Serverless workflows have boosted rapid AWS development but still need better CI and automation
Serverless has many advantages, and it is very easy to handle with a cloud solution. However, there are a few concerns about the limitations. Especially when I work with Lambdas, there are maximum Lambda timeouts. Likewise, there are several things from Serverless, such as maximum file uploads. Serverless can be improved by addressing the challenges faced when we have the first infrastructure. Sometimes it is hard because we need to manually create things such as Cognito pools. While 90 percent of the time is automated, more automation would be better. If Serverless provided CI/CD capabilities, that would also be great, as currently it only allows for manual deployments. Additionally, when working with cloud services, Serverless allows the use of LocalStack or Serverless Dev, but I think Serverless Dev might need simplification for easy access without organization registration. When considering needed improvements, I get frustrated with Lambda time and similar issues, which are actually not related to Serverless but rather are AWS issues. However, when discussing Serverless, the main points I see require improvement from the Serverless end.

Useful for creating build-outs and architecture views, but requires a publisher add-on for some detailed reports
I don't use the tool or know a lot. It is going to have some shortcomings. When it comes down to publishing, we just found out this week that they actually have a publisher add-on. So, what we were trying to publish was not giving a detailed report about the architecture, views, etc. I just wish they had sent these to UNICOM and contacted them about add-on features for the publishing part of the tool.

Quotes from Members

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

Pros

"Serverless positively impacts my organization by being really cost-effective and serving as a production performance testing tool, as we increase the load, it automatically increases the CPUs and RAM without needing any manual intervention or heavy servers for this type of testing."
"My advice to others looking into using Serverless is that you can use it if you want to save money, if you don't want to manage servers, if you only want to be charged for the amount of time you use, and if you want to run code and ad hoc tasks."
"Making use of Serverless has at least helped us save 50% in cost spending on resources."
"Previously, when we were deploying it on VPS, our whole day was spent on setting up a VPS and setting up all the CI/CD pipelines, but with Serverless it is instant and in just 10 to 15 minutes you are up and running."
"Serverless impacts my organization positively in many ways by enabling us to easily debug issues when any pipelines break; we can get errors, debug them, and address issues."
"I can share specific metrics indicating Serverless's positive impact: I achieved 100% uptime, an impressive feat compared to traditional servers that often experience downtime during peak usage."
"The best features that Serverless offers include being without the server, which itself says we don't need to depend on the server maintenance, and so we don't need to worry about these server things."
"Serverless has made my day-to-day work easier because we don't have to set up an extra team, and with fewer resources we can use it effectively."
"It has good end-to-end metamodel interrelationships."
"It is useful for creating build-outs and architecture views and for publishing reports and stuff like that for different programs."
 

Cons

"The biggest challenges I have faced while adopting or using Serverless include the different syntax, syntactical understanding, and the steep learning curve with team members."
"When that account was temporarily blocked for an unjustified reason on their side, it became an issue for our whole project and caused significant costs and loss of users because of that single incident."
"Transitioning from servers to Serverless results in a price increase due to the additional maintenance and patches AWS provides, but if costs could be reduced, more customers would consider moving to Serverless architecture."
"Serverless could be improved if we had more flexibility in how we use memory and could manage memory usage ourselves, especially for background tasks."
"Improving Serverless is a difficult question because I am not deeply familiar with Serverless, so it is really difficult for me to judge."
"Serverless can be improved by effectively handling large scale applications, as large scale applications would save more money."
"We have been using this framework for a long time but now feel the cost is expensive, so we need to improve in this area."
"The biggest area for improvement in Serverless is around cold start latency, especially for applications that aren't constantly active."
"They need to add reports that show the enterprise architecture perspectives, and the dashboards should be comfortable for the senior enterprise architects so that they can view the complete landscape."
"I don't use the tool or know a lot. It is going to have some shortcomings. When it comes down to publishing, we just found out this week that they actually have a publisher add-on. So, what we were trying to publish was not giving a detailed report about the architecture, views, etc. I just wish they had sent these to UNICOM and contacted them about add-on features for the publishing part of the tool."
"UNICOM System Architect is quite a dated tool. The usability needs to be improved."
 

Pricing and Cost Advice

"I don't remember the price. It is a different cost for just buying it, and then you have a maintenance cost, which you need to renew every year."
