Serverless, infinitely scalable, and works very well for atomic and fairly non-persistent transactions
Pros and Cons
  • "It is serverless and scalable. It can scale infinitely. You don't have to worry about the size of the servers that you're pre-allocating. You don't have to build server scale-out models. Auto scale and other similar features are just inherent in Lambda. So, for atomic and fairly non-persistent transactional units of work, Lambda works very well."
  • "My engineers work with it on a daily basis. I just don't have enough depth of knowledge about what kinds of edge cases they may have tried and found lacking. There may be some issues with some language support at one point or another because we couldn't get the underlying libraries in there. A lot of what we do is either in JavaScript, Python, or some of the non-compiled languages. I'm not sure if we've ever tried building a C# solution, for instance, in Lambda or a Java solution in Lambda. It doesn't mean those aren't its capabilities. I would rather refer to my engineers for where the boundaries are."

What is our primary use case?

Usually, it is for small transactions. They're very atomic transactions. For example, we built a solution for an ad platform where an electronic ad runs for about 15 seconds a piece. Every time one of the ads runs, we have to record where did it run, how long did it run for, who was in the room, and how many people. There is a bunch of data around that. We typically send that transaction through an Amazon Kinesis pipe into a Lambda function, and then Lambda will take it and store it in S3 or target it to Redshift or put it in some kind of data store. That's one example of what we would use it for. That's a typical model for Lambda. 

What is most valuable?

It is serverless and scalable. It can scale infinitely. You don't have to worry about the size of the servers that you're pre-allocating. You don't have to build server scale-out models. Auto scale and other similar features are just inherent in Lambda. So, for atomic and fairly non-persistent transactional units of work, Lambda works very well.

What needs improvement?

My engineers work with it on a daily basis. I just don't have enough depth of knowledge about what kinds of edge cases they may have tried and found lacking. There may be some issues with some language support at one point or another because we couldn't get the underlying libraries in there. A lot of what we do is either in JavaScript, Python, or some of the non-compiled languages. I'm not sure if we've ever tried building a C# solution, for instance, in Lambda or a Java solution in Lambda. It doesn't mean those aren't its capabilities. I would rather refer to my engineers for where the boundaries are.

For how long have I used the solution?

It has probably been five or six years since we've been migrating functionality from EC2 instances to Lambda.

What do I think about the stability of the solution?

Its stability is really good, and it is also highly available. The stability is inherent, but it also naturally gives you a high availability model because you don't have to have multiple EC2 instances running in, for instance, different regions. It is baked into the model. So, you can allow for inter-region Lambda functionality. It all becomes very highly available across Amazon's footprint.

What do I think about the scalability of the solution?

It is endlessly scalable. In terms of its users, Lambda is typically baked into the middle of an application somewhere. Our ad platform solution is a fully-automated IoT solution. So, there are no people involved. The whole thing is automated from end to end. So, sometimes people don't even come into the equation.

How are customer service and support?

We probably do or have dealt with their support, but that would be at the end engineer level. It is not something to which I would have much visibility. 

How was the initial setup?

It is straightforward in my understanding. From the engineering perspective, I haven't gotten feedback that it is at all burdensome.

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

You're not paying for a server if you're not using it, which is another reason I like it. So, you're not paying if you're not using it. It scales, and you're charged based on usage. It all depends on the use case. Some can be extremely inexpensive if you have very low volume transaction rates. That way, you don't have to fire up and absorb the cost of the servers just sitting there waiting for a transaction to come through. You're only paying when you use it. So, depending upon the use model, Lambda could be highly efficient relative to an EC2 solution. You don't have to have things reallocated.

What other advice do I have?

Understanding what your use model looks like is the key. All these cloud providers have so many different ways of implementing a solution that you really have to understand the near-term and long-term picture for that solution. What does it look like? When you're first building it, there might be a more expedited way to get it off the ground, but that may not scale properly, or your cost can get out of control. So, it is very important to align the right set of features within an AWS or Azure environment for not just getting the initial MVP built but also making sure that you're building it in a way that allows scaling and optimization of the cost model over time as the application scales. There's no one answer. The way you build the solution in the cloud is very dependent upon what the use case is.

From my perspective, not being at the engineering level, I would give it a nine out of ten. There is always room for improvement, but it has been a terrific advance over what was previously available just having to build everything in EC2.

