Meetup Paris #39 : The Five Foundations of Elasticsearch Performance

In this talk, we'll look at five lenses through which one can view the performance of an Elasticsearch clusters. Taking each in turn, attendees will come away with a set of principles and concerns through which they can monitor and understand the health and performance of their production Elasticsearch systems.

Kubernetes Phase 2-Key Challenges at Scale

Kubernetes is THE buzzword these days. Almost every IT organization is currently using it or is in the process of implementing it as part of their infrastructure. The transition to Kubernetes is complicated, whether a company is using an on-premises, cloud, hybrid, or managed solution, and it usually involves other changes in the codebase, such as shifting to a microservices architecture. While the implementation phase is led by the DevOps team, it requires the participation of the whole R&D group.

Yet another malware attack: macOS now the target for security attacks

Mac usage, as you’ve probably seen in your workplace, has risen exponentially in enterprises. According to a Jamf survey, 74 percent of those who previously used a PC for work experience fewer issues now that they use a Mac. Just like you’ve been watching the rapid rise of Macs in enterprises, so have attackers—the ones wreaking havoc in enterprises through malware attacks.

The life of a sysadmin: Encircled by excessive tools

It’s 3am, and you’re woken up by frantic calls and messages from users at your company—this is the everyday life of a sysadmin. Constantly surrounded by numerous tickets and persistent users who require immediate solutions, the life of a sysadmin is not a bed of roses. Their tasks are not limited to server management, maintenance, and repair, but also completely supporting a smoothly running production environment with minimal or no complaints from end users.

Fixing Native Apps with Sentry

Whether it’s a computer game, IoT device, or high-performance backend, chances are you’re using a native language to develop this application. Hands down, by far the most popular choices today for native application development are C and C++. Okay, maybe not the most popular, but definitely the most prevalent. Some might even say “inevitable.”

September 2019 Online Meetup: Implementing Infrastructure as Code

Infrastructure-as-Code, a DevOps best practice, is a workflow that involves managing and configuring your environments through source control. This allows teams to move faster and with fewer errors when making changes to production environments. If a mistake does occur, your environment and apps can quickly be reverted back to a previous state. Save time, increase productivity, and reduce the cost of inevitable human error.

Python Profilers

Python performance measurement tools help us to identify performance bottlenecks in our app. This allows us to focus on the business logic as opposed to writing custom code, setting it up with our app, and then figuring out whether the results are accurate enough. These tools are well tested by the open source community and used by many companies to measure the performance of their web apps.
