I was a little restricted in my thinking the first time around and I’ve come to see FaaS as something not quite stateless, since caching state in a Lambda instance that might stick around for 5 hours is a perfectly reasonable idea. I also rewrote the section on Startup Latency since Cold Starts are one of the big “FUD” areas of Serverless.

Then they tried to scale it to cope with high traffic and discovered that some of the state transitions in their step functions were too frequent, and they had some overly chatty calls between AWS lambda functions and S3. They state in the blog that this was quick to build, which is the point.

DynamoDB Streams is the enabling technology behind two other features announced today: cross-region replication maintains identical copies of DynamoDB tables across AWS regions with push-button ease, and triggers execute AWS Lambda functions on streams, allowing you to respond to changing data conditions. Let me expand on each one of them.

Unlike a traditional virtual machine-model where customers must build and manage an entire VM, serverless computing provides the ability to purchase only the CPU cycles and memory needed to support an application using an event-based pay-per-use model. When an application is triggered, it can cause latency as the application starts.

Amazon Lambda. One of the most exciting technologies we have built lately at AWS is Amazon Lambda. Developers really have flocked to using this serverless programming technology to build event driven services. Today Amazon Lambda is entering General Availability.

The paper examines the implications of microservices at the hardware, OS and networking stack, cluster management, and application framework levels, as well as the impact of tail latency. The top line shows the change in tail latency across a set of monolithic applications as operating frequency decreases. Hardware implications.

After all, we’ve been doing that forever with the 2nd-level cache of ORMs , and it is highly encouraged in e.g. the AWS Lambda programming model — which was born on the cloud— to help mitigate function start-up times. The network latency of fetching data over the network, even considering fast data center networks. Who knew! ;).

Three years ago, as part of our AWS Fast Data journey we introduced Amazon ElastiCache for Redis , a fully managed in-memory data store that operates at sub-millisecond latency. It enables customers to run their Redis nodes at higher memory utilization without risking swap usage during events such as snapshotting and replica synchronization.

For example, to reduce latency, serverless platforms try to reuse the same function instance to process multiple requests. events may be retried, depending on how you have configured your retry policy). Most platforms run functions at least once in response to a single event, which can cause problems when functions have side-effects.
