Q&A: Why Union Bank scrapped AIX for Red Hat

Filed under
Interviews

As Linux establishes itself as a mainstream operating system, and open source tools and applications prove their enterprise readiness, a growing number of organizations are talking publicly about their open source deployments and direction. Recently, Mok Choe, CTO at Union Bank in Monterrey Park, Calif., spoke with Network World Senior Editor Jennifer Mears about the financial institution’s decision to scrap proprietary Unix systems for commodity servers running Red Hat Linux.

Give me some background on your move to Linux and open source.

We were faced with having to do an upgrade of our Web infrastructure last year, which gave us an opportunity to really look at our architectural direction. We decided to head in the direction of horizontal scaling using commodity hardware and open source tools. There are multiple drivers behind this thing. Cost is clearly one of them. First and foremost always is the reliability and performance. The second thing is we wanted to be able to scale much easier than we do today. Since we run on big boxes, at some point to scale you have to buy another big box. Instead of that, we wanted to be able to rapidly manage capacity by adding or subtracting commodity hardware.

Had you been using any open source software previously?

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
