Design workflows have been transformed and now enable rapid ad visuals and campaign launches
Firefly offers several best features in my opinion. We have the TTS feature and TTV feature. Additionally, suppose I have a single image from the creative designer and I want to generate different variations or different sizes of that image that will get adapted mostly on Google Ads. For example, I want to generate different renditions of that same image in different resolutions. I can quickly go to Firefly and from a single image generate different multiple images in different renditions. Firefly also helps us expand images. For example, I have a small image that is a portrait and I want to convert that as a full image or a hero image, which fits on a wide screen. Firefly helps us generate the images. It will not be stretching or squeezing your image. Instead, Firefly takes the context from your image and generates the next object which could appear. For example, if I am standing on a beach, it will generate the beach. It will generate a few people, it will generate some pictures of the sea, maybe some coconut trees. Firefly has positively impacted my organization a lot. I can say it is helping us reduce the effort and cost, saving the cost. For example, I have to create one image for our social media post. For that, we have to request our creative team, and then a creative designer will work on that idea and take one day or two days to get the design complete. After that, it comes to the review. With the help of Firefly, we can quickly generate the images and get them reviewed. Our go-to-market becomes easy. Within two hours or three hours, we can complete this whole process: generation, review, and all, and go to the market instantly. Additionally, if we have one image available and I want to quickly launch a Google Ad campaign that requires different renditions of the image, I can quickly use Firefly and generate different renditions of the image using the single image. So, it also reduces the dependency which we had earlier with the creative designers and the creative team.

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.

Quotes from Members

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

Pros

"Firefly simply acts as a single source of truth for my cloud inventory and governance, and it complements my existing cloud and FinOps processes rather than replacing them."
"Firefly saves one employee, it saves 5 million annually, and we are currently improving 40% of our go-to-market time while reducing cost by 30% and increasing revenue by approximately 20%."
"It's easy to integrate OpenNebula with our IT systems."
"OpenNebula has very good integration with SAP Storage."
"For the entire data center, as a private cloud, I believe that user management, expert management, and the virtual data center is completely magic for the users."
"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."
"It makes maintenance very easy and stress-free for our teams."
"The most valuable feature of OpenNebula is that it scales very well."
"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."
"With a single click, we could set things up and initiate them."
 

Cons

"If I talk about the cost, the cost is a little high."
"However, I still see a lot of improvement scope in their service."
"Most of the competitors are offering some sort of billing software to transform their installation to work as a small-sized public cloud, but those offerings from OpenNebula are still missing."
"An area for improvement in OpenNebula is the number of features it has. The solution doesn't have that many cloud features compared to other solutions. You'd say, "Okay, simplicity over a rich feature list?" Some say, "No, I need a big machine or a cloud interface for my customers to manage resources. I don't have to go and do it for them." Some people do it that way, and it works, but I'd like to improve the limited features in OpenNebula."
"The storage feature that they have is a bit confusing."
"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."
"They should add more features like object storage."
"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."
"The web interface could be better. It's not very difficult to use, but there's room for enhancement."
"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."
 

Pricing and Cost Advice

Information not available
"We use the Community Edition, rather than the Enterprise Edition."
"VRA is very expensive but OpenNebula is free."
"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."
"The solution is open source so is free."
"OpenNebula gives good value for money."
"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."
