Lambda Layers and Runtime API are two new features which enable developers to publish and share libraries and runtimes that are compatible with AWS Lambda. Use of Layers allows separation of concerns. Publishers can build reliable and hardened software, and share it as Lambda Layers with other AWS developers to consume. Application developers can consume one or more layers in their functions which lets them focus on writing business logic. The Lambda Runtime API codifies the runtime calling conventions and integration points of a Lambda compatible runtime. By leveraging the API, developers can implement fully featured Lambda runtimes that support the Lambda programming model. In combination, these two features allow developers to share their runtimes with others as Layers, and allow function developers to seamlessly use them with their functions. In this session, Marco will deep dive into how to use the Layers and Runtime API capabilities to bring your own runtimes and libraries to Lambda.

A way to centrally manage code and data that is
shared across multiple functions

Lambda LayersUseCases
• Custom code, that is used by more than one function
• Libraries, modules, frameworks to simplify the implementation of your
business logic

7. © 2018, Amazon Web Services, Inc. or its affiliates. All rights reserved.
Lambda LayersBenefits
• Enforce separation of concerns, between dependencies and your custom
business logic
• Make your function code smaller and more focused on what you want to
build
• Speed up deployments, because less code must be packaged and
uploaded, and dependencies can be reused

8. © 2018, Amazon Web Services, Inc. or its affiliates. All rights reserved.
Using Lambda Layers
• Put common components in a ZIP file and upload it as a Lambda Layer
• Layers can be versioned to manage updates
• Each version is immutable
• When a version is deleted or permissions to use it are revoked, functions
that used it previously will continue to work, but you won’t be able to
create new ones

9. © 2018, Amazon Web Services, Inc. or its affiliates. All rights reserved.
Using Lambda Layers
• In the configuration of a function, you can reference up to five layers
• One of which can optionally be a custom runtime
• When the function is invoked, layers are installed in the execution
environment in the order you provided
• The overall, uncompressed size of function and layers is subject to the usual unzipped
deployment package size limit (256MB)

10. © 2018, Amazon Web Services, Inc. or its affiliates. All rights reserved.
HowLambda LayersWork
• Order is important because each layer is a ZIP file, and they are all
extracted in the same path
• /opt
• Each layer can potentially overwrite the previous one
• This approach can be used to customize the environment
• For example, the first layer can be a custom runtime and the second layer adds specific
versions of the libraries you need
• The storage of your Lambda Layers takes part in the AWS
Lambda Function storage per region limit (75GB)

Lambda LayersPermissions
• Layers can be used within
• An AWS account
• Shared between accounts
• Shared publicly with the broad developer community
• AWS is publishing a public layer which includes NumPy and SciPy, two
popular scientific libraries for Python
• This prebuilt and optimized layer can help you start very quickly with data processing and
machine learning applications

Lambda RuntimeAPI
• You can now select a custom runtime in the console (provided in the
API/SDKs/CLI) as the runtime of a Lambda function
• With this selection, the function must include (in its code or in a layer) an
executable file called bootstrap
• The runtime bootstrap is responsible for the communication between your code and the
Lambda environment
• Your code can use any programming language

19. © 2018, Amazon Web Services, Inc. or its affiliates. All rights reserved.
Runtime Boostrap
• The runtime bootstrap uses a simple HTTP based interface to
• get the event payload for a new invocation and
• return back the response from the function
• Information on the interface endpoint and the function handler are shared
as environment variables

20. © 2018, Amazon Web Services, Inc. or its affiliates. All rights reserved.
UsingCustomRuntimes
• For the execution of your code, you can use anything that can run in
the Lambda execution environment.
• For example, you can bring an interpreter for the programming language of your choice.
• You only need to know how the Runtime API works if you want to
manage or publish your own runtimes
• As a developer, you can quickly use runtimes that are shared with you as
layers
• Custom runtimes can be shared as layers so that developers can pick them up and use their
favorite programming language when authoring Lambda functions

QuickAccessToolbar
PowerPoint has a toolbar populated with icons that
perform common tasks. This can be a great way to save
time, removing the need to repeatedly navigate through
menus.
You can customize your Quick Access Toolbar to add
buttons for alignment, formatting, and other adjustments
you’ll be making frequently. To do this, on the far right of
the Quick Access Toolbar, select the down arrow, and
select More Commands.
Here, you can browse dozens of different commands, add
and remove commands, and even export a Quick Access
Toolbar to open it on another machine.

Animation options
The four options of animation are:
Entrance animations (green) which
describe the animations that bring
an object onto the slide.
Exit animations (red) which describe
the animations that take an object
off the slide.
Emphasis animations (yellow) which
affect objects but don’t bring them in
or move them off the slide.
Motion paths (line) move the object
around the slide. In addition to speed,
motion paths also have “easing,” which defines
how quickly the object begins or ends moving.
The following animations are acceptable to use:
Fade in/Fade out
Grow/shrink
Lines

The Animation Pane
provides a detailed view
of all the animations
happening within your
slide.
This includes the slide element's
name, the duration of its
animation, and when the
animation will start.
To access the Animation Pane,
select the Animations tab, and
click Animation Pane.

Photography
1. The point of view should be top down, ground up,
or human sight line.
2. Color aligns with the overall AWS palette. Black and white
is not approved.
3. Don’t add gradients over photography.
4. Conceptual/abstract/pattern photos can be used but need to
reference characteristics of a product or service that doesn’t have a
specific physical metaphor (i.e., speed, security, AR/VR).
5. We do not show servers, databases, racks, or
infrastructure hardware.
6. Licensing images is often not as expensive as you may think for a
single use in a PowerPoint presentation. If you are looking for
unique images or photographs for your slides, try some of these
options to legally license use of the image:
