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.

Linux servers have supported secure deployments and provide straightforward configuration
We use a couple of third-party apps in Linux servers, such as Twingate or Fireflys, or we redirect our traffic on London-based servers. We use Linux and other third-party applications for security purposes. User interface is an area where Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages could improve. Mac is famous for its user interface and seamless experience with other products. Similarly, Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages should provide a better UI/UX experience over the OS and better connectivity and better application support. Windows and Mac support a vast variety of applications, but Linux is lacking in this area. System configuration is something I would see added to Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages in the future. The App Store lacks many applications, so it could improve the application support.

Pros

"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."
"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."
"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%."
"The speed and efficiency of PubNub, which helps transfer data in real-time with very low latency, received positive feedback from our customers."
"When I think of the advantages of Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages, the very broad community support comes to my mind; most of the questions are very quickly and reliably answered, and that is in fact better than what we face with AlmaLinux, which is more of a niche type of operating system."
"The biggest advantage that I found in GitLab is that I have all the control of my code in house."
"Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages is a leader because it provides full architecture of servers, machines, and operating systems."
"Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages offers good security from the first minute of use and is better than Windows for me."
 

Cons

"Since PubNub is a paid library, it may not be useful for everyone."
"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."
"Regarding customer support from PubNub, around six years ago, we did not receive good support."
"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."
"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."
"User interface is an area where Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages could improve."
"Because of the community involvement, I mentioned that at some point I get stuck and need to rely on the community and either work out my own solutions."
"Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages is not my main operating system."
"Emphasizing improvements for Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages, I note that it is a bit bloated right now; it could be more lean with supported packages."