Advantageous triggering feature but would benefit from enhanced editing functions
Pros and Cons
  • "By using Lambda, we can use Python code and the Boto3 solution."
  • "Lambda would benefit from a debugging feature as well."

What is most valuable?

I have found this solution very useful. By using Lambda, we can use Python code and the Boto3 solution. 

The triggering feature is also valuable. For example, if we are using Kafka, we need to be aware that the language comes in Kafka when we write in Python, and that we are transforming our data into the meaningful server and dumping that into the S3 bucket.

What needs improvement?

I would like to see a find and replace function as part of Lambda's future releases. Currently, if we want to replace a code, we copy the code into Notepad, then find and replace it, and then copy that to Lambda. This would improve the editing function of the product.

Lambda would benefit from a debugging feature as well. For example, if you want to debug code running in Python and deployed in Lambda, it would be beneficial to have a debugging feature.

For how long have I used the solution?

I have been working with AWS Lambda for one year.

What do I think about the stability of the solution?

The solution is stable. There are times when we do need to refresh when we make changes and deploy them. This seldom occurs.

What do I think about the scalability of the solution?

We have five developers using Lambda. 

How are customer service and support?

Technical support can take a long time to respond. I would rate their service a seven out of 10.

How would you rate customer service and support?

Neutral

How was the initial setup?

The initial setup of AWS Lambda is simple.

What other advice do I have?

I would rate this solution a seven out of ten overall. 

Which deployment model are you using for this solution?

Good performance and easy to use and install
Pros and Cons
  • "Some of the most valuable features are that it's easy to install and use. The performance is also good."
  • "Lambda could be improved in the sense that some of the things done with Lambda function take some time. So the performance could be better and faster."

What is our primary use case?

We have a DNS as a service and NAS as a service, which integrates, and we use Lambda functions there. We have a lot of applications that we use Lambda for. 

This solution is cloud-based. 

What is most valuable?

Some of the most valuable features are that it's easy to install and use. The performance is also good. 

What needs improvement?

Lambda could be improved in the sense that some of the things done with Lambda function take some time. So the performance could be better and faster. 

For how long have I used the solution?

I have been using Lambda for many years. 

What do I think about the stability of the solution?

This solution is stable. 

What do I think about the scalability of the solution?

This solution is scalable. 

I think, eventually, we will increase our usage. We need to move some of our services to Lambda. 

How are customer service and support?

Amazon's technical support is good. 

Which solution did I use previously and why did I switch?

Before implementing Lambda, we had legacy types of solutions. 

How was the initial setup?

The installation could be faster, but I believe it's a straightforward process. I manage a team that handles the installation, so I can't comment on the specifics of the installation process. Within the team that handles maintenance and deployment, we have two engineers. 

What about the implementation team?

We implemented this solution through an in-house team. 

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

We don't need to pay for licensing to use Lambda. 

What other advice do I have?

I rate AWS Lambda an eight out of ten. I would recommend AWS Lambda to others. We provide a lot of services, part of which is that we write Lambda functions.

How was the initial setup?

The installation is straightforward. The process took us under three hours, and we did it ourselves. For deployment and maintenance, we have a team of 10 engineers and developers. 

What about the implementation team?

We implemented this solution through an in-house team. 

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

For licensing, we pay a yearly subscription. 

What other advice do I have?

I rate AWS Lambda a nine out of ten. To those looking to implement AWS Lambda, I would recommend this solution, and say that Lambda has a learning curve in order to enhance the service when using it for the first time. I would advise the user to study hard to use Lambda as a tool.

Programming is getting much easier and does not need a lot of configuration
Pros and Cons
  • "Amazon takes care of the scalability. That's the right way. It's automatic and it's fully managed. That's one benefit of Lambda."
  • "I think that perhaps Lambda could explore its functionality more."

What is our primary use case?

AWS Lambda has serverless programming, like Logic Apps from Azure. You just configure the run-time and then they start coding. It is event-driven. It started with my obtaining Salesforce. Salesforce is a low-code and non-code program and totally SAS. Everything starts from the event, from the trigger. You get the trigger and you work at the program. You have some other models, maybe faster or fancier models. But in my opinion, this kind of program is started by locating the system and identifying where the trigger and entry point of the program are. Then you get the full advantage of the program. You don't need to worry about any infrastructure.

