AWS Certified!

AWS Certified!

I’m grateful to announce that I am now a Certified AWS SysOps Associate! Over the past few months I’ve been studying intensely for the exam several hours a day. The positive side of this is that I now hold a wealth of practical knowledge about how to use AWS across a broad number of AWS services. The drawback is that I’ve not had time to work on my personal AWS projects, but I intend to pick back up on that…

WordPress Continued: How to Migrate Assets to AWS S3 And CloudFront

WordPress Continued: How to Migrate Assets to AWS S3 And CloudFront

So in my WordPress experiment, one of my goals has been to create a fully scalable WordPress site that can be scaled up (increase host resources) and/or scaled out (increase number of hosts). To do this, our core WordPress hosts must be stateless. By that I mean that, for example, my stored images cannot be different on one host than another. Otherwise, users will get inconsistent experiences. The solution to this is to store all of our assets (css, images,…

Subnet and VPC Gotcha’s When Using An Elastic Load Balancer

Subnet and VPC Gotcha’s When Using An Elastic Load Balancer

So I’ve successfully migrated this site to a load balanced environment using an Elastic Load Balancer. There are a couple “gotcha’s” that I ran into while doing this, and I want to jot them down before I forget: I wanted to create multiple subnets for a load balanced environment across availability zones, but since my original subnet was the same size as my VPC (e.g. 10.0.0.0/16 = 10.0.0.0/16), I had no IP ranges left to create new subnets. So to have multiple…

Oops! Creating AMI’s Shuts Down Services

Oops! Creating AMI’s Shuts Down Services

So this afternoon I was playing around with creating AMI’s. After I created an AMI based on the EC2 instance hosting this website, the website went down. When I logged into the instance I found that Apache wasn’t running. After some quick searching, I found out that during the AMI creation process, services are stopped unless otherwise specified. And I had made the rookie mistake of not setting the run level for the httpd service so that Apache would start up…

New AWS Feature: EC2 Screenshot

New AWS Feature: EC2 Screenshot

I just learned today that AWS has a new feature for Amazon EC2. It’s called Instance Console Screenshot. From the AWS website: Instance Console Screenshot provides an on-demand screenshot of the instance console, conveying valuable debug information. This capability is particularly useful when diagnosing instances that have become unreachable via RDP (Windows) or SSH (Linux) due to in-progress software updates, VM Import issues, or other blocking system events. Screenshots can be viewed in the AWS console or accessed via the AWS…

Installing WordPress

Installing WordPress

One of the most recommended exercises for learning AWS is the installation of a working WordPress site. This exercise appealed to me in particular because I have a strong background with WordPress development, so it is a technology very familiar to me. I also decided that as part of this exercise I would utilize Route 53 to register a new domain name, and then point my new domain to WordPress installation. A number of steps I implemented used this helpful…

First Post

So as the blog title suggests, this blog is more or less an experiment and log of my journey into the world of cloud computing. Currently I’m on course to take the AWS SysOps exam in a couple of months. Meanwhile I am using various study sources to prepare, including acloud.guru, Cloud Academy, Linux Academy, as well as a book titled “Amazon Web Services In Action” which seems very promising. Even though I’m taking the SysOps exam first, I’m going…
