Easy to deploy and does not need an initial capital investment on servers
Pros and Cons
  • "AWS Lambda is serverless."
  • "We face some problems with the event-driven execution model."

What is our primary use case?

We have one or two use cases for real-time file processing. We use the event triggers to detect file arrival.

What is most valuable?

AWS Lambda is serverless. It is quick to deploy. The event-driven execution model has improved the project efficiency because it is quick and easy to deploy. However, it also introduced a set of new problems. It is the industry traction ever since the network went fully API.

Since the tool is serverless and it is hosted in the cloud, we do not need an initial capital investment on servers. We can pay as we use. We have integrated the product with other AWS services. We use SNS and SQL. There is an offering from AWS for integrated solutions.

What needs improvement?

We face some problems with the event-driven execution model.

What do I think about the stability of the solution?

The tool is very stable. There are certain things that we have to do to support it, but once we cross the t's and dot the i’s, it works.

How was the initial setup?

The initial setup seems to be very straightforward.

What other advice do I have?

I will recommend the solution to others for serverless computing needs. It’s a quick delivery. We do not have to set up servers before we start deploying. Overall, I rate the product a nine out of ten.

Offers serverless computing with easy integration and good support
Pros and Cons
  • "The initial setup of AWS Lambda is very straightforward and quick."
  • "If you're running a new application with a significant load, you need to be prepared for potential bottlenecks."

What is our primary use case?

Lambda is essentially a serverless computing service offered by AWS. It allows you to run your code or applications without needing to manage servers. You can deploy your IT code or applications, and it seamlessly integrates with other AWS services, like S3 for data storage. You don't need to purchase or manage any servers. So, Lambda offers a way to run applications without the complexity of infrastructure.

What is most valuable?

The best feature of AWS Lambda is its scalability and security. It's a highly scalable service, making it suitable for a range of applications.  

AWS Lambda, like other services offered by AWS, SAP, or Azure, is already quite advanced. However, when considering improvements, it's more about how you write and optimize your applications.

What needs improvement?

There's always room for enhancement in terms of resource allocation and management for high-demand applications.

Performance issues can arise depending on how you allocate resources within Lambda. For example, if you're running a new application with a significant load, you need to be prepared for potential bottlenecks. 

It's essential to control network interactions and optimize for the type of application you're running. Lambda is excellent for small and lightweight applications, but for more resource-intensive tasks, you might need to look at other AWS services or a more distributed storage environment.

AWS Lambda could greatly benefit from enhancements in handling large-scale applications to support heavy workloads. This is actually feasible, but there is a need for further development in this area. 

Additionally, improvements in resource control optimization are crucial. For instance, enabling users to run data-intensive applications using a limited number of resources without compromising performance would be a valuable addition.

For how long have I used the solution?

I have used it for three years.

How are customer service and support?

I have interacted with the AWS support team. They have a large customer base, which sometimes leads to delays, but overall, their support is excellent.

They categorize issues effectively and provide prompt support for critical issues. Even for less critical issues from the customer's perspective, their response is adequate. They are usually quick to respond, especially when the issue is critical, and they provide effective support.

How would you rate customer service and support?

Positive

How was the initial setup?

The initial setup of AWS Lambda is very straightforward and quick.

What other advice do I have?

If you have a data application with a huge number of users that requires frequent user interaction, AWS Lambda may not be the best fit. However, it's suitable for applications with less frequent user interaction, like those accessed periodically, maybe every few minutes or hours.

For lightweight applications, AWS Lambda is a ten out of ten.

Serverless compute platform used to build microservices that can be set up in multiple ways based on experience
Pros and Cons
  • "Lambda is the preferred compute option because of on-demand cost. We don't have to provision any hardware beforehand. We don't have to provision the capacity required for the services because it is serverless."
  • "The first time Lambda is started up, it takes some time to spin up an instance for serving the consumer requests. AWS has been trying to solve this in a variety of ways but have not yet managed to do so."

What is our primary use case?

We are building microservices in Lambda and exposing them via an API Gateway for the end consumer. These microservices talk to DynamoDB, or third-party APIs but can also be event-driven. These microservices carry out specific business functionalities.

We have plans to increase usage in the future. We have been modernizing our usage of SOA technology and rewriting those SOA services on the cloud using AWS Lambda. We are transitioning to a serverless environment using Lambda. 

How has it helped my organization?

Lambda is the preferred compute option because of on-demand cost. We don't have to provision any hardware beforehand. We don't have to provision the capacity required for the services because it is serverless. 

AWS takes care of things behind the scenes and we pay only for usage. We don't have to incur uptime or the upfront cost to procure a EC2 instance or create any ECS service.

What is most valuable?

You can trigger Lambda in various ways including API Gateway events or a S3 object event. You can create a file in SP and it can trigger a Lambda function. You can process the file based on the event and complete asynchronous programming. It supports both synchronous as well as asynchronous programming. It is integrated with variety of AWS services like the S3, SQS or SNS.

You can use Lambda for a variety of use cases. You just have to write a Lambda which can be in various languages including Python, Node.js or Java. There is no limit on what you can do with Lambda because it is integrated with a variety of AWS services. 

What needs improvement?

The first time Lambda is started up, it takes some time to spin up an instance for serving the consumer requests. AWS has been trying to solve this in a variety of ways but have not yet managed to do so. 

Lambda can only run for a maximum for 15 minutes. If you have a job which requires running for more than 15 minutes, you cannot use Lambda for that use case. 

For how long have I used the solution?

I have been using this solution for five years. 

What do I think about the stability of the solution?

I would rate Lambda an eight out of ten for stability. 