I think this is the future. Compared with the EC2, you don't have to pay anything if you don't run it. Otherwise, with EC2 when our client provisions the system and the instances, you always have to pay. There are other tremendous advantages, like flexibility. After you provision EC2 you can write something that does not totally follow the cloud convention. You use it to provision the container. With the program you need to have those 10 principles of cloud computing. Especially recently, within the past four or five years, I have gotten away from DevOps, or the software development life cycle. Even though I researched the product portfolio from DevOps and then the life cycle for DevOps, I try to position myself as an architect with hands-on experience.

In my opinion, Lambda is very similar to Salesforce, which is the original for the SaaS platform and is an extremely low-code environment. With Microsoft and AWS you can say, "Okay. You can choose whatever language you need to make it even more flexible." 

Everything is the cloud. Lambda is a fully managed service. If you want to do it either as a private cloud or on-premise, I'm sure you can do that, too. But I don't know how to manage the pricing structure. But then you've lost the point of Lambda because if you do not use it, you do not pay. Again, I just want to emphasize, I'm not a Lambda expert. But, logically thinking, the big advantage of serverless programming for the customer is that you just use it and pay. Pay and go. You don't need to provision anything.

All my experience with AWS Azure is on the public cloud. We do not get too deep. In IBM we do. When we do sales training we always get the private cloud on-premise. There are many reasons for this. One reason is that IBM lost the battle for the public cloud so we get into it much deeper. We go to the enterprise and we can deploy programs to your data center and offices. But for the tech data for AWS and Azure, we are all using the public cloud as a showcase when we talk to the customer and to the retailer.

What is most valuable?

The number one feature with AWS Lambda is that it is fully managed. From the developer's perspective, you get the coding much more easily. Now many situations are not using code. You plug in, assemble it, and configure it. Lambda makes it low-code. I come from being a Java certified developer for 15 years. You configure the environment for deployment just like in DevOps. That was always the most challenging part as a developer. You identified when to trigger it. If the program can't facilitate it, then 80% is gone. With 20% you just Lose Syntax. You can use Lose Syntax with any programming language as a reference finding out the variables, the statements, the loop, and what other kinds of things you can do. Just follow that to where you can plot it into your business system. 

They might think to have the business benefits say, "Hey, if you don't like it, no need to pay." So, potentially, you can save. If the future is going to be serverless, that's what I think the future of something like Salesforce will be. Programming is getting much easier and does not need a lot of configuration because step-by-step abstraction starts from the infrastructure service. You can replace your hardware, but you still need to do a lot of things in the abstract. The environment now is totally fully managed. I'm not sure if we're totally aligned there. I always talk against those aspects in the Salesforce situation. But I believe Lambda is a comparable peer, apples to apples.

What needs improvement?

I can only speak from the user experience. Salesforce integrates SharesPost efficiently. How? They say, "Okay, I invented another language called Apex. Forget about anything else. This is my language." The benefit of this language is that everything is simplified. Your system is super easy to maintain. But AWS then assures you that they are flexible, that they have a collection of 10 or 20 languages, and you just choose your environment and range. That's the reason I appreciate Salesforce. They always make things easier. They have their loop reasoning because they are a different kind of company. Microsoft and AWS really get the full spec. They want to own the business. But Salesforce data wants the simplest way.

So, this is my understanding and unique experience.

I think that perhaps Lambda could explore its functionality more.

For how long have I used the solution?

I have been using AWS Lambda for a few months.

What do I think about the stability of the solution?

I didn't explore enough information to evaluate that.

What do I think about the scalability of the solution?

I didn't experience the scalability personally, only from my reading. Amazon takes care of the scalability. That's the right way. It's automatic and it's fully managed. That's one benefit of Lambda.

We have all kinds and sizes of resellers. There are large enterprises and small businesses. It's different. And some of them are product based, they are creating their own products. Some of them are consultant based. It's really different. Tech data is different vs. a business model.

How are customer service and technical support?

I contacted support many times. My experience was very little and I just saw how Lambda was working, to try to understand if it is okay.

Which solution did I use previously and why did I switch?

