AWS info

Virtual Servers
● EC2- the classic, the original. Virtual servers on shared
hardware similar to VMWare. General purpose computing.
● Associated services: Auto Scaling Groups, Elastic Load Balancers
● Container services:○ECS - Elastic Container Service
● EKS - Elastic Kubernetes Service
● Fargate - Serverless Containers
● Lightsail - actually EC2's but simple as heck

Code As A Service
● Lambda - executes individual functions (in a variety of
programming languages) on an ad-hoc on-demand basis and
you pay by the millisecond of elapsed compute time○Go, Rust, Java, .NET,
Python, Node, Ruby, or custom runtimes
● The glue that holds AWS together○Dozens of other services have “hooks”
such that “when XYZ event occurs, run this Lambda”
● Little code snippets can augment your S3 buckets, Cognito user pools,
SQS queues, and so many more

Bundling Services That Deploy Applications
With Compute Under The Hood
● Elastic Beanstalk - upload application packages and it
provisions Elastic Load Balanced, Auto Scaled EC2 groups to
serve them
● App Runner - similar to Elastic Beanstalk, but simpler
● OpsWorks - a puppet/chef approach
● Some CodeStar templates

Developer Tools
● Cloud9 - A web-based IDE similar to Visual Studio Code, hosted on EC2s
● CodeCommit - Distributed source version control, analogous to
Github/Bitbucket
● CodeBuild - Automated builds when commits arrive in CodeCommit
● CodeArtifact - Saved generated assets when Codebuilds complete
● CodeDeploy - Automated deploys when CodeArtifacts are available
● CodePipeline - Marries a CodeCommit, CodeBuild, CodeArtifact, and
CodeDeploy together into one seamless pipeline that creates an entire
CI/CD system analogous to Circle, Travis, Jenkins
● CodeStar - Marries all six of the above into an all-in-one factory where
you edit the source code in the browser in Cloud9 and it deploys as you
go Inter-Service Messaging
●SNS - push-style notifications that connect any number of Message Producers
into a Topic that are pushed to Subscribers
● SQS - pull-style notifications that connect any number of
Message Producers into a Queue that is then polled by
consuming processes for the front N items○Includes Visibility Timeout
and Long Polling
● SES - transactional email service

Identity Management
● IAM - Identities internal to your AWS account○Users
● Groups
● Roles (both machines and people)
● Policies
● Deny-first except in case of role assumption, use principle of least
privilege
● Cognito○Identity management for Applications, providing secure username
and password management,
single-sign-on, social sign-ons. Analogous to Auth0 or Okta

Networking
● VPC - a Virtual Private Cloud. A private CIDR (IP address range)
(e.g. 10.10.*.*) that you set aside for your devices to span, within
which network traffic belongs to you.
● Every account has a VPC by default, even if you don’t remember
configuring one!
● Subnets - specific subsets of VPCs that live inside a single availability
zone
● Network ACLs - Access Control Lists for the traffic inside VPCs
● Route Tables - Directs traffic to specified IP ranges to specific network
hardware such as Internet Gateways and NAT Gateways
● Internet Gateway - Enables two-way traffic in and out of a VPC with public
IPs
● NAT Gateway - Enables one-way traffic out of a VPC without exposing the
devices whose traffic is being routed through it
Networking, Continued
● Cloudfront - Global CDN similar to Cloudflare. Provides
“edge locations” in most major metro areas where content is
cached to be closer to client requests. Can do lots of cool
things with Lambdas.
● Route 53 - DNS service. Can register and buy domains as well
as administer their nameserving. Similar to GoDaddy.
Storage
● S3 - Simple Storage Service. Technically a key/value store, but
where the values are typically files (can be any data). Puts
“objects” in “buckets”. Can be connected to Lambdas to do
cool things. Several storage tiers available.○Standard, Infrequent Access,
Glacier, Intelligent Tiering...
● Snowball - hardware for transferring up to 80 TB of data in
one chunk from your location to an S3 bucket, through
physical drives
● Snowmobile - armored truck of snowballs for moving
petabytes of data to the cloud

Salt -- cheat sheet

      The Salt system is a Python-based open-source remote execution framework for configuration management, automation, provisioning and orchestration.  A basic Salt implementation consists of a Salt master managing one or more Salt minions.

Euro trip. Chapter1: Bucovice-Prague-Nuremberg-Leipzig-Dresden

    Begin to write something every time is complicated for me. Any way i should start. So this trip was somehow unplanned. Where to go, stay ... everything planned on way.    Trip started 2nd of July from Bucovice to Prague. Made reservation on "Hotel Globus" for one night. After check-inn we went to centre walk, see landmarks  of Prague. Additional we have a lunch at asian cafe.     3rd July. Next our plan was drove from Prague to Munich stay one night in camp hostel, visit Munich Zoo. But plans changed on way and we decided drove first Nuremberg to see my friend. Made reservation at "Azimut Hotel". As we arrived earlier check-inn was after 3PM, parked car and we decided not to waste time go and see Nuremberg. We have a lunch some soup and german sausage. And also for 30 euros we took city tour by bus about 2 hour. We saw almost whole city with information (recommended). Evening we meet my friend have a lunch thanks special thanks Fagani.
