Implementing Cloud Design Patterns for AWS - Second Edition

Overview of this book

Whether you're just getting your feet wet in cloud infrastructure or already creating complex systems, this book will guide you through using the patterns to fit your system needs. Starting with patterns that cover basic processes such as source control and infrastructure-as-code, the book goes on to introduce cloud security practices. You'll then cover patterns of availability and scalability and get acquainted with the ephemeral nature of cloud environments. You'll also explore advanced DevOps patterns in operations and maintenance, before focusing on virtualization patterns such as containerization and serverless computing. In the final leg of your journey, this book will delve into data persistence and visualization patterns. You'll get to grips with architectures for processing static and dynamic data, as well as practices for managing streaming data. By the end of this book, you will be able to design applications that are tolerant of underlying hardware failures, resilient against an unexpected influx of data, and easy to manage and replicate.

Containers


Containerization is the method of packaging your applications for virtualization. The images created allow you to easily execute your containers in a variety of manners. We can install Docker on our Cloud9 instance:

sudo yum install -y docker
sudo service docker start
# The below command will tell us if the docker daemon is running
docker info

Let's look at a sample Dockerfile at https://raw.githubusercontent.com/Docker-example/alpine-wordpress/master/Dockerfile:

# Installing dependencies
RUN apk add --no-cache --virtual .build-deps unzip
RUN apk add --no-cache apache2 php7 php7-apache2 php7-openssl php7-xml php7-pdo php7-mcrypt php7-session php7-mysqli php7-zlib su-exec
RUN mkdir -p /run/apache2 /run/httpd
# Work path

# Download & install wordpress
ADD https://wordpress.org/wordpress-${VERSION_WORDPRESS}.zip ./
RUN unzip -q wordpress-${VERSION_WORDPRESS}.zip -d ./ && \
