Secure Serverless CI/CD with Codeship, PureSec, and AWS Lambda

When you develop, build, and deploy applications using a serverless architecture, you have no access to the infrastructure on which traditional security controls used to exist. Nonetheless, serverless applications may contain application layer vulnerabilities, which may enable a malicious user to mount application layer attacks.

In this eBook we will talk about Secure Serverless CI/CD with Codeship, PureSec, and AWS Lambda.

An Overview of the Service Mesh and Its Tooling Options

For an app to function at its best, every part of the application stack needs to be optimized and modernized. The way code is deployed is changing as applications are built and deployed in a more distributed manner. The layer that needs to function seamlessly is the networking layer. In modern containerized applications, a lot of focus is on the infrastructure and packaging and deployment of code, not so much on networking. This has been changing recently with the advent of the service mesh.

In this eBook you will learn what a service mesh is and why it is a superior alternative to traditional networking models.

Here is what you will learn in this book:

Using Serverless Functions with AWS Lambda

Serverless functions (Lambdas, in AWS's case) are incredibly useful for configuring the execution of our workload processes. Plus, we only pay for the time and computing power that we use. There’s no need for an ever-running server that’s consuming hosting costs even when it's not in use.

In this eBook you will learn how to execute code on third-party servers – also known as serverless functions – with AWS Lambda.

Here is what you will learn in this book:

How to execute on serverless functions with AWS Lambda
Using AWS Lambda with Ruby and Python

How Docker Streamlines Production Deployments

In this eBook we discuss some core reasons how Docker helps to predictably streamline the deployments of your application across all of your environments, from development through to production. Docker, thus, helps ensure a modern software development workflow that focuses on efficiency, reliability, and repeatability.

Here is what you will learn in this book:

How Docker supports packaged applications (containerization)
How Docker supports “Build Once, Deploy Many Times In Multiple Locations” (repeatability of build environment)
How Docker supports easy rollback to earlier versions should something have gone wrong

If you’ve not considered Docker as a part of your development toolchain yet, we hope that this will motivate you to do so. It’s a tool with a lot of merit, one that’s only getting better.
