Easily Manage Your Build Environments With The Condo [Snippets]

,

Have you come across situations where your build tools suddenly stop working after you update the operating system? Do you want a simple way of setting up your build environment each time you change or format your machine?

One option is to use Docker-based build environments. In this approach, you can create Docker images with the necessary build tools and dependencies. However, you will still have to remember the tags, mount your source code manually, and execute Docker commands with multiple arguments each time. This approach is right but needs some effort.

Cloud Applications Require a Distributed Database

,

We are well past the experimental stage with the cloud. It’s become mission-critical, and we have entered a stage where our applications and services need to take advantage of the globally distributed nature of the cloud and deliver on the expectations of our consumers.

Legacy relational databases are simply not built for the cloud. They are difficult to scale in this environment and costly to maintain their uptime. NoSQL stores were built to address legacy limitations; however, they fall short when it comes to providing consistent transactions. They are casually consistent. Some of the most successful global organizations have purpose-built databases that achieve the reliability of the relational store with the benefits of scale and global coverage that comes with the cloud. These databases are a new breed called Distributed SQL.

How CentOS Became 2020’s Final Victim

,

If you were paying close attention to your IT department around the 8th of December, you might have heard some quiet sobbing and the occasional wail of, “Why? Why?! WHY?!” Now, it was the year 2020, so this might have seemed normal to you, but it’s actually something of a problem that could affect your business: CentOS is pretty much dead.

For the non-total-nerds among us, here’s the skinny: CentOS is a Linux-based operating system, typically used on servers. CentOS has been incredibly popular, and quite a few businesses run on it. But now, that’s changing.

CentOS is a Linux-based operating system, typically used on servers…But now, that’s changing

CentOS used to be released in thoroughly tested versions, the latest being CentOS 8. CentOS 8 was released in September of 2019 and was supposed to be supported for ten years. Now, it’s been decided that CentOS will no longer have versioned releases, opting for a rolling-release style of updates. That means there’ll be one version that constantly gets new software.

That’s cool in theory, but it means the operating system will be less stable overall. Essentially, it’s going to be used as a development branch of / testing ground for Red Hat Enterprise Linux and is no longer its own OS. If you have CentOS-based servers, you should migrate to another OS sooner rather than later.

And I just got my own CentOS-based VPS set up the way I wanted it.

Wait, What Does Red Hat Have To Do With This?

Here’s the short, short version of the history of CentOS: Red Hat (an OS developer) has two Linux distributions of its own and has had for a long time. There’s the free and community-focused Fedora and the business-focused highly expensive Red Hat Enterprise Linux (AKA RHEL).

Funny story: RHEL, despite its expensive licenses, is still mostly made from open source code, which anyone can access and use. And it’s a good OS, particularly for people who like stability.

In 2004, some smart people took all the open-source parts of RHEL and made a brand new, nearly identical operating system with it: the Community Enterprise Operating System, or CentOS. Basically, people could download and use an enterprise-level server OS for free. All the documentation for RHEL was compatible, and you could get support from the community.

It was the perfect alternative for anyone who didn’t have the budget for expensive software licenses.

In 2014, Red Hat offered to partner with the CentOS community. The idea was basically this: “It’s pretty much the same software. If our company and your community work together, both our products will be better! We make our money from enterprise customers, anyway.”

Most importantly, with Red Hat doing a lot of the heavy lifting in terms of updates and support, the CentOS community could focus on growing in other ways.

Red Hat pinky swore [citation needed] that they were in this for the long haul, and CentOS did continue to flourish. You know, until 2020.

Well, So Much For Pinky Swearing

Red Hat must have eventually decided that having a popular free version of its own enterprise software and managing it themselves no less — wasn’t that good for business. So they all but shut the project down.

Well, technically, they just changed how it operated. Instead of producing tested, production-ready versions, CentOS is merely a testing ground for RHEL. It is no longer, in my opinion, a good option for anyone who wants to run a stable server.

