Featured Reviews

Bruno da Silva - PeerSpot reviewer
Senior Manager at Timestamp, SA
Have worked closely with the team to deploy streaming and transaction pipelines in a flexible cloud environment
The interface of Apache Kafka could be significantly better. I started working with Apache Kafka from its early days, and I have seen many improvements. The back office functionality could be enhanced. Scaling up continues to be a challenge, though it is much easier now than it was in the beginning.
Deepankar Bbhowmick - PeerSpot reviewer
Integration Architect at a tech services company with 11-50 employees
Messaging design has become visual and reliable and now supports fast microservice communication
The unique functions I appreciate about PubSub+ Platform are that it allows me to design my solution in a graphical manner, which is not available in many other products, and the design can also be pushed to the actual infrastructure layer, making it quite advantageous. Mesh technology is useful in scenarios where different geographies have to be connected, although such situations are not commonly found. It is beneficial but not a super-used feature of PubSub+ Platform. The event replay function is quite mature in PubSub+ Platform, allowing me to replay messages that are days in the past, which is a good feature. The main benefits PubSub+ Platform provides for the end-user include building a robust and scalable system with very low network latency, which improves the customer experience, whether using mobile phones or applications. This type of messaging framework is extremely important, and Solace is a very good product in that space. Nowadays, most applications are built using microservices technology, with small microservices interchanging messages via PubSub+ Platform. Without it, realizing a scalable system would not be possible; for example, one cannot have Netflix or similar services that require quick data transit and a good user experience, ensuring that data cannot be lost in transit. The analytics part of PubSub+ Platform is quite useful as it can connect with many analytical software tools, mainly for analysis of system logs, such as Splunk, DataDog, or Prometheus. It has the flexibility to connect with any of these and supports OpenTelemetry, which is not available in many other products, making traceability very easy. I can see how a message travels from a source system to the target system, end-to-end, along with what happens to that message along the path, making the analytics quite good.
