Amazon AWS introduced almost eighty new services or service enhancements this year at re:Invent. Let’s go over a few of the more important ones.

Serverless

Serverless was one of the main focuses of re:Invent 2019. The big announcement was the launch of ‘provisioned concurrency’ for Lambda. Currently, there is some latency the first time Lambda is invoked because of ‘cold starts’, when containers need to initialize in the background to do processing for your functions. Provisioned concurrency mitigates this by allocating a pool of pre-initialized Lambda containers in the background. This should allow for better latency when a Lambda function is initialized for the first time.

A few other major announcements in the serverless compute space:

Security

IAM Access Analyzer was the biggest security announcement from re:Invent. This new feature continuously monitors your IAM policies for changes and alerts if anything has changed. When an IAM policy violates your security and access standards, it can be remediated faster.

Other major releases and announcements in the security space:

Compute

ARM based compute is the coolest thing that came out of the major compute announcements. Graviton processors, custom ARM based CPUs designed by Amazon, can perform almost as well as x86 CPUs at a fraction of the cost.

Other major releases and announcements in the AWS compute space:

Networking

The big announcement here seems to be AWS Wavelength, AWS services embedded into the datacenters of telecommunications providers. This will provide very low latency for sensitive applications.

Other major networking releases and announcements:

Database

Enterprise

AWS Outpost was announced in 2018, but is now generally available. This allows for true hybrid functionality for the cloud with AWS services on-prem and in the public cloud. VMware also offers VMware Cloud on AWS Outpost for customers that want to bring the strengths of AWS and VMware together in their datacenters.

That’s about everything we’re going to cover. There was so much more announced this year, but these are what I think they key highlights are for. Thanks for reading!