Current and Future CentOS Alternatives

So if you jumped on the CentOS 8 bandwagon, what should you put on your physical and virtual servers now? Well, you’ve got options.

Debian / Ubuntu

For those who don’t mind going to a very different kind of Linux, Debian has been the picture of OS stability and sysadmin-friendliness for a long time. If you want more frequent software updates, the Debian-based Ubuntu Server is popular and pretty good.

Oracle Linux

Yes, that Oracle has a RHEL-compatible Linux distribution of its own. But it’s not a clone, exactly. I mean, this is Oracle. It’s set up to use their tools and ecosystem, so I hope you like Oracle products. But hey, the OS itself is free!

ClearOS

ClearOS is another RHEL-compatible OS that’s mostly doing its own thing, though I’m not entirely sure what that thing is. Does the company have some deal with Hewlett-Packard? Anyway, they do have a free community edition and paid editions for home and business use.

The CloudLinux RHEL Fork

This is an upcoming release from the makers of CloudLinuxOS. It looks like they intend to load the new RHEL-based OS with some of their own tools, such as reboot-less server update tech. The first release is intended to be a more or less drop-in replacement for CentOS 8.

Rocky Linux

So the community that made and loved CentOS in the first place is, to say the least, ticked. They are so ticked that Greg Kurtzer (a co-founder of CentOS) has decided to do it all over again by making Rocky Linux and keep it in the community this time.

Again, the goal is to make a re-build of RHEL, a drop-in replacement for CentOS (at least for now). Eventually, the goal is to migrate from CentOS to Rocky Linux as easy as using a single, one-line command. The ETA for initial release isn’t quite set in stone, but I can personally vouch for how hard the community is working.

[See, full disclosure here… after writing this article, I joined the Rocky Linux documentation team.]

So Yeah, You Have Options

Some are out now, and others will be soon. Again, CentOS 8 will be supported until the end of 2021. CentOS 7, weirdly, will be supported until June 2024.

Migration shouldn’t be too complicated. Still, a pain in the rear that we have to do this at all, though.

How Engineers and CTOs Can Use a Simple, Universal Prioritization Technique Devised by Eisenhower

,

Are you familiar with any of the following scenarios?

  • We are never doing anything significant, neither benefitting ourselves nor humankind
  • We are always firefighting, stressed out, and going through mental trauma
  • We are doing considerable work but never on time, so we are missing out on the rewards

Instead, we should be doing substantial work at the right time so that both you and humankind are benefitted from your work. The question is, how.

Scaling Databases With EclipseLink And Redis

,

Overview

EclipseLink has two types of caches: the shared cache (L2) maintains objects read from database; and the isolated cache (L1) holds objects for various operations during the lifecycle of a transaction. L2 lifecycle is tied to a particular JVM and spans multiple transactions. Cache coordination between different JVMs is off by default. EclipseLink provides a distributed cache coordination feature that you can enable to ensure data in distributed applications remains current. Both L1 and L2 cache store domain objects.

“Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams.” — redis.io

How to Choose a Bare Metal Server From OVHcloud

,

There are dozens of factors that influence the UX of your site, app, or game. Most of them are beyond your control; user connection speed, end-system resources, even browser technology is all out of your hands. So when you do have the opportunity to influence your project’s infrastructure, you should seize it.

The world’s fastest muscle car can’t perform at its best when traffic is gridlocked bumper to bumper; likewise, the most finely tuned website can’t meet its potential running on shared hosting.

If you want your website, application, or service to run quickly and securely, maximizing both UX and SEO, then you need to look at the bare metal servers from OVHcloud.

Bare Metal Performance

Bare metal (or dedicated) servers aren’t uncommon. Still, most hosts only offer a single type of server, expecting small startups to pay for resources at the same rate as global giants, which can make dedicated hosting prohibitively expensive.

OVHcloud is different; it offers a range of bare metal server products optimized for a wide variety of challenges. That means small startups can invest in fast, easily scalable solutions that meet the most demanding security requirements without breaking the bank.

