SuSE Enterprise Linux continues to be a favourite in larger organizations.

A slower release-cycle, consistent longstanding interfaces and YaST management prove to be favourable to systems custodians.

Let's have a glance at the latest incarnation of SLES Enterprise Linux..

The latest major version of Debian GNU/Linux includes updates to key libraries, packages and bundles.

Cloud Images abound on your favourite platforms. Hassle-free, long-term Security Updates endure, resulting in the ability to easily incorporate this popular Distro. Have a go with some Instances and consider Debian for your App environment.

Let's explore Administration of this release, with a Cloud-Focus..

In the peer-to-peer distributed era, DNS remains the most-critical glue in application stacks, ensuring proper routing of traffic.

Cloud-DNS offers various logical algos to assist with proper distribution, virtually eliminating single points of failure and superfluous latency.

Use AWS Route53 to aptly respond to DNS requests for your Apps and Services..

(In|Out)ward Scaling, pre-Cloud Elasticity, has been a bane to those in the decision and execution pipeline. Scale too widely, there is waste; the converse fails to meet demand, potentially resulting in displeased constituents.

As there is an App for most things, there is a facility to meet this challenge. The ability to automogacially scale (In|Out)ward in order to maintain a formidable Fleet and to meet user-demand.

Let's peruse AWS Auto-Scaling Groups of EC2 Instances in this release..

Integral to a scalable Cloud experience is a proper topological design. Modus Tollens appears to NOT apply to this realm of Computing considering its ample room for Development | Staging | Production.

Virtual Private Clouds (VPCs) offer Software Defined Networking (SDN) of common , but key, Infrastructural components largely premised on EC2 Instances and their derivatives of all incarnations, in a distributed and potentially highly-available and pleasingly resilient, and, salubrious form.

Let's examine the AWS VPC-Defaults, and, re-orient the layout to mimic familiar Corporate architectures..

High-Availability (HA) of Web-facing Apps is par-for-the-course in the current commoditized computing environment. Open Source components à la HAProxy bring considerable economies of scale to HA theatres, resulting in high-performance and minimal down-time.

AWS Elastic Load Balancing (ELB) service offers simplified L[47] HA for your Cloud Apps. Use it to increase availability and performance as needed. Also factor AWS ELB into your DR | BC action-plan.

Let's peruse key components of AWS ELB..

The Cloud, as a Platform, and Software Defined Networking (SDN) offer considerable value for all manner of applications. From concept through production deployment, it has never been easier to quickly instantiate resources on-demand, at dynamic scale, in order to test ideas and develop useful solutions.

Let's peruse key components of AWS EC2..

Standard across Scripting Languages is the ability to parse data based on classic Perl Regular Expressions (RegExes). Python is no exception with ample Perl-Compatible RegEx support.

Let's parse some data with Python RegExes..
