Class Introduction

Welcome to Compute Engines in Amazon Web Services

We strive to create a learning community here — one where you learn from myself, the material and your fellow students through engaging and educational activities each and every week. Although we cannot be physically together, we can still create a feeling of connection to each other through a shared experience with the assignments, labs, and discussions. Here, you along with everyone else in class are valued members of this learning community. During this Covid-19 life we are living, there are additional challenges and responsibilities in life to family, friends and work. Sometimes, because we are human, we can get sick or just become overloaded. So, if you have reached a point where you can’t meet an assignment deadline, please contact me–we will work together to make a path to success. We are in this together.

If you are a student with a disability, please do not hesitate to let me know at the beginning of the semester, if you like to. You can access the Student Services Online for assistance; access to campus is closed due to the pandemic. The telephone number there is (818) 722-6752.

If you have any questions or concerns, please reach out to me. I am here to help. The best way to contact me is through Canvas Private Message (Inbox). I will get back to you within 24 hours, Monday thru Friday. Over the weekend it might be 48 hours.

I am excited to be guiding this class, I love working with Amazon Web Services and I hope you will, too.

Class Description and Overview

This course introduces AWS (Amazon Web Services) computing related services. Students will learn about the core computing services offered by AWS. The computing services will follow the computing models: Infrastructure as a Service, Platform as a Service, Function as a Service or Micro-services and server less computing (Lambda functions). Students will set up and manage computing services, configure auto scaling and load balancing. Students will learn to code auto deployment scripts to automate the management of AWS infrastructure.

 

 

Introducing the Instructor

Hi, I’m George McKinney, a Software Developer based in Los Angeles. For 15 years, I have worked on projects for many companies including Acura, Disney, Samsung, LG, Kraft and numerous medium-sized firms and startups. My journey as a professional developer began at Los Angeles Community College where I studied C/C++, Java and Macromedia Flash. I learned computer science and applied it in marketing, sales, automation and communication solutions. I absolutely love what I do and sharing it. As I became more experienced, I went from attending workshops and conferences to presenting at them. I co-founded a mobile user group, organized meetups, conferences and travelled the world for “fun and profit.” Along the way, I taught software for the US Navy, City National Bank, Starwood Hotels, Stanford University, Cisco Systems, Lawrence Livermore National Laboratories, and other places. I have an MBA from the University of Southern California and my undergraduate degree was in History at Stanford University.

Nine years ago, I started using Amazon Web Services because I had heard something about Cloud Computing and I thought I could use it to put a website on it… something about S3 and a lot of EC2 and I figured I should have a look. At the time, I wasn’t much interested because mobile apps was in high gear and I focused my attention there. Five years years later, I began to see more job announcements come out requesting AWS from companies like Disney, Fox and others and I told myself to pay more attention to this. Around the same time, I got an Amazon Alexa and discovered that it was programmable and I was hooked. I reopened my AWS console and saw cobwebs on my S3 buckets and went straight writing Lambda functios with Node.JS and I haven’t looked back. Today, I work on large value projects building call centers, event rooms and communications platforms. I feel great when I see my work in people’s hands.

Accommodation Statement for Students with Disabilities

The college and I are committed to your success here in this course. If you were not already aware we have resources described below for you. Please contact me if I can be of help or you need accomodation.

Disabled Student Programs and Services (DSP&S)

If you are a student with a disability and require classroom accommodations, please contact me to discuss arrangements. The sooner I am aware that you are eligible for accommodations, the quicker I will be able to provide them. If you have not done so already, you may also wish to contact the DSP&S Office in Instruction Building 1018 (phone 818-364-7732 / TTD (818) 364-7861 ) and ask them to contact me with a letter stating the accommodations that are needed.

Students requesting academic accommodations should first contact them online or by email , otherwise use the following procedure:
Step 1: Obtain documentation of your disability from a licensed professional. You may contact DSPS to request a Disability Verification Form.
Step 2: Make an appointment to meet with a DSPS Specialist to review your documentation and discuss reasonable accommodations.
To schedule a meeting, please call DSPS at (818) 364-7732.

WordPress Canonical URL, Permalink Redirect, ERR_TOO_MANY_REDIRECTS

Filed under: Apache,WordPress — georgemck @ 3:22 pm

WordPress uses .htaccess to automatically attempt to correct URLs that are misunderstood. This behavior can lead to errors such as ERR_TOO_MANY_REDIRECTS and prevent intended funcationality such as using an index.html as a landing page for the domain. It is possible to Disable WordPress Canonical URL or Permalink Auto Redirect to fix these problems.

 

This code snippet can be placed at the top of the theme’s functions.php file:

remove_filter('template_redirect', 'redirect_canonical');

AWS Shell Java Install

Filed under: AWS — georgemck @ 3:05 am

You can switch between versions with sudo

from https://tecadmin.net/install-java-on-amazon-linux/

 

Step 1 – Install Java on Amazon Linux

The OpenJDK 8 is available under default yum repositories and OpenJDK 11 is available under Amazon Linux 2 extras repositories. You can simply install Java 11 or Java 8 on the Amazon Linux system using the following commands.

  • Run below commands to install Java 11 on Amazon Linux: 
    sudo amazon-linux-extras install java-openjdk11
  • Run below commands to install Java 8 on Amazon Linux: 
    sudo yum install java-1.8.0-openjdk

Step 2 – Check Active Java Version

After successfully installing Java on Amazon Linux using the above steps, Let’s verify the installed version using the following command.

java -version

openjdk version "1.8.0_222"
OpenJDK Runtime Environment (build 1.8.0_222-8u222-b10-1ubuntu1~18.04.1-b10)
OpenJDK 64-Bit Server VM (build 25.222-b10, mixed mode)

Step 3 – Switch Java Version

Use alternatives command-line utility to switch active Java version on your Amazon Linux system. Run below command from the command line and select the appropriate Java version to make it default.

sudo alternatives --config java

Install Java on Amazon Linux

After switching let’s check again active Java version:

java -version

openjdk version "11.0.7" 2020-04-14 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.7+10-LTS)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.7+10-LTS, mixed mode, sharing)
