Kirtishil Patil - PeerSpot reviewer
Senior Frontend Developer at Globant
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.

Centralized logging has transformed infrastructure monitoring and supports proactive recovery
The best features that rsyslog server offers include the ability to filter, tag, and rewrite logs, with logs stored in databases and files, then forwarded to various destinations such as SIEM or files as needed. Of course, the client sends the logs. Out of those features, I find myself relying most heavily on the logging capabilities it pulls from everything that is connected to Unix or Linux boxes, allowing me to see any particular issues or errors that may be occurring. The logs are stored in files or databases and they can be forwarded to me, even emailed directly. rsyslog server has positively impacted my organization, particularly with disaster recovery logging, where alerts for failures allow me to see failover events and any replication issues, especially within managed healthcare environments. It can indeed be used for HIPAA, pulling data from the entire infrastructure including Unix and Linux servers, network devices, firewalls, and storage arrays. Regarding how rsyslog server has improved efficiency and compliance, it provides insight into what's happening within the infrastructure as a high-performance systems log daemon receiving logs from the entirety of the network through UDP and TCP, writing to files, databases, or SIEM systems. It's user-friendly for Unix and Linux admins or engineers because it's been familiar for so long, and it certainly is not outdated.

Quotes from Members

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

Pros

"The speed and efficiency of PubNub, which helps transfer data in real-time with very low latency, received positive feedback from our customers."
"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 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."
"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 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."
"Rsyslog server's AI capabilities depict it as a data pipeline feeding AI systems, working hand in hand with AI for anomaly detection, ops automation, and log analysis through the collected syslog data."
"The best feature rsyslog server offers is syslog recording, serving as the main and most important feature by recording syslogs and receiving them from TCP or UDP, other UDP servers, and forwarding those logs to even other servers, allowing for daily syslog handling in any direction, TCP, UDP, local, or remote."
"The easy configuration and quick monitoring of rsyslog server help me in my day-to-day work as it saves my time and makes my troubleshooting easier."
"These features make my day-to-day work easier and more efficient because whenever I find any failure or boot problems in a client machine, I can easily identify the issue."
"The impact of rsyslog server on my organization has been positive, making processes easier, faster, and more reliable, as before its integration with the firewall, we lacked insight into policies governing incoming and outgoing traffic."
 

Cons

"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."
"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."
"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."
"I have not seen a return on investment; it is just about functionality for me."
"Currently, I use rsyslog server, but I think some features could be improved by going through other SIEM tools or IBM tools."
