SaaS is exploding and so it should; it takes commoditized work and infrastructure away from tech teams so that they can focus on differentiating features. But what happens when it goes wrong? How do SaaS platforms make sure they aren't letting their customers down and in turn, letting their customers down? Observability, bolstered with AI gives all the partners the best chance to optimize availability and customer experience. Here's how.

As Kubernetes becomes the key target environment across many organizations, it automatically becomes an essential topic for developers. However, Kubernetes was created for operations and, unless you spend a considerable amount of time learning and specializing yourself, it is still challenging to use. Developers should rather focus on delivering applications instead, and a developer or application-focused platform is needed to enable that.

In one of our preceding blogs, we spoke about Software-Defined Networking (SDN) and the key drivers behind it. Virtualisation is one of the fundamental aspects that characterises SDN, and has influenced the architecture of network switching in the data centre. OVS (Open vSwitch) is a fundamental component of modern and open data centre SDNs, where it aggregates all the virtual machines at the server hypervisor layer.

This is the second part of the two-part blog series covering embedded Linux systems and the challenges brought about by the proliferation of Internet of Things (IoT) devices. In Part I, we surveyed the embedded ecosystem and the role Linux plays within that space. This blog takes you on the next step in the journey, where we explore the most demanding challenges facing manufacturers of tightly embedded IoT devices.

In the relatively short window of time that Kubernetes has been around, it’s rapidly matured as a critical technology foundation for the cloud, and now even applications that were previously thought to be unviable for containers are running with Kubernetes. As companies expand their usage of it, the need to operationalize Kubernetes with automation and optimization is critical to maintaining speed, agility and control in the long-term.

The cloud native revolution brought by Kubernetes has transformed the way we build and deliver software, but the world of big data has for too long been left on the side of this transformation. Thanks to many contributions from the open source community, Apache Spark integration on top of Kubernetes is now officially generally available with the recent releases this year.

Since we launched Qovery in January 2020, we offered free hosting ("Community" plan) for every developer. Providing free hosting was the perfect way to get product feedback and iterate with our users without the cost constraint. As our hosting infrastructure costs have drastically grown within the last 18 months, we had to reinvent our free offer. In a nutshell, we will continue to offer free hosting to involved community members only. Keep reading to know more 👇

Code signing is an important part of testing and distributing your desktop and mobile applications. It ensures that the end user’s system can verify the legitimacy of your application. Because of the need for security around signed certificates, they are stored locally and not uploaded to the cloud. This constraint could prevent your team from fully automating your CI/CD pipeline.

At DevWeek Austin, we discussed how AI and ML have come to the DevOps toolchain and are a great fit! Here are the 3 main takeaways.

In an on-premises environment, you have to pay for the capacity you have regardless of whether you’re using it, and you can’t exceed that capacity without purchasing and provisioning new hardware. In the cloud, however, you have much more flexibility thanks to cloud elasticity, which is the ability to automatically provision or deprovision resources based on workload changes.

This tutorial shows you how to set up a Ubuntu Desktop on Google Cloud. If you need a graphic interface to your virtual desktop on the cloud, this tutorial will teach you how to set up a desktop environment just like what you can get on your own computer. We need four steps to set up a machine.

Enterprises worldwide are embracing innovations such as the cloud to solve their digital needs, but many face challenges with workload migration and application modernization. One way organizations can ease their application modernization journeys is to adopt the 5 R’s framework—rehost, replatform, refactor, retain, and retire—allowing them to choose the right migration strategy for their specific environment.

Sometimes, managing several input fields gets crazy complex. You may need to recreate the same thing for each form and that’s can be really time-consuming. With a reusable Text Input in React, you can create just one input element in just one component and reuse it everywhere in any form. Let’s do this.

Summary The cloud is always innovating. One of the more recent and large breakthroughs has been the advancement and improvements in CPU architectures. Specifically with ARM CPU processors, where we are seeing adoption across all forms of computing, not only cloud, but also laptops with Apple’s M1, and of course in the past decade with mobile phones. The more recent availability in cloud computing therefore is not surprising, given the progress made in all other areas of technology.

This is the most exciting feature we launched since Qovery v2 has been released - the Preview Environment feature!

Microservices have significantly altered the architecture of server-side processors. Rather than a single massive monolithic codebase containing all of your application’s business logic, microservices adhere to the distributed systems concept, in which a collection of application components collaborate to meet business goals. You may create a streamlined microservices ecosystem free of superfluous architectural complications by adhering to microservices industry standards.

