Source of Truth

"Imagine walking down the park with your wife, and suddenly seeing your ex. Wife talks automation, she agrees. Wife says intent, she does the same. Wife talks container... and now they are best friends forever."

Since Cisco and Google announced a partnership to deliver a hybrid cloud solution last year, I started following back to see what my ex is doing in software space. During my time in Cisco it used to be a hardware-first company, or a "software solution that must run in own hardware"-first company, so it is interesting to hear about the announcement of Kubernetes-based Cisco Container Platform recently. It is great to see new materials from Cisco DevNet to transform the skills for Network Engineer towards software-based and automation, just like this awesome Network Programmability Basics video course.

One blog post by Hank Preston about "Network as Code" caught my attention. He laid the three principles of Network as Code: 
  • Store Network Configurations in Source Control
  • Source Control is the Single Source of Truth
  • Deploy Configurations with Programmatic APIs
and now I would like to expand more about this Source of Truth, in the context of network device config generation.

There’s still a lot of life left in tape backup

This industry likes to abandon technologies as soon as it adopts them, but a few find a way to hang around. I recently purchased a car, and in the finance office was a dot matrix printer, chugging away at the same multipage forms I saw used more than 25 years ago.Tape backup is also hanging in there. With data being produced in ever-increasing numbers, it has to be stored somewhere, and hard drives aren’t enough. For true mass backup, enterprises are still turning to tape backup, and the LTO Program Technology Provider Companies (TPCs) say 2017 shipments grew 12.9 percent over 2016 to 108,457 petabytes (PB) of tape capacity.Read also: The future of storage: Pure Storage CEO Charlie Giancarlo shares his predictions | Sign up: Receive daily network news updates LTO TPCs is a group consisting of three tape backup providers: HPE, IBM, and Quantum. There are other tape backup providers, such as Oracle, which inherited the StorageTek business from Sun Microsystems and still sells them, but it was not included in the count.To read this article in full, please click here

5 years later, Docker has come a long way

The evolution of Docker: From introducing a container runtime to building an enterprise-ready container platform

Back in March 2013, Docker was introduced publicly for the first time during Docker founder, Solomon Hykes’ lightning talk at PyCon. Since that moment in 2013, Docker has evolved in conjunction with the needs of users and customers to drive innovation around security, orchestration, networking and more. From building out advanced security features across the software supply chain and offering the choice of both Swarm and Kubernetes, to developing Docker for Mac/Windows and the Docker Enterprise Edition (EE) container platform, Docker has come a long way. Now at the age of five, Docker has millions of users and over 450 commercial customers – including hundreds of the world’s largest companies – that rely on Docker EE to power their digital and multi-cloud initiatives.

Docker Birthday

The history of Docker has shaped where we are today and as we celebrate our 5th birthday this week, we take a look back at the journey that lead us here.

Following the enthusiastic reception at PyCon 2013, Docker’s image format and container runtime quickly emerged as the de facto standard and building block for the community, customers and the broader industry. The Continue reading

IDG Contributor Network: Say goodbye to spring cleaning

As spring finally rolls around and the frost melts away (except here in New England), the change in seasons not only brings us ultraviolet B-induced vitamin D, but also shines some healthy sunlight on the clutter the long winter leaves behind in its wake, including both at home and in the data center. With spring, comes an opportunity to reevaluate data center cleaning habits and question whether a more practical, day-to-day strategy would benefit data center managers in the long run.Instead of enduring the spring cleaning process in the data center, data center managers should rethink their current cleaning strategy, which often leads to seasonal operational overhauls, and instead consider a new and more efficient method that benefits from granular operational data and analytics. So, with the spring solstice upon us, here are a few tips to enable data center managers to reap the advantages of “year-round cleaning” rather than looking for that old and tired broom.To read this article in full, please click here

Restrictive networking is holding back digital transformation

CIO Magazine recently predicted that by 2020 there will be 4.1 billion internet users with 26.3 billion networked devices. This will cause data center traffic to jump 330%! Every industry is feeling the pressure to deliver innovative digital experiences to these network hungry consumers. This digital disruption is real — where speed, quality and agility mean everything to businesses. In fact, 40% of CEOs rank digital transformation as their top imperative, according to a recent Economist Intelligence Unit survey.

This means the vitality of the network is of the utmost importance to support the applications that we haven’t even dreamed of yet. Without a fast, agile Continue reading