I don't actually use AWS Lambda. I'm a distributor. I try to explain solutions to the vendor. I previously used Salesforce Apex. I use the Azure Logic App service.

Salesforce does not have so many options to choose from, such as Java or C++. Salesforce said, lets invent a language. They call it "invent" but actually they just made a simplified edition of Java and eliminated a lot of complex features. Now all the syntax is the same. Salesforce is a business company. They focus on business solutions development and they make the customer's lifecycle development simple. AWS really does not stick to any business because they are a technology company.

Let me explain the similar things that Lambda has to Salesforce. When you get the event you have to see our form. With the sales approval process, if you have the 50% to get to the half million and above, you need the vice president to get the approval. You can use this trigger based serverless program. All you want to do is to write down the logic and then put it under the trigger of whenever a certain number changes in the half billion, and then you need to do the multiple steps.

This kind of programming is easily defined in the business. All you need to do is get the logic done, get it tested, see the steps you are doing, and then fix up the errors. As for Lambda, as I said, I've just experienced two very simple examples in the AWS, but they were the same thing.

Logic App and Lambda should be doing the same thing - fully managed coding. You focus on the logic triggered by the certain events. And there are other additions within the Lambda family. It can be scheduled as a batch job. I don't think it's originally lack of motivation from the serverless. The serverless is from the trigger.

How was the initial setup?

The initial setup is straightforward. If you follow a 30 or 45 minute lab, it seems pretty clear.

What other advice do I have?

Everybody should check out AWS Lambda. That's why I didn't explore much and it was at the top of my list. This is a fully managed model. The number one. This is for the future. In the future, many of the EC2 applications may be replaced by Lambda. If I started something from scratch, I would try to use Lambda. It's much simpler. It can simplify a lot. If you add the scalability into the picture, it could have 80% or 90% of the complexity. They are very important. All the servlets are very important from a cloud computing perspective.

On a scale of one to ten, I would rate AWS Lambda an eight.

I am a fan of the no-code, low-code if you consistently improve to make it even simpler. Maybe they could do something to simplify the language. I'm not sure if Lambda has the code for the Microsoft Logic App, which means they can eliminate most of the code and everything becomes drag and a drop. Because they eliminated those "if errors." They have those kinds of functions. I think mostly because I have not explored the whole portfolio of AWS. I believe there is a full suite of them.

I believe their full suite of the service is complemented with Lambda. But I do believe the competition is going to make it simple with low-code, no-code. There is no-code, low-code and also no infrastructure. That is going to be the key. Also, maybe you can have the Lambda ecosystem and have some component of the module built above the Lambda so that people can make graphing and plotting even easier. This is not just any software, you get the module there which is much better. But AWS is big enough to neutralize the ecosystem. I believe it will come but the people don't have the patience to start from scratch these days.

Seamless integration with cloud for smooth code execution
Pros and Cons
  • "AWS Lambda is entirely stable."
  • "A very minor improvement would be to simplify the instructions on setting a trigger, as I had to read through them multiple times at the start."

What is our primary use case?

Essentially, I use AWS Lambda to run Python code. Usually, I set up triggers for other parts of AWS. It's really basic programming tasks.

What is most valuable?

AWS Lambda is more integrable than other code software, which is a significant advantage. Given my software development experience, I find its integration with the cloud easier than with other platforms. There haven't been any problems while using it during my three-month internship.

What needs improvement?

A very minor improvement would be to simplify the instructions on setting a trigger, as I had to read through them multiple times at the start.

For how long have I used the solution?

I have used AWS Lambda for three months.

What do I think about the stability of the solution?

AWS Lambda is entirely stable. I never encountered any issues while using it.

What do I think about the scalability of the solution?

I haven't used it extensively, however, it seems scalable. During my internship, scalability hasn't been critical to what I've used it for.

How are customer service and support?

I have never needed to communicate with technical support for AWS Lambda.

How would you rate customer service and support?

Positive

How was the initial setup?

The initial setup was extremely easy. AWS Lambda is significantly easier compared to other IDEs or Visual Studio Code.

What other advice do I have?

There is no specific advice I can provide at the moment because I've only done a short internship. Overall, I would rate AWS Lambda a ten out of ten.