AWS Fargate is a serverless compute engine that allows you to deploy containerized applications with services such as Amazon ECS without needing to manage the underlying virtual machines.

Most computing devices today are likely to have an Intel processor, or an ARM (Advanced RISC Machine) processor, such as the CPU in your smartphone or tablet. Both chip architectures are optimised for low-power operation in order to provide mobile devices with the long battery life they require. However, they reflect different mindsets from a technical standpoint.

Six tips on how Site Reliability Engineers (SREs) can prepare for the reliability challenges of Black Friday and Cyber Monday 2021

The dynamic nature of cloud native applications is both a blessing and a curse. The ability to use compute, storage, and network resources without managing physical hardware is a real blessing. Your applications can take advantage of the seemingly limitless resources available in the public cloud. Unfortunately, the curse becomes clear when the bill arrives! It is a significant CloudOps challenge to find the balance between providing optimal application performance and minimizing cost.

Linux is an open-sourced operating system for computers, smartphones, servers, mainframes, and embedded devices. The main advantage of Linux over other operating systems is that Linux is an open-source operating system, which means that you can view, edit, customize, enhance, and share the code with anyone. The release of Linux garnered a huge community of contributors that created a variety of features and distributions for users at no added cost.

“Hello everybody out there using minix – I’m doing a (free) operating system (just a hobby, won’t be big and professional like gnu) for 386(486) AT clones. The above is an excerpt from Linus Torvalds’ original announcement of what came to be known worldwide as the Linux operating system (OS), dated August 1991. In hindsight, it is inconceivably modest now that we are in a much better position to appreciate the full revolutionary extent of his post.

Today, Kubernetes 1.23 release candidate was made available upstream for testing and experimentation.

The MSIX orb is the first “Windows-only” orb from CircleCI. When Microsoft approached us with the opportunity to build an orb that would help Windows developers build on our platform, we were enthusiastic. Most of our orbs, and general workload, revolve around Linux and utilize Bash. However, we recognized the deep need to provide good CI/CD solutions for building applications on Windows, and with use of PowerShell growing steadily within Linux, it was time to take the plunge.

True work revolves around the access and modification of files, and what better way to store and distribute work files than through a file server? The central-access model for storing and managing files brings many benefits to an organization. Most importantly, everyone can access a single, accurate version of any file on the server. Easy as that sounds, this feat is only possible with proper file server management.

An exponential increase in the generation of data led to the rise of the Big Data era. Among other factors, the cost of scaling up businesses to accommodate so much data prompted many businesses to switch to virtual cloud platforms. The cloud can store, organize, and manage all the data and applications for a company in a virtual environment. Monitoring this environment is crucial, because it’s susceptible to cyberthreats, like data breaches.

IT operations data grows by the year. Some estimates suggest that the average IT operations team watches their operational data volume double or triple every year. The result of this flood is that IT teams are grasping for any method they can find to make sense of all this data. Many teams are landing on AIOps as their solution to parse and categorize all of these events. AIOps isn’t a perfect fit for every organization, but it is a great fit for many.

If GitHub stars are any indication, Prometheus has been doubling in usage year over year since its inception. While at Moogsoft we love Prometheus as the metrics foundation of our observability platform, there were some challenges to overcome to make it the rock-solid piece of our stack it is today.

How well did 90s movies predict how technology should work and anticipate good DevOps practices? Here are some of our favorite movies, and whether we think they got it right or wrong.

Kubernetes is viewed as one of the great equalizers between development and operations teams. Simply write a manifest and the declarative power of Kubernetes is off to fulfill your desired state. Kubernetes is certainly pluggable and has the ability to be extended / opinions being swapped internally. As any IT organization can tell you, even with Kubernetes there is a lot of integration work, and several parts of the stack such as IaC have been left outside of Kubernetes.

Delivering both constant innovation and consistently great experiences with software offerings is becoming a critical business imperative in the new world of hybrid work. As a result, more companies are transforming to become software companies—creating the need to quickly and continuously upgrade software applications and technology foundations. Easier said than done? Not anymore.

In the past few years, the word “observability” has steadily gained traction in the discussions around monitoring, DevOps, and, especially, cloud-native computing. However, there is significant confusion about the overlap or difference between observability and monitoring.

