  • Improving the Standards of Linux Load Balancing and Failover

    Oracle supports both simple and weighted round-robin load balancing of requests from its web components and aims to improve features like high availability and load balancing. By following a specific path and port, Linux remote direct memory access (RDMA) has problems regarding performance and security perspectives. In the LDAP environment, load balancing for writes of a user and group data can produce undesirable behavior due to the replication. LDAP replication does not guarantee transaction integrity; the limitation of replication is however very dominant in the system itself.

    Segmenting the user and group data may be effective for distributing the load if the case rests upon separate user population in distinct branches of the Directory Information Tree (DIT). By maintaining different primary LDAP server for read and write purpose, load balances of such kind of operations can be obtained efficiently. Also, selecting a standard network interface card can be beneficial as they pick which network device is appropriate to transport the data. RDMA is proved to be more resilient over IP (RDMAIP) which creates a high availability connection to create a bonding group among adapters’ ports. The traffic automatically gets transported to the other ports in the group in case of loss of any significant port. This can be achieved by utilizing Oracle's Reliable Datagram Sockets (RDS).Oracle supports both simple and weighted round-robin load balancing of requests from its web components and aims to improve features like high availability and load balancing.

  • Linux Foundation maps out the telco’s future with edge and AI platforms

    The mobile operator no longer has the luxury of dealing with a relatively closed and well-defined set of technologies and partners. The mobile network is increasingly intertwined with fixed line connections, and also with broad virtualized, programmable platforms, which will be essential to enable new business models and justify the investment in 5G. That sees operators getting deeply involved in a host of new technologies and standards, and increasingly emerging from the secrecy of inhouse labs and working through open source projects. Two important areas of effort are edge computing and machine learning (ML). Both are the focus of several open initiatives, in which certain operators, notably AT&T, are prominent. Both are starting to be deployed, often starting with the…

  • Google infrastructure chief Urs Hölzle: This is the future of software and the cloud

    Look at the history of open source. Twenty years ago there was nothing that was relevant to an enterprise that was open source. Maybe BSD [Berkeley Software Distribution version of Unix], but basically nothing. Five years later, 2003, Linux and the LAMP stack [Linux, the Apache HTTP Server, the MySQL relational database management system and the PHP programming language] was pretty common already. Java wasn’t quite open source, but I’ll throw it in there. Basically, every five years afterwards, the amount of IT where open source was relevant was bigger.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
