We use AWS Lambda and other AWS services for a couple of projects. "Vacation Tracker" project uses the most AWS services. We also use AWS Lambda for Slack Bot, API and notifications. In DynamoDB for DB, we use SNS, SQS, and other AWS services. We saved a lot of time writing the API with AWS Lambda not needing BackEnd programmers. All programmers are Full Stack.
It's an easy way to create API for mockup of the product. It's cheap for a startup product. And, with Claudia JS you can create APIs very fast. With the Claudia Bot Builder, you can create a bot for Slack, Facebook, Viber, and more.
  • No servers to manage.
  • Pay per use.
  • Do not need to be worried about scaling.
  • Faster development cycles.
  • Logs do not load fast.
  • Max 3GB RAM.
It's good for a startup project because you do not need to spend too much money for the server and DevOps teams. With AWS Lambda, you do not need to worry about server managing, scaling, or managed infrastructure. It's free for 1 million requests per month, fewer developers are needed for the backend part, and it has fast deployment.

Don't balk at the cost - start with a serverless solution that scales

AWS Lambdas are the true workhorses powering our ETL (Extract, Transform, and Load), Data Warehouse, and Business Intelligence solution. We integrate with dozens of registration platforms and third-party services, loading fully normalized customer data into RDS and Redshift, enabling machine learning, forecasting, CRM, marketing automation, business intelligence, and performance monitoring.
  • It scales endlessly. We chose AWS's serverless architecture specifically for its ability to start small and scale as needed.
  • Its always available. AWS's geographic redundancy and serverless architecture mean there's no server downtime. Ever.
  • From a PM's perspective, there's a learning curve. We've had to either hire out experience engineers, or absorb the not-insignificant orientation of not-yet-initiated engineers. But I suppose the same is true of anything.
Well suited if:
  • Your organization is fairly well established (see: runway)
  • You're married to AWS Infrastructure
  • You hate servers
Not well suited if:
  • You aren't utilizing AWS's manages services
  • Your organization is still in the boot-strapped stage (trying to run as lean as possible)

At Newstex, we use AWS Lambda for a large portion of our AWS workload. We are slowly transitioning all of our services over to Lambda from our previous EC2 servers. Currently we use Lambda to run feed processing, categorization, and normalization of blog posts. We are also using it to monitor our CloudWatch Logs for anomalies and alert our on-call staff to potential issues. We trigger Lambda from CloudWatch events (scheduled) as well as DynamoDB streams and SQS Queues.
  • Easy to deploy
  • Easy to integrate with DynamoDB
  • SQS Support makes it easier to monitor and integrate
  • Easy to scale
  • Pay for what you use, not idle time
  • Focus on your business logic
  • Some errors are hard to track
  • Hard to plan for costs
  • Maximum of 5 minutes of execution time per invoke
Web requests are perfectly suited for Lambda, as are any events that can happen quickly. As Lambda supports more languages, such as Go and Node.JS, it becomes easy to ignore things like frameworks and just focus on a single function. Keep in mind that Lambda functions do not run constantly in the background, and only run when requested, so they are ideal for spikey workloads on-demand.

AWS Lambda a great way to handle quick process inexpensively.

I am using AWS Lambda to process data for a U.S. Government client's website. There are a number of short term processing items that are required to be performed every day and the cost of running these processes cannot be too high. AWS Lambda fits this bill perfectly. The website delivers the data to the AWS Lambda functions and the data gets processed and then passed back to tthe website via AWS S3.
  • AWS Lambda is great for inexpensive, sometimes free, short term processing.
  • AWS Lambda integrates very well with AWS S3 Storage.
  • Since it is possible to store log files on S3, it is possible to easily process AWS website log information.
  • I think the biggest problem with AWS Lambda are the small number of languages that it currently supports. This number is, however, getting bigger.
  • AWS Lambda would be a bit better if it were possible to have your function run a little longer, however, since it real purpose is to supply fast functions to all who need some short processing, this if too big of a con.
  • It is possible to have the charging kick in on AWS Lambda just because your website or functions get popular or someone is trying to attack you. It would be good if a cap could easily be placed on the chargers so you couldn't go over a set limit.
AWS Lambda is great for fast processing of data that can be placed on Amazon S3 storage. As long as the processing of the function is not longer than what AWS says a Lambda should run for and you do not do much processing, it is great. The cost can also be very good as long as you keep the price in the free area.