Ubuntu is the platform of choice for deploying and running workloads on public clouds. No other operating system gives you better performance and consistency of experience across public clouds, including Amazon, Azure, Google, IBM and Oracle. There is a reason behind this exceptional experience. By design, Ubuntu images in public clouds include an optimized Linux kernel for each cloud, giving you the best performance and functionality across all instance types and services.

As a leader in the travel industry, Sabre Corporation is driving innovation in the global travel industry and developing solutions that help airlines, hotels, and travel agencies transform the traveler experience and satisfy the ever-evolving needs of its customers.

NestJS is fast becoming the de facto framework for NodeJS projects. Unlike older frameworks, NestJS was built with TypeScript, which has become commonplace in the JavaScript community. Frameworks like NestJS seem to be preferred by teams that adopt TypeScript. NestJS supports building APIs in REST and GraphQL. The goal of this tutorial is to show how you can add unit and integration tests to a NestJS GraphQL project and automate the testing process with CircleCI.

Making an Open Source Software with sensitive data and dozens of external integrations is a real challenge, here are feedbacks and tradeoffs we've made.

At incident.io, we're acutely aware that we handle incredibly sensitive data on behalf of our customers. Moving fast and breaking things is all well and good, but keeping our customer data safe isn't something we can compromise on. We run incident.io as a multi-tenant application, which means we have a single database (and a single application).

To understand what Kubernetes (K8s) is, you need to understand the technological developments that preceded it. In this article, you will learn what K8s is, how it evolved and why you should care.

I am a big proponent of cross-functional alignment, as I remnded our ELT at a recent off-site meeting. There’s a lot of buzz about FinOps bringing financial accountability to cloud spend by eliminating procurement siloes and implementing cross-functional best practices. As the CFO of a SaaS company, I fully support this practice. In fact, Virtana recently made some changes to our cloud infrastructure as part of our own evolution.

Cloud computing is the on-demand availability of computer system resources without direct active management by the user. Instead, the delivery of said resources is available over the internet, which has made cloud computing a popular digital service that various industries use to operate and manage work tasks. How cloud computing services are implemented, hosted and accessed by users is called cloud deployment. There are different types of deployments, each with defined advantages for users.

In August 2016, the United States government announced a new federal source-code policy, which mandates that at least 20% of custom source code developed by or for any agency of the federal government must be released as open-source software (OSS). The memo of this policy also states that the Federal Government spends more than $6 billion each year on software through more than 42,000 transactions. Obviously, this is a huge business for all open-source developers.

Let’s say you are writing a shell script for a systems housekeeping task. Perhaps the script is uploading backups to a remote server, or it is cleaning up old data, or it is making a measurement and submitting it to a somebody else’s HTTP API. What is the least cumbersome way for the script to contact you in case of problems? Let’s say you want to be contacted via email – how to make it work?

Session Replay enables you to replay in a video-like format how users interact with your website to help you understand behavioral patterns and save time troubleshooting. Visibility into user sessions, however, can risk exposing sensitive data and raise privacy concerns. For example, a user session may include typing in a credit card or social security number into an input field.

Five worthy reads is a regular column on five noteworthy items we’ve discovered while researching trending and timeless topics. This week, we explore the rise of DaaS services across organizations, and the role it could play in the hybrid workplace of tomorrow. When we last wrote about the era of Everything as a service (XaaS), Desktop as a Service (DaaS) was still a relatively niche concept.

A history of Site Reliability Engineering from its origins at Google in 2003 to the present.

Kubernetes has become an ever-larger target for workloads across all industries. The public sector, in particular, experiences several hurdles in achieving effective utilization of this relatively new technology. Of particular concern for the public sector in the United States is the Federal Information Processing Standard (FIPS).

Without a doubt, cloud technology has saved numerous organizations from disruption. According to a report published by Allied Market Research, In 2019, the global cloud services market was valued at $325,689 million and is expected to reach $1,620,597 million by 2030, registering a CAGR of 15.8%. The pandemic has amplified the growth of the cloud service market.

Nowadays, staff in organizations are required to access multiple applications in their infrastructure. This can lead to the user having to manage multiple login credentials and passwords. There are many solutions available that provide a single sign-on (SSO) capability — such as Okta, LDAP, and Active Directory — which is becoming common practice across businesses.

