest weakness in my mind is its youth - its offerings and features are always playing catch-up with AWS. I will often find a feature I like from AWS is either planned or currently being developed in Openstack.

What do you like best?

I think a REST interface for monitoring and controlling my infrastructure. I love software defined networking and the ability to quickly experiment with possible configurations on a large and inter-regional scale. As a developer who's used to working with a separate infrastructure team, self-service is incredibly empowering. It means that I can not only write but deploy and monitor new products and features at any time with zero friction. It makes our team much more agile within the organization.

I also use Terraform (https://www.terraform.io/) - a Hashicorp tool for automating a lot of what I do in Openstack and I love how easy it is to create what I want.

Recommendations to others considering the product

Evaluate its features and offerings relative to AWS - the industry standard. Don't make assumptions that certain services or features will be included or exactly the same as what you may have seen in AWS.

What do you dislike?

UI part is not really ok at this moment, is very laggy and start time of instance is also long...

What do you like best?

OpenStack is very good platform to deploy SaaS infrastructure. I can use it to start developper workspace every morning and is scalable for new hire !