Whatever your aims, there’s a different OVHcloud solution configured for you:

OVHcloud Rise

Rise is the perfect option for a website, or web app hosting. With its low entry-cost, Intel-powered performance, bundled DDoS protection, and simplified administration, Rise is the natural choice for your first step into bare metal servers.

OVHcloud Advance

To meet SMEs’ need for reliable infrastructure to run mission-critical applications, OVHcloud configured Advance. From in-house CRMs to web-facing SaaS products, Advance is a solid foundation upon which to build your business.

OVHcloud Storage

Storage is ideal for storing large amounts of data securely. Hosting data on standard servers is a colossal waste of resources; with OVHcloud’s Storage product you can host up to 504TB and seamlessly access it via a performance-tuned server.

OVHcloud Infrastructure

For large companies with thousands of employees, global non-profits, colleges, and even local governments, OVHcloud Infrastructure offers scalability and flexibility beyond the average dedicated server.

OVHcloud High-End

For web apps that are leveraging cutting edge technology like machine learning and big data, OVHcloud’s High-End product is a no-compromise custom solution, the humdinger of bare metal servers, with every conceivable option available.

OVHcloud Game

If you’re developing video games, then lightning-quick, reliable streaming servers are essential. OVHcloud’s Game product delivers the type of speed your customers demand, with massive performance gains over comparable bare metal servers.

How to Choose a Bare Metal Server

It’s easy to get bogged down in detail, especially if this is your first foray into bare metal servers.

But here’s the good news: every OVHcloud bare metal server is a massive boost in performance over shared web hosting. That’s because, with a dedicated server, all of the server’s resources are…dedicated; that is, you don’t have to share with anyone. Shared hosting is pot-luck: You might wind up on a server with thoughtful users who don’t eat up all the resources, and you might end up on a server with one selfish user who hogs the processes and compromises the security. With a bare metal server, that’s not an issue.

Choosing a bare metal server is a two-step process. The first step is to think about what you intend to use it for:

Are you going to store a lot of data? If so, think about OVHcloud’s Storage product. But a lot of data doesn’t mean a WordPress blog. Let’s say you’re a polling company, collating millions of records that you hope to analyze to predict political movement; that requires a lot of storage. On the other hand, all servers have some storage. OVHcloud’s Rise product comes with 500Gb and can be configured with more. So if you’re planning to host something the size of a blog, then OVHcloud’s Storage might be using a sledgehammer to crack a nut.

The second step is to ask how complex the operations you’re going to ask the server to perform will be:

Hitting up a database to retrieve some data is not a complex operation. Even something like a complex search isn’t too taxing. If that’s the kind of process you expect to perform, OVHcloud’s Rise is more than adequate. But if you’re manipulating large amounts of data, like resizing hundreds of raster images dynamically; or using facial recognition to search through millions of biometric data records; or even managing your advertising application serving millions of ads to sites across the web; in those cases, you need the sort of performance OVHcloud’s Infrastructure product delivers.

OVHcloud’s products are all scaleable. Its High-End bare metal server product is entirely customizable. Whatever you choose, and however your needs change over time, you can be confident you’re running the optimum server for your project.

Why Choose OVHcloud

There are a mind-boggling array of processors, and OS, and a seemingly infinite — and increasingly expensive — amount of hardware on offer on the web. OVHcloud radically simplifies running a bare metal server by delivering a range of popular packages, tailored for everyday uses, that are both customizable and scaleable.

What OVHcloud delivers is a clear choice, letting you choose the right server for your product.

Whether you need lighting fast response times to maximize your SEO or the space to store a digital archive of the world’s most important art, for reliability and choice, opt for OVHcloud bare metal servers.

Le prédictif, l’allié d’une maintenance optimisée

, ,

La maintenance palliative cède progressivement la place à de la maintenance préventive, voire prédictive, grâce aux apports des capteurs et de l’Intelligence Artificielle. De nombreux industriels ont validé cette approche. Reste à passer à l’action.

