Some of the Redis best practices content has moved

This content from this markdown file has moved a new, happier home where it can serve more people. Please check it out : https://docs.microsoft.com/azure/azure-cache-for-redis/cache-best-practices.

NOTE: Client specific guidance listed below is still valid and should still be considered. I will update this document once all content has been moved.

Create an AMI using Packer

What is Packer?

Packer is a tool from Hashicorp that allows you to create machine images in a variety of formats from a single spec file. This can be a very powerful thing when you want to automate the deployment of applications to a variety (or even just more than one, really) platforms.

In our case, we want to deploy an application to VMware and AWS, and soon to Docker. Doing that with a single spec file gives us

• platforms that are consistent, even if they're different

Fix failing node deployments on AWS Elastic Beanstalk

Elastic beanstalk runs npm install with a system user that has no homedir. During the npm install step, it's expecting a $HOME env variable for the npm cache (which doesn't exist). add this file to your project's .ebextensions directory to have it use root's homedir as a temporary path.

This workaround was provided by AWS support, but it doesn't appear to be documented anywhere. Determining root cause on this was a massive pain in the ass. Sharing this so others don't need to feel the pain.
