Real-time chat has boosted one-to-one messaging and user engagement in my mobile projects

The best features PubNub offers, in my opinion, are one-to-one chat, as I mentioned in my review, and the great SDK documentation which allows for easy integration that does not take much time. Setting up channels, message listeners, tracking user status to determine whether users are online or offline, and ensuring reliable message delivery are all great features. I find myself relying on all three of those features the most because the presence tracking is great, the delivery speed is superb compared to other SDKs, and the user status updates immediately pop up, which is significant. The integration is very easy, so any new developers can easily understand the integration process thanks to the clear documentation. PubNub has positively impacted my organization as I have received numerous reviews and feedback stating that the chat works much faster and cleaner, and everyone appreciates it, saying it feels powerful. After implementing PubNub, I noticed positive outcomes such as client feedback acknowledging that they enjoyed the chat features and found them much faster than in other applications, which I believe is very positive feedback for any organization.

Pros

"What I appreciate most about Docker on CentOS 10 (x86_64 Docker) is that it is very lightweight, and its installation setup is quite easy, and in terms of stability, I find it amazing, with very low downtime compared to other container management systems and virtual machines, and it is user-friendly."

"Security features in Docker on CentOS 10 (x86_64 Docker) are very useful in protecting the containers and the particular images and host resources."

"Docker on CentOS 10 (x86_64 Docker) positively impacts my organization by enabling us to scale up and deliver faster deployments across environments."

"Docker on CentOS 10 (x86_64 Docker) has positively impacted my organization because it enables me to test applications much more easily and provides an isolated environment with all dependencies installed, which has accelerated my development workflow."

"PubNub has positively impacted my organization by reducing implementation time and developers' work, making it very easy to implement and enabling fast development that has reduced the developers' time by 40-50%."

"If we had implemented all of this on our own, we would have had to hire at least 50 more employees for that, so we are very happy with PubNub and we have saved a lot of time."

"PubNub's push notification and chat features stand out because of ease of use and very easy integration within our application."

"PubNub saves development time because we do not have to create a complete chat backend and frontend from scratch, enabling a plug-and-play approach that saves time, effort, and money for the company."

"The speed and efficiency of PubNub, which helps transfer data in real-time with very low latency, received positive feedback from our customers."

"PubNub has positively impacted my organization as I have received numerous reviews and feedback stating that the chat works much faster and cleaner, and everyone appreciates it, saying it feels powerful."

Cons

"Security scanning and OS patching need improvement because we rely on base images and do not have sufficient time to investigate them while moving quickly through our processes."

"I have observed a few things that can be improved. We need to optimize the image size and the build time."

"One thing I dislike about Docker on CentOS 10 (x86_64 Docker) is that sometimes if Kubernetes crashes, the basic understanding of Docker on CentOS 10 (x86_64 Docker) becomes tricky for new personnel, and I think the documentation is insufficient; newcomers need it to be more sophisticated and more informative."

"Regarding customer support from PubNub, around six years ago, we did not receive good support."

"The reliability of PubNub is really good, but occasionally we face issues where users complain about messages or push notifications not being delivered within a short period of time, as it occasionally takes longer, which could be due to outages."

"I gave PubNub a rating of nine out of ten because of the many features discussed, but I deducted one point because the cost increases with scale."

"Most of the time there are some instances at the load peak hours or sometimes payload is missed by the application or SDK at the SDK level."

"I believe PubNub can improve in terms of pricing transparency, as I previously mentioned, since that is the only thing I think should be improved because for smaller projects or startups, estimating scaling costs can be challenging."

"Since PubNub is a paid library, it may not be useful for everyone."
