“This is the first article in a three-part series on managing LAMP environments (Linux, Apache, MySQL, and PHP) with Chef (a configuration management tool).
The series covers using Chef to provision a development environment on a virtual machine with Vagrant and VirtualBox, and a production environment in the cloud with Amazon EC2. Prior knowledge of how to manually configure a LAMP stack is assumed–this tutorial shows how to automate the process, but doesn’t explain the configuration options in any detail.”

Don’t Automate What You Don’t Understand
“Automation is a noble goal, but in order to automate anything you have to have visibility and understand what you have. A common misconception for enterprises commencing their automation journey is that the key preparation work is choosing a tool and training their staff up. The real work is actually gathering requirements. With legacy and hybrid infrastructure in play what matters most is getting visibility of current state to
take control of the chaos.”
“The relationship between central IT and developers is being re-defined as the world adopts cloud technologies. The ultimate challenge is making central it feel secure while simultaneously giving developers freedom. IT wants to be able to control the deployment of applications so that there is consistency and adherence to policy. The policy could be related to PII or even the size of the VM that will host the application. There could also be cost considerations as well as monitoring and performance. Developers want to focus on their applications, their code. Developers don’t want to worry about public versus private cloud or with finding exactly their app should be installed.”
As brands start to commit themselves to content marketing programmes that are as deep and enduring as any major publication, inevitably questions arise about the merits of curating and republishing content that has not been authored by the brand.
But what is curation and why are brands curating ‘content’ in particular?
In layman’s terms, curation is the collecting and ordering of things for a particular intention or experience.
Ambition: “As a manager or chief executive you want people alongside you who are going to share your hunger,” Caan says. “Otherwise it is impossible to build the successful company you envision.”
Initiative: “The simple fact is that every manager wants workers who have the initiative to organize their workload and go about their business without the need for constant supervision,” he says.
Commitment: “Someone who is prepared to stick at it even when times are tough,” says Caan, “and who will go that extra mile for themselves and the company is a huge asset.”
Personality: “It is becoming increasingly difficult to stand out in the modern world, so someone who has a little bit of personality can make a big difference to the atmosphere in the workplace,” he says.
“Many candidates go into interviews and are keen to emphasis their skills,” Caan says. “This is fine, but if you can also show potential employers you have most of the qualities listed above — preferably with examples — you will almost certainly become a more attractive candidate.”

Some Salt for that Heartbleed — SaltStack.
Saltstack is another automation and orchestration tool much like Chef and Puppet. The latest attack vector, heartbleed, is exploiting an OpenSSL vulnerability. OpenSSL has been remediated and now it is the sysadmin and devops job to apply the latest OpenSSL update to all their servers. To do this, using salt, they simply execute pkg.install openssl refresh=True; This single command can be used to remediate entire datacenters in less time than it takes to make a cup of coffee. Very, very powerful.
Docker is red hot at Red Hat | DevOps.comDevOps.com.
Great news for early adopters of RedHat’s OpenShift. Docker will allow portability of an app from start of engineering to full-scale production. Great concept that continues to repeat itself over time.
