How To Use Hashicorp Tools To Create a Secured Edge Infrastructure

,

This article explains how to build a secure platform using HashiCorp’s stack; many of the steps are well documented, but we missed hints to iron out the wrinkles found in the process; here, we want to show how to glue together the whole procedure. We will highlight in detail the most critical parts explaining where we found issues and how we solved them, and leave references on the official tutorials, if sufficient, to prevent this article from getting too long and difficult to follow.

The Physical Architecture

As shown in the picture below, the physical architecture we want to achieve is composed of a Consul and Nomad cluster of five nodes: three of them are Control Plane nodes configured for High Availability (HA), while the remaining two are Data Plane nodes.

7 Tips to Achieve High-Availability(HA) For Your Maven Repository

,

Cloud Computing has emerged as a novel technology today. Every company is a software company today, and it is evident that no company can service without using the power of cloud computing. The cloud is seen as a conceptual layer on the Internet, making all available software and hardware resources transparent, rendering them accessible through a well-defined interface. 

As the companies are increasingly relying on these cloud computing services to be always stable and accessible whenever their customers need them, the services and applications’ downtime is highly unacceptable. In this article, we will be discussing the concepts related to high availability (HA), what it is, how it works, and how companies can take advantage of this.

Building a Mission-Critical Open Source Java Platform – Installing WildFly

,

In the previous article in this series introduced our thoughts on setting up a mission-critical open source Java platform using high availability in our Web layer. In this article we’ll continue by installing WildFly and configure our platforms topology.

Note: the terminology in this article, where possible, has been adjusted from the traditional master / slave descriptions to master / subordinate. Some of the images displayed have not yet been updated and show the older terminology.

Building a Mission-Critical Open Source Java Platform – The Web Layer

,

Currently the Java platform is one of the most consolidated in the world, much of this is due to platform’s ability to support other languages such as Kotlin, Groovy and Scala, etc. Thousands of web and mobile applications are developed using the platform as a base. The Java platform has changed a lot in recent years and probably will keep evolving.

In parallel with these changes, we see the evolution application servers, that increasingly offer highly complex features such as load balancing components, smart asynchronous messaging, transaction control and many other technologies facilitating application development and standardization. They also provide a stable and scalable infrastructure for mission critical applications. One of the biggest challenges for application servers is to couple highly complex services, making them stable and flexible.