La maintenance peut représenter de 10 % à 15 % des coûts de production. Le prédictif est en mesure d’aider à optimiser ces coûts. Toutefois, si 76 % des clients SAP interrogés pensent qu’il est important de pouvoir prédire la défaillance d’équipements, seuls 21 % sont satisfaits de leur politique de maintenance actuelle.

Mettre en place une maintenance prédictive demande :

  • des données de fonctionnement remontant rapidement et en quantité suffisante ;
  • l’utilisation d’algorithmes permettant de prédire les défaillances ;
  • l’appel à l’expertise des métiers : un élément clé de toute politique de maintenance.

Le recours à un jumeau numérique

« Les capteurs amènent un flot de données qui va remonter dans un jumeau numérique, lequel fonctionne en parallèle de l’équipement physique. Ce jumeau permet de prédire les besoins de maintenance, » explique Rodolphe Roy, directeur général d’ATS.

Réplique parfaite d’un objet ou d’un processus, le jumeau numérique est alimenté par les données venant du jumeau physique, ce qui permet d’en reproduire fidèlement l’état et de s’en servir comme base pour de la simulation.

« Il y a une vingtaine d’années, la simulation permettait de déterminer pourquoi les choses ne marchaient pas. Aujourd’hui, elle permet de prédire le fonctionnement physique d’objets très complexes, » témoigne Eric Bantegnie, vice-président et general manager Systems & Platform chez Ansys.

Le jumeau numérique ne répond pas seulement aux enjeux de maintenance, mais aussi aux enjeux de performance. « Nous pouvons dorénavant simuler le fonctionnement d’un processus de fabrication. Cela permet de confronter le résultat de la simulation aux performances du processus réel, afin de vérifier si son exécution est optimale. »

Enfin, l’utilisation des données d’exploitation est utile lors de la conception de nouvelles offres, qui ne repartiront alors pas d’une feuille blanche.

L’humain au cœur de tout

L’humain est essentiel dans la transformation des processus de maintenance. Les échecs dans les projets de transformation numérique sont en effet souvent liés à des soucis d’adoption des solutions et processus mis en place.

« C’est primordial, confirme Rodolphe Roy. Il faut accompagner cette transformation et aider à rapprocher les mondes de l’IT et de l’OT. L’IT doit proposer des outils parfaitement adaptés aux besoins des utilisateurs finaux, afin que cette courroie entre OT/IT ne se grippe pas. Il faut générer de la confiance : l’apport technologique ne doit pas inquiéter, mais au contraire rassurer. Il est crucial de repenser l’expérience homme-machine lors du passage à l’Industrie 4.0. »

La transformation numérique n’est pas seulement un défi, mais aussi une opportunité pour rendre l’industrie plus attractive et attirer de nouveaux talents. « Elle augmente la valeur des métiers et permet d’en créer de nouveaux, par exemple autour de la mise en œuvre et de la manipulation des jumeaux numériques, illustre Eric Bantegnie. L’opérateur de maintenance, spécialiste de la compréhension physique des équipements, gagne ainsi une compétence numérique. »

Vers du Product as a Service ?

La maintenance prédictive permet d’imaginer de nouvelles façons de commercialiser une offre, par exemple avec le Product as a Service, où c’est l’usage du produit qui est facturé et non le produit lui-même. Mais avant d’en arriver là, un défi attend les entreprises : le passage à l’échelle.

« Aujourd’hui, l plupart des industriels ont testé ces technologies, qui sont arrivées à maturité, explique Rodolphe Roy. Les grandes questions sont maintenant : comment passer à l’action ? Combien cela va-t-il me coûter ? Quel ROI attendre ? »

« Quelques centaines de milliers de jumeaux numériques seulement ont été déployés dans le monde, ajoute Eric Bantegnie. Mais nous sommes sur une trajectoire qui pourrait nous mener au milliard d’ici 3 à 5 ans. Il faudra toutefois savoir éviter une nouvelle guerre des standards, en assurant l’interopérabilité des solutions. »
