Use HAProxy Response Policies to Stop Threats

HAProxy gives you an arsenal of sophisticated countermeasures including deny, tarpit, silent drop, reject, and shadowban to stop malicious users. There are two phases to stopping malicious users from abusing your website and online applications. Step one is detection, step two is deploying countermeasures. HAProxy is more powerful than nearly every other load balancer when it comes to both detection and countermeasures.

Accidental Cloud Administrator

Accidental DBA is a term most IT pros are familiar with, and traditionally it describes an “on-top task” for the SysAdmin. It was followed by the “involuntary security admin,” a task carried out by network admins, as back in the days it was all about securing the perimeter. Now there are the clouds, but whose responsibility is it? Surely the SysAdmin again, as it’s just about infrastructure? But then there’s VPNs and BGP and load balancers—network territory!

8 Tips for SRE Wellness

When planning the SRE from home virtual even last month, one of the central themes was wellness and the need for self-care for SREs, especially during this time of crisis. Knowing how stressful an SRE’s day can be, combined that with a global pandemic and new working conditions, we knew we needed programming around SRE and IT wellness for SRE from Home.

Authenticate Puppet Enterprise with FreeIPA using LDAP

Using a Linux Domain controller such as Red Hat Identity Management or FreeIPA? If so then the fields are a bit different than some other LDAP interfaces, which makes it difficult for some to connect to for authentication. Here is a quick how-to on setting up Puppet Enterprise with authentication from FreeIPA. I am assuming that you already have Puppet Enterprise installed with eyaml configured. If not, then you may want to visit these prerequisites.

August 2020 Online Meetup - Rancher 2.5 Preview - EKS Lifecycle Management

Hosted cloud provider Kubernetes services like EKS alleviate the operational burden of Kubernetes. The cluster operator is still responsible for upgrades and all the day 2 operations for the applications running on the cluster. In this meetup we'll discuss how Rancher can help manage the lifecycle of EKS clusters, and will walk through importing existing and provisioning new EKS clusters through Rancher. We will also look at how to deploy Rancher logging and monitoring onto the cluster to handle day 2 operations on the cluster.

Azure Durable Functions CI/CD Issue Solved!

This blog explains a peculiar issue faced when Azure Durable Functions are deployed using Azure DevOps. In case you need to know what Azure Durable Functions are, please refer to Microsoft’s documentation on Durable Functions here as the explanation of it, is not under the scope of this blog.

Creating Memorable Gaming Experiences with Kubernetes

If you’re a gamer, you probably know how immersed you can get in your favorite game. Or if you’re the parent or partner of a gamer, you probably know what it’s like to try to get the attention of someone who is in “gaming mode.” Creating worlds and enriching players’ lives is in Ubisoft’s DNA.

The Netdata Community Powered by NodeBB

We recently adopted NodeBB as our software of choice for building the Netdata Community. We have many good reasons for why we wanted to provide our community with a proper home online, but I wanted to cover some of the technical reasons for choosing NodeBB for our platform, and the many parallels between the NodeBB and Netdata projects, which was certainly a driving force behind this decision.

In-house vs. MetricFire

You’re ingesting 20,000 data points a second, in 400,000 metrics, from thousands of AWS instances – and your monitoring can’t handle the load. You need a scalable, highly-available monitoring and dashboarding solution (and you need it yesterday). Should you do it yourself with an in-house Graphite or Prometheus monitoring system? Or will you skip the headache and choose a hosted service like MetricFire?
