- I think I have to get better at testing like the implementation details of.
- When I’m sort of not motivated yet, I can do simple things first like read a book, browse Programming, Ruby, or Elixir subreddits, Hacker News, Indie Hackers.
- Wasn’t able to get to the React part of the day, but I’ll do it tomorrow.
- Hashicorp: Created Vagrant (that’s why it sounds familiar!), Vault, Terraform.
- I just moved lifelong-learning to a private repo, because of the copyright work commits.

AWS: The 10K Foot Overview.
- AWS Global Infrastructure
- 16 regions, 44 availability zones. 6 more regions/17 more AZ’s for 2018.
- You will never be tested on numbers, etc. No rote learning.
- Region: geographical area.
- Availability zone: data center. They can survive natural disasters. At least 2 per region.
- NA: US E (N Virginia), US W (Oregon)…
- Edge locations: endpoints for AWS which are used to caching content. Typically, this consists of CloudFront. These are cached from physical locations close to the request.
- EC2: Virtual machines in the AWS platform.
- EC2 container services: where you manage Docker containers at scale.
- Elastic Beanstalk: These provisions scalers, load balancers, etc, so focus just on the code.
- Lambda: You upload and you wait for it to execute. Nothing to manage. All you worry about is your code.
- Lightsail: Amazon’s VPS service. Provision you a server, a fixed IP address you can log in the server from, and it will give you SSH access/admin panel.
- Batch: Batch computing in the cloud.
- S3: Simple Storage Service, object-based, you have buckets, upload these in the cloud.
- EFS: Elastic File System, network attached storage. We can put files in EFS and mount them onto virtual machines.
- Glacier: Data archival.
- Snowball: a way to bring a large amount of data into the data center. Like literally a physical box.
- Storage gateway: Virtual machines that can replicate themselves onto the AWS cloud.
- RDS: Relational database service. Anything.
- DynamoDB: Non-relational database.
- Elasticache: Stuff like “top 10 products”.
- Red Shift: Data warehousing/business intelligence. Complex queries.
