There's been lots of new and exciting launches here at Linux Academy. In case you missed any of them, here they are:
Cloud Essentials is a basic certification through CompTIA. The certification aims to provide a vendor-neutral, conceptual understanding of the cloud. Cloud Essentials focuses on real-world issues and practical solutions for cloud computing, as it relates to business and IT. This is not a technical-heavy course and centers on the principles of the cloud, instead of the command line. CompTIA also has a CompTIA Cloud+ certification more in the direction of technical-heavy concepts that Linux Academy will offer in the future as well. If your organization uses the cloud or is still on the fence of migrating services into the cloud, the Cloud Essentials is a great starting point for you.
Microsoft Open Technologies has recently launched a service called VM Depot that allows you to quickly and easily scan for virtual machines. Correcting for one of the original pitfalls of Azure, the inability to quickly find a list of virtual machines, this new service puts this list at your finger tips - and Linux stands out!
Sometimes you need to host a static website somewhere. It might be a simple index.HTML page that you can easily redirect servers to in case of downtime for your current site or for simple documentation. How you use it is really up to you. But Amazon S3 now has the ability to "host" static HTML pages. This means that if you provide the link to your .html page the Amazon S3 bucket will think it needs to interpret that as a website and display it accordingly. This behavior is different than it used to be, Amazon would only allow you to download the object and not display it in a web page. Let's set up an index.html page in our Amazon S3 bucket.

Changing the partition size for a root partition or any other partition is just a little bit different when you're working in the cloud. Today I'm going to show you how to change the root partition of an EC2 instance running Linux. Resizing the root partition on an Amazon EC2 instance starts by stopping your instance.
S3cmd is a program that allows you to backup your Linux box to Amazon S3. Amazon S3 allows you basically unlimited storage and, as long as you have the bandwidth, you can use it from any location. There are two options in a backup that you can use: you can either copy all the files over to an S3 bucket (called put) or you can use the sync command to sync file changes on a regular basis.
If you've followed our Amazon Web Services screencasts then you are ready to install WordPress on your Linux server. First, we need to configure Apache2 to point to the correct root directory, download wget, check permissions on the server, create our MySQL databases, and finally install and run the WordPress configuration file. This screencast will help you solve issues you might come across along the way.
When first setting up an Amazon EC2 server, you receive an ssh key to connect to the instance. This article details how to use a PuTTY private key to connect to your Amazon EC2 Linux instance. Previously, we used ssh on the OS X terminal and our .pem key file in order to connect. However, that didn't work for our Windows users because .pem files are used with ssl (openssl). We will show you how to download all the PuTTY tools needed, create your private key, connect to your instance. We will also show you how to connect to your instance without an SSH key. The video included shows the practical application of the information written in the article below.
In this screencast you will learn how to create an image of your running amazon instance. You will be able to boot up new instances with the snapshot we learn to make in this tut.
