DevOps Engineer at a consultancy with 11-50 employees
Hardened, fast-launching base image that streamlined our Kubernetes node deployments
More published documentation around the exact CIS controls applied and how to layer additional Kubernetes-specific hardening, such as kubelet and CIS Kubernetes benchmark, on top would be helpful. A minimal or slim variant tuned specifically for container hosts and clearer release notes per version would also be welcome. Out-of-the-box monitoring and observability integration could be expanded.

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.

Quotes from Members

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

Pros

"Predictable, repeatable EC2 launches have lowered our operational overhead and increased our confidence when scaling node groups."
"The platform has improved system reliability, security, and operational consistency across our infrastructure."
"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."
"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."
"The speed and efficiency of PubNub, which helps transfer data in real-time with very low latency, received positive feedback from our customers."
"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%."
 

Cons

"More published documentation around the exact CIS controls applied and how to layer additional Kubernetes-specific hardening on top would be helpful."
"The initial setup and configuration process can be complex for teams without prior Red Hat experience."
"Since PubNub is a paid library, it may not be useful for everyone."
"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."
"Regarding customer support from PubNub, around six years ago, we did not receive good support."
"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 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."
