Docker Enterprise and what’s new in 2.1?

2018 was a busy year for the tech world, and this year looks to be no different, with Serverless and Containers expected to dominate mind-space in 2019. Docker has already started stepping up their game with the intention of redefining the experience of using Docker with a new Docker Hub that combines the Docker Store, Docker Cloud, and Docker Hub functionality in one place.

Writing smart contracts using Ethereum

In my previous blog, I discussed how you can build a simple Blockchain using Ethereum and Python on a Linux/Ubuntu box. Now that you are aware of a Blockchain using Ethereum, you may want to know about the next popular thing in the crypto space i.e. smart contracts. “What is smart contracts” has become one of the most-asked technology questions. So, let's talk more about smart contracts.

Rehashing re:Invent

The holiday season is a very merry time for everyone. You have Christmas to look forward to. And in addition to this, when it comes to late November, there is something else I have been looking forward to since 2012 (coincidently, I started my journey as a techie around the same time.) Yes, you guessed it right. I am talking about AWS re:Invent. Since its first edition, re:Invent has been an exciting conference for the computing community around the globe.

Kubernetes 1.13 is here!

Kubernetes’ final release for 2018 is here! This is the fourth release of the year and it comes just 10 weeks after the 1.12 release. Like the previous release, this release continues to focus on stability and extensibility. There are 3 major features that are graduating to GA in this release. They are Kubeadm, Container Storage Interface (CSI), and CoreDNS which is now the default DNS with every Kubernetes installation.

Let's take a quick drive through each of these new GA features.

Auto-healing MongoDB replication with Terraform

Data is the next big thing, and this has accentuated the importance of the way you manage your database. There are various operations that you perform with your database such as replication, partitioning, sharding, etc. These operations, most of the time, are not necessarily mutually exclusive. Database replication is one of the key operations when it comes to data recovery, fault tolerance, and consistency.

Building Skeleton Component with React and SCSS

Every developer wants to ensure the best performance for the application that is being built. Most of us concentrate more on technicalities when it comes to the performance of the application. Of course, that is the most important part of any application. But you often ignore a part of the performance called perceived performance. Perceived performance is nothing but how fast an action appears to happen to the user.

Create your own Blockchain using Python and Ethereum

Blockchain, as the name suggests, is a collection of blocks or data records chained together in a cryptographic fashion. Each block in the chain contains a hash of the previous block, timestamp, and transaction data, securing it from intruders/attackers and modifications in the future. This immutability is one of the most interesting features of the Blockchain.

Why you should be excited about Kubernetes 1.12?

I’m a bit late writing about this release of Kubernetes. It's already their 3rd release of 2018. Looking over the release notes and playing around with the new features is clear that the focus of the last release (making internal improvements) is continued in this release. The most notable features of this release are the support for Azure Virtual Machine Scale Sets (VMSS) and my personal favorite kubelet TLS Bootstrap.
