Cloud-based workflows have boosted team productivity but still need richer features and faster performance
AWS Cloud9 is powerful, but it can be improved in terms of performance, modern IDE features, limited updates, and dependency on AWS infrastructure, which sometimes slows productivity. Since it runs in the browser and depends on Amazon EC2 instances, performance can lag compared to local IDEs, especially for larger projects or lower specs instances. It also has limited modern IDE features compared to tools like Visual Studio Code, lacking a rich extension ecosystem, advanced UI customizations, and some modern developer productivity features. Improvements can include better performance optimization, a plugin ecosystem, faster startup times, and more frequent feature updates, as well as an improved collaboration experience. AWS Cloud9 is great for AWS native development but still lags behind modern IDEs in performance, flexibility, and the pace of innovation. In terms of improvements, richer extension ecosystems, faster startup, better performance for large projects, and triggering CI/CD pipeline integration would make the workflow much smoother. A stronger extension and customization capability would significantly enhance day-to-day work with AWS Cloud9. Offline or hybrid mode, including limited offline capabilities or local sync, would reduce the dependency on consistent internet connectivity. Better debugging and monitoring integration, with deeper integration into logging and monitoring tools like Amazon CloudWatch, would simplify troubleshooting without switching context. If AWS Cloud9 evolves with better performance, extensibility, and deeper DevOps integrations, it would become a much more complete modern development platform.

Good plugins and helpful templates with a useful auto-code suggestion feature
Eclipse's auto-code suggestion feature makes programming very easy and fast. Thanks to Eclipse, we can deliver fast and well-compiled code as it compiles the code on every hit which stops developers from writing bad code instantly. On top of this, we can integrate other software like Tomcat, and MySQL in Eclipse very easily which makes development even faster. Now, we can deploy our Java app directly into Tomcat from Eclipse itself which saves a lot of time in development. The same thing is true in MySQL. we can see data in Eclipse itself using SQL queries. There's no need to install a query browser application.

Quotes from Members

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

Pros

"AWS Cloud9 saves me two to three days per week in my work at Probus Insurance."
"Overall, AWS Cloud9 is a solid choice for working within the Amazon Web Services ecosystem, with its biggest strengths being zero setup, seamless AWS integration, scalability, and accessibility from anywhere, making development faster and more consistent."
"One thing I like the most about AWS Cloud9 is how easy it is to access different things and to look for what you are searching for."
"Some of the best features with AWS Cloud9 are that it is a cloud-based DE, so you do not have to have an IDE locally or set up the IDE every time when using different computers."
"Eclipse's auto-code suggestion feature makes programming very easy and fast."
"It is very extensible and uses resources optimally."
"It works like a one-stop shop for all of our application development requirements."
"Eclipse is a neat IDE; it works as a one-stop shop for all of our application development requirements, including development, debugging, unit testing, and an extensive list of plugins to extend functionality."
 

Cons

"Regarding the learning curve of AWS Cloud9, I would say for an average person, it will take at least three weeks to a month of consistently using it to finally get out of that learning curve."
"I would prefer to see changes in the pricing structure of AWS Cloud9 because it is too high."
"AWS Cloud9 is great for AWS native development but still lags behind modern IDEs in performance, flexibility, and the pace of innovation."
"AWS Cloud9 is being discontinued, so preventing its discontinuation would address the main pain point."
"I would expect the team to fix any existing bugs related to performance and make it more stable for future releases."
"I would like to see it extend native support for functional languages like Scala."
"Eclipse can sometimes be a plugin nightmare. Various plugins require different versions of the same plugin running for different reasons."
"I would give the technical support a rating of zero."
"The development of the product needs improvement."
