Overview

We have an autoscaling group of m5.large instances with 250GB EBS root volumes that we use for running our Buildkite test suites. This group scales up from 0 to 40 during the work day and then down again, so each day we see new instances.

We've been seeing every few days that a few of the instances run very, very slowly. Our test suite either takes 100x it's usual time or times out entirely. On the host machine, a basic command like aws s3api head-object --bucket blah --key blah will take 45 seconds.

All instances are m5.large in us-east-1 running the latest Amazon Linux 2 ami-06631de3819cb42f3

** found it ** - I was running an old version of AWS CLI :)

I was able to create a ElasticBeanstalk environment with a EnvironmentName that is longer than what the API's allows...

I can describe the environment, but I can't find the options for it, describe-configuration-options doesn't accept --environment-id... :(

$ env_name=`aws elasticbeanstalk describe-environments --environment-id e-XXXXXXXX | jq .Environments[0].EnvironmentName`
$ echo $env_name
"XXXXXXXX-XXXXXXX-XXX-XXX"

$ aws elasticbeanstalk describe-environments --environment-name $env_name

#SSL Basics

Secure Socket Layer (SSL) is a mechanism to allow information to be securely communicated. Specifically, it is a cryptographic protocol that enables two parties such as a web server and a browser to exchange information securely by encrypting it before sending and decrypting it upon receipt. It is based on the X.509 standards.

##Symmetric and Asymmetric Encryption Encrypting and decrypting requires a secret like a password, which is known as a key. There are two types of key, symmetric and asymmetric. If a symmetric key is used it means that the same key is used to encrypt and decrypt the message. Asymmetric keys consist of a private and public key. The message sender encrypts the message using their private (secret) key and the message receiver can decrypt the message using the senders public key.

Asymmetric keys require more processing resources than symmetric keys. The problem is that to communicate using symmetric keys both parties have to have the symmetric keys first and the question is
