Reliable, simple to manage, and offers great technical support

The support of VXLAN fits with our network management. Thanks to this we can propose mixed solutions using virtual resources on OpenNebula and bare metal servers hosted in our facilities linked to each other on the sale network. This use case is very useful when some applications need bare metal power (Kubernetes workers, huge databases, AI models computations, et cetera). The cluster management is very useful for splitting our different clusters (mutual vs dedicated). We can manage deployments and capacity planning without pain. The API is also really simple and it helped us to develop the Terraform provider to manage OpenNebula like any other cloud infrastructure.

The GitOps feature automatically picks up changes from my GitHub projects

There are a few areas for improvement. For instance, getting notification webhooks is not easy. In the free version, there's no straightforward way to be notified once a deployment is finished. Spacelift requires creating a notification policy, which involves using the open policies framework. However, this feature is not available on the free plan. Additionally, for each new project, I need to create a new IAM role, which is not optimal. It would be better if I could use a single role for all interactions with my AWS account.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It makes maintenance very easy and stress-free for our teams."

"I also like the ability to build custom functions. I can define a function where I have two types of views and configure the dependencies. The virtual data centers concept allows me to define users. If a user wants to join certain kinds of machines, the host and the other user won't see them. It gives me the flexibility to define multiple views and data centers in one place."

"The live migration feature has been great and is something we use very often."

"The ability to use it almost like a public cloud for an organization is a big asset, as it will create a value proposition and can control costs in a great way."

"It is quite easy to deploy."

"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."

"What's best about OpenNebula that people like is that it's easy to deploy. It's also easy to manage. It's interesting because people choose OpenNebula over other solutions because of the ease of management."

"OpenNebula is lightweight, stable, and easy to customize."

More OpenNebula pros

"One key feature is the Spacelift policies, which we can attach to deployments to ensure compliance with our standards."

"Knowing the HashiCorp Configuration Language (HCL) makes it easier to use without issues."

"I appreciate that I just have to connect to my AWS account with my credentials, and Spacelift handles the rest."

"Spacelift is like an extension of Terraform, where everything can be visibly managed."

"A valuable feature of Spacelift is that you can attach labels, and it is a modernized tool for infrastructure deployments. It is pull request-based, and you can see all the Terraform plan and apply logs on the pull request itself, which is not available across any other CI/CD tools."

Cons

"The protocol for clusterization is rough and doesn't work well."

"The storage feature that they have is a bit confusing."

"It should have a simple REST API like most other tools. It's the industry standard format. An XML-RPC API gives you an XML document that you have to convert and then do something with that. REST API endpoint provides outputs in a JSON document. I would also like to see support for user data or heat templates, which OpenStack offers, but OpenNebula doesn't have this yet."

"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."

"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."

"There are no payment gateways in OpenNebula."

"They have been saying for the past two and a half years that they would develop a feature to hot-add RAM and CPU, but it does not work."

"They should add more features like object storage."

More OpenNebula cons

"Spacelift currently lacks features that can help with complex type deployments and coordination for major deployments."

"Synchronization can be difficult when using older and newer versions with Kubernetes and HashiCorp."

"In the free version, there's no straightforward way to be notified once a deployment is finished."

"The self-hosted version does not have a lot of features compared to the SaaS version, such as cloud integrations for Azure and GCP."

"If you are a small enterprise organization, below 500 people, I would not recommend it."

Pricing and Cost Advice

"The licensing for OpenNebula used to be free, but now it's no longer free. A customer contacted me asking to move to another provider because of the changes in the licensing terms for OpenNebula. I have no information on how much the OpenNebula license is because the customer pays for it, and I only do the integration."

"The solution is open source so is free."

"VRA is very expensive but OpenNebula is free."

"We use the Community Edition, rather than the Enterprise Edition."

"OpenNebuoa has recently come up with a new subscription model that is economical and a lot of new customers are choosing this as it is an easy subscription model."

"OpenNebula gives good value for money."

"It is a bit expensive product."

Spacelift provides a sophisticated infrastructure management platform with key features such as Drift Detection and Terraform integration, simplifying complex deployments and enhancing user workflows through an intuitive interface.

Spacelift excels in modernizing infrastructure management by integrating smoothly with Terraform, using a pull request-based approach for visibility into logs. It automates change detection using GitOps from GitHub and supports AWS connectivity with credential management. Despite its strengths, some users find room for improvement in supporting smaller enterprises and offering more seamless cloud integrations with self-hosted versions. Handling of HashiCorp Vault secrets and cumbersome notification webhooks may require additional setup effort.

What are the most valuable features?

Drift Detection: Ensures user edits are managed effectively, reducing configuration discrepancies.
Terraform Integration: Seamless compatibility with Terraform for robust infrastructure management.
GitOps: Automates change detection from GitHub, ensuring efficient workflows.
Compliance Policies: Helps maintain infrastructure within regulatory guidelines.
Stack Execution: Enables runs with label attachments for organized operations.

What benefits or ROI can users expect?

Improved Deployment Control: Default plan prompts support structured and controlled deployments.
Streamlined Terraform Management: Enhanced visibility into logs aids in transparent and efficient operations.
Efficient AWS Interactions: Credential management simplifies connections, making operations more fluid.
Dynamic Infrastructure Handling: Supports significant projects by replacing tools like Terraform Enterprise.

In specific industries, Spacelift is primarily utilized for infrastructure management and deployment across platforms like AWS, Azure, and GCP. In banking architecture, it replaces Terraform Enterprise, ensuring secure and efficient operations. Projects like Google Fiber benefit from its capability to import and manage data effectively, engaging users with HashiCorp Language and GitHub for CI/CD integration.