Simple server-less services!

Score 9 out of 10
Vetted Review

We've used AWS Lambda to deploy several "serverless services". The ability to quickly deploy functions, with no architecture, across several languages, with interoperability between other AWS components (such as S3), at an extremely low cost is really cool. We use Lambda to automate simple processes as well as to run code in languages that aren't supported by our main stack.
  • Very reasonable prices with billing down to the 100ms
  • Super easy to deploy functions and set up triggers from other AWS services
  • Plenty of examples and code snippets (from Amazon and around the web)
  • Vendor lock-in: While a basic function or microservice might be platform independent, when you start to use AWS APIs and interact with other AWS services, your microservice now relies on the AWS ecosystem
  • A bit intimidating at first, however there are a lot of resources. Amazon could offer more templates and examples though
When to use:
Easily deploys functions/microservices without a server. Deploy code in several different languages (For instance: Your main app is Node.js but you want to launch a Python microservice? Simple!). Automate small tasks between different AWS services.

When not to use:

When you don't really have a microservice and you actually need a server! Or when you're not going to rely on other AWS services to make up for the lack of a server.

An excellent choice for cloud based, serverless functions

AWS Lambda is a great way to perform operations in the cloud without requiring a server. We have used Lambda in our engineering team to help automate AWS related tasks and do so in a way that does not require running an AWS instance. This helped us because sometimes Lambda is one of the most efficient ways to solve a problem that involves the AWS infrastructure.
  • One of the best serverless cloud based functions out there
  • Deep integration with Amazon Web Services
  • Support for a variety of programming languages
  • Deployment of Lambda functions could be a bit more intuitive
  • Amazon could provide more examples of Lambda functions to help get started
  • A Lambda based workflow can be more complex to debug because of all the different functions that may be called as a result of your workflow
Lambda is great when you have specific bite-sized functionality that you can split into multiple discrete functions. It is not well suited for large functions that do quite a bit. Sometimes you are able to split those tasks down into separate Lambda functions that effectively get chained together. For the cases where you can't, it's better to go with a standard backend.

Scalable, low cost computing

Score 10 out of 10
Vetted Review

We currently employ Lambda to do a number of event-driven tasks without our backend infrastructure. This ranges from API services to on-the-fly image manipulation. The reason for utilising Lambda in this fashion comes from a few distinct advantages: ease of integration with other AWS services (i.e. we can trigger it extremely easily), cost and scalability. A number of our services have either very low workloads, and thus it would be wasteful to run services 24/7, or very unpredictable demands - both of which Lambda help us with massively.
  • Pay for only what you use. Because Lambda is billed by the 100ms of execution time, you can run low volume services extremely cheaply.
  • Scalability. Lambda will spin up as many concurrent executions on demand as required to fulfil the triggers (up until a soft limit at least). This means for unpredictable workloads we get reliable execution with minimal costs.
  • Ease of integration with other AWS services - Lambda can be plugged into just about everything and anything within the AWS ecosystem and also can be trigger via APIs from external systems making it very easy to integrate with.
  • Language support is OK, but could be improved. In particular it would be nice to see native support for PHP, given its prevalence, and possibly Ruby.
  • It would be great if there was a way of doing scheduling with a better granularity than 1 minute. For example, if you want to poll something every 15 seconds, it is not straight forward to do this using Lambda and the associated triggers as things stand.
Excellent for pretty much anything which is event driven. If you can consider a way of architecting your system to be micro-service oriented and event-driven then Lambda is a great fit.

On the other hand, if you need something where you are doing polling operations, particularly if its more frequent than once a minute, then there are probably better solutions for you.

