How Useful Did You Find Git and GitHub?
-
Essential
Once you begin to work with Git you cannot imagine making it in the old way. Any software project in the world is supporting their software flow over CVS such as GitHub, GitLab, Bitbucket. So is very useful and needed.

A technology that unites ideas
The great power that tools like Git and GitHub have is making it possible for different ideas and even ways of thinking to come together on a project. Seeing the results of a collaborative process is one of the most rewarding experiences a team can have and this technology makes it possible.

A great tool for developers working in a team
Github has been a a great tool for me now that I'm working in a team. All I need to do is to push my changes and pull my my teammate's changes to merge the project. I'm not scared to lose my project because all my changes are saved on my repository

A true collaborative source control technology
Git is very easy to use and GitHub has made it easy to use it for personal, enterprise and community projects. Git has plenty of GUI tools and it can be integrated into any modern development and deployment environment.

A remarkable technology
Git and GitHub has being a technology I have always wanted to learn. My tech friends always used it and I felt, I was missing out. I finally get to learn it and it seems I am more better than my friends as I use terminal or git bash to run my git commands effectively. I am thankful to Udacity and Bertelsmann for giving me this opportunity to learn about git and GitHub.

The heart of open source
A handy tool which is an important skill for all developers to learn in order to work collaboratively. I personally use it & find features like logging history, reset, pull, rebase, merge, cherry-pick, etc. useful in my project collaborations.

Git has become a life Saver
For me git has become a life saver and an important part of web development. With differing levels of experiences by developers in team, and the constant feature updates requested by the clients; git really saves the day when something gets deleted by mistake; or the client ask to return a feature, that they gave an approval for deletion just two weeks ago. Additionally its always good to have a history of file changes to refer to.

README First!
Creating a well defined README file, Encouraging collaborators to always consult the README's before making changes and PR is a valuable skill of an efficient project.

Better Than TFS
Git and GitHub was my favourite area of the course. While learning the open source technology I compared this to standard TFS, my decision is I now prefer Git and GitHub due to the branching and excellent logging methods. In addition, I can apply Git to my personal projects as using TFS would not be practical.

Quick and Easy To Learn
Git and GitHub was simple to learn than expected. It provides excellent tools such as branching off to avoid damaging the main project when making changes before merging the differences back together.

AWS Shield
AWS Shield is a dedicated service to mitigate against distributed denial of service attacks. It is available in two tiers: standard and advanced. The standard tier is available automatically for all resources consumed or provisioned on AWS at no extra cost. It protects against common attacks. The advanced option further provides WAF and Firewall Manager at no cost and protects against more advanced attacks. It also has a feature for billing and cost control.

AWS S3
AWS S3 is the object storage solution from AWS, wich allow its users to create places where they can store they objects (images, documents, etc.). This is charged by the size of the information you are storing there and also determined by the frequency with which you will be accessing the information, you can see more here.
You can use your bucket for store information or even to server static websites like this.By Javier Arboleda. Feb 14, 2020

Elastic Block Store (EBS)
Elastic Block Store is a storage solution for EC2 instances, a physical hard drive that is attached to the EC2 instance to increase storage. When an EC2 instance is shut down, persisting of data is acheived by means of the Elastic Block Store so any data stored on the volume is still accessible. Likewise each amazon EBS volume is automatically replicated within its AZ, this protects against component failure thereby offering high availability and durability. These are just a few of the benefits that comes with the Elastic Block Store.

Elastic Container Service(ECS)
ECS is an orchestration service for automating deployment, scaling and managing of your containerized applications. ECS works well with Docker containers by launching and stopping docker, scaling your application and querying your applications.

Cloud computing with AWS EC2
Elastic Cloud Compute or EC2 is a service that provides servers for rent in the cloud. It is not considered serverless. There are several pricing options according to the desired configurations and necessities. Elastic Load Balancing automatically distributes incoming application traffic across multiple servers. It works with EC2 Instances, containers, IP addresses, and Lambda functions and you can configure Amazon EC2 instances to only accept traffic from a load balancer.

Simple Queue Service (SQS)
Queues are one of the most important data structures. They allow for asynchronous communication between different systems, and are especially useful when the throughput of the systems is unequal. AWS provides two variants of sending notifications via SQS:- 1) Standard - higher throughput, with “at least once delivery”, and “best effort ordering” 2) FIFO (First-In-First-Out) – not as high throughput, but guarantees on “exactly once” processing, and preserving the ordering of messages. In summary, if you need things super fast, can tolerate messages out of order, and possibly sent more than once, Standard queues are the answer. If you need absolute guarantees on order of operations, no duplication of work, and don’t have huge throughput needs, then FIFO queues are the best choice.

Virtual Private Cloud (VPC)
Amazon Virtual Private Cloud (Amazon VPC) provides a logically isolated section of the AWS Cloud where a AWS user can launch resources in a virtual network. User can create a public subnet for his web servers that have access to the internet. He can also place backend systems in a private subnet with no internet access. Security groups and network access control lists helps control access to Amazon EC2 instances in each subnet.

Simple Storage Service (S3)
Simple Storage Service (Amazon S3) is an AWS object storage service. It offers scalability, data availability, security, and performance. Amazon S3 is designed for 99.999999999% of durability, and stores data for millions of applications for companies all around the world.

CloudWatch
CloudWatch is a metrics repository available in AWS. An AWS service puts metrics into the CloudWatch repository and the user can retrieve statistics based on those metrics. If user puts his own custom metrics into the repository, he can retrieve statistics on these metrics as well. Metrics is used to calculate statistics and then present the data graphically in the CloudWatch console. User can also configure alarm actions to stop, start, or terminate an Amazon EC2 instance when certain criteria are met. Furthermore, he can create alarms that initiate EC2 Auto Scaling and SNS actions.

EC2 Server
The benefit to using Amazon EC2 servers is the ability to increase or decrease the number of server instances within minutes. You could not achieve this speed when managing each physical server on premise. Imagine a scenario, where a customer is complaining about poor performance due to the instance, you could resolve this issue within minutes instead of days or even weeks.

Relational Database Service (RDS)
RDS will allow you to create, operate and maintain a relational database within the cloud. The simple scalability feature provides database administrators cost effective solutions and can automate time consuming tasks.

My Personal Private Internal System
As geeky as this could be, I would develop and deploy my own internal system which I can access from anywhere when required. The web application will require user authentication to prevent rogue users accessing it. This system will be developmented to personally benefit my general life by the use of data.
