Has enabled flexible deployment of modular services with high availability and smooth dynamic updates

The best features of IBM Open Liberty are the implementation of MicroProfile and Jakarta EE, along with fault tolerance and high availability. It's easy to use and deploy new features. The profile is easy to configure and set up features. For example, using fault tolerance from MicroProfile or using servlets or JAX-RS allows for easy configuration and creation of modular applications. The configuration is modular. The main point for us in this project was high availability, high performance, and the implementation of MicroProfile and Jakarta EE. We utilized the modular architecture of IBM Open Liberty by creating different microservices using different environments. We created different configurations for different services using the configuration of IBM Open Liberty. This was very beneficial. We created different environments only by changing the configuration, depending on the functionality we needed. It was good and very flexible for us. I used the dynamic updates feature of IBM Open Liberty and different configurations in different services and servers, based on the functionality we provided for our clients. The flexibility to create different services in different environments using IBM Open Liberty was important. The high availability is guaranteed by the architecture of IBM Open Liberty, Java, and MicroProfile. The architecture guaranteed high availability, and the flexibility comes from being able to configure needed features. There's no need to load all WebSphere or functionalities in all environments. I can configure it and create a more highly available and scalable process. I implemented monitoring tools for IBM Open Liberty using Grafana and OpenTracing using the functionalities from MicroProfile and IBM Open Liberty. The monitoring tools helped with managing system performance.

Rapid prototypes have boosted development while long-term growth now needs clearer paths

My main use case for Nakama is the backend and matchmaking, and matchmaking is the most important aspect of Nakama for myself. The other real-time transport and parties and groups are built into that project, which is why I consider Nakama instead of writing my own backend and matchmaking. Matchmaking is by far Nakama's best feature. Matchmaking stands out for me because it is easy to deploy and get running, especially in contrast to Open Match, which requires a lot of work and setup to get things moving. Nakama provides this service in a simple manner, so I do not have to be a cloud engineer or backend engineer to set things up in order to have matchmaking. The real-time capabilities, parties, and groups of Nakama are straightforward and fast for various use cases, particularly if I am developing my own multiplayer game and need a transport layer. Instead of using raw TCP/IP sockets, I can use Nakama's sockets, which simplifies the process, making everything go in and out from the WebSocket.

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

Pros

"It is a stable solution compared to other vendors."

"The flexibility to create different services in different environments using IBM Open Liberty was important."

"Using Nakama has definitely helped my team save time and resources in measurable ways, such as faster development, particularly if we build multiplayer games according to their provided structure, although creating something with very custom features can be challenging."

"Nakama helps my team prototype and iterate faster, as instead of spending one to three months writing my own backend and matchmaking, I can start right away with Nakama, which represents a huge productivity gain at the start."

"In just a few hours, you can get a new game and a server with many features."

Cons

"Its support documentation could have detailed information on database integration."

"To improve IBM Open Liberty, more integration with Kafka and message systems, and asynchronous messaging would be beneficial."

"The biggest problem we had was that while it has some really nice features, dealing with the tournaments and leaderboards and how they are fixed and static makes the development process a bit of a hassle."

"The scalability of Nakama is not very good if using the open source version, as it lacks distributed presence features."

"Customer support for Nakama has not been that good based on my experience when we reached out to them."

Pricing and Cost Advice

"It is less costly than one of its competitors."