AIOps is an approach to managing the exponential growth of IT operations and the complexity of new technology through the application of artificial intelligence (AI). IT infrastructure increasingly relies on complicated deployments, multi-cloud architectures, and huge amounts of data. Traditionally, the tech industry responds to complexity by applying extra brainpower to the problem, bringing in more engineers, developers, and management.

Fast build times are great, which is why we aim for less than 5m between merging a PR and getting it into production. Not only is waiting on builds a waste of developer time — and an annoying concentration breaker — the speed at which you can deploy new changes has an impact on your shipping velocity. Put simply, you can ship faster and with more confidence when deploying a follow-up fix is a simple, quick change.

Data center managers often struggle to accurately track and manage their data center parts inventory. Legacy management tools like Excel spreadsheets are commonly used, but they fail to support the complexity and distributed nature of modern data center environments. They are hard to use, difficult to maintain, time-consuming, and error-prone.

Many software developers build their product on Platform.sh. You can take several approaches, some of which are very straightforward.

“Adapt or die (and let others take your share of the cake)” is both an evolutionary law and a business law. Without going any further, today, the rise of new technologies and critical applications have led to a substantial change in data centers.

Deck the halls! It's time for the annual holiday Code Freeze, that festive time of year when businesses impose a precautionary halt to code changes and Operations should be quiet. But before you kick up your feet, make sure that demand doesn’t lead to availability embarrassments. After all, retail experts suggest that we’re in for another online-heavy holiday shopping season, so businesses need to brace for increased digital traffic...with little tolerance for failure.

For organizations growing larger by the day, network management becomes increasingly complex, and scaling to meet this growth can be a major headache. To battle such complexity without a graphic representation of a network is a tiresome task, which is where network diagram software comes in. Network diagram software allows a network admin to portray the network clearly and legibly through detailed graphics.

This is my fifth company as CEO and I’ve really come to enjoy working in B2B enterprise software – the proverbial “picks and shovels” end of our industry. In particular I enjoy innovating in spaces that may not be immediately obvious and typically overlooked in the mad gold rush of today’s frothy venture capital scene.

Mattermost v6.1 is generally available today and includes the following new features (see changelog for more details).

The world has changed since I started out on a help desk in Colorado 25 years ago. In those long ago years, a company’s desktop machines actually lived under the desks of many in the organization (and often doubled as a foot warmer!) and configuration was done machine by machine manually, or maybe even by some script that was created to run at login if we were lucky. If there were laptops in use by the business users, they were a lot less mobile and rarer than in today’s business world...

Tomas Fedor, Head of Infrastructure at Productboard, is here to talk about his personal passions and professional perfections.

Incidents are a great opportunity to gather both context and skill. They take people out of their day-to-day roles, and force ephemeral teams to solve unexpected and challenging problems. In my career, I've found incidents can be a great accelerator - for both myself and others around me. It was after leading my first incident at GoCardless that I started to feel really comfortable in the codebase and the team.

Remote server management is a proven strategy used for increasing the uptime and responsiveness of your IT infrastructure. It manages the performance, health, and utilization of remote servers or back-end systems on various networks. After reading this post, you’ll understand what remote server management is, how it works, and how to implement it.

Leveraging Terraform, which is an infrastructure-as-code platform, is a great match. Using both technologies together is becoming more mature and there have been some great pieces around the art of the possible between the two platforms. Though if you are unfamiliar with both, this guide will get you up and started with both Terraform and Shipa together. In this example will be using Terraform to create all of the necessary Shipa resources to deploy to a Kubernetes cluster.

In one of our previous articles, we discussed what an SRE is, what they do, and some of the common responsibilities that a typical SRE may have, like supporting operations, dealing with trouble tickets and incident response, and general system monitoring and observability. In this article, we will take a deeper dive into the various SRE principles and guidelines that a site reliability engineer practices in their role.

Tracing has become essential for monitoring today’s increasingly distributed architectures. But complex production applications produce an extremely high volume of traces, which are prohibitively expensive to store and nearly impossible to sift through in time-sensitive situations. Most traditional tracing solutions address these operational challenges by making sampling decisions before a request even begins its path through your system (i.e., head-based sampling).

Willy Tarreau, the founder of the HAProxy load balancer, 20 years past its initial, open-source release, still guides the project, often submitting code patches and writing long and meticulous replies on the community forum.