AWS Lamda is used for running code, it is used within our team only and not used within whole origination level. Since the organization, does not require to invest money in specialist software like Jenkins. Also, it reduces our team to eliminate a need for Pre-production environment as other environments can be used as Production like env's and code can be tested in other environments. In future, probably, my team may not need specialist Deploy Engineer.
  • No need for specialist deployment engineer
  • It do not require any additional cost for server to debugging a code
  • Time-saving activity
  • We are not fully aware of its use but if it has functionality likewise we have in Unix like operating system where we can schedule deployment then it will be very good.
  • As of now, no one is trained in using any of AWS functionality fully in our team, it requires special skills to use LAMBDA.
  • It also requires setting up of node.js environment, which most of us found difficult.
Its IT future and certainly it will reduce the number of Deployment engineer posts. So, it will be gone cost-saving activity. It will be less appropriate when org system are legacy systems.

AWS Lambda's On-Demand Scripts are Excellent and Easy!

Score 7 out of 10
Vetted Review
Verified User
Review Source
We use AWS Lambda to trigger scripts in response to events in other Amazon Web Services we use. Because AWS Lambda is useful for on-demand processing, we do not have to provision a server to idle in anticipation of the events that trigger its scripts.
  • AWS Lambda is great at responding to triggers from events within the AWS ecosystem. This is important and useful if you use other AWS products.
  • AWS Lambda uses the same policies/permissions system used for users, which makes it easy to limit the scope of the script.
  • AWS Lambda allows you to create scripts in a variety of programming languages, often eliminating the need to learn a new programming language.
  • The version of node.js available on AWS Lambda wasn't up to date, requiring our organization to research older language conventions. It was later updated.
  • There were few official examples of how to interact with S3 from AWS Lambda. We resorted to examples/tutorials found elsewhere online.
The decision to use AWS Lambda is easiest if you've already committed to the AWS ecosystem of products. But AWS Lambda is also useful as a standalone product if you require any on-demand processing that only charges you when it is running. AWS Lambda is less appropriate if you need scripts with a persistent state.

We use Lambda functions as a way to implement serverless code without having to manage an underlying infrastructure. Lambdas are a great way to allow devs to very quickly get things out the door when the main task doesn't rely on any specific hardware or software and just needs to do something to a stream of data. Lambdas and kinesis streams go hand in hand and are very powerful tools when implemented correctly.
  • parsing data
  • log processing and forwarding
  • monitoring the contents of an S3 bucket and performing an action when the contents changes
  • more languages supported
  • cleaner interface
  • better list of example code
Eeveryone should be using Lambda functions for situations where code needs to be executed in response to something happening. Lambdas can be used in situations where you have lots of persistent data but in my opinion, they work better in ephemeral environments. Counting things with Lambdas is hard too, so you should probably avoid that.

Lambdas for the win

Clients transactional system was built using Lambda, consisting of 3 API's and a front facing Node.js application.
High latency transaction speeds were achieved and the autoscaling meant spikey traffic is dealt with.
  • Autoscaling
  • High latency
  • Pay only for execution time
  • Increase the time they 'stay warm' - if they go through periods where the system isn't used, the lambda need a few seconds to start up again
Its good for short bursts of code execution. If I was looking for long code execution times I would consider falling back to EC2. Easy to use and integrate with API Gateway and making RESTful calls becomes a breeze.

I use it for running Alexa skills. These are created using Node.js and I found using AWS Lambda functions to be relatively easy to pick up and use! I’ve utilized a handful of Lambda functions and plan on using more in the future.
  • Documentation is plentiful
  • Setup steps are very helpful
  • Debugging process is great
  • I’d like to see higher versions of Node.js supported natively.
Alexa skills essentially require AWS Lambda and the process is pretty easy to get going.

About AWS Lambda

AWS Lambda is a serverless computing platform that lets developers run code without provisioning or managing servers. With Lambda, users can run code for virtually any type of app or backend service—all with zero administration. It takes care of requirements to run and scale code with high availability. Users pay only for the compute time they consume—there is no charge when their code is not running.

Developers uploading to Lambda don’t have to deal with their code’s environment. It’s a “serverless” service which lets outside code or events invoke functions. Lambda doesn’t store data, but it allows access to other services which do. Users can set up their code to automatically trigger from other AWS services or call it directly from any web or mobile app.
