Docker Containers: Getting An Image

I will be working with Docker running on Windows (although sometimes on Linux). Docker appears to be the most popular and has a strong standard. You can go here to get the appropriate Docker installation. If you are unfamiliar with what a container is or why they are used Docker has a great explanation here. Basically, a container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another. A Docker container image is a lightweight, standalone, executable package of software that includes everything needed to…

Docker Containers: Why?

Since discovering Docker, I rarely find my self directly installing software on my computer or home lab. Whether is it a database server (Microsoft SQL Server) or I am just wanting to explore something new  I try to find or build an appropriate Docker image. Installing software is not hard, however using Docker saves time and provides consistency by reducing the task of installing and running software to just two commands (docker run and docker pull). In my next post I will show this process in action by taking a step by step look at how easy and simple it…

CCNA Routing and Switching Updated

Cisco is announcing updates to its most popular certification, CCNA Routing and Switching which will enable customers to fully benefit from the power of Cisco’s latest technologies. The role and skills required of a core network engineer will evolve significantly.  Through these next generation training and certification offerings, IT professionals will be able to demonstrate to hiring managers that they are ready to design and deploy the best in industry solutions. The CCNA R&S certification has been updated to meet these latest shifts in technologies.

Update: CCNA R&S Studies #2

Nibble, nibble, that’s all I can do. While I do not find the CCNA studies hard, I find I must nibble on networking technology a little at a time to better digest. SO, I’ll be going slow with this and only studying it lightly. In the meantime, I’m going to be studying MTA: 98-365 Microsoft Windows Server Administration Essentials to get it completed. This will allow me to move to the areas I find exciting; MCSA and then onto MCSE: Private Cloud. While I do not back down from a challenge, I realize the gains from studying something I’m enthusiastic…

The Cloud is big business

The Cloud is big business International Data Corporation (IDC) predicts by 2016, there will be an 11% shift of IT budget away from traditional in-house IT delivery, toward various versions of cloud computing as a new delivery model.  By 2017, 35% of new applications will use cloud-enabled, continuous delivery and enabled by faster DevOps life cycles to streamline roll-out of new features and business innovation. Source: 2015-2017 Forecast: Cloud Computing to Skyrocket, Rule IT Delivery. By 2018, IDC forecasts that public cloud spending will more than double to $127.5 billion. This forecast is broken down as follows: $82.7 billion in…

CCNA in 60 Days – maybe not…

Now that I’ve picked up a Microsoft cert using a desktop technology, I am moving to learn more about networking to continue building a strong knowledge base. I originally intended to begin my CCNA studies using the CCNA in 60 days method (buy the book here). However, I do not like to rush myself to learn a technology, or concept; I’m learning, not cramming to pass. There’s a big difference to me. So, while I’ll be reading it to supplement my studies, I’ll only be using it as such.