Good monitoring and visibility but it's good if the timeout can be increased
Pros and Cons
  • "The stability is good."
  • "We've had to revamp the way that it works due to that 15-minute timeout limitation."

What is our primary use case?

We have used Lambda for

batch processing for specific schedules.

different bot functions that run regularly,

Application business logic

How has it helped my organization?

Easy to impliment without any environment provisioning

What is most valuable?

 The initial setup is straightforward. 

The stability is good.

It has good monitoring. the visibility is great.

What needs improvement?

From a very high-level perspective, it is a good solution, however, there are certain limitations. This becomes challenging for us. Specifically, a limitation is Lambda cannot continuously execute for more than 15 minutes. That could be one limitation. On an implementation level, there are certain limitations that I know about yet would not be the best person to explain as I am not technical.

The execution timeout can be increased so that if we have a lengthy process, it will not fail before their timeouts. We've had to revamp the way that it works due to that 15-minute timeout limitation.

For how long have I used the solution?

We've been using over 2 years

What do I think about the stability of the solution?

It's very stable, and it's easy to monitor. They have all the required logs and dashboards available on AWS to see the progress. The visibility of it also is good when a Lambda runs and completes.

What do I think about the scalability of the solution?

I would not say it's scalable in terms of usage. As the demands increase it is scalable. But if the lambda need more time to process it's not scalable beyond 15 mts.

How are customer service and support?

I've never dealt with technical support. I can't comment on their services. 

How would you rate customer service and support?

Positive

How was the initial setup?

It seems to be a straightforward process. However, I'm not directly totally involved with the Lambda implementation.

What about the implementation team?

We are implementors and can set up the solution for clients. 

What was our ROI?

The ROI is very good. It's a positive thing as there's no investment at all. It's purely on usage you have to pay. There's no upfront investment required, and it's only on the requirement that you have to choose Lambda. With the cost not being very big, the ROI is very good.

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

The cost is based on the number of Lambdas used if I'm not mistaken. It's only a usage charge, not a license charge.

What other advice do I have?

We are an extensively using

I'd recommend the solution to other users and organizations. 

With time-out limitation, it's not a perfect fit for the batch process which takes more than 10 min.

A Stable Serverless Event-Driven Compute Service that requires some Improvement with Memory
Pros and Cons
  • "Lambda being serverless is a great feature that is appropriate for our use cases."
  • "Memory limitation is one of the weaknesses of AWS Lambda and as a result, we have to use several Lambda, instead of just one. Recently, I met with an Amazon employee, who is responsible for Lambda as a product. It appears Amazon has some plans with Lambda, so I don’t have to add something to the additional features."

What is our primary use case?

In our organization, we have a huge number of users using Lambda, approximately around 100. We are using Lambda based on several considerations like costs, and scalability and it provides us with high availability and scalability in our processes.

What is most valuable?

Lambda being serverless is a great feature that is appropriate for our use cases.

What needs improvement?

Memory limitation is one of the weaknesses of AWS Lambda and as a result, we have to use several Lambda, instead of just one.

Recently, I met with an Amazon employee, who is responsible for Lambda as a product. It appears Amazon has some plans with Lambda, so I don’t have to add something to the additional features.

For how long have I used the solution?

I have been using AWS Lambda for a couple of years.

What do I think about the stability of the solution?

I would rate the stability eight out of ten because of certain bugs in the solution.

What do I think about the scalability of the solution?

 I would rate the scalability eight out of ten because we have certain limitations in terms of memory and size. I see it as a gradual shift of mindset rather than limitation, where AWS Lambda is trying to incorporate everything according to the industry standards, which is everything is domain-driven design and suppression of microservices. Some people even have issues with the User Interface (UI).

How are customer service and support?

We have a special collaboration with AWS, so we have regular meetings with AWS and Amazon, to report issues and they further report it to the concerned team. We have meetings, face-to-face and evaluation meetings with them and their solution engineers.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

We previously used Azure and Volvo

How was the initial setup?

The initial setup is straightforward. 

What about the implementation team?

I implemented the solution  by myself because I was once a tech lead. 

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

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.    

What other advice do I have?

I would rate six out of ten overall for AWS Lambda and all the Lambda solutions,. Because we don’t have the solution for each of our use cases. It is not available in various aspects and sometimes, it is not suitable.

Which deployment model are you using for this solution?
