Rajaraman Ramachandran

Co Founder And CTO at Gamucopia Creatives

Has enabled us to manage compute resources efficiently while supporting multiple languages

AWS Lambda needs to improve cold start time. Some AWS Lambda functions require a cold start, and if you need AWS Lambda to provide quick responses, you need some of the AWS Lambdas to be always on, which is risky. We need AWS Lambda's cold start time to be reduced so that we can use it much faster than now. We need a better way to handle the cold start. We should be able to start AWS Lambda much before in a predictable way instead of just calling and then having it start.

A solution for data pipelines but has connector limitations

We have used Kafka for seven years. IBM streams gives you many OOTB features that can boost the time-to-market, especially when it comes to reporting and monitoring for example. Confluent is recognized as one of the leaders in this space and the main reason for this is related to the complete vision of the platform also the large number of connectors. This gives the edge and competitive advatnage.

Quotes from Members

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

Pros

"It's a serverless solution which is the best feature, it helps us because it offers free aspects, and from the infrastructure perspective, it helps us manage costs so there is no overhead of estimating how much infrastructure we're going to need and we can focus on building the business functionality that we want to build."

"The solution has improved our organization by providing us with better communication with the different services, dependencies, and implementations our clients require, and the solution is faster and the consumption is really good."

"The solution works for small applications. It is a serverless tool that is quick to spin up. We needn’t consider anything in the bag."

"With a highly variable load, our idle cost is pretty much zero, and we haven't had any scale barriers, so we've scaled smoothly."

"I have found all of the features valuable. It's an easy and cheap solution."

"We migrated from an on-premise server to the cloud with the Lamda solution and we found it less than one-10th of the cost of what it used to be."

"Lambda allows you to focus on the code itself."

"We don't have a problem with the stability of AWS Lambda; it's very stable."

More AWS Lambda pros

"The OEM Solution (Excel-medical.com) running on top of IBM Streams provides real-time clinical algorithms that can give better insight into the patient's acuity, thus cutting off time to discharge patients and inversely making sure that sick patients don't get discharged until ready."

"The product has enabled us to create solutions to client problems that would have either been impossible or very expensive/difficult using other technologies."

"Easy development and deployment, Java implementation features, and the real time analyser and alarm function are the most valuable features for us."

"As a result, the TELCO company was able to cut down the time it took to respond to customer needs and there were fewer complaints."

Cons

"The support team does not know how to implement and build the solution."

"The product needs some updating as far as ease-of-customization and configuration opportunities to work with solutions outside of the cloud."

"My concerns about monitoring in AWS Lambda are that the logs they provide are not easily understandable, and how they provide it makes it take time to find specific logs and that particular number itself."

"Having a better preview would be helpful."

"I wish to see better execution time in the next release."

"The reason for the eight rating is that sometimes when I want an event to occur, I want AWS Lambda to be called, but it is not calling at that particular time; it is calling after some time, which might be a latency issue that I am uncertain about, but in one project, I have seen this scenario."

"The execution time could be better. One of the major limitations is the time period because it doesn't give you more than seven minutes. So, before thinking about Lambda, you should think through your use case and ensure it's a good fit. Otherwise, you can use batch, step functions, or other methods. Reports and the monitoring board could also be improved in terms of alerts. The threshold alerts are there but can be improved. It takes some time to get used to these methods and get the hang of them."

"There are other similar solutions, such as Google Cloud Platform or Microsoft Azure. They might be better for small tasks."

More AWS Lambda cons

"The price and versatility of this product need to improve - it is not inexpensive."

"We had some stability issues where we used embedded Zookeeper in production."

"I’d like to see a tool kit specifically targeted at incremental machine learning. It’s already great for scoring previously trained models, but dynamically updating models is currently more of a 'grow your own' kind of thing."

"The development IDE sometimes crashes and freezes."

Pricing and Cost Advice

"Lambda is a good and cheap solution and I would recommend it to those without a huge payload."

"The pricing varies based on the specific solution you're implementing, and in comparison to the value it provides, the overall cost is reasonable."

"The cost is based on runtime."

"I would rate the tool’s pricing a nine out of ten. The solution’s pricing works on a pay-as-you-go basis."

"AWS Lambda is cheap."

"AWS Lambda is a very inexpensive solution. They charge for the number of times we run it. If you run AWS Lambda for one time, they charge around 50 cents or 25 cents for the use. I don't know the exact price, but it's less than a dollar."

"The price of the solution is reasonable."

"I think the price is okay. However, if they add more functionality, they can have better prices. In fact, they should have better and more flexible packages for clients who have greater consumption of Lambda."
