Reduced manual work and built reliable real-time collaboration with serverless messaging

I love Ably for its advanced pub/sub messaging capabilities, which help us with messaging Delta Compression, allowing us to send only changes from previous messages instead of entire payloads every time. For example, if I have to say 'hi', instead of sending the whole payload, it only sends the change in the current payload, reducing bandwidth consumption and enabling high-frequency data streaming. This major change has made our clients really happy as they receive notifications and messages without latency. Additionally, if a client goes offline, Ably stores messages in history for up to 72 hours, allowing clients to query history and catch up on missed events, ensuring complete stream continuity. It also supports multi-protocol, using WebSockets and gracefully falling back to server-sent events and long polling as needed, including support for MQTT and IoT devices along with pub/sub control for easy migration.I appreciate the serverless integration that has the integrated native web hook, instantly triggering serverless functions such as AWS Lambda and Azure Function when specific real-time events occur. It also allows Kafka Connector for seamless ingestion of messages from Kafka topics to stream them out to millions of users in milliseconds.

Containerization has streamlined deployments and supports diverse monitoring and web workloads

I would rate Docker on Ubuntu 20.04 LTS a nine out of ten. I give it a nine because there is always room for improvement, so I would not give any product a perfect ten. Regarding Docker on Ubuntu 20.04 LTS's AI capabilities, I think its governance and security work quite well in terms of namespace isolation; the security is quite strong, but if you want something like image vulnerability scanning, it does not have anything built in, so you have to rely on third-party toolsets, and secret management is a bit of a downside. Docker on Ubuntu 20.04 LTS is pretty accurate regarding its AI capabilities and the accuracy and reliability of output. My advice to others looking into using Docker on Ubuntu 20.04 LTS is that if you are not using it, then try it. My overall review rating for Docker on Ubuntu 20.04 LTS is nine.

Quotes from Members

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

Pros

"Ably has a big capacity to stream data all over the world, has higher reliability and a 99.99% uptime, offers robust security guarantees and ease of integration, and saved at least 80% of the cost that would have required more developers and more time for integration testing and development."

"Ably has positively impacted our organization by providing a good return on investment by avoiding the labor cost of building and maintaining a custom WebSocket server."

"My most-liked feature is its highly reliable real-time messaging capacity."

"Ably has improved our organization by enhancing real-time communication capabilities and providing reliable data delivery."

"We experience vast improvements across many areas with Ably; when users connect bank accounts, we previously had to poll repeatedly, which is now replaced by Ably's real-time infrastructure that maintains a persistent back-end connection, significantly reducing the need for infrastructure management and API load, resulting in average bank connection display times decreasing from eight to twelve seconds down to one to two seconds, and with persistent back-end connections reducing API calls, we achieve a lower operational load, seeing an impressive reduction of thirty thousand to forty thousand calls monthly."

"Ably's API integration is intuitive; it definitely improved our efficiency, and we saw faster user interaction and around a 20% reduction in latency during peak times, which improved user experience as well."

"Docker on Ubuntu 20.04 LTS has positively impacted my organization as it provides a good way to run our toolsets and applications."

"For us it is a small tool; it is not a big investment, so we are not tracking the ROI of the product directly, but I can tell you that it gives a lot of useful features and overall the ROI is worth it."

"Docker provides comprehensive support for any deployment process, maintenance, or surveillance of any kind of project because it offers CLI and APIs, Docker Hub, and Docker Desktop client."

Cons

"Ably can be improved in several areas."

"It falls just short of a perfect ten only because full twenty-four-hour phone or live chat escalation is heavily gated behind their highest enterprise pricing tiers."

"Overall, Ably appears strong for managed real-time operations, but could improve areas such as pricing predictability."

"Docker on Ubuntu 20.04 LTS can be improved, particularly as security features can always be enhanced, and the configuration is somewhat fragmented with different configuration files that can sometimes be cumbersome."

"Connecting two containers to each other is very tricky and time-consuming for me as a developer."