What do I think about the scalability of the solution?

This is a scalable solution. I would rate it an eight or nine. You can have 999 Lambda instances running at a particular second at one time. That is the default. It you need to scale above this, you can request for AWS to increase your capacity.

How are customer service and support?

I would rate the technical support an eight out of ten. We do contact the AWS support team if we are stuck or something is not working. They provide their input and we set up a call with them to explain our issues and reach a resolution.

How would you rate customer service and support?

Positive

How was the initial setup?

The initial setup is straightforward. They have variety of ways to set it up via the console, ETK or CFT. You can easily configure Lambda via variety of ways based on your experience. Usually, newcomers will use console which is a UI and makes your task easier. Experienced people will go with CLIs, SDPF or CFTs to create Lambda resources.

We are not just deploying Lambda. We have a variety of AWS services which we combine into one script and we do it via an AWS code pipeline.

I would rate the setup a nine out of ten.

What about the implementation team?

Deployment was done in-house by our own team. The patching of underlying hardware and other maintenance is done by AWS. 

What was our ROI?

We have experienced a ROI using this solution. I would rate it an eight out of ten. 

What's my experience with pricing, setup cost, and licensing?

Lambda is an affordable solution. They offer free requests every month and charge per the compute time. If you are working in a big organization, usually AWS offer a savings plan where you get approximately 70% discount on pricing.

If one is very affordable and ten is expensive, I would rate this solution a two out of ten. Costing is per account. Production will involve a higher cost. 

What other advice do I have?

If you are planning to implement the solution using scripting language like Node.js or Python, it's better to rather use traditional programming language like Java, or .NET, because Lambda runs faster and more efficiently. We implement it using these scripting languages as the first choice.  

It is important to understand your use case properly and if Lambda is a good fit. Solutions such as Docker, Kubernetes, OpenShift or normal EC2 instances may be a better fit for your business.

I would rate this solution a nine out of ten. It integrates well with variety of AWS services which makes the event-based programming easy. Lambda is well suited to a variety of use cases or applications.

Saves setup time; stable and scalable
Pros and Cons
  • "Thanks to this solution, we do not need to worry about hardware or resource utilization. It saves us time."
  • "My opinion is that the integration could be improved in this solution. We have had some difficulties integrating the EC2 module, but we found a solution for that by ourselves."

What is our primary use case?

Our primary use case for AWS Lambda is a backend service module. Thanks to this solution, we do not need to worry about hardware or resource utilization. It saves us time. 

It saves us a lot of setup time. And, because it's our code, we will use Lambda. Lambda is the best AWS product we can use for running our code and it is very quick for the developers. All they have to do is commit their codes and, once we set up our code pipeline once after committing the code and building and deploying to our Lambda, the project will be up and running in the market. This setup is better than managing on EC2. We don't need to use EC2 in this case. 

What needs improvement?

My opinion is that the integration could be improved in this solution. We have had some difficulties integrating the EC2 module, but we found a solution for that by ourselves. I would say the integration needs to be improved.

For how long have I used the solution?

I have been using AWS Lambda for about three years.

What do I think about the stability of the solution?

This solution is very stable.

What do I think about the scalability of the solution?

My impression is that this solution is 100% scalable. The Lambda function is the most powerful product that the developer needs. 

We have one Lambda used by 50 to 100 people, and then we have another Lambda method that could be used by thousands.

How was the initial setup?

My impression is that the setup was quite straightforward.

What other advice do I have?

Overall, I would rate this solution a 10, on a scale from one to 10, with one being the worst and 10 being the best. I would definitely recommend this solution to other people.

Being serverless, it optimises resources and also provides the parallelism of computation
Pros and Cons
  • "It enables the launch of thousands of instances simultaneously,"
  • "Lambda can only be used in one account; there's no possibility to utilize it in another account."

What is our primary use case?

Lambda is basically a serverless computation service. We are partners with AWS and I'm a consultant. 

How has it helped my organization?

Because Lambda is serverless, it has optimized our resources. There's no need to worry about capacity. 

What is most valuable?

Lambda is very handy because it gives us the parallelism of computation. If you want to launch thousands of instances simultaneously, it can be done on one site. The solution has a 15-minute computation limit but you can create a chain with the same code so that the output automatically switches to another functionality after 15 minutes. 

What needs improvement?

The only issue is that if you have Lambda in one AWS account and want to utilize it in another account, it can't be done. It's a limitation of the solution. S3 bucket provides that option with its resource access management. If you have a Python library and want to package it, you have to create the package of those libraries. It requires changing the conflict file and the patent library to create the package because the configuration is a little difficult for beginners. They should simplify package creation and configuration. Writing test cases is a little difficult because of the memory and short duration. Your computation has to be finished within that time limit. 

For how long have I used the solution?

I've been using this solution for five years. 

What do I think about the stability of the solution?

We haven't had any performance issues because Lambda automatically gauges the kind of computation required.

What do I think about the scalability of the solution?

The scalability is excellent and there is no capacity limit. 

How was the initial setup?

Provided the person deploying the solution knows the format of the input, the setup is relatively simple for experienced users. Deployment doesn't take long because of the integrated machine services. Our implementation was carried out in-house. It doesn't require any maintenance once it has run for a month.

What's my experience with pricing, setup cost, and licensing?

Licensing costs are reasonable even though you have to pay for the computation and for the volume of data. Once the work is done, the storage is freed up so you only get charged for the instance. 

What other advice do I have?

If an organization wants to go serverless, Lambda offers a truly serverless service. Even though there are some areas that could be improved, I rate this solution 10 out of 10. 

Which deployment model are you using for this solution?

Hybrid Cloud
