Docker, its advantages and security issues

Recently, Cloud computing represents an attractive and cost-efficient of server-based computing and application service provider model. Virtualization technology not only enables Cloud providers dynamically allocate resources based on workload fluctuations from users’ needs but also makes the cloud data-center more agile, manageable, cloud friendly and application friendly. However, virtualization has overheads of the guest operating system, costly licensing for virtualization software, configuration and administration time, etc. Docker, as a solution, is emerging in the technology circles and is rapidly gaining mind-share from researchers, developers, startups and IT organizations. As a matter of fact, Microsoft, Google and Amazon Web Services are all adapting Docker’s approaches so as to provide their services more efficient, and to scale their resource workloads ever-higher to cloud customers.
In this post, we study about what Docker really is, how it works, its run-time, orchestration and then discuss about Docker’s advantages, disadvantages. We will go to an end with Docker security in Cloud environment perspective.

2016. Time to start blogging again

It has been 4 years since my last post. The Earth still rotates itself from the West towards East and travels around the Sun but this world has been changing a lot within 4 years.

I started this blog from August 2008 when I was 21, an undergraduate student who was eager to learn and explore this world through the Internet. Since then, I have about more than 100 posts and they are mostly in Technology category.

During my graduation school, I only focused on paper works and research. That was a really tough time since I had to spend whole time of a single day to go in depth into topic of research as well as to publish enough publications for my graduation. As a result, this blog was like in Ice Age time period 😆 but the good thing is, I have never put it down since 2008. You can find out my very first post (probably at the same time as mammoth’s birth) up to now.

This world changes, so do I. From now on, I am planning to blog more frequently. And the topics, of course, will be mainly (90%) in Tech’s topics such as Cloud Computing, Big-data analysis and Programming; the remaining 10% of posts are for personal stuff and some shite. :mrgreen:

It’s time to start blogging again.
