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.

Containerization with automation has improved deployment speed and supports efficient DevOps work

One area for improvement would be longer security support and more frequent updates. Ubuntu 18.04 (Ubuntu 18.04 LTS) | Support by SupportedImages is stable, but as technology evolves, compatibility with newer versions of Docker, Kubernetes, and other DevOps tools can become a challenge. I would also want to see more lightweight and optimized official Docker images to reduce image size, improve build times, and minimize security vulnerabilities. Better documentation and smoother dependency management could also be more helpful. I would like Canonical to focus more on security updates, vulnerability scanning, and compatibility with modern DevOps tools. For example, smaller or more optimized Docker images would help reduce build time and improve container startup performance. It would also be helpful to have regular updates for commonly used packages and better compatibility with newer Docker and Kubernetes versions. Another important area is clear documentation for upgrading older Ubuntu versions to newer LTS releases without disrupting existing applications. These improvements would make Ubuntu 18.04 (Ubuntu 18.04 LTS) | Support by SupportedImages more secure, efficient, and easier to maintain in production. The main areas of improvement that kept my rating at eight instead of a nine or ten would be that there are some newer technologies and dependencies that might have compatibility issues with older packages. Additionally, security maintenance and upgrading to newer LTS versions require additional effort. Overall, it is a good platform, but there is room for improvement in modern tool compatibility, security, and container optimization. A small improvement would be better built-in monitoring and diagnostic tools, making it easier to identify performance issues, memory usage, and resource bottlenecks. It would also be helpful to have similar security patch management, clear upgrade notifications, and more detailed documentation for Docker and Kubernetes compatibility. These small improvements could significantly ease day-to-day system administration and reduce troubleshooting efforts.

Pros

"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."

"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."

"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 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%."

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

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

"What I like about the product is the license cost and security, as there is no license cost for Ubuntu 18.04 (Ubuntu 18.04 LTS) | Support by SupportedImages."

"Ubuntu 18.04 (Ubuntu 18.04 LTS) | Support by SupportedImages provides a reliable and flexible environment for our day-to-day activities."

Cons

"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."

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

"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 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."

"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."

"The main areas of improvement that kept my rating at eight instead of a nine or ten would be that there are some newer technologies and dependencies that might have compatibility issues with older packages."

"Using open-source, Excel-based tools is not very user-friendly."
